Motivation

  • Partial application is fundamental to functional-style programming
  • It is the binding of arguments to parameters before a function is invoked
  • This technique is often used by ECMAScript developers who are:
    • seeking to avoid the use of new and/or this
    • deliberately trying to avoid function genericism
    • trying to improve consistency of style
  • Partial application is currently supported by Function.prototype.bind, but the syntax is verbose, and the target of the bound function comes first, diluting the semantic
  • Writing a custom function to provide partial application is straightforward (indeed there are many open source libraries providing this such as _.partial), however developers taking this approach are constrained in their ability to achieve syntactic tenseness lest they surprise other developers
  • A terse, native syntax for partial application that does not affect the target of a function will improve consistency, clarity of intent and legibility

How to stream the London 2012 Olympics

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.
