OBSOLETE

This entire guide is based on an old version of Homebrew/Node and no longer applies. It was only ever intended to fix a specific error message which has since been fixed. I've kept it here for historical purposes, but it should no longer be used. Homebrew maintainers have fixed things and the options mentioned don't exist and won't work.

I still believe it is better to manually install npm separately since having a generic package manager maintain another package manager is a bad idea, but the instructions below don't explain how to do that.

Fixing npm On Mac OS X for Homebrew Users

Installing node through Homebrew can cause problems with npm for globally installed packages. To fix it quickly, use the solution below. An explanation is also included at the end of this document.

Pragmatic Paranoia

This chapter is about defensive coding practices, both against users of your software and against yourself. Pragmatic Programmers, after all, understand that everyone makes mistakes, even themselves.

Design by Contract

This confused the shit out of me. I wasn't entirely sure what the difference was between a contract and a unit test.

Contracts are introduced in the context of employment contracts. That is, before any work is done, the responsibilities of both parties are defined, as well as the consequences of failing. Contracts in programming are similar. As I mentioned before, I wasn't able to make a strong distinction between contracts and unit tests (given some condition, when some event, then this should happen, though I may be confusing this with [BDD][bdd]). It's all a bit jumbled in my head.

Ubuntu 12.04 Ruby on Rails Development Environment

I haven't set up an install guide for the latest ubuntu release, largely because the last set of instructions worked pretty closely with the latest and greatest Ubuntu, 12.04 Precise Pangolin, however when installing today, I found that there were enough differences in the way that I configure my setup to justify an update, so here it goes. Yes, I'm late to the party, but a quick google search didn't find anything that I felt was as complete for my requirements as my previous install guides, so here I go.

As always with my install guides, I have included here is just about everything you'll need (and then some) to get started with ruby on rails development with Ubuntu 12.04 as a platform. These are my settings and preferences, and this is certainly not the only way of doing things, so keep that in mind.

Step 1: Get the repos ready and run updates.

sudo apt-get update && sudo apt-get upgrade
