or was it NASA Mariner 1 ? http://en.wikipedia.org/wiki/Mariner_1#Overbar_transcription...

Anyway, as always wikipedia has an interesting list of software bugs : http://en.wikipedia.org/wiki/List_of_software_bugs

I found interesting the computer crash of F22-Raptors after crossing the International Date Line.




They don't have a Mercedes Smart bug where they mixed left and right causing the car to throw itself on its side when going through a turn.

(edit) ... and I'm downvoted. Lovely. Totally makes sense.


You probably got downvoted because you just listed this bug without offering any type of proof that this bug actually happened.


When did HN turned into Wikipedia?


I think you mean a Mercedes-Benz A class, in the moose test (http://en.wikipedia.org/wiki/Moose_test)

I have never heard that was software related, but it also is a decent bet software was involved, e.g. for stiffening the suspension. What top of the line car did not have software, in 1997?


To have software involved with the suspension requires an active suspension, which was rare in 1997. Mercedes added an electronic stability system only after the Moose test failed, so I don't think it was a software problem in the first place (rather software fixed the problem).


That's the one, bingo. It was a new line of smaller MBs, so I misremembered it being Smart. The issue though was most certainly with the software overcompensating the roll in the wrong direction. I would've not remembered it otherwise :)


The A class didn't have active suspension. I believe it was a mechanical issue and solved with a stiffer front anti-roll bar and other suspension geometry tweak. Though there is a possibility the ESP was tweaked to apply the brake under such circumstances I think that could do more harm than good. I could be wrong, it was 1997.. IIRC the non-ESP MB Sprinter also had stability issues.


@sebbi - you are shadow-banned.


The A was as far from top of the line as MB goes. It was a cheap, entry-level model.


Don't they test these programs in virtual cases with simulations of realistic data, speeds, angles, altitudes, etc...?


I don't know if it is just a mis-telling of the F-22 bug (I suspect it may be), but I have heard of a bug in the autopilot software of some fighter plane that would cause the plane to flip upsidedown when it was south of the equator on autopilot. Presumably this bug was discovered during simulations, and was never actually accidentally triggered in the wild.


In 1962 there wasn't exactly enough computational power anywhere to do a reasonable simulation of a flight.
