On the Interwebs, number 8

Some websites I have found interesting (in no particular order):

Font Squirrel — Very cool website listing quality fonts that can be downloaded and used on a web page using @font-face.

Arduino — As I understand it, a way to build your own electronics. Now all I need is an idea!

Internet Explorer 8 - Browser for the Better — Upgrade your browser and Microsoft will feed hungry people!

World’s First Grocery API — More businesses/stores need to do stuff like this.

iPhone Sudoku Grab: How does it all work? — Very clear explanation of the computer vision techniques used to read in a Sudoku from an image.

UUID as your ActiveRecord primary key and default_value_for Rails plugin — How to get ActiveRecord to use UUIDs are primary keys. If you are doing anything distributed, UUIDs are the way to go!
