Using Google Analytics With AJAX

By John Barlow
November 19, 2009

A couple months ago I wrote an article on how to use Dojo to create a rich UI for websites. One of the key points of the article was how to support all users -- those with JavaScript enabled and those without. The purpose of this was to enable basic browsers like search engine spiders to go through your site without JavaScript, while enabling the rich interface for your regular users.

Building a "Slide Gallery" Demo in Apache Pivot

Web Video Hack: Many Movies, One Player

Here's a super-easy way to play multiple movies in the same area on a webpage. No JavaScript required, and it works on iPhone too.

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

By Sergey Ilinsky
July 30, 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?

Using Ajax and Search Referrer Info to Help Users Navigate Your Site

By Kyle Dent
July 22, 2009

Using the referrer URL to detect what brought users to your site can let you help them find what they're looking for. The almost magical asynchronicity of Ajax lets you provide additional content for users from search engines. It requires only minor changes to your site and doesn't affect the experience for others.

Are we losing the Declarative Web?

By Philip Fennell
March 31, 2009

I saw something the other day that I was both intrigued and bothered by in equal measure. 'Mozilla and the Khronos Group Announce Initiative to Bring Accelerated 3D to the Web'. Apparently, the working group will look at exposing OpenGL capabilities within ECMAScript. The intriguing part is that, as a fan of 3D Computer Graphics and Animation this has got to be a good sign, especially if it is exposed in this way; but the bothersome bit is how people will end up using it because it has been exposed in this way. The crux of the problem for me is the question, JavaScript - what's it good for? Absolutely...

PhoneGap: my new favorite open-source project

By RJ Owen
December 29, 2008

The real problem with mobile development is that you need to learn a new language. Every platform currently has their own unique language for writing applications, and some of them are downright obtuse (I'm talking to you, Objective-C for iPhone.) With the number of mobile devices and mobile internet connections exponentially rising, it was only a number of time before someone made it easier. Enter PhoneGap.

qooxdoo Playground

By Rich Tretola
December 23, 2008

Have you seen the new playground sample environment that was recently released by the creators of the qooxdoo JavaScript framework? My development life has concentrated mostly on development for the Flash Player over the past few years so I haven't been very involved in the JavaScript frameworks. So, the playground is great way to introduce someone, like myself who hasn't used the framework in the past to the qooxdoo syntax. The playground allows you to edit and run the sample code provided to help you get a feel of the syntax. Check it out at http://demo.qooxdoo.org/current/playground

Turbo-charging JavaScript - Trace Trees and V8

Persistence, performance, rich APIs and increasing broadband connectivity are all likely to make a huge difference for this latest generation of browsers, and the quantum improvement of JavaScript capabilities due to Trace Trees and precompiled JavaScript will likely play a major part in that evolution.

Seeking Ubiquity

By Kurt Cagle
September 9, 2008

The command line is perhaps the most fundamental of all user interfaces - at a terminal, a prompt character appears that you can type in a command with zero or more arguments, then press the Return key to evaluate that command. As an interface it has some serious limitations - there are typically few indications about what specifically can be typed into that interface, or the action that will ensue once you do enter the line, but for programmers in particular, the command line is also the foundation on which every other user interface ultimately rests.

Reflecting Upon Chrome

By Kurt Cagle
September 3, 2008

Scott McCloud may not have intended to become the icon for Google's most recent efforts, but the choice of the veteran cartoonist (and semiotician) was a master stroke on the part of Google for introducing their new web browser, Chrome. McCloud's spare, clean lines, intellectual positing and delicious manipulation of symbols could not better have captured Google's secret skunkworks project. McCloud was commissioned to create a series of web comic pages that would explain the inner workings of the new Google Chrome browser, intended for release later this month, but a fan of McCloud's work apparently leaked the comic early, forcing Google to announce their latest (and arguably most audacious) project to date. As it turns out, the extra month or so of work probably wouldn't have made that much difference - even in beta, it is likely that Chrome has completely changed the balance of power on the web. Rumors that Google has been working on a web browser have been repeatedly heard for years now, but the assumption has long been that Google's physical proximity to Mozilla's headquarters and its general commitment to server-side technology precluded any real benefit for Google in building a browser of its own. Those assumptions, however, appear now to have been wrong.
