So, Team Bandersnatch (bi and I) got in the top-50, which entitles us to t-shirts. I did one problem, he did three. :)
I'd post my solution to problem 6, like he did, but it looks fugly - it took a lot of hammering to make the square peg fit in the star-shaped hole.
Some of the problems were hardcore. None of the teams did problems 3 or 4.
A company called D-Wave demo'ed an alleged superconducting 16-qubit quantum computer. Their PR department seems to claim it's able to solve NP-complete problems in polynomial time, which sounds like BS, but the thing looks pretty darn cool anyway. In both senses of the word (ha, ha).
