I'm a member of Fail0verflow. I reversed most of the Wii, and wrote "savezelda", the exploit code for "The Twilight Hack" (later also used in many other exploits, some I wrote myself, some done by others).

I figured out the brain fart that allowed me to derive the PS3 private keys (presented here, https://fahrplan.events.ccc.de/congress/2010/Fahrplan/attachments/1780_27c3_console_hacking_2010.pdf, pp 123-125 for my work).

I wrote the first open source Open Firmware implementation (from scratch).

I am a GCC maintainer.
