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.

IndexedDB, the 'HTML5' API for advanced key-value data management, is designed to handle much more sophisticated queries than e.g. Web Storage. 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.

Site navigation with an accordion widget? Yes, it's efficient, and jQuery can do it easily; but can you do it with CSS3 alone? Yes, of course; and here's how, with full code.

Isolated testing lets you quickly find and correct particular problems, but does a poor job locating site-wide and integration errors. For end-to-end functionality testing, Zombie.js makes quick checks easy -- and, besides, lets Daniel Mohl use his very own ExpectThat project, a CoffeeScript library for writing expressive, self-documenting unit tests. In this post Daniel explains exactly how to use ExpectThat with Zombie.js, with a simple code example.

With regards to visual information from sporting events, Luis Sobrecueva realized something cool: most games are played on a grass surface; so items moving on the surface (ball, people) can be detected as less-green fields. So he tossed together a cool Canvas with some sweet JavaScript that looks for the ungreen, and stitches the ungreen together...

Recently I discovered the annotated and hyperlinked ES5 refererence, which is pretty cool in itself. But it's still massive enough that a dynamic interface would improve readability considerably, and a new project to dynam-ify the document might take a big step in that direction. Meanwhile, Chrome just made some new ECMAScript features available in its dev channel, which anyone interested in ECMAScript.next might want to check out.

There's a great video on YouTube detailing an Easter Egg in the score for the movie Inception. Basically Inception is about dreams and the slowing down of time. Likewise the score is based on the slowing down of music that is played inside the plot of the movie. Pretty cool. But Terence Ryan added even more cool by using this concept to show off the Audio capabilities in HTML5.

Robert Nyman shares his thoughts on the CSS vendor prefixing problem and possible solutions. First, blaming one group in particular (developers, CSS WG, browser manufacturers) makes little sense -- and in any case the blame game is never very productive. Second, there are two possible solutions: evangelizing web developers, to make sure they use all vendor prefixes in their code (not just -webkit); or implementing the -webkit prefix in every browser, at least for a few prominently used features.
