Known knowns, known unknowns, and those pesky unknown unknowns are under attack at the 17th Usenix Security Symposium today. Grab your best conspiracy theory and head on over to the Fairmont in San Jose for this week long conference on cyber security. Attendees will be taking on all manner of web threats, including: botnets, malware, and bandwith based attacks. If the only thing your counting down to is Oracle Open World, the Enterprise 2.0 Bootcamp can give you a quick fix till September. Today's free 1-Day workshop at the Oracle Conference Center puts collective intelligence to work for you. For a bit of meetup fun, tonight the Social Media Club is getting network-y at the British Bankers' Club in Menlo Park while the Silicon Valley Flicker meetup draws photo-loving society to Campbell.
