I picked up an issue of Foreign Affairs while flying back to NYC from SFO. It features this long interview with U.S. General Stanley McChrystal and I thought it was pretty interesting how striking some of the similarities are between fighting in a war and developing software.

Slides from the talk. Slightly edited because (a) some of the slides make little sense taken out of context (b) Slideshare seem to have problem converting some of the stuff. Collaborative filtering at Spotify from Erik Bernhardsson

Calculating cosine similarities using dimensionality reduction

This was posted on the Twitter Engineering blog a few days ago: Dimension Independent Similarity Computation (DISCO) I just glanced at the paper, and there's some cool stuff going on from a theoretical perspective.

Tumblr's awesome project names

Not sure how I managed to miss this, but I'm watching this Tumblr presentation and they talk about their projects named after Arrested Development topics: Gob, Parmesan, Buster, Jetpants, Oscar, George and Motherboy. Still, the best software project name is probably still Apple's BHA.
