The default database for Heroku is PostgreSQL and, while you could use SQLite for development and Postgres for production, there are some inconsistencies between the two. Ideally you would use the same version of the database server but currently Heroku uses version 9 for dedicated databases and 8.3 for shared databases and seem to […]
I realise that OSX does not have a registry to clog up but I have just reinstalled Lion on my Macbook Air; probably a hang up from Windows. This is a checklist for installing Homebrew >> Rails.

The solution is to run the following in terminal: /System/Library/CoreServices/Finder.app/Contents/MacOS/Finder & (don’t forget the &) […]
I’ve decided to use Vim for a few weeks at least and am enjoying it. There are plenty of posts on using Vim as a Ruby IDE and switching from your IDE of choice. Most of the TextMate to Vim posts seem to recommend Janus and for good reason. Janus adds a number of plugins […]
This post is following on from a previous post on Creating the footer. Creating the header was a lot simpler than I thought it would be. The original header in the Roots template is pretty sparse and I want to end up with this:(I’m still unsure about the tag line but it’s not something I […]
