Apparently, one of the authors of this paper lost it due to a computer failure. I've got it on my hard drive, so I've reposted it for them (or anyone else).
Fast Solution of l1-norm Minimization Problems When the Solution May be Sparse

There's a good visual comparison of programming fonts over on Coding Horror.
I have to cast my vote for Pragmata, in 11 pt as he shows. Yes, it is expensive for a font, but then I look at a screen full of it for 40+ hours a week. It paid for itself long ago.
As I mentioned in my previous post, the Netflix Prize is nearing the one year point tomorrow, with a $50,000 payoff. It is turning into a good geek race.
The second and third place teams, Gravity and Dinosaur Planet have combined to form "When Gravity and Dinosaurs Unite". They now have a first place score of 8.38% improvement. This edges out BellKor, who also improved their score to 8.38%.
While the new combined team is listed first, they may not actually win the progress prize. To prevent any information leakage, the Leaderboard only shows the improvement of a randomly selected half of the test set. It the other half of the test set that actually counts. So with scores identical to four decimals, either may be ahead.
It will interesting to see who pulls it out tomorrow, and if there will be any better entries.
