Using Selenium and Python to screenshot a javascript-heavy page

As websites become more JavaScript heavy, it's harder to automate things like screenshotting for archival purposes. I've seen examples and suggestions to use PhantomJS for visual testing/archiving of websites, but have run into issues such as the non-rendering of webfonts. I've never tried out Selenium until today...and while I'm not thinking about performance implications yet, Selenium seems far more accurate than PhantomJS...which makes sense since it actually opens a real browser. And it's not too hard to script to do complex interactions: here's an [example of how to log in to Twitter, write a tweet, upload an image, and send a tweet via Selenium and DOM element selection](https://gist.github.com/dannguyen/8a6fa49253c1d6a0eb92

Efficient Estimation of Word Representations in Vector Space

Introduction

Introduces techniques to learn word vectors from large text datasets.
Can be used to find similar words (semantically, syntactically, etc).

Regularization and variable selection via the elastic net

Introduction to elastic net

Regularization and variable selection method.
Sparse Representation
Exihibits grouping effect.
Prticulary useful when number of predictors (p) >> number of observations (n).
LARS-EN algorithm to compute elastic net regularization path.

Let's not localize programming languages. Please >_<

Feel free to fork and expand and/or add more languages as an example to why this would be horrible, and I'll add them here :)

How to stream the London 2012 Olympics

There have been several HOWTOs posted regarding streaming the 2012 Olympics using HTTP / SOCKS proxies via SSH and other similar methods. None of these actually work using the latest Flash on Mountain Lion (with Firefox, Chrome or Safari). Additionally, the third-party streaming sites don't provide BBC's amazing interface, which lets you quickly skip to individual competitors and events. However, setting up an OpenVPN server does work, with some tweaks. You'll get the exact same UX that people in England receive.

Get a Linode VM in the UK. The 512MB server for $20 works just fine. (If you want to use my referral link, go for it: http://bit.ly/OuzdVe)
Follow the standard OpenVPN installation documentation. (Basically, 'apt-get install openvpn' or 'yum install openvpn' and then follow these docs: http://openvpn.net/index.php/open-source/documentation/howto.html). For an OS X client, I prefer Viscosity: http://www.thesparklabs
