10 Repository subscriptions
11 ========================
15 <p><img border="0" src="_files/nd_subscriptionstats.png" title="Statistics of new repository subscriptions for all supported releases. Note: subscription is only done once per machine." /></p>
20 We encourage you to participate in the `popularity
21 contest <http://popcon.debian.org>`_ (popcon), which anonymously
22 collects the list of packages you installed/use on your system.
23 Collecting such statistics is of particular importance for research
24 software projects as a prove of an existing user-base. If upon
25 installation of the system you rejected the invitation to participate
26 you can always change your decision by running::
28 sudo dpkg-reconfigure popularity-contest
32 If you are deploying multiple systems through cloning, to not have
33 all systems considered as one, it would be necessary to re-generate
34 the random MY_HOSTID. Following commands ran as root should do it
35 (as root) without any interactive dialog::
37 sed -i -e 's,PARTICIPATE *= *.no.,PARTICIPATE="yes",g' -e '/^ *MY_HOSTID/d' /etc/popularity-contest.conf
38 DEBIAN_FRONTEND=noninteractive dpkg-reconfigure popularity-contest
40 In addition to popcon pages for your "core" distribution (e.g. `Debian
41 <http://popcon.debian.org/>`__ or `Ubuntu
42 <http://popcon.ubuntu.com/>`__) you can see/get statistics for
43 submissions to `NeuroDebian <http://neuro.debian.net/popcon/>`__ and
44 know that you are already contributing back to the community.
