JXT - Javascript XHTML Tags

By Davide Zanotti
October 12, 2009

First of all, I would like to thanks Rich Tretola and O'Reilly, for the possibility to write on this blog and talking about my project (http://www.jxtproject.com), I'm very thankful for that! ...and I'm quite embarrassed, because this is my...

jQuery and AIR - Moving from web page to application (2)

By Raymond Camden
October 1, 2009

Earlier this week I blogged about a new jQuery based AIR project, Hangman. In the first blog entry I talked about the game and the jQuery code behind it. One of the main problems with the code in that entry though is that it really isn't an AIR application. I mean sure it makes use of the AIR framework. Sure it's an AIR application technically. But none of the code actually did anything - well, AIR like! We can fix that don't you think? As a followup I discuss modifying my Hangman game to make use of a database of words.

Welcome To The Dojo

By John Barlow
September 29, 2009

The Dojo Javascript Framework is truly awesome. I'll admit, the documentation is a bit to dig through, but hopefully my experience and previous digging will be of use to you. Don't worry, the only things being thrown around in this "Dojo" are Javascript and web programming ideas you may or may not have seen before. In this article I would like to accomplish two major things: giving an introduction to the Dojo Javascript Framework and a walk-through of how I approach creating a RIA using dynamic HTML and Dojo.

HTML 5 comics

By Rick Jelliffe
September 11, 2009

CSS quirrel is an online comic that is good for a few laughs. You can tell it would be funny if you knew what on earth they all were talking about. Actually, most of the comics are really paired with blog items giving the back story. It is a really cute format. Read on for a few of my favorites.

Do we need lazy loading XML parsers to make XHTML scalable?

By Rick Jelliffe
September 10, 2009

The W3C Systeam's blog has a hilarious item W3C's Excessive DTD Traffic. Apparently, generic XML systems are trying to download the DTD using the DOCTYPE declaration system identifier (i.e. what it is for) on XHTML files, or downloading the schemas from the namespace URI (i.e. not what it is for) for documents with XHTML fragments. And it is a lot of bogus traffic. W3C does not want to cop having to serve dumb XHTML requests for DTDs and schemas. A different DOCTYPE and a lazy loading parser policy would help. But I think all the ISO/MathML special character public entity sets should be built into XML.

Jotting on parsers for SGML-family document languages: SGML, HTML, XML #3 - Putting it together more

By Rick Jelliffe
September 8, 2009

Now by now you may be saying Rick, are you really saying that SGML can only be described by some kind of seven-level grammar? Zut alors! And HTML and XML too?

Jotting on parsers for SGML-family document languages: SGML, HTML, XML #2 - Stateless semicoroutines may be convenient

By Rick Jelliffe
September 8, 2009

Here is Melvin Conway's foundation point from his 1963 paper defining coroutines: "That property of the design which makes it amenable to many segment configurations is its separability."

Weak validation using hash codes

High performance gateways are a potential use case for efficient weak validation systems.

Jotting on parsers for SGML-family document languages: SGML, HTML, XML #4 - Some links to research

By Rick Jelliffe
September 8, 2009

We seem to be getting to the stage of finally having several credible candidates for language class that can cope with SGML-family systems.

Jotting on parsers for SGML-family document languages: SGML, HTML, XML - You say automata and I say automata

By Rick Jelliffe
September 2, 2009

But it is no use me sitting here complaining that people are saying "drop SGML" without even knowing what it is they are dropping. So I thought I'd make some little diagrams roughly scoping a basic machine for SGML family parsers.

Why is HTML Suddenly Interesting?

By Simon St. Laurent
August 27, 2009

After a decade of quiet, HTML is a hot topic once again. While there is pent-up demand for new features, the conversation reflects a more basic change in the Web's landscape.

Let's Call It A Draw(ing Surface) - Diving Into HTML 5

By Mark Pilgrim
August 18, 2009

This excerpt is from "Dive Into HTML 5" which will be published in early 2010 by O'Reilly Media. The book will cover features from the upcoming HTML 5 specification and other emerging standards. HTML 5 is still a work-in-progress; browser support is listed at the beginning of each section.

Flex's coopetition: HTML5

By Mike Slinn
August 14, 2009

It won't be ready for prime time this year, and probably not next year, but the HTML5 specification is firming up and current implementations suggest a that HTML5 will be a strong platform for RIAs. People familiar with other versions of HTML might assume that Flex would have a few advantages over HTML5: AIR (no browser required) and data services (distributed computing.) The neologism 'coopetition' might be an apt term for the relationship between HTML5 and Flex.

Yes, you can now use quite a bit of SVG in the Internet Explorer too. With Ample SDK.

By Sergey Ilinsky
July 31, 2009

The Scalable Vector Graphics technology, SVG in short, seems to be experiencing nowadays its second (or third?) birth on the web. The browser vendors are investing heavily into lifting up what they initially prototyped long time before. This is true of Opera, Firefox, Safari and Chrome, but there is no clear indication on the plans to supporting SVG from the major browser vendor - Microsoft. True, Microsoft has recently made a vague statement on its commitment to support the standards and the thrilling web-as-a-platform thing aka HTML5, but in what extent and when? And what shall we do until that time has come, or until the older IE browser park has updated?

Google's Unique Position and Imperative Need for Browser Interactivity

By Timothy M. O'Brien
May 28, 2009

Google's clarion call for HTML 5 and rich interactive browser applications marks an interesting fork in the road for technologists. Will we invest our time in learning more proprietary, native APIs to create better iPhone and Adobe AIR applications, or will everything start to move toward a standards-based browser as the underlying platform for interactivity. Despite Google's influence in the market, this isn't a foregone conclusion. Just how long will it take for the content generators to adopt HTML 5? And, what's in it for Google?

Google Bets Big on HTML 5: News from Google I/O

By Tim O'Reilly
May 27, 2009

"Never underestimate the web," says Google VP of Engineering Vic Gundotra in his keynote at Google I/O this morning. He goes on to tell the story of a meeting he remembers when he was VP of Platform Evangelism at Microsoft five years ago. "We believed that web apps would never rival desktop apps. There was this small company called Keyhole,...

The Assertions in HTML 5 - What kinds of constraints are assertions used for in HTML5? What about the content models?

By Rick Jelliffe
May 19, 2009

Lets look at the assertions in draft of HTML 5: The Markup Language which collects constraints about the markup: the kinds of things that are susceptible for schema testing.

The Bold and the Beautiful: two new drafts for HTML 5

By Rick Jelliffe
May 12, 2009

Two new drafts out at W3C from the HTML 5 effort: HTML 5: The Markup Language and HTML 5: A vocabulary and associated APIs for HTML and XHTML. The first one is a model of the kinds of standards-writing we need. The second one is much larger, and is where many of the fiddles of historical HTML applications go.

Excellent result for @charset detection of CSS in WWW browsers

By Rick Jelliffe
September 16, 2008

So, from these test results, it looks pretty good for adopting the same policy for determining the encoding for CSS files as you use for XML: if there is a BOM then use that (i.e. your document is in UTF-16 of some kind); otherwise use explicit labeling with an initial @charset.That works with all the current generation, which is really great.

Cross-platform APIs to be in the WWW driver's seat next?

By Rick Jelliffe
September 16, 2008

The alternative to HTML 5 is for websites based on cross-platform APIs: not just browser sniffing but platform sniffing. ...As well as seeing HTML 5 as a way to ward off the evils of proprietary formats, we need to figure out how to use it to neutralize the negative impacts of these formats: if HTML 5 and CSS can be augmented in ways that take advantage of slicker rendering and interaction by the specific-vendor platforms, then their presence becomes a net gain not a challenge to interoperability.

HTML4ever or: the next logical step

By Michael Hausenblas

These days, it seems it's in vogue to rant about HTML 5. I'd rather explain the need for structured XHTML.
