3.6. HP as an Open Source Software user and contributor

HP doesn't make a lot of noise in the free software world, even if it is an actor and also a user for its own IT infrastructure. For example, all the incoming mail in HP goes through PostFix servers

#dig hp.com -t mx | grep MX
;;      hp.com, type = MX, class = IN
hp.com.                 21m28s IN MX    50 cossmtp.hp.com.
hp.com.                 21m28s IN MX    50 palsmtp.hp.com.
hp.com.                 21m28s IN MX    20 postal.agilent.com.
hp.com.                 21m28s IN MX    10 envelope.hp.com.
hp.com.                 21m28s IN MX    10 letter.hp.com.
hp.com.                 21m28s IN MX    20 stamp.agilent.com.
hp.com.                 21m28s IN MX    30 cossmtpx.hp.com.
hp.com.                 21m28s IN MX    50 atlsmtp.hp.com.

Identically, for its institutional Web server, HP uses Apache as more than 15 millions of other sites.

#wget -S http://www.hp.com/
--15:09:45--  http://www.hp.com:80/
           => `index.html.1'

Agilent (old-HP branch) uses also the free software Perl for CAD as related at http://perl.oreilly.com/news/agilent_0300.html

HP also worked on the improvement of the proxy-cache Squid , as related at http://www.hpl.hp.com/techreports/1999/HPL-1999-142.html

In another domain, HP produces also documents to help convincing to the use of Open Soure Software, as this HP Labs report available on http://lib.hpl.hp.com/techpubs/2001/HPL-2001-233.html

A lot of HP people work on open source projects. They deserve a particular notice because, as in every open source project, their tenacious and constant comportment make these projects alive. Among them:
