Notes on computers and engineering

This is a repository of some of my notes on the topic of computer technology. They are mainly intended to be notes to myself though I have had it in the back of my mind that other people might want to read some of them. There are also some examples of Minecraft creations.

Most are not meant to be academical with two exceptions; a report I wrote for the course Introductory Software Engineering about SPARK Ada in 2010 and my Bachelor's thesis from May 2012(document is in Swedish and hosted by Chalmers University of Technology).
