Who needs days off? If work is your mistress, give her a little extra loving this weekend. At the Freebase Hack Day , dataheads will be getting together to unconference about Open Government applications and other topics at Metaweb Technologies from 10-6 p.m. on Saturday. Code Camp is taking over Foothill Community College for a fluff free weekend about, well, code. Whether you talk Ruby or Hadoop, geek out at 100-plus sessions at the annual event by developers for developers. Meanwhile, SIPACON 08 will be tackling social media and enterprise at Hewlett-Packard from 8:30-4 p.m. Find out how big business is planning to actually make money on Web 2.0. And finally, a quick message about Proposition 8.
