There is a lot of chatter about the improvements HTML5 is about to unleash on the web development world. How will this new standard affect web dev frameworks like Faces, Struts, or even ASP.NET? How long will it take them to 'catch up' in order to emit such code? Will controls get deprecated? ...

Here's a webpage that does what I'm describing: http://mashable.com/2010/05/13/mobile-tech-journalists/ What's going on with the images?

I'm coding an app (temporarily up here), and I want to make its parameters modifiable. I feel the best way to do this would be with your standard GUI slider elements (a la this, but not so ugly). I just noticed that the DOM doesn't provide these, however... What's the best way to introduce sliders to a webpage? Is there a standard libr...

I tried this sample here: http://9elements.com/io/projects/html5/canvas/ After a few minutes, Firefox slows down so much I can't even popup any menu. When I closed the tab, Firefox comes back to normal again. So is HTML 5 really a good choice now ? ...

This month's Playboy came with a pair of 3D glasses (red/cyan) to view the eye-popping centerfold. Naturally, I hit the Internets to find every single red/cya...

I was about to redo a Rails site today using AJAX so that the background could remain in place. Then I thought, "that would be exactly like using frames," and then I thought about SEO consequences and I dropped the idea entirely and took a look around the Web.
