DTrace: Google Tech Talk
I've been hearing about DTrace for years now and I kind of knew what it was and that I would like to have it. In the back of my mind I've been waiting for it to appear in FreeBSD (although this seems to be faltering a little) so I could play with it.
Well one of the engineers from Sun that gave birth to DTrace has done a google tech talk about DTrace and it's very interesting indeed. Highlights for me were the amazing instrumentation of Python which I will definitely use. He also muses on the lack of support for DTrace on linux and tries to gather a posse of developers from google to kick it off, porting DTrace to Windows and how he can't find a good book on programming.
