Often you might need to execute an unsigned script that doesn't comply with the current execution policy. An easy way to do this is by bypassing the execution policy for that single process. Example: powershell.exe -ExecutionPolicy Bypass -File C:\MyUnsignedScript.ps1 Or you can use the shorthan...

When signing personal scripts or when testing code signing it can be useful to create a self-signed code signing certificate. 5.0 Beginning with PowerShell 5.0 you can generate a self-signed code signing certificate by using the New-SelfSignedCertificate-cmdlet: New-SelfSignedCertificate -Friendl...

CLISP has an integration with GNU Readline. For improvements for other implementations see: How to customize the SBCL REPL.

Rust's coherence rule requires that either the trait or the type for which you are implementing the trait must be defined in the same crate as the impl, so it is not possible to implement Serialize and Deserialize for a type in a different crate directly. The newtype pattern and Deref coercion provi...

PHP is able to parse a number of date formats. If you want to parse a non-standard format, or if you want your code to explicitly state the format to be used, then you can use the static DateTime::createFromFormat method: Object oriented style $format = "Y,m,d"; $time = "2009,2,26&...

ExecutorService ExecutorService executor = Executors.newFixedThreadPool(50); It is simple and easy to use. It hides low level details of ThreadPoolExecutor. I prefer this one when number of Callable/Runnable tasks are small in number and piling of tasks in unbounded queue does not increase m...

Let's have a look at various options to wait for completion of tasks submitted to Executor ExecutorService invokeAll() Executes the given tasks, returning a list of Futures holding their status and results when everything is completed. Example: import java.util.concurrent.*; import ja...

Executors returns different type of ThreadPools catering to specific need. public static ExecutorService newSingleThreadExecutor() Creates an Executor that uses a single worker thread operating off an unbounded queue There is a difference between newFixedThreadPool(1) and newSingleThreadE...

Consider the following list comprehension Python 2.x2.7 i = 0 a = [i for i in range(3)] print(i) # Outputs 2 This occurs only in Python 2 due to the fact that the list comprehension “leaks” the loop control variable into the surrounding scope (source). This behavior can lead to hard-to-find...

Direct loop foreach ($colors as $color) { echo "I am the color $color<br>"; } Loop with keys $foods = ['healthy' => 'Apples', 'bad' => 'Ice Cream']; foreach ($foods as $key => $food) { echo "Eating $food is $key"; } Loop by reference In the fo...

Custom Renderer help to allows to add new properties and render them differently in native platform that can not be otherwise does through shared code. In this example we will add radius and shadow to a boxview. Firstly, we should create custom control in PCL project, which will declare some requir...

In this exemple, we want to execute code which is stored in a string format. # the string str <- "1+1" # A string is not an expression. is.expression(str) [1] FALSE eval(str) [1] "1+1" # parse convert string into expressions parsed.str <- parse(text="1+1...

For null check in method Object nullableObject = methodReturnObject(); if (Objects.isNull(nullableObject)) { return; } For not null check in method Object nullableObject = methodReturnObject(); if (Objects.nonNull(nullableObject)) { return; }

Objective-C NSPredicate *predicate = [NSPredicate predicateWithFormat: @"self[SIZE] = %d", 5)]; Swift let predicate = NSPredicate(format: "self[SIZE] >= %d", 5) In this example, the predicate will match items that are arrays with length of at least 5.

Postscript is a dynamic-namespacing or LISP 1 language. But it provides the tools to implement local variables in procedures and other effects needed to implement algorithms. For local names in a procedure, make a new dictionary at the start and pop it at the end. /myproc { 10 dict begin ...
