    That is to say, they hack at it until someone from the business side says, “Yes, that’s what we wanted.” 90% of the development time is spent doing re-work (because no one, including the customer, understood the requirements) and putting out fires (because no one, including the customer, understood the requirements well enough to tell you how to test it, so things are going wrong in production).

    You mean there's an industry out there that does not approach software development that way? Pray, do tell, I shall be blowing the mould off my diseased and tear-soaked CV.

    Obviously, just use a StringVariable and put JSON inside of it. Then you've got all the fun of XML and JSON together! In a bug-riddled enterprise system!

    As someone who works in automotive software, I can attest that the first paragraph is correct, and that I'm not surprised by this at all.

    They could have created a program creating an XML with all permutations of basic variables and each type of collection ...

  • Mischa (unregistered)

    Limiting the possible "generic" variations of collections in a standard does have the benefit that you could test each and assume that every service supports all of them. Otherwise your list of maps of floats to curves may not be supported by some service routing the data.

    As someone who has worked with an automotive standard that got adopted by a non-automotive company (my god WHY!?) I can say that their standards are absolutely this way. At one point we discovered that the serial cable we had running to the box could not be more than a certain length, because the packets had to arrive within a minuscule time period of when they were sent (the only testing had been using a 2ft cable on someone's desk). Our USB connection had to be direct to the computer, using a USB hub/Active Cable/cable longer than 10 feet screwed up addressing and caused the box to register itself as a mouse (and watching data come in and get resolved to mouse movements/clicks made very... interesting things happen to the computer.

    fast-paced or past-faced?

    I'm guessing both.

    FloatFloatFloatMapVariable sounds like we're on a sinking ship.

    that was the XML output of the program generating all the permutations

    what the hell is a String String Curve????

  • Ran (unregistered)

    Why do the 'Map' types seem to have three type arguments? In (e.g.) 'FloatStringIntMapVariable', which of {float, string, int} is the key type, which one is the value type, and what is the extra one for?

    What, no love for ASN.1?

  • Doug (unregistered) in reply to Kashim

    Previous versions of Windows used to detect any serial input during boot as a serial mouse. The solutions were to not have any serial input at boot time, to mess with the registry, or to avoid using versions of Windows older than about Win 8.

    Yes, automotive standards are weird. The best example is the nice "ODB-2" connector that exists in modern (post 1995 I believe) vehicles. You see there are TWO standard protocols used here. One uses one set of pins, and another a couple of different ones. Vehicle makers pick onr or the other. The unlucky scanner vendors need to support BOTH. Thankfully the connector is "standard", but only to the automotive industry.

    Of course if computer people did it (like the IETF guys) they would properly use a nice serial port (most likely an DE-9 connector) and define nice logic levels. Another alternative might be something like MIDI which also was defined by someone who knew what they were doing.

    If you look at vehicles, about the only electrical standard is that they run on is 12 volt batteries (which is about 13.5 in a running vehicle). Good luck with anything after that.

    I even expunged all mention of ASN.1 from my dev profile/cv. Along with a few other tehcnologies I know but have no wish at all to work with. :P

  • (nodebb) in reply to Sole Purpose of Visit

    String String with string, String string string float and string. Or map boolean variable curve factory, with generic template abstraction and string.

  • (nodebb)

    You can see at a first glance that this schema can't be right. It simply can't.

    What did they do to the wonderful smooth parabola it was intended to be?

    (Btw, I didn't expect a customer not understanding or even knowing their own requirements was not so specific to the automotive industry.)

    And what about StringStringStringMapStringStringFloatMapMatrixVariable? According to my experience with this kind of stuff, something like this will be necessary (maybe only temporary) in the near future.

  • (nodebb) in reply to Doug

    Well, I guess that's better than NT 4.0, which had a single BOOT.INI switch to disable serial mouse support. (As if you'd need to support a serial mouse and another serial device...)

    There were 6V vehicles back in the day (eg the VW Beetle) and most trucks run 24V so the 12V "standard" is as standard as anything else! Even then, what is the standard connector for this power source?

    I remember in my parents' 1976 Ford Falcon its cigarette lighter was bigger than other cars so no plugin accessories would fit.

  • Chris (unregistered)

    What about StringIntBoolString? It's only got a little bit of String...

  • (nodebb) in reply to urkerab

    Not so much serial mouse and other serial device, no. It was to stop serial mouse detection from watching the serial port and thinking that bytes X,Y,Z that were received from the other device were in fact from a mouse.

  • Dave (unregistered) in reply to Kashim

    Had a similar problem with another global industry body, they adopted a standard designed by a particular large company whose name rhymes with Doortel. "Look at our perfect solution, you should all adopt it". Turns out this had never been tested outside a LAN, with close to zero latency and zero packet loss. As soon as it was run outside a perfect-conditions LAN, it fell over catastrophically. This is why the first version of the protocol was "version 2", since what was supposed to be version 1 didn't actually work in the real world.

  • (nodebb) in reply to Steve_The_Cynic

    My bad, I thought it disabled detection on all ports, but in fact it was also configurable.
