influx bucket create
This page documents an earlier version of InfluxDB. InfluxDB v2.2 is the latest stable version. View this page in the v2.2 documentation.
The
influx bucket create command creates a bucket in InfluxDB.
Usage
influx bucket create .
- explicit. | https://docs.influxdata.com/influxdb/v2.0/reference/cli/influx/bucket/create/ | 2022-05-16T07:45:49 | CC-MAIN-2022-21 | 1652662510097.3 | [] | docs.influxdata.com |
Defining Repository-Level Detection Rules
Some repositories may have specific requirements for vulnerability detection which differ from the rules defined globally.
To address repository-specific needs, you can use a per-repository configuration file. This file is committed to an individual repositories and affects only the repository where they are committed. When this option is enabled, Security for Bitbucket looks for a file named
soteri-security.yml at the root of the repository. You will need to create and commit this file yourself if the repository has no
soteri-security.yml yet.
Rules and options configured in this file are used both when repository content is updated (if Soteri - Scan Commits hook is enabled) and when you trigger scan manually from Security Scan tab of the repository.
As of version 3.10.0, this file is always loaded from the latest commit of the default branch. This ensures that scans of even historical branches are conducted with the most up-to-date configuration.
Per-repository configuration is disabled by default. The global settings page has a toggle to enable custom repository rules support:
Supported Configuration
This table documents all supported
soteri-security.yml configuration options.
Below is an example of a
soteri-security.yml config:
inherit_builtin_rules: false inherit_custom_rules: false rules: - RSA_PRIVATE_KEY - SSH_PRIVATE_KEY custom_rules: # Comments are supported. BITCOIN_ADDRESS: '^[13][a-km-zA-HJ-NP-Z0-9]{26,33}$' YOUTUBE_LINKS: '<a\s+(?:[^>]*)href=\"((?: allowlist_paths: - config/server.yml - (.*)\.insecure
Pre-Receive Hook
When Security for Bitbucket is installed and enabled, any changes which might invalidate
soteri-security.yml on the default branch will be blocked by an included pre-receive hook. Changes which can be rejected must both:
Target a repositoryโs default branch. This includes:
Direct pushes to the default branch.
The merging of pull requests which target the default branch.
Modify
soteri-security.ymlsuch that it is no longer valid. Examples of potential reasons
soteri-security.ymlcould be invalid:
Doesnโt parse as a valid YAML. You can use online tools to check that your YAML is valid before committing, like this one.
Note that the YAML standard forbids tab characters. You must use spaces in
soteri-security.yml.
Properties donโt parse as expected (e.g.
inherit_builtin_rulesmust be parsable as a boolean).
Provided regular expressions are invalid (e.g. for
allowlist_pathsor any defined
custom_rules). You can use online tools to validate that your regexes are valid before committing, like this one.
Rule names that donโt have regular expressions associated with them. | https://docs.soteri.io/security-for-bitbucket/3.15.1/Defining-Repository-Level-Detection-Rules.14594277382.html | 2022-05-16T09:27:06 | CC-MAIN-2022-21 | 1652662510097.3 | [] | docs.soteri.io |
After you allocate the newValues buffer, fill the buffer with the desired element value for each element in the specified range, in row-major order. For each element to be modified, fill the buffer as follows:
- The first 4 bytes should describe the size of the data. This is only applicable for variable-length element data types.
- The remaining bytes allocated for each element are allocated to hold the maximum size of the element data type. This space should contain the new element value.
Therefore, for each element, space is allocated as:
- (MAX_SIZE_OF_ELEMENT_DATA_TYPE + 4 bytes) for variable-length element data types.
- (MAX_SIZE_OF_ELEMENT_DATA_TYPE) for fixed-length data types. | https://docs.teradata.com/r/Teradata-VantageTM-SQL-External-Routine-Programming/July-2021/C-Library-Functions/FNC_SetArrayElementsWithMultiValues/Usage-Notes/Filling-the-newValues-Buffer | 2022-05-16T08:59:44 | CC-MAIN-2022-21 | 1652662510097.3 | [] | docs.teradata.com |
An unique advantage of TX Spell .NET is that a single instance of the spell check component can be used to provide spell checking capabilities to an unlimited number of controls. To enable spell checking for a TextControl, the SpellChecker property of TextControl must be simply set to the specific TXSpellChecker instance.
The source code is contained in the following directories:
If a customizable SpellCheckDialog is used, the Proofing.TXSpellChecker.SpellCheckDialogClosing event can be used to link to another TextControl when the current control has been checked completely. This allows to usage of one instance of the dialog to spell check an unlimited number of TextControls.
private void txSpellChecker1_SpellCheckDialogClosing(object sender, TXTextControl.Proofing.SpellCheckDialogClosingEventArgs e) { if (e.StateManager.NextMisspelledWord != null) { // The dialog was closed by user before checking all misspelled words. return; } e.Cancel = SetNextTextControl(e.StateManager, curTextControl); }
Private Sub txSpellChecker1_SpellCheckDialogClosing(sender As Object, _ e As TXTextControl.Proofing.SpellCheckDialogClosingEventArgs) If e.StateManager.NextMisspelledWord IsNot Nothing Then ' The dialog was closed by user before checking all misspelled words. Return End If e.Cancel = SetNextTextControl(e.StateManager, curTextControl) End Sub
Start the sample application and click on the button Spell Check Dialog. The dialog checks each of the four TextControls and every contained TextPart such as headers, footers or text frames. | https://docs.textcontrol.com/spell/windows-forms/article.winforms.textcontroldialogonmultiplecontrols.htm | 2022-05-16T08:36:31 | CC-MAIN-2022-21 | 1652662510097.3 | [] | docs.textcontrol.com |

Replicate an organization
The state of an organization consists of metadata (dashboards, buckets, and other resources) and data (time-series). An organizationโs state at a point in time can be replicated to another organization by copying both metadata and data. To replicate the state of an organization:
Create a new organization using the InfluxDB Cloud sign up page. Use a different email address for the new organization.
Replicate metadata.
Use an InfluxDB template to migrate metadata resources. Export all resources, like dashboards and buckets, to a template manifest with
influx export all. Then, apply the template to the new organization.
Replicate data.
Use one of the methods below to copy data to the new organization:
Re-invite users.
Export data to CSV
- Perform a query to return all specified data.
- Save the results as CSV (to a location outside of InfluxDB Cloud).
- Write the CSV data into a bucket in the new organization using the
influx writecommand.
Write data with Flux
Perform a query to return all specified data.
Write results directly to a bucket in the new organization with the Flux
to() function.
If writes are prevented by rate limiting,
use the
influx write --rate-limit
flag to control the rate of writes.
For more information on rate limits in InfluxDB Cloud,
see Exceeded rate. | https://docs.influxdata.com/influxdb/cloud/organizations/migrate-org/ | 2022-05-16T09:21:51 | CC-MAIN-2022-21 | 1652662510097.3 | [] | docs.influxdata.com |

The following example demonstrates how to determine whether the stylus is inverted. This example assumes that there is a TextBox called
textBox1 and that the PreviewStylusInRange event is connected to the event handlers.
void textbox1_PreviewStylusInRange(object sender, StylusEventArgs e) { if (e.StylusDevice.Inverted) { textbox1.AppendText("Pen is inverted\n"); } else { textbox1.AppendText("Pen is not inverted\n"); } }
Private Sub textbox1_PreviewStylusInRange(ByVal sender As Object, _ ByVal e As StylusEventArgs) Handles textbox1.PreviewStylusInRange If e.StylusDevice.Inverted Then textbox1.AppendText("Pen is inverted" & vbLf) Else textbox1.AppendText("Pen is not inverted" & vbLf) End If. | https://docs.microsoft.com/en-us/dotnet/api/system.windows.input.stylus.previewstylusinrange?view=netcore-3.1 | 2021-02-25T09:27:49 | CC-MAIN-2021-10 | 1614178350846.9 | [] | docs.microsoft.com |
npm.
"scripts"
"command"
run[-script]
As of [email protected], you can
use custom arguments when executing scripts. The special option -- is used by
getopt to delimit the end of the options. npm will pass
all the arguments after the -- directly to your script:
[email protected]
--
npm run test -- --grep="pattern"
The arguments will only be passed to the script specified after npm run
and not to any pre or post script.
npm run
The env script is a special built-in command that can be used to list
environment variables that will be available to the script at runtime. If an
"env" command is defined in your package, it will take precedence over the
built-in.

If you try to run a script without having a node_modules directory and it fails,
you will be given a warning to run npm install, just in case you've forgotten.
node_modules
npm install
You can use the --silent flag to prevent showing npm ERR! output on error.
--silent

You can use the --if-present flag to avoid exiting with a non-zero exit code
when the script is undefined. This lets you run potentially undefined scripts
without breaking the execution chain.

9. Poppy humanoid: wiring arrangement
9.1. Data and power buses
Before you can startup your robot, let's have a look at the cables. You must connect wires from motors to motors by forming 2 different buses:
- Upper body (from
head_yto
abs_x)
- Lower body (from
r_hip_zand
l_hip_zto
r_ankle_yand
l_ankle_y)
These 2 buses are fully disconnected from each other (1), they have their own:
- Power supply (SMPS2Dynamixel + wall socket)
- Dynamixel hub to plug up to 6x motors
- USB2AX
The drawing below shows the 2 data and power buses: cables connecting motors are in red, data hubs and SMPS power injection in green.
(1) N.B.: If you own a single power supply unit, you may connect both power buses together by adding a 4-wire cable and cutting out its data bus so that only 1 SMPS2Dynamixel is powered, as shown in the video. But this is unnecessary in most cases since robots are sold with 2 power supply units.
Both USB2AX adapters have to be plugged to the USB sockets of the Raspi3 at the bottom of the head. If you mess up with wiring, at first startup, software will report missing motors or too much motors or the same bus.
9.2. Power supplies for Poppy Humanoid
The robot requires 3 power supply cables:
- 12V power supply for the SMPS2Dynamixel of the upper body
- 12V power supply for the SMPS2Dynamixel of the lower body
- 5V micro USB power supply for the Raspberry Pi 3
For now you can plug the 3 cables to the robot but wait a bit before connecting them to the wall socket. Indeed, there's a few things we need to setup before we can start the software.
9.3. Connect to the robot
Let's getting started with software! Please checkout the dedicated section: Getting started with Poppy software. Psst, before you leave: don't forget to fasten the last screws to fix your head face after you got it working from software.

Current User
After a successful Login or Register request, the Current User is automatically set. Current User automatically logs in every time your application loads, if there was one when the app closed. You will need to Logout to clear it.
Auto Login
The easiest way to implement Auto Login in your application is by checking if there is a Current User during the load of your Launch Screen and perform a Screen Navigation to the authenticated users section of your app.
- Create a new Screen Navigation that presents the first screen that your authenticated users should see when open the app. Tip: We would suggest setting its type to Set as Root Screen.
- Open the Screen that you have set as Launch Screen. This is the screen that will be loaded first when your application starts.
- Create a new Function that performs the Screen Navigation from the step 1, if Current User is Logged In.
- Create a new Execute a Function Event Action in the When Screen First Loads Event.
Bind Current User values
You can use the values of the Current User properties when you need to bind dynamic parameter values.
Code Blocks
Current User
Using the Current User Code Block, you can access all the Current Userโs properties. You can connect it to Get Value and Set Value Code Blocks to access or change a propertyโs value.
Get Current User Id
Get Current User Id Code Block returns the Record Id of the Current User in case you need to use it in a Function.
Current User Is Logged In
You can use this Code Block in combination with an If Code Block in order to execute different flows in your app, based on if the user is authenticated. You can check Auto-Login section.
For example, you can allow the press of a button to the authenticated users, and navigate the non-authenticated to a Login Screen.

How to setup your Two-Factor authentication.
Before starting, download and install the 'Google Authenticator' app in your smartphone or tablet (iOS, Android, Blackberry, Windows Phone)
After you have successfully logged into Niagara, either using password or keys, type this command in the command line:
$ autenticator_setup
Your terminal screen will clear and display this message:
**************************************************************** You have about to setup your Two-factor authentication. Please download and install the 'Google Authenticator' app in your smartphone or tablet (iOS, Android, Blackberry, Windows Phone), then press 'Enter' to continue or Ctrl-C to exit without setup. ****************************************************************
Press <enter> to continue. You will get this next message. Read it carefully:
**************************************************************** Google Authenticator is going to generate your new secret key. A lot of output will scroll past, including a large QR code. At this point, 60 seconds in your app. If the QR code is too big to see it completely, you may reduce the font size of your terminal window and enlarging the window again. Press 'Enter' to continue or Ctrl-C to exit without setup. ****************************************************************
Press <enter> to continue. You will get this next message. Read it carefully:

Keep your scratch codes in the good old fashion way: in a piece of paper in your wallet. Do not keep them in your phone or your computer The scratch codes are used when you cannot generate a new One-Time Code. For example, if you have lost your phone. A scratch code will give you access to the system while you recover your phone; scratch codes can be used only once. Please login again. You will be prompted for the One-Time Code after you sucessfully authenticate. Press 'Enter' to continue
You are all set!
You can now logout and login again. This time the system will ask for your One-Time Password. You just get it from your smartphone (or tablet).
You data is now safely protected.
Probably, the QR code will not fit your screen so you may not be able to scan it. The URL above,..., will show you a smaller version of the QR code in your browser. Please have in mind that pasting that URL into your browser exposes the OTP secret to Google.
Another way to make you QR code fit the screen is to reduce the font size of your terminal window; your windows will shrink, but then you can maximize the window and most likely you will be able to scan the code. | https://docs.scinet.utoronto.ca/index.php?title=Two-Factor_setup&oldid=2667&diff=prev | 2021-02-25T08:08:59 | CC-MAIN-2021-10 | 1614178350846.9 | [] | docs.scinet.utoronto.ca |
The bit level data interchange formatยถ
Introductionยถ
Bitproto is a fast, lightweight and easy-to-use bit level data interchange format for serializing data structures.
The protocol describing syntax looks like the great protocol buffers , but in bit level:
message Data { uint3 the = 1 uint3 bit = 2 uint5 level = 3 uint4 data = 4 uint11 interchange = 6 uint6 format = 7 } // 32 bits => 4B
The
Data above is called a message, it consists of 7 fields and will occupy a total
of 4 bytes after encoding.
This image shows the layout of data fields in the encoded bytes buffer:
Featuresยถ
Supports bit level data serialization.
Supports protocol extensiblity, for backward-compatibility.
- Very easy to start:
Protocol syntax is similar to the well-known protobuf.
Generating code with very simple serialization api.
- Supports the following languages:
C (ANSI C) - No dynamic memory allocation.
Go - No reflection or type assertions.
-
Blazing fast encoding/decoding (benchmark).
Code Exampleยถ
Code example to encode bitproto message in C:
struct Data data = {}; unsigned char s[BYTES_LENGTH_DATA] = {0}; EncodeData(&data, s);
And the decoding example:
struct Data data = {}; DecodeData(&data, s);
Simple and green, isnโt it?
Code patterns of bitproto encoding are exactly similar in C, Go and Python. Please checkout the quickstart document for further guide.
Why bitproto ?ยถ
There is protobuf, why bitproto?
Originยถ
The bitproto was originally made when Iโm working with embedded programs on micro-controllers. Where usually exists many programming constraints:
tight communication size.
limited compiled code size.
better no dynamic memory allocation.
Protobuf does not live on embedded field natively, it doesnโt target ANSI C out of box.
Scenarioยถ
Itโs recommended to use bitproto over protobuf when:
Working on or with microcontrollers.
Wants bit-level message fields.
Wants to know clearly how many bytes the encoded data will occupy.
For scenarios other than the above, I recommend to use protobuf over bitproto.
Vs Protobufยถ
The differences between bitproto and protobuf are:
bitproto supports bit level data serialization, like the bit fields in C.
bitproto doesnโt use any dynamic memory allocations. Few of protobuf C implementations support this, except nanopb.
bitproto doesnโt support varying sized data, all types are fixed sized.
bitproto wonโt encode typing or size reflection information into the buffer. It only encodes the data itself, without any additional data, the encoded data is arranged like itโs arranged in the memory, with fixed size, without paddings, think setting aligned attribute to 1 on structs in C.
Protobuf works good on backward compatibility. For bitproto, this is the main shortcome of bitproto serialization until v0.4.0, since this version, it supports messageโs extensiblity by adding two bytes indicating the message size at head of the messageโs encoded buffer. This breaks the traditional data layout design by encoding some minimal reflection size information in, so this is designed as an optional feature.
Shortcomesยถ
Known shortcomes of bitproto:
bitproto doesnโt support varying sized types. For example, a
unit37always occupies 37 bits even you assign it a small value like
1.
Which means there will be lots of zero bytes if the meaningful data occupies little on this type. For instance, there will be
n-1bytes left zero if only one byte of a type with
nbytes size is used.
Generally, we actually donโt care much about this, since there are not so many bytes in communication with embedded devices. The protocol itself is meant to be designed tight and compact. Consider to wrap a compression mechanism like zlib on the encoded buffer if you really care.
bitproto canโt provide best encoding performance with extensibility.
Thereโs an optimization mode designed in bitproto to generate plain encoding/decoding statements directly at code-generation time, since all types in bitproto are fixed-sized, how-to-encode can be determined earlier at code-generation time. This mode gives a huge performance improvement, but I still havenโt found a way to make it work with bitprotoโs extensibility mechanism together.

Managing drive arraysยถ
Drives are iSCSI based block devices attached to servers at runtime. They can be operating system drives or unformatted drives.
Drive arrays are collections of identical drives that users can control as a single entity.
Creating a drive array using the UIยถ
There are multiple ways to create a drive array from the Infrastructure Editor:
- Click on on an instance array and go to the DriveArrays tab
- Click on Create DriveArray button
Listing drive arrays of an instance array using the UIยถ
- Click on on an instance array and go to the DriveArrays tab
Adding a new driveยถ
1.In the Bigstep Infrastructure Editor, click on the Infrastructure button on the left bar and select Drive Array.
2.The new Drive Array will now be visible in the interface.
3. Click on the new Drive Array, in order to customize it. You can tweak the size, storage type, operating system template, file system and block size, as well as attach it to an existing Instance Array or Container Array. You can also attach it to an array by simply dragging and dropping it in the interface.
4. An alternative way to create a Drive Array is from the Instance Array overview, in the DriveArrays tab. Click on Create DriveArray and a new one will be attached to the server, with default settings. You can customize the Drive Array by clicking on its icon in the interface.
5.After configuring and attaching the drive, click on Deploy Changes in order to make it active.
6.The new disk will be attached to your server after the deploy. A server reboot might be needed, as well as additional configuration from your operating system, before it can be used.
Removing a driveยถ
1.In order to delete an existing Drive Array, click on its icon in the infrastructure editor.
2.Click on Delete DriveArray.
3.Confirm that you want to delete the drive.
4.Click on Deploy Changes in the infrastructure editor.
5.As a safety measure, you will be warned about data loss. In order to confirm your option, manually type destroydata before the actual deploy starts.
6.The drive will be deleted at the end of the deploy.
Expanding disk sizeยถ
1.From the infrastructure editor, click on the DriveArray you want to change the Drive size of. This opens the DriveArray overview panel.
2.Drag the Default drive size slider in order to increase its capacity, or simply type the desired size in GB. It is not possible to reduce the size of a drive, since this is a very risky operation on most operating systems.
3.Click on Save, then on Deploy changes.
4.Resizing a disk requires that the server is powered off. If any affected servers in the infrastructure are still powered on, you will be prompted to Hard power off or Soft power off them before the deploy. We recommend the Soft power off option.
5.The resized disk will be available after the deploy. Depending on the operating system on your server, additional configuration might be required.
Creating a drive array using the CLIยถ
metalcloud-cli drive-array create -ia gold -infra complex-demo -size 100000 -label da
In order for a drive array to be accessible you need to push the Deploy changes button in the UI, or run the following metalcloud-cli command:
metalcloud-cli infrastructure deploy -id complex-demo
or
metalcloud-cli infrastructure deploy -id complex-demo -autoconfirm
Typically drive arrays will expand with their instance array. To stop that from happening use
-no-expand-with-ia
Listing drive arrays of an infrastructure using the CLIยถ
$ metalcloud-cli drive-array list -infra complex-demo Drive Arrays I have access to as user [email protected]: +-------+-------------------------------+-----------+-----------+-----------+-------------------------------+-----------+--------------------------+ | ID | LABEL | STATUS | SIZE (MB) | TYPE | ATTACHED TO | DRV_CNT | TEMPLATE | +-------+-------------------------------+-----------+-----------+-----------+-------------------------------+-----------+--------------------------+ | 47859 | da | ordered | 100000 | iscsi_ssd | gold (#37135) | 1 | | | 45928 | drive-array-45928 | active | 40960 | iscsi_ssd | workers (#35516) | 2 | CentOS 7.4 (#78) | | 45929 | drive-array-45929 | active | 40960 | iscsi_ssd | master (#35517) | 1 | CentOS 7.4 (#78) | | 47799 | gold-da | ordered | 100000 | iscsi_ssd | gold (#37135) | 1 | | | 47858 | test | ordered | 40960 | iscsi_ssd | | 1 | | +-------+-------------------------------+-----------+-----------+-----------+-------------------------------+-----------+--------------------------+ Total: 5 Drive Arrays
All the drive arrays with status ordered are not yet accessible.
Deleting a drive array via the CLIยถ
To delete a drive array use
metalcloud-cli drive-array delete -id 47859
Manually logging into the iscsi targetยถ
Most of the time the drives will simply appear in the operating system at a reboot. However sometimes manual intervention is required. Reffer to Manually managing iSCSI connections for more information. | https://docs.bigstep.com/en/latest/guides/managing_drive_arrays.html | 2021-02-25T08:12:42 | CC-MAIN-2021-10 | 1614178350846.9 | [array(['../_images/managing_drive_arrays1.png',

A role must be defined in the Roles Manager portlet in the Teradata Viewpoint portal before it can be assigned to a user. The Roles tab provides a list of available roles. Roles can be selected and assigned to the current user account.
You can assign roles to an existing Teradata Viewpoint user account. If your Teradata Viewpoint portal is configured to use auto-provisioning, a user account is created automatically the first time a user logs on to Teradata Viewpoint. By default, auto-provisioned accounts are authenticated externally and assigned a default role. The authentication source (for example, LDAP) and default role are set during configuration.
- From the Admin menu, open the Roles Manager portlet.
- From the Users view, browse the list of users or use the filters to find users.
- Select a user name.
- Click the Roles tab.Available roles are listed in the AVAILABLE PORTAL ROLES pane. Roles assigned to the user are shown in the ROLES FOR <User> pane.
- Select a role from the AVAILABLE PORTAL ROLES list or select multiple roles by pressing Shift or Ctrl.
- Click.The selected roles appear in the ROLES FOR <User> pane. In the AVAILABLE PORTAL ROLES pane, the assigned roles are dimmed.

Managing assetsยถ
Assets are files that are served at appropriate times via the DHCP, TFTP and HTTP mechanisms during PXE or ONIE.
There are 3 types of assets:
- text files stored in the DB (size limited to 4MB). These can also hold references to variables or secrets. MIME type:
text/plain
- binary files stored in the DB (size limited to 64MB). MIME type:
application/octet-stream
- external files referenced as an URL. MIME type:
text/plain,
application/octet-stream
Using text assets as file templatesยถ
If enabled, text files stored in the db can act as a template. When they need to be served t the user via HTTP or TFTP a search_and_replace will be executed for strings matching the provided list of params with the format
{{<VARIABLE_NODE>}}.
See Managing Variables and Secrets for more details.
Creating an URL assetยถ
metalcloud-cli asset create -url "%repoURL%/.tftp/boot/uefi-windows/bootx64.efi" -filename "bootx64.efi" -mime "application/octet-stream" -usage "bootloader" -return-id
Creating a text assetยถ
Creating an asset from a pipe:
echo "test" | metalcloud-cli asset create -filename "test.xxx" -mime "text/plain" -pipe -return-id
Creating a binary asset from pipeยถ
cat data.bin | metalcloud-cli asset create -filename "data.bin" -mime "application/octet-stream" -pipe -return-id
Associating assets with templatesยถ
Before assets can be used they need to be associated with a specific OS template. Associating an asset with a template at a specific path (
/bootx64.efi).
metalcloud-cli asset associate -id "bootx64.efi" -template-id windows2019 -path "/bootx64.efi"

To enhance the community engagement , it would be nice to create a path for career through this website. Stake Overflow for example has its own job portal and active participates in there would have better chance to land a job. While many of us participate here to learn more and help community , it is possible to motivate experts to join and participate our platform when they see it is a mean to improve their career. The key benefit of forum is learning and capacity building. For example, I am participating here because , I look into question and understand challenges for IT Professionals and while I look into the solution I learn a lot and when I come across similar problem in the real world, I will fix it right away and that is how I learn and gain experience. This is same for everyone who is actively participate in forums. Now, there should be a model to proof it and badge and number of contributions is one way to do it. In next step, this profile could be integrate into LinkedIn profile and show expertise for users in their profile as verified expertise. For example consider a user is very active in Microsoft Windows forum by number of answers and response, it is possible to add tag to his/her profile in LinkedIn like expertise in Microsoft Edge verified by Microsoft QnA. Then those who are looking for talents could find them easier in LinkedIn by verified expertise and it also motivate others to be active in this forum.
Since LinkedIn is part of Microsoft and doing so is not complex and just required implementation of some API and this could be an experience to move forward with other forums too. | https://docs.microsoft.com/en-us/answers/content/idea/277069/integration-with-linkedin.html | 2021-02-25T09:05:39 | CC-MAIN-2021-10 | 1614178350846.9 | [] | docs.microsoft.com |

Part 4 - Viewing Device Data
In Part 1, Part 2, and Part 3 of this walkthrough weโve created an API for our lลm smart plant mobile app that allows users to sign up, log in, and register devices. In this part weโre going to add the ability to view a list of devices owned by the current user and cover how to request historical device data.
The first endpoint weโll create is
GET /devices, which will return a list of all devices owned by the currently authenticated user.
- Set the
Methodto
GET.
- Set the
Routeto
/devices.
- Set the
Descriptionto anything you want.
- Set the
Access Controlto
Any authenticated user.
Like all endpoints weโve created, this one will also need a workflow with a matching endpoint trigger. Next, add a Get Device node that weโll use to look up the userโs devices.
- Set the
Find by...to
Tag Query. This allows us to query devices by their tags.
- Check the
Return multiple devices?checkbox.
- Add a tag query and set the
Key Templateto โownerโ and set the value template to
{{ experience.user.id }}.
- Check the
Return tags as an object map instead of an arraycheckbox. This changes how tags are returned. It makes them an object map, which is easier to work with in most cases.
- Set the
Result Pathto
data.devices.
In Part 3 of this walkthrough, we showed how devices were tagged with the owner when they were created. We can now use this tag to find all devices owned by the user that requested this endpoint. Losant automatically adds the Experience User to the payload whenever an authenticated route is requested, so we can get the user ID at
experience.user.id.
All thatโs left to do for this endpoint is to reply with the devices we just looked up.
- Set the
Response Code Templateto
200, which is the HTTP status code for OK.
- Change the
Response Body Sourceradio to
Payload Path.
- Change the
Response Body Payload Pathto
data.devices. This is the location on the payload where the Get Device node put its result. Weโre going to simply reply with the same value.
- Add a
Content-Typeheader with the value
application/json.
At this point, the lลm mobile app can now request all of the devices owned by the currently logged-in user. You can test this route by requesting the devices created in Part 3 of this walkthrough.
curl -H "Authorization: Bearer USER_TOKEN" \
[ { "name": "My Awesome Plant", "tags": { "owner": [ "58e016591c3ce300017cc5d4" ], "manufacturerId": [ "000000" ] }, "attributes": [ { "name": "moisture", "dataType": "number" } ], "id": "58e4605f29eeec0001d383df" ... } ]
The lลm mobile app now allows the user to select a device from the list to show historical moisture data collected by that device. In order to support this, we need to create a new endpoint to get this data. Weโll call it
GET /devices/{id}/data. The device ID for each device is available on the result of the
GET /devices endpoint above.
- Set the
Methodto
GET.
- Set the
Routeto
/devices/{id}/data. This route makes use of route parameters, which provide a way to pass variables to the endpoint. In this case, weโll be passing the Losant device ID.
- Set the
Access Controlto
Any authenticated user.
Next, create a workflow for this endpoint with a matching endpoint trigger. The first thing this workflow needs to do once itโs triggered is to determine whether or not the current user has access to the device ID that was passed in. We can do this by getting the device that matches the route parameter and then checking that its owner tag matches the ID of the current user.
First, add a get device node to the canvas.
- Set the
ID Templateto
{{ data.params.id }}.
- Check the
Return tags as an object map instead of an arraycheckbox.
- Set the
Result Pathto
data.device.
Losant automatically parses the route parameters and put them on the payload. In this case, our device ID parameter
id can be found at
data.params.id.
The next step is to add a Conditional node to check that this device has an owner tag that matches the current user.
Set the
Expression to the following:
{{ data.device }} && {{ data.device.tags.owner.[0] }} === {{ experience.user.id }}
This expression first checks to see if any device was returned at all. Since this route could be requested with any value as the ID, for example
/devices/not-a-real-value/data, the result of the Get Device node could be
null. It then checks that the value of the owner tag matches the current Experience User. Since Losant devices can have duplicate values for the same tag, the values are always returned as an array, which is why the syntax is
data.device.tags.owner.[0].
If the device canโt be found, or the owner tag doesnโt match, simply use an Endpoint Reply node to respond with a 403 (Forbidden).
If we did get a valid device ID, we can now use the Time Series node to request historical data for the device.
- Select the
Use Device ID(s) specified on the current payloadradio.
- Set the
Device ID(s) JSON Pathto
data.params.id. This will perform a time series query against the device that was passed in through the route parameters.
- Set the
Time Rangeto whatever range makes sense for the application. In this example, itโs showing the last 24 hours of data.
- Set the
Resolutionto whatever makes sense for the application. In this example, it will return 24 hours of data with a data point for each 5 minute interval.
- Set the
Payload Path for Valueto
data.resultData.
The Time Series node provides powerful aggregation support for data that has been reported by your devices. The duration, resolution, and aggregation can all be changed to match your desired result. The last step is to reply with this data using an Endpoint Reply node.
- Set the
Response Code Templateto
200, which is the HTTP status code for
OK.
- Change the
Response Body Sourceradio to
Payload Path.
- Set the
Response Body Payload Pathto
data.resultData. This where the Time Series node put its result, so this reply is simply sending the result back to the client.
- Add a
Content-Typeheader with the value
application/json.
You can now test this endpoint to see data that has been reported by your applicationโs devices.
curl -H "Authorization: Bearer USER_TOKEN" \
[ { "time": "2017-04-05T05:05:00.000Z", "sum": 235, "count": 5, "value": 47 }, { "time": "2017-04-05T05:00:00.000Z", "sum": 235, "count": 5, "value": 47 } ... ]
The result of this API request will be a data point for each five-minute interval over the last 24 hours. Since the aggregation in the Time Series node was set to
Mean, the
value above will be the average. The
count is the number of data points collected in that five-minute interval. The
sum is the value of every point collected in the five-minute interval added together.
The lลm mobile app now has an API that supports all required features. Users can sign up, they can log in, they can register devices, they can see a list of their devices, and they can view historical data for each device. This concludes the Losant Application Experience walkthrough. If you have additional questions about experiences, please visit our forums.

Advanced scheduling involves configuring a pod so that the pod is required to run on particular nodes or has a preference to run on particular nodes.
Generally, advanced scheduling is not necessary, as the OpenShift Container Platform automatically places pods in a reasonable manner. For example, the default scheduler attempts to distribute pods across the nodes evenly and considers the available resources in a node. However, you might want more control over where a pod is placed.
If a pod needs to be on a machine with a faster disk speed (or prevented from being placed on that machine) or pods from two different services need to be located so they can communicate, you can use advanced scheduling to make that happen.
To ensure that appropriate new pods are scheduled on a dedicated group of nodes and prevent other new pods from being scheduled on those nodes, you can combine these methods as needed.
There are several ways to invoke advanced scheduling in your cluster:
Pod affinity allows a pod to specify an affinity (or anti-affinity) towards a group of pods (for an applicationโs latency requirements, due to security, and so forth) it can be placed with. The node does not have control over the placement.
Pod affinity uses labels on nodes and label selectors on pods to create rules for pod placement. Rules can be mandatory (required) or best-effort (preferred).
Node affinity allows a pod to specify an affinity (or anti-affinity) towards a group of nodes (due to their special hardware, location, requirements for high availability, and so forth) it can be placed on. The node does not have control over the placement.
Node affinity uses labels on nodes and label selectors on pods to create rules for pod placement. Rules can be mandatory (required) or best-effort (preferred).
See Using Node Affinity.
Node selectors are the simplest form of advanced scheduling. Like node affinity, node selectors also use labels on nodes and label selectors on pods to allow a pod to control the nodes on which it can be placed. However, node selectors do not have required and preferred rules that node affinities have.
See Using Node Selectors.
Taints/Tolerations allow the node to control which pods should (or should not) be scheduled on them. Taints are labels on a node and tolerations are labels on a pod. The labels on the pod must match (or tolerate) the label (taint) on the node in order to be scheduled.
Taints/tolerations have one advantage over affinities. For example, if you add to a cluster a new group of nodes with different labels, you would need to update affinities on each of the pods you want to access the node and on any other pods you do not want to use the new nodes. With taints/tolerations, you would only need to update those pods that are required to land on those new nodes, because other pods would be repelled. | https://docs.openshift.com/container-platform/3.6/admin_guide/scheduling/scheduler-advanced.html | 2019-07-15T20:21:05 | CC-MAIN-2019-30 | 1563195524111.50 | [] | docs.openshift.com |

Toctree and the Hierarchical Structure of a Manual ยถ
You can define what should be included in the menu with the
.. toctree::
directive.
Only
.rst
files that are included in a toctree, are included in the menu.
The toctree directive can also be used to display a table of contents on current page (if :hidden: is not added in toctree).
The first headline of an .rst file is its โdoctitleโ. That is the documentโs title property. The title and the following headlines are used for cross-references and appear in menus and table of contents.
General Rules for Using
..toctree::
ยถ
Each .rst file should have a doctitle, for example:
========== Some Title ==========
Do not use any additional headlines in the file if it contains a
.. toctree::directive.
Note: What we call โheadlinesโ here is called โsectionsโ in reST-jargon, see Headlines and Sections .
How it works ยถ
2017-02-13 by Martin Bless
TYPO3 documentation usually starts with the file
PROJECT/Documentation/Index.rst
.
The text may go into more than one textfile and these can be โpulled inโ and
referenced by the
.. toctree::
directive. Note:
- Each
.. toctree::directive creates a sublevel of headlines in the menu.
- The sublevel refers to the current level .
- Problem
Sometimes you donโt get what you expect:
================ My Documentation ================ Introduction ============ This project does something very useful ... See the individual chapters. .. toctree:: Chapter-1 Chapter-2 Chapter-3
The example feels very natural. We are thinking of the introduction followed by the single chapters. Unfortunately we get something different. The chapters will all be a subpart of Introduction and not at the same level. It is exactly what the Sphinx documentation states and there is no easy way to โtweakโ this behavior.
- Solution
Use these rules of thumb:
- All or nothing: Pull in all content of a given level via
toctreeor donโt use
toctreeat all.
- Or, in other words: Do not use a headline (โsectionโ) in a document before a
.. toctree::directive unless you really want to place the pulled in documents at a sublevel of that section .
Here is how we can fix the example: Move the introduction to an extra file and pull it in just like the others.
Fixed example:
================ My Documentation ================ You can have text here. But don't introduce headlines, if you want to have the pulled in files at the same level. .. toctree:: Introduction Chapter-1 Chapter-2 Chapter-3
Now the document titles (not shown here) of the files
Introduction.rst,
Chapter-1.rst,
Chapter-2and
Chapter-3will all be at the sublevel of
My Documentationin the menu. | https://docs.typo3.org/m/typo3/docs-how-to-document/master/en-us/WritingReST/MenuHierarchy.html | 2019-07-15T20:58:20 | CC-MAIN-2019-30 | 1563195524111.50 | [] | docs.typo3.org |
There are some situations with iOSAppleโs mobile operating system. More info
See in Glossary where your game can work perfectly in the Unity editor but then doesnโt work or maybe doesnโt even start on the actual device. The problems are often related to code or content quality. This section describes the most common scenarios.
There are a number of reasons why this may happen. Typical causes include:
This message typically appears on iOS devices when your application receives a NullReferenceException. There are two ways to figure out where the fault happened:
Unity includes software-based handling of the NullReferenceException. The AOT compiler includes quick checks for null references each time a method or variable is accessed on an object. This feature affects script performance, which is why it is enabled only for development buildsA development build includes debug symbols and enables the Profiler. More info
See in Glossary (enable the script debugging option in Build Settings dialog). If everything was done right and the fault actually is occurring in .NET code then you wonโt see EXC_BAD_ACCESS anymore. Instead, the .NET exception text will be printed in the Xcode console (or else your code will just handle it in a โcatchโ statement). Typical output might be:
Unhandled Exception: System.NullReferenceException: A null value was found where an object instance was required. at DayController+$handleTimeOfDay$121+$.MoveNext () [0x0035a] in DayController.js:122
This indicates that the fault happened in the handleTimeOfDay method of the DayController class, which works as a coroutine. Also, if it is script code then you will generally be told the exact line number (e.g. โDayController.js:122โ). The offending line might be something like the following:
Instantiate(_img);
This might happen if, say, the script accesses an asset bundle without first checking that it was downloaded correctly.
Native stack traces are a much more powerful tool for fault investigation but using them requires some expertise. Also, you generally canโt continue after these native (hardware memory access) faults happen. To get a native stack trace, type bt all into the Xcode Debugger Console. Carefully inspect the printed stack traces; they may contain hints about where the error occurred. You might see something like:
... Thread 1 (thread 11523): 1. 0 0x006267d0 in m_OptionsMenu_Start () 1. 1 0x002e4160 in wrapper_runtime_invoke_object_runtime_invoke_void__this___object_intptr_intptr_intptr () 1. 2 0x00a1dd64 in mono_jit_runtime_invoke (method=0x18b63bc, obj=0x5d10cb0, params=0x0, exc=0x2fffdd34) at /Users/mantasp/work/unity/unity-mono/External/Mono/mono/mono/mini/mini.c:4487 1. 3 0x0088481c in MonoBehaviour::InvokeMethodOrCoroutineChecked () ...
Firstly, you should find the stack trace for โThread 1โ, which is the main thread. The very first lines of the stack trace will point to the place where the error occurred. In this example, the trace indicates that the NullReferenceException happened inside the OptionsMenu scriptโs Start method. Looking carefully at this method implementation would reveal the cause of the problem. Typically, NullReferenceExceptions happen inside the Start method when incorrect assumptions are made about initialization order. In some cases only a partial stack trace is seen on the Debugger Console:
Thread 1 (thread 11523): 1. 0 0x0062564c in start ()
This indicates that native symbols were stripped during the Release build of the application. The full stack trace can be obtained with the following procedure:
This usually happens when an external library is compiled with the ARM Thumb instruction set. Currently, such libraries are not compatible with Unity. The problem can be solved easily by recompiling the library without Thumb instructions. You can do this for the libraryโs Xcode project with the following steps:
If the library source is not available you should ask the supplier for a non-thumb version of the library.
Sometimes, you might see a message like Program received signal: โ0โ. This warning message is often not fatal and merely indicates that iOS is low on memory and is asking applications to free up some memory. Typically, background processes like Mail will free some memory and your application can continue to run. However, if your application continues to use memory or ask for more, the OS will eventually start killing applications and yours could be one of them. Apple does not document what memory usage is safe, but empirical observations show that applications using less than 50% of all device RAM do not have major memory usage problems. The main metric you should rely on is how much RAM your application uses. Your application memory usage consists of three major components:
Note: The internal profiler shows only the heap allocated by .NET scriptsA piece of code that allows you to create your own Components, trigger game events, modify Component properties over time and respond to user input in any way you like. More info
See in Glossary. Total memory usage can be determined via Xcode Instruments as shown above. This figure includes parts of the application binary, some standard framework buffers, Unity engine internal state buffers, the .NET runtime heap (number printed by internal profiler), GLES driver heap and some other miscellaneous stuff.
The other tool displays all allocations made by your application and includes both native heap and managed heap statistics. The important statistic is the Net bytes value.
To keep memory usage low:
Querying the OS about the amount of free memory may seem like a good idea to evaluate how well your application is performing. However, the free memory statistic is likely to be unreliable since the OS uses a lot of dynamic buffers and caches. The only reliable approach is to keep track of memory consumption for your application and use that as the main metric. Pay attention to how the graphs from the tools described above change over time, especially after loading new levels.
There could be several reasons for this. You need to inspect the device logs to get more details. Connect the device to your Mac, launch Xcode and select Window > Devices and Simulators from the menu. Select your device in the windowโs left toolbar, then click on the Show the device console button and review the latest messages carefully. Additionally, you may need to investigate crash reports. You can find out how to obtain crash reports here:.
There is a poorly-documented time limit for an iOS application to render its first frames and process input. If your application exceeds this limit, it will be killed by SpringBoard. This may happen in an application with a first sceneA Scene contains the environments and menus of your game. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info
See in Glossary which is too large, for example. To avoid this problem, it is advisable to create a small initial scene which just displays a splash screen, waits a frame or two with yield and then starts loading the real scene. This can be done with code as simple as the following:
IEnumerator Start() { yield return new WaitForEndOfFrame(); // Do not forget using UnityEngine.SceneManagement directive SceneManager.LoadScene("Test"); }
Currently Type.GetProperty() and Type.GetValue() are supported only for the .NET 2.0 Subset profile. You can select the .NET API compatibility level in the Player settings.
Note: Type.GetProperty() and Type.GetValue() might be incompatible with managed code stripping and might need to be excluded (you can supply a custom non-strippable type list during the stripping process to accomplish this). For further details, see the iOS player size optimization guide.
The Mono .NET implementation for iOS is based on AOT (ahead of time compilation to native code) technology, which has its limitations. It compiles only those generic type methods (where a value type is used as a generic parameter) which are explicitly used by other code. When such methods are used only via reflection or from native code (i.e. the serialization system) then they get skipped during AOT compilationAhead of Time (AOT) compilation is an iOS optimization method for optimizing the size of the built iOS player More info
See in Glossary. The AOT compiler can be hinted to include code by adding a dummy method somewhere in the script code. This can refer to the missing methods and so get them compiled ahead of time.
void _unusedMethod() { var tmp = new SomeType<SomeValueType>(); }
Note: Value types are basic types, enums and structs.
.NET Cryptography services rely heavily on reflection and so are not compatible with managed code stripping since this involves static code analysis. Sometimes the easiest solution to the crashes is to exclude the whole System.Security.Crypography namespace from the stripping process.
The stripping process can be customized by adding a custom link.xml file to the Assets folder of your Unity project. This specifies which types and namespaces should be excluded from stripping. Further details can be found in the iOS player size optimization guide.
<linker> <assembly fullname="mscorlib"> <namespace fullname="System.Security.Cryptography" preserve="all"/> </assembly> </linker>
You should consider the above advice or try working around this problem by adding extra references to specific classes to your script code:
object obj = new MD5CryptoServiceProvider();
This error usually happens if you use lots of recursive generics. You can hint to the AOT compiler to allocate more trampolines of type 0, type 1 or type 2. Additional AOT compiler command line options can be specified in the Other Settings section of the Player settings. For for type 0 trampolines specify
ntrampolines=ABCD, where ABCD is the number of new trampolines required (i.e. 4096). For type 1 trampolines specify
nrgctx-trampolines=ABCD and for type 2 trampolines specify
nimt-trampolines=ABCD.
With some latest Xcode releases there were changes introduced in PNG compression and optimization tool. These changes might cause false positives in Unity iOS runtime checks for splash screen modifications. If you encounter such problems try upgrading Unity to the latest publicly available version. If this does not help, you might consider the following workaround:
If this still does not help try disabling PNG re-compression in Xcode:
The most common mistake is to assume that WWW downloads are always happening on a separate thread. On some platforms this might be true, but you should not take it for granted. Best way to track WWW status is either to use the yield statement or check status in Update method. You should not use busy while loops for that.
Some operations with the UI(User Interface) Allows a user to interact with your application. More info
See in Glossary will result in iOS redrawing the window immediately (the most common example is adding a UIView with a UIViewController to the main UIWindow). If you call a native function from a script, it will happen inside Unityโs PlayerLoop, resulting in PlayerLoop being called recursively. In such cases, you should consider using the performSelectorOnMainThread method with waitUntilDone set to false. It will inform iOS to schedule the operation to run between Unityโs PlayerLoop calls.
If your application runs ok in editor but you get errors in your iOS project this may be caused by missing DLLs (e.g. I18N.dll, I19N.West.dll). In this case, try copying those dlls from within the Unity.app to your projectโs Assets\Plugins folder. The location of the DLLs within the unity app is: Unity.app\Contents\Frameworks\Mono\lib\mono\unity You should then also check the stripping level of your project to ensure the classes in the DLLs arenโt being removed when the build is optimised. Refer to the iOS Optimisation Page for more information on iOS Stripping Levels.
Typically, such a message is received when the managed function delegate is passed to the native function, but the required wrapper code wasnโt generated when the application was built. You can help AOT compiler by hinting which methods will be passed as delegates to the native code. This can be done by adding the MonoPInvokeCallbackAttribute custom attribute. Currently, only static methods can be passed as delegates to the native code.
Sample code:
using UnityEngine; using System.Collections; using System; using System.Runtime.InteropServices; using AOT; public class NewBehaviourScript : MonoBehaviour { [DllImport ("__Internal")] private static extern void DoSomething (NoParamDelegate del1, StringParamDelegate del2); delegate void NoParamDelegate (); delegate void StringParamDelegate (string str); [MonoPInvokeCallback(typeof(NoParamDelegate))] public static void NoParamCallback() { Debug.Log ("Hello from NoParamCallback"); } [MonoPInvokeCallback(typeof(StringParamDelegate))] public static void StringParamCallback(string str) { Debug.Log(string.Format("Hello from StringParamCallback {0}", str)); } // Use this for initialization void Start() { DoSomething(NoParamCallback, StringParamCallback); } }
This error usually means there is just too much code in single module. Typically, it is caused by having lots of script code or having big external .NET assemblies included into build. And enabling script debugging might make things worse, because it adds quite few additional instructions to each function, so it is easier to hit that limit.
Enabling managed code stripping in Player settings might help with this problem, especially if big external .NET assemblies are involved. But if the issue persists then the best solution is to split user script code into multiple assemblies. The easiest way to this is move some code to Plugins folder. Code at this location is put to a different assembly. Also, check the information about how special folder names affect script compilation.

This page provides information on the Bump Normals Render Element which creates a normal-style image from the camera view from bumps and normals in the scene.
Overview
V-Ray Bump Normals is a render element that stores the camera view as a normal map. The normals are generated using screen space (the Screen coordinate system in Maya)RE_Normals) page.
This render element is similar to the Normals (vrayRE_Normals) Render Element that does not include bump maps.
The Bump Normal Render Element is useful for adjusting lighting that comes from a particular direction. For example, faces of objects pointing toward the camera will be predominantly blue in vrayRE_BumpNormals, so the lighting on such objects can be adjusted by using the blue channel in compositing software.

Introduction
Stein Expedite helps you
- display data from Google Sheets on your website, using handlebars-like
{{ }}syntax
- directly link a form to a Google Sheet.
All straight through the simple, beloved HTML.
Expedite is a part of the Stein suite, and is thus powered by the Stein API. To utilize Expedite, though, you don't need to learn the details of the core API.
First, create an API for your sheet via the interface. It's nothing technical, and wouldn't take you more than a couple of minutes.
Read on to learn how to install Expedite on your site. | https://docs.steinhq.com/expedite-introduction | 2019-07-15T20:55:29 | CC-MAIN-2019-30 | 1563195524111.50 | [] | docs.steinhq.com |
Hevo sends out alerts to its users for any changes that occur on pipelines, models, workflows, and destinations. Hevo also sends out a periodic status update on the above entities. These alerts are delivered to users over email or Slack.
As a User, at times you might want to receive alerts over Slack only but not over email or vice-versa. It is also possible that you might want to completely opt out of certain kinds of notifications completely. Hevo allows you to set up alert preferences as per your need.
To customize your alerts preferences, select the Admin tab on the left bottom of the screen and click on Settings. In the screen that opens up, select Alerts on the top bar and then head on to the Preferences tab on the sidebar.
Select the check boxes for the alerts you want to receive, under the channel you want to receive it on. Once you are done with the selection, click on save preference. You will now receive alerts only according to the set preference.

Opening a Device
Before using a device, you must initialize it by using the open (MCI_OPEN) command. This command loads the driver into memory (if it isn't already loaded) and retrieves the device identifier you will use to identify the device in subsequent MCI commands. You should check the return value of the mciSendString or mciSendCommand function before using a new device identifier to ensure that the identifier is valid. (You can also retrieve a device identifier by using the mciGetDeviceID function.)
Like all MCI command messages, MCI_OPEN has an associated structure. These structures are sometimes called parameter blocks. The default structure for MCI_OPEN is MCI_OPEN_PARMS. Certain devices (such as waveform and overlay) have extended structures (such as MCI_WAVE_OPEN_PARMS and MCI_OVLY_OPEN_PARMS) to accommodate additional optional parameters. Unless you need to use these additional parameters, you can use the MCI_OPEN_PARMS structure with any MCI device.
The number of devices you can have open is limited only by the amount of available memory.
Using an Alias
When you open a device, you can use the "alias" flag to specify a device identifier for the device. This flag lets you assign a short device identifier for compound devices with lengthy filenames, and it lets you open multiple instances of the same file or device.
For example, the following command assigns the device identifier "birdcall" to the lengthy filename C:\NABIRDS\SOUNDS\MOCKMTNG.WAV:
mciSendString( "open c:\nabirds\sounds\mockmtng.wav type waveaudio alias birdcall", lpszReturnString, lstrlen(lpszReturnString), NULL);
In the command-message interface, you specify an alias by using the lpstrAlias member of the MCI_OPEN_PARMS structure.
Specifying a Device Type
When you open a device, you can use the "type" flag to refer to a device type, rather than to a specific device driver. The following example opens the waveform-audio file C:\WINDOWS\CHIMES.WAV (using the "type" flag to specify the waveaudio device type) and assigns the alias "chimes":
mciSendString( "open c:\windows\chimes.wav type waveaudio alias chimes", lpszReturnString, lstrlen(lpszReturnString), NULL);
In the command-message interface, the functionality of the "type" flag is supplied by the lpstrDeviceType member of the MCI_OPEN_PARMS structure.
Simple and Compound Devices
MCI classifies device drivers as compound or simple. Drivers for compound devices require the name of a data file for playback; drivers for simple devices do not.
Simple devices include cdaudio and videodisc devices. There are two ways to open simple devices:
Specify a pointer to a null-terminated string containing the device name from the registry or the SYSTEM.INI file.
For example, you can open a videodisc device by using the following command:
mciSendString("open videodisc", lpszReturnString, lstrlen(lpszReturnString), NULL);
In this case, "videodisc" is the device name from the registry or the [mci] section of SYSTEM.INI.
- Specify the actual name of the device driver. Opening a device using the device-driver filename, however, makes the application device-specific and can prevent the application from running if the system configuration changes. If you use a filename, you do not need to specify the complete path or the filename extension; MCI assumes drivers are located in a system directory and have the .DRV filename extension.
Compound devices include waveaudio and sequencer devices. The data for a compound device is sometimes called a device element. This document, however, generally refers to this data as a file, even though in some cases the data might not be stored as a file.
There are three ways to open a compound device:
- Specify only the device name. This lets you open a compound device without associating a filename. Most compound devices process only the capability (MCI_GETDEVCAPS) and close (MCI_CLOSE) commands when they are opened this way.
- Specify only the filename. The device name is determined from the associations in the registry.
- Specify the filename and the device name. MCI ignores the entries in the registry and opens the specified device name.
To associate a data file with a particular device, you can specify the filename and device name. For example, the following command opens the waveaudio device with the filename MYVOICE.SND:
mciSendString("open myvoice.snd type waveaudio", lpszReturnString, lstrlen(lpszReturnString), NULL);
In the command-string interface, you can also abbreviate the device name specification by using the alternative exclamation-point format, as documented with the open command.
Opening a Device Using the Filename Extension
If the open (MCI_OPEN) command specifies only the filename, MCI uses the filename extension to select the appropriate device from the list in the registry or the [mci extensions] section of the SYSTEM.INI file. The entries in the [mci extensions] section use the following form:
filename_extension = device_name
MCI implicitly uses device_name if the extension is found and if a device name has not been specified in the open command.
The following example shows a typical [mci extensions] section:
[mci extensions] wav=waveaudio mid=sequencer rmi=sequencer
Using these definitions, MCI opens the waveaudio device if the following command is issued:
mciSendString("open train.wav", lpszReturnString, lstrlen(lpszReturnString), NULL);
New Data Files
To create a new data file, simply specify a blank filename. MCI does not save a new file until you save it by using the save (MCI_SAVE) command. When creating a new file, you must include a device alias with the open (MCI_OPEN) command.
The following example opens a new waveaudio file, starts and stops recording, then saves and closes the file:
mciSendString("open new type waveaudio alias capture", lpszReturnString, lstrlen(lpszReturnString), NULL); mciSendString("record capture", lpszReturnString, lstrlen(lpszReturnString), NULL); mciSendString("stop capture", lpszReturnString, lstrlen(lpszReturnString), NULL); mciSendString("save capture orca.wav", lpszReturnString, lstrlen(lpszReturnString), NULL); mciSendString("close capture", lpszReturnString, lstrlen(lpszReturnString), NULL);
Sharable Devices
The "sharable" (MCI_OPEN_SHAREABLE) flag of the open (MCI_OPEN) command lets multiple applications access the same device (or file) and device instance simultaneously. If your application opens a device or file as sharable, other applications can also access it by opening it as sharable. The shared device or file gives each application the ability to change the parameters governing its operating state. Each time a device or file is opened as sharable, MCI returns a unique device identifier, even though the identifiers refer to the same instance.
If your application opens a device or file without specifying that it is sharable, no other application can access it until your application closes it. Also, if a device supports only one open instance, the open command will fail if you specify the sharable flag.
If your application opens a device and specifies that it is sharable, your application should not make any assumptions about the state of this device. Your application might need to compensate for changes made by other applications accessing the device.
Most compound files are not sharable; however, you can open multiple files, or you can open a single file multiple times. If you open a single file multiple times, MCI creates an independent instance for each, with each instance having a unique operating status.
If you open multiple instances of a file, you must assign a unique device identifier to each. You can use an alias, as described in the following section, to assign a unique name for each file. | https://docs.microsoft.com/en-us/windows/win32/multimedia/opening-a-device | 2019-07-15T21:40:51 | CC-MAIN-2019-30 | 1563195524111.50 | [] | docs.microsoft.com |

CURRENT_TIMESTAMP โ Returns the current time as a timestamp value.
CURRENT_TIMESTAMP
The CURRENT_TIMESTAMP function returns the current time as a VoltDB timestamp. The value of the timestamp is determined when the query or stored procedure is invoked. Several important aspects of how the CURRENT_TIMESTAMP function operates are:
The value returned is guaranteed to be identical for all partitions that execute the query.
The value returned is measured in milliseconds then padded to create a timestamp value in microseconds.
During command logging, the returned value is stored as part of the log, so when the command log is replayed, the same value is used during the replay of the query.
Similarly, for database replication (DR) the value returned is passed and reused by the replica database when replaying the query.
You can specify CURRENT_TIMESTAMP as a default value in the CREATE TABLE statement when defining the schema of a VoltDB database.
The CURRENT_TIMESTAMP function cannot be used in the CREATE INDEX or CREATE VIEW statements.
The NOW and CURRENT_TIMESTAMP functions are synonyms and perform an identical function. | https://docs.voltdb.com/UsingVoltDB/sqlfunccurrenttimestamp.php | 2015-10-04T12:42:38 | CC-MAIN-2015-40 | 1443736673632.3 | [] | docs.voltdb.com |

Main talk file other
From Joomla! Documentation
other
This template is used inside other templates that need to behave differently (usually look differently) depending on what type of page they are on. It detects and groups all the different namespaces used on Joomla! Documentation into four types:
- main = Main/article space, as in normal Wikipedia articles.
- talk = Any talk space, such as page names that start with "Talk:", ":", "Framework talk:" and so on.
- file = Image/media space, such as viewing an uploaded file
- other = All other spaces, such as page names that start with "User:", ":", "Framework:" and so on.
Functions/Features
If this template is used without any parameters it returns the type name that the page belongs to: main, talk, file or other.
This template can also take four parameters and then returns one of them depending on which type a page belongs to.
Usage:
- Other pages text
Parameters

Search and indexing
Orchard provides the ability to index and search content items in the application. The indexing functionality is provided by enabling the Indexing feature, along with a specific implementation of indexing (Lucene-based is included by default). In addition to the Indexing, the Search feature provides the ability to query the index (by keyword or using Lucene query syntax) to return a list of content items matching the query on the front end.
You must enable all the following Modules Search, Indexing, and Lucene.
Because search depends on indexing, enabling search will automatically enable indexing as well. Note that you must also enable Lucene before search and indexing will work.
When the indexing feature is enabled, a new Search and Indexes item becomes available under the Settings section of the dashboard. The indexer runs as a background task, once per minute by default, and you can optionally update or rebuild the index from this screen. The Indexes screen also displays the number of documents (content items) indexed and the Search screen displays the indexed fields.
After enabling the Search feature goto the Content Definition section and click on any Content Type which you want to index and then check the check box for the available index. For e.g. Page Content Type
When the search feature is enabled, the Settings screen in the dashboard displays the fields that will be queried from the index (listed on the Search screen).
The front end of the site does not have the searching UI yet at this point. To add it, you need to add a widget. Click Widgets in the admin menu. With the default layer selected, click Add to zone next to SearchForm in the list of available widgets.
Keep "Header" selected as the zone and "Default" as the layer so that your search widget appears on top of all pages (the default layer applies to all pages in the site).
Give it a title such as "Search" and click the Save button.
For more information about widgets, see Managing widgets.
If you navigate now to any page in the front end of the site, you will see the search form.
When you type a keyword or query into this input box, a list of matching content items is displayed.

Introduction
Many stablecoin protocols have entirely embraced one spectrum of design (entirely collateralized) or the other extreme (entirely algorithmic with no backing). Collatralized stablecoins either have custodial risk or require on-chain over-collateralization. These designs provide a stablecoin with a fairly tight peg with higher confidence than purely algorithmic designs. Purely algorithmic designs such as Basis, Empty Set Dollar, and Seigniorage Shares provide a highly trustless and scalable model that captures the early Bitcoin vision of decentralized money but with useful stability. The issue with algorithmic designs is that they are difficult to bootstrap, slow to grow (as of Q4 2020 none have significant traction), and exhibit extreme periods of volatility which erodes confidence in their usefulness as actual stablecoins. They are mainly seen as a game/experiment than a serious alternative to collateralized stablecoins. XUSD attempts to be the stablecoin protocol to implement design principles of both to create a highly scalable, trustless, extremely stable, and ideologically pure on-chain money. The XUSD protocol is a two token system encompassing a stablecoin, XUSD (XUSD), and a governance token, XUSD Shares (XUS). The protocol also has pool contracts that hold collateral (at genesis WETH and DAI). Pools can be added or removed with governance. Although there are no predetermined timeframes for how quickly the number of collateralization changes, we believe that as XUSD adoption increases, users will be more comfortable with a higher percentage of XUSD supply being stabilized algorithmically rather than with collateral. The collateral ratio refresh function in the protocol can be called by any user once per hour. The function can change the collateral ratio in steps of .25% if the price of XUSD is above or below $1. When XUSD is above $1, the function lowers the collateral ratio by one step and when the price of XUSD is below $1, the function increases the collateral ratio by one step. Both refresh rate and step parameters can be adjusted through governance. In a future update of the protocol, they can even be adjusted dynamically using a PID controller design. The price of XUSD, XUS, and collateral are all calculated with a time-weighted average of the Uniswap pair price and the ETH:USD Chainlink oracle. The Chainlink oracle allows the protocol to get the true price of USD instead of an average of stablecoin pools on Uniswap. This allows XUSD to stay stable against the dollar itself which would provide greater resiliency instead of using a weighted average of existing stablecoins only.
XUSD stablecoins can be minted by placing the appropriate amount of its constituent parts into the system. At genesis, XUSD is 100% collateralized, meaning that minting XUSD only requires placing collateral into the minting contract. During the fractional phase, minting XUSD requires placing the appropriate ratio of collateral and burning the ratio of XUSD Shares (XUS). While the protocol is designed to accept any type of cryptocurrency as collateral, this implementation of the XUSD Protocol will mainly accept on-chain stablecoins as collateral to smoothen out volatility in the collateral so that XUSD can transition to more algorithmic ratios smoothly.

A cryptocurrency system can be thought of as a payments and financial infrastructure that is not controlled by any single entity, such as a bank, company, or government. Prior to the introduction of cryptocurrencies, there had always been an operator that had control of transaction inclusion and monetary policy. This operator represented a centralized point of both power and failure.
The financial world was fundamentally changed with the introduction of Bitcoin on January 3, 2009. In the years that have followed, many other cryptocurrencies have been created to solve various problems in the legacy financial realm.
Cryptocurrencies use clever cryptography, mathematics, and monetary incentives to create a system where people called farmers or miners get paid to run the system, and there is no central point of control that can be taken down by malicious actors.
This brings many benefits, some of which are:
- No requirements to participate: Anyone with an internet connection can participate in the new crypto economy, regardless of nationality, wealth status, religion, etc.
- Censorship resistance: Censorship is difficult or impossible. Anyone is allowed to transact, and to send any amount or run any program at any time.
- Independent monetary policy: New currencies can be created that do not depend on decisions made by one group or one country, and instead can be based on algorithms or have a fixed supply.
- Unstoppable applications: A program developed for, and run on, a secure blockchain can never be changed or stopped. The program itself can own funds and perform financial transactions. Code can run autonomously, without depending on a human operator. Some blockchain applications include: tokenization of other assets, non-fungible tokens (NFTs), loans, remittances, identity wallets, etc.
- Global standards: Through crypto, different countries and regions can interact and transact on one shared standard that is clearly documented, fully open source, and available for free. Different parties can come together to use a neutral platform, which reduces costs for those who build on top of the cryptocurrency.
- Security: There are many forms of potential attacks on any financial infrastructure, including virtual and physical hacks, bribery, network issues, etc. A system with a million nodes is much more difficult to attack than the aforementioned single point of failure.

To understand the basics of how a cryptocurrency like Bitcoin or Chia works, we first need to look at how one would design a cryptocurrency from scratch. This section is targeted toward those new to the blockchain industry; others can skip it.
We could rely on a central server with a public API to send transactions (which takes in a username and password) and a public API for reading data. However, this is not decentralized, and it does not bring most of the benefits above. This is the way in which many financial systems worked before Bitcoin.
How would we design a transaction system which does not depend on any one party?

First, we need a secure way to send transactions to many servers. Let's assume that there are 1000 servers across the world, instead of just one, and that these servers send transaction information of users to each other.
These servers are assumed to be run by different entities (companies, people, etc). Usernames and passwords would not work in this decentralized model, because every server would need to know the password in order to verify that a transaction is valid. This would be extremely insecure.
Instead, we can use public key cryptography, invented by Hellman, Merkle, and Diffie.
For example, a user named Alice maintains a secret key (also called a private key)
sk_a, and a public key
pk_a. The public key is posted in a transaction next to her balance, let's say 1 BTC. In order to spend that 1 BTC, she needs to provide a digital signature with her private key. The signature can be verified with the public key and message only, and is specific to the data that is being signed.
Each server running in this decentralized system can accept a transaction, which includes the ID of the coin that is being sent, the recipient information, and the signature.
Digital signatures are fundamental building blocks for cryptocurrencies.

However, signatures are not enough, because of an issue called the "double spend problem." Of the 1000 servers, let's say 500 are in Asia and 500 are in America. An attacker, Bob, sends two transactions that spend the same coin, to two servers, at the same time: one in Asia and one in America. Those transactions send the money to different recipients, which should not be allowed.
In this case, the two servers need to come to agreement as to which transaction came first. Otherwise, they will have diverging state, and the system will not have global consensus. To solve this issue, we need a consensus algorithm, or a way for all computers in the system to quickly come to unambiguous agreement on the ordering and content of transactions.
Since we are trying to create a globally decentralized and secure system, why not allow each person one vote, and add up votes for deciding transaction ordering? This would be great if it were possible, but it unfortunately requires some type of central party, first to decide who is a "person," and then to create these identities. This would make the system centralized.
We could instead base the system on "one computer, one vote," counting each IP address as a "computer." However, it is trivial to buy new IP addresses, or to change addresses using a VPN or a proxy server. An attacker could even create millions of fake IP addresses. The attacker would gain control of the network once they own 51% of the addresses. At this point, they could decide transaction ordering and content. Again, the system becomes centralized, and possibly compromised.
The key issue that makes it difficult to solve the double-spend problem is the Sybil attack. A Sybil attack is when an attacker creates a large amount of fake identities at a low cost. Most "Proof of X" blockchains are not secure because if an attacker creates multiple identities, this will give the attacker an advantage.
The genius of Satoshi Nakamoto was to solve the double-spend problem by requiring real-world work in order to obtain "votes," and to decide consensus. This "Proof of Work" is cryptographically verifiable. The only requirements for participation are a computer and an internet connection.
In Proof of Work networks, each computer that is participating repeatedly generates cryptographic hashes using random input. This functions as a global lottery, where hashes are generated until one computer generates a winner -- a hash with a certain number of leading zeros. This is known as a proof of work because there are no shortcuts. Computers must put in the required amount of computational "work" by generating hashes.
When a winning proof is found, the computer that discovered it earns the right to generate a new "block" in the blockchain. This block contains a pointer to the previous block, a list of valid transactions, and the winning hash. All nodes are required to accept the heaviest chain (the one which required the most work). Therefore, all nodes will accept the new block, and the proof-of-work lottery begins anew.
In Bitcoin's consensus algorithm, each proof takes an average of 10 minutes to generate. As more computers join the network, the average amount of time to generate a proof will naturally decrease. This brings us to another of Satoshi's simple and elegant ideas: the difficulty adjustment. Every 2016 blocks (two weeks, on average) the proof-of-work algorithm automatically adjusts how difficult it is to find a proof. It accomplishes this by increasing or decreasing the required number of leading zeros in a generated hash. The result is that the average time required to find a proof will always be 10 minutes, no matter how many computers start or stop participating in the proof-of-work lottery.
With this consensus mechanism in place, attacking the network becomes very difficult. If an attacker wants to "rewrite history" by creating an alternative blockchain, they'll need to create new blocks faster than the honest actors in the system. Because of the proof of work that is required to create each block, the attacker will need to generate hashes faster than all other computers in the network, combined. This is known as a "51% attack" and is discussed in greater detail later Section 3.14.
Proof of Work solves the double-spend problem -- only one computer can create a block at any one time. It also solves the Sybil problem -- not only does creating a block require a real-world investment in hardware, but it also gives no advantage to someone who creates multiple identities. This person has the same probability of winning, whether they're using one identity or a million.

Each node in the network maintains active connections with a few other random nodes. If a user wants to make a transaction, they send it to any node in the network, which automatically broadcasts it to their peers. Because each node is connected to a unique set of peers, the transaction quickly gets propagated to every node in the network. The nodes then save the transaction, including all other pending transactions, locally in memory. This is called the mempool.
For more info on Chia's mempool, see Section 6.
In order for each node to search for a proof, it must assemble a block to hash against. It does this by including transactions from the mempool, and it will most likely choose the pending transactions that pay the highest fee. A transaction fee market is thus created, where the supply is the total transactions per second (TPS) that the system supports, and the demand is based on the number of transactions in the mempool. A transaction is said to be "confirmed" once it is included inside a block which has the required proof of work.
Blockchain transactions can also include scripts or programs, which allow controlling funds directly with code. This code can require a certain number of signatures to release the funds, or have any arbitrary logic.
Keep in mind that blockchain programs are expensive to run, since every node in the system must download and run the program. Just because it can be run on a blockchain, doesn't mean that is should be run on one.
Each block also has a hash pointer to the previous block. This means that the hash of the contents of the previous block are included in the current block. If an attacker could find an alternative valid proof for a historical block, the proof would then change that block's hash, which would invalidate the next block. If the attacker wanted to change a block that occurred 10 blocks in the past, they would therefore need to re-do the proof of work for at least 10 blocks. The rest of the network would continue to create legitimate blocks, however, so in reality, the attacker would likely have to create many more than just 10 blocks. In fact, as long as the rest of the network, combined, could create blocks at the same rate or faster, the attacker would never be able to create a chain longer than the legitimate chain.
The Bitcoin network performs around 170 quintillion (170,000,000,000,000,000,000) hashes per second; the attacker would have to control at least that much hashpower to make a 51% attack feasible.

Over a decade has passed since the creation of Bitcoin and Proof of Work blockchains. While Proof of Work is quite secure, that security comes at a cost: a tremendous expenditure of energy is required to generate those 170 quintillion hashes per second. On top of that, specialized hardware is required to run nodes on these systems, which has led to a high degree of centralization among the top miners.
Perhaps most troubling of all are the pools. On a given day, the hashrate of the top four or five Bitcoin pools constitutes over half of the overall hashrate. Arguably, the easiest attack against the Bitcoin network would be for the pool operators to collude (either willingly or under threat), putting a 51% attack well within reach.
These issues have prompted people to develop alternative Sybil-resistant consensus models. Proof of Stake (voting with blockchain assets) is one of the most popular approaches, and within this category there are many types of algorithms. These systems tend to compromise on decentralization (and thus, security) to varying degrees.
Chia takes an alternate approach called Proofs of Space and Time (PoST), which we think is likely to be more decentralized and accessible than Proof of Stake. In this model, full nodes store files full of millions of hashes (akin to lottery tickets, as described above) on hard drives. This model maintains the security properties of Nakamoto's Proof of Work, while remaining accessible to normal users without any special hardware. | https://chiadocs.chiabee.net/docs/01introduction/intro-to-cryptocurrencies/ | 2022-09-25T07:26:28 | CC-MAIN-2022-40 | 1664030334515.14 | [array(['/assets/images/crypto01-74539fda6967c7710c916ee3f75ff995.png',

Then, provide commonly used filter and search capabilities to let users narrow down the list.
Use a Record Type as the gridโs data source to take advantage of a search field and user filters that have already been defined in the Record Type object.
Record action buttons can be displayed in a grid column by using the Record Action component.
The pencil icon is a related action using the โIcon Onlyโ style
DON'T
Donโt display multiple related actions within a grid cell. Instead, try placing actions above the grid or in separate columns.
Record actions can be displayed in โToolbarโ style above a grid when the grid is backed by a Record Type. Selection is often necessary when related actions are configured. Refer to the Read-Only Grid documentation to learn more.
โNew Itemโ is a record list action and โEdit Caseโ and โReassign Caseโ are related actions
Establish an appropriate batch size that minimizes scrolling.
If the interface has several other components along with the grid, then use a smaller batch size, such as 5 - 10 items, so that the user can easily access the other components in the interface.
If the grid is the only component on the interface, prioritize getting the user to the items they are looking for on the first page using sort order and filter controls. Use a large batch size, such as 50 items, so that users can scroll to their items rather than paging multiple times and waiting for items to load.
If you are not sure if the sort order and filter controls will get the users to the items they are looking for on the first page, then use a smaller batch, size such as 25 items, and ensure that users are able to access paging controls without scrolling.
The first column should always be left aligned (in left-to-right languages) regardless of the value type. For all other columns, left align text columns and right align columns with numbers or dates.
For editable grid columns, use left alignment for all field types (in left-to-right languages) including numbers and dates.
Always align headers consistently with column content.
Use a hyphen (โ) when displaying cells with no value/data.
DO
DON'T
Avoid using โN/Aโ or โNot Applicableโ, as it tends to create clutter
Set column widths to โAutoโ (this is the default for new columns) to allow the grid to distribute space based on the amount of content in each column. When in doubt, try this setting first as it often produces good results without additional effort. Note that column widths will fluctuate as data changes: a cell with a large amount of text will cause its column to be wider, all else being equal.
Use fixed column widths, such as "Narrow" or "Wide", for consistent behavior that mimics how spreadsheets work. The width of each column will remain constant even as the width of the grid changes (such as when resizing the browser window). Horizontal scrolling will be automatically enabled when the total of column widths exceeds the gridโs width.
Note: when the total of configured column widths is less than the gridโs overall width, columns will be expanded to fill the available space.
Use relative widths to set proportional column widths that distribute available space. For example, 3 columns with "2X", "3X", and "5X" widths, respectively, will take up 20%, 30%, and 50% of the width of the grid. As much as possible, the proportional relationship between columns will be preserved as the overall grid width changes. A particular set of relative widths that look appropriate on a wide monitor, for example, may not work well on a phone display because each column will become much narrower.
A particular set of relative widths that work well on wide screens may not transfer well to narrow screens. The "Start Date" and "Department" column values on the phone are too narrow.
In general, relative column widths work well when the grid is typically viewed on similar screen sizes (i.e. mostly viewed on a phone or mostly viewed on a desktop monitor). Fixed column widths offer more predictability when grids are viewed across a wide variety of screen form factors.
Sometimes, the best results may come from using more than one type of grid column width configuration within the same grid. For example, one might set fixed widths for columns that always require the same amount of space: "Icon"-width for a column that shows a status icon, "Narrow"-width for a column that shows a percentage value. The remaining columns in the grid may show varying amounts of text and work best with "Auto" or a set proportion of relative widths.
While considerations for setting column widths are similar across the two types of grids, editable grids lack some of the configurations available for read-only grids.
Editable grids do not support automatic column widths based on the amount of content in each cell. The default column width of "Distribute" produces the same result as specifying "1" as the weight. A grid with all "Distribute"-width columns will evenly distribute space across all columns.
The editable grid (TOP) has "Distribute"-width columns, so the column spacing is evenly distributed. The read-only grid (BOTTOM) has "Auto"-width columns, allocating space based on the column content.
Editable grids only support "Icon" and "Narrow" fixed widths. Compared to read-only grids, less precision is possible when using fixed column widths and proportional weights may have to be relied upon in more cases. Remember that the same column weight may translate into a different width when a grid is viewed on different screen sizes.
The "Standard" grid spacing offers a good balance between information density and readability.
Use the "Dense" spacing option to reduce the need for vertical scrolling when showing grids with a large number of rows. Note that some users may find the dense grids to be harder to read because of their reduced white space.
Use the alternate row shading option to help users match up values on the same row when scanning grids with a lot of data. The shading may not be necessary when showing grids with only a few rows of data.
Use the "Light" border style to remove the outer border and vertical column divider lines from grids. This creates a less cluttered look for simple grids that can easily be scanned without the need for extra decorative lines.
DO
Use the "Row Highlight" selection style for read only content. An example of this can be seen in the grid with detail pattern.
DON'T
Avoid mixing "Row Highlight" selection style and interactive components, such as links or inputs, in grid cells. This may make it difficult for the user to differentiate between clicking on the row or one of the interactive components within the row. Instead, use the "Checkbox" selection style when there are interactive components in a grid.
When displaying multiple grids on the same page, use the same density and styling options for all grids to create a consistent experience.
Use the height option to maintain a fixed height for the grid regardless of the number of rows and to ensure that the header is always visible.
DON'T
Don't pick a fixed height when the grid is the only/main thing on the page as users may have to scroll the page AND scroll the contents of the grid to find what they're looking for
DON'T
Don't mix paging and fixed heights as users would have to scroll and page to find what they're looking for. At the same time, be aware of performance considerations when choosing to remove paging or setting a very large batch size and relying on scrolling.
When designing a grid, use the row header parameter to help screen reader users better understand the context of each cell theyโre traversing. The row header acts as the identifier for a given row, similar to how the column header is the identifier for each column. When users navigate to a cell within a grid, both the corresponding column header and row header values are announced by the screen reader.
Note that the row header is only recognized as the header for columns to its right. Because of this, the first column containing text is usually the correct choice for row header.

Period. The image below shows how the objectโs bounding box size is determined by the size of the object.
Relationship between an object and its bounding box.
In Object Mode
In Object Mode, transformation takes place relative to the location of the objects origin (indicated by the yellow circle), and the size of objects is not taken into account. The image below shows the results of using the Bounding Box as the pivot point in some situations.
In this example, the orange rectangle has its origin located on the far left of the mesh, while the blue rectangle has its origin located in the center of the mesh.
When a single object is selected, the rotation takes place around its origin.
Shows the location of the bounding box (right) pivot point compared to the median point (left).
The image above (left) shows that when multiple objects are selected, the pivot point is calculated based on the location of all the selected objects. More precisely, the centers of objects are taken into account.
In Edit Mode
This time it is the geometry that is enclosed in the bounding box. The bounding box in Edit Mode takes no account of the object(s) origins, only the center of the selected vertices.
The effects of rotation in different mesh selection modes when the bounding box is set as the pivot point. The pivot point is shown by a yellow circle.

RPM Packaging
This chapter deals with security-related concerns around RPM packaging. It has to be read in conjunction with distribution-specific packaging guidelines.
Generating X.509 Self-signed Certificates during Installation
Some applications need X.509 certificates for authentication purposes. For example, a single private/public key pair could be used to define cluster membership, enabling authentication and encryption of all intra-cluster communication. (Lack of certification from a CA matters less in such a context.) For such use, generating the key pair at package installation time when preparing system images for use in the cluster is reasonable. For other use cases, it is necessary to generate the key pair before the service is started for the first time, see Generating X.509 Self-signed Certificates before Service Start, and Packaging:Initial Service Setup.
In the spec file, we define two RPM variables which contain the names of the files used to store the private and public key, and the user name for the service:
# Name of the user owning the file with the private key %define tlsuser %{name} # Name of the directory which contains the key and certificate files %define tlsdir %{_sysconfdir}/%{name} %define tlskey %{tlsdir}/%{name}.key %define tlscert %{tlsdir}/%{name}.crt
These variables likely need adjustment based on the needs of the package.
Typically, the file with the private key needs to be owned by
the system user which needs to read it,
%{tlsuser} (not
root). In
order to avoid races, if the directory
%{tlsdir} is owned by the services
user, you should use the code in Creating a key pair in a user-owned directory.
The invocation of su with the
-s /bin/bash argument is necessary in case the
login shell for the user has been disabled.
%post if [ $1 -eq 1 ] ; then if ! test -e %{tlskey} ; then su -s /bin/bash \ -c "umask 077 && openssl genrsa -out %{tlskey} 2048 2>/dev/null" \ %{tlsuser} fi if ! test -e %{tlscert} ; then cn="Automatically generated certificate for the %{tlsuser} service" req_args="-key %{tlskey} -out %{tlscert} -days 7305 -subj \"/CN=$cn/\"" su -s /bin/bash \ -c "openssl req -new -x509 -extensions usr_cert $req_args" \ %{tlsuser} fi fi %files %dir %attr(0755,%{tlsuser},%{tlsuser]) %{tlsdir} %ghost %attr(0600,%{tlsuser},%{tlsuser}) %config(noreplace) %{tlskey} %ghost %attr(0644,%{tlsuser},%{tlsuser}) %config(noreplace) %{tlscert}
The files containing the key material are marked as ghost
configuration files. This ensures that they are tracked in the
RPM database as associated with the package, but RPM will not
create them when the package is installed and not verify their
contents (the
%ghost), or delete the files
when the package is uninstalled (the
%config(noreplace) part).
If the directory
%{tlsdir} is owned by
root, use the code in Creating a key pair in a
root-owned directory.
root-owned directory
%post if [ $1 -eq 1 ] ; then if ! test -e %{tlskey} ; then (umask 077 && openssl genrsa -out %{tlskey} 2048 2>/dev/null) chown %{tlsuser} %{tlskey} fi if ! test -e %{tlscert} ; then cn="Automatically generated certificate for the %{tlsuser} service" openssl req -new -x509 -extensions usr_cert \ -key %{tlskey} -out %{tlscert} -days 7305 -subj "/CN=$cn/" fi fi %files %dir %attr(0755,root,root]) %{tlsdir} %ghost %attr(0600,%{tlsuser},%{tlsuser}) %config(noreplace) %{tlskey} %ghost %attr(0644,root,root) %config(noreplace) %{tlscert}
In order for this to work, the package which generates the keys
must require the openssl package. If
the user which owns the key file is generated by a different
package, the package generating the certificate must specify a
Requires(pre): on the package which creates
the user. This ensures that the user account will exist when it
is needed for the su or
chmod invocation.
Generating X.509 Self-signed Certificates before Service Start
An alternative way to automatically provide an X.509 key pair is to create it just before the service is started for the first time. This ensures that installation images which are created from installed RPM packages receive different key material. Creating the key pair at package installation time (see Generating X.509 Self-signed Certificates during Installation) would put the key into the image, which may or may not make sense.
Generating key material before service start may happen very
early during boot, when the kernel randomness pool has not yet
been initialized. Currently, the only way to check for the
initialization is to look for the kernel message
random: nonblocking pool is initialized, or
ensure that the application used for generating the keys
is utilizing the
getrandom() system call.
In theory, it is also possible to use an application which reads from
/dev/random while generating the key
material (instead of
/dev/urandom), but
this can block not just during the boot process, but also much
later at run time, and generally results in a poor user
experience.
The requirements for generating such keys is documented at Packaging:Initial Service Setup. | https://docs.fedoraproject.org/es_419/defensive-coding/tasks/Tasks-Packaging/ | 2022-09-25T08:02:56 | CC-MAIN-2022-40 | 1664030334515.14 | [] | docs.fedoraproject.org |

Forewordยถ
From rsync Brief Description we know that rsync is an incremental synchronization tool. Every time the
rsync command is executed, data can be synchronized once, but data cannot be synchronized in real time. How to do it?
With inotify-tools, this program tool can realize one-way real-time synchronization. Since it is real-time data synchronization, the prerequisite is to log in without password authentication.
Regardless of whether it is rsync protocol or SSH protocol, both can achieve password-free authentication login.
SSH protocol password-free authentication loginยถ
First, generate a public key and private key pair on the client, and keep pressing Enter after typing the command. The key pair is saved in the /root/.ssh/ directory
[root@fedora ~]# ssh-keygen -t rsa -b 2048: TDA3tWeRhQIqzTORLaqy18nKnQOFNDhoAsNqRLo1TMg root@fedora The key's randomart image is: +---[RSA 2048]----+ |O+. +o+o. .+. | |BEo oo*....o. | |*o+o..*.. ..o | |.+..o. = o | |o o S | |. o | | o +. | |....=. | | .o.o. | +----[SHA256]-----+
Then, use the
scp command to upload the public key file to the server. For example, I upload this public key to the user testrsync
[root@fedora ~]# scp -P 22 /root/.ssh/id_rsa.pub [email protected]:/home/testrsync/
[root@Rocky ~]# cat /home/testrsync/id_rsa.pub >> /home/testrsync/.ssh/authorized_keys
Try to log in without secret authentication, success!
[root@fedora ~]# ssh -p 22 [email protected] Last login: Tue Nov 2 21:42:44 2021 from 192.168.100.5 [testrsync@Rocky ~]$
tip
The server configuration file /etc/ssh/sshd_config should be opened PubkeyAuthentication yes
rsync protocol password-free authentication loginยถ
On the client side, the rsync service prepares an environment variable for the system-RSYNC_PASSWORD, which is empty by default, as shown below:
[root@fedora ~]# echo "$RSYNC_PASSWORD" [root@fedora ~]#
If you want to achieve password-free authentication login, you only need to assign a value to this variable. The value assigned is the password previously set for the virtual user li. At the same time, declare this variable as a global variable.
[root@Rocky ~]# cat /etc/rsyncd_users.db li:13579
[root@fedora ~]# export RSYNC_PASSWORD=13579
Try it, success! No new files appear here, so the list of transferred files is not displayed.
[root@fedora ~]# rsync -avz [email protected]::share /root/ receiving incremental file list ./ sent 30 bytes received 193 bytes 148.67 bytes/sec total size is 883 speedup is 3.96
tip
You can write this variable into /etc/profile to make it take effect permanently. The content is:
export RSYNC_PASSWORD=13579

What is a database?ยถ
This may seem like a very simple question, but it can have different answers, depending on who you ask.
In order to avoid confusion, it is important to be aware of how different people might perceive this question.
If you were asked to provide a quote for creating a database, what kind of number would you provide?
Because I can think of many different numbers. I could create a database for $5.00. I could do it for $100. Or $10,000. Or $1 million.
In theory, you could launch a database management tool, create a new, empty database instance, and youโre done! You created a database. That will be $5.00 please.
That is usually not what people mean, though.
Typically when I discuss โdesigning a database,โ I am referring to the act of creating a database schema, which is primarily the tables and columns needed to store all data necessary for a specific project.
But people who are not database designers, or may not have any kind of technical expertise at all, may have very different perceptions of what a โdatabaseโ is.
They may expect a database to have data in it.
They may expect a database to have a comprehensive front-end.
They may think of a โdatabaseโ as being something like โIMDb.com,โ which has a sophisticated front end, fancy graphics, and a list of all possible movies, TV shows, and casts.
So before embarking on a database project, one needs to define what it is that will be included in the delivered โdatabaseโ?
What are all the project specifications?
What are all the available sample data files?
Will the database use explicit foreign keys or just implicit linking names?
Will data need to be loaded into the database?
Will there be human-friendly views for displaying database data?
Will the system need to have automated data-loading tools?
Will the system need to have tools for manually entering data?
Will the system need to have data-editing tools?
Will the system need a front end? What kind?
Anybody who is a project owner or project manager of an information system which includes a back-end database should be aware of how the simple word โdatabaseโ may signify different things to different people, including database designers.
Database designers and programmers who create databases should be aware that when they refer to a โdatabase,โ different people will have different perceptions of what this entails.
When to use NULLยถ
I previously wrote that optimal database design will avoid using columns that allow NULL. A database schema will be faster, easier to maintain, and easier to program for if you mostly avoid allowing NULL values.
But there ARE times when allowing a NULL value makes sense. Sometimes your column setting should be to โallow NULL.โ
The main reason for this is when you have a column whose value really does need to differentiate between null and a default value.
For text string columns (varchar), this is rarely the case. But for many other datatypes, this can make a difference.
Letโs consider numbers. If possible, I like to avoid using NULL for number columns as well. For example if I have inventory count column, I would prefer to use zero as a default and not allow null. This would mean that the system will display zero inventory for a product if the value is not known. Rather than allow null, the default for the column is set to zero.
But what if the system demands a distinction between โzero inventoryโ and โwe
donโt know the inventoryโ? Then there are two ways to handle this:
- We could set the inventory column to allow null
- Or we could use an additional boolean column to indicate that the inventory is unknown.
Both of these are valid options. But note that the second option actually requires an additional column. So it actually requires a more complex database schema, and potentially more complex coding.
The right way to handle this situation will depend on the needs of the project.
But keep in mind that if you use โzeroโ to indicate BOTH meanings: โI donโt know what the inventory isโ and โI checked, and I verified that the inventory is zeroโโฆ that you are introducing ambiguity into the system unless you do something to differentiate these meanings.
Here is another example of when it would be a good idea to NOT allow null for a numeric field:
The latitude and longitude of a location can be stored as a pair of decimal
values. Here is an example:
Latitude: 33.428606
Longitude: -111.927360
But what if you want to store a location in the database before you know the latitude and longitude?
You COULD disallow NULL for these columns and set their default to zero.
But the problem with that is: Zero is a legitimate value for a latitude or longitude. Zero signifies the equator or the Prime Meridian.
So if you set the default value to zero, and disallow NULL, how do you know if any given value in the database is unknown versus actually being at the zero position?
You canโt use a negative number as a placeholder, either (e.g. โ-1โ or โ-99โ), because negative values are legitimate values as well. (And that would be kind of deceptive anyway!)
So I would set these columns to allow null, and I would record them as null in the database if the information was not providedโฆ if the data was submitted without latitude and longitude info.
There are other reasons to use NULL. This is the main reason.
What RDBMS should you use?ยถ
The abbreviation โRDBMSโ is short for โrelational database management system.โ
Although we donโt always think of it as such, an RDBMS is a software application, like Microsoft Word or Adobe Photoshop. It needs to run on a computer somewhere. It is different in the sense that we typically do not launch it independently on our own computer. In a typical information system, an RDBMS is running on a remotely accessible server and allows many users to connect to it from various โfront-endโ applications, such as a mobile app, a web application, or a desktop application.
An RDBMS may be hosting multiple databases concurrently. It may allow one, a few dozen, or many thousands of users to connect to it concurrently.
Which should you use?
I donโt know. It depends on your situation. Some RDBMS are free and open-source. Some cost money to purchase or use. Some will work on your server of choice. Some wonโt. Some will work with specific front-end software that you want to use. Some wonโt.
There are many considerations that go into choosing an RDBMS. But a key thing to
understand is that all of them can utilize database designs which are optimized
for these key criteria:
data integrity
speed
maintainability
The same RDBMS can be hosted on a server which runs quickly or not so quickly. Some commercial hosts (such as AWS) intentionally throttle (limit) the speed of their databases for customers at lower-paying tiers.
For most information systems of small to moderate size, the choice of a specific
RDBMS is not going to be the key factor in the speed and efficiency of your
system. More important factors are:
- where it is hosted
- how you use it
When a database-based information system has a query which runs slowly, a page that loads slowly, an update that takes a long time, a report that makes you wait, etcโฆ
Nearly always, if your database system is having speed problems, it is NOT because you are using MS SQL Server instead of Oracle, or because you are using MySQL instead of PostgreSQL.
It isnโt the choice of the RDBMS that is causing the problem. The problem stems
from one of these causes:
- the database design
- the SQL query design
- how the application source code was written
- the host server settings and configuration (such as memory, available hard drive, etc.)
Avoid NULL (usually)ยถ
Columns in SQL database tables can have values. Their value can also be set to NULL. Whether or not to allow an individual column to be set to NULL is an important decision in database design.
The importance of the NULL/NOT NULL decision is often overlooked. I often see inexperienced database designers use this incorrectly.
Simply put: When optimizing a database for:
- data integrity
- speed
- maintainability
โฆit is best to set all or most columns to NOT NULL.
This may seem counter-intuitive, depending on when, where and how a person first learned database design.
NULL means that you donโt know the value, right?
So letโs take this table:
Table: USERS
ID
middle_name
Maybe we want to collect names of users. We block rows from being created without a first and last name. But we donโt want to require users to enter a middle name or middle initial. In the front-end interface, we leave that field optional.
So if a user doesnโt provide a middle name, should we store that as NULL, because we donโt know the value?
No.
Using NULL is indeed a โsemantically pureโ decision. But we are not optimizing our database for โsemantic purity.โ We are (instead) optimizing our database for data integrity, speed, and maintainability.
Allowing the middle_name column to be NULL introduces an additional state or property to the column. This actually increases the memory requirements of the column. It may be a very slight amount, but with a large table, it is faster to deal with columns that do NOT allow null.
And queries are more complex if you allow NULL. Queries may need to use functions to check for null status, instead of simply querying columns directly.
Where clauses and joins are particularly trick. Many queries which use a column which allows null will fail if not handled properly. One might run a query that is supposed to return 100 rows of data. But it only returns 80 rows. Why? A programmer or user could spend a long time being baffled by the results until they realize that the query did not properly account for the NULL-able columns which were part of where clauses.
What are you going to do with that null value middle name? Youโre going to display it as blank on the front-end, or in the report.
How is that result any different than simply storing the middle name as a blank (empty string)? Itโs not. The result is exactly the same.
So by setting the column to NOT NULL, you reduce the complexity of the database table by eliminating one possible state and also eliminating one possible value which has no meaningful difference from another possible value.
If โNULLโ and โblankโ mean the same thing, then theyโre redundant. And it is better to use only one of them.
There ARE legitimate reasons to set a column to โallow NULL.โ I do use NULL-able columns in my database designs. But I use them cautiously and sparingly. I try to avoid using them whenever possible, but if there is a need for them, I use them.
When NULL-able columns should be used can be discussed another time.
camelCase or underscore_case?ยถ
The formatting of table names and column names within a database schema has been debated for decades. The same discussion occurs in relation to programming source code.
The discussions (arguments) go round-and-round. They will probably never end.
I donโt want to write anything lengthy about this. Let me point out a few general facts:
This relates specifically to optimizing for maintainability. This doesnโt make any difference when it comes to optimizing for data integrity or speed.
The most important decision on this topic is to be consistent. Stick with one format throughout the database design. Otherwise, people will type in the wrong column names and table names, and that will cause errors.
Although some RDBMS are case-insensitive with regards to table names and column names, some are case-sensitive. Moreover, the programming languages you use to interact with a database may be case-sensitive. Donโt ever be sloppy with regards to case. Always capitalize names consistently. Never use alternatively-capitalized variants to signify something different.
Before I whether or not you should use camelCase or underscore_case for naming
tables and columns, let me point out that there ARE other alternatives, which I
find even less preferable than these two naming conventions:
- alllowercaseruntogether
- ALLCAPSRUNTOGETHER
- spaces between words
- dashes-between-words
- ALL_CAPS_WITH_UNDERSCORES
These alternative formats, which you may see in some databases, are all inferior. They are either difficult to read, or they are error prone. Some of these formats might even seem impossible, such as naming tables and columns with spaces in between words. In most RDBMS, something like this IS possible, itโs just a very bad idea, because such a name only works by enclosing it to force the system to recognize it as a string, such as by enclosing it within double-quotes. Thatโs just asking for trouble, though. Also, there may be places where it wonโt work at all, so you would end up with a table schema which is not very portable.
I do not use camelCase in table and column names. I use underscore_case.
Two main reasons: I find that underscore_case is easier to read.
Not everybody agrees. But I think most people agree.
The other main reason I use underscore_case: It is programmatically very easy to resolve into a human-readable word, phrase or label.
For example, if I want to automatically convert a table to a form that is presented on a user-interface screen to be seen by human users, I might want to convert the name of a table and its columns to titles and labels. It is easy for any program (including a โreplaceโ command within SQL) to convert underscores to spaces, and thus make a human friendly label. Like this:
original_product_name => original product name
But what if a column is like this: originalProductName
Not so easy is it? A clever programmer using an application programming language can come up with an elegant function to handle this. But can it be done easily within a pure SQL query statement? Not really.
And even the cleverest programmer is going to run into trouble working with something like this:
originalProductUPCCode
How would you easily convert that to something human-readable? Itโs not even very readable in camelCase.
Compare that to this:
original_product_UPC_code
You can see how this is much easier to read as part of a schema. And it is much easier to utilize in automated name conversion scripts and functions.
My advice:
- Be consistent.
- Donโt go to war over naming conventions if youโre a guest in an already-established database.
- if you have a choice, use underscore_case.
When to Index?ยถ
Indexing is a awesome. It really is like a magic bullet to turbo-charge the speed of your database system.
But that doesnโt mean you should index everything all the time. High-quality database design requires an awareness of what indexing means for your database, including when to use it and when to NOT use it.
One of the most common โbig mistakesโ I have seen in database schemas created by programmers inexperienced in database design is that they donโt add any indices to tables that really need them.
They might be a programmer creating a new app or web application, and they create a database that their system needs. They add a few test rows, connect the database to the front-end, and everything works fine. So they think theyโre done.
And they are done. As long as the table is small. For a few rows or a few hundred rows, having an index is not going to matter. But then their system grows. More people use it. Now they have 10,000+ rows in that table, or 100,000+ rowsโฆ And their whole system starts to get slower, and slower, and slower. Why?
Because their system involves a search on the โnameโ column within that 100,000+ table. That search is taking a long time, although it was previously very fast. Add an index to the โnameโ column and like magic, the queries begin returning results instantaneously, just like when the table only had 100 rows in it.
Donโt wait to add an index that the table will need when it grows.
If a table might grow to be large enough that indexing will make a difference, add the index to the columns that need it right from the beginning. This will mean your design is really โfinishedโ and you wonโt need to monitor the system for the point in time when it starts to slow down because the table is getting too big to operate quickly without additional indices.
So we know that adding an index to a table can speed it up tremendously. Does that mean we should simply index every column right from the start?
No. Donโt index every column.
I only add an index to a column if it will be beneficial. I donโt do it by default.
There are many tables that may have a dozen or a few dozen columns, but which only need to have one or two of them indexed.
Here is a very simple guide about when to add an index to a column:
- add an index to columns that are uses as SEARCH criteria
- add an index to columns that are used in a โSORT BYโ clause
- add an index to columns that need to be referenced by FOREIGN KEY LINKS
- add an index to columns that are used in any JOINS
Note that there other index types aside from the standard index: unique contraints and primary key indices and others. We will not discuss those index types today, except to point out that if a column already has been indexed using one of these other index types, it does NOT need to be indexed again. You donโt need to index the same column twice. A unique constraint index (for example) does double duty: preventing the same value from being used twice in a column AND also provides the speed optimization that a non-unique index provides.
Canโt I just index everything and not think about it?
No, you shouldnโt do that. Although indexing is great when you can benefit it, indexing isnโt โfree.โ
Every index you add DOES increase overhead on the system. Indices take up file space. Indices require additional processing time when inserting rows. Indexing columns unnecessarily will create a net drain on your system rather than a boost.
A truly interactive information system which connects many relational tables to each other (joins, foreign keys), allows a user to conduct searches and to sort data using different criteria is likely to have MANY indexed columns. But it wonโt have EVERY column be indexed.
Why โIDโ?ยถ
In a previous entry I suggested that when designing a new database, the best name for an โID columnโ (โprimary identity columnโ or โprimary key columnโ) is simply:
ID
Yetโฆ if you have seen a wide range of databases created by different people using different RDBMS, covering different periods of time, you may have seen many different naming conventions. Here are some examples:
We have have seen various databases which use different names: ID id Id state_ID state_id state_Id STATEID StateID StateId stateid state_num state_primary_key
Why is โIDโ the best name to use?
Let us put aside the interesting fact that some software and source code libraries specifically look for this name and provide some benefits when using it. That is really a minor point. And it is NOT a โuniversalโ thing. Not by a longshot.
I like to use โIDโ because it is very readable and instantly recognizable. It
really stands out as something distinctive and different from the other column
names. Look at this example of column names for a single table:
ID
name
abbreviation
description
population
capitol
I like the way that the capitalized form โIDโ stands out.
Also, if I reference this column name in a foreign key column (linking from another table), I like how it stands out from the table name:
state_ID
I want to consistently use the same primary identity column name as a part of foreign key column names. When I use โIDโ, I can pick that part of a column name out quickly and easily.
One final question: Why donโt I use a naming convention like this for the ID
columns:
STATES
state_ID
name
abbreviation
I have seen this in some database designs. In these designs, there are NO primary identity columns named โIDโ. These columns are all named something different.
Donโt do this.
This introduces unnecessary complexity and duplication into your database design.
Your goal should be to make the database design as simple and as non-duplicative as necessary.
If you add a version of a table name in the tableโs primary identity column, then your database is NOT as simple.
Instead of having ONE name for ID columns (โIDโ), you end up having many. You would theoretically have as many different names for ID columns as you have tables.
A table with 20 table would have 20 different tables would have 20 different names for primary identity columns. 20 is NOT as simple as 1.
And you have also introduced duplication. Because what you really have, if you
reference the โfull nameโ of these columns is this:
states.state_ID
users.user_ID
products.product_ID
See how each column DUPLICATES information?
If I have an ID column within โstatesโ table, I donโt need to name the column โstate_ID.โ I already know that the โIDโ column within the states table is the ID column for states.
See how these column names avoid unnecessary duplication:
states.ID
users.ID
products.ID
So to summarize my advice on this topic:
- keep it simple
- make it easy to read
- avoid duplication
- use โIDโ
Naming ID Columnsยถ
I want to discuss one of the most important aspects of database design: naming ID columns.
What are โID columnsโ? This is one simple and common way to refer to primary identity columns.
For example, in a table like this:
STATES
ID 101
Name Alabama
Code AL
โฆthe โID columnโ is the first column: โIDโ.
This is the column within the table that is intended to be unchanging, and it is intended to be the most reliable way to reference a row in a table. These columns are also known as the โprimary key.โ There are some technical distinctions between the complete meanings of these terms, but that is a topic for another day.
Many techniques impact two or even three areas of database optimization (data integrity, speed, and maintainability.) But naming ID columns is something that is really ONLY related to ONE of these areas of optimization: maintainability.
This IS important, even though the database engine itself doesnโt really care. Your database is not going to run faster due to the column names you use. The technical ability of your database to be able to enforce data integrity will not change.
But your ability of human user and developers to maintain the database will be significantly impacted.
Your naming conventions can positively or negatively impact the human actions that have an effect on data integrity. So I suppose we could say that how you name ID columns impacts โone and a halfโ areas of optimization.
We have have seen various databases which use different names: ID id Id state_ID state_id state_Id STATEID StateID StateId stateid state_num state_primary_key
How should you name your ID columns?
The most important answer to this question is:
CONSISTENTLY.
Because if you are consistent, your database will be maintainable.
If you are not consistent, then mistakes will happen. Subtle bugs will creep in that are hard to track down. The ad hoc queries that users write wonโt work.
BE CONSISTENT!
So many choices! Argh! Just tell me what to do!
Okay: Here is a short answer to what to do:
If you are coming to an already-established database and you are being asked to use it but not recreate its naming conventions, then just BE CONSISTENT. Use whatever naming convention is already in place.
If you are adding a new table to a database in which ID columns all look like this: โidโ, then that is what you should use.
Simple.
But if you are designing a database from scratch, you can use the convention you prefer. This may be a slightly โcontroversialโ decision. The preferred format may vary depending on the specific RDBMS being used.
I will tell you that in working with MySQL databases, the convention I see most often in โbest practicesโ databases, and the convention I personally use in creating new database is to always use: ID
Two letters only. Capitalized. Always and consistently when I create new databases, I use โID.โ
Some MySQL tools actually recognize this column name and provide you with a few extra benefits when you use โID.โ For example, phpMyAdmin will automatically provide you with in-line editing functionality on query result screens in which the ID column is โIDโ, but doesnโt provide this functionality when ID columns are spelled or capitalized differently. Maybe this will change in the future, but for now, itโs a significant advantage.
So when confronted with the question about how to name an ID column, my simple answer is:
Use the naming convention already in place within your database
Use โIDโ
(Tomorrow, Iโll explain more reasons for using โIDโ.)
Normalization Example: Statesยถ
I want to discuss one specific data concept: States.
As with most any specific data concept example, this discussion serves a dual purpose. It presents ideas about how a specific type of data can be handled, and it also serves as an example of root principles.
So we will talk about how to handle states, which is a common, useful concept. But this example also illustrates principles for optimizing the database for data integrity (through normalization) and for speed.
Sometimes I see databases which store contact information, such as a userโs address, and the table with contact information has a varchar (text string) column for โstate.โ
Often these are varchar columns that contain values such as โNYโ, โAZโ and โNSW.โ
I never do this. I never store states as text strings. Even in a small, simple database, it is better to store states in a separate table, such as โstatesโ or โlocationsโ, and then link an address to that table through an integer foreign key link.
So I may have a table like this: ID Name 1 Alabama 2 Alaska 3 Arizona
And in the table with contact information, we would store only the integer that references the states/locations table like this: state_ID = 1
(This means โAlabama.โ)
This will save all kinds of headaches.
What we do NOT want to have happen is somebody else on the team coming to us and saying:
โWhy are there only 90 customers from New York in this report? I know there are 100.โ
And then we look in the database and we have to tell them: โThere are 90 customers from New York, but there are also 5 customers from โN.Y.โ, 4 customers from โNYโ, and 1 customer from โNewYork.โ
If we store states as blind text strings in a varchar field, then we are asking to have problems with data integrity. People donโt always spell state names correctly. People donโt always get the abbreviations correct. So we want to constraint the possible values for states to a list that contains ONLY possible values.
And it isnโt that complicated to do so. There are only 50 states in the United States. Even if we add in all states and territories from Australia and the United States, and all provinces from Canada, and even the special military service mailing codes, there are still fewer than 100 items in our โstatesโ table.
If our database encompasses other countries, then we can license a comprehensive location data source, build our own or (most likely) either leave this blank or allow for a general โprovinceโ field for other countries. In practice, most international addresses work fine with a city name, a postal code and a country name, and donโt need a โstateโ field.
Normalizing states (storing values as foreign key-referencing integers such as 1, 4, and 40) instead of using varchars (โALโ or โAlabamaโ) will also improve the speed of your database.
If you have only a few hundred records, it wonโt matter. But if you have a large number of records, such as a hundred thousand or more, you will definitely notice a difference between how fast it takes your database to do a search for all records using a text string (โALโ) versus an integer (1).
Database Design: Three Areas of Optimizationยถ
Real database design is more than just creating a database schema that โworks.โ
Real database design means creating a database schema that works well. It should work well now, and it should work well in the future, as a project continues to be used and (in all likelihood) changes as new features are added or new situations are encountered.
Whenever I engage in the task of โdatabase designโ โ whether Iโm designing a database from scratch or redesigning an existing database โ I like to explain to project owners, project managers, and development teams that Iโm focusing on three areas of optimization:
data integrity
speed
maintainability
This helps everybody (including myself) stay focused on important goals and helps explain why I make the decisions that I make. These are straightforward concepts that everybody from non-technical people to highly experienced programmers can understand.
If you think about it, these same goals (or โareas of optimizationโ) should seem very similar to key โbest practicesโ used in non-database programming.
In practice, it is rare that I find a database project which needs to be optimized for some other goal.
Here are simple examples of these optimization concepts:
[optimization for: data integrity] Question: Why do we need to add a foreign key constraint to this column?
Answer: This will help guarantee that valid data is always stored in this column which references a foreign key. Even if a programmer messes up with integrity checking at the source code level, or even if a back-end database user attempts to inset invalid data, this foreign key constraint will ensure that only valid data is input into the table.
[optimization for: speed] Question? Why do we need to add an index to this column? The table already works without it?
Answer: This column is used by the front end as a key search field. The system will return results much faster if we index it.
[optimization for: maintainability] Question: Why do we have to change these column names? The app is already written to use โlocation_IDโ in most tables, and โlocation_Idโ in a few tables.
Answer: Then we need to change the appโs source code AND change the column names so that they all match. Things may work now. But as soon as anybody starts making changes, somebody will mis-type the column name, and case-sensitive source code will fail to work.
I find that that nearly every decision in database design can be explained as something that is done in order to optimize the database for one of these three areas: data integrity, speed, and maintainability.
Rather than doing database design based on a large collection of โtextbook rulesโ whose meanings and purposes are obscure, I like to use these key goals as a guiding philosophy.
Enum: Just Say Noยถ
There is a time and place for everything, so the saying goes. And I agree this is true for most database concepts and techniques.
But not for enum. Donโt use enum at all. Itโs a nasty habit.
Many database designers might have blissfully worked their entire careers without running into enum. But then they help out with somebody elseโs database and see these little critters all over the place.
So what is โenumโ? This is an odd data construct masquerading as a โdatatypeโ option within an SQL table. Instead of being a specific type of data (such as varchar, int, decimal, etc.), an enum is actually a LIST of items, such a list of varchar values.
If youโre thinking: โA list? Isnโt that what a table is for?โ
โฆThen my response is: Exactly.
A column which uses the โenumโ datatype in a table is essentially hiding a little table WITHIN a column. It may seem handy, but it is a complete violation of the SQL relational data model.
Enum columns are NOT part of the ANSI SQL standard. They are NOT universally accepted among SQL databases. They are NOT handled the same way by different SQL databases. So when one uses an enum, one ends up with a table design which is not easily or consistently portable.
โBut theyโre so convenient,โ some people might say. They can be used to store a discrete set of values, such as for a drop-down menu in a mobile app. An example might be a โstatusโ field which contains only these possibilities: โpendingโ, โin progressโ, and โcomplete.โ
Create an enum field and youโve got a varchar that only allows those values: pending in progress complete
But by doing that, youโre basically hiding these values in a place that isnโt where users of the database would look for it.
You canโt simply type in โselect * from status_typesโ.
There are no standard SQL queries for obtaining the possible values of an enum datatype column.
And what if you want to ADD a NEW status type? Are you ABSOLUTELY certain your system will NEVER need a new status type?
A few months into the project, it turns out you need a new status type: โunder review.โ
Can you just add that status to the enum set of values? Itโs not so simple. This change will actually require a change to the table schema. Which is fine if youโve got a tiny database. But what if that column is used in a table with 5 million records? In many RDBMS, adding a single string (โunder reviewโ) to that list will actually require the database software to create an entirely new table, with the new schema, and copy all of the record to it. You could wait an hour just to add โunder reviewโ to your list of possible values. It might seem far-fetched, but Iโve seen this. Itโs a pain.
But if you had a separate table for โstatus_types,โ it would take a microsecond to add that new fourth value to a tiny 3-row table.
So EVEN if you donโt care about standards, EVEN IF you donโt care that many standard database tools and techniques wonโt know what to make of enums, and EVEN if you donโt think your database schema will ever migrate to another type of databaseโฆ you could still run into major headaches if you use enum.
There are better ways (standard ways) to handle discrete, defined lists. Thatโs what relational databases are all about. Enum may seem convenient, but itโs really a cheap shortcut that will come back to bite you in the end. | https://slurp.readthedocs.io/en/latest/database.html | 2022-09-25T07:49:50 | CC-MAIN-2022-40 | 1664030334515.14 | [] | slurp.readthedocs.io |
User guide
How to invite company users to the company Datahub account
First of all, you have to define which level of access you would like to provide. There are three levels of access:
- Company level - access to all company assets
- Application level - access to all assets connected to the single app
- Group level - access to all assets connected to the single user group (Instance)
Then, follow the next steps: Datahub -> Management - > Access management
How to create a community and add app users to the community.
Our architecture allows you to use user groups (instances) as a community. To join the community or user group, please get an invitation code for a certain group and use it either in Zenroad based applications (open-source app) or via APIs.
Steps 1 - get invitation code: Datahub -> Management -> Invitation code
Steps 2 - Join a community:
Zenroad based products
Zenroad -> Settings -> join a company - > 'CODE'
'CODE' is a unique community/ user group ID. all users who use the 'CODE' will be automatically moved to the group. The changes will automatically appear in the Datahub.
API
How to enable Realtime data and point it to the 3rd party TMS/fleet platform
please go to the Datahub -> management -> realtime data
Then Enable the service to the selected group of users
Configure EMEI for your users. Be aware that we generate a virtual EMEI for each user automatically, so you can use them in your TMS system or set your own EMEI.
as the next step, configure your TMS/fleet management system server settings by providing IP and port

Chapter 10: Automating Snapshotsยถ
Throughout this chapter you will need to be root or able to
sudo to become root.
Automating the snapshot process makes things a whole lot easier.
Automating The Snapshot Copy Processยถ
This process is performed on lxd-primary. First thing we need to do is create a script that will be run by cron in /usr/local/sbin called "refresh-containers" :
sudo vi /usr/local/sbin/refreshcontainers.sh
The script is pretty simple:
#!/bin/bash # This script is for doing an lxc copy --refresh against each container, copying # and updating them to the snapshot server. for x in $(/var/lib/snapd/snap/bin/lxc ls -c n --format csv) do echo "Refreshing $x" /var/lib/snapd/snap/bin/lxc copy --refresh $x lxd-snapshot:$x done
Make it executable:
sudo chmod +x /usr/local/sbin/refreshcontainers.sh
Change the ownership of this script to your lxdadmin user and group:
sudo chown lxdadmin.lxdadmin /usr/local/sbin/refreshcontainers.sh
Set up the crontab for the lxdadmin user to run this script, in this case at 10 PM:
crontab -e
And your entry will look like this:
00 22 * * * /usr/local/sbin/refreshcontainers.sh > /home/lxdadmin/refreshlog 2>&1
Save your changes and exit.
This will create a log in lxdadmin's home directory called "refreshlog" which will give you knowledge of whether your process worked or not. Very important!
The automated procedure will fail sometimes. This generally happens when a particular container fails to refresh. You can manually re-run the refresh with the following command (assuming rockylinux-test-9 here, as our container):
lxc copy --refresh rockylinux-test-9 lxd-snapshot:rockylinux-test-9

# How to Change a Teamscale Project ID since 7.1
Teamscale supports a flexible project ID system that was introduced with its 7.1 release version. Setting and changing these IDs manually is an expert feature that is not necessary during regular operation. However, experienced project administrators may use it to deal with several complex use cases.
# Use Case Example: Managing Project Copies
Special circumstances may make it necessary to transparently create a copy of a Teamscale project on the same Teamscale instance as the original project, and to switch between these two projects in a way that is transparent to the end user.
For example, sometimes a prolonged reanalysis of a project may not be feasible because of availability requirements. If a change to the analysis profile of such a project needs to be performed, instead a new project can be created that duplicates the settings of the original project (but with an adapted analysis profile).
After analysis of the new project is completed, the switch from old to new project is performed, after which the user will access the new project rather than the old one. In this way, the necessary changes to the analysis profile can be made without any downtime.
# Teamscale Project ID Paradigms
Each Teamscale project is associated with a project ID. This is also referred to as the primary public project ID. In the Teamscale project configuration, it is displayed in the Advanced Settings as the Project ID option. This ID is the only one an end user will typically see, as it is the one that is used to define the URL where the project can be accessed. Additionally, this ID will be used in the UI to refer to this project whenever an ID needs to be displayed (for example, in the system logs view).
In addition to the primary project ID, a project may also have alternative project IDs. These can be set in the field directly below the primary ID. A project may have any number of alternative IDs, although these are completely optional.
The only difference between the primary ID and the alternative IDs is the UI behavior of Teamscale. End users will only see the primary ID of a project, but not the alternative IDs. In all other respects the IDs behave interchangeably. In particular, alternative IDs can be used in REST API calls in place of the primary project ID, and they may be used in URLs to link to the respective Teamscale project. Hence, alternative IDs can be used to preserve backwards compatibility of external systems that reference such URLs.
The primary and the alternative IDs of a project can be changed freely, as long as they don't conflict with any other project ID. In other words, project IDs are globally unambiguous over the complete Teamscale instance. ID changes take effect immediately and do not require a reanalysis of the project.
# Implications of Project ID Changes
WARNING
Even though project IDs can be changed freely, it is not always advisable to do so.
In particular, changing a project ID from
original-id to
new-id means that end users who have bookmarked the URL
https://<teamscale-server>/findings.html#/original-id will no longer be able to access this endpoint, until they have changed it to the new
https://<teamscale-server>/findings.html#/new-id.
In such cases, it may make sense to add
original-id to the set of alternative project IDs when renaming it to
new-id, allowing the user to keep the old bookmark.
Indeed, preserving backwards compatibility for such URLs is the primary use case of the alternative project IDs.
Keep in mind that project ID references may crop up in unexpected places, such as the merge request comments Teamscale can perform in code collaboration platforms, or in automated CI pipeline scripts that upload external data to a specific Teamscale project.
Hence, project ID changes should be kept to a minimum to avoid unintentional consequences.
Another aspect to keep in mind is the issue of project permissions. For example, if a specific user group is granted the view permission on a specific project, this will be done by project ID. If this project ID is changed, then the users will no longer be able to view the project. If the same project ID is entered as primary or alternative project ID of a second project, then the user group will be able to view the second project, but not the original one. This is the desired behavior for the example scenario mentioned above (migrating a user base transparently from one project to another), but it may not be appropriate for all use cases. Hence, permissions should be checked (and adapted as required) after changing any project ID. | https://docs.teamscale.com/reference/ui/project/changing-project-id/ | 2022-09-25T09:15:39 | CC-MAIN-2022-40 | 1664030334515.14 | [array(['/assets/img/project-advanced-settings.feec5f6e.png',

Testingยถ
Testing is done with the tox automation tool, which runs a pytest-backed test suite in the
tests/ directory. This FAQ contains some useful information about how to use tox on Windows.
Testing Requirementsยถ
In addition to the installation requirements for the package itself, running tests and building documentation requires additional packages specified by the
tests and
docs extras in
setup.py, along with any other explicitly specified
deps in
tox.ini.
The full suite of tests also requires installation of the following software:
Artleys Knitro version 10.3 or newer: testing optimization routines.
MATLAB: comparing sparse grids with those created by the function nwspgr created by Florian Heiss and Viktor Winschel, which must be included in a directory on the MATLAB path.
If software is not installed, its associated tests will be skipped. Additionally, some tests that require support for extended precision will be skipped if on the platform running the tests,
numpy.longdouble has the same precision as
numpy.float64. This tends to be the case on Windows.
Running Testsยถ
Defined in
tox.ini are environments that test the package under different python versions, check types, enforce style guidelines, verify the integrity of the documentation, and release the package. First, tox should be installed on top of an Anaconda installation. The following command can be run in the top-level
pyblp directory to run all testing environments:
tox
You can choose to run only one environment, such as the one that builds the documentation, with the
-e flag:
tox -e docs
Test Organizationยถ
Fixtures, which are defined in
tests.conftest, configure the testing environment and simulate problems according to a range of specifications.
Most BLP-specific tests in
tests.test_blp verify properties about results obtained by solving the simulated problems under various parameterizations. Examples include:
Reasonable formulations of problems should give rise to estimated parameters that are close to their true values.
Cosmetic changes such as the number of processes should not change estimates.
Post-estimation outputs should satisfy certain properties.
Optimization routines should behave as expected.
Derivatives computed with finite differences should approach analytic derivatives.
Tests of generic utilities in
tests.test_formulation,
tests.test_integration,
tests.test_iteration, and
tests.test_optimization verify that matrix formulation, integral approximation, fixed point iteration, and nonlinear optimization all work as expected. Example include:
Nonlinear formulas give rise to expected matrices and derivatives.
Gauss-Hermite integrals are better approximated with quadrature based on Gauss-Hermite rules than with Monte Carlo integration.
To solve a fixed point iteration problem for which it was developed, SQUAREM requires fewer fixed point evaluations than does simple iteration.
All optimization routines manage to solve a well-known optimization problem under different parameterizations. | https://pyblp.readthedocs.io/en/latest/testing.html | 2022-09-25T07:19:02 | CC-MAIN-2022-40 | 1664030334515.14 | [] | pyblp.readthedocs.io |
Volunteer assignmentsยถ
An "assignment" links a CiviCRM contact to a specific volunteering opportunity. After defining your opportunities, it's time to start assigning some volunteers to these opportunities!
Allowing volunteers to self-assignยถ
Volunteers can use the sign-up form to assign themselves to specific opportunities.
Manually Assigning Volunteersยถ
A user with the proper permissions (henceforth know as a "staff member") can sign anyone up to fill a volunteering opportunity.
- Go to Volunteers > Manage Volunteer Projects
- Find the project
- Choose Assign Volunteers
The Available Volunteers listยถ
The left side shows a list of "Available Volunteers" which is populated by either of the following actions:
- A volunteer uses the sign-up form and selects "Any" as the shift (which is only possible if "Allow users to sign up without specifying a shift" is checked while defining opportunities)
- A staff member manually adds a contact to this list by clicking Add Volunteer... below it.
This Avilable Volunteers list will persist even after closing Assign Volunteers. Think of it as the people you have "on deck", waiting to be placed into a specific opportunity.
Making and editing assignmentsยถ
Volunteers must be added to the Available Volunteers list before they can be assigned to any opportunities. After this list contains some contacts, make assignments using any of the following methods:
- Drag and drop volunteers from Available Volunteers to the red More Needed boxes below the opportunities.
- Click the triangle icon to the right of a volunteer and choose Move to or Copy to.
When an opportunity has reached the required number of volunteer assignments, CiviVolunteer won't allow any more.
Caution
When you assign a contact to an opportunity, CiviVolunteer does not check whether the contact is already assigned to a different opportunity, overlapping in time. You will have to take this logic into account to avoid double-booking volunteers.
Removing assignmentsยถ
To remove an assignment, use the arrow button and choose Move to or Delete.
Searching for volunteers based on skill levelยถ
If you have set up and collected custom data on volunteer skills and interests (using the "Volunteer Information" custom data set), you can quickly search for volunteers based on criteria within these fields as follows:
- Within Assign Volunteers, hover over the box for an assignment which is still in need of volunteers
- Notice a magnifying glass icon appear at the top right of this box
- Click the magnifying glass icon.
- Search, and select volunteers
Confirmation emailsยถ
When a person fills out the sign-up form, CiviVolunteer sends them a confirmation email with the project managers BCC'd. (This email is not sent when using "Assign volunteers".)
Tip
To edit the text in the confirmation email
- Go to Administer > CiviMail > Message Templates
- Select System Workflow Messages
- Find Volunteer - Registration (on-line) and click Edit.
How assignments are storedยถ
Assignments are activities, and thus are viewable within the Activities tab for each contact. This also means that you can used the activities fields within the Advanced Search for contacts to filter based on volunteering assignments to some extent.
Do not add assignments by creating new activities
CiviCRM will let you add a new "Volunteer" activity to a contact through the Activities tab on the contact's record, but don't do this. You need to create new assignments using one of the methods described above to receive all the expected functionality within CiviVolunteer.
Viewing a roster of all assignmentsยถ
To see a summary of all the volunteers signed up for opportunities within a given project, you can do any of the following:
- Use Assign Volunteers as a way to view the assignments
- Click on View Volunteer Roster (from the Manage Projects screen) to see a similar view
- Use a report to gain even more control over what data is displayed. | https://docs.civicrm.org/volunteer/en/latest/assignments/ | 2022-09-25T07:30:15 | CC-MAIN-2022-40 | 1664030334515.14 | [array(['../images/assign-volunteers.gif', 'Assign Volunteers screenshot'],

get
This is a paginated endpoint that retrieves a list of your tasks.
The tasks will be returned in descending order based on
created_at time. All time filters expect an ISO 8601-formatted string, like '2021-04-25' or '2021-04-25T03:14:15-07:00'
The pagination is based on the
limit and
next_token parameters, which determine the page size and the current page we are on. The value of
next_token is a unique pagination token for each page (nerdy details if you were curious). Make the call again using the returned token to retrieve the next page. | https://docs.scale.com/reference/list-multiple-tasks | 2022-09-25T08:36:27 | CC-MAIN-2022-40 | 1664030334515.14 | [] | docs.scale.com |

Setting a Custom BT Address - Production Approach
Introduction
The BLE stack usually derives the BT address (sometimes referred to as MAC address) of a device from its Unique Identifier, a 64-bit value located in the Device Information Page; this value is factory programmed and not modifiable. Since the BT address is only 48-bit long, part of the Unique Identifier is removed while deriving the address. See your device's reference manual for more details on the Device Information page.
To extract the Unique Identifier from a radio board (e.g., BRD4182A - EFR32MG22), you can issue the following command using Simplicity Commander in a windows command prompt.
$ commander device info
You should get an output similar to this, notice the Unique ID value:
Part Number : EFR32MG22C224F512IM40 Die Revision : A2 Production Ver : 2 Flash Size : 512 kB SRAM Size : 32 kB Unique ID : 680ae2fffe2886c5 DONE
You can see the derived BT address after flashing the Bluetooth - SoC Empty example to the same device and scanning nearby advertisers using the EFR connect mobile application. Figure 1 below shows the expected output:
Figure 1. BT address in EFR connect application
Notice how the address is the same as the Unique ID except for the middle 16 bits (0xFFFE), hence why the BT address is a derived value. As mentioned before, this is the usual way for the BLE stack to acquire the BT address. Nonetheless, Nonetheless, if there's a valid BT address entry in the non-volatile region of the device (NVM3 for series 2 devices and PS Store or NVM3 for series 1), this value is used instead. For more details regarding non-volatile regions in the BLE stack, see the following documentation:
- UG434: Bluetooth C application developer's guide - Chapter 7.1
- AN1135: Using Third Generation Non-Volatile Memory - Chapter 6
This document explains two methods to modify the non-volatile region to set a custom BT address. Both could be suitable options in a production context:
Custom Application method: The running application reads a token located in the User Data page, derives the BT address from it, and stores it in the non-volatile region. This token is easily programmable through Simplicity Commander.
Simplicity Commander method: Create a custom non-volatile region (NVM3) with the desired BT address with Simplicity Commander. Flash the output binary to the device. This option is viable only if you're using NVM3 as the persistent storage solution.
Note: The solutions underneath were tested on a BRD4182A (EFR32MG22) using the Bluetooth - SoC Empty example as a baseline.
Methods
Custom Application
This approach uses a custom function that leverages the sl_bt_system_set_identity_address and, sl_bt_system_get_identity_address APIs. The steps are as follows:
First, create a new Bluetooth - SoC Empty example for your board. Open the
app.c file of the project and copy the following code snippet. This is the custom function responsible for updating the BT address.
#define MFG_CUSTOM_EUI_64_OFFSET 0x0002 static void sli_set_custom_bt_address(void) { uint8_t *mfg_token = (uint8_t*)USERDATA_BASE + MFG_CUSTOM_EUI_64_OFFSET; bd_addr myaddr, cur_addr; uint8_t address_type; sl_status_t status; //Adjust token byte Endianness for(uint8_t i = 0; i < 6; i++) { myaddr.addr[i] = mfg_token[7-i]; } //Get current BT address: // Current address is derived from EUI64 in DEVINFO unless there's an NVM3 // valid entry status = sl_bt_system_get_identity_address(&cur_addr, &address_type); if (status != SL_STATUS_OK) { while(1); //Issue retrieving the status } //Compare current and desired BT address, IF NOT EQUAL update and reset // reset needed to apply BT address changes in stack if((memcmp(&cur_addr, &myaddr, 6)) != 0) { status = sl_bt_system_set_identity_address(myaddr,0); // set new BT address if (status != SL_STATUS_OK) { while(1); //Issue setting the address } sl_bt_system_reset(0); // reset } }
Then, still in the
app.c file, call the function inside the system boot event
sl_bt_evt_system_boot_id as follows:
switch (SL_BT_MSG_ID(evt->header)) { // ------------------------------- // This event indicates the device has started and the radio is ready. // Do not call any stack command before receiving this boot event! case sl_bt_evt_system_boot_id: //Set custom bt address address sli_set_custom_bt_address();
The following is a brief explanation of the function's operation:
- Retrieve the
MFG_CUSTOM_EUI_64token from the user data page.
- Adjust the byte endianness of the token to form the new BT address.
- Retrieve the current BT address.
- Update the BT address if the new BT address is different from the current one.
- Reset the system.
- This step is needed because during the BLE stack initialization, the BT address is determined.
The BT address is ultimately derived from the
MFG_CUSTOM_EUI_64 token in the User Data page in this example. Therefore, you should flash the token before executing the application. To do this, use the following Simplicity Commander command:
$ commander flash --tokengroup znet --token "TOKEN_MFG_CUSTOM_EUI_64:0000AABBCCDDEE11"
Note that the two initial bytes are 0x0000. The reason is that the token is 8 bytes long but, we only need 6 of them. You should get an output similar to this:
Writing 1024 bytes starting at address 0x0fe00000 Comparing range 0x0FE00000 - 0x0FE003FF (1024 Bytes) DONE
You can verify that the token was properly flashed using the following command:
$ commander tokendump --tokengroup znet --token TOKEN_MFG_CUSTOM_EUI_64
You should get an output similar to this:
# # The token data can be in one of three main forms: byte-array, integer, or string. # Byte-arrays are a series of hexadecimal numbers of the required length. # Integers are BIF endian hexadecimal numbers. # String data is a quoted set of ASCII characters. # MFG_CUSTOM_EUI_64: 0000AABBCCDDEE11
Finally, compile the modified Bluetooth - SoC Empty project and flash the application to your device. You'll also need a bootloader. Open the EFR connect application on your mobile phone and click on the Browser option to see a list of nearby advertisers. Figure 2 below shows the output of the application. It displays the new BT address after flashing the token and the custom Bluetooth - SoC Empty application.
Figure 2. Modified BT address (Custom application method)
Notice that the Device Name is Custom MAC. By default it should be Empty Example. You can modify this through the GATT configurator. For further details see the Getting Started with Bluetooth in Simplicity Studio v5 lab manual.
Simplicity Commander (Custom NVM3)
This method is a more advanced approach as it requires an understanding of the NVM3 and the available keys. In this case, the application is not customized; instead, Simplicity Commander is used to create a blank NVM3 region in an image file. This image is modified to add the desired BT address and flashed to the device. Note that this method will overwrite your whole non-volatile memory area, only use it at production or if you are sure that your NVM is empty. The steps are as follows:
First, generate a blank NVM3 image file using the following command:
$ commander nvm3 initfile --address 0x00074000 --size 0xA000 --device EFR32MG22 --outfile nvm3_custom_mac.s37
To determine the size of the NVM3, use the configuration of the "NVM3 Default Instance" software component as a reference. The Silicon Labs example projects set 5 flash pages by default, seen in figure 3 below. The page size depends on the device. For the EFR32MG22 each flash page is 8-kB. See your device's reference manual for details.
To determine the starting address, subtract six flash pages from the end address of the main flash (5 pages for the NVM3 and 1 page for manufacturing tokens). See [UG434 - Chapter 7.1][ug136_flash_chapter_link] for flash distribution details in the BLE stack.
The output of the command is a blank NVM3
.s37 binary that can be customized and flashed to the device, useful to create a default set of NVM3 data that can be written during production.
Figure 3. Default NVM3 page count
Next, add the desired BT address to the blank NVM3 image through a valid "key/value" pair. The "key" is specific to the BT address and defined in the BLE stack as 0x4002C. The "value" is the desired 48-bit address. You can add the entry to the blank NVM3 using two methods, the difference is the way the "key/value" pair is provided.
As an argument:
$ commander nvm3 set nvm3_custom_mac.s37 --object 0x4002c:1122334455AA --outfile nvm3_custom_mac.s37
Using a .txt file:
$ commander nvm3 set nvm3_custom_mac.s37 --nvm3file custom_eui48.txt --outfile nvm3_custom_mac.s37
The .txt file has a specific format. The block below shows the contents of the .txt file used for this example. For more information, see UG162 - Section 6.15.4 Write NVM3 Data Using a Text File.
0x4002c : OBJ : 1122334455AA
Optionally, you can verify that the entry was created in the custom NVM3 file through the following command:
$ commander nvm3 parse nvm3_custom_mac.s37
You should get an output similar to this:

Install Dockerยถ
Docker is available on multiple platforms. Check the following link to choose the best installation path for you:
If the above does not fulfil your requirements follow the link here .
Create & Execute the Dockerfileยถ
Docker automatically build images by reading the instructions you provide in the
Dockerfile. A
Dockerfile is a text document that contains all the command a user could call on the command line to assemble an image.
The
Dockerfile must start with the
FROM instruction. Below is an example of a
Dockerfile
# base image FROM ubuntu:latest # clean and update sources RUN apt-get clean && apt-get update # install basic apps RUN apt-get install -qy nano # install Python and modules RUN apt-get install -qy python3 RUN apt-get install -qy python3-psycopg2
Follow this link to know more about creating a
Dockerfile.
To login into your account
$ docker login
Executing the
Dockerfilecommands
To directly execute the file command use: $ docker build . (With this command <none> repo is created. To avoid this use the next command) Sending build context to Docker daemon 5.51 MB ... You can specify the name of the repository with: $ docker build -t your_name .
View all the Imagesยถ
To view all the top level images run
$ docker images The output: REPOSITORY TAG IMAGE ID CREATED SIZE ----------------------------------------------------------- your_name latest d6e415a70abf 8 seconds ago 210MB ubuntu latest 747cb2d60bbe 2 weeks ago 122MB
The above output states that the repository

Integrate data into Common Data Service for Apps
The Data Integrator (for Admins) is a point-to-point integration service used to integrate data into Common Data Service for Apps. It supports integrating data from multiple sourcesโfor example, Dynamics 365 for Finance and Operations, Dynamics 365 for Sales and SalesForce (Preview), SQL (Preview)โinto Common Data Service for Apps. It also supports integrating data into Dynamics 365 for Finance and Operations and Dynamics 365 for Sales. This service has been generally available since July 2017.
We started with first-party appsโfor example, Dynamics 365 for Finance and Operations and Dynamics 365 for Sales. With the help of Power Query or M-based connectors, we are now able to support additional sources like SalesForce (Preview) and SQL (Preview) and will extend this to 20+ sources in the near future.
How can you use the Data Integrator for your business?
The Data Integrator (for Admins) also supports process-based integration scenarios like Prospect to Cash that provide direct synchronization between Dynamics 365 for Finance and Operations and Dynamics 365 for Sales. The Prospect to Cash templates that are available with the data integration feature enable the flow of data for accounts, contacts, products, sales quotations, sales orders, and sales invoices between Finance and Operations and Sales. While data is flowing between Finance and Operations and Sales, you can perform sales and marketing activities in Sales, and you can handle order fulfillment by using inventory management in Finance and Operations.
The Prospect to Cash integration enables sellers to handle and monitor their sales processes with the strengths from Dynamics 365 for Sales, while all aspects of fulfillment and invoicing happen using the rich functionality in Finance and Operations. With Microsoft Dynamics 365 Prospect to Cash integration, you get the combined power from both systems.
See the video: Prospect to cash integration
For more information about the Prospect to Cash integration, see the documentation on the Prospect to Cash solution.
We also support Field Service integration and PSA (Project Service Automation) integration to Dynamics 365 for Finance and Operations.
Data Integrator Platform
The Data Integrator (for Admins) consists of the Data Integration platform, out-of-the-box templates provided by our application teams (for example, Dynamics 365 for Finance and Operations and Dynamics 365 for Sales) and custom templates created by our customers and partners. We have built an application-agnostic platform that can scale across various sources. At the very core of it, you create connections (to integration end points), choose one of the customizable templates with predefined mappings (that you can further customize), and create and execute the data integration project.
Integration templates serve as a blueprint with predefined entities and field mappings to enable flow of data from source to destination. It also provides the ability to transform the data before importing it. Many times, the schema between the source and destinations apps can be very different and a template with predefined entities and field mappings serves as a great starting point for an integration project.
How to set up a data integration project
There are three primary steps:
Create a connection (provide credentials to data sources).
Create a connection set (identify environments for connections you created in the previous step).
Create a data integration project using a template (create or use predefined mappings for one or more entities).
Once you create an integration project, you get the option to run the project manually and also set up a schedule-based refresh for the future. The rest of this article expands on these three steps.
How to create a connection
Before you can create a data integration project, you must provision a connection for each system that you intend to work with in the Microsoft PowerApps portal. Think of these connections as your points of integration.
To create a connection
-
Under Data, select Connections and then select New connection.
You can either select a connection from the list of connections or search for your connection.
Once you select your connection, select Create. Then you will be prompted for credentials.
After you provide your credentials, the connection will be listed under your connections.
Note
Please make sure that the account you specify for each connection has access to entities for the corresponding applications. Additionally, the account for each connection can be in a different tenant.
How to create a connection set
Connection sets are a collection of two connections, environments for the connections, organization mapping information, and integration keys that can be reused among projects. You can start using a connection set for development and then switch to a different one for production. One key piece of information that is stored with a connection set is organization unit mappingsโfor example, mappings between the Finance and Operations legal entity (or company) and Dynamics 365 for Sales organization or business units. You can store multiple organization mappings in a connection set.
To create a connection set
Go to PowerApps Admin center.
Select the Data Integration tab in the left-hand navigation pane.
Select the Connection Sets tab and select New connection set.
Provide a name for your connection set.
Choose the connections you created earlier and select the appropriate environment.
Repeat the steps by choosing your next connection (think of these as source and destination in no specific order).
Specify the organization to business unit mapping (if you are integrating between Finance and Operations and Sales systems).
Note
You can specify multiple mappings for each connection set.
Once you have completed all the fields, select Create.
You will see the new connection set you just created under the Connection sets list page.
Your connection set is ready to be used across various integration projects.
How to create a data integration project
Projects enable the flow of data between systems. A project contains mappings for one or more entities. Mappings indicate which fields map to which other fields.
To create a data integration project
Go to PowerApps Admin center.
Select the Data Integration tab in the left navigation pane.
While in the Projects tab, select New Project in the top right corner.
Provide a name for your integration project.
Select one of the available templates (or create your own template). In this case, we are moving the Products entity from Finance and Operations to Sales.
Select Next and choose a connection set you created earlier (or create a new connection set).
Make sure you have chosen the right one by confirming the connection and environment names.
Select Next and then choose the legal entity to business unit mappings.
Review and accept the privacy notice and consent on the next screen.
Proceed to create the project and then run the project which in turn executes the project.
On this screen, you will notice several tabsโScheduling and Execution historyโalong with some buttonsโAdd task, Refresh entities, and Advanced Queryโthat will be described later in this article.
Execution history
Execution history shows the history of all project executions with project name, timestamp of when the project was executed, and status of execution along with the number of upserts and/or errors.
Example of project execution history.
Example of successful execution, showing status as completed with # of upserts. (Update Insert is a logic to either update the record, if it already exists, or to insert new record.)
For execution failures, you can drill down to see the root cause.
Here is an example of a failure with project validation errors. In this case, the project validation error is due to missing source fields in the entity mappings.
If the project execution is in โERRORโ state, then it will retry execution at the next scheduled run.
If the project execution is in โWARNINGโ state, then you will need to fix the issues on the source. It will retry execution at the next scheduled run.
In either case, you could also choose to manually โre-run execution.โ
How to set up a schedule-based refresh
We support two types of executions/writes today:
Manual writes (execute and refresh project manually)
Schedule-based writes (auto-refresh)
After you create an integration project, you get the option to run it manually or configure schedule-based writes, which lets you set up automatic refresh for your projects.
To set up schedule-based writes
Go to PowerApps Admin center.
You can schedule projects in two different ways.
Either select the project and select the Scheduling tab or launch the scheduler from the project list page by clicking the ellipsis next to the project name.
Select Recur every and once you have completed all the fields, select Save schedule.
You can set a frequency as often as 1 minute or have it recur a certain number of hours, days, weeks, or months. Note that the next refresh won't start until the previous project task completes its run.
Also note that under Notifications, you can opt in for email-based alert notifications, which would alert you on job executions that either completed with warnings and/or failed due to errors. You can provide multiple recipients, including groups separated by commas.
Note
- Currently, we support scheduling 50 integration projects at any given time per paid tenant. However you can create more projects and run them interactively. For trial tenants, we have an additional limitation that a scheduled project would only run for first 50 executions.
- While we support scheduling projects to run every minute, please bear in mind that this may put a lot of stress on your apps and in turn impact overall performance. We highly encourage users to test project executions under true load conditions and optimize for performance with less frequent refreshes. In production environments, we do not recommend running more than 5 projects per minute per tenant.
Customizing projects, templates, and mappings
You use a template to create a data integration project. A template commoditizes the movement of data that in turn helps a business user or administrator expedite integrating data from sources to destination and reduces overall burden and cost. A business user or administrator can start with an out-of-the-box template published by Microsoft or its partner and then further customize it before creating a project. You can then save the project as a template and share with your organization and/or create a new project.
A template provides you with source, destination, and direction of data flow. You need to keep this in mind while customizing and/or creating your own template.
You can customize projects and templates in these ways:
Customize field mappings.
Customize a template by adding an entity of your choice.
How to customize field mappings
To create a connection set
Go to PowerApps Admin center.
Select the project for which you want to customize field mappings and then select the arrow between source and destination fields.
This takes you to the mapping screen where you can add a new mapping by selecting Add mapping at the top right corner or Customize existing mappings from the dropdown list.
Once you have customized your field mappings, select Save.
How to customize or create your own template
To create your own template
Go to PowerApps Admin center.
Identify source and destination and direction of flow for your new template.
Create a project by choosing an existing template that matches your choice of source and destination and direction of flow.
Create the project after choosing the appropriate connection.
Before you save and/or run the project, at the top right corner, select Add task.
This will launch the Add task dialog.
Provide a meaningful task name and add source and destination entities of your choice.
The dropdown list shows you all your source and destination entities.
In this case, a new task was created to sync User entity from SalesForce to Users entity in Common Data Service for Apps.
Once you create the task, you will see your new task listed and you can delete the original task.
You just created a new templateโin this case, a template to pull User entity data from SalesForce to Common Data Service. Select Save to save your customization.
Follow the steps to customize field mappings for this new template. You could run this project and/or save the project as a template from the Project list page.
Provide a name and description and/or share with others in your organization.
Advanced data transformation and filtering
With Power Query support, we now provide advanced filtering and data transformation of source data. Power Query enables users to reshape data to fit their needs, with an easy-to-use, engaging, and no-code user experience. You can enable this on a project-by-project basis.
How to enable advanced query and filtering
To set up advanced filtering and data transformation
Go to PowerApps Admin center.
Select the project where you want to enable advanced query and then select Advanced Query.
You will get a warning that enabling advanced query is a one-way operation and cannot be undone. Select OK to proceed and then select the source and destination mapping arrow.
You are now presented with the familiar entity mapping page with a link to launch Advanced Query and Filtering.
Select to link to launch the Advanced Query and Filtering user interface, which gives you source field data in Microsoft Excel-type columns.
From the top menu, you get several options for transforming data such as Add conditional column, Duplicate column, and Extract.
You can also right-click any column for more options such as Remove columns, Remove duplicates, and Split column.
You also can filter by clicking each column and using Excel-type filters.
Default value transforms can be achieved using the conditional column. To do this, from the Add Column dropdown list, select Add Conditional Column and enter the name of the new column. Fill in both Then and Otherwise with what should be the default value, using any field and value for If and equal to.
Notice the each clause in the fx editor, at the top.
Fix the each clause in the fx editor and select OK.
Each time you make a change, you apply a step. You can see the applied steps on the right-hand pane (scroll to the bottom to see the latest step). You can undo a step in case you need to edit. Additionally, you can go to the Advanced editor by right-clicking the QrySourceData on the left pane, at the top to view the M language that gets executed behind the scenes, with the same steps.
Select OK to close the Advanced Query and Filtering interface and then, on the mapping task page, pick the newly created column as the source to create the mapping accordingly.

Initialization is the process of making setting values "sane". To be considered sane, the setting value must have correct checksum, and its members must conform to the constraints of P1 and P2 parameters.
Non-volatile settings are never initialized automatically โ are always initialized when you call stg_start().:
sub on_button_released()
if button.time>4 then
if stg_restore_multiple(EN_STG_INIT_MODE_NORMAL)<>EN_STG_STATUS_OK then sys.halt
end if
end sub.
sub on_sys_init()
dim x as en_stg_status_codes
dim stg_name as string(STG_MAX_SETTING_NAME_LEN)
if stg_start()<>EN_STG_STATUS_OK then sys.halt
x=stg_check_all(stg_name)
select case x
case EN_STG_STATUS_OK:
'--- all good ---
case EN_STG_STATUS_INVALID, EN_STG_STATUS_FAILURE:
case else:
'some other trouble
sys.halt
end select
comms_init()
There is also a library procedure to restore a single member of a single setting โ stg_restore_member(). The default value for any member of any setting can be obtained by calling stg_get_def(). | http://docs.tibbo.com/taiko/lib_stg_verify_init.htm | 2018-12-10T00:27:28 | CC-MAIN-2018-51 | 1544376823228.36 | [] | docs.tibbo.com |

The โBrushesโ dialog is used to select a brush, for use with painting tools: see the Brushes section for basic information on brushes and how they are used in GIMP. The dialog also gives you access to several functions for manipulating brushes. You Paragraaf 2.3, โKoppelen van dialoogvenstersโ .
from the Tool Options dialog for any of the paint tools, by clicking on the Brush icon button, you get a popup with similar functionality that permits you to quickly choose a brush from the list; if you click on the button present on the right bottom of the popup, you open the real brush dialog.
The simplified โBrushesโ dialog
This window has five buttons, clearly explained by help pop-ups:
Smaller previews
Larger previews
View as list
View as Grid
Open the brush selection dialog
Note that, depending on your Preferences, a brush selected with the popup may only apply to the currently active tool, not to other paint tools. See the Tool Option Preferences section for more information.
In the Tab menu, you can choose betweenand . In Grid mode, the brush shapes are laid out in a rectangular array, making it easy to see many at once and find the one you are looking for. In List mode, the shapes are lined up in a list, with the names beside them.
In the Tab menu, the option Preview Size allows you to adapt the size of brush previews to your liking.
At the top of the dialog appears the name of the currently selected brush, and its size in pixels.
In the center a grid view of all available brushes appears, with the currently selected one outlined.
For the most part, the dialog works the same way in List mode as in Grid mode, with one exception:
If you double-click on the name of a brush, you will be able to edit it. Note, however, that you are only allowed to change the names of brushes that you have created or installed yourself, not the ones that come pre-installed with GIMP. If you try to rename a pre-installed brush,.
When you click on a brush preview, it becomes the current brush and it gets selected in the brush area of Toolbox and the Brush option of painting tools. When you double-click on a brush preview, you will activate the Brush Editor. You can also click on buttons at the bottom of the dialog to perform various actions.
Meaning of the small symbols at the bottom right corner of every brush preview:
A blue corner is for brushes in normal size. You can duplicate them.
A small cross means that the brush preview is in a reduced size. You can get it in normal size by maintaining left click on it.
A red corner is for animated brushes. If you maintain left click on the thumbnail, the animation is played.
You can use tags to reorganize the brushes display. See Paragraaf 3.6, . This removes all traces of the brush, both from the dialog and the folder where its file is stored, if you have permission to do so. It asks for confirmation before doing anything.
If you add brushes to your personal
brushes
folder or any other folder in your brush search path, by some
means other than the Brush Editor, this button causes the list
to be reloaded, so that the new entries will be available in the
dialog. a diamond. This editor has several elements:
The dialog bar: As with all dialog windows, a click on the small triangle prompts a menu allowing you to set the aspect of the Brush Editor.
The title bar: To give a name to your brush.
The preview area: Brush changes appear in real time in this preview.
Settings:
A circle, a square and a diamond are available. You will modify them by using the following options:
Distance between brush center and edge, in the width direction. A square with a 10 pixels radius will have a 20 pixels side. A diamond with a 5 pixels radius will have a 10 pixels width.
This parameter is useful only for square and diamond. With a square, increasing spikes results in a polygon. With a diamond, you get a star.
This parameter controls the feathering of the brush border. Value = 1.00 gives a brush with a sharp border (0.00-1.00).
This parameter controls the brush Width/Height ratio. A diamond with a 5 pixels radius and an Aspect Ratio = 2, will be flattened with a 10 pixels width and a 5 pixels height (1.0-20.0).
This angle is the angle between the brush width direction, which is normally horizontal, and the horizontal direction, counter-clock-wise. When this value increases, the brush width turns counter-clock-wise (0ยฐ to 180ยฐ).
When the brush draws a line, it actually stamps the brush icon repeatedly. If brush stamps are very close, you get the impression of a solid line: you get that with Spacing = 1. (1.00 to 200.0).
When you use the Copy or Cut command on an image or a selection of it, a copy appears as a new brush in the upper left corner of the โBrushesโ dialog. This brush will persist until you use the Copy command again. It disappears when you close GIMP. | https://docs.gimp.org/2.8/nl/gimp-brush-dialog.html | 2018-12-10T00:47:09 | CC-MAIN-2018-51 | 1544376823228.36 | [] | docs.gimp.org |
