All this because nobody wants to change the ELF loader to better isolate dependencies of binaries

I think it's more because Linux OS developers have never bothered to move away from Unix's "all apps get mixed together at absolute locations" filesystem model.

If apps were like on Mac - self-contained directories that can be installed at any path - then Docker would probably be a footnote.

According to the car, the stability control system wasn't working. Cause? Obviously a broken fuel injector. The stability control system talks to the engine ECU to control the torque if there is a lack of traction - it is notified of this by the ABS computer. Broken Injector=No ability to manage torque, hence traction control warning. Sitting here now, that makes perfect sense. In horizontal Scottish rain - less so!

My car has a button for traction control. If it’s not working I would expect it to turn itself off and ding, not just halt the vehicle.

A bad fuel injector should usually be a reason to stop driving. Depending on the type of damage it would likely damage the piston and/or cylinder fairly quickly if you attempted to keep running it.

You know what this car needs? Kubernetes.

Lol. Reminded me of this - https://youtu.be/cfTIjuW6SWM Fwiw - I am a kubernetes fan. Just not in cars.

If you're a k8s fan but don't consider it reliable enough to do anything even next to but independent from safety critical systems then that's not exactly a glowing recommendation.

But what cash grabbing opportunity would the dealer have in that case?

I'm all for improvements to pod startup times etc, but the general idea of putting more software into cars is not that appealing. I recently broke down in the highlands of Scotland in a fairly new car with the family - it was a horrible experience. It was made worse by the fact that there was nobody close that had a clue what to do with the car. The breakdown service arrived promptly, plugged the diagnostic tool into…

It's also a liability issue. If a company allows tinkering with the software in the car it opens itself up to massive lawsuits. If we have a right to repair here, we also need to see how to handle liability here. If you flash your own software on the motor controller and subsequently mow through a group of people because you forgot to do a plausibility check on the accelerator pedal value who takes responsibility the…

Lol, this is absolute funny, every example you came up with has already been there for years. Aren't cars being modded every day, ECU tuning, engine mods, etc? Go ahead sue the company, companies aren't some innocent babies, they can afford to quickly dismiss the claim by just pointing towards the mod. Auto Companies have never been held liable for a car that has been modded. Does it waste money to be sued? Yes! But…

"ECU tuning" is just fiddling about with some values in a lookup table, though.

The EPA has suggested they will hold companies liable in the future. It hasn't happened yet, but they are hinting. If it is just one hobbyist they don't care, but there is a whole industry of chip your diesel truck and those chips clearly increase pollution. A modern diesel truck doesn't emit black smoke, but a large % of the diesel trucks you see are "rolling coal" which is a sure sign that someone has disabled the…

Not disabled the emissions controls, but deliberately remapped it to grossly overfuel at large throttle settings.

Why people want to trade off power for a big cloud of black smoke is beyond me, but there we are. If they want to get 50bhp from a nine litre engine, that's their concern.

More software is fine IMO. More software on critical path ain't. Have the ECU only do the engine thing. Have the AC control just do AC control. Decouple dependencies and make it as simple as possible. Old cars already do it. Blinker switch send signal directly to light controller, not to some central box deciding what it should do with it. If something needs config in addition to control signals, have it keep it own…

You know what this car needs? Kubernetes.

Agree. I am not buying any car not running all software components as Spring Boot micro services in kubernetes cluster as a standard cloud native service.

If this setup can run my 95% uptime enterprise apps, I am sure as hell it can run my car too.

I know you are joking but it’s actually not the worst thing in the world.

Can't wait to have to restart a kubernetes cluster to get sensor metrics from the engine to start again.

You'll need to replace your kubernator!
