Adding a `sleep $DELAY` to a startup script isn't something to brag about :-P. scnr
They removed it.
We achieved a 6-fold increase in Podman startup speed

Re: We achieved a 6-fold increase in Podman startup speed
#22I'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…
You said it so well, cars have become too bloated with software that barely any local mechanic would want to touch it. Happened to me and this is the major reason why I am slowly shifting to older cars, they are way easier and cheaper to repair.
Same here - I have owned an old petrol Vauxhall for years as my runaround car and it's so much easier to deal with. The big issue I have with newer cars is that the computers mask any developing issues until they get to a point when they just give up. A less sophicsticated car starts to just feel different a long time before it outright fails.

I'd go further than cars and say, "in most things". Smart-anything, washing machines, printers, sewing machines, thermostats, appliances in general...
My mother in-law has two sewing machines. One of them is one of the first electronic sewing machines (from the 70s) and one is much older. Guess which one still works like a charm?
I'm not arguing against electronics, here-- many of these things are no doubt improved by electronics to such a degree that the tradeoff is worth it, but it's good to at least acknowledge that there is a tradeoff. It's also good to try to minimize the impact of electronic failure. Smart things would ideally just revert back to being functional dumb things (rather than bricks) if their electronics fail.

#24> If the backup camera or other sensors were to run as containers, we needed to improve the starting speed significantly. I think I see the problem already. Why does anyone think its a good idea to put everything in an embedded system into a container? Particularly as everything comes from a single vendor and so the usual argument about "but libraries are too hard!" doesn't apply.
I agree. Microservices are a great concept for a lot of problems. But now I constantly see way too small services. Every tiny piece of software gets its own service and its own software lifecycle (including versioning and deployment). And what happens now is, that you need a huge effort to integrate all those components. End to end system tests get much more important, but are still harder to do than simple unit/inte…
You are blaming cultural issues on technology. You have the same integration pains with libraries too. In general if your teams are not aligned, it doesn't really matter if they are developing microservices, libraries, or one spaghetti ball mess, its going to be problem anyways
Re: We achieved a 6-fold increase in Podman startup speed
#25Do we know which cars specifically run their applications in containers?
Re: We achieved a 6-fold increase in Podman startup speed
#26Why does a car even need to run containers? It's a known hardware, so why containers? Feels like lazy engineering.
Re: We achieved a 6-fold increase in Podman startup speed
#27Why would you run podman inside a vehicle's computer. Cool nonetheless.
Perhaps you want to somehow isolate different parts of the car to protect against somehting like the CAN bus attack?

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 config and only be updated from the "config manager" (inforatinment box). If infotainment box dies, everything else still works.
Cars already are basically "microservices on a message bus". Let's just use what works with that - minimal coupling and maximum independence of "services"
> Had I been in a less complex car, a local garage could most likely have fixed the problem and sent us on our way. The sophistication and gadgets in modern cars are great until something goes wrong then they fail hard. Small local garages that used to be a life saver are next to useless now as they don't have the tools and knowledge to fix a mobile data centre.
Out of curiosity, what was the issue ?

If something like that needs to be smart the smart part should basically be extra interface. Old printers did it right - separate extra box for all the connectivity working as print server. That breaks ? just connect it directly.
But hey, feeding everything from single microcontroller is $2 cheaper...

Especially a thing that should be just "a device that puts video stream on whatever bus it uses". infotainment already uses html/js based UIs, just embed video player in there...
