On the 10th of June, 2016, I’ve officially released my humble contribution to the radare2 community, radare2 Explorations, a free, open-source, practical book which teaches you the basics of using radare2 in an easy-to-follow manner.
Future plans
R2CON 2016 is coming, the first edition of a con focused on radare2! I am hoping to see some innovative use of radare2 in binary exploitation and reverse engineering.
At some point in time, I will be working on a second book which will cover some more advanced and lesser known features of radare2.
