Get Homebrew installed on your mac if you don't already have it

Install highlight. "brew install highlight". (This brings down Lua and Boost as well)

Thoughts on Swift 2 Errors

When Swift was first announced, I was gratified to see that one of the (few) philosophies that it shared with Objective-C was that exceptions should not be used for control flow, only for highlighting fatal programming errors at development time.

So it came as a surprise to me when Swift 2 brought (What appeared to be) traditional exception handling to the language.

Similarly surprised were the functional Swift programmers, who had put their faith in the Haskell-style approach to error handling, where every function returns an enum (or monad, if you like) containing either a valid result or an error. This seemed like a natural fit for Swift, so why did Apple instead opt for a solution originally designed for clumsy imperative languages?

I'm going to cover three things in this post:

	#!/bin/bash
	#
	# Build a virtual environment suitable for running appengine.
	# This uses virtualenvwrapper to make the virtual environment.
	# Which you can activate with 'workon appengine'
	#
	# Everyone loves one-liners!
	# Mac one-liner:
	# $ curl -s https://raw.github.com/gist/3021613 \| bash
	#

	#!/bin/bash

	while :
	do
	clear
	git --no-pager log --graph --pretty=oneline --abbrev-commit --decorate --all $*
	sleep 1
	done
