Bandits are probably one of the most underrated machine learning algorithms. One possible application is recommendation systems. Shameless self promotion. I wrote an article about it: https://towardsdatascience.com/how-not-to-sort-by-popularity...

We are just exporting the matrices. Nothing fancy.

I did something similar in Javascript. My implementation uses the Runge-Kutta algorithm, that is more stable. My GUI does not allow planet creation, but it shows several stable configurations, including the 13 recently found three body planar orbit configurations.

Riak CS is S3 compatible.
I have a very similar problem and end up writing a python script that copies the files to cassandra and Nginx + Lua to serve them using lua-resty-cassandra. The read/write throughput is still not as good as I was expecting though.

This article is the best introduction to the topic in my opinion: http://steve.vinoski.net/pdf/IC-Rediscovering-Distributed-Sy...
Another good reference for understanding distributed databases is: http://cs-www.cs.yale.edu/homes/dna/papers/abadi-pacelc.pdf

It would be interesting to see the same data broken down by year. Lua, Clojure, and Go are at about the same position, but I wonder which one is gaining traction. Probably Go.

This blog post is a nice survey about other interesting probabilistic data structures: http://highlyscalable.wordpress.com/2012/05/01/probabilistic...

It's hard to believe that JavaScript and Transact-SQL have more or less the same popularity (1.569% against 1.559%). That's why I don't care about this index anymore.

Ilya Grigorika, the presentation author, has also written a book called High Performance Browser Network that I highly recommend if you are interested on the subject.
There is a free online version available at http://chimera.labs.oreilly.com/books/1230000000545/index.ht...

With OpenCV you can also do face detection and feature recognition for smarter crops. Thumbor does that and is used in a large scale at globo.com: https://github.com/globocom/thumbor.
