##How Homakov hacked GitHub and the line of code that could have prevented it

Please note: THIS ARTICLE IS NOT WRITTEN BY THE GITHUB TEAM or in any way associated with them. It's simply hosted as a Gist because the markdown formatting is excellent and far clearer than anything I could manage on my personal Tumblr at peternixey.com.

My thoughts on MessagePack

Hi. My name is Sadayuki "Sada" Furuhashi. I am the author of the MessagePack serialization format as well as its implementation in C/C++/Ruby.

Recently, MessagePack made it to the front page of Hacker News with this blog entry by Olaf, the creator of the Facebook game ZeroPilot. In the comment thread, there were several criticisms for the blog post as well as MessagePack itself, and I thought this was a good opportunity for me to address the questions and share my thoughts.

My high-level response to the comments

To the best of my understanding, roughly speaking, the criticisms fell into the following two categories.

This allows you to use the following video streaming services outside of the US from your Mac without having to use a proxy or VPN, so no big bandwidth issues:

	# This is the code from my 'There is No Such Thing as Metaprogramming' talk,
	# which premiered at the Arlington, VA Ruby Users Group on Feb 22nd.
	# Without the deliver and walk-through to the solution below this example
	# will be missing quite an important bit of content (mainly the tracking of
	# 'self' while developing the solution, but it still a useful read.

	# Here is the Toddler with no metajuju. Note that the developer, as well as
	# the code, is completely unuaware of the interpreter. A developer with a
	# background in compiled languages would be comfortable looking at this.
