Aluminium is actually a better conductor than copper when you judge it by mass, not volume. I think also by tensile strength.

In any case there's a reason that large overland wires aren't copper, but steel-cladded aluminium. Copper will always have its applications but so does gold and yet we're not running out of gold to plate connections with.

In cases like windings requiring more volume is actually an issue, in the case of PCBs... no, despite Apple's insistence, it's actually fine to have a phone that's 0.2mm thicker.

For completeness sake there's Low Saxon "Slunt", note the n, meaning "rag" as well as "disorderly, dirty person". If you want to use it call a woman promiscuous have the decency to use the diminutive. Not related to German "Schlund", gullet, that'd be Slunk. I can't find any proper etymology but my guess would be that English lost the "n" at some point.

Funnier are words like Gröönhöker. That's the same roots as "green" and "hooker" but it's not what you think, it's someone who can hook you up with the green stuff, a greengrocer. Or the perfectly cromulent toponym Quickborn meaning "lively spring".

Unlikely as many Germanic languages have it, with similar meanings. It's a variant of "ja", yes. Add a bit of laconicy and you can make "Well." a sentence in itself.

How does executing a program actually work?

Way too long an answer for a lemmy post

It has an executable flag, but what actually happens in the OS when it encounters a file with an executable file?

Depends on OS. Linux will look at the first bytes of the file, either see (ASCII) #! (called a shebang) or ELF magic, then call the appropriate interpreter with the executable as an argument. When executing e.g. python, it's going to call /usr/bin/env with parameters python and the file name because the shebang was #!/usr/bin/env python.

How does it know to execute “main”?

Compiled C programs are ELF so it will go through the ELF header, figure out which ld.so to use, then start that so that it will find all the libraries, resolve all dynamic symbols, then do some bookkeeping, and jump to _start. That is, it doesn't: main is a C thing.

Is it possible to have a library that can be called and also executed like a program?

Absolutely. ld.so is an example of that.. Actually, wait, I'm not so sure any more, I'm getting things mixed up with libdl.so. In any case ld.so is an executable with a file extension that makes it look like a library.

EDIT: It does work. My (GNU) libc spits out version info when executed as an executable.

If you want to start looking at the innards like that I would suggest starting here: Hello world in assembly. Note the absence of a main function, the symbol the kernel actually invokes is _start, the setup necessary to call a C main is done by libc.so. Don't try to understand GNU's libc it's full of hystarical raisins I would suggest musl.

Pure SQL, as in relational algebra, is LOGSPACE/PTIME. Datalog is PTIME-complete when the program ("query") is fixed, EXPTIME-hard otherwise.

It's all quite tractable, but there's definitely turing-complete declerative langugages. Not just pretty much every functional language, but also the likes of prolog.

Functional is also declarative because control flow is implicit/unspecified.

What's actually missing is logic programming, of which the likes of SQL are a subset.

And to remember the whole thing: "Star" comes from steer, goes back to old ships which had their rudder and till tied to the side at the aft and specifically, when looking forwards, to the right as people tend to be right-handed. Thus, steering-side == right if you're looking forwards.

"Port" because that's the side the port is on if you land without risking damaging the rudder. Originally it was "backboard" because that's the board (== side of ship) that's (often) in the helmsman's back, English changed it at some point while everyone else kept it. The terminology goes back to at least Old Norse, probably earlier, that's just the earliest that's attested.

You mean like libc.so? Bold move, bold move.

And presumably the terms of the permit allow Israel to kick them out at their heart's content.

I gotta be honest Jerusalem is a thing I was overlooking but I still don't think Kahanites would be willing to do that. Some kind of compromise to be able to say that Jerusalem is (fully) Israel, one thing, but the west bank? It's just land. They don't want the people living there they'll either not take it, or take it without the people, no matter how disenfranchised.

I suppose this is more about annexing the illegal settlements. Ones which already have sky-high walls around them.

Occupying it. Meaning that Palestinians living there could not vote, and were subject to martial law. At the same time Israel administered things such as building permits which means that Israel could "legally" demolish "illegal" buildings.

I highly doubt they're going to annex anything that's full of Palestinians, not while the Kahanites are in power they're way too much into the whole ethno-state thing to do that.

I think non-Germans can’t understand the deep social guilt that’s been drilled into them since WWII.

Then why are you speculating about it.

when I was living there I asked some question I don’t even remember about the Holocaust of one of my German friends, and he quite politely told me “we don’t talk about that.” It’s a subject of guilt and embarrassment.

Yeah that's surely the only possible interpretation.

Truth be told: Just by using the term "guilt" you're parroting Nazi talking points. It's the precise type of rhetoric they're driving, and you're a dogwhistle's understanding away from "The Jews invented the Holocaust to shame Germany to keep it from being strong".

Maybe that's why people didn't want to talk to you about it.

For people actually interested in understanding it, instead of merely having an opinion: Start by distinguishing between "guilt" and "responsibility", the latter not in the sense of culpability, but... OSHA.

The whole Israel thing is actually distinct from that. If, tomorrow, Netanyahu, Ben-Gvir etc were to keel over and we'd have the second coming of Rabin, the collective sigh of relief in Germany would knock the earth off axis. The trouble is supporting, at the same time a) Israel to exist within its internationally recognised borders and b) supporting the same thing for Palestine allthewhile c) fascists on both sides making shit impossible.

There's been plenty of criticism within Germany towards the hesitant stance of the government. On the flipside, what you also don't see is German media -- also public, also state media (DW) sugar-coating what's happening in Gaza.

For the longest time the government kept to its age-old approach of working the Israelis quietly, in the background. Stuff that, on occasion, led them to relent on settlement projects etc. Germany did it that way because it was a way to influence things while keeping an in. That seems to be over because there's no "in" with Israel any more, they're simply not listening to things they don't want to hear.

In addition to that martial rape could be, and was, prosecuted as coercion and bodily injury. Corporal punishment of spouses (which would be a way around that) was legalised in Prussia in 1794, then outlawed again in 1812, in Bavaria the span was from 1756 to 1900 (introduction of the BGB).

Still takes a very special kind of conservative to object to categorising it as rape, and that's the exact type of conservative Merz is.

The exact same reform btw also made the law gender-neutral. "Rape" doesn't exist as a thing in itself in German law, in a sense, it's a name given to a specific aggravation of sexual assault:

(6) In especially serious cases, the penalty is imprisonment for a term of at least two years. An especially serious case typically occurs where

1. the offender has sexual intercourse with the victim or has the victim have sexual intercourse or commits such similar sexual acts on the victim or has the victim commit them on them which are particularly degrading for the victim, especially if they involve penetration of the body (rape), or
2. the offence is committed jointly by more than one person.

Gigaset produces in Germany.

It's fine memes are permitted to make jokes and it's more of a paradigm than vibe coding.

The one paradigm that's actually missing is logic programming, I would've gotten rid of unstructured to include it. The whole paradigm thing really only started with Dijkstra's rant about unstructured gotos (not the ones C has, in C you can't jump to the middle of another function).

Not reliably, no. Python is too dynamic to do that kind of thing without solving general program equivalence which is undecidable.

Use a static language, problem solved.

You’re back-tracking: now you are allowing, however intelligently, for cars in some instances

No I'm not: I'm not the one you think I am. "No rubber on asphalt, like, ever" is a stupid stance from the get-go. "Reduce individual car ownership as far as reasonably possible" is a statement I'd support.

You also sound British, which no offense,

Why, confusing me for a chap from our colony, how quaint. More on topic: Europe gets hot. Europe gets cold. Still there's bikes in Finland and bikes in Spain. Oh, Not Just Bikes has a video on Finns vs. Canadians.

Which company will get the contract to sell the city those ≥2500 cars—Ford, GM, Chrysler, Toyota, BMW, Tesla, or a Chinese variant? The one that lobbies best?

Probably the one that hands in the 2nd cheapest option ticking all the boxes. How do cities decide on which busses to buy? Who will build a bridge? This is not a topic specific to car rentals.

They were the reason some authorities made accommodations, which in turn made cycling seem more viable to more people, thus increasing the number of cyclists.

People never stopped cycling. People never started to believe that it's reasonable to close the primary schools of 20 villages and put kids into a single giant one.

I understand that it's harder to fix what's fucked up than to improve what was still functional but "oh it's hard" is not an argument with which you can counter "it's better". I never said it would be easy.

Not really because there's only a limited set of Lingua Francas and, say, Mali turning away from French in favour of e.g. English won't make French disappear.

They don't so much have a speed limit but they're required to stop giving you a boost at 25 km/h. Anything that uses a motor to go faster needs a license plate and everything.

At least in Germany bike lanes don't have a speed limit, you can drive as fast as you want as long as it's safe, you're in control, etc. Especially relevant when going downhill.

Sunday or leisurely drivers will go 10 to 25km/h, when you're fit, the road surface is good and the bike built for it sustaining 35km/h isn't much of an issue, fastest I ever went on my mountain bike with semi-slicks (so no racing transmission but no unnecessary friction losses either), on flat ground, was 38km/h. But that's pushing it for the sake of pushing it, my average top speed is just over 30. No lycra, no race bike.

without stopping first

That's normal. Coasting through at low speed uses much less energy than coming to a stop and good bike infrastructure takes that into account. Cars and pedestrians can stop and start easily, bikes, very much not so, so you design intersections, any conflict point, such that bikes merely slow down. The Dutch are brilliant at this with traffic lights which can actually detect who's coming.

My personal approach to cycling is that I never expect anyone to notice me, a result of decades of practice with semi-sensible German bike infrastructure. Yes I'm going to cross on red but noone will have to change their behaviour, react to me in any way. Be like water.

There are a lot of bike fatalities here, but it’s almost always the result of large trucks turning right across bike lanes and flattening somebody they never saw.

Yep don't be there. Even if they're looking out for pedestrians those are slow, you are fast(er), which means that in the time between them looking and them turning you can make it from invisible to the danger zone.

Side note right turns should not be allowed on red, at least not without a sign specifically allowing it at a particular intersection. In 99.9% of cases it's unsafe.

The SPD fraction isn't unified when it comes to this and the misgivings are about "Not becoming a party to the war" not Taurus as such. As delivering weapons does not make anyone a party to anything all they have to do is to stop falling for Putin's psyop.
