  • Hm it’s probably “bundle with the hardware, make sure the hardware really works and there’s a price incentive vs Windows”.

    As long as you have to actively migrate (including backing up, losing access to several commercial apps) and could end up in the situation that your hardware isn’t 100% working or you’re workflow isn’t really supported?





  • Some thoughts from my side (coming from another domain - more embedded):

    • Whether you use a message string or a named bool does not change anything. It’s still logging.
    • It’s of course nice to just trace everything and filter / search afterwards, but in embedded for example your machine may just crash if you try that. For that log levels are the traditional way to filter before a log is written.
    • I don’t get how timestamping / ordering is necessarily worse for logging. Maybe it’s just the framework that is used?
    • You sure can have hierarchical information in log frameworks

    In my opinion log levels sure make sense, but it may vary wildly depending on what you’re doing. We run our software in different environments:

    • Development machines / VMs
    • Development boards
    • Production ECUs

    And it’s run by different sets of people:

    • Devs
    • Integrators
    • Customers

    Depending on the combination of where / who you get different requirements.

    I get that Logging is hard and often you get messages with a wrong log level or you’re missing a message at a crucial point etc. But tracing is not better in every way - they should complement each other.



  • Doubtful. Android automotive OS runs on a single ECU in the car while a lot more are in there running QNX, Linux or some embedded OSes (sometimes there are more than 100 such ECUs in the car). So there’s no guarantee that the “problematic” services are even running on this ECU (I bet it’s more distributed). Furthermore updating / changing the software of a single ECU is done using special hardware or through some kind of gateway ECU. They will perform validation on the to-be-flashed software to ensure it’s from the vendor itself.

    And even if you’d get it flashed I can guarantee you that nothing will work.
