tom_alexander··on Climate goals go up in smoke as US datacenters turn to coal
Quoting that comment:

tom_alexander··on Radio Garten
I think this was posted shortly before the 2022 invasion of Ukraine. I remember the night before the invasion listening to a station right by the border, remarking on how normal the radio was.
tom_alexander··on A macOS terminal command that tells you if your USB-C cable is bad
I'm curious as to why it is so expensive? Admittedly I know very little about electronics, and naturally the validation testing that a cable manufacturer does is going to be more thorough, but for consumer-grade testing couldn't we just have an FPGA or microcontroller scream the fibonnaci sequence in one end and another listen for the fibonnaci sequence on the other end? Sort of like memtest but instead ramping up speed until the transmission becomes garbled.
tom_alexander··on The least amount of CSS for a decent looking site (2023)
If you're just concerned about light vs dark, then this article (which was posted to HN) does an auto/light/dark toggle button without javascript, and it shows using CSS variables for your colors: https://lyra.horse/blog/2025/08/you-dont-need-js/

FWIW you can add a light/dark toggle button without any javascript. You only need javascript if you want to persist that preference in localStorage.

Here is an article that was posted to HN which implements the three-state (auto/light/dark) toggle in HTML and CSS only: https://lyra.horse/blog/2025/08/you-dont-need-js/

tom_alexander··on Mind the encryptionroot: How to save your data when ZFS loses its mind
I use native ZFS encryption because it makes it super easy to share encrypted datasets across dual-booted operating systems. AFAIK Linux does not support GELI and FreeBSD does not support LUKS. DragonflyBSD supports LUKS but then no ZFS.

Also, that way I can have Linux and FreeBSD living on the same pool, seamlessly sharing my free space, without losing the ability to use encryption. Doing both LUKS and GELI would requiring partitioning and giving each OS its own pool.
