Protoarc. I think it’s the same guys who produce the “gameball” trackball. With cheaper sensors and switches, I’d guess.

Trackballs and vertical trackballs.

Not only are they better for my wrists and allow extremely fast movements in-game, but also this:

Keep in mind that more surface area usually means more bacteria. Afaik there’s is nothing wrong with the usual changable filters (although there are a few horrid ones).

But many private households tend to underestimate how dirty these things get, even after a short time.

Since water supplied by the municipality is usually fine and most bad stuff happens as a last-mile problem, I shower in the morning (which I have to do anyway, but it also flushes most pipes) and then wash out a large stainless steel beaker before filling it up and drinking from it for most of the day.

I’ve only used an LLM (you can guess which one) once to write code. Mostly because I didn’t feel like writing down some numbers and making a little drawing for myself to solve the problem.

And because a friend insisted that it writes code just fine.

But it didn’t. It confidently didn’t. Instead, it made up something weird and kept telling me that it had now “fixed” the problem, when in reality it was trying random fixes that were related to the error message but had nothing to do with the actual core problem. It just guessed and prayed.

In the end, I solved the problem in 10 minutes with a small scribble and a pen. And most of the time was spend drawing small boxes, because my solution relied on a coordinate system, I needed to visualize.
