Consider a simple asynchronous method: async Task Foo() { Bar(); await Baz(); Qux(); } Simplifying, we can say that this code actually means the following: Task Foo() { Bar(); Task t = Baz(); var context = SynchronizationContext.Current; t.ContinueWith(task...

To disable synchronization context you should call the ConfigureAwait method: async Task() Foo() { await Task.Run(() => Console.WriteLine("Test")); } . . . Foo().ConfigureAwait(false); ConfigureAwait provides a means to avoid the default SynchronizationContext capturi...

An Odd-Even Sort or brick sort is a simple sorting algorithm, which is developed for use on parallel processors with local interconnection. It works by comparing all odd/even indexed pairs of adjacent elements in the list and, if a pair is in the wrong order the elements are switched. The next step ...

To get started we need a factory that produces WebClients. public class ClientFactory { private Map<String, WebClient> cache = new HashMap<>(); public enum RESTClient { PORTAL; } public WebClient fetchRestClient(RESTClient restClient) { if (th...

To connect to a server we must use SSH on the client as follows, # ssh -p port user@server-address port - The listening ssh port of the server (default port 22). user - Must be an existing user on the server with SSH privileges. server address - The IP/Domain of the server. For a real wor...

Both connecting to a remove SSH server and accepting SSH connections require installation of openssh Debian: # apt-get install openssh Arch Linux: # pacman -S openssh Yum: # yum install openssh

this can also be cv-qualified, the same as any other pointer. However, due to the this parameter not being listed in the parameter list, special syntax is required for this; the cv-qualifiers are listed after the parameter list, but before the function's body. struct ThisCVQ { void no_qualifi...

C++11 Similarly to this cv-qualifiers, we can also apply ref-qualifiers to *this. Ref-qualifiers are used to choose between normal and rvalue reference semantics, allowing the compiler to use either copy or move semantics depending on which are more appropriate, and are applied to *this instead of...

Custom Post Type Archive: To create an archive template for a custom post type you have to set the has_archive argument equal to true in your register_post_type() function. In the example below a custom post type is created for an Event post type. add_action( 'init', 'create_events_post_type' );...

You could describe variable affectation in different ways. Typed int a = 1 int a := 1 let int a = 1 int a <- 1 No type a = 1 a := 1 let a = 1 a <- 1

As long as the function name, return statement and parameters are clear, you're fine. def incr n return n + 1 or let incr(n) = n + 1 or function incr (n) return n + 1 are all quite clear, so you may use them. Try not to be ambiguous with a variable affectation

Akka Streams allows you to easily create a stream leveraging the power of the Akka framework without explicitly defining actor behaviors and messages. Every stream will have at least one Source (origin of the data) and at least one Sink (destination of the data). import akka.actor.ActorSystem impo...

The BigInteger class has a constructor dedicated to generate random BigIntegers, given an instance of java.util.Random and an int that specifies how many bits will the BigInteger have. Its usage is quite simple - when you call the constructor BigInteger(int, Random) like this: BigInteger randomBigI...

By utilizing the pre_save we can determine if a save action on our database was about updating an existing object or creating a new one. In order to achieve this you can check the state of the model object: @receiver(pre_save, sender=User) def pre_save_user(sender, instance, **kwargs): ...
