Linux, Unix, Network Systems Tutor

Looking for help understanding Linux and/or Unix, but in English? I can tutor you. If you want to learn how to become a "hacker" or learn some python, understand systems development, or talk about raspberry pi, I've got some tricks. Give me an email m_italix@hotmail.com or call at +420606507270. Only for Brno, no remote visits. We can do it at your place or talk about at some cafe.
