We've always put a heavy emphasis on performance at Stack Overflow and Stack Exchange. Not just because we're performance wonks (guilty!), but because we think speed is a competitive advantage. There's plenty of experimental data proving that the slower your website loads and displays, the less people will use it.[Google found that] the page with 10 results took 0.4 seconds to generate. The page with 30 results took 0.9 seconds. Half a second delay caused a 20% drop in traffic. Half a second delay killed user satisfaction.In A/B tests, [Amazon] tried delaying the page in increments of 100 mill...

HTML5 is generating all kinds of buzz these days. Some of the buzz is about HTML5 being a replacement for Adobe’s Flash. I don’t think it’s there yet but it’s certainly on the way to changing the way content is presented on the web. This is a description of a very simple animation in an HTML5 canvas element. It is coded for readability and not for optimized operation.We’ll add a canvas element to a web page and then use javascript to draw on it. We will redraw it all every 10 milliseconds with minor changes to create the magical illusion of animation. Using j...

You’ve probably been hearing a lot lately about how Flash is a dying technology and how it’ll soon be replaced by HTML5. Personally, I think that it will slowly replace Flash for some things, but Flash will always have a place, especially for developing complex games and rich internet applications. If you’ve yet to see what HTML5 can do, I’ve rounded up 10 demos that show off some of its capabilities.So what do you think – will HTML5 replace Flash?Canvas Minimal Particle AnimationCanvasMolFlickr and Canvas in 3DCloth SimulationetchaPhysicsGoogle Images Gift B...

A comparison of streaming video via the Adobe Flash and HTML5 formats with numerous different browsers on both Mac and Windows produced wildly different results based on the operating system and browser, making neither a clear winner.The test, from Streaming Learning Center, was conducted in response to recent comments alleged to have been said by Apple co-founder Steve Jobs, in which he reportedly called Flash a "CPU hog." While the test found that HTML5 is significantly more efficient than Flash on the Mac when running the Safari Web browser, those same advantages do not exist on other Mac b...

In the past two years, increased browser support has transformed CSS3 from a fringe activity for Safari geeks to a viable option for enterprise level websites.While cross-browser support is often too weak for CSS3 to hold up a site’s main design, front-end developers commonly look to CSS3 solutions for progressive enhancement in their sites. For instance, a developer might add a drop-shadow in Firefox, Safari and Chrome using -moz-box-shadow and -webkit-box-shadow, and then be comfortable with this design enhancement falling off for IE users.But wouldn’t it be great if...
