I’ve working in automotive since it was only wires and never saw that (or noticed it) happening specially since usually body and powertrain work on separate buses tied through a gateway, the crazy stuff happens when people start treating the bus (specially the higher speed ones) like a 12v line or worst.

I didn't experience that but the commercial stuff I worked on was in a heavy industry on J1939, and our bus was isolated from the vehicle to some regard.

Then the stuff I mess with at home is 90s era CAN and it's basically all diagnostics, actually I think these particular cars don't do any control over the bus.

Every single hardware subsystem adds lag. Double buffering adds a frame of lag; some do triple-buffering. USB adds ~8ms worse-case. LCD TVs add their own multi-frame lag-inducing processing, but even the ones that don't have to load the entire frame before any of it shows, which can be a substantial fraction of the time between frames.

Those old systems were "racing the beam", generating every pixel as it was being displayed. Minimum lag was microseconds. With LCDs you can't get under milliseconds. Luckily human visual perception isn't /that/ great so single-digit milliseconds could be as instantaneous, if you run at 100 Hz without double-buffering (is that even possible anymore!?) and use a low-latency keyboard (IIRC you can schedule more frequent USB frames at higher speeds) and only debounce on key release.

I believe this is kind of survivor-bias. It's very rare that RTOSes have to handle allocating GBs of data, or creating thousands of processes. I think if current RTOSes run the same application, there would be no noticeable difference compared to mainstream OS(Could be even worse because the OS is not designed for that kind of usecases)

>what is my point? well, i think a web stack ran under an RTOS (and sized appropriately) might be a much more pleasurable experience. Get rid of all those lags, and intermittent hangs and calls for more GB of memory.

... it's not the OS that's source of majority of lag

Click around in this demo https://tracy.nereid.pl/ Note how basically any lag added is just some fancy animations in places and most of everything changes near instantly on user interaction (with biggest "lag" being acting on mouse key release as is tradition, not click, for some stuff like buttons).

This is still just browser, but running code and displaying it directly instead of going thru all the JS and DOM mess

Great point, if the only constant is change, then philosophy should follow (or lead).

> optimal Nash equilibrium where both offer and demand are balanced

This roughly translates to "optimal utopian society which cannot be criticised in any way" right? Right??

Many intellectuals have this problem. They make interesting, precise statements under specific assumptions, but they get interpreted in all kinds of directions.

When they push back against certain narratives and extrapolations they usually don’t succeed, because the same mechanism applies here as well.

The only thing they can do about it, is throwing around ashtrays.

So it will reach equilibrium unless literally anything disrupts that equilibrium. Got it.

An "autonomous market with enough agents" is carrying a lot of weight there, like "rational actors" and "as sample size goes to infinity'.

The problem with this is that "breaking the Nash equilibrium momentarily" is a spherical cow.

"Momentarily" can mean years or even decades, and millions of people can suffer or die as a result.

Governament contracts are very restricted behind layers of certifications and authorizations.

For example, you can't freely produce missiles and have it in wallmart where "the governament" purchase at shelf price.

> The government contractors (private enterprises) are usually tasked with building stuff

Ah yes, situation where the government makes a plan and then hands it to the one (1) qualified defense contractor whose facilities are build in swing states to benefit specific congressional campaigns is completely different from central planning.

You should read up on Yanis Varoufakis' history and just how bad his solution for Greece went. That will explain the extreme amounts of anger on both his side, the side of Greeks and the side of the EU and worldwide financial community (and the EU itself used to be an industry cartel, so you can guess how much every government institution in the EU aligns with the worldwide financial community). This guy will never be allowed to do anything remotely serious in economics ever again, and he knows it very well. His Diem24 project is failing, and he knows that too. He feels the ECB, specifically Mario Draghi, Jeroen Dijsselbloem and Christine Lagarde are responsible for this downfall and talks about them in a way that makes you say "he can't be allowed near them. Seriously. Call the police". But in the constant tragedy of his life: He's probably right they caused his downfall.

He caused a MAJOR issue for Greece that still affects everyone in his country today, after reassuring people for 2+ years it was never going to happen: https://en.wikipedia.org/wiki/Greek_government-debt_crisis

(He'd kill me for saying this but he was lying back then too. He was trying to pull a Thatcher (I could compare him to someone else that did the same a long time ago but ... let's just say if you know you know). He was trying to double Greece's public debt by lying to everyone about what he was doing. He failed, and then started threatening, and when his threats didn't work, he got fired by Greece's prime minister, his oldest friend. It ended the friendship. He lost. And he's not a good enough sport to accept that he lost, frankly he got caught and couldn't talk his way out of it. This, despite the fact that he was finance minister, and so will be paid, very well I might add, for the rest of his life despite what he did, and despite the fact that every Greek today is still paying the price for what he did)

Oh and he's pro-Russia. All Russia wants in Ukraine, according to Yanis, is help the European poor. More detailed he is of the opinion that the current course of action of the EU will lead to a war with Russia, in which a lot of European poor will be forced to fight in an actual war, facing bullets and bombs in trenches. This could be avoided by giving Ukraine and the Baltics to Russia. In the repeating tragedy of Yanis Varoufakis' life, I have to say, yet again: he may be right (I just strongly disagree that offering Ukraine and the Baltics up to Russia is an acceptable solution to this problem, and in any case, this is neither his, nor my choice to make)

He does not live in Greece, his own country, he lives in the UK, making the case for Russia.

And I get it, his life has become this recurring tragedy. His father was a victim of a rightist dictatorship in Greece, and he was imprisoned and tortured for that, as well as losing his job, living in poverty for a very long time (yes, Greece was an extreme right dictatorship not that long ago, really, go look it up). Yanis Varoufakis himself became the victim of a cabal of laissez-faire very, very rich people who destroyed his career right at the peak of everything he achieved. He has been the victim of one or another form of extreme-right policy (in the sense of laissez-faire parties that capture governments) since he was 4 years old, right up to today. Over 60 years his life was sabotaged in 1000 different ways, some very direct. And, sadly, I agree with his "extreme-right" enemies: he can never be in allowed near any position of power ever again because of this, which isn't even his fault. (extreme-right according to him, I would refer to his enemies as "the status quo", and point out it's working pretty well for everyone)

Economics is propaganda. It’s not an empiracle science, and it’s claims are mostly used to promote ideologies consistent with government policy or the ideology of powerful individuals with the surplus’s wealth available to pay someone to build a quantitative defense of said ideology. What else would you call it?
