Where I've been, and the future of this blog
Recently, I got an email from a reader who noted that I hadn't published anything in a little while, and he said he hopes I'm doing well. The truth is, some days I am and some days I'm not. I want to share a little bit about what's been going on, and what

Let yourself fall down more
Last week, I got a pair of inline skates. I haven't had skates since high school, about twenty years ago. The first day I put them on and skated, I didn't fall down. The second day I put them on, I fell down a lot, and I'm more proud of that. I made a lot

Some good English word datasets
I'm working on a silly word game right now, which means I need a list of words for it. I can't rely on the system word list, since this is for a web project. I'd also like, ideally, multiple lists of words with different criteria: most common words, all w

Making niche solutions is the point
I got a 3D printer recently, and got to work using it. When I shared one of the first things I made in a private Discord, someone commented that "This is the most niche thing I've ever seen someone design/print." That, my friend, is the point: that we can

3D printing my laptop ergonomic setup
Apparently, one of my hobbies is making updates to my ergonomic setup, then blogging about it from an Amtrak train. I've gone and done it again. My setup stayed static for some time, but my most recent iteration ended up letting me down and I had to chang
