I'm Christophe, 30 y.o., and will live in Poland until I finally move to the Netherlands
As for education... I've got a master's degree in polymer chemistry, but got into IT instead. I got into GNU/Linux in 2012 and have used it ever since (Debian at home, Fedora at work - when I worked for a cloud VoIP company as a tech support engineer and software tester). XP was the last Redmond system I used
Then I came to the Book Art Museum and did all kinds of technical stuff, from mechanical and plumbing repairs to network administration, electronics, and - recently - programming.
I've been using the Raspberry for almost 2 years now. First B, then B rev. 2, B+ and 2B... One works as a LAN router (uses multiple 802.1q VLANs on the single PHY, and a Netgear smart switch; works under OpenWRT), another is used for testing, experimenting or programming Arduinos and other chips via UART. Lastly, a few ended up in computer control interfaces for Monotype type casting machines.
I also laid my hands on an Arduino, Pro Mini precisely: a synchronized control for multiple GoPro cameras for 3D/VR capture, forked off orangkucing/MewPro.
The Raspberry certainly did what it was meant for - got me into programming... I started with Python in Apr 2014, and now I'm not bad with it although I could use some help with design patterns, software architecture etc. I can do a thing or two in C as well, but it's not my favourite language. All those variable declarations, braces and semicolons... I prefer something more Pythonic
