Jonathan Rentzsch (aka Wolf) is putting on a new conf named "C4: Chicago Mac Developer Conference", Oct 20-21. You can read more about it on his blog.

I'll be going, in fact I'm doing a presentation Saturday about Lua + Objc integration and how you can do cool things with it.

I think one of the ideas behind this conf is to bring back some of what MacHack was all about, which is cool because I was never able to make it to MacHack. I think I'll also be taking this trip as an opportunity to hang out in St. Louis for the following week. Should be a fun time.
