I have grown a beard since 2004 and worked with Unices since 1996. Both were not cool at that time
I have been around computers since 1987 when I first seen a Sinclair Spectrum clone.
Since then I worked with countless CPU architectures (from petty microcontrollers
to multicore SPARC) and programming languages.
I am a hacker at heart and I do not mind improvising some hardware when it is necessary
or going into Assembly Language if it is a must.
