	}

	log($message) { # Define a method called "log" that takes a message as input
	$message \| Out-Host # Output the message to the console
	}
	}

	class TimeStampingLogger : Logger { # Define a class called "TimeStampingLogger" that inherits from "Logger"

PowerShell example demonstrating the Facade Design Pattern implementation

	class CPU {

	freeze() { "$this freezing" \| Out-Host }
	jump($position) { "$this jump to $position" \| Out-Host }
	execute() { "$this execute" \| Out-Host }

ronascentes / ChatMediator.ps1

Created July 30, 2024 13:53 — forked from dfinke/ChatMediator.ps1

Demonstrates the implementation of the Mediator Design Pattern in PowerShell

	<#
	Define an object that encapsulates how a set of objects interact.
	Mediator promotes loose coupling by keeping objects from referring to each other explicitly, and it lets you vary their interaction independently.
	#>

	class ChatMediator {
	$users

	ChatMediator() {
	$this.users = New-Object System.Collections.ArrayList

How to enable C# connection pool debugging logic for MongoDB

	var clientSettings = new MongoClientSettings();
	var traceSource = new TraceSource("MongoDB-CMAP-SDAM", SourceLevels.All);
	traceSource.Listeners.Clear(); // remove the default listener
	var logFileName = "<should be updated on the real path to a log file>";
	var listener = new TextWriterTraceListener(new FileStream(logFileName, FileMode.Append));
	listener.TraceOutputOptions = TraceOptions.DateTime;
	traceSource.Listeners.Add(listener);
	var eventSubscriber = new TraceSourceEventSubscriber(traceSource);
	Action<ClusterBuilder> clusterConfigurator = builder => builder.Subscribe(eventSubscriber); // if you don't use a MongoClient as singletone, it's better to share the same instance(so object.ReferenceEquals for them should return true) of this configurator, between all mongo clients
	clientSettings.ClusterConfigurator = clusterConfigurator;
