In 2015 I ran a training session on BTRFS and ZFS. Here are the notes for BTRFS updated for the latest versions of everything when running on KVM. You can do all the same exercises on a non virtual machine, but it’s safest not to do this on a machine with important data. For the […] This is a program I wrote to benchmark SMTP servers. I started work on this because I need to know which mail server will give the best performance with more than 1,000,000 users.

I won’t tell people […] This post has a list of educational apps for Android phones and tablets that I have discovered. I can’t claim that each app is the best for it’s purpose, but I’ve tested out each one and found it to be useful.
