I got tired

I have been blogging here for the last 20 years. Every Tuesday and Thursday, quite consistently, for two decades. But last year, without planning it, I got tired and stopped. Not sure why. It didn't correspond with any life events. Nothing interesting or notable happened. I just stopped. I did find joy on TikTok and amassed a small group of like-minded...

I wrote a Tiny Virtual Operating System for a 300-level OS class in C# for college back in 2001 (?) and later moved it to VB.NET in 2002.
