Take care of the sense, and the sounds will take care of themselves.
If you was unable to attend Developers Academy 2 and still want to see sessions there, you are more, then welcome to do it. Here link to the recording of my session. And here is the presentation. The quality of the recording is awful, as well as whole hosting site quality. It seemed like "Gisha Hadasha" has no QA and particle employed student to make sites. However, if you still want to see the screencasts of the sessions, go there.
See screencast "WPF for developers (or optimizing your WPF application)" >>
