Thanks. The first article has more info, e.g. that those beetles are flightless.

But that makes me suspect that they spend a lot of time on one tree, only pollinating that tree, which would be pointless because there is no exchange of genes.

I ripped music from both CDs and Internet radio (not Spotify). I remember there were definitely em dashes in those from Internet radio, but I'm not sure whether they also occurred in those from CDs — those filenames probably came from an online DB. Of course the Internet radios might have ripped the music in the same way.

I used to have ripped music that had em dashes in the filenames. But several music players displayed a question mark for it. So I replaced them all with a hyphen.

I don't think that the author has ADHD, because they used to be more attentive in the past. In the case of ADHD, it was also the case as a child.

I also got the diagnosis of ADHD (inattentive type) a few months ago, in the interviews they asked whether I also had these symptoms as a child. Not easy to figure out because as a child things like finishing things on time are not so important yet, and my high IQ compensated for a lack of focus. Only in secondary school it became a problem, and my grades dropped.

As a hobby mathematician, I agree. I know quite a bit about rings and ideals, but I don't understand much from the article on Rees algebras. Wikipedia has a lot of articles on mathematics that are explained badly, I prefer to find information elsewhere, typically I ask an AI for a good introduction on a subject (and usually that links to PDFs with over 100 pages that keep me going for hours).

If engine A uses the results of engine B, and engine B uses the results of engine A, there is a problem :-).

Indeed, Perplexity is so much more useful to me, because I usually have a question, that I can just enter and get an answer that usually is correct. And it also gives sources so I can check the answer and find more info. Try e.g. typing "what does defer do in Zig" into a search engine, one of the last questions I asked. Perplexity immediately gave a clear answer.

I only use a search engine to find a specific website if I know the website should exist but don't know its URL, e.g. the website of a festival.

I was more lucky, I bought a book about C64 assembler in a second hand book store with my pocket money (must have been in 1989 or 1990).

I started a little later with the Commodore 128. I must have spent thousands of hours programming in Basic and assembler. I remember wanting an assembler instead of putting bytes in memory, and saw one in a supermarket when my mom took me shopping, that's how popular computing was then.

It was fun, but primitive, when I learned Pascal at university I was impressed by the functions with a name to which you can pass arguments!

It doesn't even work for most instruments, nearly every instrument can sound differently depending on how you play it. A violin sounds different depending on how close the bow is to the bridge, a piano sounds different depending on which pedals are pressed and whether the lid is open, a trumpet sounds different depending on whether there is a cup in front of it and where. Experienced musicians know how to use these effects to create the right feeling.

And that's only based on how little I know about this.

For me glycine helps amazingly. It's an amino acid that the brain needs during sleep. I take about 5 grams in water about an hour before I go to sleep. I'm not sure how much the glycinate in magnesium glycinate has the same effect.

Oddly, it has the opposite effect as sleeping pills on me, it doesn't make me sleep more but I'm more rested when I wake up. It even happened a few times that I only slept 5 hours but still could focus well at work and bike intensively for an hour in the evening, without glycine that was impossible.

At 20 euro/kg I think I'll take it for the rest of my life, and it probably will add a few years to my life.
