The past 2 weeks I have mostly been busy with my firefighting service
since Greece is burning again this year, which means I couldn't focus on
GSOC as much. What I did do however, was organize the code and move
architecture-specific code to different files, and also started working
on improving performance and finding/fixing bugs.
