This is, by the way, the dirty secret of the machine learning movement: almost everything produced by ML could have been produced, more cheaply, using a very dumb heuristic you coded up by hand, because mostly the ML is trained by feeding it examples of what humans did while following a very dumb heuristic. There's no magic here. If you use ML to t... See more

That week in summer 2015 our startup Paribus had grown 20% w/w, our biggest problem ... See more

After building +40 apps over the last decade, I think the most valuable skill is an ability to correctly sequence the things that need to validated for the concept to work. For example: 1. Users need to share the app X number times for the app to have a basis to grow 2. The shares then need to convert to downloads at X rate 3. Then, X% of users n... See more
