Creating Zero Filled Files with PowerShell

There are times where you'd like to create a dummy file for testing, if you're on Windows you may be familiar with the 'fsutil file createnew' command.

Powershell Live Code Loading (kind of)

Hot code loading is a feature of languages that allows a developer to load new code into a running system without stopping the process. This has some clear benefits on servers, security and feature patches can be added without a risk of downtime.
