The YUI team has put out YUI 3.0:
We’re pleased to announce today the general-availability release of YUI 3.0.0. YUI 3’s core infrastructure (YUI, Node and Event) and its utility suite (including Animation, IO, Drag & Drop and more) are all considered production-ready with today’s release.
This is a ground-up redesign of YUI:

Elias Klughammer has implemented the Juggernaut push server in a Cappuccino app.
Always nice to have an open source bare bones sample app for a marriage like this. Nothing beats looking at the source.

Dear Ajaxian Community,
As editors-in-chief so to speak, I always feel that it is important to fully disclose to the community any affiliation change. We have always tried to by balanced, and show that by featuring all kinds of news (for example, we haven’t been shy at posting about great WebKit tech while at Mozilla, or [...]

We usually post these on Friday, but who says a little fun on Monday is wrong? Paul Brunt has put together a nifty game using the Canvas tag. It’s pretty impressive. He is also using Chrome Frame to have the game work on IE as well.

Inspired by its conceptual simplicity, Andrea Giammarchi ( cough, the newest Ajaxian, cough ) has revisited an old ActionScript 1.0 Image effect making it lightweight, 1.2Kb minified and gzipped, and portable, thanks to its cross-browser nature and zero libraries dependencies.
