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. This allows you to create a zero filled file of a predefined size, fantastic. It's a small, but powerful, command that is included with every Windows install but let's assume you need a PowerShell native method for creating a zero filled file, what might that look like?
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. Yes, building your application in a way that you can fail over to a secondary system but that never seemed kosher to me as a patching strategy unless you're working at scale and already account for high availablity. I've implemented some long runner server software in PowerShell and using some of the features it's gleaned from Unix scripting you can hot load new code into them on the fly.
