I have reused the code enough to make a package out of it.

The python package is deposited at Github. with an example in Jupyter notebook.

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

Dear Rubyists,

I just lost a contract because of my code in a Rails project.

The specific code in question is related to a "posting a comment" feature. Here are the details:

In this project, "posting a comment" does not simply entail inserting a row into the database. It involves a procedure to yes, insert a row, but also detect its language, check for spam, send emails, and "share" it to Twitter and Facebook. I believe this algorithm should be encapsulated. I do not believe it belongs in a controller or a model. I do not believe Active Record callbacks should be used.

The "senior developer", whom is the stake holder's right hand man, said this:
