mercury vapor lamps are not a thermal light source, though

Mexico is serious about junk food. The cereal boxes in the stores don't have cute cartoon characters on them, and I tried to send somebody a box of chocolates and it got seized by …

I forgot about the AC mains :) My experience with embedded stuff is very limited -- just some hobby projects on the Pico. From what I've read, though, the on-board oscillators (the…

This is a harder problem than it seems. I've been thinking and reading about it for a side project, but haven't done much testing yet. There are a few places to get the current tim…

Yep: https://vimdoc.sourceforge.net/htmldoc/digraph.html I started using them a long time ago to type Greek characters, but then I switched to vscode with a vim extension and it di…

It does have the title going for it.

I shut my computers all the way down when I'm done with them. I like a clean slate when I return.

Is there a difference, though? "You think you know so much because you read a book, but I actually lived it so I really understand it." At best you understand your own experience, …

I've always been a stickler for being specific about which regex language your thing accepts, and whether it is to match any substring, or a prefix, or a suffix, or the whole thing…

The median age in America is about 40, so depending on how you define old the majority could go one way or the other.

I switched out asio's epoll backend for its io_uring in a database server and CPU utilization shot up. Probably depends on usage and the specifics of how it's integrated into the e…

Patients don't care about all of that medical mumbo jumbo, they just want to feel well.

I haven't studied history or political science, but I suspect that a bunch of cooperating individual local municipalities can as easily lead to war as to federalism. The Federalist…

I think it might have been a cognitive development thing, but at some point in high school, Stroustrup's "The C++ Programming Language" just kinda clicked for me, like I hadn't bee…

You got downvoted, but you're correct. Obligatory XKCD: https://xkcd.com/927/ > Personally I prefer lisp 1 languages, like scheme. Even there, though, there was a split over r6rs, …

Seeing what came later with gauge theories and more speculative stuff like loop quantum gravity, you can't blame Einstein for thinking that the theory of everything might take the …

You can do this as a convention in javascript since 2015, but I haven't seen a library that does it: > function foo({a, b, c}) { ... return {x: a, y: b, z: c}; ... } undefined > fo…

This made me go down a rabbit hole of techniques for separating sodium and chloride from urea/ammonium/ammonia solutions. I wonder if it could ever be made viable when compared to …

I remember hearing about an interview problem from a while back, and the trick was to use exclusive-or. Now I understand why.

Urine can contain too much sodium, and pharmaceuticals.

Yes, it's often the randos who feel this way.

C++ is a rather old programming language.

This is true. To be fair, if you use only the Linux syscall interface, then a program that you compiled on x86 in the 90s will probably still run anywhere today. Linus is adamant a…
