Scotch on the Rocks and WebDU were last week (see my WebDU Day 1 post here) and CFUnited is now underway. It looks like CFUnited will generate heaps of blog posts, so I’ll probably have a separate conference round up after it’s over – but for now, a few advance details for ColdFusion 9 (coming

Microsoft should consider this a forewarning — if the trend of the past three years continues, not one person who visits sitepoint.com will be using Internet Explorer by 2013. With all of the buzz about new Firefox this and Opera that, I thought I’d reacquaint myself with the browser-of-choice

Now well-established in it’s sixth year, WebDU in Sydney is the top Australian conference for Adobe-based technologies (primarily Flex and ColdFusion). The venue for 2008’s conference was the Sydney Convention Centre - a move away from Star City casino, where it has been held for the past

At the start of this year, I sat down to write the “Errors and Debugging” chapter of Simply JavaScript. I cracked my fingers, dove into the landscape of JavaScript debugging tools, and emerged very disappointed several hours later. At the time, Firefox was the only browser with a JavaScript debugging

Our newest book is now available in PDF format only—and it’s FREE! It’s called Firefox 3 Revealed: What’s New, What’s Hot, & What’s Hot. Here’s how it came about. When I first discussed the idea with Fabio Cevasco of writing an article that described all of

It seems that testing has been on the flavour of the week, which is apt really as I myself have been playing with RSpec a lot lately (Blog post forthcoming, once I finish up one of the projects that has been using said testing framework). Simon Harris from My hovercraft is full of eels describes a simple

Our friends over at 99designs are running a competition to win a MacBook, and there are only 4 days left: Just a final reminder that we are giving away a free MacBook to one lucky designer who submits a winning design to 99designs.com before June 20th.

Lots of news in open source this week! I sneaked in news last week of the Railo open source announcement. There’s been a lot of discussion and it seems that the move is seen, in general, as a very positive one. Gert Franz has posted an official announcement on the Railo blog, as well as some

Opera 9.5 is finally out after 2 years of development. Often the underdog browser of the big 4, Opera’s continuous dedication to web standards support has always been commendable. I’ve just been putting it through its paces on the SitePoint CSS Reference Live Demos, and it does extremely

We’ve all heard the stories of everyday people turning small sites into a healthy income that have allowed them to quit their day jobs and enjoy lives of online entrepreneurship. But if you’re yet to find that killer strategy to earn a profit from the Web, I’d like to introduce you to a brand

Building a web application with Google App Engine is quick and easy, and you have the power of the google distributed content delivery network and the ‘BigTable’ database at your disposal. So what’s it good for? When I was 14 my Dad bought a Commodore 64. I poured over the manuals,

Thousands of developers have gathered in San Francisco for Apple’s Wordwide Developers Conference 2008. The spotlight at WWDC is on the new iPhone 3G and the iTunes App Store, which is launching in July to bring (officially) native apps to iPhone and iPod touch devices, but web developers have

Last week Google tweaked their favicon (that little 16×16 pixel icon in your browser’s tab), changing it from an uppercase G to a lowercase g. Now, a change like this is normally something that shouldn’t matter — it’s not like they changed their actual logo to begin with
