Background textures of work An Article by Lucy Keer lucykeer.com One thing I've been enjoying about working as a technical writer is that the minute-by-minute texture of the work feels right. Something about formatting text, faffing about with SVGs, trying to rewrite a sentence more clearly... it's just enjoyable in itself, and I feel at home with it. ...Working as a programmer was very much not like that. There's something in the rough vicinity of professional dev work that I do like, which I could probably label as 'iterative hobbyist tinkering with websites'. I like working on something with a strong visual component, and I like to be inside of a fast feedback loop, and I'm mostly interested in just somehow bodging through until it works. I'm not very interested in either the computer-sciencey side of programming — data structures, algorithms — or the software-engineerey side of making things run reliably at scale in a maintainable way. So maybe it's not surprising that the minute-by-minute texture of professional programming was just... kind of bad. Occasional fun bits when I got into something, but the background experience was not fun. workproductivitymaking
Wang tiles Wang tiles (Hao Wang, 1961) are a class of formal systems. They are modelled visually by square tiles with a color on each side. A set of such tiles is selected, and copies of the tiles are arranged side by side with matching colors, without rotating or reflecting them. The basic question about a set of Wang tiles is whether it can tile the plane or not, i.e., whether an entire infinite plane can be filled this way. The next question is whether this can be done in a periodic pattern. In 1966, Wang's student Robert Berger solved the problem in the negative. He proved that no algorithm for the problem can exist, by showing how to translate any Turing machine into a set of Wang tiles that tiles the plane if and only if the Turing machine does not halt. The undecidability of the halting problem then implies the undecidability of Wang's tiling problem.
