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The GCC distributed with CentOS 6 is 4.4.7, which is pretty outdated.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.

Add Git Branch Name to Terminal Prompt (Linux/Mac)

Open ~/.bash_profile in your favorite editor and add the following content to the bottom.

# Git branch in prompt.

parse_git_branch() {

Run rails new --help to view all of the options you can pass to rails new:

$ bin/rails new --help
Usage:
  rails new APP_PATH [options]

Options:
  -r, [--ruby=PATH]                                      # Path to the Ruby binary of your choice
                                                         # Default: /Users/eliot/.rbenv/versions/2.2.0/bin/ruby

Rails naming conventions

General Ruby conventions

Class names are CamelCase.

Methods and variables are snake_case.

Methods with a ? suffix will return a boolean.

	function mySexyMethod() {
	return new Promise(function (resolve, reject) {
	someAsync.method(params, function (err, data) {
	if (err) {
	return reject(err);
	}

	resolve(data);
	})
	});

	// Run this in the F12 javascript console in chrome
	// if a redirect happens, the page will pause
	// this helps because chrome's network tab's
	// "preserve log" seems to technically preserve the log
	// but you can't actually LOOK at it...
	// also the "replay xhr" feature does not work after reload
	// even if you "preserve log".

	window.addEventListener("beforeunload", function() { debugger; }, false)
