Rails 3.2 was released on Friday 20 January.  So as any good developer would, I started playing around with it on an app I'm building.It was a breeze getting the bundle updated, just add these lines to the Gemfile and run bundle updateOnce the updated gems had installed, firing up the rails server spat a few errors out.

The subject of mouse movement in OS X has been debated for years now. Personally I despise the default movement settings in OS X and have a whole array of tweaks in place. But that's a debate for another day.Today I'm looking at the new "natural" reversed scrolling feature in Lion.

The Slim template engine seems to have gained a lot of popularity in the Rails community recently. Their site describes it as 'A lightweight templating engine.' For a long time I've loved Haml, taking the approach that I'd rather describe my intent than hard code HTML tags all over the place.However, in hindsight having used Slim for a while it appears Haml might have stepped a bit too far away from HTML, including some cryptic syntax like '%' signs to declare tags.  Slim takes a step back towards HTML.  It still uses the significant whitespace element of Haml and removes the annoying
