How to create a Windows USB boot stick using Ventoy

I ran into a situation recently where I needed to create a Windows 10 bootable USB stick.

The benefit of buying one as opposed to borrowing one was that […]

How to: Fix weird ENVI startup file issues

This post is more a note to myself than anything else – but it might prove useful for someone sometime. In the dim and distant mists of time, I set up a startup file for ENVI which automatically loaded a specific image every time you opened ENVI. I have no idea why I did that […]
