Facial Recognition System for $60

The New York Times ran an experiment using a public video stream from Bryant Park in Midtown Manhattan. They collected publicly available photos of people that worked near the park and then ran one day's worth of footage from the public video stream through Amazon's commercial facial recognition service at the cost of approx $60. Over a nine hour period it detected 2,750 faces, including an 89% match of a college professor from his employer's website headshot.

The Problems With Software Hiring

Nikita Prokopov has a superb blog post about how a lot of tech companies approach the hiring of software engineers incorrectly.

I could not agree more with everything in this post!

Generative Aphex Twin

Alex Bainter has a good explainer post on Medium about how he used Markov Chains to generate a much longer version of Aphex Twin's aisatasana. Using a JSON representation of a MIDI file of the track, he built a Markov Chain system to generate over four million unique phrases which can play for over 451 days without repetition of a phrase. The result is available to listen to on generative.fm.
