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.
Different tech has different needs. I can see it being really great with server side distributed systems. I don’t really see it having any benefit for running stuff in resource constrained single purpose environments
To be honest I think we should be adopting the full ecosystem we've been busy building around containerization. Imagine calling up breakdown assistance because your car won't start, mechanic comes out, cracks the hood and is like "ah there's your problem right there, ignition service has only 1/2 pods healthy because the node went into NotReady due to DiskPressure. I can clear up some log files so it goes underneath…
Looks like your cars Kubernetes certificates have expired after a year, we'll need to SSH in and run kubeadm to refresh them. Wait, the 5G pod isn't starting ...
You joke, but I decided I wanted to try out Kubernetes, so I set it up at home and moved some of my local services into it, one of them being my custom lighting automation software. Eventually my lights just stopped working, and after a lot of rummaging it turned out to be expired certificates. I promptly put the software back where it was before, removed Kubernetes, and decided there were better things for me to play around with.
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.
That would obviously depend on the failure mode. But there certainly are failure modes which could be quite damaging, and an ECU may have limited ability to determine what failure mode is occurring, and even if it has sensors that can indicate certain failure modes, it is not always clear if those can be trusted, as they there be additional failure modes that make sensors give misleading results.
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…
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!
Unless I’m missing something, it seems that this information largely invalidates the thesis of your previous post. A critical component (fuel injector) failed, the software in the car prevented it from running and causing catastrophic damage. Roadside assistance came, immediately determined it can’t be fixed on the side of the road and towed the car. Seems like a best-case scenario given the circumstances other than possibly the red herring related to the stability control.
assuming this is a cr2025 then most likely 20mm diameter and 2.5mm thick => 2025
Yeah almost certainly talking about a CR2025.
Use of a 2025 cell would be rather irritating to me, because in my experience CR2016 or CR2032 are both more common, and it seems like it should not be hard to fit a 2032 into most keyfob designs.
> The printers of today are awful landfill fodder compared to the Okidata's of the 90's. Pure simplicity and speed vs FULL COMPUTERS, with scanning, faxing, and every other imaginable feature crammed in with zero hope of doing anything other than replacing the toner. The first Laserwriter in 1985 had more processing power than the Macintosh it was sold to accompany. Printers have been full computers for a long time n…
People used to buy HP Laserjet 4 printers at auction because they were peak stability. From the look of things the 4 introduced the direct predecessor to the wire protocol printers use today (PCL 5e vs PCL 6 variants) https://en.m.wikipedia.org/wiki/Printer_Command_Language
Our helpdesk offered us to take our LJ2100 and get us something newer.
Indeed. When I took my car in last winter because the light had come on for no apparent reason, as the car was running fine, they charged me $140 to take it out on the road to try to find the reason. No reason was found. Two weeks later, the light came on again (towards the end of 2022). The car was and is running fine. The light will remain on until July when I take it in for a scheduled oil change.
Or you could buy a $20 code reader and see what's causing the light yourself.
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.
Most infotainment is already shit code. If same people use more tools the result will just be worse, if they can't even handle a monolith
