Yes, I started it a very long time ago (most likely 1994 but that's before Wayback Machine, and I don't have my own archive). I should update the links on that page, but I've been focused more on my new site (http://www.redblobgames.com/), where I'm writing tutorials with interactive diagrams.
Longevity is a goal for my site so I try to focus on algorithms, design, and techniques, rather than specific platforms, languages, or code.
