Always keep your eye on the goal: if Donald Knuth didn't say that, he might as well have. So while you may know a lot of specific features of HTML5, it's always important to keep in mind the basic design principles that guide the W3C and WHATWG. There's an official document for that, but it's pretty long. Check it out for full discussion. But if you don't have time, this article contains the gist.

It is possible to get access to the individual pixels of an HTML5 canvas. You do so using an ImageData object. The ImageData object contains an array of pixels. By accessing this array you can manipulate the pixels. When you are done with the pixel manipulation, you need to copy the pixels onto a canvas to display them. This article shows you how to do all of these things.

Traditional content management has been very monolithic, meaning that by choosing a particular editing interface, CMS users also have to take the web framework, programming language and content storage mechanism mandated by the developers of their system. By splitting the CMS to the separate concepts of user interface, web framework, and content repository we can provide implementers a greater degree of freedom, and allow CMS developers to focus on the functionality where they can best make a difference.

A year ago, I’ve reviewed the BlackBerry Browser for PlayBook –the tablet from RIM- as the browser with better support on new HTML5 APIs (see 1.0 review). Yesterday, 2.0 version of the operating system was released for free for every user and I’ve just investigated the new APIs available. Let’s see what I’ve found.

For my upcoming book on Backbone.js and CoffeeScript, I am working on a subtle approach to interactivity that does not disrupt the flow of normal reading. Most readers say that they do not even notice at first that the code listings are embedded CoffeeScript editors. Please let me know what you think. Does interactivity in HTML books outweigh the disadvantages of reading in a browser? Any thoughts about executable JavaScript in PDF or other digital formats?

One of my favorite new features in ColdFusion 10 is the powerful web socket support. Simply put, it is a simple way to create a two way connection between multiple clients (browsers) and your server. Like most things, ColdFusion makes using web sockets incredibly easy. Let's look at a few demos.

For useful and fast complex queries, however, up-to-date indexes are necessary. In this post, Gil Fink explains how to use the updateneeded event to update an existing objectStore with a new index.

In the not-too-distant future, many capabilities that were exclusive to plugin-based content will be accessible to the HTML/JavaScript world without any plugin dependencies. This includes access to media devices (microphone and camera), as well as real time communications. You might be reading this thinking “no way, that is still years off”, but it’s not.

Earlier this month a post appeared on the whatwg discussion list, proposing a pie-in-the-sky-ish modification to (presumably HTTP, or maybe SPDY) standards: 'let browsers report device capabilities in a request header'. The proposal touched off a huge, passionate discussion, whose end result was: the new W3C Responsive Images Community Group.
