• Hacker's guide to Neural Networks

  My personal experience with Neural Networks is that everything became much clearer when I started ignoring full-page, dense derivations of backpropagation equations and just started writing code. Thus, this tutorial will contain very little math (I don't believe it is necessary and it can sometimes even obfuscate simple concepts). Since my background is in Computer Science and Physics, I will instead develop the topic from what I refer to as hackers's perspective. My exposition will center around code and physical intuitions instead of mathematical derivations. Basically, I will strive to present the algorithms in a way that I wish I had come across when I was starting out.

• MetricsGraphics.js - a library based on D3.js, optimized for visualizing and laying out time-series data

  MetricsGraphics.js is a library built on top of D3 that is optimized for visualizing and laying out time-series data. It provides a simple way to produce common types of graphics in a principled, consistent and responsive way. The library currently supports line charts, scatterplots and histograms as well as features like rug plots and basic linear regression.

• gka/chroma.js · GitHub

  Chroma.js is a tiny JavaScript library (8.5kB) for all kinds of color conversions and color scales.

• kripken/sql.js · GitHub

  sql.js is a port of SQLite to JavaScript, by compiling the SQLite C code with Emscripten. no C bindings or node-gyp compilation here.

• jas-/secStore.js · GitHub

  It is named secStore.js because not only will this plug-in assist you in transparent storage & retrieval of client data, but it will optionally provide a layer of security for said data with the use of the SJCL (Stanford Javascript Crypto Libraries).
