Web development

• More Performance Tips - An article on how to improve JavaScript performance when generating web pages using DOM. I'm glad Microsoft is starting to publish more articles on how to write faster and better code for their browser (IE). Now I wish they would reflect more on how to work around IE bugs.
• A huge gotcha with JavaScript closures and loops - Blog post discussing function object creation inside another function. Basically the browser is free to reuse the inside function object, so if you are trying to create an array of them you might end up with the same function instead of having a collection of distinct objects. My biggest surprise, however, came from the fact that ECMA 262 script specification allows the script host to either reuse the function object or to recreate it. I guess specification gives this choice to script host developers for performance reasons. I don't like it though. Whenever there's "either-or" choice some people go one way, while others go another. Usually this difference won't matter until much later and a lot of time will have to be spent to figure out what's happening.
• JavaScript Articles - A small collection of good articles on advanced JavaScript features. There are lots of examples and the same material is often presented from several points of view to make understanding an article easier.
• IIS Server Pro - A lightweight tool to control IIS server from system tray and create multiple websites (same IP, different root on different ports) on Windows XP/2000.
• Internet Explorer Developer Toolbar Beta - A new toolbar from Microsoft to help web developers (who target IE). It offers some interesting features, but I still like Web Accessibility Toolbar better. Most of the functionality is the same, but there are some small differences (in what and how they outline on the page), so it makes sense to have and use them both. The biggest complaint I have about the new IE Developer Toolbar is that it only allows web page inspection. It doesn't let (or I couldn't find how to do it) developer to modify CSS (for example) and immediately see the results.
