Popular podcaster Scott Hanselman delivers a humorous talk describing how the basic features of an operating system exist in both the cloud and the browser.
My rating: 3/5. Entertaining for programmers, though light on technical take-aways.
"The Humble Border-Radius"
In this talk Lea Verou demonstrates how border radii can be used to create a variety of shapes and animations, as well as upcoming CSS specifications for different corner shapes. While interesting, I think what web designers really want is complete flexibility to design arbitrary shapes, and border-radius seems like a very awkward mechanism for accomplishing that.
My rating: 3/5. Interesting CSS hacks.
