Great training, attend if you can!
This training is amazing. Peter starts with the foundation of all exploiting: the OS and how it talks to the CPU/memory, and how that is important to exploitation. His way of describing complex concepts in simple drawings is amazing and really makes you understand what you are doing.
We wrote exploits for all sorts of stuff, and what seemed like magic has been neatly reduced to comprehensible, understandable steps.
Long story short, great training, great material, attend if you can.
