Honestly, I feel like German cars have an undeserved reputation for quality. German cars are superficially well built, quite fast, and make satisfying thunks when you close the doors. However, they are fairly unreliable, sensitive, and when they do fail, cost a lot to repair. I'll take a Japanese car any day, however, Hyundai, Volvo, Skoda, Kia, Peugeot and Ford are also better engineered than most German cars nowada…

Skodas are just previous gen Volkswagens btw

My Skoda is the most boring, unsurprising, uninteresting and reliable car I every driven. I love it.

I'm sad they've stopped making functional-first cars like the Yeti, and now just do versions of VW models. I think Dacia might have taken up the mantle of no-frills and reliable though.

Preempt RT does give guarantees in the sense that unbounded latency is a bug and theoretical maximum latency bounds are known (see [0]). It is neither certifiable nor formally proven, but it's good enough for almost anything that isn't safety-critical. For the things that do require functional safety, you can use AGL and other hypervisor architectures that partition the critical and non-critical tasks with a few more…

Very interesting. Thanks for the link to the paper. Isn't the provided paper "just" about the scheduler? Eventually, I would have to output some data, e.g. on the CAN bus with socketcan through the network stack. This is probably a huge amount of code for which worst-case-execution-times are probably hard to get. Does AGL mean automotive grade linux? What would be other hypervisors?

The time it takes to put things on a physical bus will depend on your hardware and can be bounded, but this isn't the guarantee you're getting from any RTOS.

The main thing the "RT" in RTOS guarantees is that the OS will return control back to you in a defined amount of time as soon as you're ready to run. You're still responsible for ensuring all of the other system requirements for bounded latency are fulfilled, like hardware that doesn't introduce unbounded latencies the OS can't control (surprisingly difficult with modern HW). Assuming you've done all of that, preempt-rt will give you essentially the same guarantees because of the scheduler work linked.

Yes, AGL = automotive grade Linux.

German Software Engineer here. I'd rather chop off my left pinky than working on any software product any German car manufacturer is developing: 1) Their management hierarchies only consist of MBA suits that think short term and treat their engineers like apes in a zoo. This frequently leads to engineers actually behaving like apes in a zoo. 2) German culture is deeply based on thinking in silos. They divide everythi…

"chop off left pinky" - that's an interesting thing to say. Have You by any chance been working for a small Japanese outfit these past few years?

No it's a shout-out directed toward all the emacs users out there

Everyones talking about alot of negatives. But I have a E53 AMG 4matic+ coup. It looks amazing, like constant compliments, i've even had people compliment it and give me their number in a wendy's drive through. But the OS(MBUX 2) is actually really good, at first I was a bit negative on it. But the way they have everything integrated that isn't really possible with apple play is nice. The dash is customizable, I have…

Sir, this is a Wendy’s.

Do you not see a difference from a Mercedes logo on the hood and and McDonald’s ads blaring from the infotainment system?

Obviously they are different. You think they are beyond what I just painstakingly pointed out as one of degree and a degree that you are entitled to feel differently about each case? How do you think your comment advances the discussion, just out of interest? Fwiw I don't tune my radio to commercial FM. I do have badges on the outside of my car and I kinda wish I didn't but not enough (yet) to have done something abo…

The difference between those two things is kind of like the difference between skipping beef on Mondays and refusing to eat food that was cooked in the same kitchen as meat. It doesn’t really make sense to ask without context, right?

Ok... What car brand has the least bad UI these days? I have been putting off getting a new car for about a year.

I have a recent Mazda. It boots to CarPlay pretty quickly. Its native controls are pretty utilitarian when they are needed (e.g. to switch to native SiriusXM when cell signal is spotty). I even prefer the look of its maps although I don't use them. Nothing in the car is a touchscreen. And, get a load of this: they still have actual and intuitive physical buttons for climate controls, defrosters, and driving modes. Oh…

Not only that, mazda has properly working buttons for infotainment: if you press "nav" or "music" it will bring you back to last one you used. So if I use FM radio and Android Auto maps - buttons leads me where I want them to lead me. So many cars had physical buttons, always lead to built-in apps instead of Android Auto and Car Play.

Someone says they are ethically opposed to eating meat. Ask them how far they go with that.

There ya go, fixed the analogy for you. Do you understand now?
