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.

Barnes-Hut is O(n log n) http://en.wikipedia.org/wiki/Barnes%E2%80%93Hut_simulation

There is a nice big list here: http://cstheory.stackexchange.com/questions/1168/what-papers...

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.

I did that some time ago: https://github.com/jbochi/gifstreaming

I've implemented the FOV algorithm suggested on this article without ray casting in Javascript: https://s3.amazonaws.com/jbochi/layout.html

It was an experiment for a game that I was working on, but I never finished it: https://github.com/jbochi/duelo

There is on open source a Nginx module that streams RTMP and creates HLS segments that looks promising: https://github.com/arut/nginx-rtmp-module

There are also red5 (http://www.red5.org/) and rtmpd (http://www.rtmpd.com/)

If you liked this post, you will probably find this article about other probabilistic data structures interesting too: http://highlyscalable.wordpress.com/2012/05/01/probabilistic...

Fabrice Bellard a genius: http://en.wikipedia.org/wiki/Fabrice_Bellard

It would be nice if the resume included popular projects the user has contributed to.

What about unit testing? He constantly tests the changes manually, but I don't see any automated tests.

tl;dw(atch): Use the ImportXML function and XPath: https://docs.google.com/support/bin/answer.py?answer=155184

Interesting! I've created an open-source library in Go to hide text on images: http://strogonoff-demo.appspot.com/

I built this Nose plugin inspired by Google's CI system: http://googletesting.blogspot.com/2011/06/testing-at-speed-a...

Hope it's useful.

Really nice idea. I have created something similar but I try to create a playlist for those who have last.fm accounts: http://lastvj.appspot.com

Create something that makes people so happy they will tell their friends about it.
