Charles Jolley: “I started working in SproutCore almost 5 years ago because I believe the future of software development lies in native-style apps in the web browser. It is the platform of the future and when that shift change happens, I want to be there with the technology. Now, I believe that time is almost [...]

The Chrome and HTML DevRel team at Google have released a new portal, HTML5 Rocks, that packages together some of the great resources available on HTML5 and the renaissance of browsers.

What does Open Web mean?
What does Ajax mean? Is it AJAX or Ajax?

Mark Pilgrim has a new appendix to his awesome HTML5 book, which collects all of the ways in which you can do feature detection for HTML5.
For example:

<audio>: return !!document.createElement(‘audio’).canPlayType;

<device>: return ‘type’ in document.createElement(‘device’);

Mark Pilgrim continues to create fantastic content for his Dive Into HTML5 book. His latest is on HTML extensibility.
Some folks tried to get us to use RDFa in XHTML (and try to get us doing it in HTML5 too… :/), and we have had the micro-formats folks take a pragmatic approach.
The new microdata work [...]

Paul Irish and Divya Manian have created a fun visualization on readiness of HTML5 and CSS3 standards in various browsers.
It uses a bunch of the usual CSS cool-suspects: -webkit-gradient, -webkit-transition, -webkit-border-radius, and the like (and -moz/-o too).
The added feature is…. do a mouse scroll on the page:
PLAIN TEXT
JAVASCRIPT:

jQuery(document).bind(’DOMMouseScroll mousewheel’, function(e, delta) {

@edr is the man. He did amazing things at Yahoo! and now at his new role at Google he continues in the same vein. This time he has created the coolest set of HTML5 slides ever, using the technology inline.
