39,288,595 | Why not just use random_device? | <p>I am a bit confused about the c++11 random library.</p>
<p>What I understand: we need two separate concepts:</p>
<ul>
<li>random engine (which can be pseudo (need seed) or real)</li>
<li>distribution: it maps the numbers obtained from the engine to a specific interval, using a specific distribution.</li>
</ul>
<p>What I don't understand is why not just use this:</p>
<pre><code>std::random_device rd;
std::uniform_int_distribution<int> dist(1, 5);
// get random numbers with:
dist(rd);
</code></pre>
<p>As far as I can tell this works well.</p>
<p>Instead, this is what I found on most examples/sites/articles:</p>
<pre><code>std::random_device rd;
std::mt19937 e{rd()}; // or std::default_random_engine e{rd()};
std::uniform_int_distribution<int> dist{1, 5};
// get random numbers with:
dist(e);
</code></pre>
<p>I am not talking about special use, e.g. cryptography, just your basic getting started articles.</p>
<p>My suspicion is because <code>std::mt19937</code> (or <code>std::default_random_engine</code>) accepts a seed, it can be easier to debug by providing the same seed during a debug session.</p>
<p>Also, why not just:</p>
<pre><code>std::mt19937 e{std::random_device{}()};
</code></pre>

39,290,841 | Best approach to make a single page application | <p>I have seen many sites rendering json data in string format along with html in their page response:</p>
<p>Take an instance of this for example: view-source:<a href="https://www.netflix.com/in/" rel="nofollow noreferrer">https://www.netflix.com/in/</a></p>
<p><a href="https://i.stack.imgur.com/bDU7X.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/bDU7X.png" alt="enter image description here"></a></p>
<p>What is the benefit of rendering JSON in string format in page response itself.
One can render the page and can load data via ajax too when the page has rendered.</p>
<p>I am thinking to build a SPA website totally on Angular with no server controls on my page, all data coming via REST API.</p>
<p>What should be my approach on page rendering:</p>
<ol>
<li><p>Load the page (kind of blank) and then do a hit via ajax calls via Angular and fill the data into the page. This could have loading effect initially.</p></li>
<li><p>Load everything in html form page initially via server side code. No ajax request on load of the page this time. If a user wants some more data I can do an ajax request via Angular further.</p></li>
<li><p>Load JSON, the data for the page (in stringify format in script tags) + some html. The JSON data will be used to by Angular for templating and render the html there only. No ajax request is made this time too on page load since I rendered the data in json format along with page source. This is the case I posted earlier with Netflix url.</p></li>
</ol>
<p>What should be the best approach based on usability issue. I know Angular is great, but what is the best approach here to make a SPA.</p>

I know there's something wrong with static files but I don't understand much about it even when I already read <a href="https://docs.djangoproject.com/en/1.10/howto/static-files/#serving-static-files-in-development" rel="noreferrer">the docs</a>. I can do</p>
<p><code>python3 manage.py collectstatic</code></p>
<p>to create a static folder but I don't know where to put it and how to change the DIRS in settings.py. I really need some help to get rid of it.</p>

This however doesn't seem to be the case when I use a <code>TaskCompletionSource</code>.</p>
<p>My code looks something like this:</p>
<pre><code>Task<int> Foo() {
_tcs = new TaskCompletionSource<int>();
return _tcs.Task;
}
async void Bar() {
Console.WriteLine(Thread.Current.ManagedThreadId);
Console.WriteLine($"{Thread.Current.ManagedThreadId} - {await Foo()}");
}
</code></pre>
<p><code>Bar</code> gets called on a specific thread and the <code>TaskCompletionSource</code> stays unset for some time, meaning the returned tasks <code>IsComplete = false</code>. Then after some time, the same thread would proceed to call <code>_tcs.SetResult(x)</code>, which by my understanding should run the continuation on the threadpool.</p>
<p>But what I observed in my application is that the thread running the continuation is in fact still the same thread, as if the continuation was invoked synchronously right as <code>SetResult</code> is called.</p>
<p>I even tried setting a breakpoint on the <code>SetResult</code> and stepping over it (and having a breakpoint in the continuation), which in turn actually goes on to call the continuation synchronously.</p>

@Before
public void setup() {
reset(mockedServiceClient);
}
@Test
public void shouldBehaveACertainWay() {
// call component methods, assert results...
}
}
</code></pre>
<p>The problem with the above setup is that the component scan configured in MyApplication picks up Component1TestWithFakeCommunication.ContextConfiguration, so I get a mock ServiceClient even in Component1TestWithRealCommunication where I want the real ServiceClient implementation.</p>
<p>Although I could use @Autowired constructors and build up the components myself in both tests, there is a sufficient amount of stuff with complicated setup that I would rather have Spring TestContext set up for me (for example, Spring Data JPA repositories, components from libraries outside the app that pull beans from the Spring context, etc.). Nesting a Spring configuration inside the test that can locally override certain bean definitions within the Spring context feels like it should be a clean way to do this; the only downfall is that these nested configurations end up affecting all Spring TestContext tests that base their configuration on MyApplication (which component scans the app package).</p>
<p>How do I modify my setup so I still get a "mostly real" Spring context for my tests with just a few locally overridden beans in each test class?</p>

39,309,843 | How do you create multiple forms on the same page with redux-forms v6? | <p>I have a simple todo app in which my redux store contains an array of 'todos'. My 'Todo' component maps over every 'todo' in the store and renders a 'TodoForm' component that uses redux-forms v6.</p>
<p>As it is now, every 'todo' shares the same form name/key, so every time I input something in the 'title' Field, it changes the 'title' of every todo. I found a work around by using unique Field names, but I fear it's going to over complicate things as the app grows, and would prefer to use unique Form names so every field can have the same name without interfering with the other forms </p>
<p>(TodoForm1, TodoForm2, TodoForm3 can all have a unique 'title' Field instead of TodoForm containing 'title1', 'title2', 'title3' Fields).</p>
<p>I tried accessing the TodoForm's props so I could set each form's key as the component's unique id, but it doesn't seem like the component receives props that early. </p>
<p>I also tried making an immediately invoked function where it spits out a random number, and using that number as the form's name, but that also didn't work.</p>

39,310,147 | Upload a base64 image with Firebase Storage | <p>I'm making this app where users can have a profile picture (but only one picture each). I got everything set up, but when the pictures are 2mb+, it takes some time to load and actually I just need the pictures to be 50kb or so (only small display of pictures, max 40 pixels). I made some code to put the images directly into the realtime database (convert to canvas and make them a 7kb base64 string). However, this is not really clean and it's better to use Firebase Storage. </p>
<p>Since the new update 3.3.0 you can upload Base64 formatted strings to Storage, using the putString() method. However, when I upload my canvas image (which starts with "data:image/jpeg;base64,"), I get the error:</p>

# Consider dividing a string into two halves.
# If the length is even, the front and back halves are the same length.
# If the length is odd, we'll say that the extra char goes in the front half.

39,314,833 | Google API Client "refresh token must be passed in or set as part of setAccessToken" | <p>I am currently facing a very strange problem, indeed I've been following this very same guide (<a href="https://developers.google.com/google-apps/calendar/quickstart/php" rel="noreferrer">https://developers.google.com/google-apps/calendar/quickstart/php</a>) from Google API documentation. I tried it twice, at the first time it work like a charm but after the access token had expire the script provided straight by Google API Doc was unable to refresh it.</p>
<p>TL;DR</p>
<p>Here is the error message:</p>
<pre><code>sam@ssh:~$ php www/path/to/app/public/quickstart.php
Fatal error: Uncaught exception 'LogicException' with message 'refresh token must be passed in or set as part of setAccessToken' in /home/pueblo/www/path/to/app/vendor/google/apiclient/src/Google/Client.php:258

#2 {main}
thrown in /home/pueblo/www/path/to/app/vendor/google/apiclient/src/Google/Client.php on line 258
</code></pre>
<p>Here is the part of the php script from google I've modified:</p>
<pre><code>require_once __DIR__ . '/../vendor/autoload.php';
// I don't want the creds to be in my home folder, I prefer them in the app's root
define('APPLICATION_NAME', 'LRS API Calendar');
define('CREDENTIALS_PATH', __DIR__ . '/../.credentials/calendar-php-quickstart.json');
define('CLIENT_SECRET_PATH', __DIR__ . '/../client_secret.json');
</code></pre>
<p>I also modified the <code>expandHomeDirectory</code> so I could "disable" it without modifying too much code:</p>
<pre><code>function expandHomeDirectory($path) {
$homeDirectory = getenv('HOME');
if (empty($homeDirectory)) {
$homeDirectory = getenv('HOMEDRIVE') . getenv('HOMEPATH');
}
return $path;
// return str_replace('~', realpath($homeDirectory), $path);
}
</code></pre>
<p>So to check if I was wrong or if Google was, I did an experiment: yesterday night I launch the quickstart script from ssh to check if it was working, and indeed it was, so I decided to check this morning if it still working just as it was before I slept and it wasn't so I think there's something wrong with Google's <code>quickstart.php</code>.</p>
<p>I hope someone could help me, I already checked all the other posts about the subject but they are all outdated.</p>

<blockquote>
<p>Apps Script is based on JavaScript 1.6, plus a few features from 1.7 and 1.8. Many basic JavaScript features are thus available in addition to the built-in and advanced Google services: you can use common objects like Array, Date, RegExp, and so forth, as well as the Math and Object global objects. However, because Apps Script code runs on Google's servers (not client-side, except for HTML-service pages), browser-based features like DOM manipulation or the Window API are not available.</p>

39,317,887 | How to implement a method of a base class for every possible combination of its derived types | <p>I have the following Shape interface which is implemented by multiple other classes such as Rectangle, Circle, Triangle ...</p>
<pre><code>interface IShape{
bool IsColliding(IShape other);
}
</code></pre>
<p>The method IsColliding is supposed to check whether a Shape is colliding with another or not, regardless of their concrete type.
However, each couple of shape (Rectangle/Rectangle, Rectangle/Circle, Circle/Triangle etc...) have its own implementation for this collision check.</p>
<p>I'm trying to find a good design solution for this problem.</p>
<p>The naive method would be to switch over the type of the "other" shape to call the correct implementation :</p>
<pre><code>class Rectangle : IShape{
bool IsColliding(IShape other){
if(other is Rectangle){
return CollisionHandler.CheckRectangleVsRectangle(this,(Rectangle)other);
}else if(other is Circle){
return CollisionHandler.CheckRectangleVsCircle(this,(Circle)other);
} else
// etc ...
}
}
</code></pre>
<p>But adding a new shape would mean modifying the method in every derived class to add the new case.</p>
<p>I also thought of calling a unique static method like this one :</p>
<pre><code>static bool IsColliding(IShape shapeA, IShape shapeB);
</code></pre>
<p>But even if it centralizes everything, it doubles the number of type-test to perform and I'd still have to add a new case in each first-level "if".</p>
<pre><code>if(shapeA is Rectangle){
if(shapeB is Rectangle){
// Rectangle VS Rectangle
}else if(shapeB is Circle){
// Rectangle VS Circle
}else{
// etc ...
}
}else if(shapeA is Circle){
if(shapeB is Rectangle){
// Rectangle VS Circle
}else{
// etc ...
}
} // etc ...

39,318,059 | Calculate business days, Insert Keys and Diagrams | Hi everybody i'm working on a problem in C++ Builder, i have to create a task management software for a company, but i have too much trouble with some concepts. So my 1st problem is a simple one but i don't see the error:
I have on my form a TrStringGrid which is a modified TStringGrid and i want that each time the user clicks on insert on the keyboard that a row is filled automatically. The app starts with a tstringgrid with 2 rows, one is fixed and can't be modified and the second one is empty.
That's what it look like:
[![Grid][1]][1]
[1]: http://i.stack.imgur.com/K4cSl.png
So what i want to do is that the first time the user press the insert key the row n°2 is filled (the row that is not grey). The second and subsequent times the user press the insert key a row is added and filled automatically. I can't get it work and i don't know if i'm doing it the good way or not.
//method called each time a key is pressed
void __fastcall TForm1::rStringGridEd1KeyDown(TObject *Sender, WORD &Key, TShiftState Shift)
{
int counter = 1;
switch(Key)
{
case VK_INSERT: //VK_INSERT for the insert button
if(counter < 2)
{
for (int i = 0;i< rStringGridEd1->RowCount; i++) {
rStringGridEd1->Cells[0][i] = "a";
rStringGridEd1->Cells[1][i] = "b";
rStringGridEd1->Cells[2][i] = "c";
rStringGridEd1->Cells[3][i] = "d";
rStringGridEd1->Cells[4][i] = "e";
counter++;
}
}
if(counter >= 2){
for (int i = 0;i< rStringGridEd1->RowCount; i++) {
rStringGridEd1->RowCount++; // this is used to add a row
rStringGridEd1->Cells[0][i] = "a";
rStringGridEd1->Cells[1][i] = "b";
rStringGridEd1->Cells[2][i] = "c";
rStringGridEd1->Cells[3][i] = "d";
rStringGridEd1->Cells[4][i] = "e";
counter++;
}
}
}
}
My next problem is how to add only business days to a specific date that the user entered. I can't get it work correctly.
//Method I used to calculate date is the start date and the variable days are the days to add to date to get the new date
TDate __fastcall TForm1 ::calulatenewdate( TDate date, int days)
{
TDate tmp; //tmp is used inside this method as date
tmp = date;
// j is used for to get the day of the week (Monday, Tuesday, Wesdnesday, etc..)
int j;
if (days == 1){
return date;}
if (days == 2){
tmp= +1;
j = DayOfWeek(tmp);
// the day of the week is given in numbers from 1 to 7 ( 1 = Sunday, 2 = Monday, 3 = Wesdnesday,etc…)
if (j == 7) { //So if j =7 which is Saturday add two days to get to monday
tmp = tmp+2;
return tmp;
}else{
return tmp;
} }
if(days > 2){ // if the user enter a day greater than 2
for(int i =0; i < days;i++)
{
tmp=tmp+1;
j = DayOfWeek(tmp);
if (j == 7) {
tmp =+2;
}
}
return tmp;
}
and my third and last problem is that i want to draw horizontal diagrams,are there any good ones out there? Can anyone recommend me one? I'm really sorry for my bad english, it's not my mothertongue.

Moderators, feel free to move this to the proper location.</p>
<p>When compiling my code using the latest XCode 8 beta 6 (iOS 10 SDK), I get an exception "Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIDeviceRGBColor countByEnumeratingWithState:objects:count:]: unrecognized selector sent to instance 0x600000071340'"</p>
<p>This happens during the call:</p>
<pre><code> auto viewController = [[[UIViewController alloc] initWithNibName:@"ViewController" bundle:nil] autorelease];
</code></pre>
<p>I have isolated the problem by whittling down my project to the bare minimum that will compile and still exhibit the problem. You can download it here:</p>
<p><a href="https://www.dropbox.com/s/b7jggae97889xka/Bugtest.zip?dl=0" rel="noreferrer">Example project</a></p>
<p>Note that I took out lots of code, nearly all classes are gone, which results in a lot of warnings (not errors) for nonexistent classes referenced from the xib. But that doesn't matter, the code still compiles and runs just fine with the iOS 9 SDK. After compiling with the iOS 10 sdk, however, it crashes both in the simulator and on devices running iOS 9.</p>
<p>You can work around the problem by changing "#if 0" into "#if 1" in the file "HackForUnrecognizedSelectorInIOS10.m". This adds a category defining the missing selectors for UIColor. But obviously you can't add that to shipping code, it's just a temporary stopgap measure to continue developing.</p>
<p>I filed a bug report (28153870). But if anyone has any more information on how to avoid this problem without ugly hacks, any information is welcome.</p>

where det123.WorkTypeId == 2
select new
{
fixednum = det123.number,
}).ToList();
dataresource contains values (A,B,C)
datafixed contains values (D,E,F,G,H)
Result expected is
Resultlist =
A D
B E
C F
null G
null H
Tried using .ZIP() but unable to handle the listt with unequal size

39,319,070 | is "from flask import request" identical to "import requests"? | <p>In other words, is the flask request class identical to the requests library?</p>

<p>but cannot tell for sure. I see code examples where people seem to use them interchangeably.</p>

39,320,445 | " textarea " multilines PHP/ HTML | I am using php and html codes in same file for contact form.
When I write multilines in html form (textarea):
(name="TBody" cols="100" rows="10" class="largertextarea" required="required" placeholder="Leave A Message Here"),
the php received the information and put all of them in same line :
$body = $_POST["TBody"];
$msgbody = "- Message is about:" . "<br>" . $body;
For example :
Hi,
Hope all are fine.
Bye.
What I receive in email is like this :
Hi, Hope all are fine. Bye.
So, how can I put them in multilines ?
Thanks in advance for your help. | <php><html> | 2016-09-04 18:58:07 | LQ_EDIT |

<p>I'm aware that there are ways to do this like this one:</p>

<p>But does it have a much simpler and typo less way?</p>
