Обсуждение: Re: PostgreSQL and success of OSS
Hi Brent ...
I'm CC'ng in the -www group of PostgreSQL, since you are asking
questions that will need to be pulled in from various sources ... and/or
are difficult to answer over all ...
The one that I can try and answer is the Developer Team Size, which is a
# that is very hard to arrive at .. the 'clearly defined developers' are
all listed at:
http://www.postgresql.org/developer/bios
Of which we have >50 ... but, this doesn't include everyone and anyone
that has ever contributed a patch to the source tree ... our -hackers
mailing list, where most, if not all, of our talks about development take
place, there are over 1400 subscribers, so there are *alot* of ppl
lurking, or, if not lurking, providing periodic comments concerning
development ... not all of those are "coders" ...

Also pertinent to such assessments is the Open Source Maturity Model <http://www.seriouslyopen.org/nuke/html/index.php> which has some interesting ways of measuring projects. As you might guess, PostgreSQL is right off the scale on every one of their metrics :) Cheers, D -- David Fetter <david@fetter.org> http://fetter.org/ phone: +1 415 235 3778 AIM: dfetter666 Skype: davidfetter Remember to vote!

I wonder if that number would need to be bumped up in a rather handwavy manner
(amybe +50) on the grounds of companies like enterprisedb, fujitsu,
greenplum, and sun, which I would guess have developers working behind the
scenes on issues thier companies care most about, which then get filtered up
through a few individuals to the community at large. Additionally we also
have more "closely tied" projects like slony and npgsql to draw in more
people. Thoughts?
