Python3: If ... else .... ignored when checking Json attribute existance : I have the following python3 code to check if a attribute is in a Json (or has a value different than null)
def has_attribute(data, attribute):
return (attribute in data) and (data[attribute] is not None)
This is the function which checks that the attribute is in the json and has a value different than null.
if has_attribute(json_request,"offer_id"):
print("IT IS")
else:
print("NO")
The thing is that when I pass a Json it doesn't print nothing!
Why?

lua odd table behaviour : In my code, I set a variable to the contents of a table, like so:
colorTable = {{255, 255, 255}}
color = colorTable[1]
My problem is when I edit the value of `color` it changes the original value in `colorTable`
so in the beginning, `colorTable[1][1]` equals `255`, but after I run this:
color[1] = color[1] - 10
`colorTable[1][1]` equals `245`.
Any help is appreciated.

Is there any way to get the live chat replay log/history for YouTube streaming video? : <p>Recently I'm doing research for online chat message patterns. I chose YouTube and Twitch.tv for chat message sources.</p>
<p>So I found chat loggers for real-time livestream, but I also need log/history for already broadcasted livestream which allows live chat replay. (like <a href="https://www.youtube.com/watch?v=1JfohG5a8y8" rel="noreferrer">https://www.youtube.com/watch?v=1JfohG5a8y8</a> )</p>
<p>There are tool for Twitch.tv (<a href="https://github.com/jdpurcell/RechatTool" rel="noreferrer">RechatTool from jdpurcell</a>), but I couldn't find any similar one of them for YouTube.</p>
<p>So I checked <a href="https://developers.google.com/youtube/v3/live/docs/liveChatMessages/list" rel="noreferrer"> YouTube API for livestream messages</a>, but I couldn't find any instructions or tips for live chat replay. Is there any possible solutions for this?</p>

How to make volumes permanent with Docker Compose v2 : <p><em>I realize other people have had similar questions but this uses v2 compose file format and I didn't find anything for that.</em></p>
<p>I want to make a very simple test app to play around with MemSQL but I can't get volumes to not get deleted after <code>docker-compose down</code>. If I've understood Docker Docs right, volumes shouldn't be deleted without explicitly telling it to. Everything seems to work with <code>docker-compose up</code> but after going down and then up again all data gets deleted from the database.</p>
<p>As recommended as a good practice, I'm using separate memsqldata service as a separate data layer.</p>
<p>Here's my docker-compose.yml:</p>
<pre><code>version: '2'
services:
app:
build: .
links:
- memsql
memsql:
image: memsql/quickstart
volumes_from:
- memsqldata
ports:

- "9000:9000"
memsqldata:

volumes:

Install udunits2 package for R3.3 : <p>I just wasted the whole day trying to figure out how to install the udunits2 package to be able to install the units package to be able to install the ggforce and ggraph packages.</p>

<p>So, umm, it's looking for the udunits2.h and libudunits2.a files....
So, I downloaded udunits2 from CRAN, unpacked it and put it in my R library.
Then, if I put library(udunits2, lib.loc = "my library dir") I get an error saying it's not installed. So, when I install.package('udunits2', repo = NULL, libconfig.args = '--with-udunits2-lib=/home/fjay/R/x86_64-pc-linux-gnu-library/3.3') or install.packages('units',....) or install.packages('ggforce',...) it is still looking for these files...and, after inspection of the udunits2 package these files are not in any of the udunits2 folders.</p>
<p>If anyone knows how to install this udunits2 packages please help me! </p>

Puppeteer check through website content/elements : <p>I need to check through the elements of the website for my code, but I can't understand how to do it with puppeteer on Node.JS
<br>Here's the code I tried:</p>
<pre><code>if(page.content('input[data-kwimpalaid="1580983806648-1"]'))
found = true
if(found = true)
console.log("I found it")
if(found = false)
console.log("I didn't found it")
</code></pre>
<p>So what I need basically, I have a website with element ID's ending in 1 to 20, and it can be random, and consecutive. For example it may start at 1, then has 6 ids (1,2,3,4,5,6) or it can start at 5 (5,6,7,8,9,10). I want to check for every ID, and if it exists then change the value of ''found'' to <code>true</code>. If the page doesn't have id 1, try id 2, id 3, id 4, etc.. until it finds an input with that ID/CLASS that exists on that website.</p>
<p><br><br>Shortly, I need to check if the selector element I use exists on the website or not (content).</p>

Jupyter magic to handle notebook exceptions : <p>I have a few long-running experiments in my Jupyter Notebooks. Because I don't know when they will finish, I add an email function to the last cell of the notebook, so I automatically get an email, when the notebook is done.</p>
<p>But when there is a random exception in one of the cells, the whole notebook stops executing and I never get any email. <strong>So I'm wondering if there is some magic function that could execute a function in case of an exception / kernel stop.</strong></p>
<p>Like</p>
<pre><code>def handle_exception(stacktrace):
send_mail_to_myself(stacktrace)
%%in_case_of_notebook_exception handle_exception # <--- this is what I'm looking for
</code></pre>
<p>The other option would be to encapsulate every cell in try-catch, right? But that's soooo tedious.</p>
<p>Thanks in advance for any suggestions.</p>

Qt: Program is crashing when deleting central widget of QMainWindow in destructor : <p>I am learning Qt. Currently I stuck at layout stuff for <code>QMainWindow</code>. As suggested in some of examples available on internet i used <code>QWidget</code> to be used in <code>setCentralWidget(QWidget*)</code> method of QMainWindow. But as part of clean up when i am deleting central <code>QWidget</code> the program is crashing.</p>
<p>here is the code for .h</p>
<pre><code>class MyMainWindow : public QMainWindow
{
Q_OBJECT
public:
explicit MyMainWindow(QWidget *parent = 0);
~MyMainWindow();
private:
QVBoxLayout m_p1_level_vbox;
QHBoxLayout m_p2_level_vbox;
QHBoxLayout m_p2_level_hbox;
QWidget* m_central_widget;
QPushButton* m_increase_pressure;
QPushButton* m_decrease_pressure;
};
</code></pre>
<p>for .cpp</p>
<pre><code>MyMainWindow::MyMainWindow(QWidget *parent)
: QMainWindow(parent)
, m_central_widget(new QWidget(this))
, m_increase_pressure(new QPushButton("+", this))
, m_decrease_pressure(new QPushButton("-", this))
{
m_p2_level_hbox.addWidget(m_increase_pressure);
m_p2_level_hbox.addWidget(m_decrease_pressure);
m_p1_level_vbox.addLayout(&m_p2_level_hbox);
m_central_widget->setLayout(&m_p1_level_vbox);
setCentralWidget(m_central_widget);
}
MyMainWindow::~MyMainWindow()
{
delete m_central_widget; // commenting this line doesn't crash the program
delete m_increase_pressure;
delete m_decrease_pressure;
}
</code></pre>
<p>main.cpp</p>
<pre><code>int main(int argc, char *argv[])
{
QApplication a(argc, argv);
MyMainWindow w;
w.show();
return a.exec();
}
</code></pre>
<p>In destructor if i don't delete <code>m_central_widget</code> then it works.</p>
<p>What i am doing wrong here?</p>

How to fix my non-starting little game app? : <p>I have to do a little game for my school, and I'm stuck in my program. When I launch the app it's working fine, but when I want to start a new game by the menubar, it says that the game is starting, but it isn't.

Windows: Auto start PM2 and node apps : <p>At a Windows AWS server i have a NODE app and
i'm using PM2 to launch the app</p>
<p>I have tried the NPMs: "pm2-windows-startup" and "pm2-windows-service"</p>
<p>But after i restart my AWS instance and run</p>
<pre><code>PM2 ls
</code></pre>
<p>No node app shows up in the list...</p>
<p><strong>I followed the instructions ...</strong></p>
<ol>
<li>Installed the NPM (So PM2 auto start after reboot)</li>
<li>PM2 start myApp.js --name mySuperApp</li>
<li>PM2 save</li>
<li>Reboot</li>
<li>PM2 ls --> no running node apps? :-(</li>
</ol>
<p><strong>The PM2 logs dont contain any thing...</strong></p>
<p>I have not added any ENV variables explicit (when i tried PM2 could not start any more - so i created a fresh AWS windows instance and installed every thing from scratch again...)</p>
<p>PM2 is located the default place (i have not changed any paths)</p>

ASP.net core MVC catch all route serve static file : <p>Is there a way to make a catch all route serve a static file?</p>
<p>Looking at this <a href="http://blog.nbellocam.me/2016/03/21/routing-angular-2-asp-net-core/" rel="noreferrer">http://blog.nbellocam.me/2016/03/21/routing-angular-2-asp-net-core/</a></p>
<p>I basically want something like this:</p>
<pre><code> app.UseMvc(routes =>
{
routes.MapRoute("default", "{controller}/{action=Index}");
routes.MapRoute("spa", "{*url}"); // This should serve SPA index.html
});
</code></pre>
<p>So any route that doesn't match an MVC controller will serve up <code>wwwroot/index.html</code></p>

Enumerate Dictionary.Values vs Dictionary itself : <p>I was exploring the sources of ASP.NET core on GitHub to see what kind of tricks the ASP.NET team used to speed up the framework. I saw something that intrigued me. In the source code of the <a href="https://github.com/aspnet/DependencyInjection/blob/dev/src/Microsoft.Extensions.DependencyInjection/ServiceProvider.cs" rel="noreferrer">ServiceProvider</a>, in the Dispose implementation, they enumerate a dictionary, and they put a comment to indicate a performance trick :</p>
<pre><code>private readonly Dictionary<IService, object> _resolvedServices = new Dictionary<IService, object>();
// Code removed for brevity
public void Dispose()
{
// Code removed for brevity
// PERF: We've enumerating the dictionary so that we don't allocate to enumerate.
// .Values allocates a KeyCollection on the heap, enumerating the dictionary allocates
// a struct enumerator
foreach (var entry in _resolvedServices)
{
(entry.Value as IDisposable)?.Dispose();
}
_resolvedServices.Clear();
}
</code></pre>
<p>What is the difference if the dictionary is enumerated like that ?</p>
<p></p>
<pre><code>foreach (var entry in _resolvedServices.Values)
{
(entry as IDisposable)?.Dispose();
}
</code></pre>
<p>It has a performance impact ? Or it's because allocate a <a href="https://msdn.microsoft.com/en-us/library/x8bctb9c(v=vs.110).aspx" rel="noreferrer">ValueCollection</a> will consume more memory ?</p>

PHP includ another file, loop over array and run function for each record : PHP loop over array and run function for each record
I would like to access the values of an array in another php file ... loop over it and run a function over each record. I can't seem to access the values though ... I'm getting an internal error. How to properly do this? That's my setup:
contacts.php
<?php
$contacts_de = array(
'name01' => array(
'firstName' => 'FirstName01',
'lastName' => 'LastName01',
'gender' => 'm',
'language' => 'de',
'email' => 'email01'
),
'name02' => array(
'firstName' => 'FirstName02',
'lastName' => 'LastName02',
'gender' => 'f',
'language' => 'de',
'email' => 'email02'
)
);
mail.php
<?php
include('contacts.php');
function renderContacts($arr) {
global $lang,$contacts_de;
$d = '';
foreach($arr as $i) {
if ($i['gender'] == 'm') {
.$d = 'Mr. '.$i['firstName'].' '.$i['lastName']
} else if ($i['gender'] == 'm') {
.$d = 'Ms. '.$i['firstName'].' '.$i['lastName']
}
}
echo $d;
}
renderContacts();
default.js
$('#sendbtn').on('click', function() {
$.ajax({
type: "POST",url: '/mail.php',
success: function(response,textStatus,jqXHR) {
console.log(response);
},
error: function (jqXHR, status, err) {
console.log(err);
}
});
});
Desired Console.log
Mr. FirstName01 LastName01
Ms. FirstName02 LastName02

Compare Two String With Optional Characters : consider we have a function (in Django || python) which compares two strings, one is the correct answer and another is student answered string.
correct = '(an) apple (device)'
student_answerd = 'apple device'
I want to check student_answered with the correct string but parentheses are optional it means all the below student_answered is correct:
case 1: an apple device
case 2: an apple
case 3: apple device
notice: we don't have the same correct format for all questions it means the location of parentheses is different for example maybe we just have one parentheses or more.

Get content of HTML element without WebBrowser? : <p>How can you extract the content of an element from a webpage such as the possession of Paris Saint-Germain from <a href="https://www.whoscored.com/Statistics" rel="nofollow noreferrer">https://www.whoscored.com/Statistics</a> without the use of WebBrowser?</p>
<p>This data is updated frequently and is not accessible from the source code that can be received by an HTTP request. If possible, I would access such data asynchronously to make the scraping go faster. To my understanding, one WebBrowser object cannot load/open multiple pages at once. In that case, a separate WebBrowser object would then have to be created for each asynchronous process which would probably be a big overhead.</p>

How can I resolve a domain name to an IP address? : I need to resolve any given domain in PHP to its corresponding IP address. [`gethostbyname`][1] appears to perform a reverse DNS (rDNS) and isn't useful for obtaining the IP address of a domestic connection (that doesn't have direct rDNS).
I have the following, which of course doesn't work:
<?php
if (ISSET($_POST["domain"])) {
require_once("/protected/db.php");
echo gethostbyname($_POST["domain"]);
}
echo "Error";
?>
How can I do this?

nested scrollview + recyclerview, strange autoscroll behaviour : <p>In a view pager I have several fragments, one of them uses a nested scrollview with a header and a recyclerview : </p>

<p>The tag "header" represents a complex layout that I didn't want to post here as it stretches out the code a lot.</p>
<p>when I switch between the tabs, it scrolls strait to the recycler view. The header is hidden, I have to scroll up to see it.</p>
<p>Any ideas on what causes that ? I don't wanna use a type in my adapter if I can avoid it.</p>

Exception Handling in c# - try catch finally : <p>I am bit confused regarding the finally block. I know that finally block gets executed no matter if there is an exception or not.</p>
<p>I have got 2 scenarios :-</p>
<p>1) If there is an exception in try block and I have not written any catch block for this try block, but I have a finally block, then will the finally block gets executed? Does finally block executed if the exception is unhandled?</p>
<p>Below is an example code :- </p>
<pre><code>static void Main(string[] args)
{
int x = 0;
try
{
int divide = 12 / x;
}
//catch (Exception ex)
//{
// int divide = 12 / x;
// Console.WriteLine(ex.Message);
//}
finally
{
Console.WriteLine("I am finally block");
}
Console.ReadLine();
}
</code></pre>
<p>2) Will the finally block get executed if there is an exception in catch block?
Below is the sample code :-</p>
<pre><code>static void Main(string[] args)
{
int x = 0;
try
{
int divide = 12 / x;
}
catch (Exception ex)
{
int divide = 12 / x; // this will throw exception in catch block
Console.WriteLine(ex.Message);
}
finally
{
Console.WriteLine("I am finally block");
}
Console.ReadLine();
}
</code></pre>
<p>I have tried these codes and I don't see the finally block getting executed.
Please explain me why the finally block is not executed.</p>

ERR_TOO_MANY_REDIRECTS wordpress Google chrome : I'm having a weird issue, wordpress homepage has a 302 error (redirection loop) on Google Chrome only, however if I access my admin panel first and then go back to homepage, it works...
I have WPML installed and Yoast SEO.
Installation is in a subfolder.
Would somebody have an idea of what is going on?
Here is the link: [www.scrybs.com][1]

Javaskript : Simple substraction returns NaN : I have a problem,
my collision detection function sometimes sets entity position to NaN.
When I open console (on chrome) position of entity and collision are valid numbers but substracting them from each other sometimes returns NaN.
updateCollision = function(entity,rect) {
var a = entity.x - rect.x; // a = NaN , entity.x = 3117.2646499953607 , rect.x = 3296.976967651385
var b = entity.y - rect.y; // b = NaN , entity.y = 3024.105915848102 , rect.y = 3144.4270586199345
if( isNaN(a) ) // isNaN(a) = true
{
console.log("not again >:("); // but console doesn't log
}
//the code continues but its not important
[(screenshot of console)][1]

How to trigger VSTS build and release when pushing tags? : <p>I have rather simple scenarion, one master branch then when I want to do a production release I want to tag a commit with eg. vX.X.X.</p>
<p>The CI/CD pipeline looks like this</p>
<p>Build -> Staging Environment -> Production Environment</p>
<ol>
<li>Every commit to master is sent to staging environment</li>
<li>When I add a vX.X.X tag to a commit I want the staging and production environment to trigger.</li>
</ol>
<p>I have found this link <a href="https://visualstudio.uservoice.com/forums/330519-visual-studio-team-services/suggestions/13326927-trigger-build-when-pushing-tag-to-git?page=1&per_page=20" rel="noreferrer">Trigger build when pushing tag to git</a>. I just can't figure it out how to make it work. It simply does not work for me.</p>
<p>Is it possible and how do I configure the VSTS to start a build when a tag is added to a commit? </p>

Is there any way to increase visibility with a using declaration? : <p>The following code doesn't compile:</p>
<pre><code>class C
{
private:
int m_x;
protected:
C(int t_x) : m_x(t_x) { }
};
class D : public C
{
public:
using C::C;
};
int main(int argc, char **argv)
{
D o(0);
}
</code></pre>
<p>The compiler's objection is that the constructor for C is declared <code>protected</code>, meaning that I can't access it from <code>main</code>. In other words, it seems like the <code>using</code> declaration drags the original visibility of the identifier with it, despite the fact that it lives in the <code>public</code> block.</p>
<p>Two questions:</p>
<ol>
<li>Why does this happen? (Both in terms of the rules for how this works, and the rationale for making those rules).</li>
<li>Is there any way I can get around this without explicitly writing a constructor for <code>D</code>?</li>
</ol>

Guava's Immutable filtering via Java 8 parallel stream : Need help in filtering Guava's ImmutableTable via parallel stream and collector
Immutable<fieldA1,fieldB1,Boolean> validEntry;
Immutable<ObjectA, String, ObjectB> tofilter;
ObjectA{
String fieldA1
String fieldA2
}
ObjectB{
String fieldB1
String fieldB2
}
Usecase : iterate over toFilter and remove elements which are not present or entry value is false in validEntry table.
Map<ObjectA, Map<String, ObjectB>> rowMap = toFIlter.rowMap();
//This will result into stream of stream
for(loop over rowMap){
for(Loop over rowMap entry){
if(present in validEntry){
//add entry to new table
}
}
}
build new table
How can i utilize flat map to convert this stream of streams.

How to run python function after completed other function : my purpose is, when I run "list.py" first step, script will read a target_list.txt and it will create a domain list as "http://testsites.com".
if this process when completed, it means finish the target_list, other function must run. Here's code
example:
import Queue
#!/usr/bin/python
import Queue
targetsite="target_list.txt"
def domaincreate(targetsitelist):
for i in targetsite.readlines():
i = i.strip()
Url="http://"+i
DomainList=open("LiveSite.txt","rb")
DomainList.write(Url)
DomainList.close()
def SiteBrowser():
TargetSite="LiveSite.txt"
Tar=open(TargetSite,"rb")
for Links in Tar.readlines():
Links=Links.strip()
UrlSites="http://www."+Links
browser = webdriver.Firefox()
browser.get(UrlSites)
browser.save_screenshot(Links+".png")
browser.quit()
domaincreate(targetsite)
SiteBrowser()

Custom angular directive and custom html tag not working : I am creating an application in Django and Angular. I have created one custom Angular Directive as below:
(function () {
'use strict';
angular.module('scrumboard.demo')
.directive('scrumboardCard', CardDirective);
function CardDirective() {
return {
templateurl: '/static/scrumboard/card.html'
restrict: 'E'
};
}
})();
And called it through custom HTML tag as below:
<ul>
<p ng-repeat="card in list.cards">
<scrumboard-card></scrumboard-card>
</li>
</ul>
However, I can see that the directive is not being called at all. I even tried putting garbage code in the angular directive so as to generate error, but the page just loads without calling that angular directive.
