How does a Java if statement work when it has an assignment and an equality check OR - d together? <p>Why does this if statement, with an assignment and equality check, evaluate to false?</p>
<pre><code>public static void test() {
boolean test1 = true;
if (test1 = false || test1 == false) {
System.out.println("Yes");
} else {
System.out.println("No");
}
}
</code></pre>
<p>Why is this printing <code>No</code>?</p>
| <p>Because of <a href="https://docs.oracle.com/javase/tutorial/java/nutsandbolts/operators.html">operator precedence</a>. It is equivalent to this:</p>
<pre><code>boolean test1 = true;
if (test1 = (false || test1 == false)) {
...
}
</code></pre>
<p>The part in brackets evaluates to <code>false</code>.</p>

javascript only work in 1 data <p>I'm trying to get button hidden using javascript.
here the javascript code:</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-html lang-html prettyprint-override"><code><script>
var btn = document.getElementById("view1");
var a="<?php echo $data[0]->status==1;?>";
if(!a==0){
btn.style.display = 'none';
}
</script>
<script>
var btn = document.getElementById("view2");
var a="<?php echo $data[0]->status;?>";
if(!a==0){
btn.style.display = 'none';
}
</script></code></pre>

<p>but actually only 1 data javascript worked</p>
| <p>You can't have multiple elements with the same ID in one HTML document. IDs (identifiers) are supposed to be unique. Look into <code>name</code> or <code>class</code> and selecting multiple elements using <code>document.getElementsByName</code> or <code>document.getElementsByClassName</code>.<br>
Alternatively, if your HTML is generated from PHP as well, display / hide the buttons in the HTML directly.</p>

Setting up Boost 1.62 in CLion windows <p>I have been trying to set up boost 1.62 in CLion for past two days now. I have seen almost all the stack question but still couldn't do it.</p>

Javascript load multiple csv and create global reachable array <p>I need to load a lot of csv files. Yet Im loading with this function.</p>
<pre><code>$.ajax({
url: 'my.csv',
dataType: 'text',
}).done(successFunction);
</code></pre>
<p>Then I run successFunction, with that I create array and with same code as above, but with different name of function I create another array and so on. Thats o lot of same code. What is the simpliest way to load multiple csv and return array?</p>
<p><strong>Important</strong>
I need to sometimes create 2 dimensional array another time 5 etc. So function must include parameter for that. </p>
<p>For creating array im using function like this:</p>
<pre><code>function successFunction(data) {
var promenna = data.replace(/\n/g,";").split(";");
var result = [];
for (var i = 0; i < promenna.length; i+=2) {
var line = [];
line.push(promenna[i]);
line.push(promenna[i+1]);
result.push(line);
}
for (var i = 0; i < result.length; i += 1){
$("#tyden" + i + "").append(result[i][0]);
$("#tyden" + i + "kolik").append(result[i][1]);
}
}
</code></pre>
<p>But for another file I repeating basicly the same code. I don't know how to use one function for all files. </p>
| <p>First off, I disrecommend using your own CSV parser. This problem has been solved, use <a href="https://github.com/gkindel/CSV-JS" rel="nofollow">a library</a>.</p>
<p>The other part of the problem is <em>"I need to load many files via HTTP with jQuery"</em>, and that's easy.</p>
<ol>
<li>Prepare a list of file urls.</li>
<li>Turn that into a list of requests.
<ul>
<li>You can use jQuery's <code>.then()</code> to transform the incoming data on the fly.</li>
<li>In this case, passing it through the CSV parser would be the transformation.</li>
<li>You can use jQuery's <code>.done()</code> to handle responses individually, as they come in.</li>
</ul></li>
<li>Optional: Wait for the requests to complete.
<ul>
<li>You can use jQuery's <code>.when()</code> to wait on multiple async operations.</li>
<li>You can use jQuery's <code>.done()</code> to handle responses collectively.</li>
</ul></li>
</ol>
<p>So:</p>
<pre><code>var files = ['csv1.txt', 'csv2.txt', 'csv3.txt', 'csvN.txt'];
var requests = $.map(files, function (i, url) {
return $.get(url).then(CSV.parse);
});
$.when.apply($, requests)
.done(function (csvObjects) {
// everything has loaded successfully
$.each(csvObjects, function (i, csv) {
// do something with each file
});
})
.fail(function (jqXhr, status, error) {
// something went wrong, handle the error
});

How is handled auto fill form in Vaadin Framwork <p>I need to fix error in form. when user enters a birth number. It based on this information fills textfields for sex/ date birth. It is created in Vaadin. Did i miss something. How does it know what is entered and how does it parse ? Is it doing parsing? </p>
| <p>My bad, i should have to check method for pre - validation first. At the time i asked this, i didn´t know how it is being implemented. Simple parser was used but one check method prevented that from execution. Thanks though.</p>

use notifyDataSetChanged(); after updating SQLite from other activity and inside the same activity <p>Good day,<br>
Summary : I am making a sample memo app with SQLite as its database. </p>
<p><strong>MainActivity</strong> </p>
<pre><code>@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_list);
lv = (ListView)findViewById(R.id.memo_list_view);
Cursor c = SplashActivity.db.rawQuery("SELECT * FROM memos", null);
if(c.getCount()!=0) {
while(c.moveToNext()) {
memoDetails = new MemoDetails();
memoDetails.setmMemoId(c.getString(0));
memoDetails.setmMemoTitle(c.getString(1));
memoDetails.setmCreatedDate(c.getString(3));
memoDetails.setmAlarmedDate(c.getString(4));
memos.add(memoDetails);
}
c.close();
customAdapter = new CustomAdapter(this, memos);
lv.setAdapter(customAdapter);
}
@Override
protected void onResume() {
super.onResume();
customAdapter.notifyDataSetChanged();
}
</code></pre>
<p>Then this is the activity where I add my memo </p>
<p><strong>AddMemoActivity</strong> (this is the listener I use) </p>
<pre><code> saveMemo.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v1) {
if(memoTitle.getText().toString().trim().length() == 0 ||
memoContent.getText().toString().trim().length() == 0) {
showMessage("Error", "Please Enter All Values");
} else {
SimpleDateFormat sdf = new SimpleDateFormat("MMMM dd, yyyy HH:mm:ss");
String currentDateandTime = sdf.format(new Date());
SplashActivity.db.execSQL("INSERT INTO memos VALUES(null,'"
+ memoTitle.getText() + "','"
+ memoContent.getText() + "','"
+ currentDateandTime + "','"
+ currentDateandTime + "','0');");
showMessage("Success", "Memo is Saved.");
}
}
});
</code></pre>
<p>On this "Adding Memo" part, my problem is when I leave my <strong>AddMemoActivity</strong> and return to my <strong>MainActivty</strong>, it doesn't update my listview. </p>
<p>Second is my delete part, </p>
<p><strong>MainActivity</strong> </p>
<pre><code> findViewById(R.id.del_memo).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v1) {
DialogInterface.OnClickListener dialogClickListener = new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
switch (which){
case DialogInterface.BUTTON_POSITIVE:
String deleteIds = null;
for (MemoDetails p : customAdapter.getBox()) {
if (p.mCheckBox){
if(deleteIds == null) {
deleteIds = p.getmMemoId();
} else {
deleteIds += ", " + p.getmMemoId();
}
}
}
SplashActivity.db.execSQL("DELETE FROM memos WHERE id IN ('"+deleteIds+"')");
customAdapter.notifyDataSetChanged();
Toast.makeText(getApplicationContext(), deleteIds,
Toast.LENGTH_LONG).show();
break;
case DialogInterface.BUTTON_NEGATIVE:
//No button clicked
break;
}
}
};
AlertDialog.Builder builder = new AlertDialog.Builder(MemoListActivity.this);
builder.setMessage("Are you sure?").setPositiveButton("Yes", dialogClickListener)
.setNegativeButton("No", dialogClickListener).show();
}
});
</code></pre>
<p>As you can see, I already added <strong>customAdapter.notifyDataSetChanged();</strong> after deletion but still no update. </p>
<p>Thanks in advanced.</p>
| <p>Listview doesnt update by updating DB. You need to update the list you gave the adapter and then call notifyDataChange().</p>
<p>So update the list you gave the listview's udapter everytime you change the DB data.</p>
<p>Just update the <code>memos</code> list then call notify data change.</p>

<pre><code>// main.cpp
#include <iostream>
#include "Header.h"
int main() {
MyClass::TestFunction(); //'MyClass::TestFunction': illegal call of non-static member function
}
</code></pre>
<hr>
<pre><code>// header.h
#ifndef HEADER_H
#define HEADER_H
#include <iostream>
class MyClass {
public:
void TestFunction() {
std::cout << "Hello World\n"; //Where I beleive the issue is
}
};
#endif
</code></pre>
<hr>
<p>Now I <em>think</em> the issue comes from <code>std::cout</code> not being static and the declaration in <code>main.cpp</code> needs it to be static, but I'm not sure how to make it static so that <code>main.cpp</code> works correctly. If anyone could give me a tip as to how I can make things like this work later on down the road, that would be awesome :)</p>

</blockquote>
<p>You either have to make your function static OR to intanciate an object of your class and hen call its function :</p>
<p>main.cpp</p>
<pre><code>int main() {
MyClass pony;
pony.TestFunction();
}
</code></pre>
<p>OR</p>
<p>header.h</p>
<pre><code>class MyClass {
public:
static void TestFunction() {
std::cout << "Hello World\n"; //@Gill Bates
}
};

Sending push notifications's token to the server. Alamofire error <p>I'm trying to send token which I got in <code>didRegisterForRemoteNotificationsWithDeviceToken</code> to the server. But I got an error while sending: <code>Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Invalid type in JSON write (Foundation._SwiftNSData)</code>. For requests I use <code>Alamofire</code> framework. My code:</p>
<pre><code>func signUp(withToken token: Data, completion: (Error) -> Void) {
let parameters: Parameters = ["registration_id": token]
print("token = \(token)")
Alamofire.request(baseUrl + signUpPath, method: .post, parameters: parameters, encoding: JSONEncoding.default).responseJSON(completionHandler: {response in
})
}
</code></pre>
<p><code>Print</code> shows me: <code>token = 32 bytes</code>. Any suggestions? Maybe I need some additional steps with <code>Data</code> type before send it to the server?</p>
<p><strong>UPDATE</strong></p>
<p>I have tried to convert token to <code>NSString</code> type but got <code>nil</code></p>
<pre><code>let tokenNSString: NSString? = NSString(data: token, encoding: String.Encoding.utf8.rawValue)
print("nsstrgin from token = \(tokenNSString)")
</code></pre>
| <p>The <code>deviceToken</code> you are getting inside your project's appDelegate <code>didRegisterForRemoteNotificationsWithDeviceToken</code> is an <code>NSData</code> object. To extract the actual token String from that <code>NSData</code> object use this following code.</p>
<pre><code> let tokenChars = UnsafePointer<CChar>(deviceToken.bytes)
var tokenString: String = ""
for i in 0..<deviceToken.length {
tokenString += String(format: "%02.2hhx", arguments: [tokenChars[i]])
}
print("This is My Device Token for Push notification -", tokenString)
</code></pre>
<p>Now, <code>tokenString</code> is your actual token which you are looking for. Try to send this to your server along with any key.</p>
<p>BTW I am using Xcode 7.3.1 with Swift 2.2. Please feel free to modify this as per your requirements.</p>
<p>Thanks,
Hope this helped.</p>

ImportError: No module named 'bs4' in django only <p>The same question has been asked a number of times but I couldn't find the solution.</p>
<p>After I install a package using pip, I am able to import it in python console or python file and it works as expected.
The same package when I try to include in django, it gives <code>import error</code>.
Do I need to modify <code>settings.py</code> file or any requirement that I need to add? I am driving django with the help of virtual env. </p>
<p>Eg:
I am using <code>BeautifulSoup</code> and I am trying to import <code>from bs4 import BeautifulSoup</code> and I am getting error <code>ImportError: No module named 'bs4'</code></p>
<p>This error only comes in django. I am not able to figure out why this is happening.</p>
<p>Screenshot attached for reference.</p>
<p><strong>1. python console - shows no error</strong></p>
<p><a href="http://i.stack.imgur.com/exmvN.png" rel="nofollow"><img src="http://i.stack.imgur.com/exmvN.png" alt="python2 and python3 console"></a></p>
<p><strong>2. django console- import error</strong></p>
<p><a href="http://i.stack.imgur.com/j0IMN.png" rel="nofollow"><img src="http://i.stack.imgur.com/j0IMN.png" alt="django console"></a></p>
<p><em>I am sorry as it is difficult to read the console but any other thing that I can include which will help me make myself more clear will be appreciated.</em> </p>
| <p>You don't show either the code of your site or the command you ran (and the URL you entered, if any) to trigger this issue. There's almost certainly some difference between the Python environment on the command line and that operating in Django.</p>
<p>Are you using virtual environments? If so, dependencies should be separately added to each environment. Were you operating from a different working directory? Python usually has the current directory somewhere in <code>sys.path</code>, so if you changed directories it's possible you made <code>bs4</code> unavailable that way.</p>
<p>At the interactive Python prompt, try</p>
<pre><code>import bs4
bs4.__file__
</code></pre>
<p>That will tell you where <code>bs4</code> is being imported from, and might therefore give you a clue as to why it's not available to Django.</p>

Correct header for copying HTML on the clipboard <p>I have a complete HTML document and need to copy it on the clipboard so that it can be pasted into Microsoft Word and other applications. Now I figured out that the obvious way doesn't work and I need to add a special header before the HTML content. Unfortunately all samples seem to show invalid header data so that I can't learn from it. And all I can find is cryptic sample code that handles all sorts of complicated use cases, still that doesn't help me. And there isn't a readable explanation of the header numbers anywhere.</p>
<p>So here's a sample HTML document that I have as string in .NET:</p>
<pre><code><!doctype html>
<html>
<body>
<table>
<tr>
<td>Col 1</td>
<td>Col 2</td>
</tr>
</table>
</body>
</html>
</code></pre>
<p>If this fragment thing is really required, I might add those comments in my document just inside the <code><body></code> element.</p>
<p>The header is supposed to look somehow like this:</p>
<pre><code>Version:0.9
StartHTML:1
EndHTML:2
StartFragment:3
EndFragment:4
StartSelection:3
EndSelection:4
</code></pre>
<p>What are the correct numbers for 1, 2, 3, and 4? How are they calculated, considering UTF-8 encoding and all that's required? Please provide a plain text description or algorithm, or simple C# code for only this simple case, nothing fancy with bells and whistles. I can adapt from there.</p>
| <p>Okay, so I figured out that the fragment thing is not required. The header has the following numbers:</p>
<ul>
<li>1 and 3: The length of the header itself (zero-padding is necessary to achieve predictable results, otherwise the header length changes after putting in the numbers, making the numbers invalid)</li>
<li>2 and 4: The length of the header + the number of UTF-8 bytes of the entire HTML document</li>
</ul>
<p>This can be pasted into Word and Excel. No fragments or HTML comments required.</p>
<p>Sample C# code:</p>
<pre><code>int start = header.Length;
int end = header.Length + Encoding.UTF8.GetByteCount(html);
</code></pre>

Make sure sub directories don't listen to mod rewrite <p>I am using some dynamic pages on every .html file in my root.</p>
<p>With the following line:</p>
<pre><code>RewriteRule ^(.*).html content.php?alias=$1 [L]
</code></pre>
<p>This works fine, but I also got some other websites on the same location, only a few folders down. I don't want them to listen to this line, everytime I create a .html file, I get redirect to content.php in my root.</p>
<p>Example:</p>
<p>Location of my content.php:</p>
<pre><code>public_html/Website/content.php
public_html/Website/_intern/websites/index.html
</code></pre>
<p>The above file gets redirected to the content.php in my root.</p>
<p>How can I prevent that from happening?</p>
| <p>Tweak your regex. Instead of <code>.*</code> which matches anything you should use <code>[^/]+</code> to match anything but <code>/</code>. This ensures, you don't select anything in sub-directories:</p>
<pre><code>RewriteRule ^([^/]+)\.html$ content.php?alias=$1 [L,QSA,NC]
</code></pre>

Disable tax programmatically for a specific user role <p>In my woocommerce web site, I have enable Tax in general WooCommerce settings.</p>
<p>I would like to disable tax for a specific user role programmatically ( with any hooks ), from my shop, checkout page and from order email.</p>
<p>How could I achieve this?</p>
<p>Thanks</p>
| <blockquote>
<p>You can't disable WooCommerce tax for a specific user role programmatically, <strong>but you can apply for a specific user role a zero tax rate.</strong></p>
</blockquote>
<p>First you need to have this specific user role set in worpress. If it's the case, let say that this custom user role is <strong><code>'resellers'</code></strong> for my code example.</p>
<p>Second, you have to enable in WooCommerce settings a <strong>zero tax rate</strong>:</p>
<p><a href="http://i.stack.imgur.com/apAxb.png" rel="nofollow"><img src="http://i.stack.imgur.com/apAxb.png" alt="enter image description here"></a></p>
<p>And then for each country, you will have to set this <strong>zero tax rate</strong>:</p>
<p><a href="http://i.stack.imgur.com/6wF3e.png" rel="nofollow"><img src="http://i.stack.imgur.com/6wF3e.png" alt="enter image description here"></a></p>
<p>Third - Then this function hooked in <strong><code>woocommerce_product_tax_class</code></strong> will do the trick:</p>
<pre><code>function zero_rate_for_custom_user_role( $tax_class, $product ) {
// Getting the current user
$current_user = wp_get_current_user();
$current_user_data = get_userdata($current_user->ID);
// <== <== <== <== <== <== <== Here you put your user role slug
if ( in_array( 'resellers', $current_user_data->roles ) )
$tax_class = 'Zero Rate';
return $tax_class;
}
add_filter( 'woocommerce_product_tax_class', 'zero_rate_for_custom_user_role', 1, 2 );
</code></pre>
<blockquote>
<p>You will just need to put instead of 'resellers' your desired user role slug.</p>
</blockquote>
<p><em>This code goes in function.php file of your active child theme (or theme) or also in any plugin file.</em></p>
<p>This code is tested and fully functional.</p>

Laravel eloquent - filter by concatenation of multiple columns <p>I'm new to Laravel, and I got stuck trying to perform the following. I have a simple users table with the following columns: </p>
<ul>
<li><code>id</code></li>
<li><code>first_name</code></li>
<li><code>last_name</code></li>
</ul>
<p>I'm about to make a user list with an option of filtering. One of the filters is <code>full_name</code>, but I do not store <code>full_name</code> of the users, and I can't modify the table structure.</p>
<p>Over a few days I got to this:</p>
<pre><code>$query = \DB::table('users');
$query->select(\DB::raw('CONCAT_WS(" ", `last_name`, `first_name`)
as `full_name`, id'))->having('full_name', 'LIKE',$input['filter_name']);
$result = $query->get(['*']);
</code></pre>
<p>But it's not working. </p>
<p><strong>Spec</strong>: I'm using the latest laravel. </p>
| <p>I think you forgot the wildcards in the LIKE statement.</p>
<p>Instead of this</p>
<pre><code>$query->select(\DB::raw('CONCAT_WS(" ", `last_name`, `first_name`)
as `full_name`, id'))->having('full_name', 'LIKE',$input['filter_name']);
</code></pre>
<p>Try:</p>
<pre><code>$query->select(\DB::raw('CONCAT_WS(" ", `last_name`, `first_name`)
as `full_name`, id'))->having('full_name', 'LIKE', '%' . $input['filter_name'] . '%');

How to create toggleable sidenav layout in React.js? <p>I am porting my layout from jQuery to React.js. This is very common one that consists of:</p>
<ul>
<li>header with toggle button</li>
<li>sidenav with navigation links</li>
<li>content whose width adapts to sidenav state.</li>
</ul>
<p>As you can imagine to achieve that a lot of (css) stuff is going on. I am really confused about possible approaches.</p>
<p>Here is mine:</p>
<pre><code>class CoreLayout extends Component {
constructor(props) {
super(props)
this.state = {
sidenavCollapsed: false
}
}
onSidenavToggle() {
const { sidenavCollapsed } = this.state
document.body.classList.toggle('collapsed', !sidenavCollapsed)
this.setState({ sidenavCollapsed: !sidenavCollapsed })
}
render() {
const { sidenavCollapsed } = this.state
return (
<div>
<Header onSidenavToggle={::this.onSidenavToggle}></Header
<Sidenav>
<div className="content">content</div>
</div>
)
}
}
</code></pre>
<p>I do all the styling according to class attached to body element:</p>
<pre><code>.collapsed .header {}
.collapsed .sidenav {}
.collapsed .content {}
</code></pre>
<p>Basically it's toggling sidenav width and content margin betwen 220 and 60.</p>
<p><strong>So...</strong></p>
<p>Should I pass collapsed property to each of layout elements and add class <code>collapsed</code> separately? What I am trying to achieve is <a href="http://demo.naksoid.com/elephant/flaming-red/" rel="nofollow">similar to this</a>.</p>
<p>What is the correct way of doing <code>fade-out-in</code> sidenav items animation? Till now I was using jQuery utilities, but I am not sure if directly using <code>window.requestAnimationFrame()</code> is correct. I have tried <code>ReactCSSTransitionGroup</code> with no success.</p>
| <p>Just add a <code>class</code> to the navbar on button toggle and animate the transition using css.</p>

On redash how to create a chart that shows counts of types <p>I am trying to create something similar to the example here:</p>
<p><a href="http://demo.redash.io/embed/query/387/visualization/518?api_key=cc11cd75d4f3934b17de1f0621abd2f0c9cce713" rel="nofollow">http://demo.redash.io/embed/query/387/visualization/518?api_key=cc11cd75d4f3934b17de1f0621abd2f0c9cce713</a></p>
<p>But I can not figure it out. If someone can explain how to create this specific chart it would be great.</p>
<p>You can assume I am using a similar dataset and query with mongodb.</p>
<p>This is the demo link with the query:
<a href="http://demo.redash.io/queries/387/source#518" rel="nofollow">http://demo.redash.io/queries/387/source#518</a></p>
| <p>The steps are:</p>
<ol>
<li>You write the query, run it and get the results.</li>
<li>Click on "+ New Visualization" (next to the table header).</li>
<li>Define your chart/visualization.</li>
</ol>
<p>But it's really hard to understand what part you can't figure out - do you have problem getting the results? Defining the chart?</p>
<p>In the future, it's better to use the <a href="https://discuss.redash.io" rel="nofollow">Redash's forum</a> for such questions, as I stumbled at this question by chance.</p>

Explicitly set the storage path of an image clicked using Cordova API <p>I am extremely new to Cordova and am working on the Android platform. I need to store an image in a custom location.
The <code>navigator.camera.getPicture</code> method stores the clicked image in the cache, but I need to store that image in a custom folder in the root. How can I accomplish this? Any suggestions in this regard will be appreciated.</p>
| <p>Camera plugin store data in Android/Data/my.package.com/ directory.This directory is always accessible from your app even if you didn't grant read/write permission in manifest file of Android.It is always safe to do this while developing a API.
If you still you want to change and store file at custom location then create your own plugin to achieve this.</p>

VBA Code - Skip some parts if some others are excecuted <p>I have written this piece of code but have gutted out the additional filler in between. Depending on time points selected, it will hide the appropriate rows.</p>
<p>Container 1 will always be filled, however, if another container is not selected, I want it to hide all the remaining rows without processing the rest of the code. So if Container 1 and 2 are selected, it will run the code for these without running the rest of the code.</p>
<p>Rewriting this as loop would be incredibly complex as there are so many possible timepoints, it is more an issue of skipping the code that is not relevant. Almost like a goto line or something? I don't know!</p>
<p>Is there any other way to make this code run more efficiently than temporarily disabling the DisplayPageBreaks, ScreenUpdating and Enable Events? There is no calculation performed on the page, only row hides.</p>
<p>For Example, if Q26 is blank (No container 2) I want it to go to the end of the code without processing anything else but how I have written it, it still process the rest of the code.</p>

Retrieving data from file and storing in variable c# <p>I want to create a file in which I can write certain text and then store it in variables because I must change the text depending on the PC they are on.My question is what type of file should I write my text in? (.txt , .xml , .xls , .etc) I know you can do on any type you want but for what type of file is c# built to do such a task?</p>
<p><p> To be more clearer (because I know I have a problem expressing what I want ) I will give an example.</p>
<h3>Text file:</h3>
<pre><code>SN:123321123
PCName:blabla
Something.else:Text
</code></pre>
<p>And I would like to extract <code>123321123</code> and store it in a variable SN a.s.o. from my perspective I think I should store them in excel files to return them using <code>sheet.get_Range("first", last);</code> ,but I want to know if there is a simpler way?</p>
| <p>Use XML, there is lots of support and documentation on how to do this online. Another arguably 'cleaner' result would be JSON. This uses a simple key value pair relationship which is similar to the example you posted. But both are good.</p>
<p>XML Example:</p>
<pre><code><?xml version="1.0"?>
<catalog>
<book id="bk101">
<author>Gambardella, Matthew</author>
<title>XML Developer's Guide</title>
<genre>Computer</genre>
<price>44.95</price>
<publish_date>2000-10-01</publish_date>
<description>XML example</description>
</book>
</catalog>
</code></pre>
<p>JSON Example:</p>
<pre><code>{
"id": 1,
"name": "A green door",
"price": 12.50,
"tags": ["home", "green"]
}

Javascript - Create new Date using a UK format and moment.js <p>I have a date in UK format "DD/MM/YYYY HH:mm" and I want to create a new date with javascript. I'm trying the following using moment.js but it doesn't recognise the timepart and simply adds on the current time.</p>
<pre><code> var myDate = "11/10/2016 09:00"
// The toDate() is equivalent to the javascript new Date() function
var newDate = moment(myDate, "YYYY-MM-DD HH:mm").val()).toDate();
// output:
// 20161011T091406Z
// Tue Oct 11 2016 09:14:06 GMT+0100
</code></pre>
<p>As you can see its changed the time part to the time the script is run.</p>
| <p>Figured it out myself by doing the following:</p>
<pre><code>var myDate = "11/10/2016 09:00"
myDate = moment(myDate, "DD/MM/YYYY HH:mm").toISOString();
var newDate = moment(myDate).toDate();

Database Selection Via ComboBox <p>I have a <code>combobox</code> that I would like to use to select the database from a selection available to the user. I have found plenty of information on populating the fields with table values but nothing on making a selection on which <code>.dbo</code> they can use. I'm guessing the same principle can be used as below...
but I would presume that (<code>database =</code>) needs to be taken out and replaced some how.
any advice would be appreciated</p>
<pre><code>var connectionString = "server = (local); database = database; integrated security = true;"
string Sql = "select database...";
SqlConnection _con = new SqlConnection(connectionString);
_con.Open();
SqlCommand cmd = new SqlCommand(Sql, conn);
SqlDataReader reader = cmd.ExecuteReader();
while (reader.Read())
{
combobox1.Items.Add(reader[0]);
}

Constraints getting changed when adding a view over window or navigation controller? <p>I had an application in which I need to display a custom status bar over all the application. For which I wrote this code in to the <code>didFinishLaunchingWithOptions:</code> method</p>
<pre><code>self.window.windowLevel = UIWindowLevelStatusBar;
</code></pre>
<p>Then in the viewController I created a view with (0, 0, width, 20) frame view and added some elements to it.</p>
<p>I am trying to add that view above the window like this</p>
<pre><code>AppDelegate *appdelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
[self.statusview setTranslatesAutoresizingMaskIntoConstraints:YES];
[appdelegate.window addSubview:statusview];
</code></pre>
<p>But it is getting added at the top left without having no elements. But when I am setting the width and adding the elements again then it is showing.</p>
<p>Can anybody help me on this?</p>
| <p>i think your problem is the view's width, make sure the width is right.</p>
<p>if the width is right and the problem is still here, please update your code and screenshot.</p>

Private or Public Image Setting for Autoscale in SL <p>I am trying to set Operating System for autoscale.</p>
<p>In case of Operating System, I have set the code with API below.</p>
<pre><code> /**
* Operating System
*/
String operatingSystem = "WIN_2012-STD-R2_64";
virtualGuestMemberTemplate.setOperatingSystemReferenceCode(operatingSystem);
</code></pre>
<p>It works fine with Operating system, but what about private or public image ?</p>
<pre><code> /**
* Public Image
*/
String GlobalIdentifier = "1176d22b-176a-499a-8d94-f9aaf29155a3";
virtualGuestMemberTemplate.setGlobalIdentifier(GlobalIdentifier);
</code></pre>
<p>It returns an error, invalid guest template.
How can I set VirtualGuestMemberTemplate for public and private Image ?</p>
<p><a href="http://i.stack.imgur.com/uJpPm.png" rel="nofollow"><img src="http://i.stack.imgur.com/uJpPm.png" alt="Select Operating system"></a></p>
| <p>keep in mind that the configuration of the VM in autoscale group is almost the same like the configuiration when you create a new VM using the SoftLayer_Virtual_Guest::createObject so to set the image template you need to do it like this:</p>
<pre><code>{
"blockDeviceTemplateGroup": {
"globalIdentifier": "07beadaa-1e11-476e-a188-3f7795feb9fb"
}
}
</code></pre>

How to disable page element on certain articles in Joomla <p>I want to make a 100% clean bootstrap template for Joomla 1.5 (i know i know but it runs as intranet application so it's safe - i dont want to mess with this ;) ) and wonder how to disable template element (ex. div) on certain article pages (not associated to selected category/section ID) or parent menu position. I want to hardcode it directly in template.</p>
<p><strong>I need something like this (example!)</strong></p>
<pre><code>{if JArticle->Category-ID != 2 && 3}Do something{else}Do something else{/if}
</code></pre>
| <p>First you need to get the article id from the request. I'm not sure if in Joomla 1.5 this is the correct way (on latest Joomla releases, JRequest is deprecated), but anyway, you'll need to use the JRequest class.</p>
<p><code>$id = JRequest::getInt('id');</code></p>
<p>Then use this id:</p>
<pre><code>if (($id != 2) && ($id != 3))
{
// id is not 2 nor 3
}
else
{
// otherwise
}
</code></pre>

PostgreSQL timeseries query with outer join <p>In PostgreSQL 9.5 database there is a table <em>metrics_raw</em> containing various metrics (<em>types: varchar</em>).<br>
Types are (for example): <em>TRA</em>, <em>RTC</em>.<br>
I'm executing following SQL to get year-to-date monthly aggregations:</p>
<pre><code>SELECT
count(*),
"ticks"."ts" AS "timestamp"
FROM
"metrics_raw"
RIGHT OUTER JOIN
generate_series('2016-01-01'::timestamp, '2016-10-10'::timestamp, '1 month'::interval) AS ticks(ts)
ON
"ticks"."ts" = date_trunc('months', "metrics_raw"."timestamp")
WHERE
"metrics_raw"."type" = 'TRA' OR
"metrics_raw"."type" IS NULL
GROUP BY "ticks"."ts"
ORDER BY "ticks"."ts"
</code></pre>
<p>The table contains some records of <em>TRA</em> type (~10 records) and 1 record of <em>RTC</em> type.<br>
Executing the query for <em>TRA</em> I get <strong>10</strong> rows result as expected, but for <em>RTC</em> query I get only <strong>7</strong> rows. One more thing is that having no <em>RTC</em> metrics I get <strong>10</strong> rows too. </p>
<p>Where could be a mistake?</p>
| <p>Thank @Nemeros, I fixed query to be:</p>
<pre><code>SELECT
"ticks"."ts" AS "timestamp"
FROM
generate_series('2016-01-01'::timestamp, '2016-10-10'::timestamp, '1 month'::interval) AS ticks(ts)
LEFT OUTER JOIN
(
SELECT *
FROM "metrics_raw"
WHERE "metrics_raw"."type" = 'TRA'
) as "metrics"
ON
"ticks"."ts" = date_trunc('months', "metrics"."timestamp")
GROUP BY "ticks"."ts"
ORDER BY "ticks"."ts"

How to call a wizard from other wizard in Odoo8? <p>I have a wizard in which there is a one2many field. I made a button in each line of the one2many which calls another wizard made by me. This wizard is for modifying some values of the selected line.</p>
<p>My purpose is to return the first wizard, with the new changes, when you click on the <strong>Apply</strong> button of my wizard.</p>
<blockquote>
<p>Example:</p>
<p>The first wizard has a one2many field with three records:</p>
<ul>
<li>Product A | 1 ud | Source location X | Dest location Y | Lot A1</li>
<li>Product B | 2 ud | Source location X | Dest location Y | Lot B1</li>
<li>Product C | 3 ud | Source location X | Dest location Y | Lot C1</li>
</ul>
<p>Now, I click on the first line button I made (each line has one), and
my wizard is opened. Here I can modify the lot of the first line (the
one with the Product A). Imagine I set Lot A0 and click on <strong>Apply</strong>.</p>
<p>I should return to the parent wizard, and see the same data except for
the changes made. So the result will be:</p>
<ul>
<li>Product A | 1 ud | Source location X | Dest location Y | <strong>Lot A0</strong></li>
<li>Product B | 2 ud | Source location X | Dest location Y | Lot B1</li>
<li>Product C | 3 ud | Source location X | Dest location Y | Lot C1</li>
</ul>
</blockquote>
<p>Does anyone know how to achieve this? How could I preserve the first wizard data?</p>
| <p>First you need to browse current record of Wizard and it's line. Afterward write value as you want. </p>
<p>Return that current id with wizard object.</p>
<p>Try with following trick:</p>
<pre><code>#apply button method logic
def apply_data(self, cr, uid, ids, context=None):
if not context:
context = {}
ctx = context.copy()
for wizard in self.browse(cr, uid, ids[0], context=context):
for line in wizard.one2many_field:
line.write({
'field_name': field_value
})
dummy, view_id = self.pool.get('ir.model.data').get_object_reference(cr, uid, 'module_name', 'wizard_form_view_name')
return {
'name':_("Name of your Wizard"),
'view_mode': 'form',
'view_id': view_id,
'view_type': 'form',
'res_id': ids and ids[0] or False,
'res_model': 'wizard.object.name',
'type': 'ir.actions.act_window',
'nodestroy': True,
'target': 'new',
'context': ctx
}
</code></pre>
<p>NOTE:</p>
<p>You can also update context value as well.</p>

Why do I get different errors when I use a non-existing alias in realurl? 404 with postvarsets, 500 with fixedpostvars <p>I have two different configurations for two different extensions.
With news I use postvarsets:</p>
<pre><code>'postVarSets' =>
array (
'_DEFAULT' =>
array (
'news' =>
array (
0 =>
array (
'GETvar' => 'tx_news_pi1[news]',
'lookUpTable' =>
array (
'table' => 'tx_news_domain_model_news',
'id_field' => 'uid',
'alias_field' => 'title',
'useUniqueCache' => 1,
'useUniqueCache_conf' =>
array (
'strtolower' => 1,
'spaceCharacter' => '-',
),
),
),
),
),
)
</code></pre>
<p>For an own extension to display categories I use fixedpostvars:</p>
<pre><code>'fixedPostVars' =>
array (
'category' =>
array (
0 =>
array (
'GETvar' => 'tx_myextension_plugin[mainCategory]',
'lookUpTable' =>
array (
'table' => 'sys_category',
'id_field' => 'uid',
'alias_field' => 'title',
'languageGetVar' => 'L',
'languageField' => 'sys_language_uid',
'transOrigPointerField' => 'l10n_parent',
'useUniqueCache' => 1,
'useUniqueCache_conf' =>
array (
'strtolower' => 1,
'spaceCharacter' => '-',
),
),

<p>If I now use some invalid URL in news, I get a 404 (which is completely right).
If I now use some invalid category in my URL, I get a 500 error with the error message:</p>
<blockquote>
<p>Exception while property mapping at property path "": The identity property "ergeriguehrgoiekweukw" is no UID.</p>
</blockquote>
<p>Why is there a difference between the two configurations and how can I get a 404 as well for the fixedpostvars?</p>
| <p>i am not sure but i think this is useful for you. add 'enable404forInvalidAlias' => 1, for getting 404 error. in fixedPostVars realURL configuration.</p>

One mail, multiple content depending the mail address <p>I don't know if it is possible or if it has already been asked.
But here's my problem.
I would like to send a mail to multiple address, and display in the mail, the mail address and some account information according the email address (not only the name).</p>
<p>Ex:
I send an email to <strong>john@gmail.com</strong>, <strong>jack@gmail.com</strong> & <strong>luke@gmail.com</strong>.</p>
<p>John will see "Hello <strong>John</strong>, ...",
Jack will see "Hello <strong>Jack</strong>, ...",
...</p>
<p>Is it possible to do it by sending a single mail? Or do I need to send 1 mail by account?</p>
<p>PS: I don't know if it can help, but I user PHPMailer.</p>
| <p>You will have to send separate emails to send different content.</p>
<p>If you want to make your life easier, though, you ought to use a template with PHPMailer and provide the necessary data. There are plenty of <a href="http://stackoverflow.com/questions/38158181/send-html-emails-using-phpmailer-and-html-templates">other questions</a> and <a href="https://github.com/PHPMailer/PHPMailer/wiki" rel="nofollow">documentation</a> on doing this.</p>
<p>Also note that if you are sending multiple emails you should be using BCC anyway or everyone will see everyone else's email address and you will most likely get hurt for spam.</p>

UserName - Password check function returning "false" <p>I'm having some trouble managing my login for a website. I've tried several different methods and queries which all seem to lead to the same problem: the method I use to check <code>username</code> and <code>password</code> always returns <code>false</code>.</p>
<p>To make it easier to understand, here's what I'm trying to do:</p>
<ul>
<li>Controller file calls view page and prompts user for <code>username</code> and <code>password</code></li>
<li>I'm using a <code>callback</code> function to set a rule for the form</li>
<li>the <code>callback</code> function calls Model method</li>
<li>Model method returns <code>TRUE</code> if login details are correct and <code>FALSE</code> otherwise.</li>
</ul>
<p>Apparently it always returns <code>FALSE</code> as the login never works ... </p>
<p>I'm using CodeIgniter.</p>
<p>Controller file:</p>
<pre><code>class Login extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->helper(array('form', 'url'));
$this->load->library(array('form_validation', 'session'));
}
public function index()
{
$this->form_validation->set_rules('username', 'Username', 'callback_login_check[password]');
if ($this->form_validation->run() == FALSE) {
//loading view as long as it is not correct
$this->load->view('login');

indexeddb objectstore.add() keypath = 'id' <p>i have a few object stores, and split things up between them. and during initial install of chrome extension, i am adding data to the various object stores, and i am wanting to make sure the data aligns up correctly. so when things go out of sync during install. the "keypath / id" will match things up correctly. nothing big there.</p>
<p>issue comes in after the initial install. and adding another record.
and the "id" / keyPath / key for initial records are showing id:1, id:2, id:3, etc...</p>
<p>but for a record after initial install. i no longer know what the key will be until it is added to the objectstore. is there a code snip i am missing so i can create an object and add to objecstore, to also up the id, or did i mess up originally creating id: 1 and should of used something like keyPath: 1 or key: 1 or Primarykey: 1?</p>
<p>i can take long way around it, and use some promises, and </p>
<pre><code>objectstore.add(object)
.then(objecstore.get(event.key)
.then(objestore.put(key, {"id":key})
</code></pre>
<p>i do note remember correct promise code to above. but objectstore.add, then getting key once added, then .put({"id": key}) to update "id" is done, is the jist of it. i am trying to prevent ever needing to do this in the first place.</p>
<p>kinda like in SQL like database, and having 2 primarykeys that are numbers, autoinncrement, and are exactly same in every way for the same table. but in my case, keys update, and "id" is taking up space. and not sure how to remove 'id' from initial get go. Or once done, how to keep keys and 'id' synced without a bunch of extra blah promises. </p>

| <p>You're using two features together - in-line keys and key generators. I'll explain them both separately then how they compose.</p>
<p><strong>In-Line and Out-of-Line Keys</strong></p>
<p><em>In-line keys</em> have the key value appear in the record itself - a store with a keyPath uses in-line keys. By contrast, <em>out-of-line keys</em> have the key value separate.</p>
<pre><code>var storeWithOutOfLineKeys = db.createObjectStore('s1');
storeWithOutOfLineKeys.put({name: 'alice'}, 1);
var storeWithInLineKeys = db.createObjectStore('s2', {keyPath: 'id'});
storeWithInLineKeys.put({name: 'bob', id: 1});
</code></pre>
<p>Calls to <code>put()</code> and <code>add()</code> will fail if you don't supply an explicit key for a store with out-of-line keys. Calls to <code>put()</code> and <code>add()</code> will fail if you <em>do</em> supply an explicit key to a store with in-line keys, and will fail if the record does not contain the in-line key value (e.g. missing the <code>id</code> property in the above example)</p>
<p><strong>Key Generators</strong></p>
<p>When you specify <code>autoIncrement: true</code> you're using what the spec calls a <em>key generator</em>. For each record added, if not specified otherwise then the first will get <code>1</code>, the second <code>2</code>, etc. You can find out what key was used by looking at the result of the <code>put()</code> or <code>add()</code> request, e.g.</p>
<pre><code>var request = store.put({name: 'alice'});
request.onsuccess = function() {
console.log('put got generated key: ' + request.result;
};
</code></pre>
<p><strong>Both In-Line Keys and Key Generators</strong></p>
<p>When a key generator is used, the behavior of <code>add()</code> and <code>put()</code> change:</p>
<p><em>Key generator and out-of-line keys:</em> it is not necessary to pass an explicit key when calling <code>add()</code> or <code>put()</code>; if omitted, the generated key is used:</p>
<pre><code>var storeWithOutOfLineKeys = db.createObjectStore('s1', {autoIncrement: true});
storeWithOutOfLineKeys.put({name: 'alice'});
</code></pre>
<p>If an explicit key is passed it <em>will</em> be used, either overwriting a previous record or adding a new one. (If the key passed happens to be a number higher than the generator value, the generator will be set to that number.)</p>
<p><em>Key generator and in-line keys:</em> it is not necessary to specify the key in the record when calling <code>add()</code> or <code>put()</code>; if omitted, the generated key is injected into the value.</p>
<pre><code>var storeWithInLineKeys = db.createObjectStore('s2', {keyPath: 'id'});
storeWithInLineKeys.put({name: 'bob'}).onsuccess = function(e) {
var id = e.target.result;
storeWithInLineKeys.get(id).onsuccess = function(e) {
console.log(JSON.stringify(e.target.result));
// {"name": "bob", "id": 1}
});
});
</code></pre>
<p>Similarly though, if the record <em>does</em> contain a key value it will be used instead. (And if it's a number higher than the key generator state, the key generator will be adjusted.)</p>
<p>I believe this last case matches what your code is doing - both in-line keys and a key generator. You can use the result of <code>add()</code> and <code>put()</code> requests to determine the key that was added, and update records by specifying the key explicitly in the record:</p>
<pre><code>storeWithInLineKeys.put({name: 'eve', id: 1}); // overwrites old #1
</code></pre>

Display route title inside root component <p>I have a root component and want to display route title inside special section in it.<br>I can detect which route is active in every component.<br>However, I don`t know how to do it inside root component. </p>
<p>This code shows title fine in ChildComponent1 :</p>
<pre><code>route:ActivatedRoute
ngOnInit() {
this.route.data.subscribe(
data => console.log(data)
)
}
</code></pre>
<p>How can I detect what is current route`s title and display it inside the root component?</p>
<pre><code>export const routes: Routes = [
{path: '', component: Component1, canActivate: [NonAuthGuard]},
{
path: 'root', component: rootcomponent, canActivate: [AuthGuard], children: [
{
path: 'Child1',
component: ChildComponent1,
data: {
title: 'Child1'
},
canActivate: [AuthGuard],
canDeactivate: [CanDeactivateGuard]
},
{
path: 'Child2',
component: ChildComponent2,
data: {
title: 'Child2'
},
canActivate: [AuthGuard],
canDeactivate: [CanDeactivateGuard]
},
]}
</code></pre>
| <p>You could inject <code>Router</code> in your root component and then subscribe its <strong>events</strong>.
Example:</p>
<pre><code>constructor(private router : Router) {
this.router.events.subscribe((event) => {
if(event instanceof NavigationStart) {
console.log(event);
console.log(event.url);
}
});
}
</code></pre>
<p>You should check if your event is instance of <code>NavigationStart</code> or <code>NavigationEnd</code>, because your event will fire <em>several</em> times.</p>

Using the same thread for other database operations after it has finished processing <p>I am writing an hibernate application which involves batch processing on the records stored.</p>
<p>Assume there are 30000 records stored in database table and i am using 30 threads. Each thread processes 1000 records in parallel i.e. batch by batch. Thread1 processes 1 to 1000 Thread2: 1001 to 2001, etc. Here process means i am performing a select operation on all of them in a batch. I am processing these records to send them to a web-service by parsing them.</p>
<p>The scenario is there is a column named status in the database table where if the record is accepted by the webservice then the status column of the record is made as 1 else 0.</p>
<p>Now the issue arises here when Thread1 finishes processing records with id's 1 to 1000 and Thread 2 is still processing 1001 to 2001. Assume the records with id's 5 to 30 and 40 to 50 status are 0 i.e. undelivered to the webservice. Now my scenario demands the thread which has finished processing i.e. Thread1 should start processing the records with id's 5 to 30 and 40 to 50 and try to redeliver the message in the record to the webservice.</p>
<p>I am using <code>ExecutorService</code> for coding the same, how to achieve the above.</p>
| <p>You could use a shared blocking queue, which is filled with the records you need to process (which means that you select those 30000 records somewhere outside of your <code>ExecutorService</code> threads).</p>
<p>Then, in your <code>Thread</code> code each thread gets top 1000 (<a href="https://docs.oracle.com/javase/8/docs/api/java/util/concurrent/ArrayBlockingQueue.html#drainTo-java.util.Collection-int-" rel="nofollow">using this method</a>) records from the queue and does it's processing. Here is the important part: the records rejected by a web-service are put back to the queue - so when another executor thread is available it will pick the undelivered.</p>
<p>You would need to add delivery counter to your records and check if a message is redelivered limited number of times (so they aren't redelivered forever if they are somehow malformed).</p>

Chef git sync using knife role create and new workstation setup <p>I have a simple question about keeping my chef-repo in sync with what's on the server.</p>
<p>Here is the steps I took to create a new role:</p>
<pre><code>cd /chef-repo/roles
knife role create windows_base
</code></pre>
<p>Then when I do:</p>
<pre><code>knife role list
</code></pre>
<p>I can see the new windows_base role appearing, however I do not see a json file created under roles. When I push this to git this file wont exist?</p>
<p>So when I go onto a different workstation and pull everything to that workstation, the role windows_base wont exist. Why is there no json file created when I do knife role create windows_base and there obviously is when creating a role manually using a .rb file.</p>
<p>Simply put - how can I keep my chef-repo in sync with git if there is no file created and the role is directly created on the server?</p>
| <p>The <code>knife * create</code> commands are issuing the create directly against the API. We don't offer generator commands (which live under <code>chef generate</code>) for roles, you'll just have to create the file yourself. In general you probably don't want to use the <code>create</code> commands, instead make the files you want and then <code>knife upload roles/</code>.</p>

Select Case to handle active TabPage <p>A program with a Form and a TabControl. I need to handle what happens when the user close the form according to the active TabControlPage</p>
<p>Is working with If - Then like this</p>

'What I want
End If
If PanelChooserTabControl.SelectedTab Is EditionTabPage Then
'The user can´t leave
e.Cancel = True
End If

<pre><code>Dim TabPageActive As String = PanelChooserTabControl.SelectedTab.ToString
Select Case TabPageActive
Case "TabPage:{SelectionTabPage}"
'What I want
Case "EditionTabPage"
'What I want
End Select
</code></pre>
<p>But the TabPageActive variable is loaded with something like
TabPage:{SelectionTabPage}</p>
<p>and not only "SelectionTabPage". Even using TabPage:{SelectionTabPage} as the Case variable (like the example code) is not working. </p>
<p><strong>Do I need to make another string conversion or trim?</strong></p>
| <p>You can try something like:</p>
<pre><code>Select Case True
Case PanelChooserTabControl.SelectedTab Is SelectionTabPage
Case PanelChooserTabControl.SelectedTab Is EditionTabPage
...
End Select
</code></pre>
<p>or on tabPage index change save as an enum the page and use this enum in the case.</p>

<p>Lets say we have a page in PCL xamarin forms application
I want to save the settings ( toggle switch choices ) for each users :
- save them locally and remotly</p>
| <p>Probably the fastest way to implement this is by using James Montemagno's <a href="https://github.com/jamesmontemagno/SettingsPlugin" rel="nofollow">Settings Plugin</a>. It's available as a NuGet package, just remember to install it in all of your projects both shared and platform.</p>
<p>It should be pretty self-explanatory. When you install the package it already creates a helper class for you and shows you a readme file.</p>
<p>It works only with simple types, being: <code>Boolean</code>, <code>Int32</code>, <code>Int64</code>, <code>String</code>, <code>Single</code>(float), <code>Guid</code>, <code>Double</code>, <code>Decimal</code>, <code>DateTime</code>.</p>
<p>When you installed the package you get a default static class to access your settings which looks like this:</p>
<pre><code>private static ISettings AppSettings
{
get
{
return CrossSettings.Current;
}
}
</code></pre>
<p>You can now define your settings with key/value pairs and define a default value, i.e.:</p>
<pre><code>private const string UserNameKey = "username_key";
private static readonly string UserNameDefault = string.Empty;
private const string SomeIntKey = "int_key";
private static readonly int SomeIntDefault = 6251986;
</code></pre>
<p>And retrieve them by properties, like this:</p>
<pre><code>public static string UserName
{
get { return AppSettings.GetValueOrDefault<string>(UserNameKey, UserNameDefault); }
set { AppSettings.AddOrUpdateValue<string>(UserNameKey, value); }
}
public static int SomeInt
{
get { return AppSettings.GetValueOrDefault<int>(SomeIntKey, SomeIntDefault); }
set { AppSettings.AddOrUpdateValue<int>(SomeIntKey, value); }
}
</code></pre>
<p>You can also use databinding in Xamarin.Forms so you don't need any redundant code. More in-depth can be read about in the documentation <a href="https://github.com/jamesmontemagno/SettingsPlugin#databinding-in-xamarinforms" rel="nofollow">here</a>.</p>
<p>Because it is using properties etc. you could implement some code yourself to call a backend service and store the settings there as well.</p>

</code></pre>
<p>so folks, how should I do this in IntelliJ ??</p>
| <p>You need to create the Run Configuration. Run -> Edit Configurations and add new configuration. Choose Spring boot and specify the main class and it should do it.</p>

Why componentDidMount gets called multiple times in react.js & redux? <p>I read <code>componentDidMount</code> gets called only once for initial rendering but I'm seeing it's getting rendered multiple times.</p>
<p>It seems I created a recursive loop.</p>
<ul>
<li>componentDidMount dispatches action to fetch data</li>
<li>upon receiving the data, it fires success action to store the data in redux state.</li>
<li>a parent react component is connected to redux store and has <code>mapStateToProps</code> for the entry that just changed in the above step</li>
<li>parent renders child components (which is programmatically selected via variable)</li>
<li>the child component's componentDidMount gets called again</li>
<li>it dispaches action to fetch data</li>
</ul>
<p>I think that's what's happening. I may be wrong. </p>
<p>How can I stop the loop?</p>
<p>Here's the code for programmatically rendering child components.</p>
<pre><code> function renderSubviews({viewConfigs, viewConfig, getSubviewData}) {
return viewConfig.subviewConfigs.map((subviewConfig, index) => {
let Subview = viewConfigRegistry[subviewConfig.constructor.configName]
let subviewData = getSubviewData(subviewConfig)
const key = shortid.generate()
const subviewLayout = Object.assign({}, subviewConfig.layout, {key: key})
return (
<div
key={key}
data-grid={subviewLayout}
>
<Subview
{...subviewData}
/>
</div>
)
})
}
</code></pre>
| <p>A component instance will only get mounted once and unmounted when it gets deleted. In your case it gets deleted and recreated.</p>
<p>The point of the <code>key</code> prop is to help React find the previous version of the same component. That way it can update a previous component with new props rather than create a new one. </p>
<p>React can often work fine without a key, the exception being a list with items. It wants a key there so it can keep track when items get rearranged, created or deleted.</p>
<p>In your case, you are explicitly telling React that your component is different from the previous one. You're giving a new key on each render. This forces React to treat the previous instance as having been deleted. Any children of that component are also unmounted and dismantled.</p>
<p>What you ought to do is not (ever) generate a key at random. Keys should always be based on the identity of the data a component is displaying. If it's not a list item you probably don't need a key. If it is a list item, it's much better to use a key derived from the data's identity, such as an ID property, or maybe a combination of multiple fields.</p>
<p>If generating a random key would have been the correct thing to do, React would have just taken care of that for you.</p>
<p>You should place your initial fetch code in the root of your React tree, usually that's <code>App</code>. Don't put it in some random child. At least you should put it in a component that exist for the lifetime of your app.</p>
<p>The main reason to put it in <code>componentDidMount</code> is so it doesn't run on the server, because server-side components never get mounted. This is important for universal rendering. Even if you're not doing this now, you might do this later, and being prepared for it is a best practice. </p>

What is the Regression algo to Use for this case? <p>Having this Data :</p>
<pre><code>clientId zipCode codeHeatingType countingType consumptionProfile householdCount squareFootage
01 75015 ELEC P012 A400 6 25

<p>and the AvgConsumtion</p>
<pre><code>clientId AvgConsumption

02 400 (KWH)
</code></pre>
<p>What machine learning to use to estimate the Avgconsumption depending on the client characteristics ? LogisticRegression ?, multilabel classification ?...</p>
<p>is it possible to have an exemple with string colums ?</p>
| <p>You need a regression algorithm that predicts a continuous variable. You can find the list of regression algorithms implemented in <code>spark.ml</code> <a href="http://spark.apache.org/docs/latest/ml-classification-regression.html#regression" rel="nofollow">here</a> with exemples.</p>
<p>Categorical predictors can be transformed in various ways using non-parametric (non-optimized) <code>Transformer</code> (see <a href="http://spark.apache.org/docs/latest/ml-features.html" rel="nofollow">http://spark.apache.org/docs/latest/ml-features.html</a>). For instance <a href="http://spark.apache.org/docs/latest/api/scala/index.html#org.apache.spark.ml.feature.OneHotEncoder" rel="nofollow">OneHotEncoder</a> will convert a categorical predictors in a set of binary predictors. Exemples are provided in the <a href="http://spark.apache.org/docs/latest/ml-features.html#onehotencoder" rel="nofollow">documentation</a>.</p>
<p>Note: inform you on some basics in machine learning before trying too much. There is a series of pitfalls that are purely of statistical nature. For specific questions, ask <a href="http://stats.stackexchange.com/">here</a></p>

Windows IOT printer support <p>I want to make usb printer work with Windows IOT (Raspberry PI), so I need a universal print driver compiled for ARM architecture. But I haven't found any out of box solutions for this. Tried to write it, but can't find a good tutorial.</p>
<p>Is there any out of box solutions? If no, maybe there is any open-source implementation that can be compiled for ARM processor? Or maybe good tutorial how to implement it?</p>
<p>P.S. Please don't recommend changing Windows IOT to Raspbian with Gutenprint. It's not sutable for my case.</p>
| <h1>Suggestions:</h1>
<h2>GDI</h2>
<ol>
<li>Turn on your raspberry pi, and browse to the c:\windows\system32 folder as shown in the picture below<br>
<a href="https://i.stack.imgur.com/bWeUu.png" rel="nofollow"><img src="https://i.stack.imgur.com/bWeUu.png" alt="enter image description here"></a></li>
<li>Copy the gdi32.dll and gdi32min.dll files from the raspberry pi "Windows Iot" image to your local pc. In this example I have copied them to my downloads folder.</li>
<li><p>Open visual studio command prompt for ARM and follow the steps in the screenshot below:
<a href="https://i.stack.imgur.com/UeqxV.png" rel="nofollow"><img src="https://i.stack.imgur.com/UeqxV.png" alt="enter image description here"></a></p></li>
<li><p>Examine the output in those 2 text files and ascertain which gdi functions are available.</p></li>
<li>You would then need to test each function that you might need to use and make sure it doesn't return "not implemented" or something similar.</li>
<li>Here is a link to a tutorial for printing from the GDI <a href="http://www.codeproject.com/Articles/764057/GDI-Drawing-and-Printing" rel="nofollow">http://www.codeproject.com/Articles/764057/GDI-Drawing-and-Printing</a></li>
</ol>
<p>So it looks like only old-school GDI functions are available, however this would be most similar to "universal" print driver output.</p>
<h2>Or Postscript / HP PCL</h2>
<p>Write your own postscript output. On Linux this can be accomplished by dumping postscript codes directly to the printer over the network via cups, or usb via cups. This is by far the easiest solution.</p>
<h2>Or line mode</h2>
<p>Use a line-mode printer over rs232 (receipt printer, zebra, intermec, it is 1970's technology, but still works - no graphics though)</p>

Hibernate CRUD with lists <p>If I have entitys:</p>
<ol>
<li>Entity1 has list with Entity2;</li>
<li>Entity2 has list with Entity3;</li>
<li>Entity3 has list with Entity4;</li>
</ol>
<p>What is operations in my code I have to do when I add new Entity4 in DB?</p>
<ol>
<li>Just set parent for Entity4 and save Entity4?</li>
</ol>
<p>or</p>
<ol start="2">
<li>Set parent for Entity4 and save Entity4. Add Entity4 in list of
Entity3 and save Entity3.</li>
</ol>
<p>or</p>
<ol start="3">
<li>Add Entity4 in list of Entity3 and save Entity3. And All Entitys will be update.</li>
</ol>
| <p>It really depends on whether the list maintained by <code>Entity3</code> is set to cascade operations such as <code>PERSIST</code>, <code>MERGE</code>, and <code>DELETE</code>. </p>
<p>If the list is configured to cascade, then all you'd need to do is:</p>
<ul>
<li>Set the parent of <code>Entity4</code>.</li>
<li>Add <code>Entity4</code> to its parent's list and merge the modified parent.</li>
</ul>
<p>If cascade is not configured, then you'd need to do:</p>
<ul>
<li>Set the parent of <code>Entity4</code>.</li>
<li>Persist the newly created instance <code>Entity4</code>.</li>
<li>Add <code>Entity4</code> to its parent's list and merge the modified parent.</li>
</ul>
<p>Now you may ask why must the parent entity of <code>Entity4</code> have its list updated and subsequently merged in either case? </p>
<p>That is to make sure that both sides of the association are updated correctly and properly point to one another. Its very likely given the scenario that the parent side of the association is already loaded into the persistence context, so adding the child to the database won't refresh and be visible to an already loaded entity unless its refreshed. The easiest solution in this case is to always modify both sides correctly.</p>
<pre><code>public class ParentEntity {
// add child to the parent entity, maintains association
public void addChild(ChildEntity child) {
if ( child.getParent() != null ) {
child.getParent().removeChild( child );
}
child.setParent( this );
children.add( child );
}
// remove child from parent, disassociates association
public void removeChild(ChildEntity child) {
if ( this.equals( child.getParent() ) ) {
child.setParent( null );
children.remove( child );
}
}
}
</code></pre>
<p>I usually find it helpful to expose helper methods like the above on my domain models so that my code doesn't need to be concerned with the associations required to be maintained. I also would likely make the setter for the parent entity's list private so that only Hibernate can use it if needed to force strict use of the <code>addChild</code> / <code>removeChild</code> methods.</p>

How to build a sandbox environment <p>Hi SecurityManager Experts out there ;-)</p>
<p>I have written a small plugin framework that loads plugins with separate isolated classloaders. For a successfull undeploy of a plugin it is important to make sure that no reference to classes loaded by the plugin classloader are held by the application.</p>
<p>There is a feature in Java called shutdown hook that enables client code to register a thread that is executed when the JVM was requested to shut down. This implies that potentially there will be references held by the JVM to a class loaded by the plugin classloader. </p>
<p>My first attempt was to install a SecurityManager that denies adding a shutdown hook. This totally works and denies all attempts to add shutdown hooks. The interesting thing is, that I realized, that it is not the plugin itself that wants to add a shutdown hook. The plugin just triggers the AWT/Swing internals (precise: <code>SunFontManager</code>) by loading a font. The <code>SunFontManager</code> in turn adds the shutdown hook to do some of it's internal handling when the JVM exits. I do not want to deny that the plugin loads a font (because it has to) and I do not want do deny the Java internals to add their stuff.</p>
<p>For me it seems that I would have to grant more permissions to the code (if the <code>sun.*|java.*|javax.*</code> package is in the stack trace..uuuhmm...ugly) than it would have normally. But this breaks the conventions of the security framework which assumes that client code cannot have more privileges than code that is calling it.</p>
<p>How can I distinguish that it is not the plugin code but the Java internals that wants to do something? Or is there any other way to make sure not to corrupt the internals by denying something?</p>
<h2>Example of what happens</h2>
<p>To make things clearer, here is what actually happens in my application. I have a custom SecurityManager installed that should deny <code>addShutdownHook</code> performed directly by plugins, but should not deny those calls if performed as a side-effect by Java internal classes.</p>
<pre>
Context: Calls:
----------------------------------------------
AppClassloader Application
|
PluginClassloader PluginObject.init()
|
AppClassloader Font.create()
|
AccessController.doPrivileged(...) {
Runtime.addShutdownHook(...)
}
</pre>
<p>The SecurityManager was installed using <code>System.setSecurityManager()</code> and does this:</p>
<pre><code>@Override
public void checkPermission(java.security.Permission perm) {
if (perm.getName().equals("shutdownHooks")) {
if (threadContextClassLoaderIsPluginClassLoader()) {
throw new SecurityException("Installing shutdown hooks is not allowed.");
}
}
}
</code></pre>
<p>Although the <code>addShutdownHook</code> is called inside a <code>doPrivileged</code>-block my <code>SecurityManager</code> is called. Am I missing something? Should I check for the privileged context myself?</p>
| <p>I found out that I was totally misunderstanding the Java security concept. I want to build a sandbox for plugin code so that it is always running in a restricted environment where I can control the permissions it has. The application should always run alongside with full access granted. </p>
<p>Here is how to build a sandbox for classes loaded by a separate classloader:</p>
<ol>
<li><strong>Use the default SecurityManager</strong> If you find yourself implementing your own <code>java.lang.SecurityManager</code> to allow or deny actions based on permissions you are probably doing wrong! You only need to install the default <code>java.lang.SecurityManager</code> by doing this <code>System.setSecurityManager(new SecurityManager());</code>. Now you get a working access control by using Java defaults.</li>
<li><p><strong>Grant all permissions to application</strong> The application that loads the plugins should get full access. This is because we trust ourselves. I solved this by starting my application with a policy file that grants all access. I think the policy file is needed on application start because the AppClassLoader needs to create the correct protection domains for the classes. Start the main application with the JavaVM argument <code>java.security.policy=<URL-TO-POLICY></code> where <code><URL-TO-POLICY</code> points to the following policy file:</p>
<p><code>grant {
permission java.security.AllPermission;
};</code> </p></li>
<li><p><strong>Custom policy implementation</strong> We need to install our custom policy after application startup. We want to separate the permissions for the main application (which runs with full access granted) and the plugins (which permissions we want to limit). The plugins should run in a sandbox with hand-picked permissions. To achieve this, here is the custom policy implementation:</p>
<pre><code>class SandboxPolicy extends Policy {
@Override
public PermissionCollection getPermissions(ProtectionDomain domain) {
// Decide if the plugin permissions are needed or full access can be granted using all permissions.
if (isPlugin(domain)) {
return pluginPermissions();
} else {
return applicationPermissions();
}
}
private boolean isPlugin(ProtectionDomain domain) {
// Identify the classloader of the protection domain
// The PluginClassLoader is assumed to be the one that loaded
// the plugin
return domain.getClassLoader() instanceof PluginClassLoader;
}
private PermissionCollection pluginPermissions() {
// Empty permissions = No permissions
// This is not the point to add plugin permissions
return new Permissions();
}
private PermissionCollection applicationPermissions() {
// Grant full access to the application
Permissions permissions = new Permissions();
permissions.add(new AllPermission());
return permissions;
}
}
</code></pre></li>
<li><p><strong>ProtectionDomains per Classloader</strong> The classloaders are responsible to create a <code>ProtectionDomain</code> for every source, code is loaded from. The protection domains specify the permissions that will be granted to the code. We have to modify the set of permissions the classloader adds to the protection domains. To do this, let your PluginClassloader extend the <code>java.security.SecureClassLoader</code>. Then override the method <code>java.security.SecureClassLoader.getPermissions(CodeSource)</code> in the following way: </p>
<pre><code>@Override
protected PermissionCollection getPermissions(CodeSource codeSource)
{
PermissionCollection pc;
// The SecureClassloader per default grants access to read resources from the source JAR.
// This is useful. Call super to get those permissions:
pc = super.getPermissions(codeSource);
// At this point you can extend permissions.
// For example grant read access to a file.
pc.add(new FilePermission("path\\file", "read"));
return (pc);
}

<p><strong>Note:</strong> See the policy implementation and have a look at my comment <code>// This is not the point to add plugin permissions</code>. The policy is asked by the <code>AccessController</code> to see if a permission can be granted. If permissions are added here, the information you can get from the caller are very limited. I woul not recommend to calculate and add any permissions here. The classloader is the point where you can add permissions based on the code source. I recommend to add permissions here. They become visible in the protection domains and you can easily observe what the AccessController is doing with those protection domains.</p>
<p><strong>Privileged actions</strong></p>
<p>There is another part in my question that I want to answer. </p>
<blockquote>
<p>The interesting thing is, that I realized, that it is not the plugin itself that wants to add a shutdown hook. The plugin just triggers the AWT/Swing internals (precise: SunFontManager) by loading a font.</p>
</blockquote>
<p>There are actions that will be performed as a side effect of plugin code. A class <code>org.plugin.A</code> can trigger the Swing/AWT internals to add a shutdown hook. In this case we do not want to deny this. The Java classes are in scope of the application and should get full access. The plugin code may be restricted and adding a shutdown hook directly should fail with <code>SecurityException</code>. This is a common use-case of <code>java.security.AccessController.doPrivileged(PrivilegedAction<T>)</code>. A privileged action makes sure that the <code>AccessController</code> will only take the protection domain of the last stack frame into account. AWT/Swing is adding its shutdown hook inside a privileged action and therefore is allowed to do so, because the protection domain of the classes performin this action where setup with full access permission. Please refer to any documentation of <code>java.security.AccessController</code> to learn more about privileged actions.</p>

sync threads to read different resources at exactly the same time <p>I have two cameras and this is important to read the frames with OpenCV exactly at the same time, I thought something like <code>Lock</code> but I cannot figure out the way I can implement this, I need some trigger to push and enable the threads to read frames, and then wait for another trigger hit, something like below:</p>
<pre><code>def get_frame(queue, cap):
while running:
if(read_frame):
queue.put(cap.read());
else:
# without this sleep this function just consumes unnecessary CPU time
time.sleep(some_time);
q = Queue.Queue()
# for every camera
for u in xrange(2):
t = threading.Thread(target=get_frame, args = (q, caps[u]))
t.daemon = True
t.start()
</code></pre>
<p>The problems with the above implementation are:</p>
<ol>
<li>I need the sleep time to be defined since I don't know the delay in between every frame read(i.e it might be long or short, depending on the calculation)</li>
<li>This does not enable me to read once for every trigger hit. </li>
</ol>
<p>So this approach won't work, Any suggestions?</p>
| <p>Consider getting FPS from VideoCapture. Also, note the difference between VideoCapture.grab and VideoCapture.retrieve frame. This is used for camera synchronization.</p>
<p>First call VideoCapture#grab for both cameras and then retrieve the frames. See <a href="http://docs.opencv.org/trunk/d8/dfe/classcv_1_1VideoCapture.html#ae38c2a053d39d6b20c9c649e08ff0146" rel="nofollow">docs</a>.</p>

What happened to VMDepot? <p>I know that bitnami has moved all his images to the Azure Marketplace, but there was others VM on vmdepot. Now there is no simple way to share virtual machines on Azure.</p>
| <p>As you mentioned, Microsoft Azure decide to removed their old VM Depot Marketplace and all the Bitnami Images have been moved to their new Marketplace: </p>
<p><a href="https://azure.microsoft.com/en-us/marketplace/" rel="nofollow">https://azure.microsoft.com/en-us/marketplace/</a>.</p>
<p>You can create your a virtual machine image for the Azure Marketplace and publish it following the guide below:</p>

Transpose result of hibernate query into list of POJOs <p>I got a generics class that contains runQuery method that has following code setup:</p>
<pre><code>public Object runQuery(String query) {
Query retVal = getSession().createSQLQuery(query);
return retVal.list();
}
</code></pre>
<p>I am trying to figure out how to transpose the returned values into a list of Check objects (List):</p>
<pre><code>public class Check {
private int id;
private String name;
private String confirmationId;
//getters and setters
}
</code></pre>
<p>Most queries that i run are actually stored procs in mysql. I know of native queries and resultTransforms (which if implemented would mean i have to change my generics and not after that).
Any ideas how i can accomplish this with current setup?</p>
| <p>You can find tutorials on ORMs ( <a href="http://stackoverflow.com/questions/7067860/what-is-object-relational-mappingorm-in-relation-to-hibernate-and-jdbc">What is Object/relational mapping(ORM) in relation to Hibernate and JDBC?</a> ). </p>
<p>Basically, you add annotation to your Check class to tell hibernate which java fields matches which DB field, make a JPQL (it looks like SQL) request and it gets your object and maps them from DB to POJO.</p>
<p>It's a broad subject, this is a good start: <a href="https://www.tutorialspoint.com/hibernate/hibernate_quick_guide.htm" rel="nofollow">https://www.tutorialspoint.com/hibernate/hibernate_quick_guide.htm</a>
It will require some configuration, but that's worth it. Here's one tutorial on annotation based configuration: <a href="https://www.tutorialspoint.com/hibernate/hibernate_annotations.htm" rel="nofollow">https://www.tutorialspoint.com/hibernate/hibernate_annotations.htm</a> but with less explanations on how ORM works (there's also EclipseLink as an ORM)</p>
<p>Else, you could make you're own mapper, which takes values from a <code>ResultSet</code>, and set them in your class. For a lot of reason, I would recommand using an ORM than this method (Except maybe if you have only one class that is stored in the DB, which I doubt).</p>

shopt -s autocd missing when inside tmux? <p>It's very strange. I have <code>shopt -s autocd</code> set within my <code>.bashrc</code> file and if I run <code>shopt -p</code> in my shell I can see that it's available (and set).</p>

| <p><code>tmux</code> creates a login shell by default for each new window/pane. This means <code>.bash_profile</code> (or possibly <code>.profile</code> or <code>.bash_login</code>, depending on the available files) is executed, not <code>.bashrc</code>. See the man page for information on the <code>default-shell</code> and <code>default-conmand</code> options.</p>

SourceTree install behaving strangely <p>Hi we are in the process of transitioning to Git/SourceTree/Bitbucket and are a bit new to this. I installed Source Tree on a colleagues machine and few funny things happen which I don't remember happening on mine.</p>
<ol>
<li>SourceTree didn't have a version of Git installed - so it gave us an embedded option which we installed but I was a bit confused by</li>
<li>There wasn't a default global git ignore we had to create one</li>
<li>We couldn't stash we had to explicitly set the username and email in the terminal before it would work and even then it didn't seem to stash properly</li>
</ol>
<p>I suspect I've done something wrong/different during the install and I was wondering whether anyone could shed any light on this? Perhaps during the setup process with Altassian/activating a licence? Cheers. </p>
| <p>I think this isn't really an issue, I reinstalled it and it started working. I've probably inadvertently done something without realizing it.</p>

SQL SUM() and ANGULAR.JS <p>I know how to connect, display, remove, add data from my database and display all of it on my website. Everthing works correctly. I see my results on my website and in my database. I do this with AngularJS, AJAX and PHP but my problem is I don't know how to dispaly MYSQL SUM() one of my column. For example this is my table in mysql and I would like to dispaly the total sum of the money column.</p>
<pre><code>id money
1 23
2 345
3 111

<p>This is what I got:</p>

<tr>
<td>{{ wcdrates.sumMoney }}</td>
</tr>
</table>
</code></pre>
<p>.................</p>
<p>I don't know If I should leave ng-repeat as it is or use something different instead. Anyway ng-repeat dosent'work. It shows me all results from money column not the total SUM.

Select left 4 characters without duplicates <p>I have a database table named <code>monthly</code>. One of the column names is <code>month</code>.</p>
<p>Inside <code>month</code>, there is these few datas - <code>201601, 201602, 201501, 201502</code>.</p>
<p>Now what I want to do is to get the first 4 characters from the LEFT (basically trying to just take the year value out) and display it without duplicates.</p>
<p>This is the mySQL code that I tried:</p>
<pre><code>SELECT LEFT(month,4) from monthly
</code></pre>
<p>This however is wrong. Can I know how do I write the query to get only the first 4 characters without any duplicate value? </p>
<p>So for this, the result should be just <code>2015, 2016</code>.</p>
| <pre><code>SELECT DISTINCT LEFT(month,4) AS `Year`
FROM monthly
</code></pre>

When to use static binding and when to use dynamic binding in Java? <p>Recently I am learning how to use Slf4j. And I know two new concepts:static binding and dynamic binding.In JCL(Jakarta Commons Logging) it use dynamic binding to choose the implementation while Slf4j is using static binding.
In this case we know Slf4j is more wise.But how about other case? </p>
<p>If we meet a problem that we can resolve it both in using static bingding and dynamic binding, then how we choose? Is there any basic rules?</p>
<p>My English is not very good.So I am not sure whether i have made it clear.If you have more question , please comment. </p>
<p>THX.</p>
| <p>Here : <a href="http://javarevisited.blogspot.com/2012/03/what-is-static-and-dynamic-binding-in.html" rel="nofollow">Link</a></p>
<p>Few important difference between static and dynamic binding</p>
<p>1) Static binding in Java occurs during Compile time while Dynamic binding occurs during Runtime.</p>
<p>2) private, final and static methods and variables uses static binding and bonded by compiler while virtual methods are bonded during runtime based upon runtime object.</p>
<p>3) Static binding uses Type(Class in Java) information for binding while Dynamic binding uses Object to resolve binding.</p>
<p>3) Overloaded methods are bonded using static binding while overridden methods are bonded using dynamic binding at runtime.</p>
<p><strong>Static Binding Example in Java</strong></p>
<pre><code> public class StaticBindingTest
{
public static void main(String args[])
{
Collection c = new HashSet();
StaticBindingTest et = new StaticBindingTest();
et.sort(c);
}
//overloaded method takes Collection argument
public Collection sort(Collection c)
{
System.out.println("Inside Collection sort method");
return c;
}
//another overloaded method which takes HashSet argument which is sub class
public Collection sort(HashSet hs)
{
System.out.println("Inside HashSet sort method");
return hs;
}
}
</code></pre>
<p>Output: Inside Collection sort method</p>
<p><strong>Example of Dynamic Binding in Java</strong></p>
<pre><code> public class DynamicBindingTest
{
public static void main(String args[])
{
Vehicle vehicle = new Car(); //here Type is vehicle but object will be Car
vehicle.start(); //Car's start called because start() is overridden method
}
}
class Vehicle
{
public void start()
{
System.out.println("Inside start method of Vehicle");
}
}
class Car extends Vehicle
{
@Override
public void start()
{
System.out.println("Inside start method of Car");
}
}
</code></pre>
<p>Output: Inside start method of Car</p>

How to use different middlewares for different paths in GO? <p>Hi I am using <a href="https://github.com/justinas/alice" rel="nofollow">justinas/alice</a>, and I want to create different middlewares based on paths. i.e if I have path1 and path2, I want to apply m1,m2,m3 for path 1 and m1,m2 for path 2</p>
<p>I tried:</p>
<ul>
<li>Creating two mux routers first: </li>
</ul>
<p><code>router := mux.NewRouter()
router2 := mux.NewRouter()</code></p>
<ul>
<li>Assign the paths to them:</li>
</ul>
<p><code>router.HandleFunc(path1,Func1)
router2.HandleFunc(path2,Func2)
</code></p>
<ul>
<li>Then I wanted to have something like this</li>
</ul>
<p><code>middlewares:=alice.New(m1,m2).Then(router2)
middlewaress:=middlewares.Append(middlewares)
</code>
- Then:</p>
<pre><code>if err := http.ListenAndServe(fmt.Sprintf(":%d", sconf.Server.Port), middlewaress); err != nil {
}
</code></pre>
<p>how can I do something like this?</p>
| <p>You need to let set the handlers for <code>router</code> and <code>router</code> to the returned chain from <code>alice</code>.</p>
<pre><code>// define routers
router := mux.NewRouter() // assuming this is gorilla mux
router2 := mux.NewRouter()
// create alice chains
chain1 := alice.New(m1, m2, m3).Then(func1)
chain2 := alice.New(m1, m2).Then(func2)
// set chains as path handlers
router.HandleFunc(path1, chain1)
router2.HandleFunc(path2, chain2)

App Crash on iPad after update to XCode 8 <p>I updated XCode like MacOS suggested to XCode 8. I run my App on Simulator and it worked fine. But when i tried to run the App on my iPad the App crashed unexpected. <br>
I was looking for the problem but couldn't find any place because it still runs on simulator. But then installed the older XCode 7.3.1 again and the app runs again on my iPad.<br>

Laravel Nested relationships using dot syntax querying each level <p>the goal here is to have my menu model create a tree with each related child and the child's related Page.</p>
<p>I'm generating a tree with my model like this...</p>
<pre><code> public static function tree()
{
return static::with(implode('.', array_fill(0, 100, 'children')))->with('Pages')->where('parent_id', '=', 0)->get();
}
</code></pre>
<p>But the problem comes with getting each childs related Page.
I've tried this...</p>
<pre><code> return static::with([implode('.', array_fill(0, 100, 'children')) => function($query) {
$query->with('Pages');
}])->with('Pages')->where('parent_id', '=', $id)->get();
</code></pre>
<p>and adding the eager loading query didn't seem to work. i think maybe using the dot sytax and querying it only queries the last one? I'm not sure on that.</p>
<p>I need to query each level of the query but i don't know how.
any help would be greatly appreciated!</p>
| <p>UPDATE: it seems I've managed to fix this problem by doing this...</p>
<pre><code>public static function genRelationalArray()
{
$arr = [implode('.', array_fill(0, 100, 'children'))];
for($i = 0; $i < 10; $i++) {
$item = 'children.Pages';
$arr[] = $item;
$item = 'children.'. $item;
}
return $arr;
}
public static function treeFromId($id)
{
$childArr = static::genRelationalArray();
return static::with($childArr)->with('Pages')->where('parent_id', '=', $id)->get();
}
</code></pre>
<p>but if there is a shorter more efficient way of doing this please post :)</p>

<p>This works in the first page only but when I navigate to second page the controller url changes to index/2 r any other page number I get users rows without data orders though if I print_r orders above the table I get correct orders</p>
| <p>you can reduce the code a little but in controller like this:</p>
<pre><code>$this->data['users'] = $users; // correct data no problem here
$user_orders = array();
foreach ($users as $user){
$user_orders[$user->user_id] = $this->myMmodel>get_orders($user->user_id); //make user_id as key so that you can access easily for each user
}
$this->data['orders'] = $user_orders;
</code></pre>
<p>Then in view, you can access orders of each user inside the foreach loop like this:</p>
<p>$orders[$user->user_id]</p>
<p>as it is also an array, you have to run loop to create order rows for each user:</p>
<pre><code>$order = array(); //empty the variable before each loop
foreach($orders[$user->user_id] as $order){
echo '<tr><td>'.$order->id.'</td>'.....//more columns like this
}

Escape backslash in Python parameterized MySQL query <p>I am working on excel files and database storaging, precisely I am storaging excel data to MySQL database. At some point I am executing this query:</p>
<pre><code>query_for_id = ''' SELECT id FROM attivita WHERE attivita = '{0}' '''.format(attivita)
</code></pre>
<p>And when I print the query result I get this:</p>
<p>' SELECT id FROM attivita WHERE attivita = \\'Manutenzione\\' '</p>
<p>When it tries to match 'attivita' with the right value, taken from the excel, I got errors because of the '\\'.</p>
<p>I tried changing the triple quotes from " " " to ' ' ', as well as using <code>connection.escape_string()</code>, but I didn't solve the problem. Can anyone help me figuring out the problem? Thank you in advance.</p>
| <p>I think that in your case better to use arguments to execute</p>
<pre><code>query_for_id = ''' SELECT id FROM attivita WHERE attivita = %(attivita)s '''
cursor.execute(query_for_id, { 'attivita': attivita })

R - string manipulation and extraction <p>I have a string <code>strEx <- "list(A, B, C, D)"</code> that I would like to store as a character vector:</p>
<pre><code>[1] "A" "B" "C" "D"
</code></pre>
<p>I'm not very good at regex (might be overkill as well, but I will need more of it in the future) which is probably part of my problem. I have a solution that I feel is too much code/bad form.</p>
<p>It gives me what I want in the end but I still need to split it on commas and flatten it. I just feel this is a too crude a way to go about it. Anyone have a prettier solution?</p>
<pre><code>d <- gsub(".*\\((.*)\\).*", "\\1", strEx)
d1 <- unlist(tstrsplit(d, ", ", type.convert = TRUE, fixed = TRUE))
</code></pre>
| <p>You could parse the expression like this:</p>
<pre><code>#parse the expression
pEx <- parse(text = strEx)[[1]]
</code></pre>
<p>Expressions are actually lists of symbols and can be treated as such. Here we turn everything except <code>list</code> into characters:</p>
<pre><code>vapply(pEx[-1], as.character, FUN.VALUE = "")
#[1] "A" "B" "C" "D"
</code></pre>
<p>However, if you need to parse a string (which is what you propose as a solution using regex too), some preceding step should usually be improved. You should not have an expression that needs to be parsed.</p>
<p>See this:</p>

fortune(106)
#If the answer is parse() you should usually rethink the question.

Issue with transitioning between activities containing adapters sharing the same data set <p>Given 2 activities, A starts B for result.</p>
<p>Both activities have structures (A: RecyclerView, B: ViewPager) and adapters which connect to the same data set, stored in the Application object.</p>
<p>B finishes and posts the result back to A.</p>
<p>A gets the result on onActivityResult() and in the body of the function alters the data set (removes one element).</p>
<p>Issue is that later (after debugger exits my code) I get a crash in B saying:</p>

Get data from scope to another scope within one controller angularjs <p>I'm absolutely beginner in AngularJS. So, I'll be really appreciate for any help. I'm trying to build an app with charts in it using Ionic and Angular-nvD3 lineChart. I have data in json file. So, I've made factory and used getData(), $scope and service. I need one line chart with many data points on it. But output looks like every point is separate from another. I thought maybe it's because of $scope and getData function. Maybe there is some kind of loop in it, which separate data.

How do I customize the URL that Ember RESTAdapter calls? <p>In our Ember application, I have 3 different models:</p>
<ul>
<li>organizations</li>
<li>users</li>
<li>issues</li>
</ul>
<p>Issues are created by users who belong to an organization. Both <code>organizations</code> and <code>users</code> have an <code>issues</code> array with a bunch of issue IDs that belong in the <code>issues</code> model. For example, this is what the <code>users</code> model looks like:</p>
<pre><code>// app/models/users.js
export default DS.Model.extend({
name: DS.attr('string'),
email: DS.attr('string'),
belongsTo: DS.belongsTo('organizations'),
issues: DS.hasMany('issues')
});
</code></pre>
<p>We have two APIs to view a list of all issues:</p>
<ul>
<li><code>GET /users/:userId/issues</code> - This API gets all the issues created by the user</li>
<li><code>GET /organizations/:organizationId/issues</code> - This API gets all the issues created by users that belong to this organization</li>
</ul>
<p>The issue is, when I call <code>this.store.findAll('issues');</code>, the Ember RESTAdapter calls <code>GET /issues</code> by default. I can't figure out a way to get the RESTAdapter to call any of the URLs above. I can't use <code>this.store.findRecord('issues', 1);</code> because that calls a specific issue by ID like <code>GET /issues/:issueId</code>. How can I get the RESTAdapter to call the above URLs without having to manually make an AJAX request and push the API response to Ember Data?</p>
| <p>You need to customize your adapter (you can have an adapter per-model if you want, as far as I know).</p>
<p>In your specific example I think you want to customize the <a href="http://emberjs.com/api/data/classes/DS.JSONAPIAdapter.html#method_urlForFindAll" rel="nofollow"><code>urlForFindAll</code></a> method.</p>
<pre><code>// maybe in app/organization/adapter.js (if using pods for a model specific adapter)
urlForFindAll(modelName) {
return 'urlYouWantToUseWithOrganizations';
}
</code></pre>
<p>A good article on this situation is on <a href="https://emberigniter.com/fit-any-backend-into-ember-custom-adapters-serializers/" rel="nofollow">Ember Igniter</a></p>

What's are the types of JOINS will support in Mysql?Is there any possible way to do this? <ul>
<li><p>How to do full joins in mysql.?and what are the types of joins will
support in mysql.
i'm beginner in mysql please help me solve this issue...</p>
<p>Thank you!</p></li>
</ul>
| <p>Before asking this question, I am assuming that you have not searched the net for anything at all, let alone MySQL documentation. Because I have asked stupid questions in the past (without researching enough), I am going to answer this one. By the way, this is a habit you must work upon. You should search for material, read and try solutions to your problems before coming to Stack Exchange.</p>
<p>Here's a snapshot from <a href="http://dev.mysql.com/doc/refman/5.7/en/join.html" rel="nofollow">Official MySQL Documentation</a>:</p>
<p><a href="http://i.stack.imgur.com/1DjoG.png" rel="nofollow"><img src="http://i.stack.imgur.com/1DjoG.png" alt="From MySQL Documentation"></a></p>
<p>Apart from this, here are a few links that would help you understand JOINs, in general:</p>
<ol>
<li><a href="https://blog.codinghorror.com/a-visual-explanation-of-sql-joins/" rel="nofollow">Coding Horror's Visual Explanation of JOINs</a></li>
<li><a href="http://stackoverflow.com/questions/17946221/sql-join-and-different-types-of-joins">Stack Overflow - SQL JOINs and their types</a></li>
<li><a href="http://stackoverflow.com/questions/38549/what-is-the-difference-between-inner-join-and-outer-join">One of the most popular posts on Stack Overflow - Difference between Inner and Outer JOINs</a></li>
</ol>
<p>I think this would suffice for the basic knowledge of JOINs. You'd have to read more about what JOIN to use when - based on the data you want to fetch and also how your database management system (in this case, MySQL) <a href="https://dev.mysql.com/doc/internals/en/optimizer-determining-join-type.html" rel="nofollow">works with JOINs internally to optimize performance</a>.</p>

Ordering Azure Active Directory Graph Results by Created Date <p>Does anyone know how to order the results of a query to the Azure AD Graph API using the nuget assembly (<a href="https://www.nuget.org/packages/Microsoft.Azure.ActiveDirectory.GraphClient/" rel="nofollow">https://www.nuget.org/packages/Microsoft.Azure.ActiveDirectory.GraphClient/</a>) by "Created Date" (i.e. when the user was created in the directory?</p>
<p>I can't find any documentation about a property which would contain this. Is the result set automatically ordered in this way?</p>
| <p>There is a restriction at the moment on the '$orderby' expressions that can be specified for a Graph API query. From the <a href="https://msdn.microsoft.com/library/azure/ad/graph/howto/azure-ad-graph-api-supported-queries-filters-and-paging-options" rel="nofollow">documentation</a> - </p>
<blockquote>
<p>The following restrictions apply to $orderby expressions:</p>
</blockquote>
<ul>
<li><blockquote>
<p>Two sort orders are currently supported: DisplayName for User and Group objects, and UserPrincipalName for User objects. The default sort order for users is by UserPrincipalName.</p>
</blockquote></li>
</ul>
<p>So even if the 'Created Date' was exposed as property on the User I doubt the query will work.</p>

<blockquote>
<p>Bundles must continue to support any devices previously supported.</p>
</blockquote>
<p><strong>The only option</strong> for you is to create a new bundle ID and submit your app with it.</p>
<blockquote>
<p>Removing your app from the store, and uploading the update with a
different bundle ID, will allow you to narrow the range of devices
your update supports. However the update will be listed on the store
as a separate app.</p>

How to access the value of a ctypes.LP_c_char pointer? <p>I have defined a struct : </p>
<pre><code>class FILE_HANDLE(Structure):
_fields_ = [
("handle_bytes", c_uint),
("handle_type", c_int),
("f_handle", POINTER(c_char))
]
</code></pre>
<p>The struct is initialised :</p>
<pre><code>buf = create_string_buffer(f_handle.handle_bytes)
fh = FILE_HANDLE(c_uint(8), c_int(0), buf)
</code></pre>
<p>I am passing it by reference to a function that populates it.</p>
<pre><code>ret = libc.name_to_handle_at(dirfd, pathname, byref(fh), byref(mount_id), flags)
</code></pre>
<p>I can check with strace that the call works, but I have not been able to figure out how to access the value of fh.f_handle</p>
<p>fh.f_handle type is <code><ctypes.LP_c_char object at 0x7f1a7ca17560></code><br>
fh.f_handle.contents type is <code><ctypes.LP_c_char object at 0x7f1a7ca17560></code> but I get a SIGSEGV if I try to access its value.<br>
How could I get 8 bytes from f_handle into a string or array ?</p>
| <p>fh.f_handle is shown as LP_c_char because you defined the struct that way.</p>
<pre><code>buf = create_string_buffer(8)
print type(buf)
fh = FILE_HANDLE(c_uint(8), c_int(0), buf)
print type(fh.f_handle)
</code></pre>
<p>Will output</p>
<pre><code><class 'ctypes.c_char_Array_8'>
<class 'ctypes.LP_c_char'>
</code></pre>
<p>You have defined your struct to accept a pointer to a c_char. So when you try to access fh.f_handle it will expect the value to be a memory address containing the address to the actual single c_char.</p>
<p>But by trying to input a c_char * 8 from the string buffer it will convert the first part of your buffer to a pointer.</p>
<p>Python tries to dereference your char[0] which means that it will look for a memory address with the value of the character you have defined in char[0]. That memory address is not valid, so your interpreter will signal a SIGSEGV.</p>
<p>Now to create a class which properly handles a variable length buffer is quite difficult. An easier option is to pass the buffer as an opaque handle, to access it afterwards you need to cast it back to a char array.</p>
<p>Example:</p>
<pre><code>class FILE_HANDLE(Structure):
_fields_ = [
("handle_bytes", c_uint),
("handle_type", c_int),
("f_handle", c_void_p)
]
buf = create_string_buffer(8)
buf = cast(buf, c_void_p)
fh = FILE_HANDLE(c_uint(8), c_int(0), buf)
f_handle_value = (c_char * fh.handle_bytes).from_address(fh.f_handle)
</code></pre>

<p>Thank you.</p>
| <p>Assuming the <code>1.0</code> is the project version in your <code>pom.xml</code> file, if you don't have the <code>build</code> element in your <code>pom.xml</code> add the following as a child of <code>project</code> element:</p>
<pre><code><build>
<finalName>projectmvn-web</finalName>
</build>
</code></pre>
<p>If you already have the <code>build</code> element add the <code>filalName</code> element as follows:</p>
<pre><code><build>
<finalName>projectmvn-web</finalName>
// the rest goes here
</build>
</code></pre>
<p>With this setting Maven should create <code>projectmvn-web.war</code> in the <code>target</code>folder, i.e., without the version information on the filename.</p>

Wordpress child theme style.css not working <p>I have created a file structure in the same format as my parent theme. My parent theme is called Alpine and within Alpine there is a functions.php and style.css file. There do not appear to be any additional style.css files.</p>
<p>I have created a directory called Alpine-child and within that I have created a functions.php and style.css file.</p>

| <p>Take a look at your <code><head></code> tag. More importantly look at the order of your stylesheets.</p>
<p>The styles from your child theme are being added first and then all the styles from your parent theme. This will cause the styles from the parent theme to override your child theme styles.</p>
<p>You can change the priority of your <code>my_theme_enqueue_styles</code> function to run after the parent by using the third parameter of <a href="https://developer.wordpress.org/reference/functions/add_action/" rel="nofollow">add_action</a>. This will enqueue your child theme styles last and allow the CSS to work as expected.</p>
<pre><code><?php
add_action( 'wp_enqueue_scripts', 'my_theme_enqueue_styles', 11 );
function my_theme_enqueue_styles() {
wp_enqueue_style( 'child-style', get_stylesheet_uri() );

Mod Rewrite: Leading slash followed by parameter after domain name <p>I'm trying to create a rewrite rule that changes a URLwith parameters into just a forward slash followed by a parameter.</p>
<p>The RewriteRule:
<code>RewriteRule ^(.*)$ send.php?url=$1&name=&submit=submit [NC,L]</code></p>
<p>The above rule should then work for the URL:
<code>example.com/google.com</code></p>
<p>But although the URL <code>example.com/google.com</code> remains in the browser bar and I do not get a 404 or 500 server error, instead of adding google.com as a parameter, <code>send.php</code> is added as the URL parameter instead.</p>
<p>The URL should go to:
<code>send.php?url=google.com&name=&submit=submit</code>
But it currently goes to:
<code>send.php?url=send.php&name=&submit=submit</code></p>
<p>Interestingly if I change the <code>RewriteRule</code> slightly, everything works fine.
Working <code>RewriteRule</code>
<code>RewriteRule ^send/(.*)$ /send.php?url=$1&name=&submit=submit [NC,L]</code></p>
<p>Here's a copy of the log for both working and not working versions of the <code>RewriteRule</code>.<br>

<p>Looking at the log it gets it correct to begin with: <code>url=google.com</code>, but then further along changes to <code>url=send.php</code></p>
<p>So in summary, how can I turn this URL: <code>example.com/send.php?url=google.com&name=&submit=submit</code>
into this URL: <code>example.com/google.com</code></p>
| <p>Try with:</p>
<pre><code>RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ send.php?url=$1&name=&submit=submit [NC,L]
</code></pre>
<p>This way you avoid to rewrite existing files and directories.</p>
<p>With <code>-f</code> you test for files, and with <code>-d</code> for directories.

React-Native Fresh Install Compile Error <p>I've created a few react-native projects, and since updating to Sierra OSX and Xcode 8, upon opening each project, I get the error:</p>
<p><code>Application AppName has not been registered. This is either to due to a require() error during initialisation or a failure to call AppRegistry.registerComponent.</code></p>
<p>I've gone back to basics, uninstalled and reinstalled node, reinstalled latest react-native, created a fresh init, and still get the error. I've looked up and removed the custom-compiler-flags, as suggested <a href="https://github.com/facebook/react-native/issues/8584#issuecomment-236366222" rel="nofollow">here</a>.</p>
<p>This is a real problem, if anyone has any insights I would be very appreciative!</p>
| <p>I was having this error last night! All I did was to remove the node_modules, install then again and run the app again, it worked. â Crysfel</p>

What is NavigationServices.FirstOrDefault() of Template10 navigation service? <p>I want to navigate between pages in Template10. From the documentation,
<a href="https://github.com/Windows-XAML/Template10/wiki/Services#navigationservice" rel="nofollow">https://github.com/Windows-XAML/Template10/wiki/Services#navigationservice</a>, the example is as follow</p>
<blockquote>
<p>// from inside any window var nav =
WindowWrapper.Current().NavigationServices.FirstOrDefault();
nav.Navigate(typeof(Views.DetailPage), this.Value);</p>
</blockquote>
<p>Unfortunately WindowWrapper.Current().NavigationServices.FirstOrDefault() does not exist. What FirstOrDefault actually means?</p>
<p>Also, how do I navigate to other page from page.xaml.cs?</p>
| <p><code>FirstOrDefault()</code> is an extension method provided by LINQ. You need to add the line:</p>
<pre><code>using System.Linq;
</code></pre>
<p>at the top of your file to get it.</p>

How to insert a attachment and update a custom field in a post type in Wordpress <p>I have a custom post type named ['notifications'] with a custom field named ['attachment'] for all posts in ['notifications'] .</p>
<ul>
<li>I want a user to upload a attachment into the library from the front end</li>
<li>If upload is successful</li>
<li>Get the filename of the attachment </li>
<li>Then update a post in custom post type ['notifications'] by its id </li>
<li>Update custom field ['attachment'] in a post to filename</li>
</ul>
<p>The meta_key for the custom field is ['_ct_text_57fc8ec4573cd']</p>
<p>This is what I have so far</p>
<p><strong>FOR THE FRONT END</strong></p>
<pre><code><?php
if (isset($_POST['upload'])) {
if (!empty($_FILES)) {
$file = $_FILES['file'];
$attachment_id = upload_user_file($file);
}
}
?>
<form action="" enctype="multipart/form-data" method="post">
<input name="file" type="file">
</form>
</code></pre>
<p><strong>INSIDE FUNCTIONS.PHP</strong></p>
<pre><code>function upload_user_file($file = array()) {
require_once(ABSPATH. 'wp-admin/includes/admin.php');
$file_return = wp_handle_upload($file, array('test_form' => false));
if (isset($file_return['error']) || isset($file_return['upload_error_handler'])) {
return false;
} else {
$filename = $file_return['file'];
$post_ID_attachment = 33;
$attachment = array('post_mime_type' => $file_return['type'],
'post_title' => $post_ID_attachment,
'post_content' => '',
'post_status' => 'inherit',
'guid' => $file_return['url']
);
$attachment_id = wp_insert_attachment($attachment, $file_return['url']);
require_once(ABSPATH. 'wp-admin/includes/image.php');
$attachment_data = wp_generate_attachment_metadata($attachment_id, $filename);
wp_update_attachment_metadata($attachment_id, $attachment_data);

return $attachment_id;
}
/* UPDATE ATTACHMENT BELOW*/
update_post_meta($post_ID_attachment, '_ct_text_57fc8ec4573cd', $filename);
}
return false;
}
</code></pre>
<p>Not sure if I am doing it correctly.
The code above inserts attachment successfully but it is not updating the custom field in post type ['notifications']</p>
| <p>You have a return statement in your function, before <code>update_post_meta</code> query. Try following code:</p>
<pre><code>function upload_user_file($file = array()) {
require_once(ABSPATH. 'wp-admin/includes/admin.php');
$file_return = wp_handle_upload($file, array('test_form' => false));
if (isset($file_return['error']) || isset($file_return['upload_error_handler'])) {
return false;
} else {
$filename = $file_return['file'];
$post_ID_attachment = 33;
$attachment = array('post_mime_type' => $file_return['type'],
'post_title' => $post_ID_attachment,
'post_content' => '',
'post_status' => 'inherit',
'guid' => $file_return['url']
);
$attachment_id = wp_insert_attachment($attachment, $file_return['url']);
require_once(ABSPATH. 'wp-admin/includes/image.php');
$attachment_data = wp_generate_attachment_metadata($attachment_id, $filename);
wp_update_attachment_metadata($attachment_id, $attachment_data);
/* UPDATE ATTACHMENT BELOW*/
update_post_meta($post_ID_attachment, '_ct_text_57fc8ec4573cd', $filename);
if (0 < intval($attachment_id)) {
return $attachment_id;
}
}
return false;
}
</code></pre>
<p>Also I'm not sure you need these <code>require_once</code>-s in your code, since it in <code>function.php</code>, everything should be loaded.</p>

Update nested structure of maps and vectors <p>I have a map with a vector of map like this:</p>
<pre><code>{:tags ["type:something" "gw:somethingelse"],
:sources [{:tags ["s:my:tags"],
:metrics [{:tags ["a tag"]}
{:tags ["a noether tag" "aegn"]}
{:tags ["eare" "rh"]}]}]}
</code></pre>
<p>Note that there can be multiple sources, and multiple metrics.</p>
<p>Now I want to update the <code>:metrics</code> with an <code>id</code> by looking at the value of the tags. </p>
<p>Example: if <code>["a tag"]</code> matches with for example id 1, and <code>["a noether tag" "aegn"]</code> with id 2 I want the updated structure to look like this:</p>
<pre><code>{:tags ["type:something" "gw:somethingelse"],
:sources [{:tags ["s:my:tags"],
:metrics [{:tags ["a tag"]
:id 1}
{:tags ["a noether tag" "aegn"]
:id 2}
{:tags ["eare" "rh"]}]}]}
</code></pre>
<p>I made a function <code>transform</code> that can convert a tag to an id. E.g, <code>(transform "a tag")</code> returns 1.</p>
<p>Now, when I try do add the ids with a for-comprehension I miss the old structure (only the inner ones get returned) and with <code>assoc-in</code> I have to know the indices upfront.</p>
<p>How can I perform this transformation elegantly?</p>
| <p>i would start bottom up, making transformation function for <code>:tags</code> entry, then for <code>:metrics</code> and then for <code>:sources</code>. </p>
<p>let's say our transform function produces ids just by counting tags (just for illustration, it could be easily changed later):</p>
<pre><code>(defn transform [tags] (count tags))
user> (transform ["asd" "dsf"])
;;=> 2
</code></pre>
<p>then apply transformation the metric entry:</p>
<pre><code>(defn transform-metric [{:keys [tags] :as m}]
(assoc m :id (transform tags)))
user> (transform-metric {:tags ["a noether tag" "aegn"]})
;;=> {:tags ["a noether tag" "aegn"], :id 2}
</code></pre>
<p>now use <code>transform-metric</code> to update source entry:</p>
<pre><code>(defn transform-source [s]
(update s :metrics #(mapv transform-metric %)))
user> (transform-source {:tags ["s:my:tags"],
:metrics [{:tags ["a tag"]}
{:tags ["a noether tag" "aegn"]}
{:tags ["eare" "rh"]}]})
;;=> {:tags ["s:my:tags"],
;; :metrics [{:tags ["a tag"], :id 1}
;; {:tags ["a noether tag" "aegn"], :id 2}
;; {:tags ["eare" "rh"], :id 2}]}
</code></pre>
<p>and the last step is to transform the whole data:</p>
<pre><code>(defn transform-data [d]
(update d :sources #(mapv transform-source %)))
user> (transform-data data)
;;=> {:tags ["type:something" "gw:somethingelse"],
;; :sources [{:tags ["s:my:tags"],
;; :metrics [{:tags ["a tag"], :id 1}
;; {:tags ["a noether tag" "aegn"], :id 2}
;; {:tags ["eare" "rh"], :id 2}]}]}
</code></pre>
<p>so, we're done here. </p>
<p>Now notice that <code>transform-data</code> and <code>transform-source</code> are almost identical, so we can make an utility function that generates such updating functions:</p>
<pre><code>(defn make-vec-updater [field transformer]
(fn [data] (update data field (partial mapv transformer))))
</code></pre>
<p>with this function we can define deep transformations like this:</p>
<pre><code>(def transformer
(make-vec-updater
:sources
(make-vec-updater
:metrics
(fn [{:keys [tags] :as m}]
(assoc m :id (transform tags))))))

;; :metrics [{:tags ["a tag"], :id 1}
;; {:tags ["a noether tag" "aegn"], :id 2}
;; {:tags ["eare" "rh"], :id 2}]}]}
</code></pre>
<p>and based on this transformer construction approach we can make a nice function to update the values in vectors-of-maps-of-vectors-of-maps-of-vectors... structures, with arbitrary nesting level:</p>
<pre><code>(defn update-in-v [data ks f]
((reduce #(make-vec-updater %2 %1) f (reverse ks)) data))
user> (update-in-v data [:sources :metrics]
(fn [{:keys [tags] :as m}]
(assoc m :id (transform tags))))
;;=> {:tags ["type:something" "gw:somethingelse"],
;; :sources [{:tags ["s:my:tags"],
;; :metrics [{:tags ["a tag"], :id 1}
;; {:tags ["a noether tag" "aegn"], :id 2}
;; {:tags ["eare" "rh"], :id 2}]}]}
</code></pre>
<p><strong>UPDATE</strong></p>
<p>in addition to this manual approach, there is a fantastic lib called <a href="https://github.com/nathanmarz/specter" rel="nofollow">specter</a> out there, that does exactly the same thing (and much more), but is obviously more universal and usable:</p>
<pre><code>(require '[com.rpl.specter :as sp])
(sp/transform [:sources sp/ALL :metrics sp/ALL]
(fn [{:keys [tags] :as m}]
(assoc m :id (transform tags)))

2 separate controllers for the same end point in html and json or a single one? <p>I have the end points "/customers" and "/api/v1/customers", in html and json respectively for a list of customers. Do I have to create 2 different controllers and thus actions for them? Or can I return html or json from a single controller and action depending a requested format: html or json? Note that for "/api/v1/customers" I need authentication via an Api Key.</p>
| <p>You can have one controller and action for both endpoints, but I would advise against it.</p>
<p>You mentioned that those controllers need to do different stuff, so instead of adding stuff like "if json then check api key" make two separate controllers and extract common code of getting all the customers.</p>
<p>There is a great talk about untangling business logic from http interface: <a href="http://www.elixirconf.eu/elixirconf2016/lance-halvorsen" rel="nofollow">http://www.elixirconf.eu/elixirconf2016/lance-halvorsen</a> Getting a list of customers might be out of your controllers, so at the end you will have two controllers like this:</p>
<pre><code>defmodule MyApp.Api.CustomersController do
plug MaApp.ApiAuth #plug for checking api key
def index(conn, params) do
...
customers = ActualLogic.get_customers()
...
end
end
def MyApp.CustomersController do
plug MyApp.UserAuth #for example checks if user is logged in
def index(conn, params) do
...
customers = ActualLogic.get_customers()
...
end
end
</code></pre>
<p>At the end your controller does not perform any logic, it calls something else to do the job and action is responsible only for web stuff like parsing params, authentication via api key, session cookies and translating end result to json/html.</p>

The two generate random numbers and their product is different <p>So im creating a program that generate 2 random numbers and need to multiply them:</p>
<pre><code>public static int thenumber(){
int number1=(int)(Math.random()*10+1);
return number1;
}
public static int thenumber2(){
int number2=(int)(Math.random()*10+1);
return number2;
}
</code></pre>
<p>and solve it in :</p>
<pre><code>public static int thefusion(){
int demi =thenumber() * thenumber2();
return demi;
}
</code></pre>
<p>My problem is when i run it the product of two number is Different
ex: 7 * 4 = 24</p>
| <p>A complete code example would be nice (see <a href="http://stackoverflow.com/help/mcve">How to create a Minimal, Complete, and Verifiable example</a>), but let me guess: You are first seeing the two random numbers (from printing them or some other way). Then you call your method. The method draws two <em>new</em> random numbers from <code>thenumber()</code> and <code>thenumber2()</code>. Thatâs the point in (pseudo-)random numbers, you donât the same number each time. So if you drew the numbers 7 and 4 the first time, maybe next time you get 3 and 8, so the product is 24.</p>
<p>There are a couple of possible solutions:</p>
<ol>
<li>When calling <code>thenumber()</code> and <code>thenumber2()</code>, assign the results to two variables. Now you can see which numbers you got. Pass those two numbers into your <code>thefusion</code> method, and it should calculate the expected product.</li>
<li>Rather than <code>Math.random()</code> use the <code>Random</code> class and instantiate it with a known seed. Draw the two numbers from it and inspect them. Make a new <code>Random</code> instance from the same seed and have <code>thefusion()</code> use it. Now it will draw the same two numbers, and you will get the product you expected.</li>
</ol>

Matlab - Scale down an image using an average of four pixels <p>I have just started learning image-processing and Matlab and I'm trying to scale down an image using an average of 4 pixels. That means that for every 4 original pixels I calculate the average and produce 1 output pixel.
So far I have the following code:</p>
<pre><code>img = imread('bird.jpg');
row_size = size(img, 1);
col_size = size(img, 2);
res = zeros(floor(row_size/2), floor(col_size/2));
figure, imshow(img);
for i = 1:2:row_size
for j = 1:2:col_size
num = mean([img(i, j), img(i, j+1), img(i+1, j), img(i+1, j+1)]);
res(round(i/2), round(j/2)) = num;
end
end
figure, imshow(uint8(res));
</code></pre>
<p>This code manages to scale down the image but it converts it to grayscale.
I understand that I probably have to calculate the average of the <strong>RGB</strong> components for the output pixel but I don't know how to access them, calculate the average and insert them to the result matrix. </p>
| <p>In Matlab, an RGB image is treated as a 3D array. You can check it with:</p>
<pre><code>depth_size = size(img, 3)
depth_size =
3
</code></pre>
<p>The loop solution, as you have done, is explained in <a href="http://stackoverflow.com/a/39976574/6469393">Sardar_Usama's answer</a>. However, in Matlab it is recommended to avoid loops whenever you want to gain speed.</p>
<p>This is a vectorized solution to scale down an RGB image by a factor of <code>n</code>:</p>
<pre><code>img = imread('bird.jpg');
n = 2; % n can only be integer
[row_size, col_size] = size(img(:, :, 1));
% getting rid of extra rows and columns that won't be counted in averaging:
I = img(1:n*floor(row_size / n), 1:n*floor(col_size / n), :);
[r, ~] = size(I(:, :, 1));
% separating and re-ordering the three colors of image in a way ...
% that averaging could be done with a single 'mean' command:
R = reshape(permute(reshape(I(:, :, 1), r, n, []), [2, 1, 3]), n*n, [], 1);
G = reshape(permute(reshape(I(:, :, 2), r, n, []), [2, 1, 3]), n*n, [], 1);
B = reshape(permute(reshape(I(:, :, 3), r, n, []), [2, 1, 3]), n*n, [], 1);
% averaging and reshaping the colors back to the image form:
R_avg = reshape(mean(R), r / n, []);
G_avg = reshape(mean(G), r / n, []);
B_avg = reshape(mean(B), r / n, []);
% concatenating the three colors together:
scaled_img = cat(3, R_avg, G_avg, B_avg);
% casting the result to the class of original image
scaled_img = cast(scaled_img, 'like', img);
</code></pre>
<h3>Benchmarking:</h3>
<p>If you want to know why vectorized solutions are more popular, take a look at how long it takes to process an RGB 768 x 1024 image with the two methods:</p>
<pre><code>------------------- With vectorized solution:
Elapsed time is 0.024690 seconds.
------------------- With nested loop solution:
Elapsed time is 6.127933 seconds.
</code></pre>
<p>So there is more than 2 orders of magnitude difference of speed between the two solutions.</p>

Is there a way to add custom keyboard shortcuts to Vim for running numerous commands? <p>I'm having the following issue - whenever I finish writing some C++ code in Vim and want to compile and run it, I have to:</p>
<ol>
<li>Exit insert mode</li>
<li>Save the file using the command <code>:w</code></li>
<li>Write <code>:! g++ *.cpp -o programName; ./programName</code> in order to compile and run at once</li>
</ol>
<p>After inputting the last two commands once, I obviously make use of the upper arrow key on the keyboard to get the last few commands instead of writting them down again and again on future compilations and runs. </p>
<p>But it's still kind of slow to me. So I was wondering if there's some sort of way to maybe create a keyboard shortcut which inputs these last two commands or even does all the three things at once!</p>
| <p>You can use <code>map</code> to map keys to commands. <code>nmap</code> for normal mode, <code>imap</code> for insert mode etc</p>
<pre><code>map <key> command
</code></pre>
<p>the <code>cpp</code> compiling you mentioned should go like:</p>
<pre><code>autocmd FileType cpp nmap <buffer> <F5> :w<bar>!g++ -o %:r % && ./%:r<CR>
</code></pre>
<p>Add this command to your <code>vimrc</code> and will compile and run the current cpp file.<br><br>
<code>FileType cpp</code>- detects the <code>cpp</code> file directly, (<em>no need of manual regex</em>).<br>
<code>nmap</code>- used for mapping key while normal mode.<br>
<code>buffer</code>- for the current buffer (<em>in case of multiple splits</em>).<br>
<code><F5></code>- for mapping the 'F5' key.<br>
And the command that executes is: <code>:w | !g++ -o %:r % && ./%:r<CR></code><br></p>
<p>In the above command, <code>%</code> is the file name without extension, while <code>%:r</code> is the file name(<em>with extension</em>),<br> <code><CR></code> stands for the "Enter" button (<em>Carriage Return</em>)</p>

block multiple request from same user id to a web method c# <p>I have a web method upload Transaction (ASMX web service) that take the XML file, validate the file and store the file content in SQL server database. we noticed that a certain users can submit the same file twice at the same time. so we can have the same codes again in our database( we cannot use unique index on the database or do anything on database level, don't ask me why). I thought I can use the lock statement on the user id string but i don't know if this will solve the issue. or if I can use a cashed object for storing all user id requests and check if we have 2 requests from the same user Id we will execute the first one and block the second request with an error message
so if anyone have any idea please help</p>
| <p>Blocking on strings is bad. Blocking your webserver is bad. </p>
<p><code>AsyncLocker</code> is a handy class that I wrote to allow locking on any type that behaves nicely as a key in a dictionary. It also requires asynchronous awaiting before entering the critical section (as opposed to the normal blocking behaviour of locks):</p>
<pre><code>public class AsyncLocker<T>
{
private LazyDictionary<T, SemaphoreSlim> semaphoreDictionary =
new LazyDictionary<T, SemaphoreSlim>();
public async Task<IDisposable> LockAsync(T key)
{
var semaphore = semaphoreDictionary.GetOrAdd(key, () => new SemaphoreSlim(1,1));
await semaphore.WaitAsync();
return new ActionDisposable(() => semaphore.Release());
}
}
</code></pre>
<p>It depends on the following two helper classes:</p>
<p>LazyDictionary:</p>
<pre><code>public class LazyDictionary<TKey,TValue>
{
//here we use Lazy<TValue> as the value in the dictionary
//to guard against the fact the the initializer function
//in ConcurrentDictionary.AddOrGet *can*, under some conditions,
//run more than once per key, with the result of all but one of
//the runs being discarded.
//If this happens, only uninitialized
//Lazy values are discarded. Only the Lazy that actually
//made it into the dictionary is materialized by accessing
//its Value property.
private ConcurrentDictionary<TKey, Lazy<TValue>> dictionary =
new ConcurrentDictionary<TKey, Lazy<TValue>>();
public TValue GetOrAdd(TKey key, Func<TValue> valueGenerator)
{
var lazyValue = dictionary.GetOrAdd(key,
k => new Lazy<TValue>(valueGenerator));
return lazyValue.Value;
}
}
</code></pre>
<p>ActionDisposable:</p>
<pre><code>public sealed class ActionDisposable:IDisposable
{
//useful for making arbitrary IDisposable instances
//that perform an Action when Dispose is called
//(after a using block, for instance)
private Action action;
public ActionDisposable(Action action)
{
this.action = action;
}
public void Dispose()
{
var action = this.action;
if(action != null)
{
action();
}
}
}
</code></pre>
<p>Now, if you keep a static instance of this somewhere:</p>
<pre><code>static AsyncLocker<string> userLock = new AsyncLocker<string>();
</code></pre>
<p>you can use it in an <code>async</code> method, leveraging the delights of <code>LockAsync</code>'s <code>IDisposable</code> return type to write a <code>using</code> statement that neatly wraps the critical section:</p>
<pre><code>using(await userLock.LockAsync(userId))
{
//user with userId only allowed in this section
//one at a time.
}
</code></pre>
<p>If we need to wait before entering, it's done asynchronously, freeing up the thread to service other requests, instead of blocking until the wait is over and potentially messing up your server's performance under load.</p>
<p>Of course, when you need to scale to more than one webserver, this approach will no longer work, and you'll need to synchronize using a different means (probably via the DB).</p>

| <p>The problem is that Excel doesn't understand the columns. To fix this you need to send instructions to Excel explaining the csv file.</p>
<p>The instruction needs to be the first part of the file, before the data so you have to create an alias for the first field in the query that contains the Excel instructions along with the actual name you want</p>
<p>The instruction is âsep=,â, to ensure that excel will understand comma field separator.</p>
<pre><code>DECLARE @column1name varchar(50)
-- Create the column name with the instrucation in a variable
SET @Column1Name = '[sep=,' + CHAR(13) + CHAR(10) + 'Name]'
DECLARE @qry varchar(8000)

ios - SocketMobile SocketScan Carrier Name <p>I implemented <code>socket scan API</code> in iOS to scan and get the bar code and that seems to be working fine. I wanted to know if there is a way to find out the carrier name via the <code>socket scan API</code> ?</p>
| <p>ScanAPI only provides the data that is encoded in the barcode and the barcode type. For example, the 12 digits of a UPC-A barcode - which are often printed below the barcode too.</p>
<p>However, different carriers use different barcode types or format the encoded data differently. For example, UPS uses Aztec barcodes. USPS uses Code 128, which is quite common, but the barcode contains the tracking number which will start with a particular prefix depending on which service was used to send the letter/parcel.</p>
<p>You can probably detect the carrier using this information, but you'd need to figure out the pattern for each carrier yourself.</p>

Switch Derived class of a shared pointer to base class <p>I am currently trying to switch the type of a derived class stored in a shared pointer to base class.
The problem is that the Derived class inherit from the Base class and is also templated as follow:</p>
<p>Base class:</p>
<pre><code>#define PRINT(s) std::cout << s << std::endl
class Base {
public:
Base() : m_a(1) {}
virtual ~Base() = default;
virtual void print() { PRINT("BASE"); }
int m_a;
};
</code></pre>
<p>The derived class depend on an enumeration template:</p>
<pre><code>enum eType { e0, e1 };
template<eType et>
class Derived : public Base { };
template<>
class Derived<e0> : public Base {
public:
Derived() { this->m_a = e0; }
void print() { PRINT("Derived e0, m_a value: " << e0 ); }
};
template<>
class Derived<e1> : public Base {
public:
Derived() { this->m_a = e1; }
void print() { PRINT("Derived e1, m_a value: " << e1 ); }
};
</code></pre>
<p>My objective is to have a shared pointer to the Base class so it would be possible to switch from the 2 derived classes as follow:</p>
<pre><code>int main()
{
std::shared_ptr<Base> sp_00 = std::make_shared<Derived<e0>> ();
std::shared_ptr<Base> sp_01 = sp_00;
sp_01->print();
std::shared_ptr<Base> sp_10 = std::make_shared<Derived<e1>> ();
*sp_01 = *sp_10;
sp_01->print();
sp_10->print();
}
</code></pre>
<p>The only problem as on the line <code>*sp_01 = *sp_10;</code> I expect that the pointer to base class switch from the derived type <code>Derived<e0></code> to the derived type <code>Derived<e1></code>. However in my example I get a different result for the line <code>sp_01->print();</code> and the line <code>sp_10->print();</code> indicating that <code>sp_01</code> stays as a <code>Derived<e0></code> type.</p>
<p>I want to avoid <code>sp_01 = sp_10;</code> because it will change the pointer. In the above example, it would lead to <code>sp_00 != sp_01</code> and I want both <code>sp_00</code> and <code>sp_01</code> to share the same object.</p>
<p>I tried to replace the template derived class by a non template derived class as follow:</p>
<pre><code>class Derived_e0 : public Base {
public:
Derived() { this->m_a = e0; }
void print() { PRINT("Derived e0, m_a value: " << e0 ); }
};
class Derived_e1 : public Base {
public:
Derived() { this->m_a = e1; }
void print() { PRINT("Derived e1, m_a value: " << e1 ); }
};
</code></pre>
<p>and the following code give the same result as the one with template.</p>
<pre><code>int main()
{
std::shared_ptr<Base> sp_00 = std::make_shared<Derived_e0> ();
std::shared_ptr<Base> sp_01 = sp_00;
sp_01->print();
std::shared_ptr<Base> sp_10 = std::make_shared<Derived_e1> ();
*sp_01 = *sp_10;
sp_01->print();
sp_10->print();
}
</code></pre>
<p>So my question is, how to switch the derived object pointed by a shared pointer without changing the shared_ptr itself (which is used in other part of the program ?)</p>
<p>Thanks, if you need any more information, please let me know</p>
| <p>You cannot change the runtime type of <code>sp_01</code> without re-assigning it because you cannot assign <code>Derived<e1></code> to <code>Derived<e0></code> (think of what would happen if these do not have the same size - you have allocated enough size for a <code>Derived<e0></code>, not for a <code>Derived<e1></code>!).</p>
<p>In my opinion, your design (or what you are trying to do with it) is flawed somewhere. However, if you really want to keep a "link" between <code>sp_00</code> and <code>sp_01</code>, you probably need another "level" of pointer:</p>
<pre><code>int main() {
std::shared_ptr<Base> *psp_01;
std::shared_ptr<Base> sp_00 = std::make_shared<Derived<e0>> ();
psp_01 = &sp_00;
(*psp_01)->print();
std::shared_ptr<Base> sp_10 = std::make_shared<Derived<e1>> ();
psp_01 = &sp_10;
(*psp_01)->print();
sp_10->print();
}
</code></pre>
<p>But again, I would analyze my design twice before using this.</p>
