I have created a 15 minute screencast that will show you how to Debug JavaScript with Firebug. I cover a number of concepts such as using the console, interactive debugger and timer features of the Firebug extension for Firefox. If you haven’t tried Firebug yet, I’m sure that this screencast will convince you to make it a part of your JavaScript coding workflow.

I hope you enjoy my first screencast! I plan on doing a few more over the next couple of weeks, so I would appreciate your feedback.

If you have a digital camera and Photoshop CS2, you should take a shot at creating a High Dynamic Range (HDR) Photograph.

If you’re writing AJAX code and/or standards-based web pages you should be using Joe Hewitt’s Firebug extension for Firefox. Version 0.4 has just been released and is the most significant upgrade to date. I have been beta testing this version for a couple of weeks now, and I can’t image developing without it. One of the greatest new features is a JavaScript Debugger that allows you to simply add breakpoints to your JS code, then step through your code line by line, and inspect local variables and the call stack. There are tonnes of other great features, so head over to Joe’s site and give Firebug a try!

iShowU is a free application for OSX that allows you to create screencasts. The software works very well and is capable of outputting video in any format that can be produced by Quicktime. The only downside that I can tell, is that out of the box, the software cannot export as FLV or SWF.
