Hello, everyone, my name is Dmitry Vostokov, and I teach this training course. 7

The prerequisites are hard to define. Some of you have software development experience and some not. However, one thing is certain that to get most of this training you are expected to have basic troubleshooting experience. Another thing I expect you to be familiar with is hexadecimal notation and that you have seen or can read programming source code in some language. The ability to read assembly language has some advantages but not necessary for this training. Windows memory dump analysis experience may really help here and ease the transition but not absolutely necessary. If you have read either Accelerated Mac OS X Core Dump Analysis or Accelerated Windows Memory Dump Analysis book or both, you may find the similar approach here.
