Far Cry: How the Fire Burns and Spreads (2012)
INTRO A few years ago, I got the opportunity to architect and code the fire propagation system in Far Cry 2. At that time, it was a gigantic task and it scared the hell out of me. Luckily, it turned out well enough. With the upcoming Far Cry 3, several people recently asked me how

What I wish someone had told me about tensor computation libraries
I get confused with tensor computation libraries (or computational graph libraries, or symbolic algebra libraries, or whatever they’re marketing themselves as these days).

To the brain, reading computer code is not the same as reading language

Shitlist Driven Development (2016)

Being good at coding competitions correlates negatively with job performance
A couple of days ago I watched a How Computers Learn talk by Peter Norvig. In this talk, Peter talked about how Google did machine learning and at one point he mentioned that at Google they also applied machine learning to hiring. He said that one thing that was surprising to him was that being a winner at…
