Simple Xml - Element Declared Twice Error

<p>I have been trying to wrap a set of classes based on Simple XML (Java Serializer) around a RSS Feed. The sample feed is </p>

</code></pre>
<p>The error that I am getting while running the code is </p>
<pre><code>org.simpleframework.xml.core.PersistenceException: Element 'link' declared twice at line 24
</code></pre>
<p>And the error is fair enough because the particular element name occurs twice in the xml but in different ways.</p>
<p>The first link element is here</p>
<pre><code><link>http://www.codinghorror.com/blog/</link>
</code></pre>
<p>Its directly under the Channel tag. And then the next link tag is again under Channel in the following format</p>
<p><code><atom10:link xmlns:atom10="http://www.w3.org/2005/Atom" rel="self" type="application/rss+xml" href="http://feeds.feedburner.com/codinghorror" /></code></p>
<p>In Channel.java class I cannot have two variables with the same name link. I tried changing a variable name to blogLink and tried giving name in the Element annotation and Eclipse gave me this error</p>
<pre><code> Change was
@Element("name=link")
Result is
The attribute value is undefined for the annotation Element
</code></pre>
<p>I know I am missing something here but I am not able to put my finger on it. I would appreciate any help on this.</p>
<p>UPDATE</p>
<p>Channel Class</p>
<pre><code>@Element(name="link")
@Namespace(reference="http://www.w3.org/2005/Atom",prefix="atom")
private atomlink atomlink;
public atomlink getAtomLink() {
return atomlink;
}
</code></pre>
<p>Link Class</p>
<pre><code> import org.simpleframework.xml.Attribute;
import org.simpleframework.xml.Namespace;
import org.simpleframework.xml.Root;
@Root(name="link")
@Namespace(reference="http://www.w3.org/2005/Atom",prefix="atom10")
public class atomlink {
@Attribute
private String rel;
public String getRel() {
return rel;
}
</code></pre>
<p>}</p>
<p>I have changed the class names and yet it still points to the same error.</p>

XML schema to java classes using XJC

<p>I am using an oficial XSD schema downloaded from here:</p>

<p>What I tried was to not use the oficial XSD and generate my own using trang.jar. The result was good, I got my generated java classes but when I create a XML document with JAXB (using those classes) the namespaces are not ok.</p>
<p>So, what I want is to use the oficial XSD but modified (maybe) to make it work.</p>
<p><strong>How can I solve this to get my generated classes?</strong> </p>
<p>Thanks in advance.</p>

Databinding the color of a RadialGradient brush in silverlight 3
|
<p>I am trying to databind the color of a RadialGradientBrush in silverlight 3 to a property, but just can't seem to get it to work.</p>
<p>For example, in a sample test app all I have is </p>
<pre><code><navigation:Page x:Class="SilverlightNavigator.HomePage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
x:Name="HomePageUC"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:navigation="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Navigation"
Title="HomePage Page">
<Grid x:Name="LayoutRoot" Background="White">
<StackPanel>
<TextBlock
DataContext="{Binding ElementName=HomePageUC}"
Text="{Binding TestColorOne}" />
<Rectangle x:Name="testRectangle" Height="100" Width="100"
DataContext="{Binding ElementName=HomePageUC}" >
<Rectangle.Fill>
<RadialGradientBrush>
<GradientStop Color="{Binding TestColorOne}" Offset="0" />
<GradientStop Color="{Binding TestColorTwo}" Offset="1"/>
<!--
<GradientStop Color="#FFFF0000" />
<GradientStop Color="#FF00FF00" Offset="1"/>
-->
</RadialGradientBrush>
</Rectangle.Fill>
</Rectangle>
</StackPanel>
</code></pre>
<p>In the code behind, I have even made them dependency properties like this ..</p>
<pre><code> public static readonly DependencyProperty TestColorOneProperty =
DependencyProperty.RegisterAttached("TestColorOne", typeof(Color), typeof(HomePage), null);
public static readonly DependencyProperty TestColorTwoProperty =
DependencyProperty.RegisterAttached("TestColorTwo", typeof(Color), typeof(HomePage), null);
public Color TestColorOne
{
get { return (Color)GetValue(TestColorOneProperty); }
set { SetValue(TestColorOneProperty, value); }
}
public Color TestColorTwo
{
get { return (Color)GetValue(TestColorTwoProperty); }
set { SetValue(TestColorTwoProperty, value); }
}
</code></pre>
<p>But this still gives me the very unhelpful AG_E_PARSER_BAD_PROPERTY_VALUE exception. If I uncomment the two Xaml lines where the colors are hard coded, it works fine. I know the properties are fine because if I hard code the colors or comment out the rectangle, it displays the text fine. (Via the binding to the TextBlock) </p>
<p>I have also tried passing in the string "Red", "Blue" etc. instead of the color object. But the binding just doesn't seem to work.</p>
<p>Any advice?</p>

RecyclerView notifyItemInserted duplicates previous entry's data
|
<p>So for some reason whenever I add a new item to my ArrayList and notify the recyclerview that it's been added, it duplicates the previous entry's data. So the view gets created but with data from the last entry not the current data.</p>
<p>What's strange is that I save the items using ORM Sugar, and so when I retrieve them the correct data is displayed. Which shows that the data is getting added but the view is not showing it correctly.</p>
<p>I can only assume recyclerview is not calling the onBindViewHolder whenever I use the method notifyItemInserted, <strong>because the correct data is shown when I use notifyDataSetChange()</strong></p>
<p>Here's my method to add the new item</p>
<pre><code>@Override
public void AddCalorieToHistoryList(int calorieAmount, int currentCalorieAmount) {
// Get the date and the calorie amount from what the user entered.
Date date = new Date();
// Create the calorie history item and then save it (via ORM Sugar Library)
CalorieHistory calorieHistory = new CalorieHistory(date.toString(), calorieAmount);
calorieHistory.save();
// Notify the view of the new item that should be inserted.
historyView.InsertNewListItem(calorieHistory);
SubtractFromCurrentCalorieAmount(calorieAmount, currentCalorieAmount);
}
</code></pre>
<p>historyView's method</p>
<pre><code>@Override
public void InsertNewListItem(CalorieHistory calorieHistoryItem) {
// Add the new item
calorieHistories.add(calorieHistoryItem);
// Notify the insert so we get the animation from the default animator
historyListAdapter.notifyItemInserted(0);
}
</code></pre>
<p>Here's the recyclerview adapter</p>
<pre><code>public class HistoryListAdapter extends RecyclerView.Adapter<HistoryListAdapter.HistoryListViewHolder> {
List<CalorieHistory> calorieHistoryList;
public HistoryListAdapter(List<CalorieHistory> historyList) {
this.calorieHistoryList = historyList;
}
// I think this is run once, it generates the view holder from the layout that we are using for each list item.
// This way it won't have to grab it each time we make a new list item. It's all stored on our view holder.
@Override
public HistoryListViewHolder onCreateViewHolder(ViewGroup parent, int i) {
View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.calorie_history_item, parent, false);
return new HistoryListViewHolder(itemView);
}
// This executes everytime we make a new list item, it binds the data to the view.
@Override
public void onBindViewHolder(HistoryListViewHolder holder, int position) {
// Get the current calorHistory object and set it's data to the views.

Objective C Dynamic NSDictionary for UI Table View divided by Section Headers
|
<p>So this is based off of my question here</p>
<p><a href="https://stackoverflow.com/questions/14493725/objective-c-when-to-use-nsdictionary-instead-of-nsarray#comment20201177_14493725">objective c when to use NSDictionary instead of NSArray</a></p>
<p>Apologies for the noob questions. I just started learning objective c and I'm really confused. </p>
<pre><code>- (void)viewDidLoad
{
[super viewDidLoad];
headers = [NSArray arrayWithObjects:@"Header Section 1 (H1)", @"Header Section 2 (H2)", nil];
events = [NSArray arrayWithObjects:@"H1 Content 1", @"H1 Content 2", nil];
myInfo = [NSArray arrayWithObjects:@"H2 Content 1", @"H2 Content 2", @"H2 Content 3", nil];
menuDetails = [[NSMutableDictionary alloc] init];
for(NSString *event in events){
[menuDetails setValue:event forKey:@"Header Section 1 (H1)"];
}
for(NSString *info in myInfo){
[menuDetails setValue:info forKey:@"Header Section 1 (H2)"];
}
}
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{
return [[menuDetails allKeys] count];
}
-(NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section{
return [[[menuDetails allKeys] sortedArrayUsingSelector:@selector(localizedCaseInsensitiveCompare:)]objectAtIndex:section];
}
</code></pre>
<ol>
<li><p>Wanted to limit this for the First Section but not on the 2nd section</p>
<pre><code>-(NSInteger)tableView:(UITableView *)tableview numberOfRowsInSection:(NSInteger)section {
return 5;
}
</code></pre></li>
<li><p>So I'm not really sure how to make this dynamic when I try to fill up the cells with this method. I'm not really sure how to make sure it selects the "Key" of the section the specific cell is at (blocked line) :</p></li>
</ol>
<hr>
<pre><code>-(UITableViewCell *)tableView:(UITableView *) tableView cellForRowAtIndexPath:(NSIndexPath *) indexPath {
static NSString *CellIdentifier = @"OptionCellIdentifier";
MenuOptionTableCell *cell = (MenuOptionTableCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(cell == nil){
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"OptionCellIdentifier" owner:self options:nil];
cell = [nib objectAtIndex:0];
}
NSDictionary *menuItem = [[menuDetails valueForKey:[[[menuDetails allKeys] sortedArrayUsingSelector:@selector(localizedCaseInsensitiveCompare:)] objectAtIndex:indexPath.section]] objectAtIndex:indexPath.row];
cell.optionName.text = [menuItem objectForKey:@"Events"];
return cell;
}
</code></pre>
<p>EDIT: GAAAHHH, the formatting is killing me. It won't get inside the code markup</p>
<p>This is where Idk what to do:</p>
<blockquote>
<p>cell.optionName.text = [menuItem objectForKey:@"Events"];</p>
</blockquote>
<p>So what I wanted to happen is:</p>
<ul>
<li>Section Header 1
<ol>
<li>H1 Content 1</li>
<li>H1 Content 2</li>
</ol></li>
<li>Section Header 1
<ol>
<li>H2 Content 1</li>
<li>H2 Content 2</li>
<li>H1 Content 3</li>
</ol></li>
</ul>

how to use multithreading with pika and rabbitmq to perform Requests and Responses RPC Messages
|
<p>I'm working on a Project with Rabbitmq, I'm using the RPC Pattern, basically I'm receiving or consuming Messages from a Queue, make some Processing and then send a Response back. Im using Pika, my goal is to use a Thread per Task so for every Task i ll make a Thread perticularly for that Task. I also read that the best Practice is to make only one Connection and under it many channels as i want to, but i get always this Error :<br />
'start_consuming may not be called from the scope of '
pika.exceptions.RecursionError: start_consuming may not be called from the scope of another BlockingConnection or BlockingChannel callback.</p>
<p>I made some Research and found out that Pika is not thread safe and we should use for every Thread an Independant Connection and a channel. but i dont want to do that since it is considered bad Practice. So I wanted to ask here if someone already achieved to make this work. I read also that it is Possible if i didn't use BlockingConnection to instantiate my Connection and also that there is a Function called add_callback_threadsafe which can make this Possible. but there is unfortunally no Examples for that and I read the Documentation but it's complex and without Examples it was hard for me to grasp what they want to describe.</p>
<p>my Try was to declare two Classes. Each class will represent a Task Executer which receive or consume a message from a queue and based on that made some Processing and deliver a Response back. my idea was to share a rabbitmq Connection between the two Tasks but every Task will get an independant Channel. in the Code above the rabbit Parameter passed to the function is a Class that holds some Variables like Connection and other Functions like EventSubscriber which when called it will assign a new Channel and start consuming messages from that Particular Exchanges and routingKey. Next i declare a Thread and give the subscribe or Consume function as a Target to that Thread. the other Task Class look also the same as this Class that's why i ll only upload this Code. in the main Class i make a Connection to rabbitmq and pass it as Parameter to the constructor of the Two Task Classes.</p>
<p>class On_Deregistration:</p>
<pre><code>def __init__(self, rabbit):
self.event(rabbit) # this will call event function and pass the connection shared between all Tasks. rabbit parameter hold a connection to rabbitmq
def event(self, rabbit):
self.Subscriber = rabbit.EventSubscriber(rabbit, 'testing.test', 'test', False, onDeregistrationFromHRS # this func is task listener)
def subscribeAsync(self):
self.Subscriber.subscribe() # here i call start_consuming
def start(self):
"""start Subscribtion in an Independant Thread """
thread = threading.Thread(target = self.subscribeAsync )
thread.start()
if thread.isAlive():
print("asynchronous subscription started")
</code></pre>
<hr />
<h1>MAin Class:</h1>
<p>class App:</p>
<pre><code>def __init__(self):
self.rabbitMq = RabbitMqCommunicationInterface(host='localhost', port=5672)
firstTask = On_Deregistration(self.rabbitMq)
secondTask = secondTask(self.rabbitMq)
</code></pre>
<p>app = App()</p>
<h1>error : 'start_consuming may not be called from the scope of '</h1>
<p>pika.exceptions.RecursionError: start_consuming may not be called from the scope of another BlockingConnection or BlockingChannel callback</p>
<p>I searched for the cause of this Error and obviously is pika not thread safe but there must be a Solution for this. maybe Not using a BlockingConnection ? maybe someone can give me an Example how to do that because i tried it and didnt work. Maybe I'm missing something about how to Implement multithreading with rabbitmq</p>

EditText field in AlertDialog not working
|
<p>I'm new to android, trying to build a simple app involving some simple data input and management. When I follow the guide <a href="http://www.mkyong.com/android/android-prompt-user-input-dialog-example/" rel="nofollow">here</a>, which ask for user input through an alert dialog. Everything works fine except that, after the AlertDialog appears, the <code>EditText</code> field does not have an input cursor displayed, and it won't display/update the text I typed. However, I can obtain the text string I typed in correctly after I pressed the 'OK' button in the alert dialog. Here is the xml file and code involving that dialog:</p>
<p>xml:</p>
<pre><code><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/layout_root"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:padding="10dp" >
<TextView
android:id="@+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Type Your Message : "
android:textAppearance="?android:attr/textAppearanceLarge" />
<EditText
android:id="@+id/grade_in"
android:inputType="text"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</EditText>
</code></pre>
<p></p>
<p>code:</p>
<pre><code>Button grade_in = button;
grade_in.setTag(tag);
grade_in.setOnClickListener(new OnClickListener(){
public void onClick(View btn) {
LayoutInflater inflater = LayoutInflater.from(activity.getApplicationContext());
View prompt_grade_in = inflater.inflate(R.layout.grade_in, null);
final EditText input_field = (EditText)prompt_grade_in.findViewById(R.id.grade_in);
AlertDialog.Builder alertBuilder = new AlertDialog.Builder(activity);
alertBuilder.setView(prompt_grade_in);
alertBuilder.setCancelable(true)
.setPositiveButton("OK",
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
Log.v(null, input_field.getText().toString());
}
})
.setNegativeButton("Cancel",
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
})
.setMessage("Grade for the course:");
AlertDialog alert = alertBuilder.create();
alert.show();
}
});
</code></pre>
<p>I tried adding a TextWatcher but it does not help. Is the version the source of this problem? Because I think I pretty much followed the guide except that I've made some minor changes. Thanks for helping!</p>
<p>p.s. the page containing the button invoke the input dialog is a fragment.</p>
<p><strong>UPDATE:</strong>
The fragment containing the button consists of an <code>ExpandableListView</code>, which is implemented according to this <a href="http://www.vogella.com/tutorials/AndroidListView/article.html#listfragments" rel="nofollow">guide</a> (part 15). And the above code implementing the alert dialog is in a custom adapter class, which create the group item in the list, inside the following function:</p>
<pre><code>public View getGroupView(int groupPosition, boolean isExpanded, View convertView, final ViewGroup parent) {
if (convertView == null) {
convertView = inflater.inflate(R.layout.listrow_group, null);
}
CheckedTextView checkedTextView = (CheckedTextView) convertView.findViewById(R.id.textView1);
course courses = (course) getGroup(groupPosition);
((CheckedTextView) checkedTextView).setText(courses.code + " - " + courses.title);
((CheckedTextView) checkedTextView).setChecked(isExpanded);
String tag = courses.code + " - " + courses.title;
CheckBox checkbox = (CheckBox) convertView.findViewById(R.id.checkbox_course);
checkbox.setChecked(sharedPref.getBoolean(tag, false));
setBoxListener(checkbox, tag);
Button button = (Button) convertView.findViewById(R.id.grade_button);
setBtnListener(button, tag);
return convertView;
}

How to use AES Encryption and Decryption from Scala to Python
|
<p>I have a code in scala where I have my encryption and decryption code, It works fine and the code is:</p>

<p>pwd1: String = #test@12345<br />
#test@12345</p>
<p>I tried in Python to achieve the same but does not give the expected encryption result, here is my code(I took the help of other similar answers):</p>
<pre><code>from hashlib import sha256

<p>b'ZW5jcnlwdGlvbkludFZlY5R4atTszEmJ4/tF8YjcyoU='</p>
<p>As you can see both the encryption is not right, I don't know where I am doing wrong. Please help in achieving the same encrypting result in python as showing in scala, I would be much thankful.</p>

<p>The styleSheet applied is this</p>

ul.SearchResult li ul li a:hover { color:#FF9900; }
</code></pre>
<p>But the side by side alignment is not working at all.
What could be wrong?
h?
P.S: and yeah, I saw <a href="https://stackoverflow.com/questions/93625/float-divs">floating divs in list items</a>
Its DIV mentioned there and ul here. Is "clear:left" applicable for bot?</p>
<p>It may be duplicate post for experts in CSS, but I am not. So please bear with it [:)]</p>
<p>Edit Note:- To explain the stuff in detail heres an image

<p>The main issue...
If I leave out <code>event.stopPropagation</code>, when I run this and click the 'Delete Comment' link, everything works as expected. However, when I add it in, I get the error <code>Uncaught TypeError: Cannot read property 'stopPropagation' of null</code>. I assume the <code>onClick</code> event in the Comment component (see bottom code box), is not passing the event through. Is there any way to rectify this?</p>
<pre><code> _deleteComment(event, key) {
event.stopPropagation()
console.log(key)
this.setState (
{comments: this.state.comments.filter((singleComment) => singleComment.id !== key)
}
)
console.log(this.state.comments)
}
}
</code></pre>
<p>For reference, the Comment component:
I tried binding(this) to <code>onDelete</code> e.g. <code><a className="comment-actions-delete" href="#" onClick={this.props.onDelete.bind(this)}>Delete comment</a></code> but it didn't seem to work.</p>
<pre><code>export default class Comment extends React.Component {

Is there any documentation for xmlseclibs?
|
<p>I have signed the XML but I don't know how to include KeyValue element in the signature. Having some documentation would save a lot of time.</p>
<p>The code below (if you are interested) is what I managed to do with xmlseclibs so far:</p>
<pre><code><?php
require('xmlseclibs.php');
</code></pre>
<p>XML string</p>
<pre><code>$getToken = '<getToken>
<item>
<Semilla>Random string</Semilla>
</item>
</getToken>';
</code></pre>
<p>Creating XML object (to sign)</p>
<pre><code>$getToken_DOMDocument = new DOMDocument();
$getToken_DOMDocument -> loadXml($getToken);
</code></pre>
<p>Creating the signature object with xmlseclibs</p>
<pre><code>$getToken_XMLSecurityDSig = new XMLSecurityDSig();
$getToken_XMLSecurityDSig -> setCanonicalMethod(XMLSecurityDSig::C14N);
</code></pre>
<p>Trying to turn off the ds: prefix which didn't work</p>
<pre><code>$options['prefix'] = '';
$options['prefix_ns'] = '';
$options['force_uri'] = TRUE;
$options['id_name'] = 'ID';
$getToken_XMLSecurityDSig -> addReference($getToken_DOMDocument, XMLSecurityDSig::SHA1, array('http://www.w3.org/2000/09/xmldsig#enveloped-signature', 'http://www.w3.org/TR/2001/REC-xml-c14n-20010315'), $options);
</code></pre>
<p>Accessing the necessary key data</p>
<pre><code>$XMLSecurityKey = new XMLSecurityKey(XMLSecurityKey::RSA_SHA1, array('type'=>'private'));
$XMLSecurityKey -> loadKey('../../DTE/certificado/firma/certificado.pem', TRUE);
/* if key has Passphrase, set it using $objKey -> passphrase = <passphrase> */
</code></pre>
<p>Signing the XML object</p>
<pre><code>$getToken_XMLSecurityDSig -> sign($XMLSecurityKey);
</code></pre>
<p>Adding the public key</p>
<pre><code>$getToken_XMLSecurityDSig -> add509Cert(file_get_contents('../../DTE/certificado/firma/certificado.pem'));
</code></pre>
<p>Appending the enveloped signature to the XML object </p>
<pre><code>$getToken_XMLSecurityDSig -> appendSignature($getToken_DOMDocument -> documentElement);
</code></pre>
<p>Saving the signed XML code toa file</p>
<pre><code>$getToken_DOMDocument -> save('sign-basic-test.xml');
?>
</code></pre>
<p>Additionaly would also like from this library:</p>
<ol>
<li>Know official and trustable repository to ensure the library is not corrupted.</li>
<li>Turning off the "ds:" prefix (because nor the example nor the documentation of the XML I am producing includes such prefix).</li>
<li>Linebreaks every X characters in the Base64 type values.</li>
<li>Full indentation (otherwise none at all).</li>
</ol>
<p>I got the library from <a href="https://code.google.com/p/xmlseclibs/" rel="nofollow">enter link description here</a></p>

Firebase Cloud Functions async function
|
<p>I need some help with async function with firebase and node.js</p>
<p>I have this function in my index.js</p>
<pre><code>const funcBiglietti = require('./biglietti');
//Region biglietti
exports.getBiglietti = functions.https.onRequest((req, res) => {
let userid = req.url.replace('/','');
let utente = admin.database().ref("Utenti").child(userid).once("value");
var userInfo = {};
utente.then(snap =>{
if(snap === undefined)
return res.status(400).send('utente non trovato.');
else
return userInfo = JSON.stringify(snap);
}).catch(err => {
return res.status(500).send('errore:' + err);
})
let tickets = await funcBiglietti.getBiglietti(userInfo,userid,admin.database());
return res.status(200).send(tickets);
});
</code></pre>
<p>instead in biglietti.js i have this function:</p>
<pre><code>///Restituisce tutti i biglietti di un utente
exports.getBiglietti = async function(Utente,IDUtente,database){
console.log('userinfo' + Utente);
const biglietti = database.ref("Biglietti").child(IDUtente).once("value");
biglietti.then(snap =>{
console.log(JSON.stringify(snap));
return snap;
}).catch(err => {
return err;
})
}
</code></pre>
<p>I need the function in index.js to wait the result in biglietti.js but when I'm trying to use the async / await i keep getting:</p>

How to convert this PHP array of objects to json?
|
<p>I have an array of 10 objects that I am trying to convert to JSON. The array is being stored in a variable called <code>$invoices</code>. Below is the ouput of <code>var_dump($invoices)</code> shorted to only the first object.</p>
<p>I've tried the following:</p>
<pre><code>$invoices = json_encode($invoices, FALSE);
$invoices = json_encode($invoices, TRUE);
$invoices = json_encode($invoices, JSON_UNESCAPED_UNICODE);
</code></pre>
<p>However, the output is always:</p>
<pre><code>string(31) "[{},{},{},{},{},{},{},{},{},{}]"
</code></pre>
<p>How can this array be properly converted to JSON?</p>
<p>Note: I am running PHP 5.5.9</p>
<p>Update:</p>
<p>It turns out the problem is due the fact that json_encode won't work with "protected member variables." Is there a way to declare those variables as public if I don't have access to the class that created them?</p>

jQuery Draggable, Droppable, ASP.NET MVC
|
<p>I've been looking through a lot of tutorials on jQuery draggable/droppable, and trying to apply it to ASP.NET MVC, but I am really confused. </p>
<p>Most of the samples I keep finding seem pretty difficult to understand at least where it pertains to where things are wired. I'm basically trying to have a targetable box (a 'roster') and a list of units ('attendees'). The goal is to be able to drag any of the units into the box, and they are added to the roster in the database.</p>
<p>Does anyone know of some simpler samples that might shed some light on how to use this part of jQuery with ASP.NET MVC?</p>
<p>For instance, I've been looking at <a href="http://philderksen.com/2009/06/18/drag-and-drop-categorized-item-list-with-jquery-and-aspnet-mvc-part-1/" rel="nofollow noreferrer">http://philderksen.com/2009/06/18/drag-and-drop-categorized-item-list-with-jquery-and-aspnet-mvc-part-1/</a> and it is pretty neat, but it just doesn't explain what I need. It doesn't make a lot of sense and most of the code is pretty strewn about, and I can't even trace where certain calls are being made to figure out how things are wired. (How is jQuery calling the Controller actions, for instance, to trigger when something is dropped? How do I get the ID of the item being dragged so I can add it to the target?)</p>
<hr>
<p>Here, I made some changes - I apologize for the confusion. It still isn't quite working how I'm trying to get it to. Is it possible to make it not fire events if things are re-arranged in their original list, but only when dropped onto another list?</p>

How to use api_gateway_base_path_mapping with terraform?
|
<p>I'm trying to setup a custom domain name for an api in api gateway on aws. I have setup the api fine using terraform. However when I try to setup the custom domain it fails with the following error.</p>
<p>Error applying plan:</p>
<p>1 error(s) occurred:</p>
<ul>
<li><p>module.BillingMetrics.aws_api_gateway_base_path_mapping.billing: 1 error(s) occurred:</p></li>
<li><p>aws_api_gateway_base_path_mapping.billing: Error creating Gateway base path mapping: Error creating Gateway base path mapping: BadRequestException: Invalid REST API identifier specified

<p>I can see in the terraform log that it does get the correct api_id. But I don't understand why it's saying the rest api identifier is invalid.</p>

<p>Are there any more elements that needed to be configured to have the base_path_mapping apply correctly? Any other hints what I might be doing wrong?</p>
<p>I should also mention I'm on terraform 0.9.7.</p>

How to use mutually exclusive flags in your shell and add an optional argument flag ( stuck with getopts)
|
<p>I am using a standard getopts logic. But I want to how I can make the options I offer- mutually exclusive.
e.g. </p>
<pre><code>shell.sh -a SID
<accepted>
shell.sh -b SID
<accepted>
shell.sh -ab SID
Message- using ab together is the same as running shell.sh without any options supplying just SID . Help usage < ya da ya >
shell.sh
Please enter SID at the minimum. Usage < ya da ya >
shell.sh SID
<accepted>
</code></pre>
<p>I am trying to develop this logic using something like below </p>
<pre><code>while getopts ":a:b:" opt; do
case $opt in
a ) SID="$OPTARG";;
set var=1
b ) SID="$OPTARG";;
set var=2
\?) echo "Invalid option: -"$OPTARG"" >&2
exit 1;;
) echo "Option -"$OPTARG" requires an argument." >&2
exit 1;;
esac
done
If (( val == 1 )) then ; # option a is invoked SID supplied
<stuff>
elif (( val == 2 )) then ; # option b is invoked SID supplied
<stuff>
else # SID supplied but neither a or b is invoked
<stuff>
fi
</code></pre>
<p>How do enforce mutually exclusive flags. I a sure there are more acrobat ways to do it. I think I am missing something commonsense here - and trying to figure that out .
Thx </p>
<pre><code>$ more opt.ksh
die () {
echo "ERROR: $*. Aborting." >&2
return 1
}
var=
while getopts ":a:b:" opt; do
case $opt in
a ) SID="$OPTARG"
[ "$var" = 2 ] && die "Cannot specify option a after specifying option b"
[ "$OPTARG" = b ] && die "Do not specify b as a value for option a"
var=1
;;
b ) SID="$OPTARG"
[ "$var" = 1 ] && die "Cannot specify option b after specifying option a"
[ "$OPTARG" = a ] && die "Do not specify a as a value for option b"
var=2
;;
:) die "Must supply an argument to $OPTARG"
;;
\?) die "Invalid option: -$OPTARG. Abort"
;;
esac
done
shift $(($OPTIND - 1))
[ "$SID" ] || SID=$1
[ "$SID" ] || die "You must, at the minimum, supply SID"
</code></pre>
<p>I am using ksh </p>
<pre><code>$ ps -p $$
PID TTY TIME CMD
1261 pts/45 00:00:00 ksh
</code></pre>
<p>1st time I run it .</p>
<pre><code>$ . opt.ksh -a 123 -b 123 # c0
ERROR: Cannot specify option b after specifying option a. Aborting.
-bash: /home/d1ecom1/gin1: No such file or directory
$ . opt.ksh -ab 123 # c1 should reject "cant use a and b togather. try with a or b"
-nologin: .[25]: shift: 4: bad number
$ . opt.ksh -a -b # c2 same as c1's message
$ . opt.ksh -a -b 123 # c3 same as c1
$ . opt.ksh -a -b 123 # c5
$ . opt.ksh -ab 123 # c6
$ . opt.ksh -a 123 -b 123 # c7
</code></pre>
<p>All above cases C0:C7 should reject. Notice C0 and C7 are the same. Yet inspite of this C0 gives the expected error and C7 will not give any error ? strange </p>
<p>only ones to work should be </p>
<pre><code>. opt.ksh -a 123
. opt.ksh -b 123
. opt.ksh 123
</code></pre>
<p>@hvd :TYSM for your reply.
I would like to add an additonal flag -p that will give a "path override" option.
so maybe we have to extend getopt to take parameters like this </p>
<pre><code> die () {
echo "ERROR: $*. Aborting." >&2
exit 1
}
var=
opta=false
optb=false
while getopts ":ab:p" opt; do
case $opt in
a ) $optb && die "Cannot specify option a after specifying option b"
opta=true
;;
b ) $opta && die "Cannot specify option b after specifying option a"
optb=true
;;
p ) [ -d "$mypath" ] && die "path is invalid"
;;
\?) die "Invalid option: -$OPTARG. Abort"
;;
esac
done
shift $(($OPTIND - 1))
test $# -eq 0 && die "You must supply SID"
test $# -eq 1 || die "Too many command-line arguments"
# SID=$1
</code></pre>
<p>The above was the old approach. Now I have 2 Input parameters. One is the SID and the other is the path. Is it as simple as the above or do I need to add more checks to prevent other unwanted combinations. The question I guess I am trying to aim at is , what more provisions would need to be made to allow this -p parameter which is an optiona override parameter. - p can co-exist with any parameter above but then I guess one requirement is that it should be immediately following the -p flag
so this should not allow - because its not clear .</p>
<pre><code>shell.sh -b -p 123 /home/yadaya
</code></pre>
<p>Thanks again </p>

Azure Key Vault: Secret not found error
|
<p>I've created the Key Vault and entered a secret. When I run my services locally using .NET, I am able to retrieve the secret via the key vault. Here's what I did:
1) Created an SSL certificate
2) Used that SSL certificate to create an AD application
3) Created a Service Principle for the above application
4) Gave full key vault access to this application
5) I put the VaultURI, ServicePrincipal.Application ID, and the cert thumbprint in the Web.config file
6) I also uploaded the *.pfx of that cert to my cloud service</p>
<p>When I run my service locally, I am able to retrieve the secret. I have even tried retrieving the secret via powershell and I have been successful. When I deploy my code to Azure, I am unable to retrieve the secret.</p>
<p>It says:</p>
<pre><code>Type : Microsoft.Azure.KeyVault.Models.KeyVaultErrorException, Microsoft.Azure.KeyVault, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35 Message : Secret not found: QSAccounts7126 Source : Microsoft.Azure.KeyVault Help link :
</code></pre>
<p>I have spent 3 days looking at it and retesting every possible scenario and haven't figured out what is wrong. Can someone please help in identifying the issue or directing me in the right path for debugging?
I even tried publishing the cloud service in debug mode in Azure, and for some reason that did not work either. </p>
<p>Any help you can provide would be greatly appreciated.</p>

How can I run command line FFMPEG and accept multiple pipes (video and audio) without blocking on the first input?
|
<p>I'm trying to mux h264 and aac created with MediaCodec using FFMPEG, and also use FFMPEG's RTMP support to send to youtube. I've created two pipes, and am writing from java (android) through WriteableByteChannels. I can send to one pipe just fine (accepting null audio) like this:</p>
<pre><code>./ffmpeg -f lavfi -i aevalsrc=0 -i "files/camera-test.h264" -acodec aac -vcodec copy -bufsize 512k -f flv "rtmp://a.rtmp.youtube.com/live2/XXXX"
</code></pre>
<p>YouTube streaming works perfectly (but I have no audio). Using two pipes this is my command:</p>
<pre><code>./ffmpeg \
-i "files/camera-test.h264" \
-i "files/audio-test.aac" \
-vcodec copy \
-acodec copy \
-map 0:v:0 -map 1:a:0 \
-f flv "rtmp://a.rtmp.youtube.com/live2/XXXX""
</code></pre>
<p>The pipes are created with mkfifo , and opened from java like this:</p>
<pre><code>pipeWriterVideo = Channels.newChannel(new FileOutputStream(outputFileVideo.toString()));
</code></pre>
<p>The order of execution (for now in my test phase) is creation of the files, starting ffmpeg (through adb shell) and then starting recording which opens the channels. ffmpeg will immediately open the h264 stream and then wait, since it is reading from the pipe the first channel open (for video) will successfully run. When it comes to trying to open the audio the same way, it fails because ffmpeg has not actually started reading from the pipe. I can open a second terminal window and cat the audio file and my app spits out what i hope is encoded aac, but ffmpeg fails, usually just sitting there waiting. Here is the verbose output:</p>

<p>I think if I could just get ffmpeg to start listening to both pipes, the rest would work out!</p>
<p>Thanks for your time.</p>
<p>EDIT:
I've made progress by decoupling the audio pipe connection and encoding, but now as soon as the video stream has been passed it errors on audio. I started a separate thread to create the WriteableByteChannel for audio and it never gets passed the FileOutputStream creation.</p>

Bootstrap fluid grid overlap issues
|
<p>I have been playing with fluid grids for a while now using Twitter Bootstrap, but even in the latest version I am finding it impossible to create a fluid grid without getting overlapping elements. The correct bootstrap css file is included and all the mark up is correct, so I can only assume that this is to do with input fields, but I would have thought the creators of Bootstrap would take this into account?</p>
<p>You can view the code in a fiddle here: <a href="http://jsfiddle.net/pNRzV/1/" rel="nofollow">http://jsfiddle.net/pNRzV/1/</a>
Try re-sizing the content window and you will see the overlapping issues.</p>

<p>Basically, I want to just convert this data into a JSON entity. I want to get this done in <strong>jQuery</strong> and I think I'm having a really tough time doing it. The above list is just an example and in reality, my list would ideally have more number of children and probably be 'n' levels deep (Meaning, it will have grandchildren of grandchildren of grandchildren...or more) I've lost countless hours of sleep on this and I don't think I'm going anywhere :(</p>
<p>I want to extract these things: The text inside the anchor, the url of the anchor and the title of the anchor and put them onto a JSON entity</p>
<p><strong>The JSON format for my list above is something like this:</strong></p>
<pre><code>{
name: "Item A",
url: "url of Item A",
title: "sometitle",
children: [{
name: "Child1 of A",
url: "url of Child1 of A",
title: "sometitle",
children: [{
name: "Grandchild of A",
url: "url of Grandchild of A",
title: "sometitle",
children: [{
name: "Grand Grand child of A",
url: "url of Grand Grand child of A",
title: "sometitle",
children: []
}]
}]
}]
},
{
name: "Item B",
url: "url of Item B",
title: "sometitle",
children: []
},
{
name: "Item C",
url: "url of Item C",
title: "sometitle",
children: []
}
</code></pre>

How to add rows to a RadGridView in WinForms using c#
|
<p>I am trying to add a rows to a RadGridView when a use click a button on the form (ie. "Add".)</p>
<p>When the form load I add columns to the <code>RadGridView</code> and make all of them all ReadOnly except one .</p>
<p>When a user click the "Add" button, I want to add a row to this RadGridView. Basically, a user types a UPC code, then I read data from the database and add new row in a grid view with the item name, item price.</p>
<p>Here is what I did to create the columns</p>
<p>private void Register_Load(object sender, EventArgs e) {</p>
<pre><code> GridViewTextBoxColumn UPC = new GridViewTextBoxColumn();
UPC.Name = "UPC";
UPC.HeaderText = "UPC";
UPC.FieldName = "UPC";
UPC.MaxLength = 50;
UPC.TextAlignment = ContentAlignment.BottomRight;
radGridView1.MasterTemplate.Columns.Add(UPC);
radGridView1.Columns["UPC"].Width = 120;
radGridView1.Columns["UPC"].ReadOnly = true;
GridViewTextBoxColumn ItemName = new GridViewTextBoxColumn();
ItemName.Name = "Item Name";
ItemName.HeaderText = "Item Name";
ItemName.FieldName = "ItemName";
ItemName.MaxLength = 100;
ItemName.TextAlignment = ContentAlignment.BottomRight;
radGridView1.MasterTemplate.Columns.Add(ItemName);
radGridView1.Columns["Item Name"].Width = 210;
radGridView1.Columns["Item Name"].ReadOnly = true;
GridViewDecimalColumn QtyColumn = new GridViewDecimalColumn();
QtyColumn.Name = "Qty";
QtyColumn.HeaderText = "Quantity";
QtyColumn.FieldName = "Qty";
QtyColumn.DecimalPlaces = 1;
radGridView1.MasterTemplate.Columns.Add(QtyColumn);
radGridView1.Columns["Qty"].Width = 75;
GridViewMaskBoxColumn PriceColumn = new GridViewMaskBoxColumn();
PriceColumn.Name = "Unit Price";
PriceColumn.FieldName = "UnitPrice";
PriceColumn.HeaderText = "Unit Price";
PriceColumn.MaskType = MaskType.Numeric;
PriceColumn.Mask = "C";
PriceColumn.TextAlignment = ContentAlignment.BottomRight;
PriceColumn.FormatString = "{0:C}";
PriceColumn.DataType = typeof(decimal);
radGridView1.MasterTemplate.Columns.Add(PriceColumn);
radGridView1.Columns["Unit Price"].Width = 75;
radGridView1.Columns["Unit Price"].ReadOnly = true;
GridViewMaskBoxColumn TotalColumn = new GridViewMaskBoxColumn();
TotalColumn.Name = "Total Price";
TotalColumn.FieldName = "TotalPrice";
TotalColumn.HeaderText = "Total Price";
TotalColumn.MaskType = MaskType.Numeric;
TotalColumn.Mask = "C";
TotalColumn.TextAlignment = ContentAlignment.BottomRight;
TotalColumn.FormatString = "{0:C}";
TotalColumn.DataType = typeof(decimal);
radGridView1.MasterTemplate.Columns.Add(TotalColumn);
radGridView1.Columns["Total Price"].Width = 75;
radGridView1.Columns["Total Price"].ReadOnly = true;
}
</code></pre>
<p>To add the row Here is what I am doing "when a user click the 'Add' button)</p>
<pre><code>private void ButtonAdd_Click(object sender, EventArgs e) {
string UPC = InputUPC.Text.Trim();
if (UPC.Length < 3) {
return;
}
string sql = " SELECT p.productName, p.price "
+ " FROM products AS p "
+ " WHERE p.productUPC = @upc ";
var parms = new List<MySqlParameter>();
parms.Add(new MySqlParameter("@upc", UPC));
var db = new dbConnetion();
foreach (var i in db.getData(sql, parms, r =>
new ProductsTable() {
_productName = r["productName"].ToString(),
_price = Convert.ToDouble(r["price"])
}
)
) {
//radGridView1.Rows[0].Cells[0].Value = 4.3;
radGridView1.Rows[0].Cells["UPC"].Value = UPC;
radGridView1.Rows[0].Cells["Item Name"].Value = i._productName;
radGridView1.Rows[0].Cells["Qty"].Value = "1";
radGridView1.Rows[0].Cells["Unit Price"].Value = i._price;
radGridView1.Rows[0].Cells["Total Price"].Value = (Convert.ToDouble(i._price) * Convert.ToInt32(radGridView1.Rows[0].Cells["Qty"].Value)).ToString();
}
}
</code></pre>
<p>But the add row is giving me an error</p>
<pre><code>Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
</code></pre>
<p>How can I correctly add rows to the RadGridView when the "Add" button is clicked.</p>

<h2>Slide man</h2>
<p>Lorem Ipsum is simply dummy text of the printing and typesetting industry.
Lorem Ipsum has been the industry's standard dummy text ever since the 1500s,
when an unknown printer took a galley of type and scrambled it to make a type specimen
book. It has survived not only five centuries, but also the leap into electronic
typesetting, remaining essentially unchanged. It was popularised in the 1960s with the
release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop
publishing software like Aldus PageMaker including versions of Lorem Ipsum.</p>

<h2>Mafans</h2>
<p>It is a long established fact that a reader will be distracted by the readable
content of a page when looking at its layout. The point of using Lorem Ipsum is
that it has a more-or-less normal distribution of letters, as opposed to using
'Content here, content here', making it look like readable English. Many desktop
publishing packages and web page editors now use Lorem Ipsum as their default
model text, and a search for 'lorem ipsum' will uncover many web sites still in
their infancy. Various versions have evolved over the years, sometimes by accident,
sometimes on purpose.</p>

</code></pre>
<p>This is the jSon array, so I want to build 2 arrays.</p>
<p>1 array holding only keys (in this case the date) of those element where <code>status=='booked' nOR status=='unavailable'</code> and build it in jQuery array like this</p>
<pre><code>var array = ['2015-03-19', '2015-03-20', '2015-03-21', '2015-03-22', '2015-03-23', '2015-03-24', '2015-03-25', '2015-03-26', '2015-04-07', '2015-04-08', '2015-04-09', '2015-04-10'];
</code></pre>
<p>Another is building another array with the dates of those days where <code>status=='available' AND price > '100$'</code></p>
<p>var array2 = [ '2015-03-25', '2015-03-26', '2015-04-07', '2015-04-08'];</p>
<p>How can I achieve this on with jQuery?</p>

<p>Ok so I thought i would put this one out there. I have a list of 25 entries in my db which I would like to display on my page, in list form, in 5 columns with 5 rows. </p>
<p>I prepared a solution, albeit not such an elegant one.</p>
<pre><code><?php
$query = "SELECT * FROM city ORDER BY name ASC";
$result = mysql_query($query, $connection);

Pandas: If statement with multiple conditions on pandas dataframe
|
<p>I am trying to compare rows within a group and if a condition is met within the rows, I want to either keep the complete group, keep the most recent row, or keep the first row. </p>
<p>The dataframe will only have 2 items per group. If the first row of the group has the LastFour digits of '2290' OR if it start with the letter 'M' AND if in the second row the LastFour column is equal to either 0087 OR 0117 AND if NUM != 6708 then I want to keep both rows. This is the first conditional. The second condition is if the rows are the same for each column except for the Date column then keep the row with the most recent date. Else, if neither of these conditions are met, keep the first row only and remove the second row.</p>
<p>Original df:</p>
<pre><code> KEY CLAIM LastFour NUM Date1 Date2 Code

Do i need to install Nvidia's SDK(CUDA) for OpenCL to detect Nvidia GPU?

<p>I have a code written in C (using opencl specs) to list all the available devices. My PC has an AMD FirePro as well as Nvidia's Tesla graphics card installed.

But the following code lists only the CPU and does not detect the 2 graphics card.

How can I get this code for a GUI Countdown Timer to work properly?
|
<p>I'm trying to custom write a program for a GUI Countdown Timer (for a personal project), based on some other codes that I've found on this site. </p>
<p>The idea is that a user will be able to select the total time (variable <code>"remaining"</code>) in mins from a combo box, press <code>"Start"</code>, and the countdown will start.</p>
<p>However, in my current code (below), after selecting the total time from the combo box and pressing <code>"Start"</code>, the label will show the correct start time, but the countdown will not start. If I manually set <code>"remaining"</code> at the top of the code (line 23) to the total time, eg. <code>61000</code> and remove the line <code>"remaining = convertTime();"</code> under my <code>actionPerformed</code> interface, the countdown timer works perfectly fine.</p>
<p>I'm not sure what went wrong.</p>

React-Bootstrap - Pagination not showing

<p>I'm using the react-bootstrap to paginate the result. It is rendering the div #content, but it is not showing nothing more. It is showing only a empty div with width, height and background color as I configured on the CSS file. I would like to display the pagination showing one house per page. The result of data from JSON is catched successfully. How can I solve the pagination issue? Thanks! </p>

Applying AutoNumeric.js to an entire class
|
<p>I would love if someone could help me with what i thought would be a simple application of AutoNumeric.js. I have the below code:</p>
<p>Fiddle link: <a href="https://jsfiddle.net/yu1s9nrv/8/" rel="nofollow noreferrer">https://jsfiddle.net/yu1s9nrv/8/</a> </p>
<pre><code><table id="shareInput" class="table_standard">
<tr>
<th>Name</th>
<th>Quantity</th>
<th>Price</th>
<th>Growth</th>
<th>Yield</th>
</tr>
<tr>
<td><input type="text" class="input_field_large" id="shareName" value=""></td>
<td><input type="text" class="input_field_medium_num" id="shareQty" value=""></td>
<td><input type="text" class="input_field_medium_dollar" id="sharePrice" value=""></td>
<td><input type="text" class="input_field_medium_pct" id="shareGrowth" value=""></td>
<td><input type="text" class="input_field_medium_pct" id="shareYield" value=""></td>
</tr>
<tr>
<td><input type="text" class="input_field_large" id="shareName" value=""></td>
<td><input type="text" class="input_field_medium_num" id="shareQty" value=""></td>
<td><input type="text" class="input_field_medium_dollar" id="sharePrice" value=""></td>
<td><input type="text" class="input_field_medium_pct" id="shareGrowth" value=""></td>
<td><input type="text" class="input_field_medium_pct" id="shareYield" value=""></td>
</tr>
</table>
<script>
window.onload = function() {
const anElement = new AutoNumeric('.input_field_medium_pct', 0, {
suffixText: "%"
});
};
</script>
</code></pre>
<p>The output I expect is for <em>all</em> the fields with the class input_field_medium_pct to have the desired AutoNumeric formatting, however it only formats the first field with that class. The documentation reads:</p>
<blockquote>
<p>// The AutoNumeric constructor class can also accept a string as a css
selector. Under the hood this use <code>QuerySelector</code> and limit itself to
only the first element it finds. anElement = new
AutoNumeric('.myCssClass > input'); anElement = new
AutoNumeric('.myCssClass > input', { options });</p>
</blockquote>
<p>Taken from: <a href="https://github.com/autoNumeric/autoNumeric#initialize-one-autonumeric-object" rel="nofollow noreferrer">https://github.com/autoNumeric/autoNumeric#initialize-one-autonumeric-object</a></p>
<p>I'm new to JS the and find the AutoNumeric documentation notes to be slightly confusing, has anyone run into this issue or able to shed some light on why this might be the case? Thanks in advance.</p>

Convert Microsoft Word equations to Latex

Need a fixed navbar and landing page VH that incorporates navbar height
|
<p>I am working on my first portfolio and running into some trouble doing two things. </p>
<ol>
<li><p>Creating a fixed navbar. When I use position: fixed; it clears my float on the right "Contact Me", and everything collapses. I need this to stay spaced how it is in my example. Searched for quite some hours and I cannot find a fix as of yet, although I am a novice so I am sure that plays into this some as well.</p></li>
<li><p>For my landing page photo, I am trying to make a responsive design that allows it to resize to 100% of the available page size. I had implemented this with height: 100vh; however quickly noticed that it is taking the 100vh, and implementing this after my navbar, which leaves excess below. I tried to compensate by reducing the vh to account for the navbar, but of course I realized that this would not be a good fixed as it would only work for that viewport height, and not scale accordingly.
This leaves me either needing a fix to scale the content appropriately, or allow the photo to slide under the navbar, and occupy that space as well so that it is touching the top of the page.</p></li>
</ol>
<p>Relevant HTML:</p>
<pre><code> <header>
<div class="navbar">
<ul>
<li><a href="#home" class="active">Home</a></li>
<li><a href="#aboutme">About Me</a></li>

PyQT5 and Filtering a Table using multiple columns
|
<p>I am trying to make a <code>PyQt5</code> GUI to show a Pandas dataframe in the form of a table and provide column filtering options, similar to the Microsoft Excel filters. So far I managed to adopt a similar <a href="https://stackoverflow.com/questions/14068823/how-to-create-filters-for-qtableview-in-pyqt">SO answer</a>. Here is the picture of my table in the GUI:</p>
<p><a href="https://i.stack.imgur.com/hazQj.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/hazQj.png" alt="enter image description here"></a></p>
<p>As shown in the figure above, there are two ways to filter columns: the Regex Filter and clicking on each column. There is however a problem I need help to address: the currently applied filters (either regex filter or column click) disappear when I filter a second column. I want the second filter as <code>AND</code>, i.e. a filter that satisfies column 1 <code>AND</code> column 2.</p>

<p>But this code has no error on my Macbook. What's the problem?</p>
<p>Updated: 2020-08-05</p>
<p>I open the debugger and found that every <code>HTTPConnection</code> object have been set the system wide http proxy. But I did not set any options explicitly in my code. And the <code>driver.quit</code> method will send http://localhost:59717/shutdown to chrome to perform quit. So I guess the shutdown url is actually sent to the proxy server, not the local browser.</p>
<p>And I try to use fiddler to check the request informations. There is another problem that I can not decode the https requests because of some certificates configs. So I change the argument of <code>driver.get()</code> to an internal web url of my company. The result is : If I close fiddler, <code>RemoteDisconnected</code> error raise again. And if I open fiddler, all works.</p>
<p>What happened? I know fiddler set the proxy to 127.0.0.1:8888, so I think there could be something wrong with the proxy settings. But I can not fix it. I guess the chrome use the system proxy so the github home page could open correctly, but when send shutdown url to chrome, the request object should not use the system proxy, but it does.</p>
<p>Am I right? And how to fix this problem?</p>

Unity Container Registration with Names are not working while without name works fine
|
<p>I know this sounds stupid. I'll provide some pieces of code and will try to explain as much.</p>
<h3>Implementation #1 - Without name</h3>
<pre><code> Container = new UnityContainer();
Container.RegisterType<IFirstInterface, FirstImplementation>();
Container.RegisterType<IDifferentAssemblyInterface, DifferentAssemblyImplementation>();
Container.RegisterType<ISameAssemblyInterface, SameAssemblyImplementation>();
</code></pre>
<h3>Implementation #2 - With name</h3>
<pre><code>const string configurationName = "simpleOption";
Container = new UnityContainer();
Container.RegisterType<IFirstInterface, FirstImplementation>(configurationName);
Container.RegisterType<IDifferentAssemblyInterface, DifferentAssemblyImplementation>(configurationName);
Container.RegisterType<ISameAssemblyInterface, SameAssemblyImplementation>(configurationName);
</code></pre>
<h3>Observations</h3>
<p>Implementation #1 works just fine. I used the immediate window and everything resolves.</p>
<p>With implementation #2 I used immediate window and everything from the same assembly resolves</p>
<p>Implementation #2 immediate window is not able to resolve exactly the IDifferentAssemblyInterface is not able to resolve</p>
<p>I opened up the Registrations constructor and all the dependencies are </p>
<h3>Questions</h3>
<ol>
<li>Am I using named registration correctly?</li>
<li>Is passing the name as simple as that? Just pass a string while registering and the same string during resolve should work.</li>
<li>How do I debug/resolve this?</li>
</ol>

<p>I've tried test cc numbers, cc numbers set up on paypal's sandbox site. I've tried using the credentials in the demo app provided in rest-api-skd-php-master (the demo works btw).</p>
<p>I can show you my code though it pretty precisely emulates the test case.</p>
<p>The only thing I can think of is that the processing files are buried below www access levels?</p>
<p>If you can clean any info from the error logs I'm all ears. If there's more info you need from me I can provide it.</p>

Authentication fails silently in Symfony2
|
<p>I'm having trouble getting authentication to work but it only appears to happen in very specific circumstances. Authentication is done via a third party API so I've written my own user provider class and inside that class is some code that syncs data between the API and Symfony, as part of that syncing process it determines which roles the user should have.
After doing this it sets up the relationships between the roles and user via a ManyToMany relationship.</p>
<p>The getRoles() method in my User object gets the role objects out of the database and turns it into an array of strings, the role names come from my database and all start with ROLE_.</p>
<p>If I login with an account that should have no extra roles it works fine, but if I login to an account that should have roles I just get sent back to the login screen with no error message.</p>
<p>I've checked the log and saw these entries:</p>
<pre><code>security.INFO: User "test105@example.com" has been authenticated successfully [] []
event.DEBUG: Notified event "security.interactive_login" to listener "Pogo\MyBundle\Listener\LoginListener::onSecurityInteractivelogin". [] []

</code></pre>
<p>I don't understand how it can be authenticated at top, then as soon as it checks the firewall it finds itself with an anonymous token which is why it presumably sends me back to the login screen.</p>
<p>My firewall / access_control settings are:</p>
<pre><code>firewalls:
public:
pattern: /.*
anonymous: true
tessitura_login:
login_path: /account/login
check_path: /secure/login_check
logout:
path: /secure/logout
target: /
access_control:
- { path: ^/secure/.*, role: ROLE_USER }
- { path: ^/admin.*, role: ROLE_ADMIN }
- { path: ^/account/login/?, role: IS_AUTHENTICATED_ANONYMOUSLY }
- { path: /.*, role: IS_AUTHENTICATED_ANONYMOUSLY }
</code></pre>
<p>Any help with this would be massively appreciated, I've spent a few hours on this now and am completely stumped.</p>

Accepting certificates in Java
|
<p>I'm having problems interacting with an HTTPS site via Java. My program uses one URL with an untrusted certificate each time the program runs. This program has to run on more than one system. Currently, I have the following:</p>
<pre><code>public class A{
HostnameVerifier hv = new HostnameVerifier(){
public boolean verify(String urlHostName, SSLSession session){
return true;
}
};
HttpsURLConnection.setDefaultHostnameVerifier(hv);
javax.net.ssl.TrustManager[] trustAllCerts = new javax.net.ssl.TrustManager[1];
javax.net.ssl.TrustManager tm = new miTM();
trustAllCerts[0] = tm;
javax.net.ssl.SSLContext sc = null;
try {
sc = javax.net.ssl.SSLContext.getInstance("SSL");
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
}
try {
sc.init(null, trustAllCerts, null);
} catch (KeyManagementException e) {
e.printStackTrace();
}
javax.net.ssl.HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
}
class miTM implements javax.net.ssl.TrustManager, javax.net.ssl.X509TrustManager{
public java.security.cert.X509Certificate[] getAcceptedIssuers(){
return null;
}
public boolean isServerTrusted(java.security.cert.X509Certificate[] certs){
return true;
}
public boolean isClientTrusted(java.security.cert.X509Certificate[] certs){
return true;
}
public void checkServerTrusted(java.security.cert.X509Certificate[] certs, String authType) throws java.security.cert.CertificateException{
return;
}
public void checkClientTrusted(java.security.cert.X509Certificate[] certs, String authType) throws java.security.cert.CertificateException{
return;
}
}
</code></pre>
<p>With this code, I can perform the following just fine:</p>
<pre><code>URL url = new URL(urlString);
URLConnection cnx = url.openConnection();
cnx.connect();
InputStream ins = cnx.getInputStream();
BufferedReader in = new BufferedReader(new InputStreamReader(ins));
String curline;
while( (curline = in.readLine()) != null ) {
System.out.println(curline);
}
</code></pre>
<p>However, I cannot do the following:</p>
<pre><code>httpClient = new HttpClient();
PostMethod postMethod = null;
int intResult = 0;
postMethod = new PostMethod(authURL);
Enumeration emParams = authParams.propertyNames();
while (emParams.hasMoreElements()) {
String paramName = (String) emParams.nextElement();
String paramValue = authParams.getProperty(paramName);
postMethod.addParameter(paramName, paramValue);
}
intResult = httpClient.executeMethod(postMethod);
postMethod.releaseConnection();
ins.close();
</code></pre>
<p>When executeMethod(postMethod) is executed, I get an SSLHandshakeException, CertPathBuilderException, and so on.</p>
<p>What can I do to remedy this? I'm thinking of either accepting the certificate or just bypassing all certificate validation (as the program runs internally within a private network).</p>
<p>Thanks</p>

External HTTP endpoint in Azure worker role possible?
|
<p>I am trying to host an external facing WCF service on Azure within a worker role. </p>
<p>I have a solution working very nice locally, but when I try to publish it to Azure it goes into an initializing/busy/stopped loop. </p>
<p>The information I've found around the internet says different things:</p>
<p><a href="http://www.theworkflowelement.com/2011/01/worker-role-service-hosting-faq.html" rel="nofollow">http://www.theworkflowelement.com/2011/01/worker-role-service-hosting-faq.html</a> (impossible)</p>
<p><a href="http://code.msdn.microsoft.com/WCF-Azure-Worker-Role-on-b394df49" rel="nofollow">http://code.msdn.microsoft.com/WCF-Azure-Worker-Role-on-b394df49</a> (possible with hack)</p>
<p>Other sources say it's possible, but I don't have the rep to post more than two links. </p>
<p>The last one hangs on busy when I try to publish it. </p>
<p>Anyone know how to do this, or if it really is impossible? It would be very nice to host it in a worker role, so I don't have to use the svc and web.config mess that a web role entails. </p>
<p>This is the code I am using:</p>
<pre><code> [ServiceContract(Namespace = "")]
public interface IMyService
{
[OperationContract]
[WebGet]
string Echo(string s);
}
public class MyService : IMyService

{
}
}

{
var endpoint = RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["HttpsEndpoint"];
var uri = new Uri(endpoint.Protocol + "://" + endpoint.IPEndpoint + "/myservice");
var host = new ServiceHost(typeof(MyService), uri);
host.Credentials.UserNameAuthentication.UserNamePasswordValidationMode = UserNamePasswordValidationMode.Custom;
host.Credentials.UserNameAuthentication.CustomUserNamePasswordValidator = new TestPasswordValidator();
var mexBehavior = new ServiceMetadataBehavior();

var soapBinding = new WSHttpBinding(SecurityMode.TransportWithMessageCredential);
soapBinding.Security.Message.ClientCredentialType = MessageCredentialType.UserName;
host.AddServiceEndpoint(ServiceMetadataBehavior.MexContractName, MetadataExchangeBindings.CreateMexHttpsBinding(), "mex");
host.AddServiceEndpoint(typeof(IMyService), soapBinding, "Soap");
var restBinding = new WebHttpBinding(WebHttpSecurityMode.Transport);
restBinding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Basic;
var restEndpoint = host.AddServiceEndpoint(typeof(IMyService), restBinding, "");
restEndpoint.Behaviors.Add(new WebHttpBehavior { HelpEnabled = true, DefaultOutgoingResponseFormat = WebMessageFormat.Json, AutomaticFormatSelectionEnabled = true, DefaultBodyStyle = WebMessageBodyStyle.WrappedRequest });
host.Open();
}

{

<p>I've been using this setup for a while without complications because my functions are simple (like user/auth, cart, category and products reducers).</p>
<p>But for this app I need to load multiple catalogs from a single endpoint. To achieve this I have created a "catalogs" slice with multiple reducers and a single action which performs the requests and dispatches the reducer depending on the name of the catalog.</p>
<pre><code>const initialState = {
catalogOne: [],
catalogTwo: [],
catalogThree: [],
catalogN: []
}
const catalogsSlice = createSlice({
name: "catalogs",
initialState,
reducers: {
catalogOneRequestSucceeded: (state,action) => {
state.catalogOne = action.payload
},
catalogTwoRequestSucceeded: (state,action) => {
state.catalogTwo = action.payload
},
// ... and so on a reducer for each catalog
}
});
</code></pre>
<p>And then I have the following action which is used to request the endpoint with the name of the catalog and dispatch the reducer:</p>
<pre><code>export const catalogRequest = (catalogName) => async (dispatch, getState) => {
const state = getState();
try {
const rsp = await axios.get(`https://catalogEndpointBase/${catalogName}`, {
headers: {
Authorization: `Bearer ${state.user.accessToken}`,
"Content-Type": "application/json",
},
});
switch (catalogName) {
case "catalogOne":
dispatch(catalogOneRequestSucceeded(rsp.data));
break;
case "catalogTwo":
dispatch(catalogTwoRequestSucceeded(rsp.data));
break;
case "catalogThree":
dispatch(catalogThreeRequestSucceeded(rsp.data));
break;
}
return rsp.data;
} catch (e) {
throw e;
}
};
</code></pre>
<p>So my question now is: how do I dispatch this action multiple times in an "async/await" way so the catalogs are loaded one after the other? and also: am I doing it the right way or is there a better approach to this kind of multiple requests?</p>
<p>I was thinking of something like this, but I don't really know how to accomplish that:</p>
<pre><code> useEffect(() => {
const loadCatalogsAsync = async() => {
try {
await dispatch(catalogRequest("catalogOne"));
await dispatch(catalogRequest("catalogTwo"));
await dispatch(catalogRequest("catalogThree"));
// ... and so on for all my catalogs
} catch ( e ) {
console.error(e);
}
}
loadCatalogsAsync();
}, []);
}
</code></pre>
<p>The goal is to find a best-practice for kind of behavior where the app is required to fetch multiple data when the app is loaded.</p>
<p>Thanks.</p>

RSA key pairs generating using bouncy castle. Making code runnable from java program
|
<p>I am using a Java code that I found that generates a public and a private key via the bouncy castle library. My problem is implementing it into code runnable by my android device. My code does not display the RSA keys like I programmed it to and through most of my troubleshooting I am still unable to make my code do as I ask, although I get no errors. My suspicion is the way I put all of my code into a <code>try</code>/<code>catch</code> block but I am not really sure.
Edit: Lower in code</p>
<p>This is the Java class that generates the RSA public and private key. (It works)</p>
<pre><code>public class ClassMain {
public static void main(String[]args) throws Exception {
String ST = "Ebenezersawesome";
byte[] plainText = "ST".getBytes("UTF8");
// Generating RSA Key
System.out.println("\nStart generating RSA key");
KeyPairGenerator keyGen = KeyPairGenerator.getInstance("RSA");
keyGen.initialize(4096);
KeyPair key = keyGen.generateKeyPair();
System.out.println("Finish generating RSA key");
//
// Creates an RSA Cipher object (specifying the algorithm, mode, and
// padding).
Cipher cipher = Cipher.getInstance("RSA/ECB/PKCS1Padding");
//
// Print the provider information
System.out.println("\n" + cipher.getProvider().getInfo());
System.out.println("\nStart encryption");
//
// Initializes the Cipher object.
cipher.init(Cipher.ENCRYPT_MODE, key.getPublic());
//
// Encrypt the plaintext using the public key
byte[] cipherText = cipher.doFinal(plainText);
System.out.println("Finish encryption: ");
System.out.println(new String(cipherText, "UTF8"));
System.out.println("\nStart decryption");
//
// Initializes the Cipher object.
cipher.init(Cipher.DECRYPT_MODE, key.getPrivate());
//
// Decrypt the ciphertext using the private key
byte[] newPlainText = cipher.doFinal(cipherText);
System.out.println("Finish decryption: ");
System.out.println(new String(newPlainText, "UTF8"));
}
}
</code></pre>
<p>This is my attempt at trying to display the code in an android application.
Edit: The code works but for some reason my try/catch stops and does not generate code in tv3.</p>
<pre><code> TextView tv1;

Button convert;
String publicKeyFilename = null;
String privateKeyFilename = null;
String ST = "Ebenezersawesome";
@Override public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Log.d("Ebz", "Made it to onCreate");
tv1 = (TextView) findViewById(R.id.tv1);
tv2 = (TextView) findViewById(R.id.tv2);
tv3 = (TextView) findViewById(R.id.tv3);
convert = (Button) findViewById(R.id.button1);
// tv2.setText(ST);
convert.setOnClickListener(new OnClickListener() {
public void onClick(View v) {

KeyPair key = keyGen.generateKeyPair();
Cipher cipher = Cipher.getInstance("RSA/ECB/PKCS1Padding");
tv1.setText(cipher.getProvider().getInfo().toString());
Log.d("Ebz", "Made it passed tv1");
//tv1.setText(ST);

// tv2.setText(ST);
byte[] newPlainText = cipher.doFinal(cipherText);
//tv3.setText(new String(newPlainText, "UTF8").toString());
// tv3.setText(ST);
Log.d("Ebz", "Made it passed tv3");
} catch (Exception e) {
System.out.println("error");
}
}
});
}

Using Stanford CoreNLP - Java heap space
|
<p>I am trying to use the coreference module of the Stanford CoreNLP pipeline, but I end up getting an OutOfMemory error in Java. I already increased the heap size (via Run->Run Configurations->VM Arguments in Eclipse) and set them to -Xmx3g -Xms1g. I even tried -Xmx12g -Xms4g, but that didn't help either. I'm using Eclipse Juno on OS X 10.8.5 with Java 1.6 on a 64-bit machine.
Does anyone have an idea what else I could try?</p>
<p>I'm using the example code from the website (<a href="http://nlp.stanford.edu/software/corenlp.shtml" rel="noreferrer">http://nlp.stanford.edu/software/corenlp.shtml</a>):</p>
<pre><code>Properties props = new Properties();
props.put("annotators", "tokenize, ssplit, pos, lemma, ner, parse, dcoref");
StanfordCoreNLP pipeline = new StanfordCoreNLP(props);
String text = "Stanford University is located in California. It is a great university";
Annotation document = new Annotation(text);
pipeline.annotate(document);
List<CoreMap> sentences = document.get(SentencesAnnotation.class);
for(CoreMap sentence: sentences) {
for (CoreLabel token: sentence.get(TokensAnnotation.class)) {
String word = token.get(TextAnnotation.class);
String pos = token.get(PartOfSpeechAnnotation.class);
String ne = token.get(NamedEntityTagAnnotation.class);
}
Tree tree = sentence.get(TreeAnnotation.class);
SemanticGraph dependencies = sentence.get(CollapsedCCProcessedDependenciesAnnotation.class);
}
Map<Integer, CorefChain> graph = document.get(CorefChainAnnotation.class);

Find peak (regions) in 2D data
|
<p>I am looking to find <strong>peak regions</strong> in 2D data (if you will, grayscale images or 2D landscapes, created through a Hough transform). By <em>peak region</em> I mean a <strong>locally maximal peak</strong>, yet <strong><em>NOT a single point</em></strong> but a part of the surrounding <strong><em>contributing region</em></strong> that goes with it. I know, this is a vague definition, but maybe the word <em>mountain</em> or the images below will give you an intuition of what I mean. </p>
<p>The peaks marked in red (1-4) are what I want, the ones in pink (5-6) examples for the "grey zone", where it would be okay if those smaller peaks are not found but also okay if they are.</p>
<p><a href="https://i.stack.imgur.com/HdXT8.png" rel="noreferrer"><img src="https://i.stack.imgur.com/HdXT8.png" alt="an optimal result in 3D"></a></p>
<p>Images contain between 1-20 peaked regions, different in height. The 2D data for above surf plot is shown below with a possible result (orange corresponds to Peak 1, green corresponds to Peak 2 a/b, ...). Single images for tests can be found in the description links:</p>
<p><em>Image left</em>: <a href="https://i.stack.imgur.com/udIuy.png" rel="noreferrer">input image</a> - - - - <em>middle:</em> (okaish) <a href="https://i.stack.imgur.com/4GYrI.png" rel="noreferrer">result</a> - - - - <em>right</em>: result overlayed over image.</p>
<p><a href="https://i.stack.imgur.com/vdOqO.png" rel="noreferrer"><img src="https://i.stack.imgur.com/vdOqO.png" alt="input, result and overlayed result"></a></p>
<p>The result above was produced using simple thresholding (MATLAB code):</p>
<pre><code>% thresh_scale = 15; % parameter: how many thresholding steps
% thresh_perc = 6; % parameter: threshold at which we clip
thresh = multithresh(H,thresh_scale);
q_image = imquantize(H, thresh);
q_image(q_image <= thresh_perc) = 0; % regions under threshold are thrown away
q_image(q_image > thresh_perc) = 1; % ... while all others are preserved
q_image = imbinarize(q_image); % binarize for further processing
B = bwareaopen(q_image, nhood_minsize); % Filter really small regions
[L, L_num] = bwlabel(B); % <- result % Label connected components
</code></pre>
<p>Some values like these (15 and 6) often work fine if there are few similar peaks, but this isn't consistent if more peaks are present or they vary a lot. I mainly have two problems, that also can't be fixed by simply adjusting the parameters:</p>
<ul>
<li>higher peaks can mask lower (but clearly distinguishable) peaks. Since the threshold is relative to the highest peak, other peaks may fall below.</li>
<li>in some cases the valley between two peaks is above the threshold, merging several peaks into one (as can be observed with Peak 2 a/b). </li>
</ul>
<p>I also don't want a huge region for a high peak, so the <em>peak region</em> should probably be defined as some percentage of the mountain. I figured instead of a global thresholding, I'd rather have a method that finds peak regions relative to their immediate environment. I've looked into mean-shift and MSER segmentation, but those seem to be suited for segmenting real images, not kind of synthetic data. </p>
<p>Somehow I imagined filling a negative of the landscape with a certain amount of water would give me the regions I'm looking for: basins that fill and spread with how the surrounding regions are shaped. Like pouring water over below image and the resulting waterpools are the regions I'm looking for. </p>
<p><a href="https://i.stack.imgur.com/sgPqv.png" rel="noreferrer"><img src="https://i.stack.imgur.com/sgPqv.png" alt="negative image (complement), ready to pour water into it"></a></p>
<p>I thought that is what the floodfill or watershed algorithm do, but floodfill seems like something completely else and the watershed results are not at all what I had in mind, also when applying some preprocessing that I thought could help (clipped at 1/10):</p>
<p><a href="https://i.stack.imgur.com/d99c0.png" rel="noreferrer"><img src="https://i.stack.imgur.com/d99c0.png" alt="watershed clipped with threshold 1/10"></a></p>
<p>Or when using the same clipping threshold as with above example (clipped at 6/15):</p>
<p><a href="https://i.stack.imgur.com/Qhfuv.png" rel="noreferrer"><img src="https://i.stack.imgur.com/Qhfuv.png" alt="watershed clipped with threshold 6/15"></a></p>
<p>Produced with this code (MATLAB):</p>
<pre><code>thresh = multithresh(H, 10); % set to either 10 || 15 for the examples
q_image = imquantize(H, thresh);
mask = false(size(q_image)); % create clipping mask...
mask(q_image > 1) = true; % ... to remove lowest 10% || lowest 6/15
% show with: figure, imshow(mask);
% OPTIONAL: Gaussian smoothing
H = imgaussfilt(H, 2); % apply before adding Inf values
% OPTIONAL: H-minima transform
H = imhmin(H, 10); % parameter is threshold for suppressing shallow minima
H = -H; % Complement the image
H(~mask) = Inf; % force "ground" pixels to Inf
L = watershed(D);
L(~mask) = 0; % clip "ground" from result
imshow(label2rgb(L,'lines',[.5 .5 .5])); % show result
</code></pre>
<hr>
<p><strong><em>My question now:</em></strong> <strong>Is there an algorithm that fills a landscape and gives me the resulting waterpools (for various amounts of water poured) to do what I've tried to achieve with above methods?</strong> Or any other suggestion is welcome. I'm implementing MATLAB (or if need be Python), but I can work with any code or pseude-code.</p>
<p>To distinguish this from <a href="https://stackoverflow.com/questions/9587173/algorithm-to-find-peaks-in-2d-array">this question</a>, my maxima are not separated by zero-values. What I want is similar, yet none of the suggestions there are helpful (hill-climbing/simulated annealing will give you only one point...).</p>
<p><a href="https://stackoverflow.com/questions/3684484/peak-detection-in-a-2d-array">This question</a> is also interesting, but it solves the problem with constraints (assume exactly 5 peaks of a certain size) that make the suggested approaches not useful for my case.</p>

CSS3 animate only on hover on and off
|
<p>I have an animation of a box, where it's width increases on hover:</p>
<p>JSFiddle: <a href="https://jsfiddle.net/hbpncv34/" rel="nofollow noreferrer">https://jsfiddle.net/hbpncv34/</a></p>
<p>HTML:</p>
<pre><code><div></div>
</code></pre>
<p>CSS:</p>
<pre><code>div {

}
div:hover {
animation: change_width 0.7s forwards;
}
@keyframes change_width {
from {
width: 10vw;
}
to {
width: 15vw;
}
}
</code></pre>
<p><strong>Issue:</strong></p>
<p>I also want the box to smoothly move back when I hover off of it.</p>
<p>There are two ways I could do this:</p>
<h3>Method 1:</h3>

</code></pre>
<p><strong>Issue:</strong></p>
<p>The animation also runs on zooming in and out.</p>
<p>I can fix this by using <code>px</code> or <code>%</code> instead of <code>vw</code> for my widths, but it's crucial in my actual issue that I keep it as viewport units.</p>
<p>So, is there any way to play an animation on hover on and off, and <strong>only</strong> hover on and off?</p>
<p>Since I don't know Javascript, please keep answers HTML / CSS only. If JS is <em>absolutely needed</em>, make it simple enough to just copy + paste with minimal editing.</p>
<p>Thanks for any help.</p>

sqlite foreach in select statement?
|
<p>I have got a problem with an SQLite select.</p>
<p>There are the tables "kategorie","lv","majetok","parcela".</p>
<p>Each person has information about what he owns in the table "majetok". The sample record:</p>
<pre><code>id idpodfk idlvfk podiel podield cislozlv datum1 datum2
1 31 1 1/10000 0,0001 789 16. 9. 2012 16. 9. 2012
</code></pre>
<p>idpodfk-fk of person id<br>
idlvfk-fk of land record id</p>
<p>There is also table LV (table of land records), sample record:</p>
<pre><code>idlv lvnazov katuzemie
1 1830 Plavecký Mikuláš
</code></pre>
<p>Also I use the table "parcela", I store in there information about parcels in the land record</p>
<pre><code>pnazov rozloha idlvfk idkategoriafk typ
5432 692312 1 1 C
</code></pre>
<p>And table kategorie</p>
<pre><code>idkategoria meno
1 Lesné pozemky
</code></pre>
<hr>
<p>What I need:
a foreach record in this select</p>
<pre><code>SELECT SUM(podield) AS sum1, idlvfk
FROM majetok a
WHERE idpodfk = 1
GROUP BY idlvfk
</code></pre>
<p>I need to select this</p>
<pre><code>SELECT SUM(par.rozloha)*sum1 AS m2, kat.meno --sum1 from statement above
FROM Parcela par
INNER JOIN kategorie kat ON par.IDkategoriaFK = kat.IDkategoria
WHERE par.IDLVFK = 1 --IDLVFK from statement above
GROUP BY kat.meno
</code></pre>
<p>The (second's) query output should look like this</p>
<pre><code>m2 kat.meno
123.23 Lesne pozemky --FOR FIRST IDLVFK
324.52 Ostatne pozemky --FOR FIRST IDLVFK
235 Pasienky --FOR FIRST IDLVFK
144.23 Lesne pozemky --FOR NEXT IDLVFK
543.52 Ostatne pozemky --FOR NEXT IDLVFK
756 Pasienky --FOR NEXT IDLVFK
.
.
.
</code></pre>
<p>And then I need to group by kat.meno so the final output should look like this:</p>
<pre><code>m2 kat.meno
267,46 Lesne pozemky
868,04 Ostatne pozemky
991 Pasienky
. --other kat.meno if there is
. --other kat.meno if there is
</code></pre>
<p>Is this possible in one query or do I need to process it on a front-end?</p>
<p>Tables and query background:</p>
<p>There are some parcels in land record (every parcel has its own category, eg forest parcel etc). Person owns a part of a land record (saved in table majetok, eg: 1/1000). That mean he owns 1/1000 from each parcel in that land record. I want to select the area (column "rozloha" in parcela table) that he owns for each category (SUM(par.rozloha)*sum1 AS m2). So we must count sum of all parcels in that category on that land record and multiply with part that owns that person. But he can own 1/1000 on one land record and 3/3456 on the second land record (another land record=another parcels) so we have to do for each land record and that summarize you can see in last code.</p>

dynamically create object tags in javascript

<p>I am wondering why the following code does not create two of my activex object. When the object tag is directly in the HTML it works fine, but for the life of me I can't dynamically create the object item. Is this a security issue or something? I am finding a difficult time finding documentation on this problem. </p>

Upgrading React-Router and replacing hashHistory with browserHistory
|
<p>I have a bootstrap+react theme that was using react-router 1.x and hashHistory and I wanted to remove the hash so followed this <a href="https://stackoverflow.com/questions/25086832/how-to-stop-in-browser-with-react-router">advice</a>.
Initially I tried to do this while having the 1.x version and I was unable to do it so I've decided to upgrade react-router to 2.x.
After installing react-router 2.x the app worked because it was still using hashHistory but when I replaced it with browserHistory:</p>
<ul>
<li>it showed a grey screen</li>
<li>the HTML of the app had only the <code><noscript data-reactid=".0"></noscript></code> tag inside it</li>
<li>the React Developer Tools showed me that the router had a <code>null</code> inside it</li>
<li>I also checked the Network tab and all files were downloaded properly, and had the right content</li>
<li><p><strong>surprisingly the was nothing printed in the JavaScript Console, no error/no warnging</strong> (I'm really shocked about this, but I'm new React, I would like to know what to do in situations like this).
Here are my changes to <code>Router.jsx</code>:</p>
<pre><code> import React from 'react'
import {render} from 'react-dom'
-import {Router} from 'react-router'
+// import {Router} from 'react-router'
+import { Router, Route, Link, browserHistory } from 'react-router'
+// import { useRouterHistory } from 'react-router'
+// import { createHashHistory } from 'history'
+// import { createBrowserHistory } from 'history'`
import History from '../components/layout/navigation/classes/History.js';
import Routes from './Routes.jsx';
+// const appHistory = useRouterHistory(createHashHistory)({ queryKey: false })
+
var rootInstance = render((
- <Router history={History}>
+ <Router history={browserHistory}>
{Routes}
</Router>
), document.getElementById('smartadmin-root'));`
</code></pre></li>
</ul>
<p>The backend uses the <a href="http://www.phoenixframework.org/" rel="nofollow noreferrer">Phoenix Framework</a>.</p>
<p><strong>Later Edit</strong>:
Here you have the <code>hashHistory</code> version that works</p>
<p><a href="https://gitlab.com/blockbuster/react-router-2-with-hash-working-public/tree/master" rel="nofollow noreferrer">https://gitlab.com/blockbuster/react-router-2-with-hash-working/tree/master</a></p>
<p>And here is the <code>browserHistory</code> version that doesn't:</p>
<p><a href="https://gitlab.com/blockbuster/react-router-2-with-browserHistory-not-working-public/tree/master" rel="nofollow noreferrer">https://gitlab.com/blockbuster/react-router-2-with-browserHistory-not-working/tree/master</a></p>
<p>The react code for both can be found under the <code>src</code> directory.</p>
<p>To run the app you need to have <code>Elixir</code>, <code>Phoenix</code> and Postgresql installed, to get backend dependencies( run <code>$ mix deps.get</code>), get frontend dependecies( <code>npm install</code> and <code>bower install</code>), to change the database username and password in <code>config/dev.exs</code>, to create and migrate the database <code>mix ecto.create && mix ecto.migrate</code> and finally run <code>mix phoenix.server</code>.</p>

want to show print preview
|
<p>I want to show a print preview, so I chose to use <a href="https://github.com/etimbo/jquery-print-preview-plugin" rel="nofollow noreferrer">this plugin</a>.</p>
<p>I have added it to my code:</p>
<pre><code><%@ Page language="c#" AutoEventWireup="false" Inherits="System.Web.UI.Page" %>
<%@ Register TagPrefix="CP" TagName="TitleBar" Src="WebUserControl.ascx" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >
<html>
<head>
<title>MyPage</title>
<link href="css/print-preview.css" rel="stylesheet" type="text/css" />
<link rel="stylesheet" href="css/print.css" type="text/css" media="print" />
<script type="text/javascript" src="jquery.tools.min.js"></script>
<script src="jquery.print-preview.js" type="text/javascript" charset="utf-8"></script>
<script type="text/javascript">
$(function () {
/*
* Initialise print preview plugin
*/
// Add link for print preview and intialise
$('#aside').prepend('<a class="print-preview">Print this page</a>');
$('a.print-preview').printPreview();
// Add keybinding (not recommended for production use)
$(document).bind('keydown', function (e) {
var code = (e.keyCode ? e.keyCode : e.which);
if (code == 80 && !$('#print-modal').length) {
$.printPreview.loadPrintPreview();
return false;
}
});
});
</script>
</head>
<body>
<form id="form1" runat="server">
<CP:TitleBar Title="User Control Test" TextColor="green" Padding="10" runat="server" />
<div id="aside"></div>
</form>
</body>
</html>
</code></pre>
<p>In <code>UserControl</code> I did this:</p>
<pre><code><%@ Control Language="C#" AutoEventWireup="true" CodeFile="WebUserControl.ascx.cs" Inherits="WebUserControl" %>
<script src="jquery-1.7.2.min.js" type="text/javascript"></script>
<script type="text/javascript" language="javascript">
$(document).ready(function () {
$("p").text("The DOM is now loaded and can be manipulated.");
});
</script>
<p>Not loaded yet.</p>
<table>
<tr>
<td>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</td>
</tr>
</table>
</code></pre>
<p>Problem is, when I add the script in <code>UserControl</code>, the <code>Print-Preview-Plugin</code> is not working.</p>
<p>When I remove the script from the <code>UserControl</code> the <code>print-preview-plugin</code> works fine.</p>
<p>My question is, why is the plugin not working when I add script to the UserControl? How should I call the Print Preview Plugin file code?</p>

BroadcastReceiver for Incoming calls in android doesn't work

<pre><code>$tmp=$products[0]['design_file'];

<p>It gives me <strong>Null</strong>.
How can I get my array back from that mess?</p>

<p>Read in Php </p>
<pre><code>if (isset($this->request->post['option'])) {

<p>I had some debug and some test... <strong>Then i moved to 3.2.13</strong> version of active record, and all worked as expected. I didn't find any docs for 3.2.18 version...</p>
<p>I don't mind to use 3.2.13 version, but I got curious about that. </p>

Heroku on Rails - Invalid DATABASE_URL

<p>EDIT: The general advice is to use <strong>CEDAR</strong> stack.</p>
<p>Pretty new to RoR, Gems, Heroku and Git. Following tutorial: <a href="http://ruby.railstutorial.org/book/ruby-on-rails-tutorial" rel="nofollow noreferrer">http://ruby.railstutorial.org/book/ruby-on-rails-tutorial</a></p>
<p>Works smoothly on localhost, when deployed to Heroku got <strong>ConnectionNotEstablished error</strong>, that was solved here:

Gradle: Call ant from a custom task
|
<p>I am new to gradle and trying to migrate our currently Maven based automated JAX-WS client building project, as gradle seems to provide an easier way for us to configure the builds for new projects.</p>
<p>I followed this tutorial <a href="http://jaxenter.com/tutorial-gradle-soap-features-revealed-42757-2.html" rel="nofollow">here</a> and was able to generate the client classes for a WSDL endpoint. What I want to achieve now is to put the Task definition in a new DefaultTask class to keep the build.gradle file cleaner, so I created the following file, put it in a new Groovy project and made it available to my build:</p>
<pre><code>class WsimportTask extends DefaultTask {
def List<String> wsdlUrls
@OutputDirectory
File destDir
@TaskAction
def wsimport() {
wsdlUrls.each() {
println "run wsimport for "+ it
ant {
sourceSets.main.output.classesDir.mkdirs()
destDir.mkdirs()
taskdef(name:'wsimport',
classname:'com.sun.tools.ws.ant.WsImport',
classpath:configurations.jaxws.asPath)
wsimport(keep:true,
destdir: sourceSets.main.output.classesDir,
sourcedestdir: destDir,
wsdl: it)
}
}
}
}
</code></pre>
<p>As I want to come up with one single project that contains a subproject for each web service client that we have, I altered the build.gradle file of the main project and added:</p>
<p><strong>main build.gradle</strong></p>
<pre><code>subprojects {
configurations {
wsimport
}
dependencies {
wsimport group: 'com.mycompany.gradle', name: 'tasks', version: '0.0.2-SNAPSHOT'
}
task wsimport(type: com.mycompany.gradle.WsimportTask) {
destDir = file("${buildDir}/generated")
}
compileJava.dependsOn(wsimport)
}
</code></pre>
<p>The subprojects itself should then only need to contain the following configuration:</p>
<p><strong>subproject build.gradle</strong></p>
<pre><code>buildscript {
wsimport {
wsdlUrls = [
"http://...endpoint1.wsdl",
"http://...endpoint2.wsdl"
]
}

<p>On running gradle clean build on the main project, I get the following messages and Exception: </p>
<pre><code>:clean UP-TO-DATE
:Subproject:clean
:Subproject:wsimport
run wsimportfor http://endpoint1.wsdl
:Subproject:wsimport
* Exception is:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':Subproject:wsimport'.
....
FAILED Caused by: org.gradle.api.internal.MissingMethodException: Could not find method ant() for arguments [com.mycompany.gradle.WsimportTask$_wsimport_closure1_closure2@16caac05] on task ':Subproject:wsimport'.
</code></pre>
<p>So gradle understands my configuration, applies the WSDL endpoint and calls my custom task. Then ant {} is evaluated to a local method call the method ant(), which doesn't exist. This makes perfect sense to me, but how can I achieve my goal of calling the actual ant wsimport task from within this custom gradle task?</p>
<hr>
<p><strong>Solution</strong> Thanks Peter for your answer. I think i do start to understand how the Task is getting wired into my build script. I paste the complete Task for future strugglers, as I don't think the whole process of creating such a task (especially the first time) is somewhat inscrutable:</p>
<pre><code>class WsimportTask extends DefaultTask {
def List<String> wsdlUrls
@OutputDirectory
File outDir
@TaskAction
def wsimport() {
wsdlUrls.each() {
def temp = it
println "run wsimport for "+ temp
project.sourceSets.main.output.classesDir.mkdirs()
outDir.mkdirs()
def classpath = project.configurations.jaxws.asPath
def destDir = project.sourceSets.main.output.classesDir
project.ant {
taskdef(name:'wsimport',
classname:'com.sun.tools.ws.ant.WsImport',
classpath:classpath)
wsimport(keep:true,
destdir: destDir,
sourcedestdir: outDir,
wsdl: temp)
}
}
}
}
</code></pre>
<p>Also notable is the fact that the task must not be defined within the buildscipt block of the build.gradle file, like Peter pointed out</p>

sendto: Network unreachable
|
<p>I have two machines I'm testing my code on, one works fine, the other I'm having some problems and I don't know why it is.</p>
<p>I'm using an object (C++) for the networking part of my project. On the server side, I do this: (error checking removed for clarity)</p>
<pre><code> res = getaddrinfo(NULL, port, &hints, &server)) < 0
for(p=server; p!=NULL; p=p->ai_next){
fd = socket(p->ai_family, p->ai_socktype, p->ai_protocol);
if(fd<0){
continue;
}
if(bind(fd, p->ai_addr, p->ai_addrlen)<0){
close(fd);
continue;
}
break;
}
</code></pre>
<p>This all works. I then make an object with this constructor</p>
<pre><code>net::net(int fd, struct sockaddr *other, socklen_t *other_len){
int counter;
this->fd = fd;
if(other != NULL){
this->other.sa_family = other->sa_family;
for(counter=0;counter<13;counter++)
this->other.sa_data[counter]=other->sa_data[counter];
}
else
cerr << "Networking error" << endl;
this->other_len = *other_len;
}
void net::gsend(string s){
if(sendto(this->fd, s.c_str(), s.size()+1, 0, &(this->other), this->other_len)<0){
cerr << "Error Sending, " << s << endl;
cerr << strerror(errno) << endl;
}
return;
}
string net::grecv(){
stringstream ss;
string s;
char buf[BUFSIZE];
buf[BUFSIZE-1] = '\0';
if(recvfrom(this->fd, buf, BUFSIZE-1, 0, &(this->other), &(this->other_len))<0){
cerr << "Error Recieving\n";
cerr << strerror(errno) << endl;
}
// convert to c++ string and if there are multiple trailing ';' remove them
ss << buf;
s=ss.str();
while(s.find(";;", s.size()-2) != string::npos)
s.erase(s.size()-1,1);
return s;
}
</code></pre>
<p>So my problem is, is that on one machine, everything works fine. On another, everything works fine until I call my server's gsend() function. In which I get a "Error: Network Unreachable." I call gercv() first before calling gsend() too. Can anyone help me? I would really appreciate it.</p>
<p>SOLUTION</p>
<p>It turns out that the server didn't like the way I set up the initial sockaddr structure. I was doing this:</p>
<pre><code> struct addrinfo hints;
memset(&hints, 0, sizeof(struct addrinfo));
hints.ai_family = AF_UNSPEC;
hints.ai_socktype = SOCK_DGRAM;
hints.ai_flags = AI_PASSIVE;
hints.ai_protocol = IPPROTO_UDP;
</code></pre>
<p>When it should have been like this</p>
<pre><code> struct addrinfo hints;
memset(&hints, 0, sizeof(struct addrinfo));
hints.ai_family = AF_UNSPEC;
hints.ai_socktype = SOCK_DGRAM;
</code></pre>
<p>Can anyone explain this?</p>

is there difference between dependencies and dependencies in plugin tags?
|
<p>I have a question.</p>
<p>In pom.xml, dependency is included in two places.
one place can be in <code><project></code> tag and the other place can be in <code><plugin></code> tag.</p>
<p>I think the dependencies in tags is just related with the plugin?
is it correct?</p>
<p>thanks in advance :)</p>

Javascript function from external file not working

<p>I'm new to programming and currently learning javascript. I'm trying to test what I've learned so far using a payroll calculator, but my code is not working. I created a function that will be called when the user clicks a button; if I add the function inside the same HTML file, it works fine. When the function is in my external javascript file, the function doesn't work. I clicked on <em>View Page Source</em> to confirm the external javascript file was loaded and it was.</p>

ASP.NET MVC Form - What is the proper way to return to a view with the previous form values?
|
<p>I had an assignment to implement a WCF Service and call it from a client of any type. I already have some experience with console, winform, WPF apps, so I wanted to use this as a chance to learn ASP.NET MVC. </p>
<p>I know that I'm not properly implementing the "M" part of it yet, but I'm wondering what the correct way of processing data on a form in order to update show a result would be instead of what I have (working) so far:</p>
<p>View:</p>
<pre><code>@using (Html.BeginForm("UseSimpleMathClient", "Home"))
{
<div style="width:450px">
<table style="width:100%">
<tr><td><h4>@Html.Label("First number", new { @for = "num1" })</h4></td> <td> @Html.TextBox("num1", ViewData["num1"])</td></tr>
<tr><td><h4>@Html.Label("Second number", new { @for = "num2" })</h4></td> <td> @Html.TextBox("num2", ViewData["num2"])</td></tr>
<tr>
<td colspan="2">
<h2 style="text-align:center">
<input type="submit" name="operation" value="+" />
<input type="submit" name="operation" value="-" />
<input type="submit" name="operation" value="*" />
<input type="submit" name="operation" value="÷" />
</h2>
</td>
</tr>
<tr>
<td colspan="2"><b>@Html.Label("Result")</b> &nbsp; @Html.TextBox("result", ViewData["result"], new {disabled = "disabled", style="min-width:80%;text-align:center" })</td>
</tr>
</table>
</div>
}
</code></pre>
<p>Controller:</p>
<pre><code> public ActionResult USeSimpleMathClient(char operation)
{
float num1, num2;
float? result = null;
if (!float.TryParse(Request.Form[0], out num1) || !float.TryParse(Request.Form[1], out num2))
{
ViewData["result"] = "Please enter valid numbers before selecting an operation.";
}
else
{
switch (operation)
{
case '+':
result = mathClient.Add(num1, num2);
break;
case '-':
result = mathClient.Subtract(num1, num2);
break;
case '*':
result = mathClient.Multiply(num1, num2);
break;
case '÷':
if (num2 != 0)
result = mathClient.Divide(num1, num2);
break;
default:
break;
}
ViewData["result"] = result != null ? String.Format("{0} {1} {2} = {3}", num1, operation, num2, result) : "You can't divide by zero!";
}
ViewData["num1"] = Request.Form[0];
ViewData["num2"] = Request.Form[1];
return View("Index");

e2e testing in angularjs for page navigation

<p>I am writing e2e tests for my web app and stuck at the very beginning. I would appreciate any help to kick start my testing experience.</p>

Detecting and Removing Vertical and Horizontal Lines in OpenCV
|
<p>I'm trying to remove the square boxes(vertical and horizontal lines) from a filled out form using opencv (Python). I am trying to detect the vertical and horizontal lines through morphological operations of OpenCV. <a href="https://i.stack.imgur.com/SkY8h.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/SkY8h.jpg" alt="The original image"></a></p>

<p>Vertical Lines <a href="https://i.stack.imgur.com/JynnN.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/JynnN.jpg" alt="result of vertical lines "></a></p>
<p>After the horizontal and vertical lines are detected , i am simply adding them and subtracting it from processed image.
<code>res = verticle_lines_img + horizontal_lines_img</code>
<code>exp = img_bin - res</code></p>
<p>The final results is not so smoothed as expected.

<p>What could be a novel way to detect and remove the square boxes?</p>

Using Hazelcast on Android gives random errors

<p>I'm trying to use Hazelcast on Android. I can include the dependency and the predefined "Hello World" will show up nicely without error. As soon as I put this code into my Activity (i.e. starting to use Hazelcast) it gives me an error:</p>
<p>Code:</p>
<pre><code>protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Config cfg = new Config();
HazelcastInstance instance = Hazelcast.newHazelcastInstance(cfg);
}

<p>It can't seem to find some classes which are always working and are part of the Android Library. When I try to find the code I can find it. When I remove the instance creation of Hazelcast there is no problem either..</p>
<p>Anybody has an idea what this problem might be?</p>
<p>Thanks in advance!</p>

Adding a module in WildFly 8.2.0 Final release
|
<p>I am new in JBoss and I try to add a jdbc driver for derby as a module in WidlFly 8.2.0.</p>
<p>What I did: </p>
<ul>
<li>I added the org/apache/derby/main folder in the JBOSS_HOME/modules/system/layers/base directory</li>
<li>In this new folder, I added derbyclient.jar (from jdk 1.8.0_40, it contains the driver) and a new <code>module.xml</code> file.</li>
</ul>
<p>The <code>module.xml</code> file is as follows: </p>
<pre><code> <?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.0" name="org.apache.derby">
<resources>
<resource-root path="derbyclient.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
</dependencies>
</module>
</code></pre>
<p>Then, I updated the <code>standalone.xml</code> file as follows:</p>
<ul>
<li>addition of this tag (in <code><extensions></code>): <code><extension module="org.apache.derby"/></code></li>
</ul>
<p>Declaration of my datasource and of the driver: </p>
<pre><code><datasource jndi-name="java:/DerbyDS" pool-name="DerbyDS" enabled="true" use-ccm="false">
<connection-url>jdbc:derby:MyDB;create=true</connection-url>
<driver>org.apache.derby</driver>
<security>
<user-name>demo</user-name>
<password>demo</password>
</security>
<validation>
<validate-on-match>false</validate-on-match>
<background-validation>false</background-validation>
</validation>
<statement>
<share-prepared-statements>false</share-prepared-statements>
</statement>
</datasource>
<drivers>
<driver name="org.apache.derby" module="org.apache.derby">
<xa-datasource-class>org.apache.derby.jdbc.ClientXADataSource</xa-datasource-class>
</driver>
<driver name="h2" module="com.h2database.h2">

Page accessible only if logged in
|
<p>Hello Stackoverflowers</p>
<p>Im new to PHP and im trying to make a members area for my testpage. I have made a successful register and login page, but now when I changed the code so if I log in correctly it redirects my to a page, and if I log in with wrong information it send me to a different page. However the members area is accessible if you type the location in the address-bar. Now, here's what I need help with, When someone tries to access that location without being logged in it should say "Access denied" but when you log in, it should redirect you to the members area and all it content is shown.</p>
<p>Here is my code:</p>
<p>login.php</p>

$username = $_POST['username'];
$password = $_POST['password'];

Refresh v-model
|
<p>I'm developing question paper application.
<img src="https://i.stack.imgur.com/wPpKx.png" alt="enter image description here"></p>
<p>Once I type a question and hit the "+" button, the question goes to the question paper array and counter increased by one.
The problem is after I hit the "+" button, then also the question which I have entered previously is still in the fields of the UI. <strong>Because of I use v-model to bind the data fields.</strong></p>
<p>What I want is a method to clear those previous question data in UI.
This is something similar to reset button function.</p>

How to fix in Unity "A failure occurred while executing com.android.build.gradle.internal.tasks.workers$actionfacade"
|
<p>I am working with adMob mediation in Unity. I have integrated inMobi and Unity ads network. After integrating them I am getting the following error "A failure occurred while executing com.android.build.gradle.internal.tasks.workers$actionfacade". Without integrating inMobi and Unity ads the build is successful. I just don't understand what is the problem</p>
<p>I looked up to a similar question in Unity forum <a href="https://forum.unity.com/threads/a-failure-occurred-while-executing-com-android-build-gradle-internal-tasks-workers-actionfacade.958112/" rel="nofollow noreferrer">https://forum.unity.com/threads/a-failure-occurred-while-executing-com-android-build-gradle-internal-tasks-workers-actionfacade.958112/</a> and tried solving by correctly entering the password,restarting Unity, creating seperate build file folder,etc but unfortunately nothing is working.</p>
<p>I saw similar question in stackOverflow, but they were for flutter,Cordova,etc and not Unity<a href="https://i.stack.imgur.com/HOrVX.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/HOrVX.png" alt="ScreenShot of the error" /></a></p>
<p>Some of the content of the Editor Log file near the error:</p>

How to convert an XML elements value to an int using linq- c#
|
<p>I'm trying to get the value out of my XML element and convert it to an integer using linq commands so I can do some mathematical equations using it.</p>
<p>This is how I've tried it so far:</p>
<pre><code>private void buttonTab4Mod1Calculate_Click(object sender, EventArgs e)
{
var document = XDocument.Load(workingDir + @"\Level4.xml");
var assessmentOneWeight = from d in document.Descendants("moduleTitle")
where d.Value == (String)comboBoxTab4Mod8.SelectedItem
select d.Parent.Element("assessmentOneWeight").Value;
int a = 0;
foreach (var item in assessmentOneWeight)
{
a = Convert.ToInt32(item);
}
MessageBox.Show(a.ToString());
}
</code></pre>
<p>but the value is still 0 for some reason.</p>
<p>This is my xml file:</p>

How to stop R from leaving zombie processes behind
|
<p>Here is a little reproducible example:</p>
<pre><code>library(doMC)
library(doParallel)
registerDoMC(4)
timing <- system.time( fitall <- foreach(i=1:1000, .combine = "c") %dopar% {
print(i)
})
</code></pre>
<p>I start up <code>R</code> and look at the process table:</p>
<pre><code>> system("ps -efl")
F S UID PID PPID C PRI NI ADDR SZ WCHAN STIME TTY TIME CMD
4 S chbr 1 0 5 80 0 - 21399 wait 10:58 ? 00:00:00 /usr/local/lib/R/bin/exec/R --no-save --no-restore
0 S chbr 9 1 0 80 0 - 1113 wait 10:58 ? 00:00:00 sh -c ps -efl
0 R chbr 10 9 0 80 0 - 4294 - 10:58 ? 00:00:00 ps -efl
</code></pre>
<p>If I use the aformentioned simple for loop <code>doMC</code> or <code>doParallel</code> leave a zombie process behind. Output of <code>ps -efl</code> after running the loop:</p>
<pre><code>> system("ps -efl")
F S UID PID PPID C PRI NI ADDR SZ WCHAN STIME TTY TIME CMD
4 S chbr 1 0 4 80 0 - 25256 wait 11:00 ? 00:00:00 /usr/local/lib/R/b
1 Z chbr 10 1 0 80 0 - 0 exit 11:00 ? 00:00:00 [R] <defunct>
0 S chbr 12 1 0 80 0 - 1113 wait 11:00 ? 00:00:00 sh -c ps -efl
0 R chbr 13 12 0 80 0 - 4294 - 11:00 ? 00:00:00 ps -efl
</code></pre>
<p>If I repeat the loop without issuing <code>registerDoMC(4)</code> again no additional zombie process gets created. However, if I issue <code>registerDoMC(4)</code> an additional zombie process gets created:</p>
<pre><code>> system("ps -efl")
F S UID PID PPID C PRI NI ADDR SZ WCHAN STIME TTY TIME CMD
4 S chbr 1 0 0 80 0 - 25554 wait 11:00 ? 00:00:01 /usr/local/lib/R/b
1 Z chbr 21 1 0 80 0 - 0 exit 11:02 ? 00:00:00 [R] <defunct>
1 Z chbr 22 1 0 80 0 - 0 exit 11:02 ? 00:00:00 [R] <defunct>
0 S chbr 26 1 0 80 0 - 1113 wait 11:03 ? 00:00:00 sh -c ps -efl
0 R chbr 27 26 0 80 0 - 4294 - 11:03 ? 00:00:00 ps -efl
</code></pre>
<p>That's how I figured it could be <code>doMC</code> which is doing something that should not be done. If doMC is causing this is there a way to stop <code>doMC</code> from leaving zombie processes behind? (<code>stopCluster()</code> does not work as no cluster gets created in the first place.)</p>

Storing user input into linked list - C
|
<p>I have an assignment for C beginner class: I'm supposed to create a structure that has one variable (named value) and one pointer to the list. I'm supposed to prompt the user for 5 values as input and store them in the linked list. Then print out the list. I can't figure out how to store input into the list. I did manage to write a program in which I initialize the 5 values. But I don't know how to accept input and store it into the list. </p>
<p>Here's the working program where I initialize the values:</p>
<pre><code>#include <stdio.h>
struct list
{
double value;
struct list *nextVal;
};
int main()
{
struct list v1 = {10};
struct list v2 = {17.97};
struct list v3 = {166};
struct list v4 = {2};
struct list v5 = {387.55};
struct list *first;
first = &v1;
v1.nextVal = &v2;
v2.nextVal = &v3;
v3.nextVal = &v4;
v4.nextVal = &v5;
v5.nextVal = NULL;
printf("All the values are: %.2f, %.2f, %.2f, %.2f, %.2f.",
first->value,v1.nextVal->value,v2.nextVal->value,
v3.nextVal->value,v4.nextVal->value);
return 0;
}
</code></pre>
<p>Here's a program where I tried getting user input and storing that into the list. (I only have 2 values instead of 5, cuz it's easier to work with that when trying to make it work.) When I compile this program, I get no errors. When I run it, I am properly prompted for the two input values; however, when the output that the program prints just writes 0 for both values. My assumption is that I'm storing the value into the list wrong - because I don't know how it's actually done. (Can't find any info in my textbook or online.) Last night someone commented on a different question I had to try using breakpoint to find out exactly where the problem is - I've been trying to figure it out since then but don't know how to do that yet. (I'm assuming it's something very simple - but everywhere I looked online, people explain it in a way that seems like I'm supposed to know what they're talking about - which I don't - And honestly, even if I could figure it out, I still wouldn't know what to do with that information, since I just can't find any information on how to store user input into a linked list.) Anyways, so here's my trial program that complies and runs but gives me 0 for both final values:</p>
<pre><code>#include <stdio.h>
struct list
{
double value;
struct list *nextVal;
};
int main()
{
double val1,val2;
printf("Please enter a number: ");
scanf("%f",&val1);
printf("Please enter a number: ");
scanf("%f",&val2);
struct list v1 = {val1};
struct list v2 = {val2};
struct list *first;
first = &v1;
v1.nextVal = &v2;
v2.nextVal = NULL;
printf("The two values entered are %.2f and %.2f.",
first->value,v1.nextVal->value);
return 0;
}
</code></pre>
<p>Thank you in advance! And I'm reaaaally a beginner - so even if you suggest something super easy - I might have no clue what it is..so please explain! Thank you!</p>

Jenkins Pipeline does not run with docker-compose because it cant connect to docker daemon
|
<p>I am trying to build an docker image and start the container with docker-compose inside a Jenkins pipeline. </p>
<p>I have a custom docker image for my Jenkins where I use the Jenkins out of the box image and install Docker CE and docker compose.</p>
<p>The Dockerfile:</p>
<pre><code>FROM jenkins/jenkins:2.159
USER root
# create dir to save jenkins log files
RUN mkdir /var/log/jenkins
RUN chown -R jenkins:jenkins /var/log/jenkins

</code></pre>
<p>I build this image with <code>docker-compose build</code> with this docker-compose file: </p>
<pre><code>version: '3'
volumes:
jenkins-log:
jenkins-data:
networks:
jenkins-net:
services:
master:
build: ./jenkins-master
ports:
- "50000:50000"
volumes:
- jenkins-log:/var/log/jenkins
- jenkins-data:/var/jenkins_home
- /var/run/docker.sock:/var/run/docker.sock
networks:
- jenkins-net
nginx:
build: ./jenkins-nginx
ports:
- "80:80"
networks:
- jenkins-net
</code></pre>
<p>And start it with <code>docker-compose -p jenkins up -d</code></p>
<p>This starts Jenkins and works fine for now. </p>
<p>Then I create a Pipeline Job which uses the following Jenkinsfile:</p>
<pre><code>node {
stage('Build Docker Image') {
sh '''
cd env-ci/
docker-compose --version
docker --version
docker-compose build
'''
}
}
</code></pre>
<p>When I run this pipeline I get the following error: </p>
<pre><code>+ cd env-ci/
+ docker-compose --version
docker-compose version 1.22.0, build f46880fe
+ docker --version
Docker version 18.09.1, build 4c52b90
+ docker-compose build
Couldn't connect to Docker daemon at http+docker://localhost - is it running?
If it's at a non-standard location, specify the URL with the DOCKER_HOST environment variable.
</code></pre>
<p>When I try to run <code>docker info</code> within the pipeline: </p>
<pre><code>node {
stage('Build Docker Image') {
sh '''
cd env-ci/
docker-compose --version
docker --version
docker info
'''
}
}
</code></pre>
<p>I get the following error: </p>
<pre><code>+ cd env-ci/
+ docker-compose --version
docker-compose version 1.22.0, build f46880fe
+ docker --version
Docker version 18.09.1, build 4c52b90
+ docker info
Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.39/info: dial unix /var/run/docker.sock: connect: permission denied
</code></pre>
<p>I am currently out of ideas what the issue might be or how I can resolve it.
The Jenkins pipeline is run as user <code>jenkins</code> and this user is added to the docker group. So the permission <em>should</em> be fine?!</p>
<p>Does anyone have an idea what might be wrong?
Thank you!</p>
