I'll reiterate my original point as nobody but Phantasee seems to have noticed it. I'm not particularly concerned by the copyright infringement, or the magnitude of the error they
first discovered.
The critical thing is that they were using untested, low level, hacked together software.
How do we know that its low level software? Changing the specific chip architecture caused it to stop working entirely. Why is it important that it is "low level" software? Well, that program isn't going to be running on windows7. Back in the dark ages of computer programming if you fuck up your program there was no sandboxing or whatever, no actual protection from yourself. You could genuinely trash the entire operating system depending on what you did. Allocated some memory in the wrong place? Whoops, you overwrote some of the OS, time to take out the hardware and manually reprogram it. The FIRST bug they discovered was that it was fucking up floating point operations. That is a pretty fundamental thing. If thats going wrong then theres absolutely no reason to assume anything in the code is doing what you want it to. They then say that they discovered more errors later, that 13m wasn't the end of it:
"the spatial toolkit hack" in Netezza emails when it began producing further errors in November
The fact they had adapted an existing program is even worse than blindly playing with the source code, this could cause untold problems, and doing it this way
there is no possible way to test whether this will break at a later time.
You may not care if all bombs that are dropped have an additional 10m of inaccuracy. This was
certainly happening.
You may not care if occasionally you bomb the house of the first 'Abdul' in the phonebook instead of the 'Abdullah Bloggs' you actually entered because theres a subtle pointer arithmetic error that cuts off a string in certain situations. This is
easily possible.
You
will care if, due to the differences in chip architecture, what was a trivial memory operation on the previous chip, now you go and overwrite the software that is flying the drone, and every single drone that was flying at that time you entered the query crashes to earth. This kind of flaw could be in the software, and there is no way to know if or when it will happen.
Apparently nobody can see you without a signature.
