Get information about the Authenticode signature from a signed script by using the Get-AuthenticodeSignature-cmdlet: Get-AuthenticodeSignature .\MyScript.ps1 | Format-List *

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...

Sometimes a new Java programmer will write code like this: public void check(boolean ok) { if (ok == true) { // Note 'ok == true' System.out.println("It is OK"); } } An experienced programmer would spot that as being clumsy and want to rewrite it as: publ...

If you are adding new rows and updating existing data. You need two additional parameters: --check-column : A column name that should be checked for newly appended and updated data. date, time, datetime and timestamp are suitable data types for this column. --last-value : The last value that su...

Local variables - Those declared within a procedure (subroutine or function) of a class (or other structure). In this example, exampleLocalVariable is a local variable declared within ExampleFunction(): Public Class ExampleClass1 Public Function ExampleFunction() As Integer Dim exa...

Now that you're running Parse Server, it is time to save your first object. We'll use the REST API, but you can easily do the same using any of the Parse SDKs. Run the following: curl -X POST \ -H "X-Parse-Application-Id: APPLICATION_ID" \ -H "Content-Type: application/json" \...

function wait(ms) { return new Promise(function (resolve, reject) { setTimeout(resolve, ms) }) }

file:write_file("myfile.txt", ["Hi " [<<"there">>], $\n]).

["Guten Tag " | [<<"Hello">>]]. [<<"Guten Tag ">> | [<<"Hello">>]]. [$G, $u, $t, $e, $n , $T, $a, $g | [<<"Hello">>]]. [71,117,116,101,110,84,97,103,<<"Hello">>].

Data_1 = [<<"Hello">>]. Data_2 = [Data_1,<<" Guten Tag ">>].

["Guten tag " | <<"Hello">>]. In the shell this will be printed as ["Guten tag "|<<"Hello">>] instead of ["Guten tag ",<<"Hello">>]. The pipe operator will create an improper list if the last element o...

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

Some programmers think that it is a good idea to save space by using a null to represent an empty array or collection. While it is true that you can save a small amount of space, the flipside is that it makes your code more complicated, and more fragile. Compare these two versions of a method for ...

On StackOverflow, we often see code like this in Answers: public String joinStrings(String a, String b) { if (a == null) { a = ""; } if (b == null) { b = ""; } return a + ": " + b; } Often, this is accompanied with an asse...

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...

Use vectors to calculate incremental [x,y] from [startX,startY] to [endX,endY] // dx is the total distance to move in the X direction var dx = endX - startX; // dy is the total distance to move in the Y direction var dy = endY - startY; // use a pct (percentage) to travel the total distance...
