Helpfully handling Command Not Found in PowerShell

About CommandNotFoundAction

In PowerShell there is a callback ("Action") that is called when a command lookup fails through normal means. The purpose of this callback is to allow you to add your own command-resolution, and there are a lot of community hacks out there already:

• You could add support for new command types, like

using namespace System.Collections.Generic; using namespace System.Text

Add-Type -TypeDefinition '
    using System;
    using System.Runtime.InteropServices;
    using System.Text;

    public class WindowTools
    {
        public delegate bool EnumWindowsProc(IntPtr hWnd, int lParam);

You should not use the Open SSH client that comes with Git for Windows. Instead, Windows 10 has its own implementation of Open SSH that is integrated with the system. To achieve this:

1. Start the ssh-agent from Windows Services:

• Type Services in the Start Menu or Win+R and then type services.msc to launch the Services window;
• Find the OpenSSH Authentication Agent in the list and double click on it;
• In the OpenSSH Authentication Agent Properties window that appears, choose Automatic from the Startup type: dropdown and click Start from Service status:. Make sure it now says Service status: Running.

2. Configure Git to use the Windows 10 implementation of OpenSSH by issuing the following command in Powershell:

git config --global core.sshCommand C:/Windows/System32/OpenSSH/ssh.exe

Powershell Performance: Adding to arrays is slow

A common pattern in many languages adds an element to an array or list

elements = []
for x in range(10000):
 elements.append(x)
