steveklabnik / maze.rb

Created December 5, 2011 00:30

For posterity

	# This code solves one of Mike Amundsen's maze+xml mazes: http://amundsen.com/media-types/maze/
	#
	# The code isn't great. I just wanted to see how easy it'd be. So I built up a little test, extracted
	# some stuff into a method... next thing you know I've got a little procedural application.
	#
	# Backtracking implementation borrowed from https://github.com/caelum/restfulie/blob/master/full-examples/mikemaze/maze_basic.rb because I'm lazy.

Wtf cancan?

	# Article is a normal AR class, no methods, just attributes. free is a boolean attribute.
	#
	# /articles/1 is free, /articles/2 is not.
	#
	# I want only logged in users to read non-free articles. But the :free => true line seems to be enabling
	# reading all of them; when I comment it out, non-logged-in users can't read anything. But with it
	# uncommented, they can read everything. WTF?
	#
	# User.new.is? :user is false, and so is User.new.is? :admin.

steveklabnik / shallow-vs-deep.html

Created December 14, 2011 21:29 — forked from jonm/shallow-vs-deep.html

Shallow vs. deep representations in XHTML Hypermedia APIs

	<html>
	<body>
	<!-- the following div is a sample representation of a 'car' domain object; it can be identified as
	such by the presence of 'car' in its @class. In this case, the car has two attributes, a make
	and a model, and both are included right here. This is what I call a deep/complete/concrete
	representation. -->
	<div id="car123" class="car">
	<span class="make">Ford</span>
	<span class="model">Mustang</span>
	</div>

steveklabnik / total_bullshit.rb

Created December 27, 2011 03:52

This is some random bullshit about non-nullable stuff in Ruby.

	# I'm making all this up. Just random thoughts. It's 11pm, this probably wouldn't even work.

	class Object

	@nullable = false

	def nullable?
	@nullable

steveklabnik / regexp.rb

Created January 9, 2012 18:40

I think this spec implies that I should commit myself into some kind of rehab.

	it "lists them in reverse chronological order" do
	recent_titles = Article.for_dashboard.map(&:title).map{\|t\| Regexp.quote(t) }
	title_regex = Regexp.new(recent_titles.join(".*?"), Regexp::MULTILINE)
	page.html.should match(title_regex)
	end
