I think there's a difference here on viable product vs practical product.

The human form is so powerful in a labor setting not because the human form is the absolute best, it's because a person can be autonomous with very little direction. With robots you have to meticulously program them for every single movement and timing, and coordinating the dozens of joints a humanoid robot would have just isn't worth the practical effort. Far cheaper, easier, and faster to build a robot with the exact number of joints you need for the job at hand.

It's because y'all lie about how many lakes you have, you dishonest bastards. 15k != 10k

In all seriousness going to LEO gets the job done the vast majority of the time, medium and high earth orbit have very few use cases with the exception of geostationary which SpaceX has gone to.

Going to the moon is very energy intensive and you don't get a ton of benefit for it so there's no real point to going there. Apollo was a jobs program and a dick waving contest with Soviet Russia to prove who could put the biggest nuke anywhere on Earth. Going to the moon has very little scientific/practical value outside of political stunts which Apollo and Artemis programs definitely are

A plantain pork meatball legit sounds amazing.

Crush/grind the plantain? Mix with ground pork, salt, pepper, cumin, garlic, pan fry and serve with a glaze? I think that might just work and I kind want to get it

This is not the magic of buying two of them

My theory and point was that by thinking about that computer as a console, in the average consumer mindset it should be priced like a console. From a pure hardware product perspective there is no difference

Valve is thinking about it as a computer, and has stated they intend to price it like one and not like a traditional console

I think the problem is Valve lost control of the messaging, which led to bad expectations.

At least in the US, a computer hooked up to a TV to play games means it's a "console" and not a computer. Maybe we can blame Nintendo back in the 80s for going out of their way to avoid calling the NES a computer (despite it's name in Japan being Famicom, Family Computer), but the distinction exists today despite technologically no real difference. You know this, I know this, Valve knows this. So Valve wants to make a computer you hook up to your TV so they can get you to use ~~their money printing machine~~ Steam in the living room too.

If you read Valve's marketing material on the Steam Machine, they don't use the word "console" once. It's always either by name or the terms PC, computer, or system. They likely don't mention the word "console" because to date, video game consoles follow a different business model, one where the model subsidizes the shit out of the hardware and then make money on the back end with game sales/licensing.

Current "console" hardware starts in the <$500 price bracket, and with so much third party media marketing calling the Steam Machine a console, that got people's mind set on pricing expectations of that market.

Can't you read? It clearly says 11 tons

Yeah, US and JDM cars are predominantly gasoline engines. Engine start current draw is similar between the two engine architectures but gasoline engines with their spark plugs would certainly cause noise on the ground line during normal operation which is probably the biggest reason for the dedicated ground line. The digital electronics would also be sitting behind a down regulator that I'd be willing to bet isolates the ground as well.

I still lean towards the original topics failure mode being electrical based not software. Software faults tend to be highly repeatable and almost always persist across full power drains since, assuming no underlying electrical issues exist, computers execute software instructions perfectly every time. Given the exact same set of inputs and the exact same timing, they'll get back to the same state. And that would have been happening since the factory.

Degraded electronics could be feeding new or unexpected inputs into the computers that trigger different software state transitions that then lead to unintended or unexpected behavior, but things would have to be going pretty off the rails for the system to pass all of its built in tests and not realize something has gone wrong.

Another possibility is the mechanic found loose harnessing, connectors, did a few different unplug/plug cycles and then only told you about the battery.

Not necessarily

In electrical engineering floating just means there is nothing forcing a particular conductor one way or another. All a battery does is try and force its two terminals to be ~12V apart, what happens coming off the battery terminals is a different story. If you had a bad connection to the terminals a resistance could have been there, itself driving a voltage difference depending on the current passing through it.

Interesting that your car routes all return through the chassis, I've never seen that before. Admittedly I've only ever worked on US or JDM cars, but the ones I've worked with typically have separate return lines for the electronics, a dedicated thick one for the engine and then the engine is what connects the chassis to battery return.

No disappointment, just a fun interesting problem and learned something about European cars.

That's not software, that's almost certainly purely electrical. More specifically, disconnected/floating ground/return lines. Car computers need 0 Volts to look like 0 Volts and 12V to look like 12V, but floating grounds can cause 0 to look like -4 and 12 to look like 20.

Strong chance that the battery terminal connections were corroded or not tightened down enough to get good contact and that by disconnecting/reconnecting the new connections were better.

Let me ask you this

Take a CPU designed in the last 80 years. Ask it to divide integer 1 by integer 2. Explain to me why the CPU hands back 0 and not 0.5.

Technical solutions do have fundamental limitations to them that cannot be overcome. That scenario plays out all the time. We didn't overcome integer division by brute force, we acknowledged that the approach of having computers use integers for numbers is flawed and came up with a bunch of possible solutions until finally settling on IEEE754 and even then it still doesn't handle all math correctly.

Blindly saying such issues can be overcome is, imho, the truly stupid statement
