I am Peter Wu (a.k.a. Lekensteyn), CS student at the University of Technology in Eindhoven, programmer, Free/Libre Open Source Software enthusiast, Arch Linux user and twin (hi Rob!).
Got some Linux, Ubuntu or programming question? I might already have answered them for you at Stack Exchange!
Of course you can also get in touch with me by mail: email@example.com, or Twitter (@Lekensteyn), and my RPi keeps me active on Freenode IRC as Lekensteyn.
