So I try not to think too hard on metrics, and just use them to get a
rough view on who is active.

I've been very interested in measuring community involvement, with the
knowledge that any metric is flawed and we should not ever say "this metric
is how we measure the quality of a contributor". It can be helpful, though,
to track some metrics and their change over time.

Here are a few measurements we can make:

Thanks, it was nice to see a more comprehensive list in one spot.

It would be neat to have a tool that presents all of these
automatically, but I think the email ones are pretty tricky (most people
don't have the whole list archive sitting around).

I do not think it covered e-mail at all, but there was git stats
project several years ago (perhaps part of GSoC IIRC).

I think I mentioned "surviving lines" elsewhere, which I do like this
(and almost certainly stole from Junio a long time ago):

Yeah, I recall that one as part of counting how many of 1244 lines
Linus originally wrote still were in our codebase at around v1.6.0
timeframe (the answer was ~220 IIRC) ;-)

And if you do not remember precisely, you can easily re-run `Linus` from
