Hi. I'm looking for an interesting conference which worth to visit and which is connected with programming. It may not to be about game industry. I work as a programmer in one company and i deal with C#, physx engine and graphics and i like these things. I'm thinking of siggraph but maybe you can suggest something else? Thanks.

Siggraph would be fun. I've gone to Google I/O the last few years, and if you can get tickets, that's a fun conference to attend (plus they're in the habit of giving you free stuff there).
