I don’t know how I should be the one to come up with a better shorthand if I’m the one being taught and not understanding.

There is no better one. Your hand is the only obvious, also, convenient, piece of equipment you always have at the ready that is capable of clearly and intuitively representing three mutually orthogonal vectors. They also happen to be quite freely orientable in space. There are exactly two distinct ways axes can be constructed in 3d, and your left and right hand naturally show the one or the other, try it: While making fancy fingerguns you can never have all fingers be parallel, if two pairs are parallel then the third is antiparallel. You could use fancy terms like chirality but that literally means handedness.

And if you had tried to come up with something better you'd probably have realised all that.

Does this help? Short of making sure that your fingers actually are mutually orthogonal. The perspective in OP's picture is all fucked up and also not consistent between the hand and arrows.

"x,y,z" of course is an easy order you learned it in primary school, for it to make sense for the physics you need to... do nothing. Order is arbitrary. The handedness is dictated by the signs of the vectors, I guess if you were to flip the sign of some natural constant the whole thing would suddenly be left-handed.

It of course is also not an explanation of why the stuff is like it is. You say handedness plus assigning things to fingers is terrible as a shorthand? Show me something better, then. Meanwhile, generations of graphics programmers could and can be observed holding out their hand like that and rotating it every which way to make sense of what other people preferring different orientations did. Or keeping track of local vs. global transforms. Gotta know where the wheels are even if the car is flipped over.

(and, yes, for some reason there's no 3d software which uses x as the up/down axis. Whether that means that the industry has a bit of sanity left in it I'm not so sure it might be an accident).

Seems so, yes, really shouldn't surprise that the basic idea is known in the UK. Certainly not something you can get for breakfast over there, though, had to survive on nothing but full English because the purpose of their croissants is to spite the French and don't get me started on weetabix. Actually, coming to think of it quark is probably the only thing it'd actually work in.

Not really, no, the texture is never grainy. Micrograins, kinda, but never big lumps. Closest equivalent is Skyr. Consistency between cream cheese and yoghurt, taste more like cottage cheese.

Jet fuel indeed doesn't burn hot enough to melt steel. Forging temperature, OTOH, no issue.

He argued for segregation to remain the law of the land when Brown V BoE occurred, but for ‘separate but equal’ to be actually enforced.

I'm very sure I said nothing about any of that and I'm pretty sure I don't agree with that take. Even if it actually was viable, as in politically possible to have equality while segregation continues, it sounds like ripping of a bandage slowly, very slowly.

Mansplaining isn’t real,

Not a thing I said.

but quick sidenote here is how

That was Eurosplaining. I do that all the time to Yanks and I stand by it.

And yes MLK was rotating in his grave that day. What's your point, here? That it would befit me to want to see black folks being ineffective in their struggle? Is that really where you want to go with this? Want to continue racistjacketing me?

And just for the record I already talked about this with actual BLM organisers. They agreed, it was a missed opportunity, hindsight is 20/20, etc. The issue isn't even lack of institutional knowledge -- the civil rights movement is literally the textbook case on how to stage such things effectively -- the "trouble" (not really, but form this perspective) is that the whole movement gained momentum so quickly that people didn't have time to organise properly.

Co-opting that slogan would have just allowed everyone to brush the conversation under the rug even more quickly than they did.

Co-opting that slogan would have carried on momentum that was broken by getting into a fight with the slogan. It allowed energy to be diverted from opposing specific state structures to opposing a slogan.

This isn't about "oh but white racists came up with it so now it's a bad slogan", it's not about dictionary semantics at all that's not how social movements or political messaging works. If Black people shout "All lives matter" then that's saying "Hey we're people too". It's saying "Not just your lives matter". It's also saying "if your schizophrenic kid got shot by out of control police, go come join us": It allows for a broader movement, overall more solidarity.

You know what's the worst part about this? The right is really good at this kind of stuff. They understand it. They didn't go out saying "Black lives don't matter" or "Fuck N****s", they went out chanting "All lives matter". Because they knew exactly that it was their most effective shot at breaking BLM's momentum, even though they sure as fuck don't care about all lives.

But one group does it far more often.

With "one group" you presumably mean egocentric people in general, and nothing sexed. Because otherwise: Citation or you're a sexist. And with "citation" I mean "controlled for perceptive biases".

Your argument sounds like the “all lives matter” of “black lives matter”.

Plenty of citations for racial bias by US police so no, it really shouldn't. Side note though: The moment the assclowns came up with "all lives matter" the BLM folks should have jumped on it and used it themselves. It's a much more powerful message, and impossible to argue against. With the momentum they had they could easily have drowned out the racists.

You went off the rail when you used "women" and "men" instead of "people".

I'm not exactly sure which one is more frequent, the behaviour itself or the accusation thereof as thought- and conversation-terminating cliche, but both suck donkey ass. OTOH it's not some special grand thing in itself, either, it's plain old failure to relate and communicate.

Ceramics can take plenty of heat, the non-stick isn't stellar but it's there (and probably better or worse depending on manufacturer). And you can reduce tomato sauce in it without killing the patina because there is none. If the anti-stick properties degrade sodium percarbonate should fix that, stripping oil and polymerised oil and everything out of the microstructure. It's basically good ole enamel but with rougher surface. Kind of like those fancy lotus effect sinks.

If your go-to is stainless then I don't think there's real advantages, if you want a second pan then I'd go with iron for actual anti-stick, and do those tomato sauces in stainless.

You are absolutely allowed to remove it, you just have to replace it. The correct thickness is "try to wipe it all off with kitchen tissue", it really shouldn't be a grease hazard to clothes.

Also washing up liquid should do the trick.

Eggs pretty much work like meat when it comes to stickiness, just with an even tighter window when it comes to right temperature and it's even more important to let the thing be for a while before attempting to move it.

Also, yes, scraping. I use a burger flipper spatula which practically has a knife edge at the front. Ideally though things should be moving when you shake the pan, that is, loosen on their own.

 

Videogames are being destroyed! Most video games work indefinitely, but a growing number are designed to stop working as soon as publishers end support. This effectively robs customers, destroys games as an artform, and is unnecessary. Our movement seeks to pass new law in the EU to put an end to this practice. Our proposal would do the following:

  • Require video games sold to remain in a working state when support ends.
  • Require no connections to the publisher after support ends.
  • Not interfere with any business practices while a game is still being supported.

For all your boycotting needs. I'm sure there's some mods caught in lemmy.ml's top 10 that are perfectly upstanding and reasonable people, my condolences for the cross-fire.

  1. [email protected] and [email protected]. Or of course communities that rule.
  2. [email protected]
  3. [email protected]. Quite small, plenty of more specific ones available. Also linux is inescapable on lemmy anyway :)
  4. [email protected]
  5. [email protected]
  6. [email protected] and maybe [email protected], lemmy.one itself seems to be up in the air. [email protected] says [email protected]. They really seem to be hiding even from another, those tinfoil hats :)
  7. [email protected]
  8. Seems like [email protected] and [email protected], various smaller comic-specifc communities as well as [email protected]
  9. [email protected]
  10. [email protected]

(Out of the loop? Here's a thread on lemmy.ml mods and their questionable behaviour)

 

A new paper suggests diminishing returns from larger and larger generative AI models. Dr Mike Pound discusses.

The Paper (No "Zero-Shot" Without Exponential Data): https://arxiv.org/abs/2404.04125

 

We interview half a dozen artillerymen, medics, and others, in this exploration of the life of artillerymen in the most intensive artillery war on the planet, the Russian invasion of Ukraine. The interviews are extensive and unfiltered. They cover topics like living on the front, cluster munitions, living underground, the mental health of soldiers, alienation from civilian life, what motivates them to fight, surviving in the winter, what they do for fun, and many more stories.

 

This is a long one, flipping a common understanding of things on its head: Instead of seeing certain things e.g. tankies believe as Russian-caused disinformation (most prominently, colour revolution theory) it traces that stuff back to Lyndon LaRouche and chalks up what Russia is doing to KGB-brains swallowing an American conspiracy theory as truth: It's not that Russia has master-minded some disinformation campaign against the orange revolution, Maidan etc. to justify the invasion, the Siloviki actually believe that shit.

If you ask me that makes a jading amount of sense.

 

In this video, I measure a wave of electricity traveling down a wire, and answer the question - how does electricity know where to go? How does "electricity" "decide" where electrons should be moving in wires, and how long does that process take? Spoiler alert - very fast!

I've been very excited about this project for a while - it was a lot of work to figure out a reliable way to make these measurements, but I've learned SO much by actually watching waves travel down wires, and I hope you do too!

 

This is from the 37th Chaos Communication Congress, still ongoing y'all might find other things of interests there, e.g. sticking with looking at stars the talk about the Extremely Large Telescope. Congress schedule, live streams, relive and released videos (i.e. final cuts not the automatic relive stuff which is often quite iffy)

Talk blurb:

The Solar System has had 8 planets ever since Pluto was excluded in 2006. This has made a lot of people very angry and been widely regarded as a bad move. But did you know Neptune was discovered as the 12th planet? Or that, 80 years before Star Trek, astronomers seriously suspected a planet called Vulcan near the Sun? This talk will take you through centuries of struggling with the question: Do you even planet?!

In antiquity, scientists counted the 7 classical planets: the Moon, Mercury, Venus, the Sun, Mars, Jupiter and Saturn – but their model of the universe was wrong. Two thousand years later, a new model was introduced. It was less wrong, and it brought the number of planets down to 6: Mercury, Venus, Earth, Mars, Jupiter, Saturn. Since then, it's been a roller coaster ride of planet discoveries and dismissals.

In this talk, we stagger through the smoke and mirrors of scientific history. We meet old friends like Uranus and Neptune, forgotten lovers like Ceres, Psyche and Eros, fallen celebrities like Pluto, regicidal interlopers like Eris and Makemake as well as mysterious strangers like Vulcan, Planet X and Planet Nine.

Find out how science has been tricked by its own vanity, been hampered by too little (or too much!) imagination, and how human drama can make a soap opera out of a question as simple as: How Many Planets in Our Solar System?

 

~~Astronomers~~Engineers^1^ presenting at the 37th Chaos Communication Congress for a general but technical audience. The congress is still going on in case you're interested, lots of interesting stuff there and don't be afraid of German talks there's real-time dubbing.

Talk blurb:

The Extremely Large Telescope (ELT) is currently under construction in the Atacama desert in northern Chile by the European Southern Observatory (ESO). With a primary mirror aperture of 39m, it will be the largest optical telescope on earth. We will briefly introduce the history and mission of ESO and explain how a modern optical telescope works.

The European Southern Observatory (ESO) is an intergovernmental organisation founded in 1962 and is based in Garching bei München. It develops, builds and operates ground-based telescopes to enable astronomical research in the southern hemisphere and to foster cooperation in the international astronomical community. In 2012 the ESO Council approved the Extremely Large Telescope (ELT) programme and its construction is scheduled for completion in 2028. The 39m primary mirror will make the ELT the largest optical telescope at that time.

It will be located on the top of Cerro Armazones, a ~3000m high mountain in the Atacama desert in Chile. This site provides ideal optical conditions, but also comes with logistical and engineering challenges.

We will walk you through the telescope and along the optical path to the instruments and explain some of the technologies involved to push the boundaries of ground-based optical astronomy.


^1^ Oh boy the "what is it good for" question got them swimming. "I'm not an Astronomer -- Science, I guess? Looking at things?" :)

 

Link to talks schedule, times are CET (deal with it)

Streams will show up here and final recordings here. There's generally also rough-cut recordings posted automatically after a talk is over, don't have a link for that yet.

Oh and for completeness' sake the congress' web page.
