learning in public - july 2022 edition

Learning in public is gonna be a new series of blog posts in order to share some cool stuff I’ve been up to! I’ve been up to some stuff lately!

Mainly to take some ideas for my Go course that I’ll be launching there, and also to get more formal training on ansible, my experience was always been driven by problems at work!
