Good conference to have in general. I'd suspect most programmers have a natural interest for different languages/paradigms but practically using them in concert often reveals subtle problems.

I have a decent background in Prolog (hardly an expert) and know it's often a good tool for the job but often shy away from using it regardless.

I hope the "Erlang in multi-lingual systems" talk (all of them for that matter) will be available later :)

"Why should you learn to program Commodore 64 this year?" sounds like the exact kind of talk I'd enjoy.

Prices seem very fair and I love that a %age goes to CodeStarter.
