      ### Open Source Projects

      This is an incomplete list of projects I've been working on in the recent pasts.
      There are several projects that I've worked on, but long since abandoned because
      they became obsolete and were superseded by other alternatives.

      #### Focal

      Focal is a utility web application that creates sexy and informative burndowns
      for you and your team.

      Hooked up to the Pivotal Tracker API, Focal will gather information about the
      current iteration on a daily basis and provide you and the team with valuable
      progress information.

      _Focal is developed by Kabisa._

      ### IMDB

      The IMDB gem allows you to programatically access IMDB. Although IMDB does not
      officially expose an API you are able to look at what's on their public pages.

      #### Firefly

      At the height of 140 character limited tweets, URL shortners where the hippest
      thing around.

      Firefly provides you with a personal url shortner. It can be easily deployed to
      Heroku and it has proven to be able to handle millions of shortened URLs.

      #### PostcodeAPI

      A simple ruby wrapper around the [Postcode API service](http://www.postcodeapi.nu/).

      #### elfproef

      The 11-check is a checksum algorithm used to validate Dutch bank account numbers and
      social security numbers.

      This gem allows you to add validations to your Rails models for these kind of fields.
