I enjoy things around information theory (and data compression), complexity theory (and cryptography), read hard scifi, currently work on weird ML (we'll see how it goes), am somewhat literal minded and have approximate knowledge of random things. I like when statements have truth values, and when things can be described simply (which is not exactly the same as shortly) and yet have interesting properties.
I live in the largest city of Switzerland (and yet have cow and sheep pastures and a swimmable lake within a few hundred meters of my place :)). I speak Polish, English, German, and can understand simple Swiss German and French.
If in doubt, please err on the side of being direct with me. I very much appreciate when people tell me that I'm being inaccurate. I think that satisfying people's curiosity is the most important thing I could be doing (and usually enjoy doing it). I am normally terse in my writing and would appreciate requests to verbosify.
I appreciate it if my grammar or style is corrected (in any of the languages I use here).

Do you mean that it being consistent and predictable is a feature, or that it being high enough is a feature? (IOW, would consistent lower capacitances be better?)

"it should be about as labor-intensive to wire wrap through-hole components as it is to solder them"
Mass production uses wave soldering. You simply insert all the parts into the board, soak the board into molten solder, and pull it out. bingo, the full board is soldered within seconds. You can't wrap all the wires within seconds."due to wire shape, unwanted capacitances are kept much smaller in wire wrap (compared to e.g. a 2-layer PCB),"
Due to physical construction, unwanted inductances are much higher compared to a PCB. Even for advanced wire-wrap boards with ground planes (people used them in the late 80s during wirewrap's last days), it's still difficult to match a PCB's performance. A typical 4-layer board's signal layer is 0.1 mm above the ground plane, a wire-wrap board it's typically 5 mm, causing a 40x increase of loop area."no need for explicitly making multi-layer PCBs: the problems of routing, possibly stacking layers (for >2 layer ones), coating vias, etc. just go away."
One huge motivation to use a multi-layer PCB in modern designs is not even extra layers for the signals, but to have solid power and ground planes that contain nothing but solid copper. A copper pour on a multi-layer PCB naturally forms microstrips, the simplest kind of microwave transmission line, which is required to support high-speed digital signal transmission. Likewise, the capacitance between the signal layer and a ground plane is a feature, not a bug. Because of its planar circuit nature of a PCB, characteristic impedance is tightly controlled and extremely reproducible. Overlapping wires over a ground plane do not have a consistent characteristic impedance.Even in lumped circuits and analog designs when controlled impedance does not matter, a solid ground plane is often still important to minimize loop area and parasitic inductance. Modern power MOSFET's switching speed is reaching 100 volts per nanosecond.
Standard wire-wrap construction is ill-suited above 10 MHz. Even back in the late 80s when electronics is made of really slow through-hole parts by modern standard, wire-wrap already started to show serious signal integrity problems.

But... Believe it or not. All of these problems I listed have been solved already in the 80s by combining the best of both world. The final next-gen invention was called "Multi-Wire" circuit board. It looks like a normal PCB but its inner layer uses insulated wires for connections, allowing overlapping traces. The ground planes and outer layers are similar to PCB. Reportedly,
IT can convert a multi-layer PCB design with 12 signal layers to a six-layer board with just two signal (wiring) layers.
But it was an highly expensive technology, and did not see much uses outside niche high-end applications. Today Hitachi is one of the few companies that still offer this service.https://www.swtest.org/swtw_library/2013proc/PDF/SWTW13-22.pdf
@niconiconi Do you have a source for not-terribly-expensive wirewrap tools and various components (or small pcbs) with wirewrap posts?
@dwarf This looks really amusing. How did you get it to happen?
@xenolune@useless.merveill.es Pirate flags were intended to be invitations to surrender under threat of bodily harm though :/
You meant The Lost Steersman (3rd book) as opposed to The Language of Power (4th book). Also, the second technically contains intelligent aliens, only the characters in it do not recognize them as such, and it contains some other alien life (hard to say whether characters recognize it as alien).
There's a spectrum of "humanness" that aliens in fiction display: with e.g. Solaris' ocean on one end (with its inscrutable thought processes) and (most of) Star Trek/Star Gate aliens on the other (with their social structure that one would not be surprised to find in some group of humans).
I think you are not after more realism (i.e. more towards Solaris) in this axis, but rather in terms of physical construction of aliens that should match the environment. Please tell me if I'm wrong.
Hal Clement is a good source of various kinds of socially very human-like (are always curious, have the concept of asking questions, form families/bands/...) aliens that live in weird environments. His stories concentrate on some aspects of the environment, and so the aliens might not be as fleshed out as you'd want (pun intended).
Some examples: Weirder/less concrete aliens: Foundling Stars sketches aliens that live at long timescales and large sizes. Proof sketches aliens that are made of plasma (or rather, of plasma currents) in stars (but it focuses more on the inferential distance between them and humans than on their composition). Uncommon Sense describes some aliens that live in vacuum and weird sensory apparatus they have (with very little attention paid to any other part of them). More concrete ones: Mission of Gravity describes aliens on a high-gravity, water-ammonia world. Close to Critical describes a water-based world where surface conditions are close to critical conditions of water with life on it. Planetfall describes aliens that perceive via vibration and EM wavelengths of VHF at the shortest.
I'm probably forgetting some other obvious authors, will think some more.

Ignorance _of the facts_ is a defense (at least in CH and PL, I presume in US too), ignorance _of the law_ usually isn't, but various countries have weird exceptions to that (to the tune of "didn't have a way to determine what the law says"). In this case we'd be talking about ignorance of the law. @molly0xfff

First, second part: There are two reasons you would care. One of them is safety of people you directly interact with and the other is Kantian approach to affecting the societal outcome.
For the first of these, I expect those people are doing some estimates of their own or are following some rule-based approach. I'd ask them. If that fails to yield anything useful, I'd put myself in their position, see what I'd be doing then, and behave in a way that me-in-their-position would find fine. Thus the problem reduces to the original one.
For the second, I stopped trying to reevaluate it a long time ago, because I consistently concluded that this produced requirements that were less strict than the ones produced by other concerns. (That's basically always the case when you aim at a lower chance of contracting covid than the societal average.)
I'm going to redo my estimates for the original question soonish, so will write them up while doing them in a following post.
@alilly Different people might understand your question differently: do you mean _exactly_ those names, or the families of those names and some subsets of their standard short forms (like Alex for Alexandra.... there would be more in languages other than English)?
@alcinnz What you're describing sounds like an improved version of ublock's element picker. If you did the selector alone, it'd probably be welcome and useful in ublock.
(That said, that picker has sadly gotten less useful over the years due to advertisers avoiding elements that _can_ be found using css selectors.)
@moonbolt I just tried to think of anyone I know whose commonly-used name is longer than 2 syllables and I failed (everyone whose name would be longer has adopted some more-or-less standard shortening for daily use). This suggests to me that this is how it might trend for your name, so you might wish to pick a 2 syllable short version yourself before people start trying to find one that works.
@noelle
Probably not exactly that either, or at least it's unclear to me whether "worst day" should include "coincidentally being sick of a bad cold" or similar things. I would guess (without direct experience) that they want to ask one about something like second percentile of days (and would be nice if that was specified explicitly).
@alexis Load cell? Wouldn't it be easier to measure pressure at the bottom?
I still get amused once in a while by the combination of pomp and absurdly detailed requirements in the Swiss constitution:
"Im Namen Gottes des Allmächtigen!
Das Schweizervolk und die Kantone,
in der Verantwortung gegenüber der Schöpfung,
(...)
gewiss, dass frei nur ist, wer seine Freiheit gebraucht, und dass die Stärke des Volkes sich misst am Wohl der Schwachen,
geben sich folgende Verfassung:
(......)
Der Anteil von Zweitwohnungen am Gesamtbestand der Wohneinheiten und der für Wohnzwecke genutzten Bruttogeschossfläche einer Gemeinde ist auf höchstens 20 Prozent beschränkt.
(...)"
@forteller@octodon.social Does it claim to be hot? Is it actually hot? Is it using lots of CPU?
For example, if the thermal sensor misreported the temperature and claimed it to be higher, this could be the effect (fans at full throttle, CPU throttling).
@moonbolt Similar to how some pictures have two sticky interpretations (rotating dancer, face or two vases, ...), your appearance is very close to different interpretations. Shift involves something tiny changing that changes the interpretation that people have when looking at you (there's no stickyness involved -- that detail is large enough to overcome it). The change is small enough to not/nearly not trigger human motion detection reflex. Thus, people (or at least humans) don't notice the moment of shift, but can always easily tell your state.
@PeterCxy Ah, I see: among the ones that probably didn't had any optimizations applied to Date generation. @niconiconi @robookwus
What I'm confused about is anyone who actually tries to write optimized Date generator (you implied that happens?). This is a case when someone clearly cared about making it fast, and did the more complicated thing to do so. @niconiconi @robookwus
