Powershell error when using loaded assembly
|
<p>I’m having a problem with using zip compression in a Powershell script. The code snippet in question is:</p>
<pre><code>$zipfile = $targetFile
$file = 'Script.ps1'
$stream = New-Object IO.FileStream($zipfile, [IO.FileMode]::Open)
$mode = [System.IO.Compression.ZipArchiveMode]::Update
$zip = New-Object IO.Compression.ZipArchive($stream, $mode)
($zip.Entries | ? { $file -contains $_.Name }) | % { $_.Delete() }
# Add a newer Script.ps1 file with the new Comment Based Help template.
$newFile = "$PSScriptRoot\$file"
[System.IO.Compression.ZipFileExtensions]::CreateEntryFromFile($zip,$newFile,"Script.ps1","optimal")
# Clean up.
$zip.Dispose()
$stream.Close()
$stream.Dispose()
</code></pre>
<p>The code attempts to delete a file from the archive and then add a newer version of the same file. When I run the script, I receive the following:</p>
<blockquote>
<p>[ERROR] Unable to find type [System.IO.Compression.ZipArchiveMode].
Make sure that the [ERROR] assembly that contains this type is
loaded. [ERROR] At
C:\xxxxx\xxxxx\xxxxx\PowerShellIDEInstallers\PowerShel [ERROR]
lIDEInstallers\VSInstallCBH.ps1:141 char:2 [ERROR] + $mode =

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ [ERROR] +
CategoryInfo : InvalidOperation:
(System.IO.Compression.ZipArch [ERROR] iveMode:TypeName) [],
RuntimeException [ERROR] + FullyQualifiedErrorId : TypeNotFound
[ERROR]</p>
</blockquote>
<p>However, if I run it again, it will work correctly.
I found a few posts (<a href="https://stackoverflow.com/questions/12923074/how-to-load-assemblies-in-powershell">this</a> and <a href="https://stackoverflow.com/questions/29007742/unable-to-use-system-io-compression-filesystem-dll">this</a>) that spoke of similar problems. I’m currently using:</p>
<pre><code>Add-Type -AssemblyName System.IO.Compression.FileSystem
</code></pre>
<p>At the top of the script. I also found <a href="http://tfl09.blogspot.co.uk/2010/08/using-newer-versions-of-net-with.html" rel="nofollow noreferrer">this post</a> which looked promising, but, did not work. I should also add that the problem occurs in the ISE, Visual Studio, and the command prompt. The code will work if I run it a second time in any of the environments.</p>
<p>I’m baffled and at a loss. Can anyone tell me why this is happening?</p>

tvOS Button Action
|
<p>I create a UIButton in tvOS via Swift</p>
<pre><code>let randomBtn = UIButton()
randomBtn.setTitle("Zufällig", forState: .Normal)
let RndNormal = UIImage(named: "RndNormal")
let RndHoover = UIImage(named: "RndHoover")
randomBtn.setImage(RndNormal, forState: .Normal)
randomBtn.setImage(RndHoover, forState: .Focused)
randomBtn.setTitleColor(UIColor.blackColor(), forState: .Normal)
randomBtn.setTitleColor(UIColor.whiteColor(), forState: .Focused)
randomBtn.addTarget(self, action: #selector(ViewController.click(_:)), forControlEvents: UIControlEvents.TouchUpInside)
let screenSize: CGRect = UIScreen.mainScreen().bounds
let screenWidth = screenSize.width
randomBtn.frame = CGRect(x: screenWidth - 150, y: 60 , width: 70 , height: 70)
self.view.addSubview(randomBtn)
</code></pre>
<p>But the action never get fired if I press the button, is there anything different in tvOS?</p>
<pre><code>func click(sender: UIButton) {
print("click")
}
</code></pre>

How to make Netty client read entire response
|
<p>I have a Camel route that communicates with a COBOL server using a TCP socket connection. The route basically looks like this:</p>
<pre><code><route>
<from uri="direct:sendMessage" />
<log message="Sending message to server: ${body}" />
<to uri="netty4:tcp://hostname:1234?requestTimeout=2000&amp;encoding=windows-1252" />
<log message="Received response from server: ${body}" />
</route>
</code></pre>
<p>Calling this route results in the following exception:</p>
<pre><code>Failed delivery for (MessageId: ID-vmuxfusepoc01-34999-1467706512020-14-2 on ExchangeId: ID-vmuxfusepoc01-34999-1467706512020-14-1). Exhausted after delivery attempt: 1 caught: io.netty.handler.codec.TooLongFrameException: Adjusted frame length exceeds 1048576: 1008807217 - discarded

<p>After adding <code>textline=true</code> to the netty url the request is send correctly but only the first line of the servers response is returned by Netty to Camel. The server returns about 100 lines of text and then closes the connection.</p>
<p>I've tried using StringEncoder and StringDecoder but this gives me the same result as 'textline=true'.</p>
<p><strong>My question is:</strong> How can I configure Netty to return the entire response of the server as a String. Message delimiters are of no concern because exactly 1 message will be returned before the connection is closed by the server.</p>

Timed out while waiting for the machine to boot. This means that
Vagrant was unable to communicate with the guest machine within
the configured ("config.vm.boot_timeout" value) time period.
If you look above, you should be able to see the error(s) that
Vagrant had when attempting to connect to the machine. These errors
are usually good hints as to what may be wrong.
If you're using a custom box, make sure that networking is properly
working and you're able to connect to the machine. It is a common
problem that networking isn't setup properly in these boxes.
Verify that authentication configurations are also setup properly,
as well.
If the box appears to be booting properly, you may want to increase
the timeout ("config.vm.boot_timeout") value.

Android App crashes when running on Windows 10 and VS2015 Android Emulator
|
<p>Been trying to figure this out for a while but with no luck...</p>
<p><strong>Background:</strong></p>
<p>I am trying to run a Xamarin.Forms application within an Android Emulator through Visual Studio 2015 (update 3) on Windows 10. I installed all the required Android SDK and also ran against different emulators ranging from 4.4 Kitkat to 6.0 Marshmellow and I get the same results. The app is built with Xamarin.Forms with the pages in a portable C#/XAML project. #rd paty library FreshMVVM is used for IOC and ViewModels</p>
<p><strong>Issue</strong></p>
<p>The app mostly starts up first time but I typically have to wait 20-30 sec after deploy to run the app otherwise the app crashes straight away but the real issue is that when I get to the first page with a button on it (navigating to LoginPageModel), clicking the button will crash the app. The logcat Android Device Logging Window prints out the following during the crash... (sensitive info masked)</p>
<p>Things I have tried:</p>
<ul>
<li>Removing constructor code from LoginPageModel class ... no change</li>
<li>Removing XAML. Mostly works but experience is inconsistant. Maybe related to the Xamarin forms controls?</li>
<li><p>Conrols used are: ContentPage, Image, ContentView, StackLayout, Entry, Label, Switch, Button</p>

failed to use iconv to change encoding in shell
|
<p>I have a file to convert its encoding.
In terminal, I have :</p>
<pre><code>$file -i *
</code></pre>
<p>and it turns out <code>text/plain; charset=us-ascii</code></p>
<p>Then I have this command line :</p>
<pre><code>$ iconv -f us-ascii -t UTF-8 oldfile.txt > newfile.txt
</code></pre>
<p>It turns out a message: <code>iconv: illegal input sequence at position 2575661</code> </p>
<p>I searched and found that this suggests there are invalid sequences (for instance this page <a href="https://spin.atomicobject.com/2011/07/13/some-useful-iconv-functionality/" rel="nofollow">https://spin.atomicobject.com/2011/07/13/some-useful-iconv-functionality/</a>). I am wondering what would be the most reliable way to convert the encoding to the most appropriate encoding to sqlite, and how to find the invalid sequences? Thank you!!</p>

In spark and scala, how to convert or map a dataframe to specific columns info?
|
<p>Scala.<br>
Spark.<br>
intellij IDEA. </p>
<p>I have a dataframe (multiple rows, multiple columns) from CSV file.<br>
And I want it maps to another specific column info.<br>
I think scala class (not case class, because columns count > 22) or <code>map()</code>..... </p>
<p>But I don't know how to convert them.</p>
<p>Example</p>
<p>a dataframe from CSV file.</p>
<pre><code>----------------------
| No | price| name |
----------------------
| 1 | 100 | "A" |
----------------------
| 2 | 200 | "B" |
----------------------
</code></pre>
<p>another specific columns info.</p>
<pre><code> => {product_id, product_name, seller}
</code></pre>
<p>First, <code>product_id</code> is mapping to 'No'.
Second, <code>product_name</code> is mapping to 'name'.
Third, <code>seller</code> is <code>null</code> or ""(empty string).</p>
<p>So, finally, I want a dataframe that have another columns info.</p>
<pre><code>-----------------------------------------
| product_id | product_name | seller |
-----------------------------------------
| 1 | "A" | |
-----------------------------------------
| 2 | "B" | |
-----------------------------------------

React-router: difference between history.push and location.href in flux app?
|
<p>I'm a bit new with React, react-router, and flux, and I'm curious.
I'm curious, what's the difference between the 2 types of link click handling.
My feeling is <code>location.href</code> may "reset" the application, like if page was reloaded.
Is that right or wrong? And what's the difference between the 2 methods? Cause I'm not always able to use <code>history.push</code> in the application.</p>
<p>Thanks a lot in advance!</p>

How to make the Jump animations using curves smoothly?
|
<p>I've been working on an endless runner game using unity 5 engine studying some examples. I applied jump action to my character. It did work fine but I wanted it to be bit perfect so I implanted the jump using curves with this <a href="https://i.stack.imgur.com/asx0r.png" rel="nofollow noreferrer">example</a>, came across this issue. That is after applying curves for the character controller with some adjustments, now when I jump, the curves starting to adjust the controller after I touched a platform (the ground) which make the jump unrealistic. I did tried to achieve the jump using fixed Update method, since the game is an endless runner which basically updates everything frame by frame it did not work.
How do I achieve a realistic jump? below is what I tried so far.</p>
<pre><code>if (controller.isGrounded)
{
verticalVelocity = -0.5f; //upward thrust / jump height
if (currentBaseState.fullPathHash == locoState) // is character in moving state
{
if (Input.GetButtonDown("Jump"))
{
verticalVelocity = 18f;
anim.SetBool("Jump", true);
}
}
else if (currentBaseState.fullPathHash == jumpState) //Is character in jump state
{
if (!anim.IsInTransition(0))
{
if (useCurves)
{
controller.height = anim.GetFloat("ColliderHeight"); //get the controller height using curves
controller.center = new Vector3(0f, anim.GetFloat("ColliderY"), 0f); //Get the controller Y axis using the curves (center of chr ctrlr)
}
anim.SetBool("Jump", false);
}
// Applying curves
Ray ray = new Ray(transform.position + Vector3.up, -Vector3.up);
RaycastHit hitInfo = new RaycastHit();
if (Physics.Raycast(ray, out hitInfo))
{
print(ray.ToString());
if (hitInfo.distance > 1.75f)
{
anim.MatchTarget(hitInfo.point, Quaternion.identity, AvatarTarget.Root, new MatchTargetWeightMask(new Vector3(0, 1f, 0), 0), 0.03f, 0.6f);
}
}
}
}

Cannot click on HTML input button with Javascript and WebView (Possibly an iframe issue, not sure)
|
<p>I am working on an iOS app that performs some actions in a webview using injected javascript. I am trying to press a submit button on a router's web-interface (So I can't give you a url). I've tried many other proposed solutions online but nothing is working. One thing I must do is click an input button of type=SUBMIT and for whatever reason it is not responding. I have tried using .click() along with calling the onClick event handler, but nothing is working. Any help is appreciated. The HTML code is below:</p>
<pre><code><div class="fix_button">
<table width="100%" border="0" cellpadding="0" cellspacing="2">
<tbody>
<tr>
<td nowrap="" colspan="2" align="center">
<input class="cancel_bt" type="RESET" name="Cancel" value="Cancel" onclick="doCancel();" languagecode="51">
&nbsp;
<input class="apply_bt" type="SUBMIT" name="Apply" value="Apply" onclick="return checkData();" languagecode="50">
</td>
</tr>
</tbody>
</table>
</div>
</code></pre>
<p>The input button is the one with the <code>class="apply_bt"</code>. This div is within an iframe and submits data that is within another iframe within this frame. The structure is sort of like this:</p>
<pre><code><iframe>
// Contains the Apply Button
<div class="fix_button"></div>
// Contains the iframe where the info to be submitted is
<div id="main" class="main_top_button">
// Contains data to be submitted
<iframe src="WLG_2g_wireless2.htm&amp;todo=wifi_primary_init" id="2g_setting" name="wl2gsetting" onload="SetCwinHeight(this.id)" marginheight="0" marginwidth="0" scrolling="no" width="100%" frameborder="0" height="288px">
</iframe>
</div>
</iframe>
</code></pre>
<p>This is the code I am using to click the button:</p>
<pre><code>// Gets the outer iframe
iframe1 = document.getElementById("formframe");
// Gets the html within the iframe
var innerDoc=iframe1.contentDocument || iframe1.contentWindow.document;
// Gets iframe within the iframe
innerframe = innerDoc.getElementById("2g_setting");
// Gets the html within the inner iframe
var innerDoc2=innerframe.contentDocument || innerframe.contentWindow.document;
// I Enter some data in the inner iframe (not shown), this portion
// of the code works perfectly. I can see fields being entered and
// buttons being clicked.
// Then I click the apply button...
innerDoc.getElementsByName("Apply")[0].click()
// And nothing happens
</code></pre>
<p>I am able to get the element and read data from the Apply Button, such as its text, but I am not able to perform a .click() action on the button. Also, I am not getting any errors. I have no idea why its not working. Please help!</p>

How do I remove all types of translation from wordpress site?
|
<p>Few days ago I installed my website with Bitnami with Azure Cloud server. I installed WordPress as my site, but Bitnami WordPress comes with all kind of language translation. I always use English and don't like to see any translation.</p>
<p>Problem is when ever I update any plugin or theme it also comes with all of those translation. I didn't start posting on my site. Also I searched everywhere for this solution but there are no solution what I'm looking for. </p>
<p>Is there any way to only use English as my site language and remove all those translation?</p>

Spring resource resolver with different maven modules
|
<p>So for our test structure we currently have a base module in which we have some of our common configuration files etc (example: ds.properties). Now I'm currently running tests in a different module and I'm trying to load all .properties files (to get all the configurations) and I was using </p>
<pre><code>(new PathMatchingResourcePatternResolver(getClass().getClassLoader())).getResources("classpath:*.properties")
</code></pre>
<p>Now this is only finding alpha.properties (the property file in my module). Is there a way to get the property files in all modules?</p>
<p>Some stuff I have already tried:</p>
<pre><code>(new PathMatchingResourcePatternResolver(getClass().getClassLoader())).getResources("classpath:ds.properties")
</code></pre>
<p>Returns the ds.properties that I want but obviously not auth.properties.</p>
<pre><code>(new PathMatchingResourcePatternResolver(getClass().getClassLoader())).getResources("classpath*:*.properties")

Tess4j Tesseract vs Tesseract1
|
<p>I am not 100% sure the difference about Tesseract and Tesseract1 object in the Java api package Tess4J, anyone can explain about it?</p>
<p>I know Tesseract uses interface mapping, and Tesseract1 uses direct mapping. How this will change their behavior?</p>
<p>Thanks in advance!</p>

ImageButton.getWidth() and getHeight() returns 0
|
<p>Currently in my android app, my ImageButton <code>getWidth()</code> and <code>getHeight()</code> returns 0. Upon searching the forums, I realized that this is because the Layout/View hasn't been done/finalized by the OS, hence returning 0. Thus, they recommend using the <code>OnGlobalLayoutListener</code> to solve this issue. However, the button is created in a Fragment, which has an <code>onCreateView()</code> method which returns the View of the fragment. So how do I attach this Listener in this case?</p>
<p>Thanks.</p>

Get an element in DOM hierarchy from the link function of a directive [AngularJS]
|
<p>I have a simple DOM hierarchy and I want to grab a specific set of elements (I want all the <strong>canvas</strong> elements). This is the entire template for this directive:</p>
<pre><code><div id='charts-container'>
<div class='chart-wrapper' ng-repeat='chart in getNumberOfCharts() track by $index'>
<canvas id="{{'exam-chart-' + $index}}" class='chart-canvas'></canvas>
</div>
</div>
</code></pre>
<p>I want to create a list with all the canvas within the <em>#charts-container</em> element, but I just can't. This is what I'm trying to do inside the link function:</p>
<pre><code>link: function (scope, element, attributes, controller) {
var look = element.find('#chart-canvas');
$log.debug(look);
}
</code></pre>
<p>And then I get <a href="http://i.imgur.com/0Ejlk8d.png" rel="nofollow">this</a> element, but I don't know how to get all the chart-wrapper elements from here.</p>
<p>I tried doing <code>look.context.children</code>, it returned an empty list, but at the same time showed me what I wanted as if the list were populated, here is an <a href="http://i.imgur.com/dWqxVLP.png" rel="nofollow">image</a>. If I try to access any index of this list, it returns undefined (which is fine, because it's an empty list. But why the console is showing me these values?)</p>
<p>What is the best way to achieve this? To get all the canvas elements in this template? (there are 15 of them). Thanks!</p>
<hr>
<p><strong>--- UPDATE ---</strong> </p>
<p>I realized that if I remove the <strong>ng-repeat</strong> attribute I'm using in the template, it works! But I need the ng-repeat...</p>
<p><code>element.find('.chart-canvas')</code> manage to get the canvas element, but only if there are no ng-repeat attribute.</p>
<p>Is this a common issue when using ng-repeat. Is there any special treatment when falling in this case?</p>

Is a full clone the only way to submodule add a branch?
|
<p>I want to add a submodule that references a specific (non-master) branch. The following will only grab the master branch due to <code>--depth=1</code>, so the command will inevitably fail;</p>
<pre><code>git submodule add -b myBranch --depth=1 [email protected]:some/large/repo
</code></pre>
<p>Because <code>submodule add</code> doesn't support <code>--single-branch</code>, does this mean my only option is to clone the entire repo?</p>

Android studio proguard not working for library aar even if minifyenabled true
|
<p>I have a Gradle app with 1 library aar project and few flavours, I am trying to implement proguard for library project.</p>
<p>I have declared proguard-rules.pro file as well as proguard-library.pro file. I have minifyenabled true, useproguard true but Proguard does not seem to work. I am using Android studio 2.1.2 with a gradle wrapper 2.10.</p>
<p>I also followed steps from the link below but did not work, <a href="https://stackoverflow.com/questions/26983248/proguard-ignores-config-file-of-library/27052696#27052696">Proguard ignores config file of library</a></p>
<p>Can someone help to get proguard to run for my library aar project.</p>
<p>Edited:
I am just testing if proguard works for debug or not, My gradle file is as below:</p>
<p>Edited debug code below:</p>
<pre><code>defaultConfig {

Eloquent is saving no values in not null fields
|
<p>I'm making a migration and I want some fields to be not nullable. To make easier I will use the users migration that comes with Laravel as an example.</p>
<pre><code>Schema::create('users', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->string('email')->unique();
$table->string('password');
$table->rememberToken();
$table->timestamps();
});
</code></pre>
<p>None of its fields are nullables but if I make:</p>
<pre><code>$user = new User();
$user->save();
User::all();
</code></pre>
<p>It returns </p>
<pre><code>Illuminate\Database\Eloquent\Collection {#639
all: [
App\User {#640
id: "1",
name: "",
email: "",

updated_at: "2016-06-29 15:51:01",

],

<p>Where is the point of the nullable() modifier if I can save records without data in not null fields?</p>

Adding WAI-ARIA attributes with JS
|
<p>At work I have been optimizing one of the sites I have helped developed for one of our clients (I can't say who) for be ADA compliant using WAI-ARIA attributes. I've been wondering if it wouldn't just be easier to create a small JS library that does things like add "role=button" to anchors I've styled to look like a button, add "tabindex=0" to elements I want to be "tabable" etc.</p>
<p>I was wondering if it is a good practice to add in WAI-ARIA attributes with JS or is that frowned upon. Some accessibility evaluation tools won't run the page's JS when evaluating it so it will think these are pain points when they are really not.</p>

<p>I have code my project using SOAP methods in NSURLConnection.Recently new version update reject it cause of ipV6 issue for ios9+</p>
<p>Now i check that for supporting ipV6 you need to convert code to standard networking APIs like NSURLSession and CFNetwork APIs provided by apple.</p>
<p>Is there alternative without converting my more then 350+ api , it will work with ipV6 . </p>

Scroll event fire delay in mobile
|
<p>I got event listener to the scroll and everything works fine with desktop browsers(when scrolling starts - the event fired straight away) and chrome browser in mobile(chrome latest version + android version 5.0), but with other mobile browsers(ff, android browser) this works differently, and after googling for some I found the reason: it's because the scroll event is not fired until the scrolling action comes to a complete stop(releasing the finger from the screen). </p>
<p>My question is there some workaround for this, perhaps some best practice, so it will fire normally(as for desktop) and without dramatically performance changes?</p>
<p>*JS solution only(no for jquery).</p>

How to find out the PredType of a dataset in HDF5 using the C++ library
|
<p>So I just found out, that if I write an <code>unsigned char</code> array into a <code>float</code> dataset in my HDF5 file the library does not complain. Therefore, I want to check before I write that the two are actually compatible. So for my <code>unsigned char</code> array I have the corresponding <code>PredType</code>. But the dataset does not offer an obvious way to get the <code>PredType</code>, if I am not mistaken.</p>
<p><strong>Question:</strong> Given a <code>H5::Dataset</code>, how do I obtain the <code>PredType</code> that was used to initialize it?</p>

how to decode the result of listenning to port 162 (Snmp Trap)?

}/* end of server infinite loop */
end();
return 0;
}
</code></pre>
<p>The code works fine now when I get traps I receive a number. Normally, I should get the trap in ASN1 (hex or bin) but I get just this: <a href="http://i.stack.imgur.com/bmXCq.png" rel="nofollow">Traplistner result</a>.
I was wondering what does the 12175440 means.

Tweepy reply to tweet in stream

<p>I have a twitter bot that responds to tweets containing a hashtag. I've been using the <code>twt = api.search(q='param')</code> to pull tweets and it's been working perfectly but I've since switched to <code>myStreamListener = MyStreamListener()
twt = tweepy.Stream(auth = api.auth, listener=myStreamListener())</code> to pull tweets in real time. this isn't working though and I don't know why. Here's my code: </p>
<pre><code>myStreamListener = MyStreamListener()
twt = tweepy.Stream(auth = api.auth, listener=myStreamListener())
twt.filter(track=['#www'], async=True)
#list of specific strings we want to omit from responses
badWords = ['xxx','yyy' ]
#list of specific strings I want to check for in tweets and reply to
genericparam = ['@zzz']
def does_contain_words(tweet, wordsToCheck):
for word in wordsToCheck:
if word in tweet:
return True
return False
for currentTweet in twt:
#if the tweet contains a good word and doesn't contain a bad word
if does_contain_words(currentTweet.text, genericparam) and not does_contain_words(currentTweet.text, badWords):
#reply to tweet
screen = currentTweet.user.screen_name
message = "@%s this is a reply" % (screen)

Why can't I pass the React unique key to onChange method
|
<p>I'm using React ES6. I'm rendering an inventory list containing unique fish elements, each fish element is mapped to a unique key and inherits props from parent component. I'd like to be able to edit the fish text and have this change feed in to the parent state.</p>
<p>My code below doesn't work as the key prop is not available to the onChange handler. Most of the documentation online recommends ReactLink for bi-directional flow but this is now deprecated so I would rather find another solution. My question is two-fold - what is the best pattern for bi-directional flow in ES6 react components and why does this code not work -specifically why can't I console log 'key' in the onChange handler.</p>
<p>Much gratitude</p>
<pre><code> render () {
var fishIds = Object.keys(this.props.fishes);
console.log("fishes are....." +fishIds);
return (
<div>
<h2>Inventory</h2>
{fishIds.map(this.renderInventory)}
<AddFishForm {...this.props}/>
<button onClick={this.props.loadSamples}> Load Sample Fishes</button>
</div>
)
}
</code></pre>
<p>Maps Keys and passes them to renderInventory</p>
<pre><code>renderInventory(key) {
var fish = this.props.fishes[key];
console.log(fish);
console.log("the key is" +key);
var nameOfFish = fish.name
return(
<div className = "fish-edit" key={key}>
<input type = "text" value ={nameOfFish} onChange={this.handleChange(key)} />
<input type = "text" value ={fish.price}/>
<select>
<option value = "unavailable">Sold out! </option>

How do I differentiate between MQTT Publish events originating from Users vs internal messages meant to broadcast only
|
<p>I am using mosquitto mqtt client.</p>
<p>For example, you have users that publish and subscribe to topics. The topic actually correlates to a REsT endpoint.</p>
<p><strong>Scenario 1 (typical pub/sub usage)</strong></p>
<ol>
<li>UserA subscribes to topic /device/123/meta</li>
<li>UserB publishes some data to topic /device/123/meta
<ul>
<li>by definition, this publish is broadcasted out to the subscribers</li>
<li>we have a script subscribed to /devices/# which knows how to save the payload for the topic /device/123/meta when it receives publish'ed data. This data is saved to the database. </li>
</ul></li>
</ol>
<p><strong>Scenario 2</strong></p>
<ol>
<li>Someone updates data /device/123/meta via a ReST interface (or a direct DB update, the key is it's not a MQTT publish).
<ul>
<li>database is updated</li>
<li>a publish message is sent to the MQTT broker so that all subscribers get the updates as a payload</li>
</ul></li>
</ol>
<p>Scenario 2 is what I'm trying to wrap my head around. This creates a nasty feedback loop. When internal messages are broadcasted out, my script to deal with publish events from users can't differentiate between publish events originating from a 3rd party user or an internal publish event only meant to broadcast out some data (with no saving of data needed).</p>
<p>How should I handle this? The MQTT message is very simplistic and I'm not finding anything I can base logic off of. I'm trying to explore using the origin somehow, but no luck this far. I realize I can write plugins, but this is quite the task for mosquitto. </p>

Fabric.js create image on Node server after loading canvas from JSON
|
<p>I've been racking my brain the last couple of days trying to figure this out. In the app I'm writing, a user can upload two images, one that overlays the other. After placing one image on top of the other, they click a button and the canvas is converted to JSON and sent to a node (express) server. The canvas is then recreated by loading the JSON data to the canvas, calling toDataURL with a multiplier of 2 and writing the data to a png file. </p>
<pre><code>router.post('/', function(req, res) {
var canvas = fabric.createCanvasForNode(600, 600);
canvas.loadFromJSON(req.body, function() {
var dataUrl = canvas.toDataURL({
format: 'png',
multiplier: 2
});
imageSrc = dataUrl.replace(/^data:image\/png;base64,/, "");
fs.writeFile('hello.png', imageSrc, 'base64', function(err) {
console.log('Error: ' + err);
});
});
</code></pre>
<p>If I don't use a multiplier (i.e. multiplier is 1), a 600x600px image is created, as expected. But when I set the multiplier to 2, to get a higher resolution image, only the top-right quarter of the produced image contains the image created from the canvas. </p>
<p><a href="http://i.stack.imgur.com/6rWBK.png" rel="nofollow">PNG image that is cutoff</a></p>
<p>I've found resources online that say this <em>was</em> an issue in previous versions of fabric and I've seen others' workarounds, but nothing seems to fix my issue. Any help, advice or resources would be greatly appreciated!</p>
<p>EDIT
Maybe I should include an example of how I pass the JSON canvas to the server:</p>
<pre><code>var json = JSON.stringify(canvas);
var http = new XMLHttpRequest();
var url = '/designer';
http.open('POST', url, true);
http.setRequestHeader('Content-type', 'application/json');
http.onreadystatechange = function () {
if (http.readyState == 4 && http.status == 200) {
alert(http.responseText);
}
};
http.send(json);

<p>I am and artist and by no means a coder and this code is not my creation. I am just seeking assistance in correcting it to suit my needs. So if someone can let me know the most simplistic adjustment I can make to this current code I would much appreciate it. I know this is not the most conventional question, I am just hoping for a little help.</p>

Laravel return records from relation table
|
<p>Hello I want to returned a list of products with the selected category.
I have two tables connected by relationship table products:</p>
<pre><code>public function up()
{
Schema::create('products', function (Blueprint $table) {
$table->increments('id');
$table->integer('user_id')->unsigned();
$table->integer('article_id')->unsigned();
$table->integer('category_id')->unsigned();
$table->string('sn');
$table->integer('quantity');
$table->date('warranty');
$table->timestamps();
});
Schema::table('products', function(Blueprint $table) {
$table->foreign('user_id')->references('id')->on('users');
$table->foreign('article_id')->references('id')->on('articles');
$table->foreign('category_id')->references('id')->on('categories');
});
}
</code></pre>
<p>and table categories:</p>
<pre><code>public function up()
{
Schema::create('categories', function (Blueprint $table) {
$table->increments('id');
$table->string('category_name');
$table->timestamps();
});
}
</code></pre>
<p>product model:</p>
<pre><code>public function user(){
return $this->belongsTo('App\User');
}
public function article(){
return $this->belongsTo('App\Article');
}
public function category(){
return $this->belongsTo('App\Category');
}
</code></pre>
<p>And category model:</p>
<pre><code>public function products(){
return $this->hasMany('App\Product')->withTimestamps();
}
</code></pre>
<p>I write query SQL in phpmyadmin:</p>
<pre><code>SELECT
products.id,
products.user_id,
articles.article_name,
categories.category_name,
products.sn,
products.quantity,
products.warranty,
products.created_at,
products.updated_at,
SUM(quantity) AS ilosc
FROM
products
LEFT JOIN
categories ON products.category_id = categories.id
LEFT JOIN
articles ON products.article_id = articles.id
GROUP BY articles.article_name
ORDER BY id;
</code></pre>
<p>This query works on phpmyadmin but I want write metohod in Laravel. <strong>How can I return a list of products assigned to the selected category ??</strong> I would add that the selected category is passed in the method show by ID CATEGORY:</p>
<pre><code>public function show($id){
$categories = Category::find($id);
return view('categories.showcategory', compact('categories'));
}
</code></pre>
<p>I do not want a solution, only hints how I can do it. I found this theme <a href="http://I%20found%20this,%20but%20still%20do%20not%20know%20how%20to%20do%20it">enter link description here</a>, but still I do not know how to do it ;)</p>
<p>I convert query SQL to query laravel i file CategoriesController:</p>
<pre><code>public function show($id){
$categories = Category::find($id);
$productsList = DB::table('products')->select('products.id,
products.user_id,
articles.article_name,
categories.category_name,
products.sn,
products.quantity,
products.warranty,
products.created_at,
products.updated_at,
SUM(quantity) AS ilosc')->from('products')->where('id' , '=' , $categories->id)->leftJoin('categories', 'products.category_id', '=', 'categories.id')->leftJoin('articles', 'products.article_id', '=', 'articles.id')->groupBy('articles.article_name')->orderBy('id')->get();
return view('categories.showcategory', compact('categories', 'productsList'));
}
</code></pre>
<p>But Laravel returned error:</p>
<blockquote>
<p>SQLSTATE[42S22]: Column not found: 1054 Unknown column 'products.id, '
in 'field list' (SQL: select <code>products</code>.<code>id,</code> as `` from <code>products</code>
left join <code>categories</code> on <code>products</code>.<code>category_id</code> = <code>categories</code>.<code>id</code>
left join <code>articles</code> on <code>products</code>.<code>article_id</code> = <code>articles</code>.<code>id</code>
where <code>id</code> = 1 group by <code>articles</code>.<code>article_name</code> order by <code>id</code> asc)</p>
</blockquote>
<p>with the help of swatkins I wrote method:</p>
<pre><code>public function show($id){
$categories = Category::find($id);
$productsList = Category::with(['products' => function ($query) {
$query->where('category_id', 20);
}])->get();
return view('categories.showcategory', compact('categories', 'productsList'));
}
</code></pre>
<p>Laravel returns correctly Products with selected category, but only when I write ID category. In this method ID category is equal to 20. </p>
<p>$query->where('category_id', <strong>20</strong>);</p>
<p><strong>How can I dynamically pass the value of GET category_id ??</strong></p>

Where is the (OSX) path for an updated version of the Android NDK?
|
<p>Where is the path for an updated version of the Android NDK? I'm on Mac OSX 10.11.5 (El Capitan)</p>
<p>I used android-ndk-r10e for a good while, but just updated to the latest version of the NDK using Android Studio's SDK Manager. I watched its progress and noted that it was version r12 and also the root dir where it was installing, but when I went to look for it I can't find anything that looks like my original installation.</p>
<p>When I originally installed r10e, the folder name that it installed into was/is:</p>
<pre><code>/android-ndk-r10e
</code></pre>
<p>Below is my CHANGELOG.md that I found in the ndk-bundle folder of the dir where the update seemed to be installed. Seems clear that r12b was installed, but where? Shouldn't there be an "android-ndk-r12b" folder somewhere?</p>
<pre><code>Changelog
=========
Report issues to [GitHub].
[GitHub]: https://github.com/android-ndk/ndk/issues
Announcements
-------------
* `ndk-build` will default to using Clang in r13. GCC will be removed in a
later release.
* `make-standalone-toolchain.sh` will be removed in r13. Make sure
`make_standalone_toolchain.py` suits your needs.
r12b
----
* `ndk-gdb.py` has been fixed: https://github.com/android-ndk/ndk/issues/118
* NdkCameraMetadataTags.h has been updated to no longer contain the invalid
enum value.
* A bug in `ndk-build` that resulting in spurious warnings for static libraries
using libc++ has been fixed:
https://android-review.googlesource.com/#/c/238146/
* The OpenSLES headers have been updated for android-24.
NDK
---
* Removed support for the armeabi-v7a-hard ABI. See the explanation in the
[documentation](docs/HardFloatAbi.md).
* Removed all sysroots for pre-GB platform levels. We dropped support for them
in r11, but neglected to actually remove them.
* Exception handling when using `c++_shared` on ARM32 now mostly works (see
[Known Issues](#known-issues)). The unwinder will now be linked into each
linked object rather than into libc++ itself.
* Default compiler flags have been pruned:
https://github.com/android-ndk/ndk/issues/27.
* Full changes here: https://android-review.googlesource.com/#/c/207721/5.
* Added a Python implementation of standalone toolchains:
`build/tools/make_standalone_toolchain.py`.
* Windows users: you no longer need Cygwin to use this feature.
* We'll be removing the bash flavor in r13, so test the new one now.
* `-fno-limit-debug-info` has been enabled by default for Clang debug builds.
This should improve debugability with LLDB.
* `--build-id` is now enabled by default.
* This will be shown in native crash reports so you can easily identify
which version of your code was running.
* `NDK_USE_CYGPATH` should no longer cause problems with libgcc:
http://b.android.com/195486.
* `-Wl,--warn-shared-textrel` and`-Wl,--fatal-warnings` are now enabled by
default. If you have shared text relocations, your app will not load on
Marshmallow or later (and have never been allowed for 64-bit apps).
* Precompiled headers should work better:
https://github.com/android-ndk/ndk/issues/14 and
https://github.com/android-ndk/ndk/issues/16.
* Unreachable ARM (non-thumb) STL libraries have been removed.
* Added Vulkan support to android-24.
* Added Choreographer API to android-24.
* Added `libcamera2` APIs for devices with
`INFO_SUPPORTED_HARDWARE_LEVEL_LIMITED` or above (see [Camera
Characteristics]).
[Camera Characteristics]: https://developer.android.com/reference/android/hardware/camera2/CameraCharacteristics.html#INFO_SUPPORTED_HARDWARE_LEVEL
Clang
-----
* Clang has been updated to 3.8svn (r256229, build 2812033).
* Note that Clang packaged in the Windows 64-bit NDK is actually 32-bit.
* `__thread` should work for real this time.
GCC
---
* Synchronized with the ChromeOS GCC @ `google/gcc-4_9` r227810.
* Backported coverage sanitizer patch from ToT (r231296).
* Fixed libatomic to not use ifuncs:
https://github.com/android-ndk/ndk/issues/31.
Binutils
--------
* "Erratum 843419 found and fixed" info messages are silenced.
* Introduced option '--long-plt' to fix internal linker error when linking huge
arm32 binaries.
* Fixed wrong run time stubs for AArch64. This was causing jump addresses to be
calculated incorrectly for very large DSOs.
* Introduced default option '--no-apply-dynamic' to work around a dynamic
linker bug for earlier Android releases.
* NDK r11 KI for `dynamic_cast` not working with Clang, x86, `stlport_static`
and optimization has been fixed.
GDB
---
* Updated to GDB 7.11: https://www.gnu.org/software/gdb/news/.
* Some bugfixes for `ndk-gdb.py`.
Known Issues
------------
* This is not intended to be a comprehensive list of all outstanding bugs.
* x86 ASAN still does not work. See discussion on
https://android-review.googlesource.com/#/c/186276/
* Exception unwinding with `c++_shared` still does not work for ARM on
Gingerbread or Ice Cream Sandwich.
* Bionic headers and libraries for Marshmallow and N are not yet exposed
despite the presence of android-24. Those platforms are still the Lollipop
headers and libraries (not a regression from r11).
* RenderScript tools are not present (not a regression from r11):
https://github.com/android-ndk/ndk/issues/7.

"ERROR ITMS-90029" Storyboard file LaunchScreen~ipad.storyboardc was not found
|
<p>I have a Xamarin Forms project which debugs fine, builds fine on both iOS and Android. However when building the IPA for iOS, I try to use the Application Loader to submit the IPA and it reveals the error below:</p>
<p>I am getting the error "ERROR ITMS-90029" Storyboard file 'LaunchScreen~ipad.storyboardc' was not found. Please ensure the specified file is included in the bundle with any required device modifiers appended to the filename.</p>
<p>I have configured the LaunchScreen.storyboard file to "Builds for" iOS 8.0 and later.</p>
<p>As it's a Xamarin Forms project, I only have one storyboard file, LaunchScreen.storyboard . In my Info.plist, my Deployment Info is:</p>
<ul>
<li><p>Deployment Target: 7.0</p>
<p>Devices: Universal</p>
<p>Main Screen: LaunchScreen</p>
<p>Device Orientations: Portrait, Upside Down</p>
<p>Hide Status bar: no</p>
<p>Requires full screen: no</p></li>
</ul>
<p>Launch Images:</p>
<ul>
<li>Launch Screen: LaunchScreen</li>
</ul>
<p>This is such an absolute nightmare. I have tried every combination of settings, rebuilding, cleaning, you name it. They all produce IPA successfully, and they all error out with the same error. I cannot figure it out.</p>

Why is @override annotation optional?
|
<p>I understand definition of an <a href="https://api.dartlang.org/stable/1.17.1/dart-core/override-constant.html" rel="noreferrer">@override</a> annotation.</p>
<p>But, why is the usage of the annotation optional? </p>

Way to implement SSO for web and desktop applications
|
<p>I am reading alot about federated identity management and technologies like SAML, which can be used for implementing SSO for web applications, and Kerberos, which can be used for implementing SSO für desktop applications. </p>
<p>This is how I understood it so far. If we have the case, that we want to have SSO for a set of web applications and desktop applications, what are the technologies that are available for that? Do I have to combine SAML and Kerberos or is there another technology that fits better?</p>

No 'Access-Control-Allow-Origin' error with Laravel and React
|
<p>I am sending a request from my react app <code>localhost:8080</code> to my lumen api <code>localhost:8000</code> to retrieve json data.</p>
<p>This is my <code>routes.php</code> in lumen: <code>$app->get('list', 'ArticleController@listAll');</code></p>
<p>And this is my <code>ArticleController.php</code> in lumen:</p>
<pre><code><?php
namespace App\Http\Controllers;
use Response;
use Illuminate\Support\Facades\Input;
use App\Article as Article;
class ArticleController extends Controller
{
public function listAll(){
$articles = Article::all();
return response()
->json($articles)
->setCallback(Input::get('callback'));
}
}
</code></pre>
<p>Because I get that error for cross domain fetch, I am trying to use jsonp, but for some reason it's still not working.</p>
<p>This is my code in React:</p>
<pre><code>componentWillMount(){
fetch('http://localhost:8000/list?callback=asdf', {

Write tests in phpunit for Laravel json API
|
<p>I have trouble in create tests for my API in laravel. Here how look my routes.php:</p>
<pre><code>Route::group(['middleware' =>'api', 'prefix' => '/api/v1', 'namespace' => 'Api\V1'], function () {
Route::post('/login', 'Auth\AuthController@postLogin');
Route::group(['middleware' =>'jwt.auth'], function () {
Route::post('/projects', 'ProjectsController@postProjects');
...
});
});
</code></pre>
<p>My <code>ProjectsController@postProjects</code> looks like this (I test it by POSTman and it works fine):</p>
<pre><code>public function postProjects() {
$project = new Project;
$project->fill(request()->all());
$project->user_id = Auth::user()->id;
$project->save();
return ['project_id' => $project->id];

<p>I write my own middelware for authentication using JWT cookie which is described in details <a href="https://stackoverflow.com/questions/38415851/how-to-make-jwt-cookie-authentication-in-laravel/38416675#38416675">here</a>. But in my test, I try to turn off middelware (<code>use WithoutMiddleware</code>)and act as logged user (<code>actingAs($user)</code> - I have user (id=1) in my DB). My test looks like that (I wrote it using <a href="https://laravel.com/docs/5.2/testing#testing-json-apis" rel="nofollow noreferrer">this documentation</a>):</p>
<pre><code><?php

Rails 5, Devise, Omniauth, Twitter
|
<p>I know this has been asked many times, but the answers are never fully acceptable to me.</p>
<p>So I am following <a href="http://railscasts.com/episodes/235-devise-and-omniauth-revised?autoplay=true">Ryan Bates' Railscast</a> about this topic, and mixing that with the official <a href="https://github.com/plataformatec/devise/wiki/OmniAuth:-Overview">Devise Omniauth guide</a> (that is based on FB), but I am just not getting it to work like I expect, so I would love some help. </p>
<p>I have a <code>Users::OmniauthCallbacksController</code> that looks like this:</p>
<pre><code>class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController
def all
@user = User.from_omniauth(request.env["omniauth.auth"])
if @user.persisted?
sign_in_and_redirect root_path, :event => :authentication #this will throw if @user is not activated
set_flash_message(:notice, :success, :kind => "Twitter") if is_navigational_format?
else
session["devise.twitter_data"] = request.env["omniauth.auth"].except("extra")
flash[:notice] = flash[:notice].to_a.concat resource.errors.full_messages
redirect_to new_user_registration_url
end
end
alias_method :twitter, :all
def failure
redirect_to root_path
end
end
</code></pre>
<p>Then I also have two methods on my <code>User.rb</code></p>
<pre><code> def self.from_omniauth(auth)
where(provider: auth.provider, uid: auth.uid).first_or_create do |user|
user.update(
email: auth.info.email,
password: Devise.friendly_token[0,20],
username: auth.info.nickname,
remote_avatar_url: auth.info.image,
token: auth.credentials.token,
secret: auth.credentials.secret
)
end
end
def self.new_with_session(params, session)
super.tap do |user|
if data = session["devise.twitter_data"]
# user.attributes = params
user.update(
email: params[:email],
password: Devise.friendly_token[0,20],
username: data["info"]["nickname"],
remote_avatar_url: data["info"]["image"],
token: data["credentials"]["token"],
secret: data["credentials"]["secret"]
)
end
end
end
</code></pre>
<p>I run into a variety of problems. The most immediate is because I am setting the password, the user doesn't know the password when they try to login (and I don't auto sign them in upon confirmation).</p>
<p>But if I don't set the password, it doesn't ask them to set the password...so that's kinda weird too.</p>
<p>These are my devise settings on my <code>User</code> model:</p>
<pre><code> devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable,
:confirmable, :omniauthable, :omniauth_providers => [:twitter]
validates :username,
presence: true,
uniqueness: {
case_sensitive: false
}
validate :validate_username
def validate_username
if User.where(email: username).exists?
errors.add(:username, :invalid)
end
end
</code></pre>
<p>So my question is this, when someone signs up via Twitter, do they need to enter a password? I automatically send them to the <code>registration/new.html.erb</code> anyway because Twitter doesn't return an email value. But I am trying to just get the process working first, before optimizing it.</p>
<p>How do I deal with the password issue?</p>
<p><strong>Edit 1</strong></p>
<p>For more clarity, I will have to deal with this <code>password_required</code> issue regardless of the OAuth provider.</p>
<p>So how do I override that requirement for all OAuth providers?</p>

Getting a reference to NgMap inside Angular controller
|
<p>This syntax taken from ngMap <a href="https://github.com/allenhwkim/angularjs-google-maps" rel="nofollow">https://github.com/allenhwkim/angularjs-google-maps</a> works fine:</p>
<pre><code> angular
.module('trails')
.controller('MyController', function (NgMap) {
NgMap.getMap().then(function (map) {
console.log(map.getCenter());
console.log('markers', map.markers);
console.log('shapes', map.shapes);
});
});
</code></pre>
<p>But the syntax I use for declaring controllers is different and I get the error: </p>
<blockquote>
<p>angular.js:13642 TypeError: Cannot read property 'getMap' of undefined</p>
</blockquote>
<p>It fails on the line as further below:</p>
<blockquote>
<p>NgMap.getMap().then(function (map) {</p>
</blockquote>
<p>The controller is declared as:</p>
<pre><code> angular
.module('trails')
.controller('ActivityDetailsController', [
'$mdSidenav', '$mdBottomSheet', '$timeout', '$log', '$http', '$location', '$routeParams',
ActivityDetailsController
]);
function ActivityDetailsController($mdSidenav, $mdBottomSheet, $timeout, $log, $http, $location, $routeParams, NgMap) {
var self = this;
$http.get('/activity/detailStats/' + $routeParams.id, {
params: { max: "1000" }
})
.success(function (data) {
self.stats = data.stats;
// Zoom to fit
var bounds = new google.maps.LatLngBounds();
for (var i = 0; i < self.stats.activityTrackPoints.length; i++) {
var latlng = new google.maps.LatLng(self.stats.activityTrackPoints[i][0], self.stats.activityTrackPoints[i][1]);
bounds.extend(latlng);
}
NgMap.getMap().then(function (map) {
map.setCenter(bounds.getCenter());
map.fitBounds(bounds);
});
})
.error(function (data, status) {
console.error('https error', status, data);
})
.finally(function () {
});
</code></pre>
<p>I have tried adding the NgMap in other obvious places, such as:</p>
<pre><code>...'$routeParams', NgMap,
ActivityDetailsController...
</code></pre>
<p>or doing a ActivityDetailsController.$inject = NgMap before the controller declaration etc but it gives a similar error to above in that NgMap cannot be referenced.</p>
<p>Edit: ngMap dependency was setup in another file similar to the answers already. Sorry I didn't put this earlier, but the above code that works and doesn't work are in the same place together so I thought it seemed ok to leave that out originally.</p>
<pre><code>var app = angular
.module('trails', ['ngMaterial', 'md.data.table', 'ngRoute', 'ngMap'])
</code></pre>
<p>I'm not sure if this is to do with the way I am incorrectly trying to inject NgMap using this controller declaration or something in NgMap...or most likely my inexperience with either framework!</p>

How to write a dataset of Null Terminated Fixed Length Strings with h5py
|
<p>I have an example in C++ that I'm trying to reproduce using h5py, but it is not working as expected. I'm getting null padded strings with h5py where I expect null terminated strings.</p>
<p>Here is my C++ driver...</p>
<p><code>main.cpp</code></p>
<pre><code>#include <hdf5.h>
int main(void) {
auto file = H5Fcreate("test-c.h5", H5F_ACC_TRUNC,
H5P_DEFAULT, H5P_DEFAULT);
char strings[5][64] = {
"please work 0",
"please work 1",
"please work 2",
"please work 3",
"please work 4"};
auto H5T_C_S1_64 = H5Tcopy (H5T_C_S1);
H5Tset_size(H5T_C_S1_64, 64);
hsize_t dims[1] = {5};
auto dataspace = H5Screate_simple(1, dims, NULL);
auto dataset = H5Dcreate(file, "test dataset", H5T_C_S1_64, dataspace,
H5P_DEFAULT, H5P_DEFAULT, H5P_DEFAULT);
H5Dwrite (dataset, H5T_C_S1_64, H5S_ALL, H5S_ALL, H5P_DEFAULT, strings);
H5Dclose(dataset);
H5Sclose(dataspace);
H5Tclose(H5T_C_S1_64);
H5Fclose(file);
return 0;
}
</code></pre>
<p>Which I build with the following SCons script.</p>
<p><code>SConstruct</code></p>
<pre><code>env = Environment()
env.Append(LIBS=['hdf5'],
CPPFLAGS=['-std=c++11'])
env.Program('writeh5', 'main.cpp')
</code></pre>
<p>And here is my python script that I'm trying to get to write out the same hdf5 file with.</p>
<p><code>main.py</code></p>
<pre><code>import h5py
hdf5 = h5py.File('test-p.h5', 'w')
H5T_C_S1_64 = h5py.h5t.C_S1.copy()
H5T_C_S1_64.set_size(64)
print "Null Terminated String: %s" % (
H5T_C_S1_64.get_strpad() == h5py.h5t.STR_NULLTERM)
dataset = hdf5.create_dataset('test dataset', (5,),
data=['please work %s' % n for n in xrange(5)],
dtype=H5T_C_S1_64)
hdf5.close()
</code></pre>
<p>I'm using python v2.7.11, and I have tried this with h5py v2.5.0, and v2.6.0, with the following same results.</p>
<pre><code>>> python --version
Python 2.7.11

<p>As you can see from the output above, I am still ending up with null padded fixed length strings when using h5py, even though I am specifying I want null terminated fixed length strings.</p>
<p>So how do I modify my python script to end up with null terminated fixed length strings in the dataset? If it is a bug in h5py, are there any workarounds?</p>
<p>Thanks in advance for any help.</p>

<p>I want the second rect element with class insider to stick to the top right of the main SVG element. I tried <strong>float;right</strong> and <strong>top:0; right:0;</strong> in CSS but that doesn't makes it move.

<p>How can I make it stick to the top right corner when the parent (SVG) is resized?</p>

Android light and fast way to implement data storage from Api Rest service
|
<p>I'd have to implement a simple app that retrieves some data from Api Rest service through JSON and save them to internal data storage.</p>
<p>Until now, I'm using AsynTask custom class for each call but it seems a complicated and slow process to retrieve json, check, parse and save it to storage ( I'm usic DBHelper with an SQLLite DB ).</p>
<p>I don't need to manage a large amount of data, I need to manage events with some strings, an image url, and some dates.
The important is having a fast process to load/update/storage/retrieve information from API Rest Service to android internal storage.</p>
<p>What is the best solution to implement it?</p>
<p>Thank you guys</p>

VHDL: How to use 2 regular 4-Bit adders to design an 8-Bit BCD counter?
|
<p>Unlike most counters that i have viewed on this website, my BCD counter requires the use of two 4-Bit adders in order to make 1 8-Bit BCD counter. What I have done so far is design a regular full adder, used that to design a regular 4 bit adder.</p>
<p>This is my code so far:</p>
<pre><code>library ieee;
use ieee.std_logic_1164.all;
entity adder8b_custom is
port(
X: in std_logic_vector( 7 downto 0);
Y: in std_logic_vector (7 downto 0);
S: out std_logic_vector (7 downto 0));
end adder8b_custom;
architecture adder8b_custom of adder8b_custom is
component adder4b
port ( X : in STD_LOGIC_VECTOR (3 downto 0);
Y : in STD_LOGIC_vector (3 downto 0);
C0: in STD_LOGIC;
S : out STD_LOGIC_VECTOR (3 downto 0);
C4: out STD_LOGIC);
end component;
signal s1:std_logic_vector ( 7 downto 0); --for addition
signal s2:std_logic_vector ( 7 downto 0); --for subtraction
signal s3, s4, s5, s6: std_logic_vector (3 downto 0);--placeholders
signal i, j, k, l: std_logic;
begin
u1: adder4b port map (X => X (3 downto 0), Y => "0001",c0=>'0', S => s3 (3 downto 0), c4=>i);
s1(3 downto 0) <=s3(3 downto 0) when s3 (3 downto 0) /="1010"
else "0000";
s<=s1;
--u2: adder4b port map (X => X (7 downto 4), Y => "0001" ,c0 => i, S => s4 (3 downto 0), c4=>j);
--s1( 7 downto 4) <= s4( 3 downto 0) when s4( 3 downto 0) /= "1010"
--else "0000";
--s(7 downto 4)<= s1;
end;

<p>As you can see, everything after the signals is messed up and i do know know how to fix it.</p>
<p>I appreciate all input.</p>

Trigger function on click for hangman game
|
<p>I'm new to JavaScript and have been trying to code up this Hangman game, but am running into issues. What I have to far is the following: </p>
<p>My HTML: </p>
<pre><code><div class="col-md-4">
<div id="placeHolder">_ _ _ _ _ _</div>
<div id="gamestatus"></div>
<input type="text" size="1" id="letterGuess" maxlength="1">
<button id="button" onclick="guess()">Press to start</button>
</div>
</code></pre>
<p>My JavaScript:</p>
<pre><code>var dictionary = ['music', 'mountain', 'forest', 'florida', 'sweden', 'golf'];
var wordUsed, input, placeHolder;
function startGame()
{
placeHolder = "";
var totalGuesses = 10;
wordUsed = dictionary[Math.floor(Math.random() * dictionary.length)];
console.log(wordUsed);
var buttonText = document.getElementById("button").innerHTML = "Guess";
for(var i = 0; i < wordUsed.length; i++)
{
placeHolder += "_ ";
}
document.getElementById("placeHolder").innerHTML = placeHolder;
document.getElementById("gamestatus").innerHTML = "Game is in progress.";
}
function guess()
{
var correctGuess = false;
var ip = document.getElementById("letterGuess");
input = ip.value;
for(var i = 0; i < wordUsed.length; i++)
{
if(input == wordUsed.substring(i, i + 1))
{
correctGuess = true;
placeHolder = placeHolder.substring(0, i) + input + placeHolder.substring(i + 1, placeHolder.length + 1);
document.getElementById("placeHolder").innerHTML = placeHolder;
}
}
if(!correctGuess)
{
totalGuesses--;
}
if(placeHolder == wordUsed)
{
alert("You WIN!");
}
if(totalGuesses == 0)
{
alert("You LOSE!")
startGame();
}
}
startGame();
document.getElementById("button").onclick = guess;
</code></pre>
<p>So the code is correctly selecting a word and placing the correct amount of underscores in places of the letters; but nothing happens when I run my code. I might've over-looked something really simple and would really appreciate if someone could point out what is wrong with the code/logic. </p>
<p>Also, any other tips on how to improve the code/logic will be appreciated! Thanks. </p>

Can't connect to AWS PostgreSQL instance

<p>I'm trying to login to a newly created PostgreSQL DB instance created using AWS's RDS service.</p>
<p>This is the command I've been running (I've redacted the sensitive info): </p>
<pre><code>psql \
--host=my_aws_end_point \
--port=5432 \
--username the_username \
--password the_password \
--dbname=ebdb
</code></pre>
<p>For the security group associated with the instance I have allowed the following inbound connections:</p>
<pre><code>PostgreSQL TCP 5432
PostgreSQL TCP 5432 My_IP
PostgreSQL TCP 5432 0.0.0.0/0 All traffic
All All 0.0.0.0/0 Custom TCP Rule
TCP 0 0.0.0.0/0
</code></pre>
<p>This is the error I'm getting:</p>
<pre><code>psql: could not connect to server: Operation timed out
Is the server running on host "aws_db_enpoint..." (IP...) and accepting
TCP/IP connections on port 5432?
</code></pre>
<p>I've also tried running other commands but have ran into the same issue.</p>
<p>The one command that does seem to work is the following:</p>
<pre><code>pg_restore -v -h 'aws_db_enpoint' --port 5432 -U user_name dump.sql

<p>Any help would be much appreciated!</p>

How to index Dynamodb streams data in Amazon Elasticsearch Services via AWS Lambda?

<p>I followed step by step <a href="https://aws.amazon.com/fr/blogs/compute/indexing-amazon-dynamodb-content-with-amazon-elasticsearch-service-using-aws-lambda/" rel="nofollow noreferrer">this tutorial</a> but when I'm arriving at the "Testing the result" step, I don't see my table name in the indices time as "all products" is showed in the example.</p>
<p>So it means my dynamodb table is not indexed in my Amazon ES domain.</p>
<p>I set all authorizations and configured lambda just as in the example.</p>
<p>Now I just don't know how to do for triggering my dynamodb streams in AWS ES.</p>

<p><strong>Game:</strong>
I have 2 players multiplayer game where each player can shoot.</p>
<p><strong>Problem:</strong></p>
<p>Code 1 makes both players shoot (in the host game only) when host player press spacebar. The client player cannot shoot from the client's game. </p>
<p>Note: the <code>if (Input.GetKeyDown (KeyCode.Space))</code> is inside the CmdShoot method.</p>

How to set clientUserId for a Recipient in DocuSign using the REST API?
|
<p>I'm trying to create a RecipientView to send through an app to the recipients of envelopes that are created. With DocuSign's newer API, this requires a <code>userName</code> which is entered by the person who creates the document needed to be signed, an <code>email</code> which is just the email of the recipient, and a <code>clientUserId</code> which is a sender generated string value that authenticates the recipient as an embedded signer so that a RecipientView can be generated to host the signing ceremony.</p>
<p>DocuSign documentation references that I need to set <code>clientUserId</code>, but it doesn't mention <strong>how</strong> to to do this other than when the envelope is created through the API. However, in this scenario, envelopes will be created by DocuSign Admin clients through the templates on the actual web interface, and <strong>not</strong> through the API. </p>
<p>My code to generate the RecipientView is all set up here:</p>
<pre><code>$url = "https://demo.docusign.net/restapi/v2/accounts/$account_id/envelopes/$envelope_id/views/recipient";
$body = array("returnUrl" => "http://www.docusign.com/devcenter",
"authenticationMethod" => "None",
"email" => "$email",
"userName" => "$name",
"recipientId" => "$recipientId",
"clientUserId" => "1000"
);
$body_string = json_encode($body);
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HTTPHEADER, array(
'Accept: application/json',
'Content-Type: application/json',
'Content-Length: '.strlen($body_string),
"Authorization: Bearer $access_token"
));
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $body_string);
$json_response = curl_exec($curl);
$status = curl_getinfo($curl, CURLINFO_HTTP_CODE);
if ($status != 201){
die('Could not connect to end point: '.mysqli_error($conn));
}
$response = json_decode($json_response, true);
$url = $response["url"];
</code></pre>
<p>This code <strong>does</strong> work when the embedded signer is the Admin account, but not when the envelope is sent to an actual recipient. The return JSON from DocuSign after this request should be:</p>
<pre><code>{
"url": "example.example.com"
}
</code></pre>
<p>However, the return I get for recipients that are not the Admin of the DocuSign account is:</p>
<pre><code>{
"errorCode": "UNKNOWN_ENVELOPE_RECIPIENT",
"message": "The recipient you have identified is not a valid recipient of the
specified envelope."
}
</code></pre>
<p>I believe not setting <code>clientUserId</code> is the reason behind this, since the <a href="https://www.docusign.com/developer-center/explore/features/embedding-docusign" rel="nofollow">documentation</a> says I need to set <code>clientUserId</code> and not just create a value when making the call. How do I set a recipient's <code>clientUserId</code> via the REST API?</p>
<p><strong>UPDATE:</strong> Within this scenario, I will not be the one creating and sending envelopes. That will be done by the clients I have through my app, and the large majority of them will most likely use the web interface to do this, not the API. I do have access to all information regarding the Admin account for each client, including the Integrator Key, Access Tokens, Envelope IDs, Account IDs, etc.</p>

Dexie: difference bulkPut and BulkAdd
|
<p>I have checked <a href="https://github.com/dfahlander/Dexie.js/wiki/WriteableTable" rel="nofollow">the Documentation</a>, but there seems to be no difference between using bulkPut and bulkAdd.</p>
<p>Yet I noticed that when I try to use bulkAdd with a list of events including one that I previously deleted, it does not add this event. If I use bulkPut it does add the event.</p>
<p>I would like to have a better understanding of the difference between this two methods.</p>
<p>Thanks</p>

Rendering html to pdf
|
<p>I am new to Laravel. I want to convert my HTML page into PDF therefore I am using:</p>
<p><a href="https://github.com/barryvdh/laravel-snappy" rel="nofollow">https://github.com/barryvdh/laravel-snappy</a></p>
<p>Now from my controller I am using the following code:</p>
<pre><code>$data = $this->getdata();
$html = view('myview', [ 'data' => $data] )->render();
$pdf = \App::make('snappy.pdf.wrapper');
$pdf->loadHtml($html);
return $pdf->inline();
</code></pre>
<p>When I dump or return the <code>$html</code> variable, it's giving the desire view on the browser but when I convert it its not giving that output. My HTML page is also using Bootstrap but I think after rendering its just a normal HTML string.
Can anyone tell what I am missing here?</p>
<p>I have also tried <code>$pdf->loadView()</code> but it's not working.</p>

How can I turn all my 'perform_later's into 'perform_now's locally?
|
<p>I'm working on a product that calls of <code>perform_later</code> jobs. This works for our product in production because we have a series of workers who will run all the jobs. </p>
<p>But, when I'm using the app locally, I don't have access to these workers, and I'd like to change all the <code>perform_later</code>s into <code>perform_now</code>s <em>only when</em> I use the app locally. </p>
<p>What's the best way to do this? One idea I had was to add something in my <code>env</code> file that would add a variable to make all <code>perform_later</code>s into <code>perform_now</code>s -- but I'm not sure what a flag or variable like that would look like. </p>
<p>Ideas?</p>

How to select ALL UICollectionView cells like in the iOS Photos app using Swift?
|
<p>I can't seem to get this to work for me and I haven't found any other answers to similar questions that work. </p>
<p>I am working with Swift and need to know how to be able to have a "Select All" button in my app select all visible & non-visible cells just like the stock Photos app on iOS.</p>
<p>My app is dealing with photos too, and so each cell has two UIImageViews, one that is the photo in question, and another that is a hidden UIImageView that appears upon selection of an image (it is just a check mark).</p>
<p>The code I've been using (which won't work) is this:</p>
<pre><code> for cell in self.collectionView.visibleCells() as! [ImageCell]{
if cell.checkMark.hidden{
cell.checkMark.hidden = false
}
else{
cell.checkMark.hidden = true
}
}

PHP- get previous rows value

<p>I have a database that contains the following:</p>
<pre><code>ID | value
1 | Hello
14 | Potato
34 | Henry

<p>The information is echoed using the following foreach:</p>
<pre><code>foreach($db->query("SELECT * FROM table") as $X){
echo $X['ID'];
echo $X['value']; }

<p>Is there a way to get the ID from the previous row in the table as a variable?
So as the result looks something along the lines of this:</p>
<pre><code>echo "Current ID: ".$X['ID'];
echo "Current value: ".$X['value'];
echo "Previous value: ".$PreviousValue;

<p>gives</p>

Powershell Remove-Item locking file after script finishes
|
<p>I am creating a basic script that should access my NetApp, run two commands and output the results to a csv file, and then email that csv file to me. Finally, the file should be deleted.</p>
<p>From what I have learned while reading, shouldn't powershell wait until the previous step was completed and then automatically close the file after it was sent? I can still delete the file up until the Send-MailMessage command. The very next command is to delete the file, and the error is generated. This also happens if I highlight each line in the script and run them manually, waiting several minutes between commands. The only way I have found, so far, to unlock the file is to close Powershell.</p>
<p>How can I force Powershell to delete this open file? No other process is using it, I have received the email, and am no longer interested in keeping the file. I would prefer not to use a third party tool to do this</p>
<p>I am getting an error when I try to delete the file.</p>
<p>The delete command:</p>
<pre><code>If (Test-Path $attachment){
Remove-Item $attachment -Force
}
</code></pre>
<p>The error:</p>
<pre><code>Remove-Item : Cannot remove item C:\perfstat\NcVol.csv: The process cannot access the file 'C:\perfstat\NcVol.csv' because it is being used by another process.
At line:1 char:1

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : WriteError: (C:\perfstat\NcVol.csv:FileInfo) [Remove-Item], IOException

<p>Other bits:</p>

Inserting into SQLite database with parameters
|
<p>I am building a cross-platform app using AngularJS, Monaca and OnsenUI.</p>
<p>I have implemented a SQLite database to save data to be able to work offline. My implementation is based on the answer found <a href="https://stackoverflow.com/questions/26604952/a-simple-cordova-android-example-including-sqlite-read-write-and-search">HERE</a></p>
<p>I have a view where the user can select any number of options and those option values should then be saved to the SQLite database. Each option value can be saved to the same database table or separate tables - depending on the option value selected.</p>
<p>With this I am trying to refactor my insert statement to make it more efficient as it may be called many times. In my <strong><em>app.js</em></strong> controller I have a function that checks which option value was selected in the view, and then calls the <em>goInsert()</em> function that inserts the selected option value into the SQLite Database. Below is a sample of my function.</p>
<pre><code>$scope.selectedIDOne = ""; // Variable to hold selected options value
$scope.changedValue = function (item, identifier) // item = selected option value; identifier = identifies table name to insert into
{
switch (identifier)
{
case "Square":
$scope.selectedIDOne = item;
db.transaction(goInsert(identifier), errorCB, successCB); // Error on refactored goInsert(identifier) function trying to pass identifier
break;
default:
// TODO
}
}
</code></pre>
<p>Then I try the following in my goInsert() function.</p>
<pre><code>function goInsert(identifier) // Error here
{
switch (identifier)
{
case "Square":
db.transaction(insertSquareDB, errorCB, successCB);
break;
}
}
function insertSquareDB(tx)
{
tx.executeSql('INSERT OR IGNORE INTO tb_square (square_id) VALUES ("' + $scope.selectedIDOne + '" )');
}
</code></pre>
<p>When I run the code I get an error where indicated but the value is nonetheless inserted int the database. The error is thrown at the goInsert(identifier) function call. The error is: </p>
<p>TypeError: Failed to execute 'Transaction' on 'Database'. The callback provided as parameter 1 is not a function.</p>
<p>How can I implement this solution please? Or is there a better way? I would also ideally not like to create multiple <em>insertSquareDB(tx)</em> functions e.g. insertCircleDB(tx), insertROundDB(tx) etc. Is there a way I can have 1 function defined that inserts values dynamically e.g. (hypothetical)</p>
<pre><code>function insertSquareDB(tx, tableName, columnName, optionValues)
{
tx.executeSql('INSERT OR IGNORE INTO tableName (columnName) VALUES ("' + optionValues + '" )');
}
</code></pre>

Updates in my React application aren't taken into account Webpack dev server
|
<p>I'm trying to set up an environment for my React application using Webpack and Babel. I use JSX to implement components and I would like to leverage live reload.</p>
<p>Here is my <code>package.json</code> file:</p>
<pre><code>{
(...)
"scripts": {
"start": "webpack-dev-server --hot --inline"
},
"dependencies": {
"babel-loader": "^6.2.4",
"babel-preset-es2015": "^6.9.0",
"babel-preset-react": "^6.11.1",
"jsx-loader": "^0.13.2",
"react": "^15.1.0",
"react-dom": "^15.1.0",
"react-hot-loader": "^1.3.0",
"webpack": "^1.13.1",
"webpack-dev-server": "^1.14.1"
}
}
</code></pre>
<p>Here is my Webpack configuration:</p>
<pre><code>var webpack = require('webpack');
var path = require('path');
var BUILD_DIR = path.resolve(__dirname, 'src/client/public');
var APP_DIR = path.resolve(__dirname, 'src/client/app');

]
},
plugins: [
new webpack.HotModuleReplacementPlugin()
]
};
module.exports = config;
</code></pre>
<p>After having executed <code>npm run start</code> and with this configuration, I see in my console that updates in a JSX file are detected but the browser isn't updated. Moreover, if I have a look at the <code>module.js</code> file, my updates aren't taken into account.</p>

Is it possible to do static code analysis for python using SonarQube?

<p>I need to check for errors in my python files before building the project. Is this possible using SonarQube? If Yes, what checks are performed for Python(syntax, indentation, import errors, etc)?</p>

Is there a way to programmatically add some default message to git commit?
|
<p>I am trying to auto generate my commit message title fetching directly from Phrabricator or Jira.</p>
<p>I have a bash script that does a http call and get the title. </p>
<p>I know you can have a commit template for each commit message.</p>
<p>eg.</p>
<p><code>~/.gitconfig</code></p>
<pre><code>[commit]
template = ~/.gitmessage
</code></pre>
<p><code>~/.gitmessage</code></p>
<pre><code>Some template for user
</code></pre>
<p>But is it possible to dynamically generate commit template using bash or python scripts?</p>

Capybara with Selenium: Can't click on hidden element
|
<p>I have a situation in my view where a clickable icon is only visible when it's containing div is hovered over (using Knockout JS, SCSS) . Something like this:</p>
<h1>HTML</h1>
<pre><code><div id="button_div">
<i id="icon" data-bind="click: dosomething"></i>
</div>
</code></pre>
<h1>SCSS</h1>
<pre><code>i {
display: none;
}
#button_div:hover {
i {
display: block;
}
}
</code></pre>
<p>Everything works fine on the page, but I can't seem to figure out how to click the element in Capybara. I've tried adding the :visible symbol to the method, but with no luck:</p>
<pre><code>find('#icon', visible: false).click
</code></pre>
<p>This gives me the a "Selenium::WebDriver::Error::ElementNotVisibleError" error.</p>
<p>Using:</p>
<pre><code>Capybara.ignore_hidden_elements = false
</code></pre>
<p>Gives me the exact same error</p>
<p>I've also tried using a Selenium Action such as:</p>
<pre><code>button_div_element = find('#button_div').native
button_element = find('#button', visible: false).native
page.driver.browser.action.move_to(button_div_element).click(button_element).perform
</code></pre>
<p>While this doesn't throw an error, it also doesn't click the button.</p>
<p>Does anyone have any idea what I might be doing wrong?</p>
