Would any Rails developer consider this bad practice?

If so, why?

I am overriding the external_url= setter to ensure URLs start with http://. I’m doing this before any validation because I don’t want to bother the user who enters example.com/foo/bar without http://. I don’t plan on validating the URL at all anyway.

def external_url=(url)
  if !url.match /^https?:\/\//i
 url = "http://#{url}"

This is how I handle snappy taps on iOS.

I create a little jQuery/Zepto “plugin” function:

$.fn.onClickOrTouch = (callback) ->
  if window.ontouchend != undefined # insanely clever touch detection
    this.each -> this._touchMoveCount = 0

In most browsers, event is an ever-existing JavaScript variable which value changes depending on context.

Safari, Chrome and Opera:

<script>
  window.onload = function() {
    console.log(event) // Event (type: "load")
  }
  console.log(event) // undefined

	[alias]
	unstage = reset HEAD # unstage
	clear = reset --hard HEAD # erase uncommited file edits (destructive!)
	uncommit = reset HEAD~1 # erase last commit but keeps related file edits
	rollback = reset --hard HEAD~1 # erase last commit and related file edits (destructive!)

	# I often need this IP for testing local websites in VirtualBox

	echo -n `ifconfig \| grep -Po "(?<=inet )\d\.\d\.\d\.\d(?=.*broadcast)"` \| pbcopy

	# Less Unix-y, somewhat more readable version
	ifconfig \| ruby -e "print STDIN.read.match(/inet (\d\.\d\.\d\.\d).*broadcast/)[1]" \| pbcopy

	# I use it like this in my .zshrc
	alias ip='echo -n `ifconfig \| grep -Po "(?<=inet )\d\.\d\.\d\.\d(?=.*broadcast)"` \| pbcopy'

	# Methods ending in “=” that accept a single argument will treat multiple arguments as an array.

	class Foo
	def types=(array)
	p array
	end
	end

	foo = Foo.new
	foo.types = [:bar, :baz, :quux] # => [:bar, :baz, :quux]

	<style>
	div {
	width: 0; height: 0;
	border-style: solid;
	margin: 20px;
	}
	div:nth-child(odd) { border-width: 32px } /* edges */
	div:nth-child(even) { border-width: 24px } /* corners */

	.top { border-color: red transparent transparent transparent }

	#!/usr/bin/env ruby
	# encoding: utf-8

	error = `coffee -c #{ENV['TM_FILEPATH']} 2>&1`
	if error == ''
	puts "✔ compiled #{ENV['TM_FILEPATH'].sub(/\.coffee$/, '.js')}"
	else
	puts "❗#{error}"
	end
