Previous versions used homebrew to install the various versions. As suggested in the comments, it's better to use pyenv instead. If you are looking for the previous version of this document, see the revision history.

$ brew update
$ brew install pyenv
$ pyenv install 3.5.0
$ pyenv install 3.4.3
$ pyenv install 3.3.6
$ pyenv install 3.2.6
$ pyenv install 2.7.10

$ pyenv install 2.6.9

..or how I made my own heroku in a few hours for $3.98.

This write-up is several years out of date! You probably shouldn't use it.

So you can be an op, you need to register, you can do that by running this command:

/msg nickserv register your_password your_email_address

To become an operator on #arlingtonruby:

/msg chanserv op #arlingtonruby

To make someone an op:

Draft for Arlington Ruby. Adapted from Tampa Ruby. And by "adapted," I mean "stolen."

tl;dr - CoderNight is to practice development. You write code in pairs or individually and submit the code to me. I post an anonymized repo and you have a week to look at all the solutions before a friendly night of code review.

NOTE: Please email me or ask in the IRC channel: #arlingtonruby on freenode if you have questions.

Bearded's Hourly Contract

Date: [[Date of Document]] Between [Our Company] and [Your Company]

Summary

We’re not big on formality, but sometimes it’s best to have a few simple things written down so that we’re all on the same page. In this contract you won’t find complicated legal terms or large passages of unreadable text. We have no desire to trick you into signing something that you might later regret. We do want what’s best for the safety of both parties, now and in the future.

	# This is a programming chellenge from David Bock's series
	# "What Computer Scientists Know". This is a problem that can
	# be used to discuss a bunch of computer science topics, but
	# as I'm providing most of the skeleton of the solution, the
	# point of this exercise is to demonstrate 'recursive backtracking'.

	# this problem is based on the classic 'triange peg game', a common
