40,046,598 | MSAL or ADAL library for use with Azure AD B2C and Xamarin | <p>As of October 2016, is it still the case that the Microsoft Authentication Library (MSAL - NuGet package: <em>Microsoft.Identity.Client</em>) is the correct/only library to use with Xamarin (iOS/Android) and the Azure AD B2C service? This library (MSAL) is only available as an alpha and does not appear to be in a state of being actively maintained or developed (since April).</p>
<p>There are indications that the Active Directory Authentication Library (ADAL - NuGet package: <em>Microsoft.IdentityModel.Clients.ActiveDirectory</em>) is intended as Microsoft's "one-Azure-authentication-library-to-rule-them-all", and it supports Xamarin; it is also being actively maintained and is not in "alpha" or "beta" status.</p>
<p>Understanding that Microsoft has in the past pointed Azure AD B2C developers towards using the MSAL library, is it possible to authenticate Azure AD B2C users in a Xamarin app using the ADAL library instead? Are there blogs or sample code that someone could point me to, that would demonstrate how to do this?</p>

40,063,649 | Swift: create object from primitive value | <p>I'm not entirely sure that what I want to do is possible to implement currently, however I hope that it is.<br>
Basically, I would like to have some mechanism for a bit shorter object creation for primitive. Let me explain. Consider we have some kind of wrapper around Int:</p>
<pre><code>class Wrapper {
var value: Int = 0
init(value: Int) {
self.value = value
}
}
</code></pre>
<p>And then instead of creating object with init, i.e:</p>
<pre><code>let wrapper = Wrapper(value: -1)
</code></pre>
<p>I would like to do something like this:</p>
<pre><code>let wrapper: Wrapper = -1
</code></pre>
<p>Or:</p>
<pre><code>var array = [Wrapper]()
array.append(-1)
</code></pre>
<p>It would short declarations quite heavily, especially in case with arrays.<br>
Interesting note: I've tested code above with CGFloat i.e:</p>
<pre><code>let val: CGFloat = 0.0
var array = [CGFloat]()
array.append(0.0)
</code></pre>
<p>and all seems to be working fine. However I'm not entirely sure that there is way in language that allow to create such behaviour for custom object and it's why I'm asking about it basically. I've reviewed sources of CGFloat, but didn't saw anything that seems to be related to functionality that i want to achieve (beside NativeType alias may be, but I didn't understand how it would work).</p>

The code is like such:

global $post;
$args = array( 'post_id' => $post->ID );
$comment = get_comments( $args );

It basically stats that if there is less than 3 comments then show the comment form but if there is more than 3 and is the post author then show a button. The button shows but only if there are more than 3 comments. It doesn't check if it is only the post author or not, like i want it to. | <php><if-statement><statements> | 2016-10-15 21:37:28 | LQ_EDIT |

40,064,779 | Google Maps GMSMapView on custom UIView | <p>I want to display google maps on a view that's then added to <code>self.view</code>, rather than drawing the map directly on <code>self.view</code>.

<pre><code>let mapView = GMSMapView.map(withFrame: CGRect.zero, camera: GMSCameraPosition.camera(withLatitude: 51.050657, longitude: 10.649514, zoom: 5.5))

<pre><code>self.view.addSubview(mapView)
</code></pre>
<p>...and inserting it:</p>
<pre><code>self.view.insertSubview(mapView, at: 0)
</code></pre>
<p>Note that I'm using Auto Layout if that changes anything.</p>

40,073,651 | regex: check if two phone numbers differ at most by 1 number | <p>I have a dataset of phone numbers that I want to check against each other. Basically the regex should throw a match if two phone numbers are at most 1 digit apart. For example, we have the following phone numbers:</p>
<ul>
<li>+31612345678</li>
<li>+31612245678</li>
</ul>
<p>These numbers are the same apart from position number 7 (first number has a 3 while the second number has a 2). As these phone number differ by 1 digit, the regex should throw a match. It stands to reason that the regex should also throw a match if the phone numbers are exactly the same. In the following case (see below), the regex should however not throw at match as the phone numbers differ by more than 1 digit:</p>
<ul>
<li>+31612345678</li>
<li>+31611145678</li>
</ul>
<p>Does anyone have a good regex in mind? I am writing the regex using the re module in python. </p>

// We received a connection and need to pass it to the appropriate
// worker. Get the worker for this connection's source IP and pass
// it the connection.
var worker = workers[worker_index(connection.remoteAddress, num_processes)];

<p>What about special conventions related to pattern matching, for comprehensions, try-catch blocks and other language constructs?</p>

<p>Now I want to get the height of the whole table view. I tried getting it through <code>tableView.contentSize.height</code> but that only returns the estimated row height, and not the actual dynamic height of the table view.</p>

40,080,473 | Using JSON.stringify in conjunction with TypeScript getter/setter | <p>I am using getter/setter accessors in TypeScript. As it is not possible to have the same name for a variable and method, I started to prefix the variable with a lower dash, as is done in many examples:</p>
<pre><code>private _major: number;
get major(): number {
return this._major;
}
set major(major: number) {
this._major = major;
}
</code></pre>
<p>Now when I use the JSON.stringify() method to convert the object into a JSON string, it will use the variable name as the key: _major.</p>
<p>As I don't want the JSON file to have all keys prefixed with a lower dash, is there any possibility to make TypeScript use the name of the getter method, if available? Or are there any other ways to use the getter/setter methods but still produce a clean JSON output?</p>
<p>I know that there are ways to manually modify the JSON keys before they are written to the string output. I am curious if there is simpler solution though.</p>

40,082,259 | Docker compose yml static IP addressing | <p>I have such docker-compose.yml (not a full list here):</p>

- subnet: 172.16.1.0/24

</code></pre>
<p>After <code>docker-compose up</code> I got such an error:</p>
<blockquote>
<p>User specified IP address is supported only when connecting to
networks with user configured subnets</p>
</blockquote>
<p>So I'm creating subnet with <code>docker network create --gateway 172.16.1.1 --subnet 172.16.1.0/24 app_subnet</code></p>
<p>But this doesn't solve the problem because docker-compose creates the subnet with name dev_app_subnet on the fly. And my subnet is not used - I'm getting the same error.
The main purpose of doing this is to assign static IP for nginx service - open my project web url from etc/hosts file.</p>

40,082,896 | WCF как вмешаться в работающий метод и ограничить доступ строго 1 клиентом | Доброго дня. Стоит задача организовать WCF сервер для управления измерительной аппаратурой. В процессе изучения новой для меня темы WCF возникли начальные вопросы:
1. Как организовать аварийное прерывание работы со стороны клиента? Настроил асинхронные вызовы, нажимаю в клиенте кнопку "адски нагрузить сервер" - на стороне сервера в рамках реализации контракта запускаю `
while (!stop) i++;
`
Нажимаю кнопку с предложением серверу перекинуть
`static bool stop = false` в `true` - и безответно. Требуется понимание способов вмешательства в процесс вычислений - как грамотно извне на него повлиять, и в частности - прервать? Писать мультипоточный запуск еще и на стороне сервера и рубить его по запросу от клиента? Или можно проще?
2. Ну и до кучи, требуется ограничить доступ к управляющему аппаратурой серверу строго до 1 клиента. Пляски с бубном вроде найденного здесь же на форуме вараинта
`[ServiceBehavior(InstanceContextMode = InstanceContextMode.Single, ConcurrencyMode = ConcurrencyMode.Single)]`
и
`<behavior name="Throttled">
<serviceThrottling maxConcurrentCalls="1"
maxConcurrentSessions="1"
maxConcurrentInstances="1" />
</behavior>`
никак не мешают параллельно запущенному окошку клиента управлять сервером, что недопустимо. Рыть в сторону авторизации клиента, или все же есть счастливая строчка, решающая проблему? :) | <c#><wcf> | 2016-10-17 09:33:09 | LQ_EDIT |

<p>I found this neat implementation of a Set in go: <a href="https://github.com/fatih/set" rel="noreferrer">gopkg.in/fatih/set.v0</a>, but I'd prefer naming my sets with a more explicit name that <code>set.Set</code>, doing something like:</p>

<p>For now I've been trying the following <em>kinda</em> inheritance, but it's causing loads of errors when trying to use some functions like <code>func Union(set1, set2 Interface, sets ...Interface) Interface</code> or <code>func (s *Set) Merge(t Interface)</code>:</p>
<pre><code>type View struct {
set.Set
}
</code></pre>
<p>I'd like to know if there's a way to achieve what I want in a Go-like way, or if I'm just trying to apply my good-ol' OO practices to a language that discards them, please.</p>
