Simulate data in JAGS/r2jags | <p>Is it possible to misuse JAGS as a tool for generating data from a model with known parameters? I need to sample data points from a predefined model in order to do a simulation study and test the power of a model I have developed in R.</p>
<p>Unfortunately, the model is somehow tricky (hierarchical structure with AR and VAR component) and I was not able to simulate the data directly in R.
While searching the internet, I found a <a href="http://www.georg-hosoya.de/wordpress/?p=799" rel="nofollow">blog post</a> where the data was generated in JAGS using the <code>data{}</code> Block in JAGS. In the post, the author than estimated the model directly in JAGS. Since I have my model in R, I would like to transfer the data back to R without a <code>model{}</code> block. Is this possible?</p>

WPF: binding to dependency property of a class that inherits a user control base class | <p>I have a user control in wpf named "GoogleMap.xaml/.cs" where the xaml declaration starts like this:</p>
<pre><code><controls:BaseUserControl x:Class="CompanyNamespace.Controls.GoogleMap"
</code></pre>
<p>the code behind:</p>
<pre><code> public partial class GoogleMap : BaseUserControl{
public static readonly DependencyProperty MapCenterProperty =
DependencyProperty.Register("MapCenter", typeof(string), typeof(GoogleMap), new FrameworkPropertyMetadata(string.Empty, OnMapCenterPropertyChanged));
public string MapCenter {
get { return (string)GetValue(MapCenterProperty); }
set { SetValue(MapCenterProperty, value); }
}
private static void OnMapCenterPropertyChanged(DependencyObject source, DependencyPropertyChangedEventArgs e){
GoogleMap control = source as GoogleMap;
control.SetCenter(e.NewValue.ToString());
}
...
}
</code></pre>
<p>What's the correct syntax for me to be able to address the property from GoogleMap.xaml:</p>
<pre><code>MapCenter="{Binding Location}"
</code></pre>
<p>I can only bind to this property from GoogleMap.xaml if I place the property is in the BaseUserControl class. </p>
<p><strong>Update</strong>
GoogleMapViewModel.cs</p>
<pre><code>public class GoogleMapViewModel : ContainerViewModel{
private string location;
[XmlAttribute("location")]
public string Location {
get {
if (string.IsNullOrEmpty(location))
return appContext.DeviceGeolocation.Location();
return ExpressionEvaluator.Evaluate(location);
}
set {
if (location == value)
return;
location = value;
RaisePropertyChanged("Location");

What exactly are LDFLAGS and CXXFLAGS? | <p>I have read for some installation, I need to set up environment variables LDFLAGS, LD_LIBRARY_PATHS and CXXFLAGS correctly for ./compile.sh to run. However, I am not sure what path to give there. Can someone please explain what those flags mean and what are they used for? Are they something related to the gcc installation? </p>
<p>I am working on CENTOS 6.6 with default gcc 4.4.7 but I want to use gcc 4.9.1 which is installed in /opt/rh/devtoolset-3/root/usr/bin/gcc.</p>
<p>I tried to look up other similar questions but did not get my answer. i want to know what exactly the paths/flags mean.</p>
<p>I am new to Linux so please disregard my ignorance. Thank you.</p> | 2 |
Setting width of iconContainer of StepperButton in react material-ui | <p>I'm using the callemall react material-ui Stepper component to good effect but there's one thing I can't seem to do:
Within a Stepper you have Steps. Those Steps have StepButtons which can have an icon. The icon is within a span that gets the style: styles.iconContainer. </p>
<p>Unfortunately the width there is hardcoded to 24px which is a problem if you want to have bigger icons. Try as I might I'm not able to override the width of said container. </p>
<p>This leads to the following situation, I have a button with an Icon (bigger than normal) and some text underneath it. This works fine but the Icon doesn't get centered as the span containing it is too small.</p>
<p>Looks like this (look at the second and third Icon, they are not centered):
<a href="https://i.stack.imgur.com/cmK2y.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/cmK2y.png" alt="uncentered"></a></p>
<p>If I change the hardcoded width of 24px to 100% it looks like this (much better):
<a href="https://i.stack.imgur.com/wwxdg.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/wwxdg.png" alt="centered"></a></p>
<p>Unfortunately I can only achieve this if I change the code of the StepLabel component itself, something I don't want to do. The code that prepares the style looks like this:</p>
<pre><code>var styles = {
root: {
height: orientation === 'horizontal' ? 72 : 64,
color: textColor,
display: 'flex',
alignItems: 'center',
fontSize: 14,
paddingLeft: 14,
paddingRight: 14
},
icon: {
color: iconColor,
display: 'block',
fontSize: 24,
width: 24,
height: 24
},
iconContainer: {
display: 'flex',
alignItems: 'center',
paddingRight: 8,
width: 24 -->this hardcoded thing is giving me headaches
}
</code></pre>
<p>};</p>
<p>So, does anyone have a suggestion on how I could override this specific style?</p>
<p>Source for the StepLabel Component can be found at: <a href="https://github.com/callemall/material-ui/blob/master/src/Stepper/StepLabel.js" rel="nofollow noreferrer">GitHub | StepLabel</a> if you need to see it within context.</p> | 2 |
(Polymer) Refreshing google-map after dynamically adding google-map-markers to DOM | <p>Currently using the google-map component for Polymer and having some issues. </p>
<p><a href="https://elements.polymer-project.org/elements/google-map" rel="nofollow">https://elements.polymer-project.org/elements/google-map</a></p>
<p>What I'm wanting to do is dynamically create google-map-markers to display on a map. This could be coordinates in the URL, data grabbed from our database, etc.</p>
<p>This is what my code currently looks like below: </p>
<pre><code><google-map id="map" fit-to-markers api-key="API-KEY">
<template is="dom-repeat" items="{{data}}">
<google-map-marker latitude="[[item.Latitude]]" longitude="[[item.Longitude]]">Marker</google-map-marker>
</template>
</google-map>
</code></pre>
<p>Here's my issue, however. This ONLY works whenever the markers finish rendering to the DOM before the map is loaded. If the map loads first, the markers will not show up. So obviously, I'm hitting a race condition. </p>
<p>Is there any way to refresh the google-map element to display the new markers after they've finished rendering to the DOM? I feel like I've tried every function on the element's page to no avail.</p>
<p>Any help would be greatly appreciated.</p> | 2 |
C# winforms best place where to check if user logged | <p>Guys in my winforms desktop application i have user logging system. Am not sure where to set logic to check if user is logged or not. If is logged show main window or if not logged show login form.</p>
<p>First i try to avoid using database for logging because winforms does not support sessions. I crate static <code>User</code> class where i store super_admin credentials and that is enough for this app.</p>
<p>So my first try is to set everything in main before mainWindow form is showed:</p>
<p><strong>Program.cs</strong></p>
<pre><code>[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
if (!User.IsLogged)
{
Application.Run(new Login());
}
Application.Run(new Login());
}
</code></pre>
<p>Or is better to set this inside <code>MainWindow</code> form inside constructor or in <code>Load</code>? Or Maybe inside static <code>MainWindow</code> constuctor? MainWindow is mdi! </p>
<p>So can you suggest me what is better way?</p>
<p>Here is static (User.cs):</p>
<pre><code>private static string superAdminUsername = "admin";
private static string superAdminPassword = "123";
public static bool IsLogged
{
get
{
return isLogged;
}
set
{
isLogged = value;
}
}
public static bool Authenticate(string username, string password)
{
if (username == superAdminUsername && password == superAdminPassword)
{
isLogged = true;
return true;
}
return false;
}

train a language model using Google Ngrams | <p>I want to find a conditional probability of a word given its previous set of words. I plan to use <code>Google N-grams</code> for the same. However, being such a huge resource as it is, I don't think it is computationally possible to do on my PC. ( To process all N-grams, to train a language model). </p>
<p>So is there any way I can train a language model using Google Ngrams ? (Even <code>python NLTK</code> library does not support <code>ngram</code> language model anymore)
Note - I know that a language model can be trained using ngrams, but given the vast size of Google N grams, how can a language model be trained using specifically Google ngrams?</p> | 2 |
Sending on behalf of users with Amazon SES | <p>Sometimes it's necessary to send an email with the reply-to address of another user. For example, if a LinkedIn user sends a connection of theirs a LinkedIn message, it makes sense to send that email from the user that sent the message, so that clicking 'reply' actually replies to the person who sent the message. </p>
<p>Is there a way to do this with Amazon SES? </p> | 2 |

<p>Does anyone know why this happens? I contacted Firebase support and they couldn't help. </p>
<p>Knowing that this is an app that was working fine before switching to Firebase, I know that push configurations on the app side are working. And considering that all the configuration on the Firebase Console was imported from my previous Google Project, I know that my certificates are all working as well (they are the same certificates).</p>
<p>In an attempt to check whether my app code was the problem, I ran the sample app (<a href="https://github.com/firebase/quickstart-ios/tree/master/messaging/FCMSwift" rel="nofollow">https://github.com/firebase/quickstart-ios/tree/master/messaging/FCMSwift</a>), changing the Bundle Identifier and using my project's GoogleService-info.plist file and the result is the same 501 error, which leaves me no doubt that the problem is not with the app code.</p>
<p>Does anyone have any clue how to solve this?</p> | 2 |

Re-render child component when back button is clicked | <p>Im wondering if there is any straightforward way to get a single child component to rerender when the back button is clicked. For example:</p>

<child-two />
</parent>

<p><code>componentWillReceiveProps</code> is hit whenever the back button is clicked.</p>
<p>Any ideas? I don't want to re-render the entire parent component.</p> | 2 |

Truncating float to the two first non-zero decimal digits | <p>I want to truncate floating point numbers in Java up to the two first non-zero decimal digits. For example, <code>0.000134</code> to <code>0.00013</code>, or <code>11.00401</code> to <code>11.0040</code>.</p>
<p>The only solution I can think of is to strip the integral part, and multiply by 10 until I get a number bigger or equal to 10. Then truncate the original float up to <code>number of multiplications</code> decimal digits.</p>
<p>But I might have to do this operation often, so I'm looking for a faster solution.</p>
<p>My test code:</p>
<pre><code>public static String truncateTo2NonZero(double f) {
int integral = (int)f;
double decimal = f - integral;
int digits = 0;
while (decimal < 10) {
decimal *= 10;
digits++;
}
double ret = (int)decimal / Math.pow(10, digits);
ret += integral;
return Double.toString(ret);
}
public static void main(String args[]) {
final int TESTS = 1000000;
double[] floats = new double[TESTS];
Random random = new Random();
for (int i = 0; i < TESTS; ++i) {
int zeros = random.nextInt(6) + 3; // divide by 10^zeros
double digits = random.nextInt(100) + 100; // 3 last digits
floats[i] = digits / Math.pow(10,zeros) + random.nextInt(20) + 1;
}
long startTime = System.nanoTime();
for (int i = 0; i < TESTS; ++i)
truncateTo2NonZero(floats[i]);
long endTime = System.nanoTime();
long duration = endTime - startTime;
System.out.println(duration / 1000000); // in milliseconds

How to subscribe to multiple BluetoothLE Characteristics with Android | <p>I am developing an Android app which should subscribe to multiple BLE characteristics.</p>
<p>But whatever I do, I receive only the updated values from one characteristic.</p>
<p>Here is the code:</p>
<pre><code>BluetoothGattCharacteristic characteristicVel = gatt.getService(BleDefinedUUIDs.Service.KOMMMODUL_SERVICE).getCharacteristic(BleDefinedUUIDs.Characteristic.VELOCITY);
gatt.setCharacteristicNotification(characteristicVel, true);
BluetoothGattDescriptor descriptorVel = characteristicVel.getDescriptor(
BleDefinedUUIDs.Descriptor.CHAR_CLIENT_CONFIG);
descriptorVel.setValue(BleDefinedUUIDs.Descriptor.ENABLE_NOTIFICATION_VALUE);
gatt.writeDescriptor(descriptorVel);
BluetoothGattCharacteristic characteristicAcc = gatt.getService(BleDefinedUUIDs.Service.KOMMMODUL_SERVICE).getCharacteristic(BleDefinedUUIDs.Characteristic.ACCELERATION);
gatt.setCharacteristicNotification(characteristicAcc, true);
BluetoothGattDescriptor descriptorAcc = characteristicAcc.getDescriptor(
BleDefinedUUIDs.Descriptor.CHAR_CLIENT_CONFIG);
descriptorAcc.setValue(BleDefinedUUIDs.Descriptor.ENABLE_NOTIFICATION_VALUE);
gatt.writeDescriptor(descriptorAcc);
</code></pre>
<p>Whatever I do I get only the velocity data. If I change the order of the two blocks I get acceleration only but no more velocity data.</p>
<p>What have I to do in order to subscribe to many characteristics at once?</p>

React native background image warning: Invalid props.style key `resizeMode` supplied to `View` | <p>Gathering guidance from <a href="https://stackoverflow.com/questions/29322973/whats-the-best-way-to-add-a-full-screen-background-image-in-react-native">this post</a> about how to create a background image in RN I learned that I need to have an Image containing other elements:</p>
<pre><code> <Image style=... source=...>
<Text>Hello</Text>
</Image>
</code></pre>
<p>However, I think that when an Image has inner elements RN converts it to a view. I came to this conclusion because I am getting this warning:</p>
<p><a href="https://i.stack.imgur.com/0ji2g.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/0ji2g.png" alt="warning about view properties"></a></p>
<p>This is peculiar as the resizeMode was supplied to an Image and not to a View. The style of the containing image as described in the warning:</p>
<pre><code>{
width: null,
height: null,
overflow: "hidden",
flex: 1,
flexDirection: "column",
justifyContent: "space-between",
alignItems: "stretch",
resizeMode: "cover"
}
</code></pre>
<p>Should I ignore this warning or is there a proper way to create these kind of structures:</p>

Java Oracle connection - Connection has already been closed | <p>I simplify the code as below:</p>
<pre><code>Connection conn = dataSource.getConnection();
UserTransaction ut = util.getTransaction();
// ut.begin();
for (xxx) { // heavy for-loop, a lot of records
ut.begin();
PreparedStatement pstmt = conn.prepareStatement(sql); // very fast sql update
pstmt.executeUpdate();
pstmt.close();
ut.commit();
}
//ut.commit();
</code></pre>
<p>As the code above, the <code>for-loop</code> will be running very long, around 1-2 hour.</p>
<p>Last time, when I put the <code>begin</code> and <code>commit</code> outside of <code>for-loop</code>, I encounter an error in the end of loop:</p>
<pre><code>java.sql.SQLRecoverableException: IO Error: Connection timed out
at oracle.jdbc.driver.T4CPreparedStatement.executeForRows(T4CPreparedStatement.java:1065)
at oracle.jdbc.driver.OracleStatement.doExecuteWithTimeout(OracleStatement.java:1329)
</code></pre>
<p>Then I realize, system not able to commit because in this case, <code>UserTransaction</code> maybe already timeout. (error throw at the <code>ut.commit()</code>)</p>
<p>So I move the <code>begin</code> and <code>commit</code> into the <code>for-loop</code> to avoid the issue, but I got another error in somewhere around 1 hour and half:</p>
<pre><code>java.sql.SQLException: Connection has already been closed.
at weblogic.jdbc.wrapper.PoolConnection.checkConnection(PoolConnection.java:62)
at weblogic.jdbc.wrapper.Connection.preInvocationHandler(Connection.java:100)
at weblogic.jdbc.wrapper.Connection.prepareStatement(Connection.java:553)
</code></pre>
<p>My code is single threaded, so I am very sure, there is no other thread that close the <code>conn</code> connection. (this time the error throw at <code>conn.prepareStatement(sql)</code>)</p>
<p>And due to the <code>for-loop</code>, the connection is not idle, because it keep doing <code>update</code> and <code>commit</code>. How can a connection auto-closed (due to whatever reason? timeout?)?</p>
<p>So what happen to the connection? I searched but can't find any timeout settings like connection's pool borrow timeout or blah blah blah. </p>
<p>Anyone has idea?</p> | 2 |
setjmp/longjmp between threads to handle timeout | <p>I'm porting a software from an embedded computer to a Linux machine. (Ubuntu 14.04 or Raspbian (raspberry pi))</p>
<p>The original program was using setjmp/longjmp to handle timeout and CTRL+C event. It was running on a Microcontroller with a single main (one thread).</p>
<p>I'm trying to have a similar behaviour while using threads (pthreads).</p>
<p>The idea is that I want either a timeout or a CTRL+C to restart an infinite loop.</p>
<p>The original code was doing something like the code below. I don't mind to drop the setjmp/longjmp by something else. (ex: try/catch or signal or pthread_kill, conditional variable, etc..)</p>
<p>Any idea how to implement similar behavior with C/C++ ?</p>

#define TICK_PER_SEC (NS_PER_SEC/TICK_NS_TIME) // Number of tick per second (Ex:100)

How to compare files using Byte Array and Hash | <h2>Background</h2>

{
Thread.Sleep(500);

//Get byte sig of file and if seen before dont process
byte[] myFileData = File.ReadAllBytes(file);
byte[] myHash = MD5.Create().ComputeHash(myFileData);

Calculating Average from a list of students taken from a .txt file | <p>I have a separated .txt file in which there is a list of "students" with their own mark on the side that goes from 0 to 10, here is an example on how the .txt looks like:</p>
<blockquote>
<p>Mark 2<br>
Elen 3<br>
Luke 7<br>
Elen 9<br>
Jhon 5<br>
Mark 4<br>
Elen 10<br>
Luke 1<br>
Jhon 1<br>
Jhon 7<br>
Elen 5<br>
Mark 3<br>
Mark 7 </p>
</blockquote>
<p>What I want to do is calculating the Average of each student (expressed in <code>double</code>) so that the output would look like this:</p>
<pre><code>Mark: 4.0
Elen: 6.75
Luke: 4.0
Jhon: 4.33
</code></pre>
<p>Here is what I've come up with, for now I've only managed to use <code>Properties</code> to list the student names without repetition, but the number shown on the side of each one of them is obviously the last one the program finds.<br>
I've included it on a button actionlistener as I'm implementing a GUI, by pressing the button the output shown above is <code>append</code> in a <code>TextArea</code>: </p>
<pre><code> b1.addActionListener(new ActionListener() {

try {
File file = new File("RegistroVoti.txt");
FileInputStream fileInput = new FileInputStream(file);
Properties properties = new Properties();
properties.load(fileInput);
fileInput.close();
Enumeration enuKeys = properties.keys();
while (enuKeys.hasMoreElements()) {
String key = (String) enuKeys.nextElement();
String value = properties.getProperty(key);
l1.append(key + ": " + value + "\n");
}
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
});
</code></pre>
<p>I was thinking to use <code>Collectors</code> to calculate the average, but I actually don't know how to implement it...</p>
<p>Any help is appreciated!</p>
<p>Thanks in advance!</p> | 2 |
iOS Metal – reading old values while writing into texture | <p>I have a kernel function (compute shader) that reads nearby pixels of a pixel from a texture and based on the old nearby-pixel values updates the value of the current pixel (<em>it's not a simple convolution</em>).</p>
<p>I've tried creating a copy of the texture using <code>BlitCommandEncoder</code> and feeding the kernel function with 2 textures - one read-only and another write-only. Unfortunately, this approach is GPU-wise time consuming.</p>
<p>What is the most efficient (GPU- and memory-wise) way of reading old values from a texture while updating its content?</p> | 2 |
Late Static Binding and Instance Methods in TypeScript | <p>Am very curious how/why the following trickery is needed in TypeScript. Was playing around with basic <code>class</code> and <code>static</code> constructs, then inheritance, and finally referencing <code>static</code> properties from <code>instance</code> methods. I might not ever implement anything this way... but I did get quite confused <em>why</em> the following works:</p>
<pre><code>class Foo {
msg: string;
static name: string = 'Foo';
static sayHi(): string {
return `hello from ${this.name}`;
}
constructor() {
// this.msg = `I am ${Foo.name}`;
// 2x `I am Foo`
// this.msg = `I am ${this.name}`;
// error TS2339: Property 'name' does not exist on type 'Foo'.
// this.msg = `I am ${this.constructor.name}`;
// error TS2339: Property 'name' does not exist on type 'Function'.
const cls = <typeof Foo>this.constructor;
this.msg = `I am ${cls.name}`;
}
}
class Bar extends Foo {
static name: string = 'Bar';
}
console.log(Foo.sayHi()); // hello from Foo
console.log(Bar.sayHi()); // hello from Bar
console.log((new Foo()).msg); // I am Foo
console.log((new Bar()).msg); // I am Bar
</code></pre>
<p>(i'm on <code>tsc 1.8.10</code>, the <strong>UPDATE</strong> in <a href="https://stackoverflow.com/a/29244254/1345249">this answer</a> got it working)</p>
<p>If you jump to @basarat's response, WHY does the type assertion magically make everything work?</p>
<p>Compared to similar python:</p>
<pre><code>class Foo(object):
name = 'Foo'
@classmethod
def sayHi(cls):
return 'hello from {}'.format(cls.name)
def __init__(self):
self.msg = 'I am {}'.format(self.name);
class Bar(Foo):
name = 'Bar'
print(Foo.sayHi()) # hello from Foo
print(Bar.sayHi()) # hello from Bar
print(Foo().msg) # I am Foo
print(Bar().msg) # I am Bar

Change a Style based on Visual State | <p><em>"Blend makes it simple to setup Visual States based on say <code>minWindowWidth</code>. But it would be very nice to have state-based Styles defined for <code>TextBlock</code> elements, say with <code>tag="header"</code>, <code>tag="body"</code>, and have the Setter change the Style automatically."</em></p>
<p>Maybe I wasn't explicit enough in my initial question, let me rephrase this.</p>
<p>I am resizing my application window from say Landscape to Portrait. My VisualStateManager has setters which adjust the page properties based on the new minimum width.</p>
<p>I have multiple TextBlocks (header,body, etc) and other controls with .Text (ToggleSwitch), that I want to automatically adjust FontSize based on the new width.</p>
<p>Aside from manually setting every single control by name in all the states, is there a way to have the VisualStateManager do it automatically for each 'type' of Text(body/header/etc)? My work around at the moment is to DataBind a Style for every .Text control and have the ViewModel do all the scaling. That works, but this is really something Blend is made for, right? So I must be missing the obvious way everyone is using.</p>
<p>Thanks for all the good comments so far.</p>
<pre><code> <VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="VisualStateGroup">
<VisualState x:Name="PhonePortrait">
<VisualState.StateTriggers>
<AdaptiveTrigger MinWindowWidth="{StaticResource NarrowMinWidth}"/>
</VisualState.StateTriggers>
<VisualState.Setters>
<Setter Target="SwitchStackPanel.(StackPanel.Orientation)" Value="Vertical"/>
<!-- Setter to change all Body textblocks to FontSize=8-->
<!-- Setter to change all Header textblocks to FontSize=10-->
<!-- Setter to change all ToggleSwitch.Text to FontSize=8-->

Why does PhpStorm report an "Argument type does not match" error? | <p>I am working on a <strong>PHP 7</strong> project with <strong>PhpStorm 10.0.2</strong>.</p>
<p>Whenever I declare a PHPDoc <code>@param</code> for an function parameter that has type hinting for a scalar type (<code>string</code>, <code>int</code>, ...) I get this warning:</p>
<blockquote>
<p>Argument type does not match</p>
</blockquote>
<p>Here is some sample code that PhpStorm complains about:</p>
<pre><code>class HostConfig
{
/**
* @var string
*/
private $hostname;
/**
* @var string
*/
private $domainname;
/**
* Creates a new instance of hte HostConfig model.
*
* @param string $hostname A host name (e.g. "dev", "int", "feature-xy")
* @param string $domainname A domain name (e.g. "example.com")
*
* @throws \InvalidArgumentException If the given $hostname is empty
* @throws \InvalidArgumentException If the given $domainname is empty
*/
public function __construct(string $hostname, string $domainname)
{
if (strlen(trim($hostname)) === 0) {
throw new \InvalidArgumentException("The host name cannot be empty");
}
if (strlen(trim($domainname)) === 0) {
throw new \InvalidArgumentException("The domain name cannot be empty");
}
$this->hostname = $hostname;
$this->domainname = $domainname;
}
}
</code></pre>
<p>And a screenshot of PhpStorm displaying the questionable "Argument type does not match"-hint for in the PHPDoc for an constructor that has two strongly typed string parameters:</p>

Get all React components inside of a React element | <p>Here is my code so far:</p>
<pre><code>var allComponents = []
function getAllComponents (el) {
if (!el) return
if (!el.type) return
allComponents.push(el.type)
// Try to get all children components
React.Children.forEach(el.props.children, getAllComponents)
}
</code></pre>
<p>I am trying to find "every" component that has been created inside of a react element, however the above code will only get the direct <code>props.children</code>.</p>
<p>This means that given this example React element:</p>
<pre><code>function ComponentA (props) {
return (
<div>
<h1>Stuff</h1>
<ComponentB/>
<ComponentC/>
{props.children}
</div>
)
}
var el = (
<ComponentA>
<ComponentD/>
<ComponentE/>
</ComponentA>
)
getAllComponents(el) //-> [ComponentA, ComponentD, ComponentE]
</code></pre>
<p>The output will only have <code>ComponentA</code>, <code>ComponentD</code> and <code>ComponentE</code>, not <code>ComponentB</code> or <code>ComponentC</code> since they are not located in <code>props.children</code> but are instead a part of the component.</p>
<p>Is there any way to also get <code>ComponentB</code> and <code>ComponentC</code> programatically (without doing something like refs since i'd prefer not to litter refs everywhere)?</p> | 2 |
How can I develop on remote server with netbeans | <p>I am developing a java web application with netbeans. The application has to run on a "strong" server and cant run on my computer for testing.</p>
<p>Today I developed and loaded the *.war file with the Tomcat Web Application Manager. This takes a long long time - 10 minutes. I assume that the time is needed to load all files (also libs) to the server each time.</p>
<p>Is there a way to develop with netbeans remote on the server or upload only the edited files? </p>
<p>Thank you! </p> | 2 |
NavMeshAgent stuck (outside) the NavMesh | <p>For enemies, I set a random position on the nav mesh every x seconds, so that the enemies walk around randomly. Here my scripts:</p>
<p>Random point (from the unity docs)</p>
<pre><code>bool RandomPoint (Vector3 center, float range, out Vector3 result)
{
for (int i = 0; i < 30; i++) {
Vector3 randomPoint = center + Random.insideUnitSphere * range;
NavMeshHit hit;
if (NavMesh.SamplePosition (randomPoint, out hit, 1.0f, NavMesh.AllAreas)) {
result = hit.position;
return true;
}
}
result = Vector3.zero;
return false;
}
</code></pre>
<p>My random movement script:</p>
<pre><code>IEnumerator Walking ()
{
if (!isFollowingPlayer && isServer) {
Debug.LogError ("-- Start Walking --");
agent.speed = 2;
Vector3 randomDirection;
bool blocked = RandomPoint (agent.transform.position, walkRadius, out randomDirection);
NavMeshHit hit;
blocked = NavMesh.Raycast (enemy.transform.position, randomDirection, out hit, NavMesh.AllAreas);
if (!blocked) {
geileMethodeZumZeichnen (agent);
target = hit.position;
agent.SetDestination (hit.position);
geileMethodeZumZeichnen (agent);
Debug.LogWarning ("Go to " + hit.position);
}
if (blocked) {
Debug.LogWarning ("-- BLOCKED --");
yield return new WaitForEndOfFrame ();
} else {
Debug.LogWarning ("-- WAIT --");
yield return new WaitForSeconds (5f);
}
StartCoroutine ("Walking");
}
}
</code></pre>
<p>The random walking generally works. However when a nav mesh agent is close to the border of the nav mesh, it appears that he "breaks out" and is then stuck to his position. He only "jitters around" outside the nav mesh. (red lines on the image : path)</p>
<p><a href="https://i.stack.imgur.com/gJaUY.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/gJaUY.png" alt="NavMesh"></a></p>
<p>Looks like they try to reach their position but can not enter the nav mesh again. I don't want them to leave in first place :)</p> | 2 |

How to open a context menu with right click on a ListViewItem | <p>The title pretty much says it all. Can someone explain to me how can I open a context menu by selecting and then right clicking on a <code>ListViewItem</code> of a <code>ListView</code>?</p>

if (e.Button == MouseButtons.Right)
{
if (listView1.FocusedItem.Bounds.Contains(e.Location) == true)
{
contextMenuStrip1.Show(Cursor.Position);
}
}
}

<p>But I don't know how to register this event handler with the <code>ListView</code>. Every time I try I get the error that the delegates parameters are wrong because I use <code>MouseEventArgs</code> instead of <code>EventArgs</code>.</p>
<p>This is the wrong code I'm using to register the <code>EventHandler</code></p>

Correct procedure for restarting local MongoDB when Mongoose schema is changed | <p>Hi all I'm new to learning how to develop with Node.js using Mongoose and Express. I have been having some issues with Mongodb not correctly reflecting my schema changes.</p>
<p>For example, I have written a model that supposedly auto-increment <code>_id</code> by 1 starting from 0 when each new document is inserted. I'm testing a few ways to do this model and so I'm constantly inserting different data.</p>
<p>I drop the collection each time to try to reinsert the data. However, <code>_id</code> instead of starting at 0, it starts at the previous largest <code>_id</code>. </p>
<p>This is just one of the issues that I have encountered. Some other similar Schema changes that I did on the fly also were not reflected.</p>
<p>I tried the following:</p>
<ul>
<li>Ending npm/nodemon</li>
<li>Ctrl+C from <code>mongo</code></li>
<li>shutdownServer from <code>mongo</code></li>
</ul>
<p>Is there something else that I need to shut down completely then restart before mongoose reflects the newest form of the schema? Thanks!</p> | 2 |

Sails.js downloading file | <p>I'm beginner in <code>sails.js</code> and I need to add some logic to existing server.
I need to retrieve image from shared network, so I added <code>ImageController.js</code> and action in it:</p>
<pre><code>module.exports = {
download: function(req, res) {
var run = req.param('run');
var test = req.param('test');
var file = req.param('file');
var path = util.format('\\\\tch-smain\\Share\\AutoTest\\Screenshots\\%s\\%s\\%s.jpeg', run, test, file);
fileAdapter.read(path)
.on('error', function (err){
return res.serverError(err);
})
.pipe(res);
}
};
</code></pre>
<p>Then I registered route in <code>config\routes.js</code>:</p>
<pre><code>'/img': 'ImageController.download'
</code></pre>
<p>But when I trying to execute <code>GET /img?run=a&test=b&file=c</code> I get 500 error <strong>Internal Server Error. Something isn't right here</strong>.
But file on <code>\\tch-smain\Share\AutoTest\Screenshots\a\b\c.jpeg</code> exists</p> | 2 |
Returning a string or an Int depending on input | <p>How do I write a function that takes as input an <code>Int</code> and returns that <code>Int</code> if it is <code>> 0</code> or otherwise return a dash <code>"-"</code> if it is <code>< 0</code>. I understand that Haskell is strict with its types, but is there a way around this?</p> | 2 |
Is there a way to match Regex based on previous capture group, not captured previously? | <p>Okay, so the task is that there is a string that can either look like <code>post</code>, or <code>post put</code> or even <code>get put post</code>. All of these must be matched. Preferably deviances like <code>[space]post</code>, or <code>get[space]</code> should not be matched.</p>
<p>Currently I came up with this </p>
<pre><code>^(post|put|delete|get)(( )(post|put|delete|get))*$
</code></pre>
<p>However I'm not satisfied with it, because I had to specify <code>(post|put|delete|get)</code> twice. It also matches duplications like <code>post post</code>.</p>
<p>I'd like to somehow use a backreference(?) to the first group so that I don't have to specify the same condition twice. </p>
<p>However, backreference <code>\1</code> would help me <strong>only</strong> match <code>post post</code>, for example, and that's the opposite of what I want. I'd like to match a word in the first capture group that was <strong>NOT</strong> previously found in the string.</p>
<p>Is this even possible? I've been looking through SO questions, but my Google-fu is eluding me.</p> | 2 |
Xcode 8 sets frame size differently. How do I find more details? | <p>In several places in my application I get zero frame sizes where I used to get a frame. This impacted me especially when creating round objects by doing a cornerRadius of <code>size/2</code>.</p>
<p>For example, in Xcode 7 this worked fine:</p>
<pre><code>class AvatarUIButton: UIButton {
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
layer.masksToBounds = true
layer.cornerRadius = bounds.size.width / 2
}
}
</code></pre>
<p>But now in Xcode 8 I have to do this:</p>
<pre><code>class AvatarUIButton: UIButton {
override var bounds: CGRect { didSet {
layer.cornerRadius = bounds.size.width / 2
}}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
self.layer.masksToBounds = true
}
}
</code></pre>
<p>In this example, the change is arguably better/more obvious. I have another situation that is much less isolated involving a 0 frame on TableHeaderView that is only for xcode 8.</p>
<p>I'm looking for release notes, mailing list discussion, or similar that discusses a change in ordering of frame size determination so I can figure out what changed and how I can fix it.</p> | 2 |
Hide a view when textView is too long | <p>I'm looking to hide a view if my textview is too long and it starts to touch it, how would I go about doing this? So for example like this is okay:</p>
<p><a href="https://i.stack.imgur.com/ooEqe.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ooEqe.png" alt="Normal Username length"></a></p>
<p>But when it's a long username and the length is nearer the time stamp I want to hide the timestamp, how would I go about doing this? Cannot think of it for the life of me! </p>

Android - Record Video and Set Video Size (Dimensions) | <p>I'm in the process of refactoring a piece of code that records videos (from the camera) ranging usually between 3 and 30 seconds in order to decrease the overall size (in bytes) of the video.</p>
<p>We were previously using <code>CamcorderProfile</code>, but it does not provide enough granularity for our application so I have now transitioned to manually adjusting all of the settings (audio source, video source, video frame rate, audio encoder, etc).</p>
<p>The issue is I cannot find a reliable method for selecting the optimal video size since there does not (to my knowledge) exist a universal list of sizes that all Android devices support. I would like the video to be as close to 480x360px as possible since we push our video to Amazon Elastic Transcoder, which makes the videos 480x360px in a variety of formats (mp4, webm, etc).</p>
<p>Below is a snippet of code of my general idea:</p>
<pre><code>List<Camera.Size> sizes = camera.getParameters().getSupportedVideoSizes();
Camera.Size s;
//
// select size from sizes???
//
recorder = new MediaRecorder();
camera.stopPreview();
camera.unlock();
recorder.setCamera(camera);
// configure recorder
recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
recorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);
recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
// WHAT IS THE SIZE??
recorder.setVideoSize(s.width, s.height);
recorder.setVideoFrameRate(15);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setVideoEncoder(MediaRecorder.VideoEncoder.H264);

<p>I have looked at a variety of posts on here as well as the Android Compatibility Definition Documents for 4.4 - 6.0.</p>

Drawing a FacetGrid of QQ-plots with seaborn | <p>I am unable to draw a <a href="https://stanford.edu/~mwaskom/software/seaborn/generated/seaborn.FacetGrid.html#seaborn.FacetGrid" rel="nofollow">FacetGrid</a> of <a href="https://en.wikipedia.org/wiki/Q%E2%80%93Q_plot" rel="nofollow">QQ-plots</a> with <a href="https://stanford.edu/~mwaskom/software/seaborn/index.html" rel="nofollow">seaborn</a>.</p>

Monitoring uwsgi with zabbix | <p>I would like to monitor uwsgi using zabbix. I found that there is some plugin for that:</p>
<pre><code>uwsgi --stats-push zabbix:127.0.0.1:10051,myinstance ...
</code></pre>
<p>but I'm not sure how it is supposed to work. It seems that uwsgi pushes all the stats to the target zabbix but I can't find a description of this stats, hence I don't know how to set item(s) on zabbix.</p>
<p>For the moment I don't see anything coming to my zabbix instance.</p> | 2 |
How to find the position of a word in a string / list? | <p>I'm writing a function where the user inputs a word, then inputs a string, and the function identifies all occurrences and the position of that word in a string (although it's actually converted to a list halfway through). </p>
<p>The code I have currently is only identifying the first occurrence of the word, and none further. It also doesn't identify the word if the word is the first word in the string, returning an empty list. It will also say the word's actual position - 1, as the first word is counted as zero. </p>
<p>I have attempted to curb this problem in two ways, the first of which doing a <code>aString.insert(0, ' ')</code>, the second of which doing <code>for i in __: if i == int: i += 1</code>. Neither of these work. </p>
<p>Also, when doing the <code>.insert</code>, I tried putting a character in the space instead of, well, a space (as this part doesn't get printed anyway), but that didn't work.</p>
<p>Here is the code:</p>
<pre><code>def wordlocator(word):
yourWord = word
print("You have chosen the following word: " +yourWord)
aString = input("What string would you like to search for the given word?")
aString = aString.lower()
aString = aString.split()
b = [(i, j) for i, j in enumerate(aString)]
c = [(i, x) for i, x in b if x == yourWord]
return c
</code></pre>
<p>The output I'm looking for is that if someone did...</p>
<pre><code>wordlocator("word")
"please input a string generic message" "that is a word"
"4, word"
</code></pre>
<p>Currently that would work, but it'd print <code>"3, word"</code>. If the string was <code>"that is a word and this is also a word"</code> then it'd ignore the further occurrence of <code>"word"</code>.
edit: Got it working now, used a simpler piece of code. Thanks for your help all!</p> | 2 |
Activator.CreateInstance with an Interface parameter | <p>I have a Reflection method, which I load an Instance of an class with a specific name. I have an abstract class which define my classes. Now I also have an interface in the constructor of this abstract class. It's a bit hard to explain and I'm not sure if it's a correct way to implement my problem. But here is my source code, which should explain the most:</p>
<p>Program:</p>
<pre><code> private static void Main(string[] args)
{
int result;
if (args.Length > 0)
{
string jobName = args[0];
Type[] types = Assembly.GetAssembly(typeof(Task)).GetTypes();
foreach (Type type in types)
{
if (type.Name == jobName)
{
//Here is my problem. I need my Interface instead of null
_job = (Task)Activator.CreateInstance(type, null);
}
}
if (_job != null)
{
result = _job.Run(args);
}
}
//Dispose the Job
_job = null;
}
</code></pre>
<p>Task:</p>
<pre><code>public abstract class Task
{
public IArgument Argument;
protected Task(IArgument argument)
{
Argument = argument;
}
public int Run(string[] args)
{
int result;
if (SetArguments(args))
{
result = Work();
}
return result;
}
protected abstract int Work();
</code></pre>
<p>Interface:</p>
<pre><code>public interface IArgument
{
bool SetArguments(string[] args);
}
</code></pre>
<p>Now I can create an "Task" class and an "Argument" class:</p>
<pre><code>public class ImportArgument : IArgument
{
public bool SetArguments(string[] args)
{
return true;
}
}
public class ImportTask : Task
{
protected override int Work()
{
return 1;
}
public ImportTask(IArgument argument) : base(argument)
{
Argument = new ArticleImportArgument();
}
}
</code></pre>
<p>What do you guys think. Is there a way where I can create an Instance of the task class with an Interface in the constructor? Is there another way to solve this problem? I could also create an abstract method in my Task class where I have to implement my Interface, but I think the constructor would be a better way.</p> | 2 |
Using EasyPHP Webserver | <p>I'm not sure how one goes about using EasyPHP Webserver. Looking around the internet there doesn't seem to be a lot of materials on the matter. Whenever I try to run a php file from the www folder, a new blank tab appears without output from script code (Simple hello world echo). I'm not sure what the problem could be. My Http server and db server is running.</p>
<p>I'm also not sure if EasyPHP devserver is capable of going online. I'm currently in the middle of building an application that requires information to be sent to the server. My android application has been having trouble connecting to the EasyPHP devserver. Will I have more success with EasyPHP Webserver than I will with Devserver?</p> | 2 |

Python filter doesn't work as expected | <p>I have the following Python code:</p>
<pre><code>a = [1,2,3,'4','55',6]
filter(int,a)
</code></pre>
<p>The output is:</p>
<pre><code>[1, 2, 3, '4', '55', 6]
</code></pre>
<p><code>filter()</code> is supposed to remove the elements from the provided sequence which translate into false, and return only those elements which translate into true. </p>
<p>I expected the output to be:</p>
<pre><code>[1,2,3,6]
</code></pre>
<p>since these are the only integers in my list.

How to create help buttons in Android? | <p>I currently have a homescreen with three buttons. I would like to add a small button on the side of each button that when clicked would pop up a some sort of pop-up, that would explain the functionality of each button. Is there a built-in function for this? Or is this more like a tool-tip?
Thank you</p> | 2 |
How to set Primary Key and Foreign key in Redis | <p>I have created two hash key value pair in <strong>Redis</strong> named <code>Person</code> and <code>Account</code>. The <code>Person</code> key has the first name and last name of the person and the <code>Account</code> Key contains account type and savings. Now I want to do a join similar to SQL joins(<code>inner join</code>) to retrieve the account type and savings of each person from both the hash values.</p>
<p>Kindly help me out to find a solution to this problem and could anyone please help me in setting a primary key and foreign key in Redis hash key value pairs.</p> | 2 |
How to find when a matrix converges with a loop | <p>I've been given a matrix:</p>
<pre><code>P <- matrix(c(0, 0, 0, 0.5, 0, 0.5, 0.1, 0.1, 0, 0.4, 0, 0.4, 0, 0.2, 0.2, 0.3, 0, 0.3, 0, 0, 0.3, 0.5, 0, 0.2, 0, 0, 0, 0.4, 0.6, 0, 0, 0, 0, 0, 0.4, 0.6), nrow = 6, ncol = 6, byrow = TRUE)
</code></pre>
<p>Using the functions, <code>mpow</code>, <code>rows_equal</code>, <code>matrices_equal</code>. I want to find when <code>P^n</code> converges, in other words what n is, when all the rows are equal in the matrix and when <code>P^n = P^(n+1)</code>.</p>
<p>By just looking at the functions <code>i</code> have managed to deduce that around <code>n=19-21</code> the matrix will converge. </p>
<p>Although, I want to find the right n using a loop. Here under are the functions <code>mpow</code>, <code>rows_equal</code> and <code>matrices_equal</code>. I know they can be written differently but please keep them as they are. </p>
<pre><code>mpow <- function(P, n, d=4) {
if (n == 0) diag(nrow(P)))
else if (n== 1) P
else P %*% mpow(P, n - 1))
}
rows_equal <- function(P, d = 4) {
P_new <- trunc(P * 10^d)
for (k in 2:nrow(P_new)) {
if (!all(P_new[1, ] == P_new[k, ])) {
return(FALSE)}
}
return(TRUE)
}
matrices_equal <- function(A, B, d = 4) {
A_new <- trunc(A * 10^d)
B_new <-trunc(B * 10^d)
if (all(A_new == B_new)) TRUE else FALSE
}
</code></pre>
<p>Now, to write the loop, we should do it something along the lines of:</p>
<p>First creating a function like so:</p>
<pre><code>when_converged <- function(P) {...}
</code></pre>
<p>and </p>
<pre><code>for (n in 1:50)
</code></pre>
<p>To try for when t.ex n = 50. </p>
<p>Although i don't know how to write the code correctly to do so, can anyone help me with that? </p>
<p>Thank you for reading my question.</p> | 2 |
xdata and ydata must be the same length | <p>I am trying to get my plot of temperature data to update by replacing the past 10 iterations with the next 10 as seen in the code before but I keep getting a "xdata and ydata must be the same length" error. Along with fixing the error, is this the best way to do such a task of replacing a certain amount of old data with new data on a real time plot? Note: there is a little more code in the file but it is just for opening and reading the labjack equipment</p>
<pre><code>temperature = []
x = list()

temperature.append(tempC)
dT = temperature[i]-temperature[i-1]

else:

Safari(iOS): Embed YouTube Video Always Plays In Low Quality | <p>I need to play YouTube Videos with at least 720p resolution on my mobile tv web app, but safari plays them always with the lowest quality, that sucks. </p>
<p>I tried a lot of solutions that have been already posted, but they seem to be outdated. e.g. <code>&vq=hd720</code>, <code>&hd=1</code>, <code>&vq=hd1080</code> appending to the embed iframe, unfortunately it's not working.</p>
<p>I also tried to do it with the youtube javascript api, what a surprise, no luck either. </p>
<p>Any other solutions I could try? The Videos are uploaded in portrait format 720x1280.</p> | 2 |

Gulp and absolute path | <p>I am new in Gulp.
I was wondering if I could have an absolute path for source like the code below:</p>
<pre><code>var gulp = require('gulp');
var concat = require('gulp-concat');
var minify = require('gulp-minify-css');
gulp.task('hello', function() {
return gulp.src(['C:\a\b\c\css\fonts.css',
'C:\a\b\c\css\common.css',
'C:\a\b\c\css\generic.css'])
.pipe(concat('stylestest.css'))
.pipe(minify())
.pipe(gulp.dest('web'));
});
</code></pre>
<p>If not, is it possible to put gulp project and web application next to each other, instead of putting web application inside the gulp project directory.
Actually, I don't want to change current structure of my project but I see people copy app inside gulp project folder.</p> | 2 |
Python udp performance | <p>I am setting up a pretty simple message server using TCP and UDP on different ports on a Raspberry PI 2 with wifi. I am using UDP for multi-cast. The server works fine. The problem is that the processor jumps to about 30% processor usage when I run the server (TCP and UDP listeners). This isn't processing anything, just listening. When I shut down the UDP it goes to about 3-5%. Is this normal (it is a RPi), or am I doing something wrong? Here is the code for initializing the UDP listener:</p>
<pre><code>class UDPServer(asyncore.dispatcher):
def __init__(self):
asyncore.dispatcher.__init__(self)
multicast_group = '224.3.29.71'
server_address = ('', 8081)
# Create the socket
self.create_socket(socket.AF_INET, socket.SOCK_DGRAM)
# Bind to the server address
self.bind(server_address)
group = socket.inet_aton(multicast_group)
mreq = struct.pack('4sL', group, socket.INADDR_ANY)
self.setsockopt(socket.IPPROTO_IP, socket.IP_ADD_MEMBERSHIP, mreq)
print("UDP listening on {}:{}".format(multicast_group,8081))

how Do I structure/compile my ruby project | <p>im brand new to Ruby and I just finished coding a program.</p>
<p>the program has about 350 lines of code, 6 methods but no classes. it uses constants and global variables.</p>
<p>Is it convention to, for example, have the global variables/constants in a seperate file? should I split all the methods into different files?</p>
<p>What should the folders be like where I have all the files?</p>
<p>and Lastly, how do i create a makefile (or rakefile whatever it's called. i have the rake rubygem)</p>

"Changes are not allowed while code is running" | <p>I am constantly going back and forth between my code in Visual Studio 2015 and my browser. When I forget to turn off the debugger before trying to make edits I get this error:</p>
<blockquote>
<p>Changes are not allowed while code is running.</p>
</blockquote>
<p>It comes with an annoying bleep sound and a popup. Is there a way to make that go away and have Visual Studio simply stop my code automatically when it clearly sees I am trying to make edits?</p>
<p>It's normally fine, I simply click ok, manually stop my code and then try the edits again. The problem is when I am on a stubborn piece of code that doesn't want to work and I am going back and forth I sometimes forget to stop the code. At that point I am frustrated already because of the code and then to get this stupid popup with a bleep sound is enough to send me into a rage of cursing.</p> | 2 |
What is safe method to perform `Object.assign` when using AngularJS? | <p>Basically I would like to perform <code>Object.assign</code> to get copy of my data, without anything that AngularJS attached in the past, it attaches now, or may attach in future versions.</p>
<p>Sure I can delete such property as <code>$$hashKey</code> after assignment but this approach is totally fragile, on the other hand I could manually construct the object with fields I want but this on the other hand is tiresome (and also fragile if I change definition of my source object).</p>
<p>Is there something solid in between?</p> | 2 |

To complicate matters, the Active Directory doesn't have groups set up as group elements - all users in the AD are objectClass=User and objectCategory=Person.</p>
<p>My question is: how can I write a query that will match a user to all their "memberOf" elements without knowing necessarily what the group names are (since they might change, etc.)? From there, I think I can piece together how to match each element to the reports.</p>
<p>EDIT: Here's what I have written so far. It's not creating the procedure because of a syntax error, but I can't spot the error.</p>
<pre><code>USE [ReportServer]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE PROCEDURE [dbo].[ActiveDirectoryPermissions]
AS
BEGIN
SET NOCOUNT ON;
DECLARE @Table1 TABLE
(
[GroupName] nvarchar(MAX),
[GroupPath] nvarchar(MAX)
)
INSERT INTO @Table1 ( [GroupName], [GroupPath] )
SELECT sAMAccountName as [GroupName], replace(ADsPath,'LDAP://','') as [GroupPath]
FROM OPENQUERY( ADSI,
'SELECT sAMAccountname, ADsPath
FROM ''LDAP://DC=[REDACTED],DC=COM''
WHERE objectCategory=''group'' AND CN=''*''
ORDER BY CN')
DECLARE @Table2 TABLE
(
[GroupPath] nvarchar(MAX),
[MemberName] nvarchar(MAX)
)
DECLARE table_1_cursor CURSOR FOR
SELECT GroupPath
FROM @Table1 t1
DECLARE @SQL nvarchar(MAX)
DECLARE @temp nvarchar(MAX)
OPEN table_1_cursor
FETCH NEXT FROM table_1_cursor INTO @temp
WHILE @@FETCH_STATUS = 0
BEGIN
SET @SQL = 'SELECT '''+@temp+''' AS GroupPath, cn
FROM OPENQUERY(ADSI,
''SELECT cn
FROM ''''LDAP://DC=[REDACTED],DC=com''''
WHERE
memberOf='''''+@temp+'''''
'')'
INSERT INTO @Table2 ( [GroupPath], [MemberName] )
EXEC sp_executesql @SQL;
FETCH NEXT FROM table_1_cursor INTO @temp
END
CLOSE table_1_cursor
DEALLOCATE table_1_cursor
SELECT *
FROM @Table2 t2
INNER JOIN @Table1 t1 ON (t2.GroupPath=t1.GroupPath)

UTF to ASCII Conversion | <p>I am using Java web service to call an oracle procedure to read some records. The executing of this Java web service is automated with the help of Shell Script.
So the flow is like:</p>
<p>Shell scripts calls the Java Web service, further Java web service calls the Oracle stored procedure to read some records.</p>
<p>As an end product a feed file is generated which is in UTF-8 format and we need our file to be created in ASCII. So could any one help me with some Linux or Java code which I could add to my shell script or Java code to convert the file to ASCII.</p>
<p>P.S. I am aware about converting the file from UTF to ASCII with help of NOTEPAD++, but i need this process to be automated. Any help would be highly appreciated. </p> | 2 |
Add object using ng-model | <p>I have a form which updates values on submit like this</p>

Get the most recent file | <p>Using</p>
<pre><code>DirectoryStream<Path> stream = Files.newDirectoryStream(dir,pattern);
</code></pre>
<p>I get a <code>DirectoryStream</code> of files in my <code>dir</code> which match <code>pattern</code>. But I'm not interested in all those files. I only want to get the most recent one and I know that the filename of the most recent one is the largest filename in terms of lexicographical order (because the timestamp is included). What is the easiest way to get this file? Is it always the one which comes last in my stream? What would you do?</p> | 2 |

Downloading and Installing IPA from server if user clicks on button on Iphone | <p>I am working on an app where I deploy the .ipa file and manifest.plist on my server and from there I try to install the app to my iphone. </p>
<p>The app is initially installed but I need to check if a latest version is available on the server. I have done this part and now wish to install the latest .ipa from the server directly to my phone without redirecting user to the html page of the server</p>
<p>Found some links on stack overflow, especially this:
<a href="https://stackoverflow.com/questions/23561370/download-and-install-an-ipa-from-url-on-ios">Download and install an ipa from url on iOS</a>

</code></pre>
<p>I get unsupported URL exception. Can anyone tell me how I can achieve this? Is there any other way to directly start installing the upgrade without navigating to the actual html page?</p> | 2 |

[Laravel 5.1]Custom routes display a white (blank) page | <p>Im currently using XAMPP (PHP 5.6.21) on a Win 10 machine.</p>
<p>Im doing a migration from a site in .net to laravel. Until now i almost had no problem, most of the previous problems came from inexperience. But i can't find solutions for this error.</p>
<p><strong><em>routes.php</em></strong></p>
<pre><code>//Operaciones
Route::resource('operaciones', 'OperacionesController');
//Ruta al cierre de Operaciones
Route::any('operaciones/cerrar', ['as' => 'operaciones/cerrar', function(){
dd('asdasd');
}]);
</code></pre>
<p>The resource route works fine, but the 2nd route brings me a white (blank) page</p>
<p>And does not matter if i put anything in the web browser</p>
<p>if i put</p>
<pre><code>http://localhost:8080/mutualv0/public/operaciones/asdasdasd
</code></pre>
<p>white page, if i put</p>
<pre><code>http://localhost:8080/mutualv0/public/operaciones/cerrar

<p>withe again...</p>
<p>But, if y try this</p>
