Want to get started developing sites and web applications that run on all modern browsers, including the upcoming Internet Explorer 9? You’ll need HTML 5 (along with CSS 3 and JavaScript) and a handy guide like Mark Pilgrim’s new book, HTML5 Up and Running.
Today and today only (Friday, August 20, 2010), you can get the ebook version (PDF, ePub and mobi) of HTML5 Up and Running for just USD$9.99 (it normally goes for USD$23.99). Just go to the HTML5 Up and Running page in the O’Reilly site, order the ebook and use the discount code DDHUR when you check out!
…plus how IE9 PP4 stacks up against its previous incarnations and browsers built by the Esteemed Competition, according to the WebKit SunSpider JavaScript Benchmark test…
…and that there are a new batch of demos showing HTML5 compliance, hardware graphics acceleration, JavaScript speed and the really wacky things you can do with IE9 if you use a little imagination, such as a game that melds “Hamster Dance” with Dance Dance Revolution:
Go Get IE9 Platform Preview 4, Get Ready for the Beta
As you take this version for IE9 for a spin, you might want to start thinking about getting your sites, whether they’re already up or in the works, ready for the next big leap: IE9’s transition from “Platform Preview” to “Beta”. That’s coming soon.
Test your site in IE9 Standards Mode. This mode provides the best performance and interoperability and will offer additional benefits in the IE9 Beta. We suggest using the HTML5 doctype. More details here and here.
We recommend sending IE9 the same standards-based markup your site sends other browsers. More details here and here. From the feedback so far, and our experience with sites, the best way to get your site working in IE9 Standards Mode is to start from the same markup other browsers receive rather than IE6, IE7, or IE8 markup.
Use featuredetection, not browser detection to handle any cross browser differences in behavior or feature support. This keeps your site working even as browsers change.
Please continue to report issues on Connect if your site doesn’t look or work right, and you’re giving it the same code as you’re giving to other modern browsers. With IE9 Platform Preview 4, we’ve fixed over 100 community-reported issues. We will fix even more between now and the IE9 beta and want your feedback.
Consider the experience for IE9 Beta users if you find that sending the same markup creates more issues than you can resolve in your production site. It is possible that running your site in Compatibility View is better for your users.
Take advantage of HTML5, CSS3, SVG, DOM, ES5, and more… all described here in the developer guide. We’re excited to run the amazing experiences you bring to the web using these new capabilities, taking advantage of hardware through IE9.
Before there were Microsoft blogs (such as Canadian Developer Connection), there was Channel 9, Microsoft’s community site run by Microsoft employees. Like Microsoft blogs, Channel 9 gives you unfiltered access to the people building stuff at The Empire, all outside the control of the marketing and PR departments. Channel 9 features a lot of videos – there are times when they post several videos in a day – featuring developer news and training, training kits and courses, discussion forums and wikis for various Microsoft tools and technologies. If you’re a .NET developer or just curious about what’s going on the in the .NET world, you should check out Channel 9 and see what’s happening.
Channel 9 posted a number of videos covering the new features in the third Platform Preview of Internet Explorer 9. I’ve gathered them all into this blog article – enjoy!
The IE9 team showed a preview of support for the <video> tag, and with Platform Preview 3, you can try it out for yourself. In this video, you see how it’s used to build the IMDb Video Panorama demo.
There are lots of boring ways to show of ECMAScript 5’s new array methods in action, but why not show them off with a fun game? In addition to the new JavaScript goodies, the ECMAScript 5 Game demo also shows off:
Earlier this week, I was asked to make a short video that would be shown during a round table discussion on a hot topic: HTML5 vs. proprietary rich internet app technologies, such as Flash and Silverlight. My video was supposed to take the “RIAs complement HTML” side of the debate, while someone else would produce a video taking the “HTML5 trumps RIAs” side.
My own personal belief is that HTML5 – actually the stack of HTML5, CSS3 and Java/ECMAScript – has closed the interactivity gap between the web and desktop apps and will continue to close it. However, for the time being, there are still cases where HTML5 just can’t cut it – for various reasons, such as performance, browser compatibility or designer-friendliness – and that’s where RIAs shine. Hence I found it rather easy to put together an amusing little video titled HTML5 and RIAs: Friends with Benefits (5:47, YouTube).
I did the production work on Tuesday afternoon and evening using the following tools:
