A Common .ruby-version File For Ruby Projects

Background

I've been using this technique in most of my Ruby projects lately where Ruby versions are required:

Create .rbenv-version containing the target Ruby using a definition name defined in ruby-build (example below). These strings are a proper subset of RVM Ruby string names so far...
Create .rvmrc (with rvm --create --rvmrc "1.9.3@myapp") and edit the environment_id= line to fetch the Ruby version from .rbenv-version (example below).

Today I learned about another Ruby manager, rbfu, where the author is using a similar technique with .rbfu-version.

Installing git on CentOS 5 using yum

Since you're using CentOS 5, the default package manager is yum, not apt-get. To install a program using it, you'd normally use the following command:

$ sudo yum install <packagename>

However, when trying to install git this way, you'll encounter the following error on CentOS 5:

	# Nothin' special here: just Resig's pretty date function ported to Ruby
	# http://ejohn.org/blog/javascript-pretty-date/

	def pretty_date(stamp)
	now = Time.new
	diff = now - stamp
	day_diff = ((now - stamp) / 86400).floor

	day_diff == 0 && (
	diff < 60 && "just now" \|\|

	require 'net/http'

	def post_xml url_string, xml_string
	uri = URI.parse url_string
	request = Net::HTTP::Post.new uri.path
	request.body = xml_string
	request.content_type = 'text/xml'
	response = Net::HTTP.new(uri.host, uri.port).start { \|http\| http.request request }
	response.body

	Lightweight Backbone Cache
	Mike Knoop, 2012 (knoopgroup.com, zapier.com)

	Simply execute this script file sometime after you load Backbone.
	It hooks into the Backbone sync function to give a lightweight local
	cache for models and collections. Will work for both models and collections.
	Only GET requests are eligible for cacheing and caches are stored by URL.

	Backbone.Model::nestCollection = (attributeName, nestedCollection) ->
	#setup nested references
	for item, i in nestedCollection
	@attributes[attributeName][i] = nestedCollection.at(i).attributes

	#create empty arrays if none
	nestedCollection.bind 'add', (initiative) =>
	if !@get(attributeName)
	@attributes[attributeName] = []
	@get(attributeName).push(initiative.attributes)
