Dealing with Ruby's different versions

To my dismay, Ruby on Rails seems to be linked deeply into OS X's frameworks, which I don't want to mess with. Some poking reveals that the default installation, version 1.8, is in a system framework called Ruby.framework. The normal method to updating such tools is to remove the old version and then install the new one, but I did not want to take the risks this time. Turns out there's a great tool called rvm that will manage multiple Ruby versions!

Complete instructions are here: http://bigdiver.wordpress.com/2011/11/24/update-ruby-and-rails-on-mac-os-x/

They're written with OS X in mind, but adapting them for any Linux system should be trivial.

The Ideal Notebook

If I didn't have my monster of a Hackintosh already.

Presenting the Mac Pro to go, or the retina MacBook Pro. Comes with a built-in 30" screen!

Clearly the first thing I do is run the notebook at native resolution, an incredible 2880x1800. The menu bar nearly disappears, while the dock becomes reasonably-sized. For those incredulous readers, my 20/13 eyesight is sufficient for this resolution. :-)

An 1880px vertical is quite nice for web designing, albeit highly misleading for emulating typical usage.

Day-to-day use. I can fit a bunch of apps onto one virtual desktop, which is how I work on my 30" Dell. It's huge compared to my MacBook Air, which has a 1440x900 screen, and a lot less claustrophobic than my six-year-old MacBook Pro, which has a 1920x1200 screen.
