The biggest problem I have with counting `code size' (yes, we use sloccount at
work), is that given more time and resources than needed to implement the
required functionality, code size usually shrinks due to clean ups. So it costs
_more_ money to decrease the #loc. Software is just like protocols design:

| left to add, but when there is nothing left to take away.

Of course this is less true for the Linux kernel than for proprietary
commercial software, since we don't care about deadlines and take our time to
clean up bad code ;-)

So please don't settle for less than $500000000 :-) ... and I actually prefer
500000000 EUR :-) Which is actually pretty close to $500000 for each of the
10000 monkeys...

when I'm talking to journalists I just say "programmer" or something like that.
