Yesterday, Yahoo! launched two brand new libraries for Design Patterns and User Interfaces. The Design Pattern libary describes some elegant solutions to common design and UI problems for web applications, and the User Interface library consists of freely downloadable JavaScript utilities and snippets for building rich web-apps. Lots of cool, AJAX-y goodness in there.

As some of you might know, Yahoo is powered primarily by FreeBSD servers, so it's nice to see that the UI library components have been released under the BSD license.

When I get some time, I'm going to have to take a look and see if there are any libraries that I could make use of on this blog or any of my other web dev projects.

At the same time, Yahoo also launched a new User Interface blog, and there are already a number of interesting posts about various design patterns. Subscribed!
