Installing gcc 4.8 and Linuxbrew on CentOS 6

The GCC distributed with CentOS 6 is 4.4.7, which is pretty outdated. I'd like to use gcc 4.8+. Also, when trying to install Linuxbrew you run into a dependency loop where Homebrew's gcc depends on zlib, which depends on gcc. Here's how I solved the problem.

Note: Requires sudo privileges.

Deploying a subfolder to GitHub Pages

Sometimes you want to have a subdirectory on the master branch be the root directory of a repository’s gh-pages branch. This is useful for things like sites developed with Yeoman, or if you have a Jekyll site contained in the master branch alongside the rest of your code.

For the sake of this example, let’s pretend the subfolder containing your site is named dist.

Step 1

Remove the dist directory from the project’s .gitignore file (it’s ignored by default by Yeoman).

	var room = "abc123";

	socket.on('connect', function() {
	// Connected, let's sign-up for to receive messages for this room
	socket.emit('room', room);
	});

	// An `Object.observe()` "polyfill" using ES6 Proxies.
	//
	// Current `Object.observe()` polyfills [1] rely on polling
	// to watch for property changes. Proxies can do one better by
	// observing property changes to an object without the need for
	// polling.
	//
	// Known limitations of this technique:
	// 1. the call signature of `Object.observe()` will return the proxy
	// object. The original object needs to be overwritten with this return value.
