taejo··on Googling 'abortion clinic near me'? The top result often an anti-abortion clinic
Nobody's ever in urgent need of an anti-abortion.
taejo··on A regular expression to check for prime numbers (2007)
And via Parikh's theorem, with a one-symbol alphabet, regular and context-free languages are the same.
taejo··on Earth's rotation, with the camera locked to the sky instead of the ground
I see what you see but I'm not sure whether it's a real effect or just an artifact of the photography. There must be some adjustment of exposure to have both the daytime and the nighttime well exposed, so it may just be the changing exposure that makes the brightness of the horizon non-monotonic.
taejo··on Earth's rotation, with the camera locked to the sky instead of the ground
Yes, I think those are the two Magellanic Clouds visible to the right of the center of the image.
taejo··on Earth's rotation, with the camera locked to the sky instead of the ground
The linked source names the mount used, the Sky-Watcher Star Adventurer, but yes, you could replicate this in post, except that the frames have exposure times of up to 45 seconds, which would give star trails within individual frames.
taejo··on Earth's rotation, with the camera locked to the sky instead of the ground
An equatorial mount keeps the camera pointing in a fixed celestial direction by rotating at the same rate as the Earth in the plane of the equator. It's essential for any long exposure of the sky where you don't want star trails, the unusual thing here is having the horizon in frame.
taejo··on Travel across Germany with the 49 Euro ticket
But the fee that the GEZ used to collect (the Rundfunkbeitrag) does still exist and that's what a lot of people call it even the entity that collects it has a different name now, which doesn't make a difference to its effect.

I believe there are taxes in Germany that are zweckgebunden (legally bound to be used for a particular purpose), but the Soli isn't one: there were political justifications for its introduction, but it goes into the general fund and the government doesn't have to use it for those purposes.

taejo··on Wikipedia user edits over 90k uses of “comprised of”
> However it looks like Esperanto also has “liva”. Turnu liven tuj post la angulo ~= Turn left immediately after the corner.

If you wanted to be understood, it'd be better to say maldekstren though. I'd never heard of liv-, English Wiktionary lists it as "neologism, nonstandard" and Reta Vortaro as "malofte" (infrequent).

taejo··on Wikipedia user edits over 90k uses of “comprised of”
Esperanto dekstra only means right, the direction/side, though, and so maldekstra only means left, the direction/side.
taejo··on De-Stressing Booking.com (2019)
To get into a medical trial you a) know it's a trial b) get informed that you might get a placebo c) consent to participate in the trial.

If a pharmaceutical company was discovered filling 30% of pill bottles they sent to pharmacies with placebos, they'd be sued unto the eighth generation.

taejo··on What are the most common tinnitus frequencies? (2015)
AIUI tinnitus is the name of the symptom, not a specific disease, and it's still tinnitus whether it occurs occasionally, frequently, or constantly.
taejo··on Now You Have Three Problems – A Story about Parsing
A parser for Things

is a function from Strings

to lists of pairs of Strings and Things.

taejo··on Push notifications are now supported cross-browser
No. Three strikes means you're out on the third strike, not the fourth.
taejo··on Give babies peanut butter to cut peanut allergies, study says
Looks like it's what's called Erdnussflips in Germany
taejo··on Show HN: Can you beat my dad at Scrabble?
The usual thing in this case is to call it the 7th highest-scoring word (but call all of those above it the highest-scoring)
taejo··on They thought loved ones were calling for help. It was an AI scam
> to always hang up and call my number

She needs to be sure to do this before saving "your new" number. I've read reports where even after the adult child has discovered the scam and explained it to their parent, the parent continues to insist to the child that "you told me"... having saved the scammer's number under the child's name, they struggled to accept that the messages their phone said were from the child were from somebody else.

taejo··on Understanding British Money: What's a Quid? A Shilling? (2020)
The South African rand was indeed also introduced as half a pound in 1961 (technically half a South African pound, but that had been equal to the pound sterling except 1931-1933)
taejo··on Costa Rica’s enigmatic addresses (2021)
Except in Kyoto, where the streets do have names (I'm not sure if they're used in addresses, though).

And Mannheim in Germany is kind of Kyoto's mirror image: in a country of named streets, Mannheim has numbered blocks.

taejo··on Did the Music Business Just Kill the Vinyl Revival?
My grandparents had something very similar on cassette... no tidbits even, just, "1234, Greater Spotted Swallow [birdcall]" (the numbers referring to an accompanying book). My sister and I must have spent listened to those two tapes dozens of times.
taejo··on Finding the Darkest Pencil
Everything I see has a "uni" wordmark for the pencil company. However, AIUI mitsubishi more or less means "three rhombi" -- the companies are both named after the same family crest.
taejo··on New Go-playing trick defeats world-class Go AI–but loses to human amateurs
It's kind of weird: looking at the board in the article as a Go player, I would say the game is over and white won. But they're using a ruleset (Tromp-Taylor) which is commonly used in computer Go but almost never between humans, precisely because it requires you to play past the point where it's completely obvious that the game is decided.

So it's not clear that humans understand the rules and computers do not: humans play a slightly different game than the rules the AI is being evaluated against.

taejo··on Germany's blanket data retention law is illegal, EU top court says
In this case (IIRC) two service providers went to court and the law was put out of force for them, at which point the federal agency in charge of enforcing it decided not to do so until the matter was resolved by the highest court. So in some sense it did work.
taejo··on “Quantum-Safe” Crypto Hacked by 10-Year-Old PC
As a kid who chronically forgot to bring her calculator to school for about 12 years straight, I can now do long division well enough that I sometimes do it rather than get up to fetch my phone from the other room. It's also how I do division in my head.

I did pursue mathematics academically but I don't know if it ever came up in university math; more so in physics and computer science.

EDIT: apparently what I do is "short division", which is just long division but you don't write down all the steps.

taejo··on The Ring-a-Ding Numeration System by Jim Henle
From the article:

> The rings must be nested. The innermost ring must have a ding. No region can have more than one ding. Those are the only rules.

According to these rules the intermediate results are not valid numbers

taejo··on Typography is impossible (2016)
To expand on that for those that don't know, traditionally all font sizes had names, like Great Primer for 18 pt, Ruby for 5.5 pt, and many others. https://en.wikipedia.org/wiki/Traditional_point-size_names
taejo··on Sleep experts say Senate is wrong: Standard time, not DST, should be permanent
Aren't the boundaries of time zones federally defined? Does this bill change that? My understanding previously was that the only choice states had was between summer DST and year-round standard time. Otherwise California could have switched to year-round Mountain Standard Time instead of lobbying Congress for year-round Pacific Saving Time.
taejo··on Storing UTC is not a silver bullet (2019)
In most jurisdictions the DST rules and timezone offset change rarely. In some jurisdictions, they change more frequently. Over the whole world, they change often (dozens of times per year).
taejo··on John Locke’s recipe for Pancakes (2021)
Orwell is also good on pubs: https://www.orwellfoundation.com/the-orwell-foundation/orwel...
taejo··on Saffron, the most expensive spice (2018)
Warm, honey-like, slightly earthy, very slightly spicy
taejo··on Best Wordle guessing strategy
> One strategy which is obviously optimal is to use minimax (recursively, not like Knuth's Mastermind strategy which was mentioned by @christiangenco), however this strategy is not computationally feasible.

With some restrictions it's possible to do a full minimax. In that case, you still don't know if it's optimal, but you've at least got an upper bound. And it turns out, it's possible to guarantee victory while finishing in an expected 3.554 guesses. Alternatively, you can finish in an expected 3.212 guesses if you don't mind a small chance of taking more than six guesses.
