Michael Lehman has uploaded
the videos from the various presentations that we had at
the Lang.NET Symposium.
Gough on running Ruby on the CLR.
Barnett on Spec# (Programming with contracts).
Hejlsberg on the new LINQ extensions. A great
introduction to the new data and XML processing facilities in
C# 3.0 and how these are built on top of a few small changes
to the language.
Syme talks on F# and delivers a great live demo.
Hugunin shows IronPython, this was done very close to 1.0
and Cory on SecondLife. I absolutely loved Jim's
Lam on bridging the Ruby interpreter and the CLR
(different from John's presentation. He also pulls an
incredible demo with Ruby and Avalon.
There are more talks there, but I missed a few of those
talks (one of the talks uses Mono's C# compiler as the base
for their research.
And my own presentation here,
the usual Mono stuff that I talk about.
