Business secrets from terrible people

I get bored reading management books very easily and lately I’ve been reading about a wide range of almost arbitrary topics. One of the lenses I tend to read through is to see different management styles in different environments. It tu...

New approximate nearest neighbor benchmarks

As some of you may know, one of my side interests is approximate nearest neighbor algorithms. I’m the author of Annoy, a library with 3,500+ stars on Github as of today. It offers fast approximate search for nearest neighbors with the ad...

Interviewing is a noisy prediction problem

I have done roughly 2,000 interviews in my life. When I started recruiting, I had so much confidence in my ability to assess people. Let me just throw a couple of algorithm questions at a candidate and then I’ll tell you if they are good...
