do they use f35io.h?

Afair they use a lot of stuff related to the Green Hills toolchain.

Oil has been like that as well. High oil prices don't trigger nearly as much drilling as they used to.

Part of that equation, FWIW, is that certain countries would flood the market with supply to make any new projects suddenly unprofitable.

Which sucks extra bad because if you shut the project down but start it back up you can't just flip a switch. Gotta put together a whole new team and possibly retrain them.

Needs a million upvotes. It costs a large pile of money to design an all-new engine from the ground up that meets modern emissions and is reliable is service for hundreds of thousands of miles. You should be thinking billions of dollars. They only way to make this affordable is to amortize that cost over many many cars of many many years. Sure you will tweak the design here and there for various reasons, but the initial investment to get the first car to a customer is too high to dare start again anytime soon.

Of course with electric cars obviously coming it is questionable if any engine is worth starting today. There isn't much worth doing that a minor tweak to an existing design cannot do - and even if there is something it is questionable if engines will be sold long enough to be worth it. (at least for cars - if you target boats or construction equipment or such maybe - though you will note smaller boats typically just take an existing engine and tweak it because there are not enough small boats sold to be worth a new design)

So much money for an engine or transmission that some companies started collaborating...

GEMA was the collab between Chrysler/Mitsu/Hyundai for an inline 4, and GM/Ford have collaborated on a few transmissions too.

I’ll counter with the jaguar xk engine in production for 43 years.

I assume the American s will be by with a pushrod v8 soon.

whaleofatw2022 · 16 days ago
Actually I'll give a V6 instead:

1961-2008.

That's a series of engines, not a single model. The FIAT FIRE [1] series has been in production for 36 years from 1985 to 2021 and, maybe you wouldn't expect it from FIAT, those engines were reliable.

Meh, GM 3800 had a good 40+ years of production (although some of those years were 3rd party,) I'd take one of those over a FIRE.

> There have to be rules & regulations for how personal data is stored.

Totally agreed.

> There MUST be consequences for data breaches.

Even if you're following those rules and regulations? I think the general idea of malpractice applies here. People do their best, but you can't prevent every unknown. So as long as you're not a complete idiot or acting in bad faith, it's not your fault. Punishing people for a bad actor's actions wouldn't do anything but make it even harder to enter a market.

Preventing data breaches is a lost cause. For one, most everyone's PII is already on the net. Plugging that hole is like patching the Titanic. We're already sunk. What we need is a way to prevent identity theft. Possibly a way to help people more easily recover from it as well. The US has the FDIC in case a bank implodes. We need something like that, but for all my accounts when some guy in Russia takes out five mortgages on my property.

Or, we need to radically rethink PII. We're still using ink signatures on paper to sign for contracts for Pete's sake. I should have to crytographically sign a house mortgage, not make some hand drawn glyph that nobody can read and anybody could fake. Of course, that comes with other problems such as Big Brother having more data about me, but this reply is long enough.

One could still plug holes.

E.x. if the data breached was not critical to legal retention requirements, the penalty is more severe. (Ofc this assumes good definition of what is critical for legal retention).

At the very least it would encourage companies to keep such data less or for shorter times to minimize damage.

It wasn't unusual for larger-scale microcomputers to have bank switching in the late 1970s to the mid-1980s.

RAM chips usually have a "chip enable" pin, you might have chips that have 4k of addresses that are 8 bits wide [1] and fill out the 64k address space by having 16 RAM chips, feeding the least significant 12 bits to the RAM chips and the most 4 bits to a multiplexer that goes to the 16 RAM chips. All of the RAM chips are on the bus but only the one with CE set responds.

The same kind of thinking could be applied to extend the address space past 16 bits, for instance you poke at some hardware register and that determines which chip enable pin get sets, there is really no limit on how much RAM you could attach to an 8-bit machine.

A really advanced bank switching scheme for an 8-bitter was on the TRS-80 Color Computer 3

https://www.chibiakumas.com/6809/coco3.php

where the 64k address space was divided into 8k blocks and which might be backed by 128kB (minimum), 512kB (max from radio shack) or more RAM and you poked into a table which mapped virtual blocks to physical blocks. That wasn't too different from a modern memory management system greatly scaled down with the exception that systems like that rarely if ever had a true "executive" mode so nothing stopped user mode software from poking to change the memory map. The CoCo for instance had a multitasking OS called OS-9 that did muiltitasking like described in the explained if you had the orginal Color Computer, you could get Level II that supported more memory and if you never poked at those registers, some memory protection.

[1] at least you did in 1979.

> 128MB (minimum), 512MB (max from radio shack)

I think you meant KB here but now im also wondering how many MB you -could- actually scale tp and what the overhead would be due to the numbers of banks to switch between...

formerly_proven · 2 months ago
EVs no, but I think some Toyota hybrids (which are of course not even PHEVs) still use NiMH. Toyota tends to be very tight-lipped about their batteries and their sizes (or rather, lack thereof).
whaleofatw2022 · 2 months ago
Early Hybrids used NiMH because Chevron was holding on to a lot of the patents around using Lithium Ion for the purpose IIRC.

Just to be Mr pedantic here, the same mileage means you have a much better vehicle 5 years later. I would add 25-40k extra miles to account for typical mileage added per year
whaleofatw2022 · 2 months ago
Sorry im not following; unless it is a 'special' car, a 2008 car with 120k miles, except accounting for inflation and market dynamics, would be worth less in 2025 with the same mileage. Except of course for the factors I mentioned (as well as inflation)
