Professional Python Frameworks: Web 2.0 Programming with Django and Turbogears. Apparently published by Wrox in October 2007, beating the “official” Django book by just over a month. Has anyone seen this on bookshelves yet? # 9:16 pm

JavaScript Beautifier (via) Useful online tool (source code also available) for un-obfuscating JavaScript that has had its whitespace stripped out. # 8:43 pm

Yahoo! Search Contextual Precaching. Neat performance trick on Yahoo! Search: the moment you start typing (indicating you intend to search) the site quietly fires off a bunch of requests to precache assets needed for the search results page. # 3:58 pm

Taking the canvas to another dimension. Opera have finally released a test version with support for a opera-3d canvas context—Windows only for the moment, but Mac and Linux versions are promised “soon”. # 1:39 pm

I don’t understand why the NSA was so insistent about including Dual_EC_DRBG in the standard. It makes no sense as a trap door: It’s public, and rather obvious. It makes no sense from an engineering perspective: It’s too slow for anyone to willingly use it. And it makes no sense from a backwards-compatibility perspective: Swapping one random-number generator for another is easy.

CSS3 and the death of Handheld Stylesheets. I hadn’t looked at CSS 3 media queries before (which let you apply different styles based on media features such as screen width, height and colour availability)—they seem like a much smarter solution that handheld stylesheets and also appear to be preferred by device vendors. # 9:53 am

Ten New Things in WebKit 3. Does “incremental updates for persistent server connections” for XMLHttpRequest mean Safari now has native support for Comet? # 1:19 am
