The Autodidacts

Exploring the universe from the inside out

Autodidacts Newsletter #24

One newsletter with more new posts than I published in all of 2025.

On Dec 31st 2025, I boldly announced that I was thinking of trying to publish a vast quantity of posts, in lieu of a handful of long-chewed-over deep dives.

Feedback came in 69:31 in favor of the experiment. Despite my encouragement of honest/blunt feedback, I assume a slight bias toward positive feedback, but the sentiment was probably still >50% positive, which meant it was up to me — and I thought, let’s go for it.

In the past month, I published four times more posts (24) than I published in all of 2025 (6).

I’ll be the first to admit: they aren’t as good. But this is not the beginning of a long slide into short-form clickbait and tech tutorials. This post-a-lot-and-see-what-sticks experiment is temporary, and calculated to do two things: 1) give me a lot of practice writing, and 2) create a large quantity of quietly useful posts that help people solve problems, and also bring in new readers for the more philosophical essays, by giving search engine exposure. In the long run, I plan to continue the gradual transition — which this experiment has temporarily interrupted — toward more in-depth posts and perennial topics.

Five or six of the posts are general-interest. My favorites are probably Human Beings are Waterproof and Dostoyevsky Isn’t Difficult. There are also a couple of posts on sleep (a favorite activity of mine). I drafted many philosophical posts, but I tended to get cold feet about publishing them when they were still raw, and fall back on tech how-tos.

I tried to put enough jokes in the niche tech tutorials to make them modestly entertaining even for people who don’t have the problems they solve. I enjoyed writing about Patching KOReader (because I actually fixed it), Split Testing in ~50 Lines of JavaScript (more technically in-depth than some), and the psychology of Ghost signup spam (because I made funny memes).

Here’s the full list of posts:
