I'm a computer technician by trade and a hobbyist programmer...of course, I'm also a musician and an artist and a whole lot of other things that ultimately leave me with no free time.
I fix computers for a living, but in my spare time I delve into the vast sea of information regarding what makes them tick...
I collect computers as well, mostly for use in BOINC (distributed computing), on which my username is NullCoding* - the asterisk is intentional; it's a team thing.
