It's probably worth noting that ruby 1.8.7 will no longer be supported after June 2013 i.e. there will be no security patches or bugfixes.

True; that said some people moved Rails 2.x apps to Ruby 1.9 (with a bit of patching); I wouldn't be surprised to see LTS migrate to 1.9 gradually.

Pressing tab in insert mode doesn't work for me :(

Only 8GB? ha. I have 4GB and having any kind of flash player open in chrome means I have no RAM free.

Really? Because I have 2GB too and I can have several flash videos open and get along just fine with other programs.

With regards to figure 1 I'd argue that avoiding duplication is far more important than alignment. When I first looked at figure 1 I paused to see if duplicating the case was what was meant or whether each line should match lower case and upper case. To me that signifies less readable code since I've had to re-read it to try to understand it.

For a brief moment there I thought you were suggesting that it should only be available to people who registered 100 or 2 years ago

vim works on mac anyway - macvim for gvim equivalent. As far as I know there aren't any decent tiling wms for mac.

You can use dwm/awesome/wmfs & co under XQuartz, installation and configuration work almost like in Linux.

That said, I use ShiftIt(1), it's free, keyboard based and does EXACTLY what I want it to do.

There are quite a few nice tiling utilities for Mac :)
