Google have updated their HTML5Rocks website with all new content – http://www.html5rocks.com/ While obviously targeted at Chrome developers in particular the site has grown from the demo slideshow presented last year into a useful point of reference now containing samples and tutorials.
Also gaining some traction are sites offering basic HTML5 frameworks such as HTML5 Boilerplate – http://html5boilerplate.com/ – which help ease the development time which stock implementations of basic code. Even with such reference code becoming commonplace web application development still lacks tools to speed up the process. Two that are headed in the right direction though are Glimmer – http://visitmix.com/labs/glimmer/ – a Flash-like jQuery animation builder and 280North’s Atlas – http://280atlas.com/ – which mimics Apple’s Xcode. With an acceleration of support for new web standards we hope there will be an increase in the availability of such tools.
