Flask-WTF: CSRF token missing | <p>What seemed like a simple bug - a form submission that won't go through due to a "CSRF token missing" error - has turned into a day of hair pulling. I have gone through every SO article related to Flask or Flask-WTF and missing CSRF tokens, and nothing seems to be helping. </p>
<p>Here are the details:</p>
<p>Following <a href="https://stackoverflow.com/a/21501593/5578714" title="Martijin's guidelines">Martijin's guidelines</a> to an earlier question:</p>
<blockquote>
<p>The Flask-WTF CSRF infrastructure rejects a token if:</p>
<p>1) the token is missing. Not the case here, you can see the token in the form.</p>
</blockquote>
<p>The token is definitely present in my form, and being POST'ed successfully</p>
<blockquote>
<p>2) it is too old (default expiration is set to 3600 seconds, or an hour).
Set the TIME_LIMIT attribute on forms to override this. Probably not the
case here.</p>
</blockquote>
<p>Also OK for me - the token is well within the default expiration time </p>
<blockquote>
<p>3) if no 'csrf_token' key is found in the current session. You can
apparently see the session token, so that's out too.</p>
</blockquote>
<p>In my case, session['csrf_token'] is properly set and seen by Flask</p>
<blockquote>
<p>4) If the HMAC signature doesn't match; the signature is based on the
random value set in the session under the 'csrf_token' key, the
server-side secret, and the expiry timestamp in the token.</p>
</blockquote>
<p><strong>This is my problem</strong>. The HMAC comparison between the submitted form's CSRF and the session CSRF fails. And yet I don't know how to solve it. I've been desperate enough (as with the other questioner) to dig into Flask-WTF code and set debugging messages to find out what's going on. As best I can tell, it's working like this:</p>
<p>1) <code>generate_csrf_token()</code> in "form.py" (Flask-WTF) wants to generates a CSRF token. So it calls:</p>
<p>2) <code>generate_csrf()</code> in "csrf.py". That function generates a new session['csrf_token'] if one does not exist. <strong>In my case, this always happens</strong> - although other session variables appear to persist between requests, my debugging shows that I <strong>never</strong> have a 'csrf_token' in my session at the start of a request. Is this normal?</p>
<p>3) The generated token is returned and presumably incorporated into the form variable when I render hidden fields on the template. (again, debugging shows that this token is present in the form and properly submitted and received)</p>
<p>4) Next, the form is submitted.</p>
<p>5) Now, <code>validate_csrf</code> in csrf.py is called. But since another request has taken place, and generate_csrf() has generated a new session CSRF token, the two timestamps for the two tokens (in session and from the form) will not match. And since the CSRF is made up in part by expiration dates, therefore validation fails.</p>
<p>I suspect the problem is in step #2, where a new token is being generated for every request. But I have no clue why <strong>other</strong> variables in my session are persisting from request to request, but not "csrf_token".</p>
<p>There is no weirdness going on with SECRET_KEY or WTF_CSRF_SECRET_KEY either (they are properly set).</p>
<p>Anyone have any ideas?</p> | 0 |

Angular 2 Unit Tests: Cannot find name 'describe' | <p>I'm following <a href="https://angular.io/docs/ts/latest/guide/testing.html#!#jasmine-101" rel="noreferrer">this tutorial from angular.io</a></p>
<p>As they said, I've created hero.spec.ts file to create unit tests:</p>
<pre><code>import { Hero } from './hero';
describe('Hero', () => {
it('has name', () => {
let hero: Hero = {id: 1, name: 'Super Cat'};
expect(hero.name).toEqual('Super Cat');
});
it('has id', () => {
let hero: Hero = {id: 1, name: 'Super Cat'};
expect(hero.id).toEqual(1);
});
});
</code></pre>
<p>Unit Tests work like a charm. The problem is: I see some errors, which are mentioned in tutorial:</p>
<blockquote>
<p>Our editor and the compiler may complain that they don’t know what <code>it</code>
and <code>expect</code> are because they lack the typing files that describe
Jasmine. We can ignore those annoying complaints for now as they are
harmless.</p>
</blockquote>
<p>And they indeed ignored it. Even though those errors are harmless, it doesn't look good in my output console when I receive bunch of them.</p>
<p>Example of what I get:</p>
<blockquote>
<p>Cannot find name 'describe'.</p>
<p>Cannot find name 'it'.</p>
<p>Cannot find name 'expect'.</p>
</blockquote>
<p>What can I do to fix it?</p> | 0 |
Using docker-compose to set containers timezones | <p>I have a docker-compose file running a few Dockerfiles to create my containers. I don't want to edit my Dockerfiles to set timezones because they could change at any time by members of my team and I have a docker-compose.override.yml file to make local environment changes. However, one of my containers (a Selenium based one) seems to not pull host time zone and that causes problems for me. Based on that I want to enforce timezones on all my containers. In my Dockerfiles right now I do</p>
<pre><code>ENV TZ=America/Denver
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone
</code></pre>
<p>And everything works fine. How do I replicate the same command in docker-compose syntax?</p> | 0 |

access host's ssh tunnel from docker container | <p>Using ubuntu tusty, there is a service running on a remote machine, that I can access via port forwarding through an ssh tunnel from <code>localhost:9999</code>.</p>
<p>I have a docker container running. I need to access that remote service via the host's tunnel, from within the container.</p>
<p>I tried tunneling from the container to the host with <code>-L 9000:host-ip:9999</code> , then accessing the service through <code>127.0.0.1:9000</code> from within the container fails to connect. To check wether the port mapping was on, I tried
<code>
nc -luv -p 9999 # at host
nc -luv -p 9000 # at container
</code></p>
<p>following <a href="http://www.binarytides.com/netcat-tutorial-for-beginners/" rel="noreferrer">this, parag. 2</a> but there was no perceived communication, even when doing
<code>
nc -luv host-ip -p 9000
</code> at the container</p>
<p>I also tried mapping the ports via <code>docker run -p 9999:9000</code> , but this reports that the bind failed because the host port is already in use (from the host tunnel to the remote machine, presumably).</p>
<p>So my questions are</p>
<p>1 - How will I achieve the connection? Do I need to setup an ssh tunnel to the host, or can this be achieved with the docker port mapping alone?</p>
<p>2 - What's a quick way to test that the connection is up? Via bash, preferably.</p>
<p>Thanks.</p> | 0 |

Removing Duplicates From Array of Custom Objects Swift | <p>I have a custom class defined as follows : </p>
<pre><code>class DisplayMessage : NSObject {
var id : String?
var partner_image : UIImage?
var partner_name : String?
var last_message : String?
var date : NSDate?
}
</code></pre>
<p>Now I have an array <code>myChats = [DisplayMessage]?</code>. The <code>id</code> field is unique for each <code>DisplayMessage</code> object. I need to check my array and remove all duplicates from it, essentially ensure that all objects in the array have a unique <code>id</code>. I have seen some solutions using <code>NSMutableArray</code> and <code>Equatable</code> however I'm not sure how to adapt them here; I also know of <code>Array(Set(myChats))</code> however that doesn't seem to work for an array of custom objects.</p> | 0 |
Is there a way to use javascript variable inside Laravel blade template? | <p>I will automatically create the rows of a table in jQuery . by clicking addRow button , function addRow() will do it like below:</p>
<pre><code>function addRow(){
var rowCount = $("table tr").length - 1;
var row = '<tr><td><input name=“item[‘+ (rowCount+1) + ']" type="text" value="{{ old(‘item') }}”> @if ($errors->has(‘item’)){{ $errors->first(‘item’) }}@endif<td></tr>' ;
$("table").append(row);
}
</code></pre>
<p>I will call this method 5 times and it will create 5 input areas which name are item1. item2, item3, item4, item5.</p>
<p>in server side ,I use Laravel 5.2 Form Request Validation to validate every input field. </p>
<p>But if the validation failed , the old input and error will not set to the correct input field because </p>
<p>I can’t put the javascript variable rowCount into "{{ old(‘item') }}” which is a blade template.
and the same is {{ $errors->first(‘item’) }}.</p>
<p>I tried to write like this </p>
<pre><code>'value="{{ old('giftValue[' . $rowCount .']') }}">'
</code></pre>
<p>and this</p>
<pre><code>'value="{{ old('giftValue[' + $rowCount +’]’) }}">'
</code></pre>
<p>but does’t work.</p>

searching gridview in asp.net C# | <p>I am trying to look for a way to search a grid view in asp.net using C# programming language. I dont want the grid view to have paging enabled.

<p>I have looked up on some sites which have databind in the code. </p>
<pre><code>GridView1.DataSource = dt;
GridView1.DataBind();

<p>Do I need to have this? What does this do? </p>
<p>Can I please get some help with advice or links that can answer my question. Thank you. </p> | 0 |

C# WPF Indeterminate progress bar | <p>Please could someone suggest why the following doesn't work? All I want to do is display an indeterminate progress bar which starts when the button is clicked, then after I've done some work I set the indeterminate progress bar to false to stop it.</p>
<p>However when I run the code below the indeterminate progress bar doesn't even start. I tried commenting out the line <code>this.progressBar.IsIndeterminate = false</code> and when I do this the progress bar does start but then doesn't terminate.</p>
<pre><code>private void GenerateCSV_Click(object sender, RoutedEventArgs e)
{
this.Dispatcher.Invoke(DispatcherPriority.Normal, new Action(delegate ()
{
this.progressBar.IsIndeterminate = true;
// do some work
Thread.Sleep(10 * 1000);
this.progressBar.IsIndeterminate = false;
}));

Jenkins multibranch pipeline with Jenkinsfile from different repository | <p>I have a Git repository with code I'd like to build but I'm not "allowed" to add a <code>Jenkinsfile</code> in its root (it is a Debian package so I can't add files to upstream source). Is there a way to store the <code>Jenkinsfile</code> in one repository and have it build code from another repository? Since my code repository has several branches to build (one for each Debian release) this should be a multibranch pipeline. Commits in either the code or <code>Jenkinsfile</code> repositories should trigger a build.</p>
<p><strong>Bonus complexity:</strong> I have several code/packaging repositories like this and I'd like to reuse the same <code>Jenkinsfile</code> for all of them. Thus it should somehow dynamically fetch the right Git URL to use. The branches to build have the same names across all repositories.</p> | 0 |
How to use VBA to add new record in MS Access? | <p>I'm using bound forms for the user to update information on new or existing customers. Right now I'm using a Add New Record macro on the submit button (because I'm not sure how to add or save a new record through VBA). </p>
<p>I added a before update event (using VBA) to have the user confirm they want to save changes before exiting the form. For some reason this is overriding the add record button and now users cannot add new record until exiting the forms.</p>
<p>How can I use VBA to add new customer information to the correct table? Is this something that should be done with macros instead?</p>

strmsg = "Data has been changed."
strmsg = strmsg & " Save this record?"

geom_text overlapping with data points despite using nudge_x and nudge_y | <p>I'm trying to have text labels not overlap with the data points in a scatterplot made in <code>ggplot2</code>.</p>

Angular 2 reload route on param change | <p>I am currently writing my first Angular 2 Application.
I have an OverviewComponent which has the following simple template:</p>
<pre><code><div class="row">
<div class="col-lg-8">
<router-outlet></router-outlet>
</div>
<div class="col-lg-4">
<app-list></app-list>
</div>
</div>
</code></pre>
<p>when accessing the url <code>/</code> my router redirects me to <code>/overview</code> which then loads a map within the router-outlet. The <code><app-list></code> has a list of clickable items which triggers a <code><app-detail></code> to be displayed instead of the app component. Therefor I pass the id of the referring json file in the url like that: <code>/details/:id</code> (in my routes).</p>
<p>All of the above works totally fine. If I now click on one of the list items the details are shown, BUT when I select another list element the view doesn't change to the new details. The URL does change but the content is not reloaded. How can I achieve a Reinitialization of the DetailComponent?</p> | 0 |
Use None instead of np.nan for null values in pandas DataFrame | <p>I have a pandas DataFrame with mixed data types. I would like to replace all null values with None (instead of default np.nan). For some reason, this appears to be nearly impossible. </p>
<p>In reality my DataFrame is read in from a csv, but here is a simple DataFrame with mixed data types to illustrate my problem. </p>
<pre><code>df = pd.DataFrame(index=[0], columns=range(5))
df.iloc[0] = [1, 'two', np.nan, 3, 4]
</code></pre>
<p>I can't do:</p>
<pre><code>>>> df.fillna(None)
ValueError: must specify a fill method or value
</code></pre>
<p>nor:</p>
<pre><code>>>> df[df.isnull()] = None
TypeError: Cannot do inplace boolean setting on mixed-types with a non np.nan value
</code></pre>
<p>nor:</p>
<pre><code>>>> df.replace(np.nan, None)
TypeError: cannot replace [nan] with method pad on a DataFrame
</code></pre>
<p>I used to have a DataFrame with only string values, so I could do:</p>
<pre><code>>>> df[df == ""] = None
</code></pre>
<p>which worked. But now that I have mixed datatypes, it's a no go.</p>
<p>For various reasons about my code, it would be helpful to be able to use None as my null value. Is there a way I can set the null values to None? Or do I just have to go back through my other code and make sure I'm using np.isnan or pd.isnull everywhere? </p> | 0 |

Adjusting the container div's size to exactly fit the rendered React component | <p>I am trying to render a component whose style and position are determined based on some cases.

How can I visualize a histogram with Promdash or Grafana? | <p>I'm attracted to prometheus by the histogram (and summaries) time-series, but I've been unsuccessful to display a histogram in either promdash or grafana. What I expect is to be able to show:</p>

<li>a histogram at a point in time, e.g. the buckets on the X axis and the count for the bucket on the Y axis and a column for each bucket</li>
<li>a stacked graph of the buckets such that each bucket is shaded and the total of the stack equals the inf bucket</li>
</ul>

Set KeyPressed event for a TextField in JavaFX | <p>I have number of <code>TextField</code> objects inside a pop up window called dialog (type : <code>Stage</code>).</p>

if (keyCode == KeyCode.ESCAPE ){
dialog.close();
System.out.println("escape got called");

textwp.setOnAction((event) -> {escapeKeyPressed(KeyCode.ESCAPE ,dialog );});
textState.setOnAction((event) -> {escapeKeyPressed(KeyCode.ESCAPE ,dialog );});
textloginName.setOnAction((event) -> {escapeKeyPressed(KeyCode.ESCAPE ,dialog );});

Merge two objects with ES6 | <p>I'm sure this question has been asked before but I can't quite find the answer I'm looking for, so here goes:</p>
<p>I have two objects, as follows:</p>
<pre><code>const response = {
lat: -51.3303,
lng: 0.39440
}
let item = {
id: 'qwenhee-9763ae-lenfya',
address: '14-22 Elder St, London, E1 6BT, UK'
}
</code></pre>
<p>I need to merge these together to form this:</p>
<pre><code>item = {
id: 'qwenhee-9763ae-lenfya',
address: '14-22 Elder St, London, E1 6BT, UK',
location: {
lat: -51.3303,
lng: 0.39440
}
}
</code></pre>
<p>I know I could do it like this:</p>
<pre><code>item.location = {}
item.location.lat = response.lat
item.location.lng = response.lng
</code></pre>
<p>However, I feel that this is not the best way to do it anymore, because ES6 introduced the cool destructuring/assignment stuff; I tried deep object merging but it's unfortunately not supported :( I also looked through some ramda functions but couldn't see anything that was applicable.</p>
<p>So what is the best way to merge these two objects using ES6? </p> | 0 |
Comparing two timestamps in php | <p>SO the scene is, I have a store which opens at 1:00am at night, and closes at 10:00pm.
For any current time i just want to check whether that timestamp lies between store open and close times.</p>
<p>Yeap that's very simple, and still I don't know why, am finding it difficult.
below is a piece of epic shit i am trying.</p>
<pre><code><?php
$t=time(); //for current time
$o = date("Y-m-d ",$t)."01:00:00"; //store open at this time
$c = date("Y-m-d ",$t)."22:00:00"; //store closes at this time
//Yes, its crazy .. but I love echoing variables
echo "current time = ".$t;
echo PHP_EOL;
echo "Start = ".strtotime($o);
echo PHP_EOL;
echo "End = ".strtotime($c);
echo PHP_EOL;
// below condition runs well, $t is always greater than $o
if($t>$o){
echo "Open_c1";
}else{
echo "Close_c1";
}
//Here's where my variable $t, behaves like a little terrorist and proclaims itself greater than $c
if($t<$c){
echo "Open_c2";
}else{
echo "Close_c2";
}
?>
</code></pre>
<p>OUTPUT: on phpfiddle</p>
<p>current time = 1472765602 Start = 1472706000 End = 1472781600 Open_c1 Close_c2</p>
<p>Just one help, why ( $t < $c ) condition is false.
Am I missing something very common or making a serious blunder.</p>

<p>If a change a radio I see that the value changes to true for false:</p>
<pre><code><pre> {{model_parameters_general.estimationmethod=='ew'}} </pre>
</code></pre>
<p>So wow why will the input box be disabled based on true for false?</p>
<pre><code><input [disabled]="model_parameters_general.estimationmethod=='ew'" [(ngModel)]="model_parameters_general.lambda"
formControlName="lambda" type="text" class="form-control">
</code></pre>
<p>EDIT:</p>
<p>In the logs I get this:</p>
<pre><code>It looks like you're using the disabled attribute with a reactive form directive. If you set disabled to true
when you set up this control in your component class, the disabled attribute will actually be set in the DOM for
you. We recommend using this approach to avoid 'changed after checked' errors.
Example:
form = new FormGroup({
first: new FormControl({value: 'Nancy', disabled: true}, Validators.required),
last: new FormControl('Drew', Validators.required)
});
</code></pre>
<p>So I am using a reactive from in rc6. </p>
<p>I set the initial disable to the below:</p>
<pre><code>this.myForm = fb.group({
lambda: new FormControl({value: .99, disabled: true}, Validators.required),
})
</code></pre>
<p>So do I enable based on a toggle of a radio input?</p> | 0 |

How can I add Font Awesome to my Aurelia project using npm? | <p>I have been following the <a href="http://aurelia.io/hub.html#/doc/article/aurelia/framework/latest/contact-manager-tutorial" rel="noreferrer">Contact Manager</a> tutorial and would like to add <em>Font Awesome</em> to the project. Here's what I have done so far:</p>
<ul>
<li><code>npm install Font-Awesome --save</code></li>
<li>Added the following to <code>aurelia.json</code>under the <em>dependencies</em> array of the <code>vendor-bundle.js</code>:</li>
</ul>
<p><br></p>

"name": "font-awesome",
"path": "../node_modules/font-awesome",

How to block ads with HTML/JS? | <p>I have a site (<a href="http://forum.tdp4teambattle.com" rel="nofollow">forum.tdp4teambattle.com</a>) and recently, I started getting ads in the footer. I looked in the footer and there is no code for the ad. I'm thinking they put it in another file and specified it to a certain div ID. What code in HTML or JavaScript can I use to hide the ad so others don't see it?</p>
<p>Here is the ad image: <a href="http://is.mixmarket.biz/images/um/95480.gif" rel="nofollow">http://is.mixmarket.biz/images/um/95480.gif</a>
it is 468x60 (maybe you can give me a code to block images of that specific size from showing up).</p>
<p>Edit, solved: if anybody was using "listbb.ru" or "getbb.ru", here is the solution. You'll need to view source on your index page and do CTRL+F. Search for "mix", or "market" or similar. You will see something along the lines of "mix_block_{identifier}". To remove it, you'll need to navigate to ACP>Styles>Templates>{Theme}>Overall_header.html>
find </p>
<pre><code></head>
</code></pre>
<p>and before, enter:</p>
<pre><code><style>
#mix_block_1294937123 {
display: none;

How to clean old deployed versions in Firebase hosting? | <p>Every time you deploy to Firebase hosting a new deploy version is created so you can roll back and see who deployed. This means that each time every file you deploy is stored and occupying more space.</p>

Hibernate naming strategy changing table names | <p>I'm a little bit confused by hibernates (version 5.1) naming strategy - namely it changes my table name and I'd like to avoid that. Also - <code>spring.jpa.hibernate.naming_strategy</code> seems to be deprecated according to intelij, but I can't find a (nother) way of configuring it correctly.</p>
<p>I have the following configuration in application.properties:</p>
<pre><code>spring.jpa.hibernate.naming_strategy=org.hibernate.cfg.EJB3NamingStrategy
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
spring.jpa.properties.hibernate.enable_lazy_load_no_trans=true
spring.jpa.properties.hibernate.current_session_context_class=thread
</code></pre>
<p>The first one is marked as depracted, as said. </p>
<p>Now I have an entity:</p>
<pre><code>@Entity
@Table(name = "usaUploadTable", schema = "usertable201", catalog = "")
public class UsaUploadTable {
....
}
</code></pre>
<p>The table name is, like in <code>@Table(name = "")</code> usaUploadTable. </p>
<p>Now when I run my application, I get </p>
<blockquote>
<p>Table 'usertable201.usa_upload_table' doesn't exist</p>
</blockquote>
<p>which is correct - it isn't named like how hibernate is changing it. </p>
<p>What can I do to make hibernate use my table name correctly?</p>
<p>Edit: </p>
<p>I've also tried</p>
<pre><code>DefaultNamingStrategy
ImprovedNamingStrategy
</code></pre>
<p>All of them change it</p>
<p>Versions:</p>
<pre><code>spring-boot-1.4.0.RELEASE
hibernate 5.1
javax-transaction-api 1.2
hibernate-validator 5.2.4
javassist 3.20

Can you set the qDebug() floating point precision and number format globally? | <p>I want to use qDebug(), qInfo() and so on with a custom default floating point precision and number format.</p>
<p>Is there a way to define this globally?</p>
<p>Imagine this: </p>
<pre><code>double num = 1.2;
qDebug() << "My floating point Number is: " << QString::number(num, 'f', 2);
//Output: My floating point Number is 1.20
</code></pre>
<p>Now I would like to avoid QString::number(num, 'f', 2) everytime I write a number and would much rather like to use a standard percision and format.</p> | 0 |

How to mock/create X509Certificate2 for unit testing? | <p>I have handler which creates jwt token with utilization of X509Certificate2. For unit test I need to provide certificate and it is not possible for me take it from the local store. Is there way, how to mock, create or load certificate from the file? </p>
<p>So far I tried BouncingCastle method from <a href="https://stackoverflow.com/questions/2315257/how-to-create-a-completely-new-x509certificate2-in-net">this</a> ticket, but with no success. The method ToX509Certificate2() does convert certificate, but without keys. So if this is good way to go, is possible to generate these keys somehow?</p>

WebAPI error reading MIME multipart body part | <p>My team recently refactored a Web API service to move some of the repetitive code into static methods. One method is related to extracting an uploaded file from the request. The method works in unit testing, but under load, is throwing exceptions. Part of the code was found in an SO post, but I'm concerned that, overall, we're not using it correctly. Here's the code:</p>
<pre><code>internal static string ExtractFile(HttpRequestMessage request)
{
if (request.Content.IsMimeMultipartContent())
{
string uploadRoot = ServiceHelper.GetUploadDirectoryPath();
var provider = new MultipartFormDataStreamProvider(uploadRoot);
try
{
Task.Factory
.StartNew(() => provider = request.Content.ReadAsMultipartAsync(provider).Result,
CancellationToken.None,
TaskCreationOptions.LongRunning, // guarantees separate thread
TaskScheduler.Default)
.Wait();
}
catch(System.AggregateException ae)
{
if(log.IsErrorEnabled)
{
foreach(var ex in ae.InnerExceptions)
{
log.Error("ReadAsMultipartAsync task error.", ex);
}
}
var errorResponse = request.CreateErrorResponse(HttpStatusCode.InternalServerError, "An error occurred while extracting the uploaded file from the request.");
throw new HttpResponseException(errorResponse);
}
var fileData = provider.FileData.First();
var localName = fileData.LocalFileName;
var content = File.ReadAllText(localName);
if (log.IsDebugEnabled)
{
var embeddedName = fileData.Headers.ContentDisposition.FileName;
log.DebugFormat("File {0} was successfully uploaded as '{1}'.", embeddedName, localName);
}
return content;
}
else
{
log.Error("Invalid request received. Request must be in a multipart/form-data request.");
var errorResponse = request.CreateErrorResponse(HttpStatusCode.InternalServerError, "Request must be a multipart/form-data request and contain one file.");
throw new HttpResponseException(errorResponse);
}
}
</code></pre>
<p>Walking thru the logs, I see errors like these:</p>
<p>System.IO.IOException: Error reading MIME multipart body part. ---> System.IO.IOException ---> System.Net.HttpListenerException: The I/O operation has been aborted because of either a thread exit or an application request</p>
<p>HttpListenerRequest disposed</p>
<p>System.IO.IOException: Error reading MIME multipart body part. ---> System.IO.IOException ---> System.Net.HttpListenerException: An operation was attempted on a nonexistent network connection</p>
<p>This web service is running as a self-hosted OWIN Windows service. The file uploads are small (3k to 4k).</p>
<p>I can't recreate the issue with a single upload. The client that is talking to the service uses tasks to post files, but it doesn't usually run more than 4 or 5 tasks concurrently. My team and I are relatively new to .NET tasks. One of the developers is wondering if the TaskCreationOptions.LongRunning parameter is actually hurting more than it helps. Any suggestions?</p>
<p><strong>Update:</strong></p>
<p>I tried switching out the Task.Factory code with this:</p>
<pre><code>var task = Task.Run(async () => await request.Content.ReadAsMultipartAsync(provider));
task.Wait();
provider = task.Result;
</code></pre>
<p>I'm still having some issues, but this seems to work better. Not sure why, though.</p> | 0 |

Why in Scala Long cannot in initialized to null whear as Integer can | <p>I am creating my Scala bean which is a configuration to be loaded from a YML config. I want a long property to be null if not specified, but I'm facing below issue. Any idea why?</p>

difference between standard's atomic bool and atomic flag | <p>I wasn't aware of the <code>std::atomic</code> variables but was aware about the <code>std::mutex</code> (weird right!) provided by the standard; however one thing caught my eye: there are two seemingly-same (to me) atomic types provided by the standard, listed below:</p>
<ol>
<li><p><a href="http://en.cppreference.com/w/cpp/atomic/atomic" rel="noreferrer"><code>std::atomic<bool></code></a></p></li>
<li><p><a href="http://en.cppreference.com/w/cpp/atomic/atomic_flag" rel="noreferrer"><code>std::atomic_flag</code></a></p></li>
</ol>
<p>The <code>std::atomic_flag</code> contains the following explanation:</p>
<blockquote>
<p><code>std::atomic_flag</code> is an atomic boolean type. Unlike all specializations of <code>std::atomic</code>, it is guaranteed to be lock-free. Unlike <code>std::atomic<bool></code>, <code>std::atomic_flag</code> does not provide load or store operations.</p>
</blockquote>
<p>which I fail to understand. Is <code>std::atomic<bool></code> not guaranteed to be lock-free? Then it's not atomic or what?</p>
<p>So what's the difference between the two and when should I use which?</p> | 0 |
Tampermonkey script run before page load | <p>I need to hide a section from an html page:</p>
<pre><code><h1 data-ng-show="!menuPinned &amp;&amp; !isSaaS" class="logo floatLeft" aria-hidden="false"><span>XXX&nbsp;</span><span style="font-weight: bold;">XXX&nbsp;</span><span>XXXXX</span></h1>
</code></pre>
<p>The following code works fine in Chrome dev. tools</p>
<pre><code>var ibmlogo = document.querySelectorAll('h1.logo.floatLeft');
ibmlogo[1].remove();
</code></pre>
<p>But when I load the page with the script active, the section (h1) won't disappear.
I believe this is because when the script runs, the DOM has not been completed loaded yet, hence the script fails to find the selector.</p>
<p>I have tried many different things (e.g. window.onLoad) but still my script is not effective. Last attempt (failed) is the following:</p>
<pre><code>var logo = document.querySelectorAll('h1.logo.floatLeft');
logo.onload = function() {removeLogo()};
function removeLogo(){
console.log("### logo array lenght: " + logo.length);
logo[1].remove();
};

How to loop video with AVPlayerLooper | <p>I try to loop a video in a TV OS app with the <code>AVPlayerLooper</code> because this should get rid of the pause/hicup when playing the video again. I watched the <code>WWDC2016</code> video <a href="https://developer.apple.com/videos/play/wwdc2016/503/" rel="noreferrer">https://developer.apple.com/videos/play/wwdc2016/503/</a> and try to implement the code but it doesn't loop.
I have one <code>PlayerViewController</code> which inherits <code>AVPlayerViewController</code>. I put the code to let the video loop. If I have the following code, it shows nothing. If I change the second line to <code>self.queuePlayer = AVQueuePlayer(playerItem:playerItem)</code>, it only plays once. </p>
<pre><code> let playerItem = AVPlayerItem(url: url as URL)
self.queuePlayer = AVQueuePlayer() //I declared this as a variable in the view controller
self.playerLayer = AVPlayerLayer(player: self.queuePlayer) //I declared this as a variable in the view controller
let playerLooper = AVPlayerLooper(player: self.queuePlayer!, templateItem: playerItem)
self.view.layer.addSublayer(self.playerLayer!)
self.playerLayer?.frame = self.view.frame
self.queuePlayer?.play()
</code></pre>
<p>Have any of you succeeded in playing looped video with the latest <code>AVPlayerLooper</code>?</p> | 0 |

What does the := operator mean in mysql? | <p>I have a <code>mysql</code> table (<code>scho_id</code>,<code>school_name</code>,<code>school_views</code>). </p>
<p>I was looking for a <code>mysql</code> query to get <code>rank</code> of schools on the basis of <code>school_views</code>.</p>
<p>I found this solution on stackoverflow.</p>
<pre><code>SET @points := -1, @num := 0;
SELECT scho_id
, school_views
, @num := if(@points = school_views, @num, @num + 1) as school_rank
, @points := school_info.school_views as dummy
FROM school_info
ORDER BY school_views desc, scho_id asc;
</code></pre>
<p>This solved my problem but I notice a new operator <code>:=</code> in this query. I am curious to know the meaning and uses of this operator.</p> | 0 |
Calling "fit" multiple times in Keras | <p>I've working on a CNN over several hundred GBs of images. I've created a training function that bites off 4Gb chunks of these images and calls <code>fit</code> over each of these pieces. I'm worried that I'm only training on the last piece on not the entire dataset.</p>
<p>Effectively, my pseudo-code looks like this:</p>
<pre><code>DS = lazy_load_400GB_Dataset()
for section in DS:
X_train = section.images
Y_train = section.classes
model.fit(X_train, Y_train, batch_size=16, nb_epoch=30)
</code></pre>
<p>I know that the API and the Keras forums say that this will train over the entire dataset, but I can't intuitively understand why the network wouldn't relearn over just the last training chunk.</p>
<p>Some help understanding this would be much appreciated.</p>
<p>Best,
Joe</p> | 0 |
Mock for context-manager fails with AttributeError: __exit__ | <p>I am trying to patch some context manager function using a Mock so I can test that the code does sensible things given good, bad, and garbage input. Here is the test code with the <code>with</code> statement in it. The patch is done in the correct place in my code.</p>
<pre><code>@patch("__main__.opened_w_error")
def test_get_recipe_file(self, mo):
mo.return_value = (Mock(), None)
mo.__enter__ = Mock(return_value=None)
mo.__exit__ = Mock(return_value=None)
with mo(…) as (fd, err): # AttributeError: __exit__ is raised here.
print(fd)
print(err)
</code></pre>
<p>However the <code>with mo(…) as (fd, err)</code> raises <code>AttributeError: __exit__</code>.</p>
<p>The <a href="http://www.voidspace.org.uk/python/mock/magicmock.html?highlight=__exit__" rel="noreferrer">documentation for mocking magic methods</a> states the you should use it as</p>
<pre><code>with mo as (fd, err):
…
</code></pre>
<p>The latter piece of code is what I am trying to mock.
but that is not how I use it in my code. For those really interested, I am trying to mock <a href="https://www.python.org/dev/peps/pep-0343/" rel="noreferrer">example 6 <code>opened_w_error()</code> in PEP 343</a> which deals with opening files and catching errors. Thus the code is:</p>
<pre><code>with open_w_error(filename, 'r') as (fd, err):
…
</code></pre>
<p>The latter is what I am trying to mock.</p> | 0 |
DataTables Bootstrap pagination not rendering | <p>I have the sample DataTable working on my test server. However, for some reason the Bootstrap pagination is not rendering properly.</p>

<p><strong>Question</strong></p>
<p>So I would appreciate it if anyone could help me solve this issue.</p> | 0 |
manually add breaks to both x and y axis in ggplot2 | <p>I've typically changed the scale breaks for continuous variables in ggplot2 using <code>scale_y_continuous</code> (or <code>scale_x_continuous</code>). I also usually set the axis limits using <code>coord_cartesian(xlim=)</code> (or <code>ylim=</code> for y axis). All that works just fine like in the following:</p>
<pre><code>#Some example data
set.seed(100)
b<-sample(1:10, 10)
a<-sample(1:10, 10)
df<-data.frame(a,b)
#Graph without scales set (just default)
library(ggplot2)
ggplot(data=df, aes(a,b))+
theme_bw() + theme(panel.border = element_rect(colour = "black", fill=NA, size=1),
panel.grid.major = element_blank(),
panel.grid.minor = element_blank(),
axis.line = element_line(colour = "black"))+
geom_text(aes(label=rownames(df)), color="black")
</code></pre>
<p>That produces the following plot with default scales:</p>
<p><a href="https://i.stack.imgur.com/wldM5.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/wldM5.png" alt="enter image description here"></a></p>
<p>If I want to adjust the x-axis to, say, 1-13 (i.e. 13 tick marks starting at 1 and ending at 13) I would do the following:</p>
<pre><code>ggplot(data=df, aes(a,b))+
theme_bw() + theme(panel.border = element_rect(colour = "black", fill=NA, size=1),
panel.grid.major = element_blank(),
panel.grid.minor = element_blank(),
axis.line = element_line(colour = "black"))+
geom_text(aes(label=rownames(df)), color="black")+
scale_x_continuous(breaks = c(1,3,5,7,9,11,13))+
coord_cartesian(xlim=c(0, 13))
</code></pre>
<p><a href="https://i.stack.imgur.com/v4EYc.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/v4EYc.png" alt="enter image description here"></a></p>
<p>...and for the y-axis...</p>
<pre><code>ggplot(data=df, aes(a,b))+
theme_bw() + theme(panel.border = element_rect(colour = "black", fill=NA, size=1),
panel.grid.major = element_blank(),
panel.grid.minor = element_blank(),
axis.line = element_line(colour = "black"))+
geom_text(aes(label=rownames(df)), color="black")+
scale_y_continuous(breaks = c(1,3,5,7,9,11,13))+
coord_cartesian(ylim=c(0, 13))
</code></pre>
<p><a href="https://i.stack.imgur.com/aQa9T.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/aQa9T.png" alt="enter image description here"></a></p>
<p>However, when I try to accomplish the very same scale adjustment for both axes at the same time, the output does not produce what I would expect (which is 1-13 on both the x and y axes).</p>
<pre><code>ggplot(data=df, aes(a,b))+
theme_bw() + theme(panel.border = element_rect(colour = "black", fill=NA, size=1),
panel.grid.major = element_blank(),
panel.grid.minor = element_blank(),
axis.line = element_line(colour = "black"))+
geom_text(aes(label=rownames(df)), color="black")+
scale_y_continuous(breaks = c(1,3,5,7,9,11,13))+
coord_cartesian(ylim=c(0, 13))+
scale_x_continuous(breaks = c(1,3,5,7,9,11,13))+
coord_cartesian(xlim=c(0, 13))
</code></pre>
<p><a href="https://i.stack.imgur.com/xhEuA.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/xhEuA.png" alt="enter image description here"></a></p>
<p>As you can see, the x and y axis are not equivalent even though the exact same code has been passed to both axes. I don't understand why. Any help is much appreciated.</p> | 0 |

HackerRank says ~ no response on stdout ~ | <p>So I was solving this Question on HackerRank (Project Euler Q1) <a href="https://www.hackerrank.com/contests/projecteuler/challenges/euler001" rel="nofollow">link here</a>, and have used the following code to solve it</p>
<pre><code>import java.io.*;
import java.util.*;
import java.text.*;
import java.math.*;
import java.util.regex.*;
public class Solution {
public static void main(String[] args) {
/* Enter your code here. Read input from STDIN. Print output to STDOUT. Your class should be named Solution. */
int T = 0;
ArrayList<Integer> N = new ArrayList<Integer>();
String[] Input = args;
if (args.length>1){
T = Integer.parseInt(args[0]);
if(T<1||T>Math.pow(10,6))
System.exit(0);
}
if (args.length-1 == T){
for (int i=1;i<args.length;i++){
N.add(Integer.parseInt(args[i]));
int sum3=0,sum5=0,sum15=0;
int count=0;
while (count<N.get(i-1)){
sum3+=count;
count+=3;
}
count =0;
while (count<N.get(i-1)){
sum5+=count;
count+=5;
}
count =0;
while (count<N.get(i-1)){
sum15+=count;
count+=15;
}
N.set(i-1,(sum3+sum5-sum15));
}
}
for(int j=0;j<N.size();j++)
System.out.println(N.get(j));
}
}

<p>This gives me the following output on an IDE :</p>
<pre><code>23
2318
</code></pre>
<p>While Inputting : </p>
<pre><code>2
10
100
</code></pre>
<p>And this matches the expected output on HackerRank, but however When I use this code on the website, It says :</p>
<p>Input (stdin)</p>
<pre><code>2
10
100
</code></pre>
<p>Your Output (stdout)</p>
<pre><code>~ no response on stdout ~
</code></pre>
<p>Expected Output</p>
<pre><code>23
2318
</code></pre>
<p>Compiler Message</p>
<pre><code>Wrong Answer

<p>One thing I could observe was I couldn't print anything from inside a loop on HackerRank. What would the solution to this be?</p> | 0 |

Why my alert function is not working when I click on button in Vue.js | <p>This is my index.html</p>
<pre><code><body>
<app></app>

<p>This is my main.js</p>
<pre><code>import Vue from 'vue'
import App from './App'

<p>Here is the error message from the Chrome console:</p>

<p>I can see "Hello world!" on my screen and the button but nothing happened when I click on it.</p>
<p>I suppose I will have "test" alert message.</p>

SCSS color variables that belong to an object | <p>I am refactoring a project's SCSS to map colors to their own variable in a <code>_colors.scss</code> file.</p>
<p>More often than not, I am encountering the situation in which a selector has a <code>background-color</code> and <code>color</code>. So, I end up writing the following variables:</p>
<pre><code>$cool-table-bg: $brand-primary;
$cool-table-text: $white;
</code></pre>
<p>Pretty soon I end up with many, many versions of the above.</p>
<p>What I want to know is, can I assign the above to an object like you would do in JavaScript? For example:</p>
<pre><code>$cool-table: {
bg: $brand-primary;
text: $white;
}
</code></pre>
<p>I'd like to be able to refer to such colors as <code>$cool-table.bg</code>.</p>
<p>Is this possible?</p> | 0 |

How to use js modules from non-module files | <p>I'm a beginner at using js modules.</p>
<p>I'm working on a fairly simple web application. It uses typescript and angular 2, which heavily relies on modules.</p>
<p>Most of my app ts files 'import' one or many js modules (usually mostly angular 2 modules).</p>
<p>As I understand, because my app ts files have a top level 'import', they are automatically considered a js module by typescript.</p>
<p>However, I want any of my app ts files to be accessible by any other of my app ts files, without having to 'import' each other. But because they are now modules themselves, ts requires me to do that...</p>
<p>Is it possible?</p>
<p>It seems crazy to me that for each of my app ts file, I should have to declare every other of my app ts files that are used in there (I like to have tiny files with a single class/interface). In addition, this relies on relative paths which breaks as soon as I restructure my folder structure.</p>
<p>Am I thinking about this the wrong way?</p> | 0 |
how to remove standard background color of text in a div | <p><strong>EDIT: Solved it. I had to change from the tag html to body { background. Thank you for your help everyone</strong></p>
<p>I've searched on here and on google but I only get the opacity example, if I use opacity 0 then the text disappears too.</p>
<p>I have a html background meaning the complete page and in the code I've placed a div with a h1 and p tag with some text and then a white box-like background around the div of the text appears and I can't remove it.</p>
<pre><code><div class="container">
<div class="header-pris">
<h1>Pris alternativ:</h1>
<p>Skulle du vilja pröva enstaka timmar eller kanske tom mer timmar än vad som anges nedan så går det självklart också att annordna, kontakta oss direkt på
<a href="mailto:[email protected]"> [email protected]</a></p>
</div>
</div>
.header-pris {
text-align:center;
background-color:none;
}
</code></pre>
<p>tried with none as color but that doesn't do it so I don't know where I'm doing wrong or what the correct command should be to have no background on the div with the text so that you can see the image background</p> | 0 |

extract individual words from string c++ | <p>I am trying to make a C++ program that receives user input, and extracts the individual words in the string, e.g. "Hello to Bob" would get "Hello", "to", "Bob". Eventually, I will be pushing these into a string vector. This is the format I tried to use when designing the code:</p>
<pre><code>//string libraries and all other appropriate libraries have been included above here
string UserInput;
getline(cin,UserInput)
vector<string> words;
string temp=UserInput;
string pushBackVar;//this will eventually be used to pushback words into a vector
for (int i=0;i<UserInput.length();i++)
{
if(UserInput[i]==32)
{
pushBackVar=temp.erase(i,UserInput.length()-i);
//something like words.pushback(pushBackVar) will go here;
}
}
</code></pre>
<p>However, this only works for the first space encountered in the string.It does not work if there are any spaces before the word (e.g. if we have "Hello my World", pushBackVar will be "Hello" after the first loop, and then "Hello my" after the second loop, when I want "Hello" and "my".) How do I fix this? Is there any other better way to extract individual words from a string? I hope I haven't confused anyone. </p> | 0 |
ABAP hard code value into SELECT and field into another field | <p>It is possible in ABAP to make a select and include a hard code value and to put a value in any field.</p>
<p>In my exemple I have to fill a range with Company code BUKRS according to VKORG so I have to do a select on TVKO like that:</p>
<pre><code>DATA : lt_rtvko TYPE RANGE OF bukrs.
SELECT 'I' as sign 'EQ' as option bukrs as low
INTO CORRESPONDING FIELDS OF TABLE lt_rtvko
FROM tvko
WHERE vkorg EQ p_vkorg.
</code></pre>
<p>But I have a dump.</p>
<p>I know a longer solution to do this, To fill manually a table of TVKO and make a LOOP to fill the range, BUT I am sure that we have a solution to do that in one operation like in my example.</p>
<p>Thanks, Experts.</p> | 0 |

Python - SQLite JSON1 load extension | <p>I want to use the json1 extension for SQLite within Python. According to the <a href="http://sqlite.org/json1.html" rel="noreferrer">official documentation</a>, it should be a loadable extension. I got the json1.c file from the <a href="http://sqlite.org/cgi/src/raw/ext/misc/json1.c?name=9799e4252b305edcbe659329eec3ca80ed85f968" rel="noreferrer">source</a> and compiled it into json1.so as per the <a href="http://sqlite.org/loadext.html#build" rel="noreferrer">official instructions</a> without any errors.</p>
<pre><code>$ gcc -g -fPIC -shared json1.c -o json1.so
</code></pre>
<p>The trouble came up when I tried to load the extension in Python 2.7.12 (and 3.5.2) according to the <a href="http://docs.python.org/2/library/sqlite3.html" rel="noreferrer">sqlite3 documentation</a>.</p>
<pre><code>>>> import sqlite3
>>> con = sqlite3.connect(":memory:")
>>> con.enable_load_extension(True)
>>> con.load_extension("./json1.so")
</code></pre>
<p>I received the following traceback error message. I ran the Python interpreter from the folder with the json1.so file in it. Even though it seems like there should be more information due to the last colon, the following is the complete error message.</p>
<pre><code>Traceback (most recent call last):
File "<stdin>", line 1, in <module>
sqlite3.OperationalError: error during initialization:
</code></pre>
<p>Is it actually not possible to use json1 as a loadable extension within Python? Is my only option to recompile SQLite, pysqlite2, etc. as explained in <a href="http://charlesleifer.com/blog/using-the-sqlite-json1-and-fts5-extensions-with-python/" rel="noreferrer">this</a> blog post by Charles Leifer?</p>
<p>EDIT:</p>
<p>As it turns out, I was receiving the error because my machine already had this and other extensions already enabled. The action of enabling an already enabled extension triggered the error. So far, all linux computers I have access to already have the json1 and fts5 extensions enabled in the SQLite that comes with Python. You can check which compile options have been used by connecting to a SQLite database and running the following query.</p>
<pre><code>PRAGMA compile_options;

Custom Cell Reorder Behavior in CollectionView | <p>I am able to reorder my collectionView like so:</p>
<p><a href="https://i.stack.imgur.com/BbqAL.gif" rel="noreferrer"><img src="https://i.stack.imgur.com/BbqAL.gif" alt="enter image description here"></a></p>
<p>However, instead of all cells shifting horizontally, I would just like to swap with the following behavior (i.e. with less shuffling of cells):</p>
<p><a href="https://i.stack.imgur.com/HLhAO.gif" rel="noreferrer"><img src="https://i.stack.imgur.com/HLhAO.gif" alt="enter image description here"></a></p>
<p>I have been playing with the following delegate method:</p>
<pre><code>func collectionView(_ collectionView: UICollectionView, targetIndexPathForMoveFromItemAt originalIndexPath: IndexPath, toProposedIndexPath proposedIndexPath: IndexPath) -> IndexPath
</code></pre>
<p>however, I am unsure how I can achieve custom reordering behavior. </p> | 0 |
Redux: Create root reducer from combineReducers and "loose" properties | <p>I want to create a Redux store that has this shape:</p>
<pre><code>store = {
loaded: Boolean,
loading: Boolean,
view: Object, // uses combineReducers
layers: Object // uses combineReducers
}
</code></pre>
<p>So far, my root reducer looks like this:</p>
<p><strong>rootReducer.js</strong></p>
<pre><code>import view from './view';
import layers from './layers';
const initialState = {
loaded: false,
loading: false,
};
function loadState(state = initialState, action = {}) {
switch (action.type) {
case 'LOADED':
return {
...state,
loaded: true,
loading: false,
};
case 'LOADING':
return {
...state,
loaded: false,
loading: true,
};
default:
return state;
}
}
export default combineReducers({
view,
layers,
// hmmmm, putting loadState here would give me a loadState object property,
// not loose 'loaded' and 'loading' properties
});
</code></pre>
<p>How do I also have these "loose" properties like <code>loaded</code> and <code>loading</code> alongside them?</p> | 0 |

re-enable disabled menu "save video as" chrome ext or chrome itself "Save Video As" | <p>How can I re-enable the "Save Video As" option when it is disabled on a video?</p>

Setup One to Many without Foreign Key Entity Framework | <p>I have the following design.
<a href="https://i.stack.imgur.com/bghEf.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/bghEf.png" alt="enter image description here"></a>
As we can see from this image, an Episode will have multiple EpisodePatients, and each of these EpisodePatients, will point to one Episode.</p>
<p>Here are my two models corresponding to the tables.</p>
<pre><code>public class EpisodeModel
{
public int ID { get; set; }
public virtual EpisodePatientModel EpisodePatient { get; set; }
}
public class EpisodePatientModel
{
public int EpisodePatientID { get; set; }
public virtual EpisodeModel Episode { get; set; }
}
</code></pre>
<p>How do I setup the One to Many relationship between <code>EpisodeModel</code> and <code>EpisodePatientModel</code>?</p>
<p>Since <code>EpisodeModel</code> does not contain a foreign key to EpisodePatient, I cannot do the following.</p>
<pre><code>modelBuilder.Entity<EpisodeModel>().HasRequired(r => r.EpisodePatient).WithMany().HasForeignKey() //No foreign key
</code></pre>
<p>I have tried this.</p>
<pre><code>modelBuilder.Entity<EpisodeModel>().HasRequired(r => r.EpisodePatient);
</code></pre>
<p>But with this approach, the EpisodeModel is not Lazy loaded when loading all EpisodePatientModels form the DB</p> | 0 |
