taejo··on The web's clipboard, and how it stores data of different types
Part of the problem is a poor (or insufficiently DWIM) implementation of rich text copy-paste. If I copy text that has some parts bolded or italicised, that is indeed "the damn text I copied". But the fact that the source website happens to be 12pt blue Verdana should not override the fact that I'm writing an email in 11pt black Arial.

In many cases I do not particularly care whether an email is in 12pt blue Verdana or 11pt black Arial, I absolutely care about there suddenly being a big blue word in the middle of my otherwise-consistent paragraph.

So neither "rich text" nor "plain text" are really correct: often plain text is good enough, but sometimes it's easier to correct the rich text.

taejo··on Using the moiré effect to show different arrows to each observer (2018)
> Can you use a variable moire effect to create motion graphics?

Yes! https://www.creativebloq.com/animation/moire-effect-book-714...

taejo··on Companies Lobby Against Giving the Military the Right to Repair
The military-industrial complex is a complex of the interactions between the military and the industry that supplies it, not just the latter. It's the industry side of the complex that is opposing it, the military is asking for it.
taejo··on Finding a therapist who takes your insurance can be nearly impossible
Afaik there are many therapists who are qualified and want to take public insurance (reimbursement rates are actually pretty good compared to those for MDs) but in the '90s there was a formula developed for how many therapists are needed per capita, and only that many therapists get licenses to take public insurance. Since the stigma around mental health was much higher then, demand now completely outstrips supply, and the competition for the licenses of retiring therapists is fierce.
taejo··on We need to liberate the Postcode Address File
Though at least in Berlin it's pretty common for multi-family houses to have a separate wing (Seitenflügel) or rear house (Hinterhaus) that are reached by entering the street door of the front house (Vorderhaus) and then exiting through a door behind the staircase into a courtyard before entering the second building, and at least in some cases each building has its own set of mailboxes, all with the same address.

I regularly have the problem that deliverers don't read my delivery note and don't listen to what I say on the intercom, and go all the way to the top of the front house before realising I'm in a different building altogether.

taejo··on Tritone Substitutions
According to Wikipedia they are first cousins, not siblings
taejo··on Phish-friendly domain registry ".top" put on notice
There is bund.de for the federal government, with e.g. the interior ministry (Bundesministerium des Innern) at bmi.bund.de. But personenstandsrecht.de has nothing in the domain name or even the whois to indicate that it really is part of the interior ministry as it claims. There are links to it from bmi.bund.de so presumably...
taejo··on Turing's topological proof that every written alphabet is finite (2010)
The Turing machine has a memory, it can absolutely cope with symbols meaning something different depending on what appears before them. The trouble is that it can't distinguish between infinitely many distinct symbols on the paper tape. Turing here shows that a human can't do that either, so that is not a way in which humans have more computational power than a Turing machine.
taejo··on Turing's topological proof that every written alphabet is finite (2010)
Turing's goal here is to justify why a Turing machine captures the "intuitive notion of a computation". To his audience, a "computer" is a person with a stack of paper and a pen, following an arbitrary procedure. Turing shows here that, even though a person can potentially draw infinitely many drawings on a sheet of paper, that doesn't give them any more computational power then writing symbols from a finite alphabet into a grid of squares.

The machine he introduces also writes symbols onto paper with a pen and reads them. So he really is talking about pens and sheets of paper, it's not an analogy for something else.

taejo··on Born into slavery, he rose to the top of France's art world
> You can substitute "photorealistic" with "looks like the square (or rectangle) picture in the mirror".

Reflections in the mirror have depth and motion. Even without the viewer or the subject moving, the viewer can see depth in the mirror that isn't in a photo. In those respects, photos are more like paintings than mirrors. Of course, in other respects, they're more like mirrors.

taejo··on Coffee helped the Union in the Civil War
Some acids are bitter, e.g. in hops https://link.springer.com/article/10.1007/s00253-021-11329-4 and in bile https://www.nature.com/articles/s42003-023-04971-3.
taejo··on OpenLoco: Modern, open source version of the classic transport simulation game
Since we're nostalging about old train software, I'll mention JB BAHN https://jbss.de/hpg_eng.htm It's more simulator than game but I had a lot of fun with it as a kid
taejo··on Show HN: I made a puzzle game that gently introduces my favorite math mysteries
> However, if P = NP, there is no process that works here - there's nothing that is hard to do but easy to demonstrate, and therefore no zero knowledge proofs exist.

IIRC technically, there are zero-knowledge proofs for all statements in P: the proof is "prove it yourself", which the verifier can do because it's in P.

taejo··on Lawyer divorces wrong couple through dropdown selection error
England and Wales allow unilateral divorce, and at least the husband wanted to divorce, so even without this mistake the result would be divorce. The mistake must be in the details of the settlement, so there's a good chance it's a material cost that the lawyer who made the mistake or their firm can compensate for monetarily
taejo··on The ü/ü Conundrum
Interestingly, it seems that Japan does have a procedure for foreigners to officially adopt a Japanese name. Changing your name is often very hard, and doing it in a country where you're not a citizen might be completely impossible, depending on the country.
taejo··on The ü/ü Conundrum
And then never move to Japan (or any other country where names are expected not to have Latin letters in them)
taejo··on Defective C++
OK, set me right. How do you declare a member variable "m" of type "Complextype" in C++?
taejo··on Defective C++
I assume that's exactly the unnatural way that's being referred to. The natural way to define a member variable is

Complextype m;

which has the fewest tokens, is the easiest to read, and doesn't require extra memory/lifetime management or library types that didn't even exist in the standard library for the first decades of the language (i.e. std::unique_ptr) so certainly weren't the originally intended way to declare members but are workarounds for a problem in the original language.

Of course, the solution to this (and some of the other problems discussed here) in other languages is often make everything a heap pointer under the hood, and there are good reasons not to do that!

taejo··on Scientists put Jared Diamond's continental axis hypothesis to the test
In the rest of the comment you're replying to, the commentor indeed concludes that being as plausible as the first book means the first book isn't so convincing after all
taejo··on The end of Britain's weeks-long general elections
The Uniformed and Overseas Citizens Absentee Voting Act guarantees the right of US citizens living abroad to vote in federal elections in the state they previously resided in (not sure about US citizens who never resided in a state or DC)

Live free! Embrace heteroradicalism!
taejo··on Zeiss's "Holocam" turns glass windows into cameras
You're right about the strengths of the phone camera, and I also take many more pictures with it. But printing large prints, framing and hanging pictures is absolutely worth doing, much more than printing 4×5s to flip through. I love having them and everyone who comes into my home takes some time to look at them.
taejo··on Germany's inefficient love affair with open windows (2021)
Afair the rules about minimum temperatures that got loosened are all about requiring the landlord to provide sufficient heating that the home is livable (it must be possible to heat the home to 20°C during the day and 18°C at night with the provided heating). The tenant is only required to not damage the apartment by letting mold grow or pipes freeze.
taejo··on The economics of all-you-can-eat buffets (2020)
>This is several cartons; the largest carton you can buy is 1350 mL of milk.)

Even in other highly-lactose tolerant countries, I don't think I've ever seen milk sold in a carton or bottle more than one litre, outside of the US.

taejo··on C Is Not a Low-level Language (2018)
> > It believes that volatile storage is uniform in terms of latency and throughput.

> It doesn't, I don't think it even mentions terms like latency and throughput.

Yes, that's the whole point.

taejo··on Car allergic to vanilla ice cream (2000)
Plenty of cars that intermittently won't turn on in this thread, but I once had a car that intermittently wouldn't turn off... or at least the headlights wouldn't. I assume a relay somewhere was overheating and that was making it stay closed, but I never debugged it, and nor could my cousin who was an auto mechanic. We never tried too hard, though: I would just take the fuse out if it happened and put it back the next morning.
taejo··on IRC is the only viable chat protocol (2022)
If my workplace made every employee run an Exchange server rather than IT running one for everyone, I'd leave
taejo··on How to make cheese at home
Ricotta is properly made from the whey which is a by-product of making another cheese. Additionally, the souring comes not from lemon, but from fermentation of the whey itself. However, it's true that the term is commonly used in home cooking for plain fresh cheeses made from whole milk.

Your strained Greek yogurt sounds similar to labneh, which is delicious!

taejo··on Breaking java.lang.String
If the constructor here would take a const reference, it would have the same problem (the existence of a const reference doesn't preclude non-const references to the same object). If it took an argument by value, it wouldn't make a difference whether it was const or not, because no other thread could have access to the same object, because it would be copied.

In Rust, on the other hand, if there's a mutable reference to an object, there can be no other references to the same object at the same time.
