Looks like the Yahoo! Developer Network is offering a plethora of resources for developers. First off is a UI Library, which focuses on building interactive web applications utilizing DOM Scripting, HTML and AJAX through a set of controls written in Javascript. The second offering is the Design Pattern Library, which deals with functionality you can add to web applications or projects with things such as auto-complete, drag and drop components and breadcrumb navigation. There is more in the developer area, but its nice to see Yahoo! offering some of their hard work to the community free of charge. (via Slashdot)
