Thread: How much lines per day?

How much lines per day?

From

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?

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.
