See, when you're talking about rendering, you're saying millions. And even then you're talking about millions of elements in a physical simulation, all interacting with each other etc.

The browser struggles to display even a few hundred elements. You can't even animate something efficiently if that touches even the smallest part of a layout.

I understand your point, but for the most part memory-safety features and speed of execution run contrary to one another.

Garbage collection and bounds checking is big sticking point for systems / high performance programming, and to an extent real-time programming.

The same Han character can have wildly different pronunciations even in a single language (being a logogram, they represent a word and not a sound). KS X 1001, the primary Korean character set, even duplicated same characters according to their readings so that they can be almost [1] correctly converted back to Hangul.

> Even the European Union, which has been subjected to quantitative easing policies from around a whole decade and thus has been seeing their central banks print money like crazy, at most only complains about low inflation and mild economic stagnation.

The part with print money like crazy is absolutely true.
The claim that there's low inflation in Europe, is absolutely false.
Official inflation numbers are relatively low only because real estate and other things are arbitrarily excluded from cpi.
It's always astounding to me how people can pretend as if rising real estate prices did somehow not trickle down to rents and thus effectively all everyday purchases, people make.

The world is full of zero-sum games whose existence people often deny ... just because many of them are long and complex and interconnected chains of interactions which means they are lots of work to describe accurately doesn't mean they're not there.

Actually, it is "pushes-flow-down-so-goes-up".

You remember? Action requires opposite and equal reaction?

Plane is (mostly) not a rocket and so to be able to fly it has to act on something and the only something up there is air. If the plane is being lifted it means a bunch of air needs to be pushed/dragged down.

Helicopter is a better way to visualize it.

Now, in a plane, once that air is pushed/dragged down it immediately starts doing funky things like vortices and so on, but at least initially the air is being pushed/dragged down.

I write "pushed/dragged down" because the air is deflected on both sides of the wing. On the low pressure side of the wing (hopefully for most people this is the upper side) it is being deflected by creating low pressure in a laminar flow. If that laminar low pressure flow state is lost and instead we get turbulences, those turbulences are really bad at inducing the air to go down. We say that "it has stalled".

EDIT:

The only way for something to stay up is to push off something. When you stay on the ground you push off the ground but when you are up there you have to push something else even to just stay at an altitude.

Wings, turbines, rocket engines, propellers, barn doors, these are just different ways to accomplish the same task -- push air (and very infrequently some other material) downwards.

A plane is different from a rocket in that the material is mostly air (and very tiny amount of fuel) and main mechanism of pushing it are wings and air breathing engines/turbines.

Some planes can have so much power that their main pushing mechanism is engine exhaust and additional air sped up by the turbine.

But most planes have engines that do not produce anywhere near what is needed to stay up this way. These planes use the engines to push (mostly) forward (there is slight downwards vector due to engine exhaust being in line with the plane body but AoA positive). These planes rely on air stream being deflected downwards as seen by the plane to be economical.
If energy is not limitation, you can do almost anything you want, like making diamond, water and microprocessors from grass clippings. The water we currently use in the world IS coming in from air, it's called rain. There are rivers and lakes full of it. Precipitating it would just make it rain a little less.

>services providing reverse chronological feeds should be considered platforms while services providing algorithmic feeds should be considered publishers

A reverse chronological feed is no more or less algorithmic than any other - any sort requires an algorithm. You're just criminalizing algorithmic complexity, which is insane. There's no reason the same n items in a list should expose a site owner to different degrees of legal liability because they're sorted one way versus another.

What about cases when the user can choose a different sort? Is a company liable based on whether or not a user decided they wanted to see content in anything other than strict chronological order? Is Twitter publishing or promoting content as soon as users tag it? Does sorting by karma make Hacker News a "publisher" of content? Do downvotes and flags count as "promotion" of the downvoted content, or all non-downvoted content?
Several chem processes use natural gas as the feedstock and some of the secondary byproducts also have industrial importance.

As an example, the UK needed high-level government attention to a CO2 shortage that was crippling the meat production process. Natural gas went into fertilizer production and the CO2 byproduct was used by meat processing plants for animal slaughter, when gas prices spiked fertilizer production stopped and the supply of CO2 dried up. The abattoirs stopped accepting animals and meat production halted, but animals keep growing (and eating) so you have a weird bump in meat production where a lot of animals were killed early in anticipation of no processing capacity and that is leading to some weird shortages and price spikes.

I am sure there are other examples of this, but much like the knock-on effects of disruptions in chip production supply chain, the spiking gas prices are revealing some dependencies that had previously been rather invisible to the rest of us.
Look, I'd just kill for a generic Set, tbh.

You can't have 'ı' ≡ lc( uc 'ı' ) unless you already know you are processing Turkish ... completely unnecessary complication.

> The second page of the article seems to address this and calls it an incorrect lift theory.

If it does, it's wrong. Edit: Now that I have read it, I would have to disagree with you. The article only references the Bernoulli pressure arguments, it does not mention Newton's third law or airflow circulation.

> The real details of how an object generates lift are very complex and do not lend themselves to simplification.

There is no scientific contention about flight. Nobody is currently publishing papers on this topic ("journal of fluid mechanics" if you are interested), it was well understood in the previous century. Newton's third law explains at a high level how object fly. Yes you can dig into the details of fluid motion, turbulent flow, boundary layers etc, but this does not detract from the high-level picture.
I started with BASIC, and never liked Pascal at all (I eventually took to C like a duck to water), but it must have something going for it as a systems language because the original Mac OS was largely written in Pascal (I’m not sure of the balance between Pascal and assembly).

I wonder if we’d have fewer memory-related bugs now if the industry had standardised on Pascal strings (length prefix) rather than C strings (null-terminated)?
I believe they use Phytium chips. Phytium is a Chinese chip designer which specialize in HPC using ARM cores.
(Please note ... we are not in disagreement, but I wanted to address this)

Asking how 'planes fly upside-down and putting one's theory to the test in this thought experiment is useful, but it doesn't refute the "downwash" theory. If you have a wing at an appropriate angle of attack, even if upside-down, then provided the flow remains attached, it (the flow) can still be deflected downwards.

If the wing is reasonably asymmetrical then the angle of attack needs to be large, which makes it more likely that the flow will become detached, so we deduce that a 'plane designed to fly upside-down needs to have symmetrical, or near symmetrical, aerofoil profiles ... which they do.

So the downwash theory is not refuted by the "upside-down" question.

(Please note: All that notwithstanding, the unadorned downwash theory is not the complete explanation of how lift is generated)

But, the data is more important than the OS here. And the filesystem is a variant of ext4 and there's some instructions floating around on how to mount drives on an external standard Linux machine to recover said data in the event of a disaster.

No, this is wrong.

First of all, rockets are no exception. Just throwing things backwards will make the object fall to the ground, no matter how hard it pushes.

It is indeed the air that pushes the wing up, but you have to ask yourself why the wing would need to be shaped in a certain way if it's merely deflection. If it was that, you could just have flat boards at an angle and be done with it.

Vorticity has to come into the explanation, and explains both the points further up.

> Yes there is

No, I don't. I was asking for a list of authorities that you would consider authoritative (which invariably will be subjective, but would be interesting nonetheless).

> You could also flip The argument on its head and say why should every committee that throws a specification up be considered a standards authority when half the time specifications are incomplete, contradict other specifications or flat out don’t work.

Oh sure, specifications always suck™. But that is unfortunately quite independent from the organisation, happens all the time with ISO standards, IETF RFCs, or whatever you would consider "recognised" bodies.

> I have no interest to waste any more time explaining the difference between a standard and a specification to people who are unwilling to consider there might be a difference.

You haven't explained anything. All you have been saying in this thread is "I don't recognise the Reproducible Builds project as a standards authority, because I only believe in my personal list of authorities that I won't reveal".

The point is, a standard does not become a standard because it is published by a "competent authority". A standard becomes a standard when people in the respective field converge on using it.

And yes, there are of course certain fields where this convergence can be enforced e.g. through local law, professional associations etc. However, software development is generally not one of these fields: who will reprimand you if you write a C compiler that does not follow ISO/IEC 9899, or in this case one that does not respect SOURCE_DATE_EPOCH?
That's a very bold statement, so I'm compelled to ask:

In the light of evidence that conflicts with your statement, why should we believe you?

In particular, we know that fluid flows faster over the upper surface[0], so we know from Bernoulli that the pressure over the upper surface must be lower. That appears not to be included in, or covered by your statement, which suggests that your claim that "It is really that simple" is wrong.

Well thank you for stats 101 but what I was trying to ask was that if this level of confidence promising within medical/pharma field - i.e. do we have stats on studies that said something like out of the 767 or whatever studies that claimed a drug sounded promising because it was associated with 5% outcome improvement - 90% resulted in long term commercial success of the drug.

I mean take Remdesivir - https://www.nejm.org/doi/full/10.1056/nejmoa2007764 - statistically significant yet some other studies found it had no benefits. At least I don't think it was a slam dunk or promising in real life as day the vaccines.

I think "This would dial the entire Internet ecosystem back to look a lot more like the 1990s" probably understates it, to be honest. In the 1990s, heavy USENET users, say, would generally use tools which highlighted posts from users they were interested in, downranked or hid posts from users they were specifically _not_ interested in, and similar. This made USENET usable (for a while).

NNTP clients generally worked by just downloading the whole group, so this could be done client side. With the scale of modern internet services, however, you're not going to be downloading the whole day's twitter content and doing client-side filtering, so you'd need to provide your filtering list to the provider. At that point, you have a friends list, and on a naive reading this might be a problem.
