One of the few problems I have with Janus, the vim settings bundle/plugin/whatever you want to call it, is that whenever I change to the vim window it refreshes the NERDTree. My project has a ton of files in it (like really, a ridiculous amount) so that refresh takes tens of seconds sometimes. Thanks to Tim Tyrrell's (@timtyrrell) tip on twitter after I bitched about it, I found the offending lines in Janus's NERDTree plugin:

#~/.vim/janus/vim/tools/janus/after/plugin/nerdtree.vim
augroup AuNERDTreeCmd
autocmd AuNERDTreeCmd VimEnter * call s:CdIfDirectory(expand("<amatch>"))
autocmd AuNERDTreeCmd FocusGained * call s:UpdateNERDTree()

By adding the following line to your ~/.vimrc.after or ~/.gvimrc.after you can punt on the autocommands from Janus (I don't care about either of them)

:autocmd! AuNERDTreeCmd

Watching Jack Danger's GoGaRuCo presentation the following analogy came to mind.

/lib is the asshole of your Rails application. Its fine (and desirable) for stuff to pass through there. But if you don't poop it out into nicely formed little turds we call gems eventually, your application is going to become constipated. Then you get stomachaches.

Don't constipate your app. Eat lots of roughage.

	Feature: Parsing a stock file
	In order to perform analysis of stock pricing data
	As the importer
	I want to parse a data file

	Scenario: Parsing an AMEX data file
	Given a data file containing:
	"""
	exchange,stock_symbol,date,stock_price_open,stock_price_high,stock_price_low,stock_price_close,stock_volume,stock_price_adj_close
	AMEX,KBE,2010-02-08,22.26,22.45,21.90,21.91,5147800,21.91

	require 'fastercsv'
	class StockParser::Parser
	attr_reader :rows

	def initialize
	@rows=[]
	end

	def import(data)
	@rows = FasterCSV.parse(data, :headers => true)

	unless defined? PhusionPassenger
	module PhusionPassenger

	#the only event I use this with is :starting_worker_process,
	#which takes a `forked` parameter, which we want to be false
	yield false
