Newspaper Club—A work in progress. “We’re building a service to help people make their own newspapers. This is the blog where we’re alarmingly honest about where it’s all going wrong.” # 7:34 pm

Video for Everybody! Reminiscent of the early days of Web Standards, Kroc Camen has created a fiendishly clever chunk of HTML which can play a video on any browser, starting with HTML5 video then falling back on Flash and eventually just an HTML message telling the user where they can download the file. No JavaScript to be seen, but conditional comments abound. Requires you to encode as both Ogg and H.264, but Kroc includes details instructions for doing that using Handbrake. # 7:33 pm

Modernizr (via) Neat idea and an unobtrusive implementation: a JavaScript library that runs feature tests for various HTML5 features (canvas, box shadow, CSS transforms and so on) and adds classes to the HTML body element, allowing you to write CSS selectors that only apply if a feature is present. Detected features are exposed to JavaScript as boolean properties, e.g. Modernizer.multiplebgs. # 10:56 am

Codecs for <audio> and <video>. HTML 5 will not be requiring support for specific audio and video codecs—Ian Hickson explains why, in great detail. Short version: Apple won’t implement Theora due to lack of hardware support and an “uncertain patent landscape”, while open source browsers (Chromium and Mozilla) can’t support H.264 due to the cost of the licenses. # 10:16 am
