I'll be at hack.lu (21-24 October) for a talk (and a workshop) about radare2, with maijin, and xvilka. If I can manage to get a Visa, I'll also be at ZeroNights (13-14 November), in Russia, for a 4 hours workshop, still about radare2, with xvilka! Both in English. I hope that my co-speakers have a worse accent than mine ;)
On a side note, I'll likely do another (smaller) talk, at the utbm, about common C-related mistakes/vulnerabilities, and their exploitation, fall october; stay tuned!
