Spectre / Meltdown

Once written software costs nothing more than a ROM And in fact the reason even the cheapest cars now have electric windows is that it is lighter and cheaper to do it that way.

Marketing is not as all encompassing as its made out to be and those who are susceptible will always be susceptible. You cant fix lazy and stupid and vain. 'Useful idiots' are born every minute, and there is nothing to be done. They will always be gulled by everybody.
You are an excellent example. You argue for state oversight but you haven't thought it through. The state can be bought and in fact it is. You really don't want to know who owns the Democrat party.
They *are* the people they warned you about...

Be very careful of this. Fast chargers for nickel cells use the delta peak detection - a fully charged nickel cell will show a DROP in peak voltage as it reaches full charge. This is detced to switch the fast charger off.
The drop is far smaller on NiMH and sometimes not enough to switch the charger off..not good.

Exactly the same observations here. It started like 15y ago even before the smart phones came out, which only escalated and accelerated the process.
Few months ago I saw a lecture by one professor who was talking about the negative effects of computers and technologies on the mind of children. He said despite there are no large studies. The smaller studies done so far are devastating. We were confronted with smart phones when we were already grown and our brains were already developed. No one knows what happens to a brain that is developing. For me however the problem is deeper as it roots into the family and the change of the paradigm in the schools. Humanities are about 90% of left thinkers. Ideologies rule now in schools universities, social media - no place for logic. If you do not agree, you are "Trump supporter" or "fashist". On top there is no normal communication at home and with the next generation the loop closes tighter. I've honestly been thinking to learn Russian and to emigrate to Russia :D When I was there in 2007 I saw young people reading books in the subway. I plan to go there again to see how it looks like 15y later. My conclusion is that in the west we have a problem imposed by (neo)liberals, who most often do not have children but dogs. It is not the only one reason, but as it was said before the people make their choices and decide how the society works.

There have always been a lot of people like this, they used to mostly get swept up by the dominant religion and told what to think that way. For a short while I think the dominant TV fashions may have taken over the role (viz MTV generation). These days the influences are more random, I'm not sure whether that's a good thing or not but it's what is happening.

I should have popped the battery holder out before I wrote that: my HP-21 is actually running on Maplins Hybrid AAA cells.
I don't know the exact chemistry, but its possibly a riff on NiMH.
Its certainly not NiMH as we used to know it because it holds charge at least as well as NiCD did, while NiMH was famous for self-discharge: the ICG flight logger in my glider uses a pair of AA size NiMH and *must* be recharged every 1.5 - 2 months when its in use during the winter. Otherwise the batteries will self-discharge and destroy themselves.

There is a low self-discharge variant of NiMH with slightly lower capacity and rated retention of around 80% over a year. In the shops they get advertised as pre-charged or similar. I've been using them long enough to wear some of them out (it took several years).

NiMh has certainly improved: modern cells will do a year or so

I've been trying to find the word for that. As I understand it, fascism is authoritarian control based on fear. Left wing used to mean humane, reasoned fairness; or so I thought. So what is it when rich, spoiled kids claim to love Marxism, but don't expect to give away any of their stuff to poor people? What is it when the left wing becomes so extreme that it's a totalitarian movement.
Example: The restaurant goers in DC last week who were threatened and harassed for not raising their fist for BLM. Like Nazi Germany. Or maybe Salem circa 1690? I don't understand political ideologies well enough to know how to characterize this stuff. And aside from Jordan Peterson and Camille Paglia, I haven't seen anyone with the conviction to assess the emperor's new religion.

State oversight? Is that what you call it when we have regulations banning DDT on peaches, arsenic in vitamins, or faulty car parts made of junk metal? Or maybe regulations stating obvious things, like that TV makers and cable companies don't have a right to record you through your TV set? I thought "civilization" might be a better description.
| The state can be bought and in fact it is. | You really don't want to know who owns the Democrat party. |
And therefore we should throw out the baby and even the bathroom with the bath water? There's no sense in continuing to argue this same point if you don't get it. You avoid specific issues to dismiss everything as corruption and human stupidity. Smugness as a drug.
I don't think you want to get it. It's easier to smugly point out corruption than to step up and represent decency. But you do have that option. You could stop your hissing accusations for a moment and just try to propagate decency. Maybe start small. Help a hairdresser set up her email, without telling her she's an idiot. Then you could progress to doctors, lawyers and Indian chiefs. You might find they're not all moprons simply because they don't have an aptitude for computers. :)

There are many, but Google changed the algorithms, so that you can not find them. Today you must know the names. Some 5 or 7y ago you could open youtube and it would offer relevant content based on the information they gather for you. It was a fair trade off. Now it is only spying and selling your data without giving anything in exchange. Especially when it comes to anti main stream thought.

No fancy end-point detection in the chargers for that Wahl shaver--just a transformer (as measured by wall-wart weight), so no big difference in behavior between the cell types. IIUC, a lot of NiMH cells contain a catalyst that shunts off excess charge. It's been at least a few years of charging about every 20 days, so I'm guessing my cell (purchased from Mouser) has the catalyst.

Oh the nativity! Modern ECU software is not in ROM, and will be modified and re-flashed many times the lifetime of a car. Particularly when cheat modes need to be removed.
But even more importantly it eliminates the need to safety test a second mechanism for each car design.

Flash memory or ROM, the point remains. Its cheap once you have written it.In fact is cheaper when you have flash rather than EEPROM or fusible ROM

doesn't what? How expensive is linux, really? How can an internet of things and so many toy manufacturers push product out sub $10 if the firmware is billions? I can buy a controller for a sensorless brushless motor that has an ARM chip and some pretty complex software in it for about $10.
It is actually cheaper than a *decent* commutator and carbon brush system
That is why manufacturers are now using them ...
How can a pattern cost money? software is essentially zero cost to implement once it's been written.

Software is full of bugs. In a safety- and/or security-critical context, you can?t just ignore them, you need to find them (preferrably before someone else does), then recertify and redeploy the fixed software.
Certification is a moving target, at least in my industry, I don?t know about automotive. Same issues as above.
Security is a moving target; attacks keep getting better. Same issues again.
And that?s before getting into changing customer needs, competitive challenges, rebranding, ...
