How much lines per day?

Hi,

While attending a Linux conference, a guy said that 10,923 lines of
code are added and 5,547 lines of code are deleted per day in average
in Linux development. This is an interesting number and I just wonder
anybody ever tries to calculate these numbers with PostgreSQL.

Does anyone know such number?

Not really what your are looking for, but also interesting:

With some script binding the PG SCM you could easily find that.
It's all about SUMming "--" and "++" from commit diffs.

Since 8.5alpha1:
$ git diff --shortstat origin/REL8_5_ALPHA1_BRANCH origin/master
618 files changed, 43682 insertions(+), 24382 deletions(-)

That was on Aug 19th, which was about 63 days ago. However, to be
meaningful, we should subtract away the changes to the .po files, which
are generated.

So, 43682 + 24382 - 9889 (de.po) - 3831 (fr.po) = 54344

54355/63.0 = 862 lines/day.

Not bad. That's essentially one commitfest period, so it would be
interesting to compare with others, as well.
