Using Git Submodules for Shared Rails Components

In some cases you may have the need to run multiple Rails applications with shared functionality. While Rails 3 promises to bring “mounting apps in apps” and the ability to make the whole process simple, for now we’re stuck in the real world. However, it is possible to share components. This post will walk you through how to set up shared components that live in multiple Rails applications at once and even run specs properly.

Google has a weather api that is dead simple to use. Just discovered that tonight so I whipped together a wrapper using HTTParty.

If you have to reply with “You go to z and press n and press submit,” then you are going to have problems.

Playing on a Grid

For my dissertation I'm working on a genetic algorithm solution to the guitar fingering problem. It's got just under 2 months to run now, and it's time to start wrapping it up.

Part of the process is getting results and evaluating them. I have running code now so it's time to start putting it through its paces.
