AJAX Tutorial
AJAX is a powerful tool that allows javascript to communicate with PHP (and therefore your MySQL database or anything else available through PHP). For example, after a page has loaded, an event (button click) could trigger dynamically updated content without a full page reload. I currently use AJAX in several spots on my website; a couple of those spots include the explore images and explore tags snippets, comments, and rating. There's another article here that describes another AJAX application I wrote.

Cross-browser AJAX Image Explorer
I recently added a snippet to my website that mimics some of the fancy Flash-based image browsers with dynamic image loading, smooth scrolling, mouseover opacity effects, and cross-browser functionality. This article will explain how I did it. If you have suggestions for improvement, let me know in the comments! You can see how this works by browsing to any image page on my website and using the applet in the upper right-hand section. I'm not going to explain all the nitty-gritty details, but I'll go over the major functionality and include the full source code so you can try it out yourself.

Transferring a Vista Install to a New Volume
I recently decided to upgrade my O/S hard drives and didn't want to go through the hassle of re-installing Vista and all my applications and drivers.

PHP Optimizations: Cache Control, Profiling, and Web-based Reporting Tools
After three years of editing my website here and there I noticed that certain pages, specifically my gallery, were getting really slow - like taking 7-10 seconds to load the page. In an effort to optimize my code, I learned a couple techniques for optimizing PHP that I'll document in this article. First is a simple way to control what clients (and proxies) cache from your website. Second is a useful website I found to get fairly detailed reports on my webpage composition. Finally, I'll present a simple profiling library I wrote to gather and analyze page load-time data.
