#43I'm also building a data driven (mostly NLP) portfolio optimizer, based on expected utility theory! It's a naive model, but it also has statistical bounds on its efficiency relative to the regret, which is an interesting bonus.

#44I wonder if you and I are working on the same thing. ;) I'm building infrastructure that I'm hoping will be needed to complete the Stockfighter trading puzzles. ( Hoping , because it's entirely possible that I will be lied too far less than the documentation leads me to believe, and I won't need all of this sanity checking.)

#47Atmospheric cube satellite kits for STEM programs: http://www.trimtab.space/ We 3D print a cube satellite, send them to the school, they fill it with their experiments (conditions are extreme at 100,000 ft.) and we send it up on a high altitude balloon. We've got a 3U launch planned a few weeks from now.
