Karate is not loading spring boot class with Autowired annotation

<p>I have a requirement to automate apache kafka test where my development team is using @Autowired annotaion to load the beans.</p>
<pre><code>@Component

How to POST a form with Django and not reload the page

<p>I'm working on an app where the user will submit a value and I want to hide the div containing the form on submit and display a div containing the results.

<p>I tried changing the JavaScript to a bunch of different things, but the only thing that it does it reload the page. I want to get rid of the reload and stay on the same page but still post the data and hide/show the divs.</p>

Text does not show string in CountDownTimer
|
<p>I have a CountDownTimer Class to set a countdown which will start will when the user clicks some Button.<br>
This is the code that includes the CountDownTimer </p>
<pre><code> public class play extends Activity implements View.OnClickListener{
private TapCountDownTimer countDownTimer;
private final long startTime = 10;
private final long interval = 1;
private TextView countdowntext;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.play);
countDownTimer = new TapCountDownTimer(startTime, interval);
countdowntext = (TextView)findViewById(R.id.countdowntext);
countdowntext.setText(String.valueOf(startTime));
Button buttonstart = (Button)findViewById(R.id.stopbutton);
buttonstart.setOnClickListener(new View.OnClickListener() {
public void onClick(View v){
countDownTimer.start();
}
});
Button buttonstop = (Button)findViewById(R.id.stopbutton);
buttonstop.setOnClickListener(new View.OnClickListener() {
public void onClick(View v){
countDownTimer.cancel();
}
});
public class TapCountDownTimer extends CountDownTimer {
public TapCountDownTimer(long startTime, long interval)
{
super(startTime, interval);
}
@Override
public void onTick(long millisUntilFinished)
{
countdowntext.setText(Long.toString(millisUntilFinished/1));
}
@Override
public void onFinish()
{
countdowntext.setText("Time's up!");
}
}
}
</code></pre>
<p>I set the text in this line </p>
<pre><code>countdowntext.setText(Long.toString(millisUntilFinished/1));
</code></pre>
<p>But it's not working and the text shows "Time's Up" instead of the countdown.<br>
Does anyone know how to fix this issue?</p>

Read HTTP POST from mobile in java
|
<p>I have iOS Swift code, which sends a POST request to server. If i send this code directly to apple server i get response back with proper data. But when i send this to my server, server could not get the body of the HTTP POST. </p>
<p>I have no idea whether this issue is related to client side or server side.</p>
<p>Here is the Swift code.</p>
<pre><code>func validateReceipt(completion : (status : Bool) -> ()) {
let receiptUrl = NSBundle.mainBundle().appStoreReceiptURL!
if NSFileManager.defaultManager().fileExistsAtPath(receiptUrl.path!)
{
if let receipt : NSData = NSData(contentsOfURL: receiptUrl)
{
let receiptdata: NSString = receipt.base64EncodedStringWithOptions(NSDataBase64EncodingOptions.EncodingEndLineWithLineFeed)
let dict = ["receipt-data" : receiptdata]
let jsonData = try! NSJSONSerialization.dataWithJSONObject(dict, options: NSJSONWritingOptions(rawValue: 0))
let request = NSMutableURLRequest(URL: NSURL(string: ReceiptURL.MAIN_SERVER.rawValue)!)
let session = NSURLSession.sharedSession()
request.HTTPMethod = "POST"
request.HTTPBody = jsonData
let task = session.dataTaskWithRequest(request, completionHandler: { data, response, error in
if let dataR = data
{
self.handleData(dataR, completion: { status in
completion(status: status)
})
}
})
task.resume()
}
else
{
completion(status: false)
}
}
else
{
completion(status: false)
}
}
</code></pre>
<p>and here is my Java code in server side, there are two Java classes which take care of this</p>
<pre><code>MyRequestWrapper.Java
package webservice;
import java.io.BufferedReader;
import java.io.ByteArrayInputStream;

if (inputStream != null) {
bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
char[] charBuffer = new char[100000];
int bytesRead = -1;
while ((bytesRead = bufferedReader.read(charBuffer)) > 0) {
stringBuilder.append(charBuffer, 0, bytesRead);
}
} else {
stringBuilder.append("");
}
} catch (IOException ex) {
throw ex;
} finally {
if (bufferedReader != null) {
try {
bufferedReader.close();
} catch (IOException ex) {

}
@Override
public BufferedReader getReader() throws IOException {
return new BufferedReader(new InputStreamReader(this.getInputStream()));
}
public String getBody() {
return this.body;
}
}
</code></pre>
<p>And here is the another class.</p>
<pre><code>GetResult.Java

</code></pre>
<p>We could get the client IP and client Port from this request but unable to get the body. In production also we could not get the body. Some Java developers told me that you cant directly get the raw bytes in Java, i don't know about this.</p>
<p>Somebody please take a look at this, and tell me what i am doing wrong.</p>

error: cannot allocate an object of abstract type
|
<p>As much as I want to create an MVCE of this problem...I really can't. I am using an open source fluid flow solver called Palabos with its dev guide also available . It is based on generic structures and mpi. Probably the best available open source solver of its kind</p>
<p>The developers there use Box Processors for cycling through arrays(generally speaking..it can be tensors, lattice are other objects). Here is a way they use processors for a single lattice case</p>
<pre><code>struct IniTemperatureRayleighBenardProcessor2D :
public BoxProcessingFunctional2D_L<T,adDescriptor>
{
IniTemperatureRayleighBenardProcessor2D(RayleighBenardFlowParam<T,nsDescriptor,adDescriptor> parameters_)

{ }
virtual void process(Box2D domain, BlockLattice2D<T,adDescriptor>& adLattice)
{
Dot2D absoluteOffset = adLattice.getLocation();
Array<T,adDescriptor<T>::d> jEq(0.0, 0.0);
for (plint iX=domain.x0; iX<=domain.x1; ++iX) {
for (plint iY=domain.y0; iY<=domain.y1; ++iY) {
//some operations...............
}
}
}
virtual IniTemperatureRayleighBenardProcessor2D<T,nsDescriptor,adDescriptor>* clone() const

}

}
virtual BlockDomain::DomainT appliesTo() const {
return BlockDomain::bulkAndEnvelope;
}
private :
RayleighBenardFlowParam<T,nsDescriptor,adDescriptor> parameters;
};
</code></pre>
<p>Here how they call it</p>
<pre><code> applyProcessingFunctional (
new IniTemperatureRayleighBenardProcessor2D<T,NSDESCRIPTOR,ADESCRIPTOR>(parameters), adLattice.getBoundingBox(),
adLattice );
</code></pre>
<p>Details of the whole procedure are at (<a href="http://www.palabos.org/documentation/userguide/data-processors.html" rel="nofollow">http://www.palabos.org/documentation/userguide/data-processors.html</a>)</p>

<p>Now, here is my problem.
I am using a similar data processor to perform operation on two scalar arrays. Tried to understand as much as of the source code as possible</p>
<pre><code>template<typename T1, typename T2>
//template<typename T, template<typename NSU> class nsDescriptor,
// template<typename ADU> class adDescriptor, typename T1, typename T2>

}
}
}

}
virtual BlockDomain::DomainT appliesTo() const {
return BlockDomain::bulkAndEnvelope;
}
private :
RayleighBenardFlowParam<T,NSDESCRIPTOR,ADESCRIPTOR> parameters;
};
</code></pre>
<p>and here is how I call it</p>
<pre><code>applyProcessingFunctional (
new IniFluxMultiplier2D<T,T>(parameters), boolMask.getBoundingBox(), boolMask,FluxMultiplier);
</code></pre>
<p>I am getting the error</p>
<pre><code>error: cannot allocate an object of abstract type ‘IniFluxMultiplier2D<double, double>’|
</code></pre>
<p>Tried debugging it but I am stuck and really can't figure a way out. I don't really expect anyone to run this, but I know I am making a conceptual mistake at the starting of the structure which I can't really figure out.</p>
<p>T is decalared as </p>

Apache Tiles 3 with Freemarker basic setup, not working
|
<p>I have not been able to get a very simple freemarker template working with Tiles 3. The examples on the site seem to be for version 2.x as the programmatic configuration references classes that don't exist in tiles 3.</p>
<p>With the following cofiguration, my template displays as is (that is it does not include any tiles). How can I fix this?</p>
<p><strong>When rendering page:</strong>
When using the url: <code>http://localhost:8080/TilesFreeMarker/myapp.homepage.tiles</code> I get exactly the same content as it in the templage.ftl file below. If I replace all ftl files with jsp's (and the required tags) the example then behaves as expected, but I require freemarker functionality.</p>

Improper behavior of Host Alias
|
<p>I have two host alias in my directory structure that fail to properly register with g-wan. My folder structure is as follows:</p>
<blockquote>
<p>/srv/gwan_linux64-bit/192.168.3.101_80/$dg.lcl <br>
/srv/gwan_linux64-bit/192.168.3.101_80/$myapp <br>
/srv/gwan_linux64-bit/192.168.3.101_80/#192.168.3.101 <br>
/srv/gwan_linux64-bit/192.168.3.101_80/#192.168.3.101:gwan.klickitat.lcl
<br> /srv/gwan_linux64-bit/192.168.3.101_80/#192.168.3.101:test.lcl
<br></p>
</blockquote>
<p>When starting g-wan, I receive the error:</p>
<blockquote>
<p>loading.........
* unresolved aliases: 2
<br></p>
</blockquote>
<p><br>
From the sample server report in the default g-wan configuration:</p>
<blockquote>
<p>Listeners <br> 5 host(s): 192.168.3.101_80 <br> Virtual: $dg.lcl <br>
Root: #test.lcl <br> Root: #gwan.klickitat.lcl <br> Virtual: $myapp
<br> Root: #192.168.3.101 <br></p>
</blockquote>
<p>As you can see, g-wan identifies the two root aliases as additional roots. G-wan only allows a single root host, so the two alias fail to function in the browser with a 404 error. Each of the hosts respond properly to ping, so they are accounted for by the dns. The virtual hosts and root host function as expected.</p>
<p>Thoughts?</p>
<hr>
<h2>Additional research:</h2>
<p>I have corrected my posting error and simplified the presentation. I hope that you will find this to be concise.</p>
<p>My hosts file is as follows for all tests: <br></p>
<blockquote>
<p>127.0.0.1 localhost.klickitat.lcl localhost <br>
192.168.3.101 gwan.klickitat.lcl test.lcl <br></p>
</blockquote>
<p>I implemented an example that is identical to your test with the exception that I used a different IP address to match my local subnet and I eliminated the virtual hosts, which do not impact my result in my testing. <br><br>
The only changes to the default gwan configuration are as follows: <br></p>
<ul>
<li>Changed the listener from 0.0.0.0_8080 to 192.168.3.101_8080</li>
<li>Changed the root host IP from #0.0.0.0 to #192.168.3.101</li>
<li>Added two host aliases #192.168.3.101:gwan.klickitat.lcl and
#192.168.3.101:test.lcl</li>
</ul>
<p>This is my folder structure: <br></p>
<blockquote>
<p>/srv/gwan_linux64-bit/192.168.3.101_8080 <br>
/srv/gwan_linux64-bit/192.168.3.101_8080/#192.168.3.101 <br>
/srv/gwan_linux64-bit/192.168.3.101_8080/#192.168.3.101:gwan.klickitat.lcl
<br> /srv/gwan_linux64-bit/192.168.3.101_8080/#192.168.3.101:test.lcl
<br></p>
</blockquote>
<p>This is my result as reported by gwans included server report application: <br></p>
<blockquote>
<p>3 host(s): 192.168.3.101_8080 <br> Root: #test.lcl <br> Root:
#gwan.klickitat.lcl <br> Root: #192.168.3.101 <br></p>
</blockquote>
<p>Gwan does not recognize the aliases and I cannot access the aliased urls. My result is inconsistent with yours. <br> </p>
<p>The rest of this post is intended only to illustrate that aliases are reported by gwan in alternate configurations in my environment, but with some inconsistencies in the expected outcome. I simply identify the folder structure and my result.</p>
<p><strong>Alternate Config 1</strong> <br>
/srv/gwan_linux64-bit/0.0.0.0_8080 <br>
/srv/gwan_linux64-bit/0.0.0.0_8080/#localhost <br>
/srv/gwan_linux64-bit/0.0.0.0_8080/#localhost:gwan.klickitat.lcl <br>
/srv/gwan_linux64-bit/0.0.0.0_8080/#localhost:test.lcl <br></p>
<p><strong>Result:</strong> <br>
3 host(s): 0.0.0.0_8080 <br>
Root: #localhost <br>
Alias: 0.0.0.0:#gwan.klickitat.lcl <br>
Alias: 0.0.0.0:#test.lcl <br></p>
<p><strong>Alternate Config 2</strong> <br>
/srv/gwan_linux64-bit/192.168.3.101_8080 <br>
/srv/gwan_linux64-bit/192.168.3.101_8080/#localhost <br>
/srv/gwan_linux64-bit/192.168.3.101_8080/#localhost:gwan.klickitat.lcl <br>
/srv/gwan_linux64-bit/192.168.3.101_8080/#localhost:test.lcl <br></p>
<p><strong>Result:</strong> <br>
3 host(s): 192.168.3.101_8080 <br>
Root: #localhost <br>
Alias: 192.168.3.101:#gwan.klickitat.lcl <br>
Alias: 192.168.3.101:#test.lcl <br></p>
<p>While the alternate configurations function, note that the aliases naming varies from the explicit naming in the folder structure. It appears that the listeners are being properly set up, but that there is some issue in how the host laiases are being generated. I'm happy to test further if you so desire.</p>

SPAlbumBrowse - Getting an Accurate List Of An Artist's Albums
|
<p>Okay. This is getting crazy. I've been working on this for a few days trying different weird things. I think I had a nightmare last night about libSpotify, might be a product of my sleeping habits, but, I digress.</p>
<p>Anyway. Let's look up the artist "The XX" with the following code. Assume that <em>artist</em> is initialized with the artist "the xx", Spotify url spotify:artist:3iOvXCl6edW5Um0fXEBRXy</p>
<pre><code>artistBrowse = [[SPArtistBrowse alloc] initWithArtist: artist inSession: spotifySession type: SP_ARTISTBROWSE_ALBUMS];
[SPAsyncLoading waitUntilLoaded: artistBrowse timeout: kSPAsyncLoadingDefaultTimeout then:^(NSArray *loadedItems, NSArray *notLoadedItems) {
[SPAsyncLoading waitUntilLoaded: artistBrowse.albums timeout: kSPAsyncLoadingDefaultTimeout then:^(NSArray *loadedItems, NSArray *notLoadedItems) {
NSArray *types = @[@"a", @"s", @"c", @"u"];
for(SPAlbum *album in loadedItems) {
NSLog(@"%@, %@, %@, %d, %-50s, %@", types[album.type], album.available ? @"Y" : @" N", album.artist.name, album.year, album.name.UTF8String, album.spotifyURL);
}
}];
}];
</code></pre>
<p>Here's the output. Sorry, it's kind of lengthy. Note that the first column refers to the SP_ALBUM_TYPE of the album (a = album, s = single, c = compilation, u = unknown), the second column is a Y or N depending on if the album is available in my session's region (US), the third column is the artist name, the fifth is the album's year, the sixth is the album's name, and lastly the Spotify URL of the album.</p>

<p>Out of this data, I want to extract something like the following. These are the xx's albums on their artist page the official Spotify desktop client with the same account I'm using to log into libSpotify with.</p>
<p><img src="https://i.stack.imgur.com/7frlX.png" alt=""></p>
<p>Note that in the output, even after I've loaded all of the albums from artistBrowse.albums, the two items that are actual albums available in my region are <em>all</em> listed as unavailable, and only one is actual listed as an album. </p>

<p>How do I solve this problem? Lots of times, if you go and check the web-api with the Spotify URLs of albums that say they're not available in my region through album.available, the "US" region code is right in the output from the album's result page from the web-api. Secondly, I get WIDELY different results all of the time. Nothing's consistent, sometimes Red Hot Chili Peppers' album "I'm With You" shows up as available in my region, sometimes there isn't one that is available in my region. If there are albums that are not available in my region, sometimes calling another <em>waitUntiLoaded:</em> call with the <em>loadedItems</em> returned in the <em>waitUntilLoaded</em> call with artistBrowse.albums solves the issue; loading the "loaded items" again alleviates the issue occasionally? That doesn't even make sense.</p>
<p>Lastly, wtf.</p>

<p><strong>HELP</strong> please, this is a huge bummer. I am literally at a total loss here on how to go about getting <em>any</em> sort of reliable list, though I'm convinced that if the official client can do it, then I can too. I've been staring at this for so many days I'm thinking about backing up my search with a call to the web-api and like, using the web-api to give me album lists for artists.... sounds really unpleasant though. Otherwise, the library has been quite a joy to work with. Thanks again for your help!</p>

Is there a different way to put 3 plots together into 1 image besides using ggpubr in R?
|
<p>I have been using the code below to create 3 separate plots and then using ggarrange in the ggpubr package to combine them into one plot and saving it as an image. However, once I created an Rmd of my script this function is very temperamental and gives me the error "Faceting variables must have at least one value" even when it runs fine outside of the Rmd. Is there a different way to get the same results using something in the ggplot2 package? or another simpler way?
Edit: I would like to maintain the girds in my graph and not use a complex way to get a common legend that cowplot requires.</p>

Android - OpenGL Image doesnt rotate (almost completed)

<p>I was following a OpenGL tutorial (<a href="https://developer.android.com/training/graphics/opengl/touch.html#angle" rel="nofollow noreferrer">https://developer.android.com/training/graphics/opengl/touch.html#angle</a>) and I did everything right I think. <strong>My problem is that the triangle doesnt rotate on the display.</strong> I tried to debug and <code>mGLView.requestRender();</code> is getting the values but it doesnt update the image on the screen.</p>

How to get the selected texts and display them?

<p>What I'm trying to do is to grab the selected option from each of the selection boxes, click 'submit' and store them in the "stored" paragraph.</p>
<p>Here is my HTML:</p>
<pre><code><body>
<div id="container">

</code></pre>
<p>Javascript:</p>
<pre><code>var numbers = [ '1', '2', '3', '4', '5', '6' ];
var dices = [ 'dice1', 'dice2', 'dice3', 'dice4', 'dice5', 'dice6' ];
var select = [ 'select1', 'select2', 'select3', 'select4', 'select5', 'select6']
function rolldices() {
for (var diceindex=0; diceindex<dices.length; diceindex++) {
var dice_value = Math.floor((Math.random()*numbers.length));
document.getElementById("dice" + (diceindex + 1)).innerHTML=numbers[dice_value];
}
} // end of rolldices()
</code></pre>
<p>Here is my attempt at solving the problem:</p>
<pre><code>function submit() {
for (var selectindex=0; selectindex<select.length; selectindex++) {
var e = document.getElementById("select" + (selectindex + 1));
var storedNumbers = e.options[e.selectedIndex].text;
document.getElementById("select" + (selectindex + 1)).text;
document.getElementById("stored").innerHTML=storedNumbers;
}
} // end of submit()
</code></pre>
<p>This works SORT OF, but only the last selectbox's text is being displayed in the "stored" paragraph.. What is wrong?</p>

Bind the error data of datagridrow to a tooltip textblock
|
<p>I am trying to show the validation error message of data grid row in a tooltip. Here is the code that works when I use the ToolTip property of the Grid control directly (wihtout styling):</p>
<pre><code><Grid Margin="0,-2,0,-2" ToolTip="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type DataGridRow}}, Path=(Validation.Errors)[0].ErrorContent}">
<Ellipse StrokeThickness="0" Fill="Red"
Width="{TemplateBinding FontSize}"
Height="{TemplateBinding FontSize}" />
<TextBlock Text="!" FontSize="{TemplateBinding FontSize}"
FontWeight="Bold" Foreground="White"
HorizontalAlignment="Center" />
</Grid>
</code></pre>
<p>Now this shows the tooltip correctly. Everything is fine.</p>
<p><strong>Problem:</strong></p>
<p>As soon as I start styling the ToolTip separately, the binding stops working somehow. Here is the code that I am trying which does not work:</p>
<pre><code><Grid Margin="0,-2,0,-2">
<Ellipse x:Name="ErrorEllipse" StrokeThickness="0" Fill="Red"
Width="{TemplateBinding FontSize}"
Height="{TemplateBinding FontSize}" />
<TextBlock Text="!" FontSize="{TemplateBinding FontSize}"
FontWeight="Bold" Foreground="White"
HorizontalAlignment="Center"/>
<Grid.ToolTip>
<ToolTip Background="Transparent" BorderBrush="Transparent" Height="Auto" Width="Auto">
<Border >
<TextBlock Text= "{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type DataGridRow}}, Path=(Validation.Errors)[0].ErrorContent}"
MinHeight="20"
MinWidth="100"
Foreground="White"
Background="Red"/>
</Border>
</ToolTip>
</Grid.ToolTip>
</Grid>
</code></pre>
<p>What am I missing here and how can I achieve the proper binding? Probably its something basic but I have no idea...</p>

React native create custom modal using render props
|
<p>I want to create a Modal component and I want to have possibility to inject to it everything what I want. Firstly I decided to use HOC but then I've changed my solution to render props. Everything works fine but I don't really like this solution. I'm wondering how could I optimize it to make it better. What is the best practise to create such kind of modal where you have button opening this modal beyond modal component. I really don't like that now I have two components with open/close state of modal. And both of them have a toggle method to open/close modal. Any suggestion? Maybe I should stick with the HOC ? </p>
<p>Here's the code with Component.js where CustomModal is used:</p>
<pre><code>toggleModalVisibility = (visible) => {
this.setState({modalVisible: visible});
};
render() {
const question = this.props.questions[this.props.counter];
return (
<View style={styles.questionContainer}>
<CustomModal
visible={this.state.modalVisible}
toggleModalVisibility={this.toggleModalVisibility}
render={() => (
<>
<Text>{question.text}</Text>
<Text>{question.details}</Text>
</>
)}
/>
<View style={styles.questionTextContainer}>
<Text style={styles.questionText}>{question.text}</Text>
<TouchableOpacity onPress={() => this.toggleModalVisibility(!this.state.modalVisible) }>
<FontAwesome5 name='question-circle' size={30} color='#B7DBF3' light />
</TouchableOpacity>
</View>
</View>
)
}
</code></pre>
<p>and here's the code of CustomModal.js</p>
<pre><code>export default class CustomModal extends Component {
constructor(props) {
super(props);
this.state = {
isOpen: this.props.visible
};
}
componentDidUpdate(prevProps) {
if (prevProps.visible !== this.props.visible) {
this.setState({isOpen: this.props.visible});
}
}
toggle = (isOpen) => {
this.setState({ isOpen });
this.props.toggleModalVisibility(isOpen)
}
render() {
return (
<View>
<Modal
animationType='slide'
transparent={false}
visible={this.state.isOpen}
>
<View style={{marginTop: 30, marginLeft: 5}}>
<TouchableHighlight
onPress={() => {
this.toggle(!this.state.isOpen)
}}>
<FontAwesome5 name='times-circle' size={30} light />
</TouchableHighlight>
<View>{this.props.render()}</View>
</View>
</Modal>

string adminPassword = ADScriptService.Properties.Settings.Default.ServerAdminPwd;
string userName = "exampleUser";
string newPassword = "P455w0rd";
try
{
search.Filter = String.Format("sAMAccountName={0}", userName);
search.SearchScope = SearchScope.Subtree;
search.CacheResults = false;
SearchResult searchResult = search.FindOne();
if (searchResult == null) Console.WriteLine("User Not Found In This Domain");
DirectoryEntry userEntry = searchResult.GetDirectoryEntry();
userEntry.Path = userEntry.Path.Replace(":389", "");
Console.WriteLine(String.Format("sAMAccountName={0}, User={1}, path={2}", userEntry.Properties["sAMAccountName"].Value, userEntry.Username, userEntry.Path));
userEntry.Invoke("SetPassword", new object[] { newPassword });
userEntry.Properties["userAccountControl"].Value = 0x0200 | 0x10000;
userEntry.CommitChanges();
Console.WriteLine("Se ha cambiado la contraseña");
}
catch (Exception ex)
{
Console.WriteLine(ex);
}
}
}
}
</code></pre>
<p>This is an example with a single user, but what my program should do is iterate through ~120k users.
However, the operation of setting the search filter, finding one result and getting the DirectoryEntry takes about 2 or 3 seconds per user so I'm trying to use the DirectoryEntries structure given by the DirectoryEntry.Children property, which means replacing the six lines after "try{" with simply <code>DirectoryEntry userentry = directoryEntry.Children.Find("CN=" + userName);</code></p>
<p>So the example's code would look like this:</p>
<pre><code>using System;
using System.Collections;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.DirectoryServices;
namespace ADScriptService.core
{
class ExportTool
{
const AuthenticationTypes = AuthenticationTypes.Secure | AuthenticationTypes.Sealing | AuthenticationTypes.ServerBind;
private static DirectoryEntry directoryEntry = new DirectoryEntry(ADScriptService.Properties.Settings.Default.ActiveDirectoryPath, ADScriptService.Properties.Settings.Default.ServerAdminUser, ADScriptService.Properties.Settings.Default.ServerAdminPwd, AuthenticationTypes.Secure);
private static DirectorySearcher search = new DirectorySearcher(directoryEntry);
public void Export()
{
string path = ADScriptService.Properties.Settings.Default.ActiveDirectoryPath;
string adminUser = ADScriptService.Properties.Settings.Default.ServerAdminUser;
string adminPassword = ADScriptService.Properties.Settings.Default.ServerAdminPwd;
string userName = "exampleUser";
string newPassword = "P455w0rd";
try
{
DirectoryEntry userEntry = directoryEntry.Children.Find("CN=" + userName);
userEntry.Path = userEntry.Path.Replace(":389", "");
Console.WriteLine(String.Format("sAMAccountName={0}, User={1}, path={2}", userEntry.Properties["sAMAccountName"].Value, userEntry.Username, userEntry.Path));
userEntry.Invoke("SetPassword", new object[] { newPassword });
userEntry.Properties["userAccountControl"].Value = 0x0200 | 0x10000;
userEntry.CommitChanges();
Console.WriteLine("Se ha cambiado la contraseña");
}
catch (Exception ex)
{
Console.WriteLine(ex);
}
}
}
}
</code></pre>
<p>But this code gets the following error in the invocation line <code>(userEntry.Invoke("SetPassword", new object[] { newPassword });</code>:</p>
<pre><code>System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Runtime.InteropServices.COMException: The RPC server is unavailable. (Excepción de HRESULT: 0x800706BA)
</code></pre>
<p>which in english means RCP server unavailable. I've been stuck here for some days, and I've only found that it can be because of some authentication problem.
Invoking the method "Groups" works (<code>userEntry.Invoke("Groups");</code>) and the administrator, which is the user I'm loging in with to the ActiveDirectory has all the privileges. Also the password policy is completly permissive with no minimum lenght or complexity.</p>
<p>Again, because the program must iterate through, the real program actually iterates through the DirectoryEntry's children with:</p>
<pre><code>foreach(DirectoryEntry child in directoryEntry.Children)
{
child.Invoke("SetPassword", new object[] { newPassword });
child.CommitChanges();
}
</code></pre>
<p>Thank you very much!</p>

Substituting text inside buttons with widgets
|
<p>My app (using kivy) needs to substitute text with widgets inside an unspecified number of buttons using iteration. I don't use kv language. Only the last button displays any content.</p>
<p>My app should display an unspecified number of buttons. Simplified example:</p>
<pre><code>import kivy
kivy.require('2.0.0')
from kivy.app import App
from kivy.core.window import Window
from kivy.uix.widget import Widget
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.anchorlayout import AnchorLayout
from kivy.uix.gridlayout import GridLayout
from kivy.uix.button import Button
from kivy.uix.label import Label
from kivy.uix.image import Image
class Layout(Widget):
def __init__(self, app):
super().__init__()
self.layout = BoxLayout(orientation='vertical', size=Window.size)
contents = ['text1', 'text2', 'text3']
for text in contents:
button = Button(height=300, size_hint=(1, None))
button.text = text
self.layout.add_widget(button)
self.add_widget(self.layout)
class MyApp(App):
def build(self):
self.form = Layout(self)
return self.form
def on_pause(self):
return True
if __name__ in ('__main__', '__android__'):
MyApp().run()
</code></pre>
<p>Only instead of text buttons display images with descriptions. I change the code:</p>
<pre><code>import kivy
kivy.require('2.0.0')
from kivy.app import App
from kivy.core.window import Window
from kivy.uix.widget import Widget
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.anchorlayout import AnchorLayout
from kivy.uix.gridlayout import GridLayout
from kivy.uix.button import Button
from kivy.uix.label import Label
from kivy.uix.image import Image
class Layout(Widget):
def __init__(self, app):
super().__init__()
self.layout = BoxLayout(orientation='vertical', size=Window.size)
contents = [('img1', 'text1'), ('img2', 'text2'), ('img3', 'text3')]
for img, text in contents:
button = Button(height=300, size_hint=(1, None))
button_layout = BoxLayout(orientation='vertical', size_hint=(1, 1))
label = Label(text=text)
image = Image(source=f'{img}.jpg', size_hint=(1, 1), allow_stretch=True)
button_layout.add_widget(image)
button_layout.add_widget(label)
button.add_widget(button_layout)
self.layout.add_widget(button)
self.add_widget(self.layout)
class MyApp(App):
def build(self):
self.form = Layout(self)
return self.form
def on_pause(self):
return True
if __name__ in ('__main__', '__android__'):
MyApp().run()
</code></pre>
<p>And only the last button displays content.</p>
<p>As far as I can understand, at some point Python automatically gets read of the content of the previous button. How can I prevent it? Also what is the best way to center it?
I'm not a native speaker, so sorry for bad grammar. Thank you in advance.</p>

Vue - Component abstraction and inheritance
|
<p>I have a Vue application that allows users to create quizzes made up of different types of questions. I have multiple choice questions (both single selection/radio button and multiple selection/checkbox), open answer, attachment answer, so on and so forth.</p>
<p>I'm looking to create a generic <code>Question</code> component that will display the correct type of input (text editor, radio buttons, file input, etc.) depending on the type of question.</p>
<p>Let's assume I am using TS and I have a <code>Question</code> interface with a field <code>questionType</code> that easily allows differentiating among the types of questions.</p>
<p>The solution I've come up with is the following:</p>
<p>I have an <code>AbstractQuestion</code> component that defines the general template of the questions, i.e. there's a slot for displaying the question text and one for the inputs.</p>
<p>Then, for each type of question, there's a component, e.g. <code>OpenAnswerQuestion</code>, in whose template there is an <code>AbstractQuestion</code> with the slots filled with the correct template parts. Finally, I expose to the rest of the app a <code>Question</code> component that uses <code><component :is="..."></code> to dynamically display the correct question type.</p>
<p>AbstractQuestion.vue</p>
<pre><code><template>
<div>
<slot name="questionText">
<p v-html="exercise.text" />
</slot>
<!-- contains the input controls to answer the question
(e.g. checkboxes, textareas...) -->
<slot
v-if="!readOnly || !$slots.readOnlyAnswer?.()"
name="submissionControls"
></slot>
<!-- representation of a read-only answer given to the question (e.g. a code fragment for a programming exercise) -->
<slot v-else name="readOnlyAnswer"></slot>
<slot name="solution"></slot>
</div>
</template>
<script lang="ts">
import { defineComponent, PropType } from "@vue/runtime-core";
export default defineComponent({
name: "AbstractQuestion",
props: {
question: {
type: Object as PropType<Question>,
required: true,
},
readOnly: {
type: Boolean,
default: false,
},
},
});
</script>
</code></pre>
<p>Example of an "inheriting" question type:</p>
<p>OpenAnswerQuestion.vue</p>
<pre><code><template>
<AbstractQuestion v-bind="$props">
<template #submissionControls>
<TextEditor
:disabled="readOnly"
v-model="answerTextProxy"
/>
</template>
<template #readOnlyAnswer>
<p
v-html="answerTextProxy"
/>
</template>
</AbstractQuestion>
</template>
<script lang="ts">
import { defineComponent, PropType } from "@vue/runtime-core";
import TextEditor from "@/components/ui/TextEditor.vue";
import AbstractExercise from "./AbstractQuestion.vue";
export default defineComponent({
name: "OpenAnswerQuestion",
props: {
question: {
type: Object as PropType<Question>,
required: true,
},
answer: {
type: String,
default: "",
},
readOnly: {
type: Boolean,
default: false,
},
},
methods: {},
computed: {
answerTextProxy: {
get() {
return this.answer;
},
set(val: string) {
this.$emit("updateAnswerText", val);
},
},
},
components: { TextEditor, AbstractQuestion },
});
</script>
</code></pre>
<p>And the component actually exposed:
Question.vue</p>
<pre><code><template>
<component :is="questionComponentName" v-bind="$props"></component>
</template>
<script lang="ts">
import { defineComponent, PropType } from "@vue/runtime-core";
export default defineComponent({
name: "Question",
props: {
question: {
type: Object as PropType<Question>,
required: true,
},
readOnly: {
type: Boolean,
default: false,
},
},
methods: {},
computed: {
questionComponentName(): string {
const componentNames: Record<QuestionType, string> = {
[QuestionType.OPEN_ANSWER]: "OpenAnswerQuestion",
// ... rest of the mapping
};
return componentNames[this.question.questionType];
},
},
});
</script>
</code></pre>
<p>This seems to be working, but it feels kinda hacky. Is there a better way to achieve this specialization/dynamic dispatch/abstraction of components in Vue3?</p>

Jest function fails to fire after network request in react component
|
<p>Full Repo</p>
<p><a href="https://github.com/brianbancroft/sample-testing-msw-sb-jest-rtl" rel="nofollow noreferrer">https://github.com/brianbancroft/sample-testing-msw-sb-jest-rtl</a></p>
<p>Using mock service worker (msw) to respond to a network request, I have a React login component. On submit it sends a network request and on success it is supposed to trigger a "handleClose" function which is a prop to the component.</p>
<pre class="lang-js prettyprint-override"><code>async function handleSubmit(event) {
event.preventDefault();
setLoading(true);
const { username, password } = event.target.elements;
try {
const response = await fetch("/login", {
method: "POST",
mode: "cors",
cache: "no-cache",
credentials: "same-origin",
headers: {
"Content-Type": "application/json",
},
redirect: "follow",
referrerPolicy: "no-referrer",
body: JSON.stringify({
username: username.value,
password: password.value,
}),
});
await response.json();
if (response.status === 200) {
props.handleClose();
} else {
setInvalidUsernamePassword(true);
setLoading(false);
}
} catch (error) {
alert("Error detected", error);
}
}
</code></pre>
<p>When I test, I validate that the function <code>handleClose</code> is invoked.</p>
<pre class="lang-js prettyprint-override"><code>
const setup = async () => {
const handleClose = jest.fn();
const utils = await render(<Primary handleClose={handleClose} />);
const usernameField = screen.getByLabelText(/Username/);
const passwordField = screen.getByLabelText(/Password/);
const submitButton = screen.getByRole("button", {
name: /Sign In/i,
});
return {
usernameField,
passwordField,
submitButton,
handleClose,
...utils,
};
};
test("The handleClose function prop is triggered", async () => {
const { usernameField, passwordField, submitButton, handleClose } =
await setup();
fireEvent.change(usernameField, { target: { value: faker.lorem.word() } });
fireEvent.change(passwordField, { target: { value: faker.lorem.word() } });
fireEvent.click(submitButton);
expect(handleClose).toHaveBeenCalled();
});
</code></pre>
<p>This fails</p>
<pre><code>
Expected number of calls: >= 1
Received number of calls: 0
</code></pre>
<p>However, when I invoke the prop function before the start of the async function, it passes, which tells me it's not how I am passing the jest.fn() into the component.</p>
<p>I have investigated whether an error gets thrown (it doesn't), and I also know that <code>msw</code> is working as intended, and that the network request responds with a 200 unless I send a password value of "badpassword" which is used to simulate an incorrect email or password in another test in the same file.</p>
<p>I also converted the function to use promises. No change.</p>

Why some methods are not either private or public?

<p>Why is that? And when to do that?
This is my example code:</p>

Plot rows of numbers that fall within a defined proximity to other rows in R
|
<p>I have a dataframe of numbers (genetics data) on different chromosomes that can be considered factors to separate the numbers on. It looks like this (with adjacent columns containing Sample info for each position): </p>
<pre><code>awk '{print $2 "\t" $3}' log_values | head
Chr Start Sample1 Sample2
1 102447376 0.46957632 0.38415043
1 102447536 0.49194950 0.30094824
1 102447366 0.49874880 -0.17675325
2 102447366 -0.01910729 0.20264680
1 108332063 -0.03295081 0.07738970
1 109472445 0.02216355 -0.02495788
</code></pre>
<p>What I want do is to make a series of plots taking values from other columns in this file. Instead of plotting one for each row (which would represent the results in a different region and/or different sample), I want to draw plots covering ranges if there are values in the Start column close enough to each other. To start, I would like a plot to be made if there are three values in the Start column within say 1000 of each other. That is, a 1000 from A to B to C inclusive so that A to B <= 1000 and B to C is <= 1000 but A to C does not have to be <= 1000. In the code below, this 1000 is "CNV_size". The "flanking_size" variable is just to zoom the plot out a bit so I can give it some context. </p>
<p>Taking the sample values, Rows 1 2 and 3 would be highlighted as one plot for Sample1. These sample numbers are log2Ratios so I only want to plot the significant ones. I define this as above 0.4 or below -0.6. This means that the same three rows would not yield a plot for sample 2. </p>
<p>The fourth row would not be included as the Chr column number/factor is different. That's a separate plot for each column showing the values only in the rows that meet this condition. So I can have more than plot per sample but each set of regions that meets this criterion will be plotted in all samples. If this doesn't make sense, perhaps my ineffective attempt below will help explain what I'm waffling about. </p>
<pre><code>pdf("All_CNVs_closeup.pdf")

Django Rest Framework serialize additional fields from intermediate model
|
<p>I am developing a small application that lists the customers of a store. I'm trying to retrieve the additional fields of the intermediate model because a contact can belong to several stores but depending on the store it is premium or not and if he is happy or not.</p>
<p>Here's the JSON response I'd like to get for a Store like <strong>/contacts/?store=my_store</strong></p>
<pre><code>[
{
"id": "UX",
"first_name": "UX",
"last_name": "UX",
"email": null,
"mobile": null,
"happy": True,
"premium": True
},
{
"id": "AX",
"first_name": "AX",
"last_name": "AX",
"email": null,
"mobile": null,
"happy": False,
"premium": True
}
]
</code></pre>
<p>here are my models:</p>
<pre><code>class Store(BaseModel):
id = models.CharField(primary_key=True, max_length=200)
name = models.CharField(max_length=100)
class Contact(BaseModel):
id = models.CharField(primary_key=True, max_length=200)
first_name = models.CharField(max_length=100, null=True, blank=True)
last_name = models.CharField(max_length=100, null=True, blank=True)
email = models.CharField(max_length=100, null=True, blank=True)
mobile = models.CharField(max_length=100, null=True, blank=True)
stores = models.ManyToManyField(
Store, through="MemberShip", through_fields=("contact", "store")
)
class MemberShip(BaseModel):
contact = models.ForeignKey(
Contact, on_delete=models.CASCADE, related_name="contact_to_store"
)
store = models.ForeignKey(
Store, on_delete=models.CASCADE, related_name="store_to_contact"
)
happy = models.BooleanField(default=True)
premium = models.BooleanField(default=False)
</code></pre>
<p>and my serializers:</p>
<pre><code>class MemberShipSerializer(serializers.ModelSerializer):
class Meta:
model = MemberShip
fields = ("contact", "store", "happy", "premium")
class StoreSerializer(serializers.ModelSerializer):
class Meta:
model = Store
fields = ("id", "name")
class ContactSerializer(serializers.ModelSerializer):
infos = MemberShipSerializer(
source="contact_to_store" many=True, read_only=True
)
class Meta:
model = Contact
fields = (
"id", "first_name", "last_name", "email", "mobile", "infos"
)
</code></pre>
<p>As you can see, I first tried to gather all the information of the intermediate model in a field before displaying <strong>happy</strong> and <strong>premium</strong> but, strangely enough, the <strong>infos</strong> field is returned with an empty array value.

ffmpeg Python command only runs once in PM2 environment
|
<p>PM2 is running as a <code>web</code> user. ffmpeg was installed native to Ubuntu 16.04 LTS using <code>sudo apt install ffmpeg</code>. The Python version is 3.6. The software uses <a href="https://github.com/kkroening/ffmpeg-python" rel="nofollow noreferrer">ffmpeg-python@0.1.17</a>.</p>
<p>The applications spawned produce no errors. When the ffmpeg code executes for the first time, we see an output and the ffmpeg process completes the task as expected. </p>
<p>All subsequent requests stall on the next ffmpeg execution. No output. No return from the ffmpeg process. No errors. The PM2 process does not error out. The application log stalls on the ffmpeg command as though it is hung.</p>
<p><strong>What is the root cause?</strong> Any help is deeply appreciated.</p>

Initialize FileInputStream in JMH @Setup and use in @Benchmark

<p><code>InputStream</code> initiliazed in <code>@Setup</code>, when trying to use it in <code>@Benchmark</code> its closed. Changing <code>@State</code> doesn't work. Am I doing this correctly? Is there are way to avoid stream initialization overhead and do proper benchmark?</p>
<p>This doesn't work for <code>XMLStreamReader</code> also, I am doing a serialization deserialization benchmark where I want to avoid file read/stream initialization cost into benchmark score.</p>
<p>sample benchmark</p>

Janus VideoRoom plugin subscribe operation took too much seconds before i saw remote video
|
<p><br/>Im using Janus VideoRoom plugin and i want to subscribe/unsubscribe 2 or more different publishers.
<br/>First 4 or 5 subscriptions (start subscribe -> got video visible) take 2-3 seconds.
<br/>I call it <strong>NORMAL</strong>.
<br/>But next subscriptions take MUCH more time.
<br/>I call it <strong>UNNORMAL</strong>.
<br/>Please tell me where is my mistake ?</p>

Calculator GUI problems
|
<p>I'm in my first semester of programming as a first year college and we were tasked to make a calculator GUI. I'm almost done but I need to make the "Error" appear if the denominator is 0 but it outputs 0.0. My other problem is that I need the gui to restart after showing the final answer but what happens is that after I clicked equals then clicked the number it just continues. So if I press 1+1 then clicked =, it outputs 2 but when I clicked a number for example 1, it just becomes 21.</p>
<p>Also, how do I remove the .0 at the end of every answer? I tried endsWith and replace after every equation but it's not working.</p>
<pre><code> @Override
public void actionPerformed(ActionEvent e){
for(int i=0;i<10;i++) {
if(e.getSource() == numbers[i]) {
text.setText(text.getText().concat(String.valueOf(i)));
}
}
if(e.getSource()==dec) {
if (text.getText().contains(".")) {
return;
} else {
text.setText(text.getText() + ".");
}
}
if(e.getSource()==add) {
num1 = Double.parseDouble(text.getText());
operator ='+';
label.setText(text.getText() + "+");
text.setText("");
}
if(e.getSource()==sub) {
num1 = Double.parseDouble(text.getText());
operator ='-';
label.setText(text.getText() + "-");
text.setText("");
}
if(e.getSource()==mult) {
num1 = Double.parseDouble(text.getText());
operator ='*';
label.setText(text.getText() + "*");
text.setText("");
}
if(e.getSource()==div) {
num1 = Double.parseDouble(text.getText());
operator ='/';
label.setText(text.getText() + "/");
text.setText("");
}
if(e.getSource()==neg) {
Double neg = Double.parseDouble(text.getText());
neg*=-1;
text.setText(String.valueOf(neg));
}
if(e.getSource()==per) {
num1 = Double.parseDouble(text.getText())/100;
label.setText(text.getText() + "%");
text.setText(String.valueOf(num1));
label.setText("");

ExpressJS & AJAX - Session Returns Undefined
|
<h2><strong>Structure</strong></h2>
<p>I have an API hosted on a secure server with HTTPS.</p>
<p>as such: <code>https://example.com</code></p>
<p>Also, I have a frontend <code>index.html</code> located on my Desktop.</p>
<hr />
<h2><strong>Goal</strong></h2>
<p>I would like to send an ajax post request to the api and have the api save a value in the session and retrieve it. Like so:</p>
<ol>
<li>Index.html makes POST ajax request to API</li>
<li>API saves a value in session</li>
<li>Index.html makes POST ajax request to API</li>
<li>API prints out the value in session</li>
</ol>
<hr />
<h2>API Code</h2>
<p>First I allowed connections from all origins by using <code>cors()</code>.
And I have set up my <code>session()</code> as so.</p>
<pre><code>app.use(
cors({
origin: true,
optionsSuccessStatus: 200,
credentials: true,
})
);
app.options(
'*',
cors({
origin: true,
optionsSuccessStatus: 200,
credentials: true,
})
);
app.use(session({
secret: "wefwefwe",
cookie: {
sameSite: "none",
secure: false,
maxAge: 360000000
},
saveUninitialized: false
}))
</code></pre>
<p>And then there's these 2 routes which will be called by the <code>index.html</code></p>
<pre><code>app.post('/createSession', async (req, res) => {
req.session['test'] = "HIIIII";
res.send("200");
})
app.post('/getSession', async (req, res) => {
console.log(req.session['test']);
res.send("200");
})
</code></pre>
<hr />
<h2>AJAX Code</h2>
<p>There are 2 ajax calls, one is to create the session and the other is to retrieve the session.</p>
<pre><code>$.ajax({
url: `https://example.com/createSession`,
type: "POST",
dataType: "json",
crossDomain: true,
xhrFields: { withCredentials: true },
success: function (result) {
console.log(result);
}
});
$.ajax({
url: `https://example.com/getSession`,
type: "POST",
dataType: "json",
crossDomain: true,
xhrFields: { withCredentials: true },
success: function (result) {
console.log(result);
}
});
</code></pre>
<hr />
<h2>Problem</h2>
<p>Upon POST to <code>/createSession</code>, I received this issue
<a href="https://i.stack.imgur.com/sWuoW.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/sWuoW.png" alt="enter image description here" /></a></p>
<p>However, when I changed secure to true - <code>secure: true</code>, The <code>/createSession</code> request doesn't even contain a <code>set-cookie</code> header.</p>
<p>Thus, when I POST to <code>/getSession</code>, it shows as <code>undefined</code>.</p>
<p>Could someone help me out with this please? For some reason I seem to get stuck with sessions on almost every project I embark on. :/</p>

Add and edit form in one page

Get prop that passed from child component
|
<p>I have an react native app where I render map in App.js and this is the states of App.js:</p>
<pre><code>this.state = {
region: null,
shops: [
{
name: "name",
rating: 0,
coords: {
latitude: 543543,
longitude: 656546
}
}
]
};
</code></pre>
<p>and this is the render code of it:</p>
<pre><code> render() {
const { region, shops } = this.state;
return (
<SafeAreaView style={styles.container}>
<Map region={region} places={shops} />
</SafeAreaView>
);
}
</code></pre>
<p>as you can see I pass the shops state to Map component and in map component I have this main render to render the MapView:</p>
<pre><code>render() {
const region = this.props.region;
return (
<MapView
style={styles.container}
region={region}
showsUserLocation
showsMyLocationButton
>
{this.renderMarkers()}
</MapView>
);
</code></pre>
<p>you can see the this.renderMarkers() where the markers of shops exist:</p>
<pre><code>renderMarkers() {
return this.props.places.map((marker, i) => (
<Marker key={i} title={marker.name} coordinate={marker.coords} >
<View style={{
flexDirection: 'row', width: 70, height: 60,
backgroundColor: 'none',
}}>
<Svg
width={60} height={50}>
<Image
href={require('icon.png')}
/>
<Rating rating={marker.rating} />
</Svg>
</View>
</Marker>
));
}
</code></pre>
<p>each marker contain Image and Rating components and what I'm trying to do it to pass the rating like this: rating={marker.rating} to the component of Rating</p>
<p>now in the Rating component I'm trying to get the rating like this:</p>
<pre><code>render() {
let ratings = this.props.places;
let stars = [];
for (var i = 1; i <= 5; i++) {
if (i > ratings.rating) {
// do something
}
}
return (
<View style={styles.container}>
{ stars }
</View>
);
}
</code></pre>
<p>now you understand that I pass the whole object of states from App component to Map component then I want to pass only the rating prop from Map component to Rating component
how to do that?</p>

Pass a named list of models to anova.merMod
|
<p>I want to be able to pass a named list of models (merMod objects) to anova() and preserve the model names in the output. This is particularly useful in the context of using mclapply() to run a batch of slow models like glmers more efficiently in parallel. The best I've come up with is to use do.call on a de-named version of the model list, but that's not ideal because I might have models named (say) "mod12", "mod17", and "mod16" and these model names get translated to "MODEL1", "MODEL2", and "MODEL3" in the output. (That might seem trivial when looking at a single batch, but over the course of a long modeling session with dozens of models it's a surefire recipe for confusion.)</p>
<p>Note that this isn't the same issue as <a href="https://stackoverflow.com/questions/18108045/create-and-call-linear-models-from-list">Create and Call Linear Models from List</a> because I'm not trying to compare pairs of models across lists. It's also more complex than <a href="https://stackoverflow.com/questions/15172738/using-lapply-on-a-list-of-models">Using lapply on a list of models</a> because I'm using anova() in a non-unary way.</p>
<p>Here's a minimal reprex:</p>
<pre><code>library(lme4)
formList <- c(mod12 = angle ~ recipe + temp + (1|recipe:replicate),
mod17 = angle ~ recipe + temperature + (1|recipe:replicate),
mod16 = angle ~ recipe * temperature + (1|recipe:replicate))
modList <- lapply(formList, FUN=lmer, data=cake)
# Fails because modList is named so it's interpreted as arg-name:arg pairs
do.call(anova, modList)
# Suboptimal because model names aren't preserved
do.call(anova, unname(modList))
# Fails because object isn't merMod (or some other class covered by methods("anova"))
do.call(anova, list(object=modList[1], ...=modList[-1], model.names=names(modList)))
</code></pre>
<p>The second do.call returns this:</p>
<pre><code>Data: ..1
Models:
MODEL1: angle ~ recipe + temp + (1 | recipe:replicate)
MODEL2: angle ~ recipe + temperature + (1 | recipe:replicate)
MODEL3: angle ~ recipe * temperature + (1 | recipe:replicate)
Df AIC BIC logLik deviance Chisq Chi Df Pr(>Chisq)
MODEL1 6 1708.2 1729.8 -848.08 1696.2
MODEL2 10 1709.6 1745.6 -844.79 1689.6 6.5755 4 0.1601
MODEL3 20 1719.0 1791.0 -839.53 1679.0 10.5304 10 0.3953
</code></pre>
<p>Ideally, the output would look like this:</p>
<pre><code>Data: ..1
Models:
mod12: angle ~ recipe + temp + (1 | recipe:replicate)
mod17: angle ~ recipe + temperature + (1 | recipe:replicate)
mod16: angle ~ recipe * temperature + (1 | recipe:replicate)
Df AIC BIC logLik deviance Chisq Chi Df Pr(>Chisq)
mod12 6 1708.2 1729.8 -848.08 1696.2
mod17 10 1709.6 1745.6 -844.79 1689.6 6.5755 4 0.1601
mod16 20 1719.0 1791.0 -839.53 1679.0 10.5304 10 0.3953
</code></pre>
<p>How do I do this? I'm more than happy with an ugly wrapper around anova() if it means I get a more intelligible output.</p>

PHP cURL GET request is not returning JSON object
|
<p>I'm attempting to use PHP cURL to write a GET request that returns information in JSON format so I can decode it and store the header values accordingly in a Response class. My request goes through successfully with a 200 Status code, but the actual response is coming back as a string rather than an object that I can work with. I am using the generated code from Postman for cURL.</p>
<p>Here my PHP code for the request:</p>
<pre><code>
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => "http://example.com",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 0,
CURLOPT_FOLLOWLOCATION => true,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "GET",
CURLOPT_HEADER => 1,
CURLOPT_HTTPHEADER => array('Content-Type: application/json',
'Accept: application/json')
));
$result = curl_exec($curl);
curl_close($curl);
var_dump($result);
</code></pre>
<p>And here is the result I get from the var_dump($result):</p>

<p>I installed Rais and Ruby 2.x via RVM months ago when I was using OSX 10.6. Today I made blunder to try installing <code>PhantonJS</code> via HomeBrew. it also tried to install <code>openssl-1.0.1i.tar.gz</code> and installed too. I could not install PhantomJS as it was taking time but resta assured OpenSSL was installed. This evening when I tried to load <code>RubyMine</code> for work I got following errors:</p>

Networking not working on Docker / Centos 7.9
|
<p>I'm running Docker on Centos 7.9.2009 and have a very strange issue. The containers do not have network access and cannot be accessed from the host. I've searched for potential solutions, a lot of which seem to be related to DNS issues (which I don't think is what's going on here since even pinging 8.8.8.8 from within the container does not work). I've tried installing iptables-service, restarting iptables & docker in that order, full reboot etc.</p>
<p>In my efforts to try and find what the problem might be, I ran tcpdump in a separate terminal. As soon as I did, everything works fine! Kill the tcpdump process and it all stops - no network access. Any suggestions of why running tcpdump may resolve the problem? Is it something to do with tcpdump listening on docker0 and establishing a network state?</p>

Using LESS how to target the granparent from child element?

<p>I'm trying to target a specific popover that a div with class "s-formgroup" and set its background RED as I have multiple popovers. Either my js nor my less do the trick</p>

<pre><code><div class="popover>

<pre><code>.popover {

Is there a way to pass certain info, that is specific to a user, to the fields of a (new) django form?
|
<p>I have the following "problem":
I have automated a "prediction-game" where users can win points when they predict the correct winners in a sports event over multiple weeks (for example: Tour de France).
They are allowed to choose 5 athletes of which they think that will win in the races.
At the end of every week, the users are allowed to make some changes in their prediction for the next week.</p>
<p>Until a certain date (start of the event or week), the users can choose athletes for their prediction. The users can fill in the form and if they change their minds before the start, they are still able to change/update their prediction. But after the start, they can't change it anymore and their input will be used to calculate their score. After the first week (in which their scores are calculate with the input they made in the "PredictionWeek1" model), they will have a change to make a new prediction for the next week ("PredictionWeek2" model) for which they also have the change to update it as much as they want before a certain date.</p>
<p>In reality, the input for the second week, will be very similar to the first week: the users probably only want to change one or two athletes. Therefore, and this is the question, it will be best that the input form of "PredictionWeek2" is already filled in with their predictions for week 1, so that they don't have to select every athlete again.</p>
<p>I have already tried to look for a way that their input from "PredictionWeek1" gets passed to the "default" argument for the 'charfield' in the models, but without any luck: I do not get it to be user specific...
I also tried to do something similar as the "UpdateView", but this was also not a solution the input for PredictionWeek2 can't be an "update" for PredictionWeek1: the point calculations in the first week need to be done with the input of PredictionWeek1 and the point calculations for the second week need to be done with the input of PredictionWeek2, so this need to be always a seperate input)</p>
<p>The used code below (a little bit simplified for better comprehension):</p>
<p>In views.py:</p>
<p>class PredictionWeek1CreateView(LoginRequiredMixin, CreateView):</p>
<pre><code>model = PredictionWeek1
fields = ['prediction1', 'prediction2', 'prediction3', 'prediction4', 'prediction5']
def form_valid(self, form):

prediction = self.get_object()

return True
return False

CSS file is styling unintended elements
|
<p>Bear with me as I am new to web development and will try to explain my issue properly.</p>
<p>So basically I'm trying to style a certain element on my web page but the issue is that it is also applying that styling to the footer as well, which is not what I want. Here's what I'm trying to achieve:</p>
<pre><code><div id="message" class="bg-dark">
<div class="container-fluid padding">
<div class="row text-center padding">
<div class="col-md-12 col-lg-6">
<h2>CEO's Message</h2>
<p>content</p>
</div>
<div class="col-lg-5">
<img src="images/ceo.jpg" class="img-fluid">
</div>
</div>
<hr class="my-4">
</div>
</div>
</code></pre>
<p>Now, I've even given the id tag to specifically style this div.</p>
<p>and the footer is as follows:</p>
<pre><code><footer>
<div class="container-fluid padding">
<div class="row text-center">
<div class="col-md-4">
<img src="images/irco.png">
<hr class="light">
<p>(+92)51 21301</p>
<p>info@irco</p>
<p>address</p>
<p>address</p>
<p>address</p>
</div>
<div class="col-md-4">
<hr class="light">
<h5>Information</h5>
<hr class="light">
<p>About Us</p>
<p>Help Desk</p>
<p>Support</p>
<p>Privacy Policy</p>
<p>Terms & Conditions</p>
</div>
<div class="col-md-4">
<h5>Subscribe to our newsletter</h5>
<p>Stay updated with all the latest updates.</p>
</div>
<div class="col-12">
<hr class="light">
<h5>&copy; irco</h5>
</div>
</div>
</div>
</footer>
</code></pre>
<p>And the styling done in the CSS file:</p>
<pre><code>#message h2, p{
color: white;
padding-top: 4rem;
}
footer{
background-color: #3f3f3f;
color: #d5d5d5;
padding-top: 2rem;
}
</code></pre>
<p>Now, even that white color and the 4rem padding is being applied to the footer and the padding is being applied in between the <p> elements so everything's all stretched out and I can't figure out what I am doing wrong here. What I want is to just simply apply the white color and the padding to the #message portion and leave the footer alone.</p>

<p>I believe the problem starts and will be solved by fixing the trace at item #4 where the following is called: <code>Illuminate\Queue\Jobs\Job->resolve(NULL)</code>. I see this in both failing jobs on the GoDaddy server, but it does not happen in local. I don't know enough about laravel to understand where the NULL value is coming from and how to fix it. This occurs before the job class is loaded, but it does not happen for all queued jobs. Only jobs of this class.</p>
<p>In both the local copy and the production copy I use the GoDaddy databases, so both systems talk to the same database host. I use a database named CMP_dev and CMP_core to differentiate between the development and production tables. Because I am using the same database source, I can rule out changes in the mysql settings.</p>
<p>I upgraded all composer packages and retested. Then, I committed the composer.lock file and updated the GoDaddy server to match. So, I can rule out problems with old buggy code that have already been fixed by someone else.</p>
<p>The PHP version on the server is 7.3.11, and the PHP version on local dev is 7.3.6. The good news is that they are both 7.3.X, which reduces risk of language variations, but there still may be an issue between 7.3.6 and 7.3.11, but GoDaddy does not allow me to control the PHP setting beyond the minor version number of 7.3.</p>
<p>---- Added on January 09, 2020------
I thought it might be the difference in web servers. On my local machine, I use <code>php artisan serve</code> to host the software. On GoDaddy, I use Nginx. However, then I realized that it is not the server that runs the queue. The command line runs the queue, and both commands are being run using <code>php artisan schedule:run</code>. This rules out the web server software and all its components.
-<em>-</em>-<em>-</em>-<em>-</em>-<em>-</em>-</p>
<p>I have successfully run queued mail jobs, which means that the queue works. This should localize the issue to the two classes that are generating problems for me. If I can find the issue with one, I will likely find the issue with the second, so I will include the first job causing issue here:</p>
<p>app/Jobs/ConvertCsvFileToIntermediateFile.php:
<pre><code>namespace App\Jobs;
use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Foundation\Bus\Dispatchable;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Queue\SerializesModels;
use App\ContactCsvFile;
use Illuminate\Support\Facades\Log;
class ConvertCsvFileToIntermediateFile implements ShouldQueue
{
use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;
public $timeout = 500;
/** @var ContactCsvFile */
private $file;
private $delegate;
/**
* Create a new job instance.
*
* @return void
*/
public function __construct(ContactCsvFile $file, $delegate = null)
{
$this->file = $file;
$this->delegate = $delegate;
}
/**
* Execute the job.
*
* @return void
*/
public function handle()
{
$this->file->process($this->delegate);
}
}
</code></pre>
<p>The error is occurring before handle() is ever called. I know this because, when I include a <code>dd($this->file)</code> as the first line of handle, the line is never reached.</p>
<p>Also, I think it is important to note that when most jobs fail, their class name is listed in the queue:failed table. But in this case, the queue:failed table reads the time: "2020-01-08 09:23:23."</p>

"The replica master 0 ran out of disk." During Sklearn Fit in Google Cloud ML Engine
|
<p>I'm trying to use Google Cloud ML Engine to do an <code>sklearn LDA gridsearch</code> on 500 MB data (10000 rows x 26000 columns) to find what number of topics would be the best for my topic modeling project.</p>
<p>The maximum number of iterations for each CV fold was set to 100.
After 47 iterations, the job would fail, citing the below error. I tried this using <code>BASIC</code> tier, <code>STANDARD</code> tier, and a <code>CUSTOM</code> tier with <code>masterType=complex_model_m</code>, and the same error happened every time.</p>
<p>I can't find much else on stackoverflow that talks about this problem, although I did come across <a href="https://stackoverflow.com/questions/55452871/solved-no-space-left-on-device-in-google-cloudml-basic-tier-what-is-the-disk">this link</a>, which seems to be related in some way. A solution was provided by the original asker:</p>
<pre><code>Solved : This error was coming not because of Storage Space instead coming because of shared memory tmfs. The sklearn fit was consuming all the shared memory while training. Solution : setting JOBLIB_TEMP_FOLDER environment variable , to /tmp solved the problem.
</code></pre>
<p>I'm afraid I'm not entirely sure how to interpret or implement the solution.</p>
<p>Here are the three lines relevant to where the problem comes from:</p>
<pre><code>lda = LatentDirichletAllocation(learning_method='batch', max_iter=100, n_jobs=-1, verbose=1)
gscv = GridSearchCV(lda, tuned_parameters, cv=3, verbose=10, n_jobs=1)
gscv.fit(data)
</code></pre>
<p>and I would call the job in the format:</p>
<pre><code>gcloud ai-platform jobs submit training $JOB_NAME \
--package-path $TRAINER_PACKAGE_PATH \
--module-name $MAIN_TRAINER_MODULE \
--job-dir $JOB_DIR \
--region $REGION \
--config config.yaml
</code></pre>
<p>This is the absolutely abhorrent error message in the logs:</p>

<p>The most important of which I can only assume is:</p>
<p><code>OSError: [Errno 28] No space left on device</code></p>
<p>The message: <code>The replica master 0 ran out of disk.</code> was the official cause of the problem according to the console.</p>
<p>I can run this on my own desktop to 100 iterations no problem. Any insight on what's happening is greatly appreciated. Thank you!</p>

Overflow:hidden not working

<p>When I run my code in a browser, the background is exactly where I already want it to be, the problem is that I can still scroll down, revealing the part of the background which is originally hidden.

How to set the environment when using `conda build`?
|
<p>Trying to take advantage of Conda's build function to install a package not in conda repositories. I've downloaded the source files for the package I want. At the same level I created a folder for my <em>conda recipes</em> which contains the <code>meta.yaml</code> setting <code>source: path: ../<package-name></code>. So, <em>look up one directory to find the source files</em>. This works.</p>
<p>The problem happens at the end when build attempts to test importing the package. It says <em>x module not found</em>, but I'm invoking <code>conda build</code> from a conda environment where the missing package is installed as shown by <code>conda list</code>. </p>
<p>How do I know from what environment <code>conda build</code> is performing these tests?</p>
<p>How to set the environment when using <code>conda build</code>?</p>
<p>Doesn't help that <a href="https://conda.io/projects/conda-build/en/latest/index.html" rel="nofollow noreferrer">Conda Build</a> docs are full of the word <em>environment</em>, but which mostly refers to <a href="https://docs.conda.io/projects/conda-build/en/latest/user-guide/environment-variables.html" rel="nofollow noreferrer">environmental variables</a> and not <a href="https://docs.conda.io/projects/conda/en/latest/user-guide/concepts/environments.html" rel="nofollow noreferrer">conda environments</a></p>

Plotting polygons from SQL type geo column in Python
|
<p>I have an Sqlite database with a table that includes a geo column. When I add this table into QGIS as a layer, it shows a map of Chicago with polygons as shown below. I think, the polygon points are stored in the column named geo.</p>
<p><a href="https://i.stack.imgur.com/ZZvh2.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ZZvh2.png" alt="enter image description here" /></a></p>
<p>I am trying to plot the same in Python to be able to add more things on top of this layout using Matplotlib. To begin with, I could load the table named "Zone" in Python using the following (that I wrote):</p>
<pre><code>import sqlite3 # Package for SQLite
### BEGIN DEFINING A READER FUNCTION ###
def Conditional_Sqdb_reader(Sqdb,Tablename,Columns,Condition):
conn = sqlite3.connect(Sqdb) # Connects the file to Python
print("\nConnected to %s.\n"%(Sqdb))
conn.execute('pragma foreign_keys = off') # Allows making changes into the SQLite file
print("SQLite Foreign_keys are unlocked...\n")
c = conn.cursor() # Assigns c as the cursor
print("Importing columns: %s \nin table %s from %s.\n"%(Columns,Tablename,Sqdb))
c.execute('''SELECT {columns}
FROM {table}
{condition}'''.format(table=Tablename,
columns=Columns,
condition=Condition)) # Selects the table to read/fetch
Sql_headers = [description[0] for description in c.description]
Sql_columns = c.fetchall() # Reads the table and saves into the memory as Sql_rows
print("Importing completed...\n")
conn.commit() # Commits all the changes made
conn.execute('pragma foreign_keys = on') # Locks the SQLite file
print("SQLite Foreign_keys are locked...\n")
conn.close() # Closes the SQLite file
print("Disconnected from %s.\n"%(Sqdb))
return Sql_headers,Sql_columns
### END DEFINING A READER FUNCTION ###
Sqdb = '/mypath/myfile.sqlite'
Tablename = "Zone" # Change this with your desired table to play with
Columns = """*""" # Changes this with your desired columns to import
Condition = '' # Add your condition and leave blank if no condition
headings,data = Conditional_Sqdb_reader(Sqdb,Tablename,Columns,Condition)
</code></pre>
<p>The data on the table is stored in "data" as a list. So, <code>data[0][-1]</code> yields the geo of the polygon of the first row, which looks something like: <code>b'\x00\x01$i\x00\x00@\xd9\x94\x8b\xd6<\x1bAb\xda7\xb6]\xb1QA\xf0\xf7\x8b\x19UC\x1bA\x9c\xde\xc5\r\xc3\xb1QA|\x03\x00\x00\x00\x01\x00\x00\x00\x06\x00\x00\x00Hlw\xef-C\x1bA\x9c\xde\xc5\r\xc3\xb1QA\xf0\xf7\x8b\x19UC\x1bAv\xc0u)^\xb1QA\xbcw\xd4\x88\xf1<\x1bAb\xda7\xb6]\xb1QA\xa5\xdc}n\xd7<\x1bA\x84.\xe1r\xbe\xb1QA@\xd9\x94\x8b\xd6<\x1bA\xce\x8eT\xef\xc1\xb1QAHlw\xef-C\x1bA\x9c\xde\xc5\r\xc3\xb1QA\xfe'</code> I do not know how to decode this and convert to a meaningful series of points, but that is what it is and QGIS apparently can do it with no hassle. How can I plot all these polygons in Python while being able to add other things within the Matplotlib world later on?</p>

Insert a dict into a sql table

ReactJS issue with map and find
|
<p>so i have an array of this type,</p>
<pre><code> (5) [{…}, {…}, {…}, {…}, {…}]
0: {naam: "Tafel 1 ", id: 1, aantalPersonen: 3, aantalMinuten: 3, bezet: 1, …}
1: {naam: "Tafel 2 ", id: 2, aantalPersonen: 1, aantalMinuten: 3, bezet: 1, …}
2: {naam: "Tafel 3 ", id: 3, aantalPersonen: 2, aantalMinuten: 6, bezet: 1, …}
3: {naam: "Tafel 4", id: 4, aantalPersonen: 0, bezet: 0, tafelLayout: {…}}
4: {naam: "Tafel 5", id: 5, bezet: 0, aantalPersonen: 0, tafelLayout: {…}}
length: 5
__proto__: Array(0)
</code></pre>
<p>i can map it to a component which then renders them all in divs and that works perfectly. Now what i want to do is render just a specific one.</p>
<pre><code>this.state.tafels.find(tafel =>(tafel.id = 1))
</code></pre>
<p>finds for example the one i want to use</p>
<p>it has to be mapped to a component using props </p>
<pre><code> <PlattegrondResto
tafelNr={tafel.id}
tafelNaam = {tafel.naam}
tafelLayout={tafel.tafelLayout}
tafelaantalPersonen={tafel.aantalPersonen}
tafelMinuten = {tafel.aantalMinuten}
tafelBezet = {tafel.bezet}
tafelSelect={(tafelNr) => this.tafelSelect(tafelNr)}
tafelTijdInterval = {this.state.tijdInterval}
/>
</code></pre>
<p>is there any way i can do that effectively ?
i tried everything i can think of so far</p>
<p>to map them all i use </p>
<pre><code> {this.state.tafels.map((tafel) =>
<PlattegrondResto
tafelNr={tafel.id}
tafelNaam = {tafel.naam}
tafelLayout={tafel.tafelLayout}
tafelaantalPersonen={tafel.aantalPersonen}
tafelMinuten = {tafel.aantalMinuten}
tafelBezet = {tafel.bezet}
tafelSelect={(tafelNr) => this.tafelSelect(tafelNr)}
tafelTijdInterval = {this.state.tijdInterval}
/>
)}
</code></pre>
<p>so i want to know is there a way to first use find and then map it to the component that is shown below</p>
<p>Thanks in advance</p>

use a custom function to find all words in a column
|
<p><strong>Background</strong></p>
<p>The following question is a variation from <a href="https://stackoverflow.com/questions/56826420/unnest-grab-keywords-nextwords-beforewords-function">Unnest grab keywords/nextwords/beforewords function</a>. </p>
<p><strong>1)</strong> I have the following <code>word_list</code></p>
<pre><code>word_list = ['crayons', 'cars', 'camels']
</code></pre>
<p><strong>2)</strong> And <code>df1</code></p>
<pre><code>l = ['there are many crayons, in the blue box crayons that are',
'cars! i like a lot of sports cars because they go fast',
'the camels, in the middle east have many camels to ride ']
df1 = pd.DataFrame(l, columns=['Text'])
df1
Text
0 there are many crayons, in the blue box crayons that are
1 cars! i like a lot of sports cars because they go fast
2 the camels, in the middle east have many camels to ride
</code></pre>
<p><strong>3)</strong> I also have a function <code>find_next_words</code> which uses <code>word_list</code> to grab words from <code>Text</code> column in <code>df1</code></p>
<pre><code>def find_next_words(row, word_list):
sentence = row[0]
trigger_words = []
next_words = []
for keyword in word_list:
words = sentence.split()
for index in range(0, len(words) - 1):
if words[index] == keyword:
trigger_words.append(keyword)
next_words.append(words[index + 1:index + 3])
return pd.Series([trigger_words, next_words], index = ['TriggerWords','NextWords'])
</code></pre>
<p><strong>4)</strong> And it's pieced together with the following</p>
<pre><code>df2 = df1.join(df.apply(lambda x: find_next_words(x, word_list), axis=1))
</code></pre>
<p><strong>Output</strong></p>
<pre><code> Text TriggerWords NextWords
0 [crayons] [[that, are]]
1 [cars] [[because, they]]
2 [camels] [[to, ride]]
</code></pre>
<p><strong>Problem</strong></p>
<p><strong>5)</strong> The output misses the following </p>
<p><code>crayons,</code> from row <code>0</code> of <code>Text</code> column <code>df1</code></p>
<p><code>cars!</code> from row <code>1</code> of <code>Text</code> column <code>df1</code></p>
<p><code>camels,</code> from row <code>2</code> of <code>Text</code> column <code>df1</code></p>
<p><strong>Goal</strong></p>
<p><strong>6)</strong> Grab all corresponding words from <code>df1</code> even if the words in <code>df1</code> have a slight variation e.g. <code>crayons,</code> <code>cars!</code> from the words in <code>word_list</code> </p>
<p><em>(For this toy example, I know I can easily fix this problem by just adding these word variations to <code>word_list = ['crayons,','crayons', 'cars!',</code>cars<code>, 'camels,', 'camels'].</code> But this would be impractical to do with my my real word_list, which contains ~20K words)</em></p>
<p><strong>Desired Output</strong></p>
<pre><code>Text TriggerWords NextWords
0 [crayons, crayons] [[in, the], [that, are]]
1 [cars, cars] [[i,like],[because, they]]
2 [camels, camels] [[in, the], [to, ride]]
</code></pre>
<p><strong>Questions</strong></p>
<p>How do I 1) tweak my <code>word_list</code> (e.g. regex?) 2) or <code>find_next_words</code> function to achieve my desired output?</p>

MediaWiki $wgUser to $this->getUser() and $context->getUser() not working
|
<p>I am learning Mediawiki and looking at some of the extensions.</p>
<p><a href="https://www.mediawiki.org/wiki/Manual:$wgUser" rel="nofollow noreferrer">Manual:$wgUser</a> on mediawiki.org states the global variable <code>$wgUser</code> should not be used for new code.</p>
<p><a href="https://www.mediawiki.org/wiki/Manual:RequestContext.php" rel="nofollow noreferrer">Manual:RequestContext.php</a> says the context object should be used instead, by using either <code>$this->getUser()</code> or <code>$context->getUser()</code>.</p>
<p>However, when I try to use <code>$this->getUser()->getName()</code> in the extension for Who's Online I get the following error:</p>
<pre><code>Fatal error: Using $this when not in object context in /home/ghsfhaco/public_html/wiki/extensions/WhosOnline/WhosOnlineHooks.php on line 19
</code></pre>
<p>And when I change it to <code>$context->getUser()->getName()</code> I get this error:</p>
<pre><code>Fatal error: Call to a member function getUser() on null in /home/ghsfhaco/public_html/wiki/extensions/WhosOnline/WhosOnlineHooks.php on line 19
</code></pre>
<p>The full <a href="https://www.mediawiki.org/wiki/Extension:WhosOnline" rel="nofollow noreferrer">Extension:WhosOnline</a> can be found at Mediawiki, but here's the specific page:</p>
<pre><code> class WhosOnlineHooks {
// update online data
public static function onBeforePageDisplay() {
global $wgUser;
// write to DB (use master)
$dbw = wfGetDB( DB_MASTER );
$now = gmdate( 'YmdHis', time() );
// row to insert to table
$row = array(
'userid' => $wgUser->getId(),
'username' => $wgUser->getName(),
'timestamp' => $now
);
$method = __METHOD__;
$dbw->onTransactionIdle( function() use ( $dbw, $method, $row ) {
$dbw->upsert(
'online',
$row,
array( array( 'userid', 'username' ) ),
array( 'timestamp' => $row['timestamp'] ),
$method
);
} );
return true;
}
public static function onLoadExtensionSchemaUpdates( $updater ) {
$updater->addExtensionUpdate( array( 'addTable', 'online',
__DIR__ . '/whosonline.sql', true ) );
return true;
}
}
</code></pre>
<p>How exactly should it be done?</p>
<p>BTW, I'm using Mediawiki 1.28.0.</p>

How to normalise my data
|
<p>First post i have been lurking for many years but finally stumped enough to ask for help? Please excuse the formatting</p>
<p>I have generated a mind map (categories, subcategories, questions and responses) Im trying to find a data structure to map this. Once I map the data I end up with lots of repetition where a question and its children fit under multiple categories and subcategories. This leads me to believe my structure is poor and this can be normalised in some way which is eluding me.</p>
<p>E.g. <strong>Thinking of shopping and advertising, which of the following have you ever done?</strong> </p>
<ul>
<li>(cat_id = 1) SHOPPING & ADVERTISING (parent Category)
<ul>
<li>(cat_id = 41) Shopping information/Purchases (Sub category)
<ul>
<li>(ID- 1234) Thinking of shopping and advertising, which of the following have you ever done?
<ul>
<li>(ID- 4111) How often do you do this via your TV screen?</li>
<li>(ID- 4112) How often do you do this via your desktop computer?</li>
<li>(ID- 4113) How often do you do this via your laptop computer?</li>
</ul></li>
</ul></li>
</ul></li>
<li><p>(cat_id = 1) SHOPPING & ADVERTISING (parent Category)</p>
<ul>
<li>(cat_id = 44) No split - shopping and advertising (Sub category)
<ul>
<li>(ID- 1234) Thinking of shopping and advertising, which of the following have you ever done?
<ul>
<li>(ID- 4111) How often do you do this via your TV screen?</li>
<li>(ID- 4112) How often do you do this via your desktop computer?</li>
<li>(ID- 4113) How often do you do this via your laptop computer?</li>
</ul></li>
</ul></li>
</ul></li>
<li><p>(cat_id = 2) SCREENS & DEVICES (parent Category)</p>
<ul>
<li>(cat_id = 51)Usage/Shared usage (Sub category)
<ul>
<li>(ID- 1234) Thinking of shopping and advertising, which of the following have you ever done?
<ul>
<li>(ID- 4111) How often do you do this via your TV screen?</li>
<li>(ID- 4112) How often do you do this via your desktop computer?</li>
<li>(ID- 4113) How often do you do this via your laptop computer?</li>
</ul></li>
</ul></li>
</ul></li>
<li>(cat_id = 2) SCREENS & DEVICES (parent Category)
<ul>
<li>(cat_id = 52)TV (Sub category)
<ul>
<li>(ID- 1234) Thinking of shopping and advertising, which of the following have you ever done?
<ul>
<li>(ID- 4111) How often do you do this via your TV screen?</li>
</ul></li>
</ul></li>
</ul></li>
</ul>
<p>So in order to map this i created the following table. Please note I already have a Question table and a category table that link to this, that contains the IDs above.</p>
<pre><code>| id | object_id | parent_id | type |
|---- |----------- |----------- |------ |
| 1 | 1 | NULL | 1 |
| 2 | 41 | 1 | 1 |
| 3 | 1234 | 41 | 2 |
| 4 | 4111 | 1234 | 2 |
| 5 | 4112 | 1234 | 2 |
| 6 | 4113 | 1234 | 2 |
| 7 | 44 | 1 | 1 |
| 8 | 1234 | 44 | 2 |
| 9 | 4111 | 1234 | 2 |
| 10 | 4112 | 1234 | 2 |
| 11 | 4113 | 1234 | 2 |
| 12 | 2 | NULL | 1 |
| 13 | 51 | 2 | 1 |
| 14 | 1234 | 51 | 2 |
| 15 | 4111 | 1234 | 2 |
| 16 | 4112 | 1234 | 2 |
| 17 | 4113 | 1234 | 2 |
| 18 | 52 | 2 | 1 |
| 19 | 1234 | 52 | 2 |
| 20 | 4111 | 1234 | 2 |
| 21 | 4112 | 1234 | 2 |
| 22 | 4113 | 1234 | 2 |
</code></pre>
<p>As you can see above there is a lot of repetition. Other than the ID given for the table 4,5,6,9,10,11,15,16,17,20,21,22 is the same data. which makes me think this isn't the most efficient way if approaching this. I have a feeling I should be splitting this out by object ID and then having all parent but then I start to lose track and get lost. This is a small sample the above example is repeated a lot of times in the mind map as i can be access through multiple paths</p>
<p>Can anyone help? Is it possible or is what I have done sufficient.</p>

ListView items does not fit in Grid cells
|
<p>Help me please. In Xamarin.Forms I have a main ListView containing cards (Frame with Grid). Each Grid has Labels and a ListVew with phones. The ListVew with phones takes up three rows and three columns. I need all the elements of the phone ListView inside the Grid to always be visible (usually their number is up to three, but maybe more) and that the height of the Grid cells will increase if necessary to accommodate all the elements of the phone ViewList. Is this possible to do? Now Grid cells increase in text height in labels but not in PhoneListView height.</p>
<pre><code>[MyListView MainView = new MyListView

<p>please Check it out and tell me the reason behind. I was following a video tutorial on how to create a map based app and suddenly when I reached at a point to use Fused Location Api I got stuck. The Build Gradle code in the tutorial was different than mine so I thing that this can be the reason for the FusedLocationApi to not work properly.</p>

Comparing old and new prices in a bootstrap thumbnail?
|
<p>As can be seen from the code below I am dynamically generating thumbnails using the template in <code>var sProductTemplate</code>. The thhumbnails are populated via ajax request which is getting the information from a json file.</p>
<p>My task is to compare the current price in the thumbnail vs the updated price in the json(if such) and display a green arrow in the thumbnail if the new price is higher than the old. If the new price is lower then the old one then I must display a red arrow.</p>
<p><strong>My problem</strong> is that I cannot really get to this point, since I cannot figure out how to save the old price and then compare it to the new price for each thumbnail.</p>
<p>Since each thumbnail has a unique id the i've written this code to get the price from the dom by the thumbnail's id's : </p>
<pre><code>var sPriceInDom = Number($("#product-id-"+sProductId+" .product-price").text());
</code></pre>
<p>But, of course, this gives me the last price and I cannot really compare it to the old price, since it is replaced by the new price.</p>
<p>If I place this code right after the ajax request, then it gives me just zeroes, since the thumbnail is dynamically generated and it has to be populated first.</p>
<p>Does anyone have an idea how can I keep the old price and compare it to the lastly updated one, so I can calculate the difference?</p>
<p>Here is all the neccesary code : </p>
<pre><code>var sProductTemplate = '<div class="col-sm-6 col-md-3"> \
<div class="thumbnail"> \
<div id="product-id-{{product-id}}" class="product"> \
<img class="imgProduct" src="{{product-icon}}" alt="idiot forgot icon"> \
<div class="caption"> \
<h3>{{product-name}}</h3> \
<div class="product-price">{{product-price}}</div> \
<i {{arrow-updown}}></i> \
</div> \
</div> \
</div>';

conways game of life from automate boring stuff book
|
<p>i need to create a python conways game of life. i have this code given below from book "how to automate boring stuff with python" i had run this code but the output doesn't seem that the code is correct. i intended to get a result of the conway program to be in grid. can you please review the code and briefly decode it for me.</p>
<pre><code> # Conway's Game of Life
import random, time, copy
WIDTH = 60
HEIGHT = 20

nextCells = []
for x in range(WIDTH):

for y in range(HEIGHT):
if random.randint(0, 1) == 0:
column.append('#') # Add a living cell.
else:
column.append(' ') # Add a dead cell.
nextCells.append(column) # nextCells is a list of column lists.
while True: # Main program loop.
print('\n\n\n\n\n') # Separate each step with newlines.
currentCells = copy.deepcopy(nextCells)
# Print currentCells on the screen:
for y in range(HEIGHT):
for x in range(WIDTH):
print(currentCells[x][y], end='') # Print the # or space.
print() # Print a newline at the end of the row.
# Calculate the next step's cells based on current step's cells:

Data exists, but the map function returns no value React Native

<p>I guess I'm not realizing something. I have the structure where I list the friends of the logged in user. Data appears to exist on console.log, but the map function does not work.

TensorFlow batch tensors with different shapes
|
<p>I am studying Neural Network and I have encountered what is probably a silly problem which I can't figure out. For my first ever network, I have to create a flower image classifier in Keras and TensorFlow using the <a href="https://www.tensorflow.org/datasets/catalog/oxford_flowers102" rel="nofollow noreferrer">oxford_flowers102</a> and the MobileNet pre-trained model from TensorFlow Hub.</p>
<p>The issue seems to be that the images are not re-sized to (224,224,3), but they keep their original shapes which are different from one and other. However, according to my class material, my re-sizing code is correct so I don't understand what is going on and what I am doing wrong.</p>
<p>Thank you very much for all your help.</p>
<pre><code># LOADING

How to I make my php include stay at the bottom?
|
<p>So I've been editing my website and recently tried to upload the basics (index, css and some other pages) but when I have looked at one of the pages, the actual article overlaps the bottom div and I don't know how its done that.</p>
<p>Here is the css for the bottom:</p>
<pre><code>div#bottom {
background-color: #2C292B;
width: 100%;
height: 120px;
color: #888888;
padding-top: 40px;
padding-bottom: 40px;
}
div#copyright {
background-color: #1F1D1E;
width: 100%;
height: 45px;
font-weight: bold;
}
</code></pre>
<p>And here is the code for the index: </p>
<pre><code><script type="text/javascript">
if (location.pathname.substr(0, 3) !== "/m/" && screen.width <= 720) {
location.href = "/m" + location.pathname;
}

MongoDB View vs Function to abstract query and variable/parameter passed
|
<p>I hate to risk asking a duplicate question, but perhaps this is different from <a href="https://stackoverflow.com/questions/52786830/passing-variables-to-a-mongodb-view">Passing Variables to a MongoDB View</a> which didn't have any clear solution.</p>
<p>Below is a query to find the country for IP Address 16778237. (Outside the scope of this query, there is a formula that turns an IPV4 address into a number.)</p>
<p>I was wondering if we could abstract away this query out of NodeJS code, and make a view, so the view could be called from NodeJS. But the fields ipFrom and ipTo are indexed to get the query to run fast against millions of documents in the collection, so we can't return all the rows to NodeJS and filter there.</p>
<p>In MSSQL maybe this would have to be a stored procedure, instead of a view. Just trying to learn what is possible in MongoDB. I know there are functions, which are written in JavaScript. Is that where I need to look?</p>
<pre><code>db['ip2Locations'].aggregate(
{
$match:
{
$and: [
{
"ipFrom": {
$lte: 16778237
}
},
{
"ipTo": {
$gte: 16778237
}
},
{
"active": true
}
],
$comment: "where 16778237 between startIPRange and stopIPRange and the row is 'Active',sort by createdDateTime, limit to the top 1 row, and return the country"
}
},
{
$sort:
{
'createdDateTime': - 1
}
},
{
$project:
{
'countryCode': 1
}
},
{
$limit: 1
}
)
</code></pre>
<p>Part 2 - after more research and experimenting, I found this is possible and runs with success, but then see trying to make a view below this query.</p>
<pre><code>var ipaddr = 16778237
db['ip2Locations'].aggregate(
{
$match:
{
$and: [
{
"ipFrom": {
$lte: ipaddr
}
},
{
"ipTo": {
$gte: ipaddr
}
},
{
"active": true
}
],
$comment: "where 16778237 between startIPRange and stopIPRange and the row is 'Active',sort by createdDateTime, limit to the top 1 row, and return the country"
}
},
{
$sort:
{
'createdDateTime': - 1
}
},
{
$project:
{
'countryCode': 1
}
},
{
$limit: 1
}
)
</code></pre>
<p>If I try to create a view with a "var" in it, like this;</p>
<p>db.createView("ip2Locations_vw-lookupcountryfromip","ip2Locations",[
var ipaddr = 16778237
db['ip2Locations'].aggregate(</p>
<p>I get error:</p>
<pre><code>[Error] SyntaxError: expected expression, got keyword 'var'
</code></pre>
<p>In the link I provided above, I think the guy was trying to figure how the $$user-variables work (no example here: <a href="https://docs.mongodb.com/manual/reference/aggregation-variables/" rel="nofollow noreferrer">https://docs.mongodb.com/manual/reference/aggregation-variables/</a>). That page refers to $let, but never shows how the two work together. I found one example here: <a href="https://www.tutorialspoint.com/mongodb-query-to-set-user-defined-variable-into-query" rel="nofollow noreferrer">https://www.tutorialspoint.com/mongodb-query-to-set-user-defined-variable-into-query</a> on variables, but not $$variables. I'm</p>
<p>db.createView("ip2Locations_vw-lookupcountryfromip","ip2Locations",[
db['ip2Locations'].aggregate(
...etc...
"ipFrom": {
$lte: $$ipaddr
}</p>
<p>I tried ipaddr, $ipaddr, and $$ipaddr, and they all give a variation of this error:</p>
<pre><code>[Error] ReferenceError: $ipaddr is not defined
</code></pre>
<p>In a perfect world, one would be able to do something like:</p>
<pre><code> get['ip2Locations_vw-lookupcountryfromip'].find({$let: {'ipaddr': 16778237})
</code></pre>
<p>or similar.</p>
<p>I'm getting that it's possible with Javascript stored in MongoDB (<a href="https://stackoverflow.com/questions/48136206/how-to-use-variables-in-mongodb-query">How to use variables in MongoDB query?</a>), but I'll have to re-read that; seems like some blogs were warning against it.</p>
<p>I have yet to find a working example using $$user-variables, still looking.</p>

JQueryUI datepicker is not setting/posting the value of the textbox after a date is selected
|
<p>The textbox starts with a value of 1/1/0001, which I am assuming is the default starting date for a new datetime. The issue is that after a date is selected from the datepicker menu, the value on the HTML element is never changed and 1/1/0001 gets posted to the controller after the form is submitted. The text within the textbox is changed, but when using the browser dev tools the value is still 1/1/0001.</p>
<p><strong>HTML</strong></p>
<pre><code><div class="row col-12 formdatepicker">
<input asp-for="StartDate" type="text" class="form-control" id="startdatepicker" />
<span style="margin-left: 8px; margin-right: 8px; padding-top: 5px;">to</span>
<input asp-for="EndDate" type="text" class="form-control" id="enddatepicker" />
</div>
</code></pre>
<p><strong>JS</strong></p>
<pre><code>$(document).ready(function () {
$("#startdatepicker").datepicker({
onSelect: function () {
alert($('#startdatepicker').val());
}
});
$("#enddatepicker").datepicker();
var data = $('form').serialize();
var dataType = 'application/x-www-form-urlencoded; charset=utf-8';
$(function () {
$('#submit').on('click', function (evt) {
console.log('Submitting form...');
console.log(data);
evt.preventDefault();
//Ajax form post
$.ajax({
type: 'POST',
data: data,
contentType: dataType,
url: '@Url.Action("Daily","Reports")',
success: function (data) {
if (data.success) {
alert("Data Success");
} else {
console.log(data);
//Toggle the error modal and display error messages
$('#errorsModal').modal('toggle');
//Add <br> tags when there is a linebreak in the string. This will add the line breaks into the HTML.
$('#errorsModal .modal-body p').html(data.message.replace(/(?:\r\n|\r|\n)/g, '<br>'));
}
}
});
});
});
});
</code></pre>
<p>The <code>.datepicker()</code> initializations are working correctly because the datepicker menu's are appearing when the textbox is clicked. The onSelect alert never appears though when the value is changed. </p>

Convert array of types to union of object type
|
<p>Let's say I have these types:</p>
<pre class="lang-js prettyprint-override"><code>type StepA = // ...
type StepB = // ...
type StepC = // ...
type Steps = [StepA, StepB, StepC]
</code></pre>
<p>I want to have an utility type <code>SomeUtilityType<T></code> so that:</p>
<pre class="lang-js prettyprint-override"><code>type StepsCombinations = SomeUtilityType<Steps>
// type StepsCombinations =
// | { step: 0; value: StepA }
// | { step: 1; value: StepB }
// | { step: 2; value: StepC };
</code></pre>
<p>How should I define <code>SomeUtilityType<T></code>?</p>
<p><strong>Edit</strong></p>
<p>If <code>Steps</code> is defined as an object</p>
<pre class="lang-js prettyprint-override"><code>type Steps = {0: StepA, 1: StepB, 2: StepC}
</code></pre>
<p>this utility using <a href="https://www.typescriptlang.org/docs/handbook/2/conditional-types.html#distributive-conditional-types" rel="nofollow noreferrer">Distributive Conditional Types</a> would do the trick (see <a href="https://www.typescriptlang.org/play?#code/C4TwDgpgBAysFgIJQLxQERwY9AoUks8YAQqhlmAMJ4HSVXmbEl77j3EDO5A2pYgA0RBCWEMAurnaFKXAPIAjAFYQAxsHIBvAAwAuEUmEBGA5TFQATGeJUAvtLqwA9gFsIAVWABLADbfQABUOAB5cKCgANSgIAA94ADsAEx4tKF5vZLiDBIBXV0UIACcJA1yEgGsE5wB3BKg7QXCoQJj4iGSeCogQZwAzKPJu3oHI3AA+cla4xJSocqrahOaAfig0rmIDQIBuKAA3AENfXIgDSN5AiT2HCJyIfeKdxw5DLio3RUzDn2cEnjQMDcnh8-iCoTkSlUGnGQA" rel="nofollow noreferrer">playground</a>):</p>

V extends { [index: number]: unknown },
T extends keyof V = keyof V

: never;
</code></pre>
<p>But I would much prefer avoid defining an object with superfluous keys <code>0, 1 , 2...</code>.</p>
<p>I think I could use the above type definition of <code>SomeUtilityType</code> if there were some way to get an union of all indexes in the array, like <code>Indexes<Steps> // --> 0 | 1 | 2</code></p>

C# WPF App silently crashes if I use "open with"
|
<p>I am making a text editor in C# WPF. After publishing the project to a folder, I can double-click the .exe, it runs fine, and I can load files using my Open (CTRL+O) function perfectly fine.</p>
<p>I want to use <strong>Open with > Choose another app > More apps > Look for another app on this PC</strong>
(I'm not worrying about file associations yet - during development this is fine)</p>
<p>Here's the problem - no matter what I do to my code, I can't get my app to do anything useful when I use this method to open it. What happens is it brings up a randomly sized white window and looks like it's busy - after 2 seconds it closes itself. The name of the window is "%PathOfTheFileIOpened% - KuroNote", which seems to be automatic.</p>
<p><em>App.xaml</em></p>
<pre><code><Application x:Class="KuroNote.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:KuroNote"
Startup="Application_Startup"
ShutdownMode="OnMainWindowClose">
<Application.Resources>
</Application.Resources>
</Application>
</code></pre>
<p><em>App.xaml.cs</em></p>
<pre><code>namespace KuroNote
{
/// <summary>
/// Interaction logic for App.xaml
/// </summary>
public partial class App : Application
{
private void Application_Startup(object sender, StartupEventArgs e)
{
MessageBox.Show("test");
foreach (string s in e.Args)
{
MessageBox.Show(s);
}
}
}
}
</code></pre>
<p>As you can see, I removed all the useful code to try and get it to do SOMETHING - I'm not even opening the main window, I just want it to output its command line arguments. When I use the "Look for another app on this PC" method, I don't even get the "test" message box, like you see is written above.</p>
<p>As you can see from <a href="https://i.stack.imgur.com/Ailkx.png" rel="nofollow noreferrer">this screenshot of the project properties,</a> the startup object is also set to be the app.</p>
<hr />
<p>I thought it might be permissions-related, but the executable and the file to be opened are never in protected administrator-only areas.</p>
<p>I've done tests before while debugging, retrieving command line arguments set in project properties > debug tab > "application arguments:", and those are returned just fine. Something seems to be different about opening using the "Look for another app on this PC" method, it's like it's doing more than just launching the app with a command line argument with the filepath.</p>
<p>Am I missing some kind of flag in App.xaml that enables "Open with" functionality?</p>
<hr />
<p>It's a purely offline application, not a web app, and the files I get after publishing are just "KuroNote.deps.json", "KuroNote.dll", "KuroNote.exe", "KuroNote.pdb" and "KuroNote.runtimeconfig.json", no ".application" files that it sounds like "ClickOnce" uses. If I search for "ClickOnce" inside visual studio, it says I can install it, but it doesn't sound like it's already installed. Unless there's some hidden "use ClickOnce" setting that I need to disable?</p>

<p>If I use strip.white within the read.csv call, the white spaces are removed. I'm assuming this has something to do with how read.csv works, but looking through the appropriate <a href="http://stat.ethz.ch/R-manual/R-devel/library/utils/html/read.table.html" rel="nofollow noreferrer">R documentation</a> I still don't understand why this is occurring. </p>
<pre><code>returns <-read.csv("~/R/ADFG_Obtained_AKReturns.csv", stringsAsFactors = FALSE, strip.white = TRUE)

<p>So adding the strip.white call does exactly what I would like for the blank ("-") cells, I just don't understand why; and why does trimws not work in this case? </p>
<p>Also, are there still whitespaces remaining on the observations that are numbers? </p>
<pre><code>$ Seine : chr "-" "-" "-" " 2,000 " ...
</code></pre>
<p>For my next step, I will be changing the type from character to numeric with the following code, but would appreciate any suggestions on how to do this for all columns Seine:Other (cols 6:15 in my df). </p>
<pre><code>returns$Seine <- as.numeric(gsub(",","",returns$Seine))
$ Seine : num NA NA NA 2000 NA NA NA NA NA NA ...

How to clear Select Box old Data & Fill with new Data on Selection Javascript?

<p>I have 2 drop downs, this thing here is when user select BMW i want to fill data 1,2,3,4,5 & when he selects Volvo i want to display 5,6,7,8,9. Data is getting populated in second drop down but i can see old data as well & as many times i click the list is getting increased.

Unable to create Generic CustomAttributeData properly when using programatically generated Enum
|
<p>I am trying to source a PropertyGrid with a dynamically generated object.</p>
<p>For combo selections on this property grid, I have built a TypeConverter (where T is an enum, defining the list of options):</p>
<pre><code> public class TypedConverter<T> : StringConverter where T : struct, IConvertible
{
...
public override System.ComponentModel.TypeConverter.StandardValuesCollection
GetStandardValues(ITypeDescriptorContext context)
{
if (!typeof(T).IsEnum) throw new ArgumentException("T must be an enumerated type");
string[] values = Enum.GetValues(typeof(T)).OfType<object>().Select(o => o.ToString()).ToArray();
return new StandardValuesCollection(values);
}
}
</code></pre>
<p>I can then add a custom attribute to the property, referencing this TypeConverter, as below (typedConverterGenericType is the the type of TypedConverter with an enum generic argument)</p>
<pre><code>CustomAttributeBuilder attributeBuilder = new CustomAttributeBuilder(typeof(TypeConverterAttribute).GetConstructor(new Type[] { typeof(Type) }), new Type[] { typedConverterGenericType });
propertyBuilder.SetCustomAttribute(attributeBuilder);
</code></pre>
<p>This works <strong>great</strong>, as long as the Enum in question is hardcoded: <code>AddTypeConverterAttribute(propertyBuilder, typeof(TypedConverter<Fred>));</code>. In the debugger, the attribute on the property gives me <code>{[System.ComponentModel.TypeConverterAttribute( ...</code>.</p>
<p>However, when I use a dynamically built enum (that I have determined is generated properly in reflection) does not work:</p>
<pre><code> Type enumType = enumBuilder.CreateType();//This generates a proper enum, as I have determined in reflection
Type converterType = typeof(TypedConverter<>);
Type typedConverterType = converterType.MakeGenericType(enumType);
AddTypeConverterAttribute(propertyBuilder, typedConverterType);
</code></pre>
<p>In the debugger, the attribute on the property now gives me <code>{System.Reflection.CustomAttributeData}</code>, and drilling into this, I have an error on the ConstructorArguments <code>... Mscorlib_CollectionDebugView<System.Reflection.CustomAttributeData>(type.GetProperties()[1].CustomAttributes).Items[4].ConstructorArguments' threw an exception of type 'System.IO.FileNotFoundException'</code> </p>
<p>What am I doing wrong? How can I get the TypeConverter attribute set properly?</p>
<p><strong>EDIT</strong>: In case someone wants to see how I add the attribute</p>
<pre><code>private void AddTypeConverterAttribute(PropertyBuilder propertyBuilder, Type typedConverterGenericType)
{
CustomAttributeBuilder attributeBuilder = new CustomAttributeBuilder(typeof(TypeConverterAttribute).GetConstructor(new Type[] { typeof(Type) }), new Type[] { typedConverterGenericType });
propertyBuilder.SetCustomAttribute(attributeBuilder);
}
</code></pre>
<p><strong>EDIT2</strong></p>
<p>Testing confirms it is an issue with the dynamically built enum - if I create the generic type with <code>Type typedConverterType = converterType.MakeGenericType(typeof(Fred));</code> it works fine.</p>
<p><strong>EDIT 3</strong></p>
<p>My test project is available <a href="http://purehumbug.com/files/PropertiesExample.zip" rel="nofollow">here</a>. It is reading some JSON from Resouces, and trying to generate a class whose type is described by that JSON. </p>
<p>I am creating an instance of that class (<code>Activator.CreateInstance</code>) that will source a PropertyGrid. To get combo selection on that PropertyGrid, I am creating a Type, with a property attributed with TypedConverter, where T is an enum that describes the values in the combo selection. </p>
<p>This works great for hardcoded enums, but not for programatically generated ones</p>

Python multithreading - writing to file is 10x slower
|
<p>I've been trying to convert a large file with many lines (27 billion) to JSON. Google Compute recommends that I take advantage of multithreading to improve write times. I've converted my code from this:</p>
<pre><code>import json
import progressbar
f = open('output.txt', 'r')
r = open('json.txt', 'w')
import math
num_permutations = (math.factorial(124)/math.factorial((124-5)))
main_bar = progressbar.ProgressBar(maxval=num_permutations, \
widgets=[progressbar.Bar('=', '[', ']'), ' ', progressbar.Percentage(), progressbar.AdaptiveETA()])
main_bar.start()
m = 0
for lines in f:
x = lines[:-1].split(' ')
x = json.dumps(x)
x += '\n'
r.write(x)
m += 1
main_bar.update(m)
</code></pre>
<p>to this:</p>
<pre><code>import json
import progressbar
from Queue import Queue
import threading
q = Queue(maxsize=5)
def worker():
while True:
task = q.get()
r.write(task)
q.task_done()
for i in range(4):
t = threading.Thread(target=worker)
t.daemon = True
t.start()
f = open('output.txt', 'r')
r = open('teams.txt', 'w')
import math
num_permutations = (math.factorial(124)/math.factorial((124-5)))
main_bar = progressbar.ProgressBar(maxval=num_permutations, \
widgets=[progressbar.Bar('=', '[', ']'), ' ', progressbar.Percentage(), progressbar.AdaptiveETA()])
main_bar.start()
m = 0
for lines in f:
x = lines[:-1].split(' ')
x = json.dumps(x)
x += '\n'
q.put(x)
m += 1
main_bar.update(m)
</code></pre>
<p>I've copied the Queue coding pretty much straight from the module manual.</p>
<p>Before, the whole script would take 2 days. Now it is saying 20 days! I'm not quite sure why, could anyone explain this to me?</p>
<p><strong>EDIT:</strong> This could be considered a Python Global Interpreter Lock (GIL) problem, however, I don't think it is so - it is not computationally intensive and is an IO bottleneck problem, from the threading docs:</p>
<blockquote>
<p>If you want your application to make better use of the computational
resources of multi-core machines, you are advised to use
multiprocessing. However, threading is still an appropriate model if
you want to run multiple I/O-bound tasks simultaneously.</p>
</blockquote>
<p>My understanding of this is limited, but I believe this to be the latter, ie. an IO bound task. This was my original thought when I wanted to go for multi-threading in the first place: That the computation was being blocked by IO calls that could be put to a separate thread to allow the computation functions to continue.</p>
<p><strong>FURTHER EDIT:</strong> Perhaps the fact is that I've got an IO block from the INPUT, and that is what is slowing it down. Any ideas on how I could effectively send the 'for' loop to a separate thread? Thanks!</p>

jquery duplicating dynamically created content
|
<p>im building a phone app using html5, jquery and php and database. I have a messaging system im trying to develope and have an issue with jquery dynamically creating buttons. I have code that creates a message subject div and message content div using details from the database called using ajax and json, I have then created a delete message button that should get the messageid that will allow the user to delete message from the database once read. The present issue is in dynamic creation of the delete button jquery is duplicating the button, so i need to get jquery to just create the button with the id of the message only, then use a jquery ajax function to delete the message.

jQuery Ajax load table not whole page
|
<h1>FIXED</h1>
<p>My problem is resolved. My issue was not the jQuery command as much as i was using the same template as when first loading the page and the table included in that jsp page. </p>
<h2>Solution</h2>
<p>MY solution:
Create a new template to be called on new page load name ControlTable.
Create a new jsp file with only the table. Have it loaded with both templates.
when jquery is triggered call only the new template via the controller -> template -> jstl core </p>
<p><strong>Background</strong></p>
<ol>
<li>I have a form that I fill in to create a website user login information. </li>
<li>When i enter the text into 'plantNo' and select producer from my Drop Down list. i want it to load a table into after querying the servlet to get the data. </li>
<li>It is getting the data ( i can see via console) and retrieving the list. </li>
</ol>
<p><strong>Problem</strong></p>
<p>The problem is the reloading of the table. It is reloading the whole webpage into the table. What am i doing wrong? I am new to jQuery and AJAX.</p>
<p><strong>jQuery function</strong></p>
<pre><code>function getProdInfoData(variableIn){
var plantnumber=document.myform.plantNo.value.trim();
alert(plantnumber);
$.post('Admin?page=createUser', {"plant_no": plantnumber },function(data){
$('#pi').html(data).hide().slideDown('slow');

<p>Edit: Figured out a solution. As mentioned, the radzen syntax in the example is very specific and albeit hidden it does require an extra template before or after the outter datagrid for it to work. This example works:</p>

Android Signed Apk crashed in below 5.0 Versions

<p>I create a signed APK and upload that, it crashes in all below version of marshmallow. The signed APK works on Android above version 5.0, but not on <5.0. The AppCompat Library is linked with the project in Android.</p>
<p>And when I normally run the same project in android 5.0 it work perfectly but signed apk not run in 5.0.</p>
<p>And it was also not generating the crash report.</p>

Sorting attachments into different folders
|
<p>I updated a (working) macro which I received from my friend (this macro sorts attachments into different folders) The update relates to select - case block in SaveAttachment Procedure. I'd like to save attachments into 2 different paths - PATH and PATH2 depending on the folder. For TargetFolderItemsAA and TargetFolderItemsAB there will be PATH2 and for the rest - PATH. Does anybody know, what's wrong with the code (an error occurs)? Thanks for your help in advance.</p>

Resource allocation algorithm for an airlock on a moon base
|
<p>I'm trying to find an algorithm or problem name on a resource allocation problem that goes something like this.</p>
<p>A moon base has an airlock that only one person can use at a time, either to enter or exit, and takes 20 seconds to pass through. Airlock transitions cannot be aborted early or reversed. Astronauts have a limited amount of air when they are outside the base (say 10 minutes). Their job on the moon is to operate a number of drills that are different distances from the moon base, and keep them running with 100% manned uptime.</p>
<p>I hope to answer questions like these:
How many drill sites can be supported with no astronauts running out of air? How do you determine the schedule for the airlock (who gets to enter/exit and in what order)?</p>
<p>There are 2 components:<br>
- First figuring out the number of astronauts required to man each drill site with 100% up time.<br>
- Figuring out the number of drills that can be operated using one airlock</p>
<pre><code>Per Drill:
MaxWorkTime[i] = AirTime - 2*TravelTime[i]
ActualWorkTime[i] < MaxWorkTime[i]
WorkersPerDrill[i] = AirTime/ActualWorkTime[i]
for each drill
try to schedule airlock time
</code></pre>
<p>WorkTime can be reduced to schedule workers more optimally on the airlock as it approaches 100% utilization (I think).</p>
<p>Below is a simple diagram to try to clarify the problem more. The airlock time is consumed by astronauts using it and is indicated by the bars. I want to increase usage to its maximum while not sending too many astronauts outside. The astronauts work cycle is shown for one drill. The astronaut uses airlock time to exit, walks to the worksite, works, walks back to base, and uses airlock to enter.</p>
<pre><code> |---time-->
Airlock: |--x---| |--x---| |--x---| |--x---|
Astronaut1 |-lock-|--to--|---------drill1--------|-from-|-lock-|
Astronaut2 |-lock-|--to--|-------drill1--------|-from-|-lock-|
^
drill1 always manned
</code></pre>
<h2>Update (Example with numbers)</h2>
<pre><code>AirTime = 10min
WalkSpeed = 1 m/s
drill[0] = 180m // 6min to/from travel
drill[1] = 150m // 5min
drill[2] = 120m // 4min
drill[3] = 240m // 8min
TravelTime[0] = 6min
...
MaxWorkTime[0] = AirTime - TravelTime[0] = 4min
...
// WorkersPerDrill = AirTime/MaxWorkTime
WorkersPerDrill[0] >= 2.5 // These numbers are over 1 airtime (10m)
WorkersPerDrill[1] >= 2
WorkersPerDrill[2] >= 1.67
WorkersPerDrill[3] >= 5
TotalWorkersPerAirtime = sum(WorkersPerDrill) = 11.17
AirlockTime = 20s
AirlockPerWorker = 40s
TotalAirlockUsage = TotalWorkersPerAirtime*AirlockPerWorker = 7.4 min of airlock time
74% usage of airlock if no one uses it at the same time
</code></pre>
<p>This is the first part of the problem. Once there is a conflict where drill[1] worker and drill[3] worker come back at the same time there is a chance one runs out of air. That is the problem I'm trying to solve. Thanks for putting up with this long winded question!</p>

What do these networkx errors mean which I am getting after setting a filter on my pandas dataframe?
|
<p>I have a source, target and weight dataframe called <code>Gr_Team</code> which looks like this (sample) -</p>
<pre><code>Passer Receiver count
116643 102747 27
102826 169102 10
116643 102826 7
167449 102826 8
102747 167449 4
</code></pre>
<p>Each Passer and Receiver have their unique x,y co-ordinates which I have in a dictionary <code>loc</code> - <code>{'102739': [32.733999999999995, 26.534], '102747': [81.25847826086964, 27.686739130434784], '102826': [68.09609195402302, 77.52206896551728]}</code>
I plotted this using networkx:</p>
<pre><code>G=nx.from_pandas_edgelist(Gr_Team, 'Passer', 'Receiver', create_using=nx.DiGraph())
nx.draw(G, loc, with_labels=False, node_color='red',
node_size=Gr_Team['count']*100,
width=Gr_Team['count'],
edge_color = Gr_Team["count"],
edge_cmap = cmap,
arrowstyle='->',
arrowsize=10,
vmin=vmin,
vmax=vmax,
font_size=10,
font_weight="bold",
connectionstyle='arc3, rad=0.1')
</code></pre>
<p>That worked without any issues and here's what I got:
<a href="https://i.stack.imgur.com/jawQJ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/jawQJ.png" alt="enter image description here"></a></p>
<p>However, as soon as I try to filter out all the rows with count value below a constant, let's say 3, using this <code>Gr_Team = Gr_Team[Gr_Team["count"]>3]</code>, I get a key error and here's the entire error and traceback which I can't make anything out of: </p>

KeyError: 1
</code></pre>
<p>I realized that doing only <code>nx.draw(G, loc, with_labels=False, node_color='red')</code> still worked but as soon as I try to pass <code>node_size</code> or <code>edge_color</code>, it hits the above error. From my understanding, the error is only when I'm using the dataframe <code>Gr_Team</code> in the keyword arguments. </p>
<p>I can't figure out why that's happening and why filtering breaks the code. Any help would be appreciated.</p>
<p><strong>EDIT 1</strong>: <a href="https://gist.github.com/AbhishekSharma99/446116421e8e97fe2dcacb8a0f96a38c" rel="nofollow noreferrer">Here</a>'s a gist of the entire code. I tried my best to keep it minimal. <a href="https://github.com/AbhishekSharma99/Opta-Data-Feed/blob/master/PSGCopy_NancyLyonAllEvents.csv" rel="nofollow noreferrer">Here</a>'s the link to the csv file that needs to be read in as df. The line which produces the error is in also in there; commented out.</p>
