Michael Steil is a professional in their field. Colleagues describe him as "I met Michael at the 24C3, where we accidently had very similar interest. He was very open and came to me straight ahead, without any normal nerd hesitance one is used from nerd environments ;-). He kept on amazing me - every time we were talking about cool things to do, he was either implementing it already, has at least read several papers about it and was almost ready to do so or at least talked with somebody about the same topic. But he isn't only knowledgeable in the current questions of in-kernel-fun. Michael is the one person I know I'd go to for any 8-bit questions. He disassembled several basic interpreters, knows all Z80 assembly opcodes inside out and even has the skills to explain all of that easily!"
