Qlobe

Qlobe is a fascinating example of quine in Ruby, submitted by a member of the Ruby core team - Yusuke Endoh.

Programs that output changed executable versions of themselves while managing to spin the globe and still remaining executable are cool, right?

To experience its magic, run the following

curl -fSSl https://gist.githubusercontent.com/shime/f0ebe84ca42c33b51d42/raw/5e74315dc6b6fe572f8a457536ad7eb17ad3f1e4/qlobe.rb > qlobe.rb; while true; do ruby qlobe.rb | tee temp.rb; sleep 1; mv -f temp.rb qlobe.rb; done

We want to create a function that will add numbers together when called in succession.

add(1)(2) == 3 // true

We also want to be able to continue to add numbers to our chain.

add(1)(2)(3) == 6 // true

To run bunch of Minitest tests in one go, without using Rake, use this command

$ ruby -e 'ARGV.each { |path| require "./#{path}" }' test/*.rb

What?

Most basic example of authenticating with Github in node.

How?

Clone this gist, change keys inside config.js and then hit npm install && node app.js.

Done?

What is this?

How do you compare date/times in RSpec?

If you do this

expect(Time.now.to_i).to eq Time.new(2014, 4, 2).to_i

Simple function that makes moving and renaming files in Vim much easier.

Usage

Place it in your ~/.vimrc.

I'm calling it with N here, map it to anything you like.

	<keyboard>
	<!-- resize windows with Alt + Direction -->
	<keybind key="A-Right">
	<action name="GrowToEdgeEast"/>
	</keybind>
	<keybind key="A-Left">
	<action name="GrowToEdgeWest"/>
	</keybind>
	<keybind key="A-Down">
	<action name="GrowToEdgeSouth"/>

	# https://domain.com -> https://www.domain.com
	server {

	var fs = require('fs'),
	path = require('path')

	var listFiles = function(dir, next){
	fs.readdir(dir, function(err, nodes){
	if (err) next(err)
	next(null, nodes.filter(function(node){
	return fs.lstatSync(path.resolve(dir) + "/" + node).isFile()
	}))
	})

	test "the Ember.RSVP.Promise works", ->

	promise = new Ember.RSVP.Promise((resolve, reject) ->
	Ember.run(null, resolve, "value")
	)

	Ember.run =>
	promise.then (actual) ->
	equal(actual, 'value', 'promise resolved with "hello"')
