d8301 | train | There are no id attributes in your markup. All you are dealing with is innerText
$('td').click(function() {
var myItem = $(this).text();
alert('u clicked ' + myItem);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<table>
<tr>
<td>Computer</td>
</tr>
<tr>
<td>maths</td>
</tr>
<tr>
<td>physics</td>
</tr>
</table>
A: You have invalid markup. extra closing div is added after last tr closing markup. you need to remove it.
what you need to alert is text of element and not parent id. use .text() along with clicked td elements jquery context:
$('td').click(function(){
myItem=$(this).text();
alert('u clicked ' +myItem);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<table>
<tr><td>Computer</td></tr>
<tr><td>maths</td></tr>
<tr><td>physics</td></tr>
</table>
A: try this:
$('td').click(function () {
alert('u clicked ' + $(this).text());
});
A: As I have already commented, you are missing ID in tr. I have added few more tds for demo.
$('td').click(function() {
var myId = $(this).parent().attr("id");
var myItem = $(this).text();
alert('u clicked ' + myId);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>

d8302 | train | Your code is building an invalid URL:
http://api.website.com/apik=123456&q=some+search&l=San+Jose%2c+CA&sort=1&radius=100
Note the /apik=123456 portion.
var apiKey = "123456";
var Query = "some search";
var Location = "San Jose, CA";
var Sort = "1";
var SearchRadius = "100";
// Build a List of the querystring parameters (this could optionally also have a .ToLookup(qs => qs.key, qs => qs.value) call)
var querystringParams = new [] {
new { key = "k", value = apiKey },
new { key = "q", value = Query },
new { key = "l", value = Location },
new { key="sort", value = Sort },
new { key = "radius", value = SearchRadius }
};
// format each querystring parameter, and ensure its value is encoded
var encodedQueryStringParams = querystringParams.Select (p => string.Format("{0}={1}", p.key, HttpUtility.UrlEncode(p.value)));
// Construct a strongly-typed Uri, with the querystring parameters appended
var url = new UriBuilder("http://api.website.com/api");
url.Query = string.Join("&", encodedQueryStringParams);
This approach will build a valid, strongly-typed Uri instance with UrlEncoded querystring parameters. It can easily be rolled into a helper method if you need to use it in more than one location.
A: Use the UriBuilder class. It will ensure the resulting URI is correctly formatted. | unknown | |
d8303 | train | First of all, you'll need to identify in wich neighborhood you are clicking. Adding a rel (like in the options) might work:
...
<li class="evillage">
<a href="#" rel="asm0option0">East Village/LES</a>
</li>
...
Then, add this script:
$(".search-map a").click(function(event) {
event.preventDefault();
var hood = $(this).attr('rel');
var $option = $('option[rel=' + hood + ']');
$option.change();
return false;
});
Based on this asmselect example. You just need to get the correspondig option depending on the clicked link, and then call the change(); trigger on it.
EDITED:
The above code failed big time :P Here's the new version (With a working fiddle):
$(".search-map a").click(function() {
var $city = $(this).html();
var $rel = $(this).attr('rel');
var disabled = $('#asmSelect0 option[rel=' + $rel + ']:first').attr('disabled');
if (typeof disabled !== 'undefined' && disabled !== false) {
return false;
}
var $option = $('<option></option>').text($city).attr({'selected': true, 'rel': $rel});
$('#asmSelect0').append($option).change();
$('#asmSelect0 option[rel=' + $rel + ']:first').remove();
return false;
});
I had to do something I don't really like, but I couldn't find any other way of doing this without conflicting with the plugin. Anyway, it's not that bad. Basically I get the name of the neighborhood, the rel to identify the option, generate a new <option>, change(); it, and delete the old option tag. The plugin didn't like trying to change the tag itself without creating a new one... I had to add the if (...) thing because when adding a neighborhood (disabling it on the select), and clicking again on the same neighborhood, it enabled it on the select (And we don't want that, since it's already selected). With that condition, if we click on a link whose neighborhood is disabled, we'll do nothing and the option will remain the same.
Sorry if my explanation sucks, It took me a while to get the problem, I had to build everything up again, and I felt like having a lack of english xD Hope it works! | unknown | |
d8304 | train | The $scope.id attribute is probably not getting set.
Try setting the id in the scope in your showProduct function or whichever function initializes the $scope variables for the item.
$scope.showProduct = function(product){
$scope.id = product.id;
.............. | unknown | |
d8305 | train | I think the problem on that line;
OleDbDataAdapter dataadapter = new OleDbDataAdapter(sql, connectionString);
You add your parameters on your command but you still using sql string which expects parameter and their values in OleDbDataAdapter constructor.
Use your command instead of your sql query;
OleDbDataAdapter dataadapter = new OleDbDataAdapter(command, connectionString);
And use using statement to dispose your OleDbConnection, OleDbCommand and OleDbDataAdapter automaticaly.
As your second problem, from the documentaion of OleDbCommand.Parameters:
The OLE DB .NET Provider does not support named parameters for passing parameters to an SQL statement or a stored procedure called by an OleDbCommand when CommandType is set to Text.
Actually, it does support named parameters but names are negligible. Only matter is your parameter orders. Since you add @ID parameter your command first, this will be added to your first parameter in your command that you defined which is @grade. As you can see, this will generate a problem.
Change your parameters order as well;
command.Parameters.Add("@grade", OleDbType.VarChar).Value = grade;
command.Parameters.Add("@ID", OleDbType.VarChar).Value = ID; | unknown | |
d8306 | train | In an IAuthorizationPolicy.Evaluate() OperationContext.Current.InstanceContext is not always null.
Starting with Carlos Figueira’s WCF Extensibility test program which prints to the command line a message each time a WCF extension is called. I added a custom IAuthorizationPolicy. The output and program are below.
The output shows that
*
*IAuthorizationPolicy.Evaluate() Is called after the service instance is created
*OperationContext.Current.InstanceContext is not null in IAuthorizationPolicy.Evaluate()
The test program is self hosted using BasicHttpBinding. It’s very possible that in other hosting environments IAuthorizationPolicy.Evaluate() does not have access to the service instance, but it is at least theoretically possible.
Why would you do this?
From an architecture point of view an IAuthorizationPolicy should be dealing with claims. The application should be consuming the claims on the ClaimsPrinciple. To have an IAuthorizationPolicy tightly coupled to a particular service breaks the very intentional separation of concerns in the Window Identity architecture. In other words, I think this is a bad idea.
Test Program
This is a windows command line program all in one file.

d8307 | train | When you spin an EC2 instance up, the root volume is ephemeral - that is, when the instance is terminated, the root volume is destroyed** (taking any data you put there with it). It doesn't matter how you partition that ephemeral volume and where you tuck your data on it - when it is destroyed, everything contained in that volume is lost.
So if the data in the volume is entirely transient and fully recoverable/retrievable from somewhere else the next time you need it, there's no problem; terminate the instance, then spin a new one up and re-acquire the data you need to carry on working.
However, if the data is NOT transient, and needs to be persisted so that work can carry on after an instance crash (and by crash, I mean something that terminates the instance or otherwise renders it inoperable and unrecoverable) then your data MUST NOT be on the root volume, but should be on another EBS volume which is attached to the instance. If and when that instance terminates or breaks irretrievably, your data is safe on that other volume - it can then be re-attached to a new instance for work to continue.
** the exception is where your instance is EBS-backed and you swapped root volumes - in this case, the root volume is left behind after the instance terminates because it wasn't part of the 'package' created by the AMI when you started it.
A: The other volume would be needed in case your server gets broken and you cannot start it. In such case you would just remove initial server, create a second one and attach the additional storage to the new server. You cannot attach root volume of one server to another. | unknown | |

The 0 currently returned indicates that you don't have any groups, so there is nothing to show. | unknown | |

data <- data.frame(link = toString(tags$a(href = paste0("http://google.de"), "google")))

d8323 | train | When all 3 combo boxes are set it will enable the checkbox. Once the value for any combo box is updated it calls a common function which checks whether all combo boxes have a value assigned and accordingly set the checkbox.
Private Sub cmbClientContact_AfterUpdate()
Call SetCheckBox
End Sub
Private Sub cmbClientName_AfterUpdate()
Call SetCheckBox
End Sub
Private Sub cmbProjectManager_AfterUpdate()
Call SetCheckBox
End Sub
Private Sub SetCheckBox()
If Nz(Me.cmbClientContact, "") <> "" And Nz(Me.cmbClientName, "") <> "" And Nz(Me.cmbProjectManager, "") <> "" Then
Me.Check25 = True
Me.Text27.Enabled = True
Else
Me.Check25 = False
End If
End Sub
Enable/disable textbox basis value of the checkbox
Private Sub Check25_AfterUpdate()
If Nz(Me.Check25, False) Then
Me.Text27.Enabled = True
Else
Me.Text27.Enabled = False
End If
End Sub
A: I would reccomend using the AfterUpdate event of all 3 combo boxes. Since the code is going to be the same (you're checking if all 3 combo boxes have a value), you can create one function to handle the check, and set that function to the AfterUpdate event of all 3 combo boxes when the form loads.
The function to update the controls (both the text box and check box) would be something like this:
Private Function UpdateControls()
Me.Text1.Enabled = Not (IsNull(Me.Combo1) Or IsNull(Me.Combo2) Or IsNull(Me.Combo3))
Me.Check1.Value = Not (IsNull(Me.Combo1) Or IsNull(Me.Combo2) Or IsNull(Me.Combo3))
End Function
You can call this function when the form initially loads, so the checkbox will be unchecked and the textbox will be disabled:
Private Sub Form_Load()
' update controls initially when the form loads
UpdateControls
End Sub
To make sure the same update happens whenever one of the combo box's values are updated, you can set each combobox's AfterUpdate event to the same function, like this:
Private Sub Form_Load()
' set each combo box's AfterUpdate event to run the check
Me.Combo1.AfterUpdate = "=UpdateControls()"
Me.Combo2.AfterUpdate = "=UpdateControls()"
Me.Combo3.AfterUpdate = "=UpdateControls()"
End Sub
So your final code might be something like this:
Private Sub Form_Load()
' set each combo box's AfterUpdate event to run the check
Me.Combo1.AfterUpdate = "=UpdateControls()"
Me.Combo2.AfterUpdate = "=UpdateControls()"
Me.Combo3.AfterUpdate = "=UpdateControls()"
' update controls initially when the form loads
UpdateControls
End Sub
Private Function UpdateControls()
Me.Text1.Enabled = Not (IsNull(Me.Combo1) Or IsNull(Me.Combo2) Or IsNull(Me.Combo3))
Me.Check1.Value = Not (IsNull(Me.Combo1) Or IsNull(Me.Combo2) Or IsNull(Me.Combo3))
End Function
A: Without knowing more specifics about the name schemas of your objects, this is my semi-vague answer:
One option (of many) is to use an On Click event procedure with the following:
If Not IsNull(Me.Combo1) _
And Not IsNull(Me.Combo2) _
And Not IsNull(Me.Combo3) Then
Me.Check1 = True
Me.Text1.Enabled = True
Else
Me.Check1 = False
Me.Text1.Enabled = False
End If
This assumes that the checkbox is named Check1 and the textbox is named Text1 and the comboboxes are Combo1, Combo2, and Combo3
It is a little confusing whether you meant Enabled or Visible, but if you meant Visible, just change the lines that say .Enabled to .Visible | unknown | |

d8327 | train | The text function will set text, not HTML.
You need replace the newlines in the generated HTML:
$("#some-div").text($("#some-textarea").val())
.html(function(index, old) { return old.replace(/\n/g, '<br />') });
Note that you cannot set the HTML directly from the textarea, because that won't escape HTML tags.
Also, unlike PHP, Javascript uses regex literals, so you cannot put a regex in a string.
A: Rather than treating HTML as a string, I would suggest creating DOM nodes. Normalize the textarea value (IE uses \r\n rather than \n), split the textarea value on line breaks and create text nodes separated by <br> elements:
var div = $("#some-div")[0];
var lines = $("#some-textarea").val().replace(/\r\n/g, "\n").split("\n");

d8331 | train | It can be done the way you propose, but the idea for callbacks sent as an argument to another function is to make them non-static callable objects (fitted for any purpose) instead of one implementation per use-case. Also, you don't always have access to invoke the "callback" function (called the way you intend to) due to scope restrictions. | unknown | |
d8332 | train | Yes, the interpreter can always release the GIL; it will give it to some other thread after it has interpreted enough instructions, or automatically if it does some I/O. Note that since recent Python 3.x, the criteria is no longer based on the number of executed instructions, but on whether enough time has elapsed.
To get a different effect, you'd need a way to acquire the GIL in "atomic" mode, by asking the GIL not to be released until you release it explicitly. This is impossible so far (but see https://bitbucket.org/arigo/cpython-withatomic for an experimental version).
A: As Armin said, the GIL can be released inside PyEval_EvalCode. When it returns, it is of course acquired again.
The best way is just to make sure that your code can handle that. For example, incref any objects where you have C pointers to before the GIL might get released. Also, be careful if there might be cases where the Python code again calls the very same function. If you have another mutex there, you can easily end up in a dead-lock. Use recursive-safe mutexes and while waiting on them, you should release the GIL so that the original thread can releases such mutexes. | unknown | |
d8333 | train | I believe the license you purchased to use Jira gives you access to the api without further cost.
First steps?
The second link you gave in your post relating to the api (docs.atlassian.com/jira/REST/cloud/) gives you everything you need to know if you understand its content.
Googling nodejs jira api gave a number of package results that would make interacting with the api very easy. At the time node-jira was top of the list and looked like it suited your needs. There are other packages too so worth looking around.
General pointers:
*
*Start on a list of nodejs packages you will need to build your app from what you know and package searches. Initialize your node project and start adding those packages to package.json.
*Identify the Jira authentication method you are going to use.
*
*The api supports basic over https or oauth and cookie once authenticated.
*Find examples of how the package you are using handles authentication. It should be easy in the package readme or with google.
*Identify the API calls that will give you the data you need.
*
*The options are easy to find in node-jira readme if using it or use the api docs.
*The jira api documentation will give you the expected json response schema that you will need to access the json you get back.
*An example would be the Projects api definition. It gives you an example response and the full response schema.
*The api options are described as 'expandable' which means you only get what you ask for, if you want more you have to ask for it. (see expand option for each api call)
*Consider what you need to process the data you get back and display it in whatever format you require.
*
*Again more package options, json processing, templating.
*If it is a web page you might need something like express.
*Use that information to start coding (not in any specific order).
*
*Code for getting requests (say a web page).
*Code for authentication and api calls.
*Code for templating each data view of api response data.
*Code the overall app structure.
*Give yourself some debug messages that can be turned on and off so you can see process sequence which can help a lot in troubleshooting.
*Write test scripts! Change code.... run the test/s, got a new feature... write a test then code to the test. Retest before release.
There are lots of package options, information, and examples. Use Google lots, search npmjs.com for packages, use the api docs. | unknown | |

1. Use one git repository

As below example, if you project (the files you want to manage in git repo) is under Dir2 (not contains it’s parent Dir1), then you should remove the other two repos for Dir1 and Dir3 by removing the folders Dir1/.git and Dir1/Dir2/Dir3/.git.
Dir1
|___.git
|___ …
|___Dir2
|___.git
|___ …
|___Dir3
|___.git

*If you mean 3 gits are 3 git branches for the same git repo, before switching branches, you should make sure the work directory is clean (save and commit changes before switching branches).
2. Mark sure user.name and user.email has already been set
You can use the command git config -l to check if the output contains:
user.name=<username>
user.email=<email address>

d8340 | train | The link to the airfoil database contains the coordinates of a NACA0012 in the Lednicer format, while the code in AeroPython Lesson was written for an airfoil in Selig's format.
(The Notebook compute the flow around an airfoil using a source-panel method.)
Selig's format starts from the trailing edge of the airfoil, goes over the upper surface, then over the lower surface, to go back to the trailing edge.
Lednicer's format lists points on the upper surface (from leading edge to trailing edge), then points on the lower surface (from leading edge to trailing edge).
You can load the Selig's format (skipping the header "NACA 0012 AIRFOILS" with skiprows=1 in numpy.loadtxt) as follow:
import urllib
# Retrieve and save geometry to file.
selig_url = 'http://airfoiltools.com/airfoil/seligdatfile?airfoil=n0012-il'
selig_path = 'naca0012-selig.dat'
urllib.request.urlretrieve(selig_url, selig_path)
# Load coordinates from file.
with open(selig_path, 'r') as infile:
x1, y1 = numpy.loadtxt(infile, unpack=True, skiprows=1)
The NACA0012 airfoil here contains 131 points and you will see that the trailing edge has a finite thickness:
print('Number of points:', x1.size) # -> 131
print(f'First point: ({x1[0]}, {y1[0]})') # -> (1.0, 0.00126)
print(f'Last point: ({x1[-1]}, {y1[-1]})') # -> (1.0, -0.00126)
If you do the same with the Lednicer's format (with skiprows=2 for the header), you will load 132 points (leading-edge point is duplicated) with points on the upper surface being flipped (from leading edge to trailing edge).
(That's why you observe this line in the middle with pyplot.plot; the line connects the trailing edge from the upper surface to the leading edge from the lower surface.)
One way to re-orient the points to follow Selig's format is to skip the leading edge on the upper surface (i.e., skip the duplicated point) and flip the points on the upper surface.
Here is a possible solution:

d8341 | train | You should put all your formcontrols in a formGroup
myFormGroup: FormGroup = this.fb.group({
name: new FormControl('name'),
description: new FormControl('description'),
price: new FormControl('price'),
inventory: new FormControl('inventory'),
category: new FormControl('category'),
image_url: new FormControl('image_url'),
});
In order to do so, you need to be able to make a formGroup, thus have the FormBuilder dependency injected.
constructor(..., private fb: FormBuilder) {}
The above code of grouping formcontrols can be done easier like this:
myFormGroup: FormGroup = this.fb.group({
name: [''],
description: [''],
price: [''],
inventory: ['']),
category: [''],
image_url: [''],
});
You will need to add the formGroup to your HTML template aswell
<form [formGroup]="myFormGroup" (ngSubmit)="updateItem()" autocomplete="off" novalidate>
...
</form>
Lastly, you can print the values in your submit function by adding likes this
updateItem() {
if (this.myFormGroup.valid) //Not necessary since you don't use validators
console.log(this.myFormGroup.value)
}
All this information and more can be found on the Reactive Forms Documentation of Angular | unknown | |

d8344 | train | Instead of:
Element.extend(elt);
Try:
elt = Element.extend(elt);
or
elt = $(elt);
As for how to do the traversing before you've inserted the node, here's some random examples that illustrate a few features of Prototype:
var elt = new Element('div', {
className: 'someClass'
});
elt.insert(new Element('ul'));
var listitems = ['one', 'two', 'three'];
listitems.each(function(item){
var elm = new Element('li');
elm.innerHTML = item;
elt.down('ul').insert(elm);
});
elt.getElementsBySelector('li'); //=> returns all LIs
elt.down('li'); //=> returns first li
elt.down('ul').down('li'); //=> also returns first li
elt.down('ul').down('li', 2); //=> should return the third if I'm not mistaken
// all before inserting it into the document!
Check the brand new API documentation.
Answering Ollie: my code above can be tested here, as you can see it works under IE 6.
A: I don't think it is possible to select nodes that are not in the document, because the selector depends on the document node.
And you should build new elements this way :
var elt = new Element("div"); | unknown | |
d8345 | train | It is because, refModels.once('value').then is async meaning that JS starts its execution and continues to next line which is console.log and by the time console.log is executed $scope.theModel hasn't been populated with data yet.
I suggest you read this
Asynchronous vs synchronous execution, what does it really mean?
You can still access your $scope.theModel in other functions, but you have to make sure it is loaded first.
Edit
refModels.once('value').then(function (snapshot) {
snapshot.forEach(function (snapshot) {
var usersValue = snapshot.val();
console.log("users values", usersValue.carModel);
$scope.theModel = usersValue.carModel;
console.log("The model" + $scope.theModel); //output "e90"
});
$scope.processData();
});
$scope.processData = function() {
// here $scope.theModel exists
// do some code execution here with $scope.theModel
// call your other firebase.database.ref("models") here
};
A: Ok so finally got it working, with Bunyamin Coskuner solution, the only thing I had to fix is to return $scope.processData;
var UserID = firebase.auth().currentUser.uid;
var refModels = firebase.database().ref("/users/" + UserID);
refModels.once('value').then(function(snapshot) {
console.log(snapshot)
snapshot.forEach(function(childSnapshot) {
console.log(childSnapshot)
var usersValue = childSnapshot.val();
// var theModel = usersValue.carModel;
console.log("The model", usersValue.carModel); //output "e90"
$scope.theModel = usersValue.carModel;
***return $scope.processData;*** // we have to return it here
});
$scope.processData();
});
$scope.processData = function (){
console.log("Process Model" + $scope.theModel); // now returns the value e90
$scope.carDetails = [];
firebase.database().ref("models").once('value').then(function(snapshot) {
snapshot.forEach(function(userSnapshot) {
var models = userSnapshot.val();
console.log(models);
if (models.brand == $scope.theModel){
$scope.carDetails.push(models);
}
});
});
}
It seems to be a very common mistake made by new javascript developers, the Async behaviour, so its good to read about it.
In this solution we called a function from inside of then function. That way, we'll have for sure the data, that can be used in other function
A: Your $scope.theModel gets set inside the "then" block as expected, but being async, this happens after the second console.log (outside the function) is invoked.
If you use angular components, you can init theModel inside $onInit method:
angular.module('app', []).component('myComponent', {
bindings: {
title: '@'
},
controller: function() {
this.$onInit = function() {
// Init the variable here
$scope.theModel = null;
});
//Following code should not be in the controller, but in a service (here just as sample)
var refModels = firebase.database().ref("/users/" + $scope.UserID);
refModels.once('value').then(function (snapshot) {
snapshot.forEach(function (snapshot) {
var usersValue = snapshot.val();
console.log("users values", usersValue.carModel);
// From this moment your variable is set and available outside
$scope.theModel = usersValue.carModel;
});
},
templateUrl: 'template.html'
});
A: You can watch the value changing. Async behaviour is explained in another answer.
$scope.$watch('theModel', function(newVal){
console.log(newVal);
});
Also I would use $evalAsync() on $scope.theModel = usersValue.carModel;
$scope.$evalAsync(function(){
$scope.theModel = usersValue.carModel;
}); | unknown | |
d8346 | train | It seems like you are not setting Headers properly in your HTTP Request body, try the following code,

let parametros = new HttpParams().set("command", "register");
user.verif = key;
return this.http.post(this.url, user, {Headers: parametros}).toPromise();

d8347 | train | The issue was that I needed CascadeType.MERGE on the Aircraft entity:
@ManyToOne(cascade={CascadeType.PERSIST, CascadeType.MERGE}, fetch = FetchType.EAGER)
private Client owner;
@ManyToOne(cascade={CascadeType.PERSIST, CascadeType.MERGE}, fetch = FetchType.EAGER)
private Client operator;
Essentially, when JSON is input to a create operation, it appears to be indistinguishable from a MERGE operation (where a new entity is created and put under management, unlike PERSIST) and so a MERGE operation is passed into Client, not PERSIST (as I would have expected). This is why Person and Contact were not being persisted. I still don't understand why JSON input is being treated like a merge though - it doesn't make sense. | unknown | |
d8348 | train | As far as cropping images are concerned you can use the WriteableBitmapEx library on codeplex.
Now you just need to draw a rectangle on a canvas containing the image to describe the crop region. | unknown | |
d8349 | train | Simply use the contour function with a 2nd argument of desired values (it is a vector of 2 elements instead of a scalar, to distinguish the function call from another mode):

d8350 | train | To resolve the issue with COALESCE/IFNULL still returning NULL for the WITH ROLLUP placeholders, you need to GROUP BY the table column names, rather than the aliased column expressions.
The issue is caused by the GROUP BY clause being specified on the aliased column expressions, because the aliases are assigned after the column expression is processed.
Resulting in the WITH ROLLUP NULL placeholders not being in the recordset to be evaluated by COALESCE.
Meaning the aliases DEALER, SERVICE_ADVISOR in the GROUP BY do not exist until after IFNULL/COALESCE have already been executed.
See MySQL Handling of GROUP BY for more details.
Example DB-Fiddle
CREATE TABLE foo (
`amount` INTEGER,
`created` INTEGER
);
INSERT INTO foo
(`amount`, `created`)
VALUES
('1', '2019'),
('2', '2019');
Query #1 (Reproduce Issue)

Considerations
*
*
With MySQL 5.7+ and ONLY_FULL_GROUP_BY enabled, selected
non-aggregate columns that are not specified in the GROUP BY clause
will fail. Meaning the following query will not work as expected: DB-Fiddle
SELECT COALESCE(YEAR(foo), 'foo') /* ... */ GROUP BY YEAR(foo) WITH ROLLUP
-> ER_WRONG_FIELD_WITH_GROUP: Expression #2 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'test.foo_bar.foo' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by
*
COALESCE,
IFNULL,
IF(... IS NULL)
and CASE WHEN ... IS NULL
will all function
similarly. Where IFNULL is the proprietary to MySQL and is a less
functional replacement of COALESCE. As COALESCE can accept more
than two parameters to check against NULL, returning the first non-NULL value.
mysql> SELECT COALESCE(NULL, NULL, 1, NULL);
-> 1
mysql> SELECT IFNULL(NULL, 1);
-> 1
mysql> SELECT IF(NULL IS NULL, 1, '');
-> 1
mysql> SELECT CASE WHEN NULL IS NULL THEN 1 END;
-> 1
*
nullable columns in the GROUP BY as either aliases or column names, will result in the NULL values being
displayed as the WITH ROLLUP placeholder. This applies to using WITH ROLLUP in general. For example if
users.name can return NULL. DB-Fiddle
| DEALER | SERVICE_ADVISOR | COMPLETED |
| ------ | --------------- | --------- |
| Foo | TOTAL | 1 |
| Foo | Jane Doe | 1 |
| Foo | John Doe | 1 |
| Foo | TOTAL | 3 |
| GROUP | TOTAL | 3 |
Prevent NULL column values from being displayed
To ensure that nullable columns are not accidentally included, you would need to specify in the criteria to exclude them.
Example DB-Fiddle
SELECT
COALESCE(usergroups.name, 'GROUP') AS DEALER,
COALESCE(users.name, 'TOTAL') AS SERVICE_ADVISOR,
COUNT(DISTINCT vcrs.uid) AS COMPLETED
FROM vcrs
LEFT JOIN users
ON users.id = vcrs.uid
LEFT JOIN usergroups
ON usergroups.id = users.group_id
WHERE vcrs.vcrSubStatus = 4
AND users.name IS NOT NULL
GROUP BY usergroups.name, users.name
WITH ROLLUP;
Result
| DEALER | SERVICE_ADVISOR | COMPLETED |
| ------ | --------------- | --------- |
| Foo | Jane Doe | 1 |
| Foo | John Doe | 1 |
| Foo | TOTAL | 2 |
| GROUP | TOTAL | 2 |
Since LEFT JOIN is used on the vcrs table, IS NOT NULL must be
applied to the WHERE clause, instead of the ON clause. As LEFT JOIN returns NULL for non-matching criteria. To circumvent the
issue, use an INNER JOIN to limit the resultset to only those with
matching ON criteria.
/* ... */
INNER JOIN users
ON users.id = vcrs.uid
AND users.name IS NOT NULL
/* ... */
WHERE vcrs.vcrSubStatus = 4
GROUP BY usergroups.name, users.name
WITH ROLLUP;
Include NULL columns values
To explicitly include nullable column values, without duplicating the WITH ROLLUP placeholder name, you would need to utilize a derived table subquery to substitute the NULL value as a textual value.
Example DB-Fiddle
SELECT
COALESCE(v.usergroup_name, 'GROUP') AS DEALER,
COALESCE(v.user_name, 'TOTAL') AS SERVICE_ADVISOR,
COUNT(DISTINCT v.uid) AS COMPLETED
FROM (
SELECT
usergroups.name AS usergroup_name,
COALESCE(users.name, 'NULL') AS user_name,
vcrs.uid
FROM vcrs
LEFT JOIN users
ON users.id = vcrs.uid
LEFT JOIN usergroups
ON usergroups.id = users.group_id
WHERE vcrs.vcrSubStatus = 4
) AS v
GROUP BY v.usergroup_name, v.user_name
WITH ROLLUP;
Result
| DEALER | SERVICE_ADVISOR | COMPLETED |
| ------ | --------------- | --------- |
| Foo | Jane Doe | 1 |
| Foo | John Doe | 1 |
| Foo | NULL | 1 |
| Foo | TOTAL | 3 |
| GROUP | TOTAL | 3 |
You can also optionally replace the 'NULL' textual placeholder as desired and even display it as NULL.
SELECT
COALESCE(v.usergroup_name, 'GROUP') AS DEALER,
CASE v.user_name WHEN 'NULL' THEN NULL ELSE COALESCE(v.user_name, 'TOTAL') END AS SERVICE_ADVISOR,
COUNT(DISTINCT v.uid) AS COMPLETED
FROM (
/* ... */
) AS v
GROUP BY v.usergroup_name, v.user_name
WITH ROLLUP;
A: I'm only 2 years too late, but since I came across the same issue as @the_gimlet I thought I'd post the answer.
So don't know if this is a mySQL versioning or something, but using mysql 5.6 I get the same problem... ifnull will not replace the rollup 'nulls'.
Simply get around this by making your rollup a subquery, and doing the ifnulls in the main select... annoying to repeat the select, but it works!
e.g. for example above
SELECT
IFNULL(`DEALER`, 'GROUP') AS DEALER,
IFNULL(`SERVICE_ADVISOR`, 'TOTAL') AS SERVICE_ADVISOR,
`COMPLETED`,
/* .......... */
FROM (SELECT
usergroups.name AS DEALER,
users.name AS SERVICE_ADVISOR,
COUNT(DISTINCT vcrs.uid) AS COMPLETED,
/* .......... */
AND vcrs.vcrSubStatus = 4
GROUP BY DEALER, SERVICE_ADVISOR with ROLLUP);
A: Do you want something like this?
SELECT COALESCE(usergroups.name, 'GROUP') AS DEALER,
COALESCE(users.name, IF(usergroups.name IS NULL, 'TOTAL', 'SUBTOTAL')) AS SERVICE_ADVISOR,
COUNT(DISTINCT vcrs.uid) AS COMPLETED,
..........
..........
AND vcrs.vcrSubStatus = 4
GROUP BY DEALER, SERVICE_ADVISOR with ROLLUP;

A: What you're looking for is a case statement.
What you're saying is that under a certain condition replace the found value with the one specified. You can use multiple when/then statements depending on how customised you'd like the replacements to be.

case when(users.name is null) then 'TOTAL' else users.name end AS SERVICE_ADVISOR,

d8358 | train | Those are just padding 0x00 characters added at the end, because the string's length for that cryptographic algorithms has to be a multiple of 16 (with 128 bit).
Indeed, if you add at the end of your code:
var_dump(bin2hex(Cipher::decrypt($emailAddress, $iv)));
You can see that the last 6 characters are all 0's (which means there are 3 0x00 bytes at the end).
To remove them, just run:
$decrypted = rtrim($decrypted, "\0"); | unknown | |
d8359 | train | It's all a matter of tradeoffs -- in this case, you want just enough complexity to handle a reasonable number of cases.
If there are only two options, I think that if statement looks just fine. A 'case' statement (aka a switch statement) can be DRYer, and you may want to explicitly say "movie.txt", e.g.
@word = (case file_name
when "word.txt"
Word
when "movie.txt"
Movie
else
raise "Unknown file name #{file_name}"
end).new(file_name)
or extract a class_for_file_name method if you don't like putting a case statement in parens, even though it's pretty fun.
If your set of polymorphic classes gets bigger, you might get more mileage out of a lookup table:
class_for_file_name = {
"word.txt" => Word,
"movie.txt" => Movie,
"sandwich.txt" => Sandwich,
}
@word = class_for_file_name[file_name].new(file_name)
And of course, maybe you're oversimplifying and you really want to switch on the file extension, not the file name, which you could get with File.extname(file_name).
You could also get even fancier and ask each concrete class whether it handles this file name; this feels more OO -- it puts the knowledge about foos inside the Foo class -- but is arguably more complicated:
class Word
def self.good_for? file_name
file_name == "word.txt"
end
end
class Movie
def self.good_for? file_name
file_name == "movie.txt"
end
end

d8360 | train | But if I receive FulfillmentResult.PurchaseReverted, then what
happened? How did the user just revert the purchase? Am I meant to
withdraw their Coins/Gems/Potatoes?
The value PurchaseReverted means the transaction is canceled on the backend and users get their money back. So you should disable the user's access to the cosumable content (withdraw the Coins/Gems/Potatoes) as necessary.
What are scenarios behind the other error messages?
NothingToFulfill : The transaction id has been fulfilled or is otherwise complete
PurchasePending: The purchase is not complete. At this point it is still possible for the transaction to be reversed due to provider failures and/or risk checks. It means the purchase has not yet cleared and could still be revoked.
ServerError: There was an issue receiving fulfillment status. It might be the problem from the Store.
Succeed: The fulfillment is complete and your Coins/Gems/Potatoes can be offered again.

d8361 | train | How should I assign new documents to these topics?
Once you have a trained model you can query the model for your document with:
doc_bow = model.id2word.doc2bow(doc.split()) # convert to bag of words format first
doc_topics, word_topics, phi_values = model.get_document_topics(bow, per_word_topics=True)
re.
This code is going to provide you with per-doc and per-word information about the level of belonging to a particular topic. This means the per-word calculations are done for you automatically.
How do I assign the main keywords that denote the topic?
it is difficult to understand what you mean. The keywords denoting a topic along with their weights are the actual LDA model that you got from the training using a corpus.
I suppose you may be interested in reviewing the following notebook [*] for more information how to query model for specific information regarding a document (per-word topic information, etc.).

d8362 | train | try
2748.ToString("X")
A: If you want exactly 3 characters and are sure the number is in range, use:
i.ToString("X3")
If you aren't sure if the number is in range, this will give you more than 3 digits. You could do something like:
(i % 0x1000).ToString("X3")
Use a lower case "x3" if you want lower-case letters.
A: Note: This assumes that you're using a custom, 12-bit representation. If you're just using an int/uint, then Muxa's solution is the best.
Every four bits corresponds to a hexadecimal digit.
Therefore, just match the first four digits to a letter, then >> 4 the input, and repeat.
A: The easy C solution may be adaptable:
char hexCharacters[17] = "0123456789ABCDEF";
void toHex(char * outputString, long input)
{
outputString[0] = hexCharacters[(input >> 8) & 0x0F];
outputString[1] = hexCharacters[(input >> 4) & 0x0F];
outputString[2] = hexCharacters[input & 0x0F];
}
You could also do it in a loop, but this is pretty straightforward, and loop has pretty high overhead for only three conversions.
I expect C# has a library function of some sort for this sort of thing, though. You could even use sprintf in C, and I'm sure C# has an analog to this functionality.

d8363 | train | We can use the column names of df to check whether each file is %in% each column inside an sapply. This will give us a square matrix which tells us whether each file contains every other file.
This way, it is straightforward to use array indexing to get the files which contain other files:
tab <- `rownames<-`(sapply(df, function(x) names(df) %in% x), names(df))
ind <- which(tab, arr.ind = TRUE)
AinB <- data.frame(item = names(df)[ind[,2]], contains = names(df)[ind[,1]])
AinB
#> item contains
#> 1 cy1.CSV cy1.CSV
#> 2 cy1.CSV cy24.CSV
#> 3 cy1.CSV cy6.CSV
#> 4 cy2.CSV cy2.CSV
#> 5 cy24.CSV cy1.CSV
#> 6 cy24.CSV cy24.CSV
#> 7 cy24.CSV cy6.CSV
#> 8 cy3.CSV cy3.CSV
#> 9 cy6.CSV cy1.CSV

#> 18 ds.CSV ds_1.CSV
#> 19 ds_1.CSV ds.CSV
#> 20 ds_1.CSV ds_1.CSV
To find instances in which A is in B but not vice versa, we do the same thing except we are looking for the indices where tab is different from its transpose:
ind2 <- which(tab & !t(tab), arr.ind = TRUE)
AinBnotBinA <- data.frame(item = names(df)[ind2[,2]],
contains = names(df)[ind2[,1]])

d8364 | train | You can't print binary with printf. You could print hex which is quite easy to relate to its binary representation (with %02X e.g.).
If you insist on printing binary, you would have to write a function for it. The function would be quite simple. If you have n bits, you could loop n times, do a shift by 1 and based on the carry either print 0 or 1. A bit more efficiently, you could store the result in a buffer and then print it all at once with %s.
Depending on how much memory you have (since it's x86 it's unlikely (impossible?) that it's embedded, so you probably do have a lot of memory), you can also store a table with the '0'-'1' representations of the bytes. That table would take 256*(8+1) bytes (one for '\0' if you use %s) for 8-bit values and you would need to hard-code it (perhaps generate with another program).
So far, I told you the two extremes: calculate all vs store all. The first can be slow and the second take a lot of space (and also tedious to generate).
To get the best of both worlds, you can have a table that stores the '0'-'1' representations of nibbles (4 bits). That table would be a mere 16*(8+1) bytes. Printing a byte would then be printing first its most significant and then its least significant nibble.
In C, this would look like this:
const char *bit_rep[16][5] = {
[ 0] = "0000", [ 1] = "0001", [ 2] = "0010", [ 3] = "0011",
[ 4] = "0100", [ 5] = "0101", [ 6] = "0110", [ 7] = "0111",
[ 8] = "1000", [ 9] = "1001", [10] = "1010", [11] = "1011",
[12] = "1100", [13] = "1101", [14] = "1110", [15] = "1111",
};
void print_byte(uint8_t byte)
{
printf("%s%s", bit_rep[byte >> 4], bit_rep[byte & 0x0F]);
} | unknown | |
d8365 | train | You could always just first slice the array into 2 parts (assuming it's not bigger then 2 times those rows). After that encode it, and add them together again. In case that isn't a solution, you need to increase your memory limit.
Here is an example, test it here. On @GeertvanDijk suggestion, I made this a flexible function, in order to increase functionality!
<?php
$bigarray = array(1,2,3,4,5,6,7,8,9);
function json_encode_big($bigarray,$split_over = 6670){
$parts = ceil((count($bigarray) / $split_over));
$start = 0;
$end = $split_over;
$jsoneconded = [];
for($part = 0; $part < $parts; $part++){
$half1 = array_slice($bigarray,$start,$end);
$name = "json".$part;
$$name = ltrim(rtrim(json_encode($half1),"]"),"[");
$jsoneconded[] = $$name;
$start += $split_over;
}
return "[".implode($jsoneconded,",")."]";
}
print_r(json_encode_big($bigarray));
?>
I have now test this with more rows then 6,670. You can test it online here as well.
Now, I have to mention that I tested the normal json_encode() with a million rows, no problem. Yet, I still hope this solves your problem...
In case that you run out of memory, you can set the memory_limit to a higher value. I would advice against this, instead I would retrieve the data in parts, and procces those in parts. As I don't know how you retrieve this data, I can't give an example how to regulate that. Here is how you change the memory in case you need to (sometimes it is the only option, and still "good").
ini_set("memory_limit","256M");
In this case, it is the dubbel from the default, you can see that it is 128M in this documentation
A: Possibly depends on your PHP version and the memory allowed for use by PHP (and possibly the actual size of all the data in the array, too).
What you could do if all else fails, is this:
Write a function that checks the size of a given array, then split off a smaller part that will encode, then keep doing this until all parts are encoded, then join them again. If this is the route you end up taking, post a comment on this answer, and perhaps I can help you out with it. (This is based on the answer by Nytrix)
EDIT, example below:
function encodeArray($array, $threshold = 6670) {
$json = array();
while (count($array) > 0) {
$partial_array = array_slice($array, 0, $threshold);
$json[] = ltrim(rtrim(json_encode($partial_array), "]"), "[");
$array = array_slice($array, $threshold);
}
$json = '[' . implode(',', $json) . ']';
return $json;

d8370 | train | Javascript has a Array.find(function(element(){}) function that you can use to look up values in an array, and inside the function(element){} you define the matching criteria .
Here the parameter to the Array.find() function is passed as the function(element), in this case, findProducts(), and additional parameters to the find function is given as another argument following the comma (in this case p.id).
You can pass any number of arguments while calling the function, and they'll all be accessible using an array indexing approach. For example, you can do
somefunction(someOtherFunction, a, b, c)...
...
Later you can access these values:
a will be this[0]
b will be this[1]
c will be this[2]
A: this.products.find(this.findProducts, [p.id])
findProducts(p) {
return p.id === this[0];
}
above function is the expansion of
this.products.find(product=>product.id == p.id)
It will iterate through all array element and returns matching product with given p.id
A: The Mozilla documentation gives some insight into what the second argument to find is, namely thisArg:
Object to use as this when executing callback.
So in your example, the callback is findProducts and thisArg is an array containing one element (which is a slightly weird approach to be honest).
Without thisArg, this inside findProducts would not be that array.
Below is a working demo. Note that without thisArg, this in findProducts is the window object. With thisArg, it is the second array parameter:
var arr = [
{id: 1, name: 'a'},
{id: 2, name: 'b'},
{id: 3, name: 'c'},
{id: 4, name: 'd'}
];
function findProducts(p) {
console.log('in findProducts', p);
console.log(this);
return p.id === this[0];
}
var f = arr.find(p => findProducts(p));
console.log('without thisArg', f);
f = arr.find(findProducts, [1]);
console.log('with thisArg', f);
A: You can do is in your findProducts fn
findProducts(p) {
let result = this.products.findIndex(item=>item.id === p.id);
return result // here the result will contain -1 if value is not present else it will contain some value

If you can watch it. If not I will try to explain.
The problem I believe is that IRegionManager from the container is a singleton and whenever you use it it is the same instance, so when you are trying to inject a region in an already injected region it will not work and you need to have a separate RegionManager for nested views.
This should fix it.

In your App.xaml
protected override void RegisterTypes(IContainerRegistry containerRegistry)
{
containerRegistry.RegisterSingleton<IRegionNavigationContentLoader,ScopedRegionNavigationContentLoader>();
}
protected override void ConfigureDefaultRegionBehaviors(IRegionBehaviorFactory regionBehaviors)
{
base.ConfigureDefaultRegionBehaviors(regionBehaviors);
regionBehaviors.AddIfMissing(RegionManagerAwareBehaviour.BehaviorKey, typeof(RegionManagerAwareBehaviour));
}
Coming to the finish.
Now in your ViewModelB implement IRegionManagerAware and have it as a normal property
public IRegionManager RegionManager { get; set; }
Then at your ViewB implement ICreateRegionManagerScope and have it as a get property
public bool CreateRegionManagerScope => true;
Now it should work.

d8373 | train | I believe that contains functionality can only be used in tables configured to use/support Full Text Search -- an elderly feature of SQL Server that I have little experience with. If you are not using Full Text Search, I'm pretty sure contains will not work.
A: Before CONTAINS will work against a column you need setup full text index. This is actually a different engine which runs as a separate service in SQL Server, so make sure it is installed an running.
Once you're sure the component is installed (it may already be installed) You need to do the following:
*
*Create a Full-Text Catalogue
*Create a Full-Text Index (you can have multiple of these in the same catalogue) against the tables/columns you want to be able to use full-text keywords
*Run a Population which will crawl the index created & populate the catalogue (these are seperate files which SQL Server needs to maintain in addition to mdf/ldf )
There's an ok tutorial on how to do this by using SSMS in SQL Server 2008 by Pinal Dave on CodeProject. SQL Server 2014 should be very similar.
You can also perform these steps with TSQL:
*
*CREATE FULLTEXT CATALOG

d8377 | train | Going through the logic of the given code we can see that the animation-duration is always set to the same amount (7s) on every click - it never changes after the first click:
var increasePlus = document.getElementById("plus");
increasePlus.addEventListener('click', () => {
var sec= 5 + "s";
if(sec=="5s"){//this is always true as sec has just been set to 5s
sec = 6 + "s";//so sec is set to 6s
increasePlus.style.animationDuration = sec;
}
if(sec=="6s"){//this is always true as sec has (just) been set to 6s
sec = 7 + "s";//so sec is now set to 7s
increasePlus.style.animationDuration = sec;//and so the animation-duration is ALWAYS set to 7s on a click
}
});
It is difficult to click on a moving object which is what the given code seems to require (the clickable element id plus is also the one given the animation duration in that code) so in this snippet the plus element gets clicked and that updates the animation duration of a separate object which is the one that moves.
const increasePlus = document.getElementById("plus");
const theObject = document.getElementById('object');
increasePlus.addEventListener('click', () => {
//get the current animation-duration
//remember this has an s at the end so we need to get rid of that so we can add to it
let sec= window.getComputedStyle(theObject, null)["animationDuration"].replace('s','');
//add 1 to it
sec++;
//and set the animation-duration
theObject.style.animationDuration = sec + 's';
});
#plus{
font-size: 60px;

position: relative;

A: I think this can fail because of this line
var sec= 5 + "s";
this line will execute always when you click on the button, so after that in "if" condition you will always get sec = '5s' and than it will be decreased to '4s'.
If you want that code to work, you could place "var sec = 5+'s' above the listener declaration. | unknown | |
d8378 | train | Your logic is a bit suspect in if grosspay > range(1000, 1500). What would it mean to be "greater" than a range of numbers? my guess is that the grosspay you input is, in fact, within the range [1000, 1500), so it hits this logic bug in your code and fails to assign it to anything.
The usual way to check if a number is within a range is to use the in operator.
if some_num in range(1, 10):
print("some_num is 1, 2, 3, 4, 5, 6, 7, 8, or 9")
However you'll notice that some_num MUST be contained in the integer range [1, 9] for this to trigger. If some_num is 7.5, this will fail. This is incredibly likely in the case of gross pay. What are the chances of someone's pay coming out to an exactly even dollar amount?
Instead what you could do is:
if grosspay <= 1000:
taxrate = 0.90
elif 1000 < grosspay <= 1500:
taxrate = 0.78
elif 1500 < grosspay:
taxrage = 0.63
using elif instead of a series of ifs makes the code slightly more efficient, since if/elif/else is by definition one block that is mutually exclusive. In other words:
a = 1
b = 2
if a == 1:
print("This gets done!")
if b == 2:
print("This gets done!")
if a == 1:
print("This gets done!")
elif b == 2:
print("BUT THIS DOESN'T!")
else:
print("(this doesn't either...)") | unknown | |

Browser support is limited to modern browsers though.
You can play around using this tool : http://bennettfeely.com/clippy/
A: Here's a solution that uses transforms to accomplish the desired corner effect. Although the solution is more complicated than the accepted one, it can be implemented on pretty much all modern browsers. By using several of the transform polyfills, the solution can be implemented across the board.
The algorithm behind this solution achieves a corner element via skewX() transform that is equally applied on the image (set as a background) and its container, just in different directions (e.g., -63.43deg and 63.43deg, depending on the dimensions of the corner element). Then the generated corner element is perfectly aligned with the heading's background.
Here's a fiddle: http://jsfiddle.net/bLbt11a3/.

*Containers provide a means to center and horizontally pad your
site’s contents. Use .container for a responsive pixel width or
.container-fluid for width: 100% across all viewport and device
sizes.
*Rows are wrappers for columns. Each column has horizontal padding
(called a gutter) for controlling the space between them. This
padding is then counteracted on the rows with negative margins. This
way, all the content in your columns is visually aligned down the
left side.
*In a grid layout, content must be placed within columns and only
columns may be immediate children of rows.

d8383 | train | You can not use session_start() or header() after content has been sent to the browser (<!DOCTYPE html> in your case).
Here, even if you are using ob_start() to buffer the output, what came before has not been buffered and is sent to the browser, which prevents header() and session_start() from working.
From the PHP documentation :
To use cookie-based sessions, session_start() must be called before outputting anything to the browser.
Remember that header() must be called before any actual output is sent, either by normal HTML tags, blank lines in a file, or from PHP.
The fact that it works on your local computer but not on your Web hosting provider's server is most likely due to differences between your configuration of PHP or of your Web server. For instance, output buffering may be enabled by default on your local installation (output_buffering = 4096 for instance), and be disabled on your Web hosting (output_buffering = Off). | unknown | |
d8384 | train | Can I define easier location for my published app.
Well inside of your connection string you can specify the location of the database under Data Source.
Take your database and move it where ever you want, and then update the Data Source inside of your connection string to point to that path. You might have to play with it a few times to get the path right, but this should do what you are wanting to do.
VB.net seem to place my database file into /userprofile/local settings/apps/2.0/data/random/random/appname/data/ folder.
If you are making an installer then you will want to keep the database close to the application, most likely inside a sub-folder in the application's directory (like the data folder). That is why VS (not VB .Net) tends to place a created database inside of the data folder. | unknown | |
d8385 | train | In SQLite, autoincrementing fields are intended to be used as actual primary keys for their records.
You should just it as the ID for your orders table.
If you really want to have an atomic counter independent of corresponding table records, use a table with a single record.
ACID is ensured with transactions:
BEGIN;
SELECT number FROM MyTable;
UPDATE MyTable SET number = ? + 1;
COMMIT;
A: ok, looks like sqlite either doesn't have what I need, or I am missing it. Here's what I came up with:
*
*declare zorder as integer primary key autoincrement, zuid integer in orders table
this means every new row gets an ascending number, starting with 1
*generate a random number:
rnd = int(random.random() * 1000000) # unseeded python uses system time
*create new order (just the SQL for simplicity):
'INSERT INTO orders (zuid) VALUES ('+str(rnd)+')'
*find that exact order number using the random number:
'SELECT zorder FROM orders WHERE zuid = '+str(rnd)
*pack away that number as the new order number (newordernum)
*clobber the random number to reduce collision risks
'UPDATE orders SET zuid = 0 WHERE zorder = '+str(newordernum)
...and now I have a unique new order, I know what the correct order number is, the risk of a read collision is reduced to negligible, and I can prepare that order without concern that I'm trampling on another newly created order.
Just goes to show you why DB authors implement sequences, lol. | unknown | |
d8386 | train | I think you asked this question before, and its also quite clear from your code sample that you are using GSView, not Ghostscript.
Now, while GSView does use Ghostscript to do the heavy lifting, its a concern that you are unable to differentiate between these two applications.
You still haven't provided an example PDF file to look at, nor a command line, though you have now at least managed to quote the Ghostscript version. You need to also give a command line (no I'm not prepared to assemble it from reading your code) and you should try this from the command line, not inside your own application, in order to show that its not your application making the error.
You should consider upgrading Ghostscript to the current version.
Note that a quick perusal of your code indicates that you are specifying a number of command line options (eg -dPDFSETTINGS) which are only appropriate for converting a file into PDF, not for any other purpose (such as printing).
So as I said before, provide a specimen file to reproduce the problem, and a command line (preferably a Ghostscript command line) which causes the problem. Knowing which printer you are using would probably be useful too, although its highly unlikely I will have a duplicate to test on.
A: Answer - UPDATE 16/12/2013
I was managed to get it fixed and wanted to enclose the working solution if it help others. Special thanks to 'KenS' since he spent lot of time to guide me.
To summarize, I finally decided to use GSView along with GhostScript to print PDF to bypass Adobe. The core logic is given below;
//PrintParamter is a custom data structure to capture file related info
private void PrintDocument(PrintParamter fs, string printerName = null)
{
if (!File.Exists(fs.FullyQualifiedName)) return;
var filename = fs.FullyQualifiedName ?? string.Empty;
printerName = printerName ?? GetDefaultPrinter(); //get your printer here
var processArgs = string.Format("-dAutoRotatePages=/All -dNOPAUSE -dBATCH -sPAPERSIZE=a4 -dFIXEDMEDIA -dPDFFitPage -dEmbedAllFonts=true -dSubsetFonts=true -dPDFSETTINGS=/prepress -dNOPLATFONTS -sFONTPATH=\"C:\\Program Files\\gs\\gs9.10\\fonts\" -noquery -dNumCopies=1 -all -colour -printer \"{0}\" \"{1}\"", printerName, filename);
try
{
var gsProcessInfo = new ProcessStartInfo
{
WindowStyle = ProcessWindowStyle.Hidden,
FileName = gsViewEXEInstallationLocation,
Arguments = processArgs
};
using (var gsProcess = Process.Start(gsProcessInfo))
{
gsProcess.WaitForExit();
}
}
A: You could use GSPRINT.
I've managed to make it work by only copying gsprint.exe/gswin64c.exe/gsdll64.dll in a directory and launch it from there.
sample code :
// This uses gsprint (mind the paths)
private const string gsPrintExecutable = @"C:\gs\gsprint.exe";
private const string gsExecutable = @"C:\gs\gswin64c.exe";
string pdfPath = @"C:\myShinyPDF.PDF"
string printerName = "MY PRINTER";
string processArgs = string.Format("-ghostscript \"{0}\" -copies=1 -all -printer \"{1}\" \"{2}\"", gsExecutable, printerName, pdfPath );
var gsProcessInfo = new ProcessStartInfo
{
WindowStyle = ProcessWindowStyle.Hidden,
FileName = gsPrintExecutable ,
Arguments = processArgs
};
using (var gsProcess = Process.Start(gsProcessInfo))
{
gsProcess.WaitForExit();
}
A: Try the following command within Process.Start():
gswin32c.exe -sDEVICE=mswinpr2 -dBATCH -dNOPAUSE -dNOPROMPT -dNoCancel -dPDFFitPage -sOutputFile="%printer%\\[printer_servername]\[printername]" "[filepath_to_pdf]"
It should look like this in C#:
string strCmdText = "gswin32c.exe -sDEVICE=mswinpr2 -dBATCH -dNOPAUSE -dNOPROMPT -dNoCancel -dPDFFitPage -sOutputFile=\"%printer%\\\\[printer_servername]\\[printername]\" \"[filepath_to_pdf]\"";
System.Diagnostics.Process.Start("CMD.exe", strCmdText);
This will place the specified PDF file into the print queue.
Note- your gswin32c.exe must be in the same directory as your C# program. I haven't tested this code. | unknown | |
d8387 | train | Android Studio doesn't read environment variables, so this approach won't work. Also, using the projectDir scheme in settings.gradle will probably cause problems. Android Studio has a limitation that all of its modules need to be located underneath the project root. If you have libraries that are used in multiple projects and they can't be placed under a single project root, the best advice is to have them publish JARs or AARs to a local Maven repository that individual projects can pick up.

*The ability for a client application to connect is almost entirely unrelated to the state of a sender channel. (I say almost because theoretically you could use up all the resources in your queue manager by having loads of retrying senders and then maybe they could affect clients).
*When a client application makes a connection to a queue manager, the network connection is first caught by the listener, and then a running channel of type SVRCONN is started. This is a different type from a SENDER channel, and so there is no requirement to have a SENDER channel running for the client connection to be successful.
*Sender channel status does not matter for the client to be able to connect.
Lets' try to diagnose your two problems. Look in the queue manager AMQERR01.LOG (found in the data directory under \Qmgrs\<qm-name>\errors) and edit your question to add the errors you see in there. There should be errors that explain why the sender channel is retrying, and some to explain why the client cannot connect.
It is possible that the problem with the client not being able to connect is because it is not even reaching the queue manager machine - in which case there will be nothing about that in the queue manager error log. In this case, you should also look in the AMQERR01.LOG on the client machine, this time in the data directory just under the errors folder (as no queue manager name there). You should also have seen some sort of error message or MQRC Reason code from the client application - you should tell us that too. | unknown | |

d8391 | train | If malloc() returns NULL it means that the allocation was unsuccessful. It's up to you to deal with this error case. I personally find it excessive to exit your entire process because of a failed allocation. Deal with it some other way.
A: In library code, it's absolutely unacceptable to call exit or abort under any circumstances except when the caller broke the contact of your library's documented interface. If you're writing library code, you should gracefully handle any allocation failures, freeing any memory or other resources acquired in the attempted operation and returning an error condition to the caller. The calling program may then decide to exit, abort, reject whatever command the user gave which required excessive memory, free some unneeded data and try again, or whatever makes sense for the application.
In all cases, if your application is holding data which has not been synchronized to disk and which has some potential value to the user, you should make every effort to ensure that you don't throw away this data on allocation failures. The user will almost surely be very angry. It's best to design your applications so that the "save" function does not require any allocations, but if you can't do that in general, you might instead want to perform frequent auto-save-to-temp-file operations or provide a way of dumping the memory contents to disk in a form that's not the standard file format (which might for example require ugly XML and ZIP libraries, each with their own allocation needs, to write) but instead a more "raw dump" which you application can read and recover from on the next startup.
A: Use Both?
It depends on whether the core file will be useful. If no one is going to analyze it, then you may as well simply _exit(2) or exit(3).
If the program will sometimes be used locally and you intend to analyze any core files produced, then that's an argument for using abort(3).
You could always choose conditionally, so, with --debug use abort(3) and without it use exit. | unknown | |
d8392 | train | Am not really fond of playing with points and Superview. What is can suggest is to make a class for UITapGestureRecognizer as follows which can hold extra data. In your case it would be an index path
class CustomGesture: UITapGestureRecognizer {
let indexPath:NSIndexPath? = nil
}
And then in your didSelect you can add the index path to the newly created CustomGesture class which be would be like:
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
{
cell.imageView.userInteractionEnabled = true
let tapImageView = CustomGesture(target: self, action: #selector(HomeFeedViewController.tapImageView(_:)))
tapImageView.indexPath = indexPath// Add the index path to the gesture itself
cell.imageView.addGestureRecognizer(tapImageView)
return cell as CastleCell
}
Now since you have added the indexPath you don't need to play around with super view's and you can access the cell like this:
func tapImageView(gesture: CustomGesture) {
let indexPath = gesture.indexPath!
let cell = self.tableView.cellForRowAtIndexPath(indexPath!) as! CastleCell

d8396 | train | I've figured out the answer for this:
When jQuery loads, it assigns an event handler to the $(".accordion .accordion-trigger-all.open").on('click', function() so at the beginning it only finds whichever is open. However when it searches again it doesn't find the element with the class removed.
Simple solution: $(".accordion").on('click','.accordion-trigger-all.open', function()
which will add the event handler to the whole element, instead of the only the element with the class .open
The same should be done for the opposite: $(".accordion").on('click','.accordion-trigger-all:not(.open)', function() | unknown | |

HttpContext is only available at server side, so my previous answer was incorrect as pointed by Phil.
The correct way to do it would be rather clumsy as you have get hold of HttpRequest itself

Things to look out for in your css? floats that haven't been cleared for example.
Things to look out for in the Html? Unclosed tags.
You can diagnose the above kind of problem by right clicking on the offending area and doing "Inspect Element" when viewing the page in either Google Chrome or FireFox?
Are you assigning css classes using jquery or similar? Probably not, given your inline js code in the a tag...
All the above or a combination thereof are possible candidates, but in the absence of a page to look at, your not going to get much help.
A: I may not be correct but what i interpreted from the description is you are appending some HTML from code behind into your place holder.
If it is possible you can append the elements into your div
through jquery.
$('div.warning').append("your content")
A: Just guessing here, are you overriding the page's render method? And ff you try and change the containing div to runat="server" what happens? | unknown | |
d8399 | train | I have done some research into fast KD-tree implementations a few months ago, and I agree with Anony-Mousse that quality (and "weight" of libraries) varies strongly. Here are some of my findings:
kdtree2 is a little known and pretty straightforward KD-tree implementation I found to be quite fast for 3D problems, especially if you allow it to copy and re-sort your data. Also, it is small and very easy to incorporate and adapt. Here is a paper on the implementation by the author (don't be put off by the mentioning of Fortran in the title). This is the library I ended up using. My colleagues benchmarked its speed for 3D points against VLFeat's KD-trees and another library I don't remember (many FLANN, see below) and it won.
FLANN has a reputation of being fast, and is used and recommended quite often recently. It aims at the higher dimensional case, where it offers approximate algorithms, but is also used in the Point Cloud Library which deals with 3D problems.
I did not experiment with CGAL since I found the library to be too heavyweight. I agree that CGAL has a good reputation, but I feel it occasionally suffers from oversophistication.
A: From my experience, implementation quality varies widely, unfortunately. I have, however, never looked at the CGAL implementation.
The worst case for the k-d-tree usually is when due to incremental changes it becomes too unbalanced, and should be reloaded.
However, in general such trees are most efficient when you don't know the data distribution.
In your case it sounds as if a simple grid-based approach may be the best choice. If you want, you can consider a texture to be a dense 2d grid. So maybe you can find a 2d projection where a grid works good, and then intersect with this projection.
A: Answers are not the place to ask questions, but your question is not a question, but a statement that the kd-tree of CGAL sucks.
Reading 1.8mio points of a geological data model, and computing the 50 clostest points for each of these points has the following performance on my Dell Precision, Windows7, 64bit, VC10:
*
*reading the points from a file: 10 sec
*Construction of the tree 1.3 sec
*1.8 mio queries reporting the 50 closest points: 17 sec
Do you have similar performances. Would you expect a kd-tree to be faster?
Also I am wondering where your query points are, that is close to the surface, or close to the skeleton.
A: Take a look at ApproxMVBB library under the MPL licence:
https://github.com/gabyx/ApproxMVBB:
The kdTree implementation should be comparable to PCL(FLANN) and might be even faster. (tests with PCL seemed to be faster with my implementation!)
Diclaimer: I am the owner of this library and by no means this library claims to be any faster and serious performance tests have not been conducted yet, but I am using this library sucessfully in granular rigid body dynamics where speed is king!
However, this library is very small, and the kdTree implementation is very generic (see the examples) and lets you have custom splitting heurstics and other fancy stuff :-).
Similar improvements and considerations as in the nanoflann (direct data access etc., generic data, n-dimensional ) are implemented ... (see the KdTree.hpp) header.

Take care about the interpretation! and look at the settings used in the example File.
However comparing with results from other people: ~3100ms for 14*10⁶ points is quite slick :-)

A: If the kdtree is fast for small sets, but "slow" for large (>100000?) sets, you may be suffering from flushing the processor caches. If the top few nodes are interleaved with rarely used leaf nodes then you will fit fewer heavily used nodes in the processor cache(s). This can be improved by minimising the size of the nodes and careful layout of the nodes in memory.. but eventually you will be flushing a fair number of nodes anyway. You can end up with access to main memory being the bottle-neck.
Valgrind tells me one version of my code is 5% fewer instructions, but I believe the stopwatch when it tells me it is about 10% slower for the same input. I suspect valgrind doing a full cache simulation would tell me the right answer.
If you are multi-threaded, you may want to encourage the threads to be doing searches in similar areas to reuse the cache... that assumes a single multi-core processor - multiple processors might want the opposite approach.
Hint: You pack more 32bit indexes in memory than 64bit pointers. | unknown | |
