What design techniques does Apple use in the introduction page of iPad Air?

Can you mark items on a website as ’unread’ without cookies?
It’s not very exciting, but CSS will let you set different styles for visited vs unvisited links and the technique has worked reliably since the mid 1990s.[... 44 words]

WebKit is Dropping HTML5 “popstate” Events (via) Really nasty bug with WebKit’s pushState support, discovered by Ben Cherry from Twitter. popState events get dropped if the user navigates while an outbound network request is in progress. # 30th October 2010, 7:41 am
Is there any consensus yet on link rel=shorturl vs rev=canonical?
It’s pretty clear from the answers that rev=canonical v.s. rel=canonical is way too confusing—so it’s down to rel=shortlink v.s. rel=shorturl.[... 38 words]
An implausibly illustrated introduction to HTML5 Web Workers. By Mark Pilgrim. # 15th August 2010, 11:14 pm
canto.js: An Improved HTML5 Canvas API (via) Improved is an understatement: canto adds jQuery-style method chaining, the ability to multiple coordinates to e.g. lineTo at once, relative coordinate methods (regular Canvas does everything in terms of absolute coordinates), the ability to use degrees instead of radians, a rounded corner shortcut, a more convenient .revert() method and a simple parser that can understand SVG path expressions! The only catch: it uses getters and setters so won’t work in IE. # 29th July 2010, 9:39 am
I’m renaming the book to “Dive Into HTML 5” for better SEO. This is not a joke. The book is the #5 search result for “HTML5” (no space) but #13 for “HTML 5” (with a space). I get 514 visitors a day searching Google for “HTML5” but only 53 visitors a day searching for “HTML 5”.

Parsing file uploads at 500 mb/s with node.js. Handling file uploads is a real sweet spot for Node.js, especially now it has a high performance Buffer API for dealing with binary chunks of data. Felix Geisendörfer has released a new library called “formidable” which makes receiving file uploads (including HTML5 multiple uploads) easy, and uses some clever algorithmic tricks to dramatically speed up the processing of multipart data. # 2nd June 2010, 3:57 pm
Is This Really The Future of Magazines or Why Didn’t They Just Use HTML 5? A scathing critique of the new Wired iPad app, which weighs in at 500MB per issue due to storing every single page as two static PNG images—one for landscape and one for portrait mode. “The only real differentiation between the Wired application and a multimedia CD-ROM is the delivery mechanism: you download it via the App Store versus buying a CD-ROM”. # 28th May 2010, 12:13 pm

Firefox 4: the HTML5 parser—inline SVG, speed and more. A complete replacement for the oldest part of Gecko (the HTML parser dates back to 1998) headed up by HTML5 validator author Henri Sivonen, using the parsing algorithm defined in the HTML5 specification. Improvements include parsing taking place off the main UI thread and the ability to embed SVG and MathML directly inline in HTML pages. # 12th May 2010, 8:56 am
Paper 5 | Scribd (via) A more impressive example of Scribd’s new HTML/CSS document viewer: a mathematics-heavy LaTeX paper by one of Scribd’s engineers. # 7th May 2010, 12:12 pm
Scribd in HTML5. Outstanding piece of engineering work from Scribd—they can now render documents using HTML, webfonts and a ton of CSS absolute positioning (using ems rather than pixels) instead of Flash. Nothing to do with HTML5 of course, which is rapidly replacing Ajax as the most mis-applied terminology on the Web. That nit-pick feels pretty insignificant compared to their overall achievement though—being able to convert any formatted document (.doc, pdf etc) in to HTML and CSS that displays correctly is a real leap forward. # 7th May 2010, 12:09 pm
Pure CSS3 Spiderman Cartoon w/ jQuery and HTML5. Great demo, though calling -webkit-animation HTML5 (or even CSS3) is a bit of a stretch... # 4th May 2010, 7:27 pm
Blowing up HTML5 video and mapping it into 3D space. The canvas drawImage() method can take an HTML video element as its source, making all kinds of interesting effects possible. The author notes that performance was dramatically improved by copying the video frame in to a separate canvas element and then copying regions out of that element rather than grabbing regions from the video directly. # 21st April 2010, 9:30 am

The Widening HTML5 Chasm. Simon St. Laurent’s commentary on the HTML5/Adobe situation. The most interesting piece I’ve read on it so far. # 15th February 2010, 9:51 pm
No part of HTML5 is, or was ever, “blocked” in the W3C HTML Working Group -- not HTML5, not Canvas 2D Graphics, not Microdata, not Video -- not by me, not by Adobe. Neither Adobe nor I oppose, are fighting, are trying to stop, slow down, hinder, oppose, or harm HTML5, Canvas 2D Graphics, Microdata, video in HTML, or any of the other significant features in HTML5. Claims otherwise are false. Any other disclaimers needed?
— Larry Masinter # 15th February 2010, 9:31 pm
At this point all I could honestly tell you from the point of view of the editor of several of the HTML5 documents being held up is that the W3C have said they’re won’t publish without the objections being resolved, and that the objection is from Adobe. I can’t even tell what I could do to resolve the objection. It seems to be entirely a process-based objection.
