Jonathan "Wolf" Rentzsch, who has contributed a number of articles to TidBITS over the years, and who was a fixture at the MacHack/ADHOC conference, has decided that if we can't have MacHack any more, he'll just have to hack together his own conference. The result is the C4 conference, which will take place in Chicago on October 20th and 21st, 2006. It's looking like it will be short and sweet, with seven talks across the two days, along with appropriate food and libations. C4 costs $384 and attendance is capped at 75 people, so if you're interested, send email to c4@redshed.net to register. There are also three scholarship spots for students; see the conference Web site for details.
