Not so bad actually, assuming each line is 80 characters (like an old punch card) then you'd need 1.35 petabytes of storage for the source, which isn't uncommon these days. Although the build might take a while. -- *Greg K*
Re: What's a million lines of code worth?
I have read somewhere in the media before that TDD is not even being used for the F35's development. I thought writing something so complex without it would be crazy, myself. Not that TDD is a silver-bullet, but in my experience it does make a substantual difference to quality. Hopefully they have some sort of automated testing process in place. They may have other tricks as well. While they're probably using the Ada programming language (which is known for its robustness), simple things like making variables immutable by default can help reduce side effects - especially in concurrent systems (which I'd imagine the F35 probably is) since the precise order of execution is not known.

Re: What's a million lines of code worth?
19,000,000 million lines of code for 21,000,000,000 dollars for 58 planes averages out at about $19 per line. Now there's some incentive to code fast. But I enjoy deleting lines of code as well, I wonder if they pay for that -- *Greg K* On 23 April 2014 12:51, Paul Evrat wrote: > Hi All, > > > > Collins Class Submarine – 6 million lines of code. > > > > Joint Strike Fighter – 19 million lines of code. > > > > Seems plausible OR Over-bloated software development mismanagement ?? > > > > Not saying one way or the other, just interested in your professional > gut-feels ? > > > > Article - > > http://www.abc.net.au/am/content/2014/s3990236.htm > > > > Paul E .. > > > > > > > > >

Wonder what the acceptance tests on a missile launch system would look like.

Considering that there are a number of systems it doesn't seem that many. Do they include the unit tests? There are unit tests aren't there in the missile launch systems!

Hi All, Collins Class Submarine - 6 million lines of code. Joint Strike Fighter - 19 million lines of code. Seems plausible OR Over-bloated software development mismanagement ?? Not saying one way or the other, just interested in your professional gut-feels ? Article - http://www.abc.net.au/am/content/2014/s3990236.htm Paul E ..
