DebConf 13 report (by Andreas Tille)
General impression
I'm beginning my DebConf report in an
unofficial
"Scenic Hacklab" right at the edge of the lake in Yverdon. This
is the right place to memorise the last days. When I started from
this place cycling to Le Camp 12 days ago I was full of great
expectations and what should I say - the reality has even beaten
these.
Once it comes about comparing DebConfs even if it is an unfair
comparison due all the differences my secret long term favourite was
Helsinki very closely followed by Argentina and also very closely
followed by all the other great DebConfs I joined (and I joined all in
Europe). Would Le Camp be able to beat it? The short answer is: Yes,
it is now my favourite DebConf while I think I do not suffer from the
last-Debconf-was-the-best-DebConf-syndrome (and I realised there are
others
thinking the same).
As you might probably know I'm a bit addicted to swimming. While
Helsinki had admittedly the better conditions I was at least able to
fix the distance issue using my bicycle. (Hey, those Le Camp
photographers did a great job in hiding the fact that you can not
actually touch the lake right from the meadow of Le Camp.) Being able
to have my bicycle at DebConf scored some extra points. However, the
really great view of the lake, the inspiring "Scenic Hacklab" which
was my favourite place has bumped DebConf13 at first place in my
personal ranking.
So it comes quite natural to say: "Kudos to the great organisation
team!" They did a Swiss-like precise work and perfectly succeeded in
hiding any problems (I assume there were some as always) from the
attendees so everything went smooth, nice and shiny for the attendees.
The local team was even precise in setting up great weather conditions
for DebConf.
While saying thanks to the local team I would like to also explicitly
thank Luca Capello who has quite some share that this DebConf was
possible at all (while I have to decrease my DebConf score one point
because he was not really there - Luca to bad that you were not able to
come full time!) Also thanks to Gunnar and Gannef who helped remotely
(another score down because I were missing them this year as well).
Even if it was my favourite DebConf I was not able to work down my
todo list fully (which was not only uploading one package per day
which I at least statistically fullfilled). But that's probably a
general feature of todo lists anyway. One item was definitely done:
Doing my daily swimming BoF. I actually was able to do the other
parts of the triathlon which was skipped by Christian and have done in
summary about 150km cycling with 3500m elevation and estimated 7-8km
swimming (0m elevation ;-)). Considering the great view at
sunrise
over the lake I was not hating my
"Senile bed
escape" disease too much (I was every day waking up at sunset) -
it was simply a great experience. I will never forget seeing water
drips glimmering like gold inside the morning sun while seeing the
Alps panorama in the distant. I hope I was able to help all
interested swimmers with the
DebConf Beach Map
which was just a by-product of my activities in DebCamp.
Speaking about OSM: I was astonished that the area was way less
covered than I expected. Thanks to several DebConf attendees the
situation became better and the map does not only show random trees in
the wild but also the tracks leading to these. (Remark: It was no
DebConf attendee who is responsible for plastering the map with single
trees.) While I had my mapping focus basically close to the edge of
the lake I was also able to even map
my very
own street. :-)
I clearly remember one specific mapping tour when I was invited by the
DPL: He convinced me to join him on a bicycle tour and since I was
afraid to get fired I joined him instead to keep on hacking. Also
Sorina was brave enough to join us on the tour and she did quite well.
(Sorina, do you remember the agreement about your work on the installer?
;-)) Lucas described the tour as: going uphill on only asphalted roads.
Sorina and me were witnessing the mighty DPL powers when we left the
wood around Le Camp to reach the described road: The asphalt was just
put onto the road - no doubt that it was done on the immediate demand of
mighty DPL. :-)
DebCamp time was flying like nose dive and a lot of known (and unknown)
faces arrived at Le Camp. What I really liked a lot this year was that
several really young children has pulled down the average age of DebConf
attendees. I clearly remember all the discussion one year ago what to
do about children. As always the issue was solved in a typical Debian
way: Just do it and bring your children - they had obviously a great
time as well. I think the youngest child was 2 months and the oldest
"child" above 20. ;-) Actually Baptiste Perrier did great in making the
C&W party a success and had obviously a nice time. (I wished my son
would have been able to come as well but he needs to write his
bachelor s thesis in physics. :-()
It was nice to see the kids using all playing facilities and
communicating with geeks. Also I would like to point out that even the
very young attendees had their share at the success of DebConf: Just
think of the three "bell ringing assistants" who helped me ringing the
bells for lunch and dinner. I've got this cool job from Didier in the
beginning of DebCamp. I must say having some real bells ringing is by
far nicer than just the "lunch / dinner starts in 10 minutes" from IRC
bot. The only thing I did not understand was that people did not
considered ringing the bells at 8:00 for breakfast as a good idea.
Regarding the food in general I would also like to send kudos to the
kitchen: It was tasty, freshly prepared, regional food with a good
change rate. I really liked this. Extra points for having the chance
to sit outside when eating.
Talks
But lets have a look into the conference programme. I'd really
recommend watching the videos of the talks
Bits
from the DPL (
video)
and
Debian
Cosmology (
video).
I considered both talks as entertaining and interesting. I also
really hope that the effort Enrico Zini started in
Debian
Contributors (
video)
will be successful.
I had some talks and BoFs myself starting with
Why
running a Blend (
video)
and I admit that (as usual) the number of attendees was quite low even
if I think there is some proof (see below) that it is interesting for
way more people who should consider working more "blendish" in their
team. Do you know how to recruit one developer per year and relax the
man power problem in your team? Feel free to watch the
video.
We have confirmation that ten DDs of our team have considered to join
Debian only because Debian Med exists. Admittedly biology and
medicine are really leaf topics inside the Debian universe. So if
even this topic that has a very tiny share of the Debian users is able
to attract this level of attention - how many more people could we win
for multimedia, games, GIS and others?
So if you feel you are quite overworked with your packaging and you
have no time this is most probably wrong. The amount of time is
basically a matter of priorities you set for your tasks. Try to put
some higher priority onto using the just existing Blends tools I
explained in my talk to attract more users and developers to your team
and by doing so spread the workload over more people. It works, the
prove was given in
my
main talk. So before you start working on a specific
package you should wonder who else could have an even stronger
interest to get this work done and provide him with some additional
motivation and help to get the common goal done.
The interesting thing is that my BoF about
How
to attract new developers for your team (
video)
- which was a simple report about some by-product of the Blends work -
made it into the main talk room and got way more attention. For me
this is the proof that the Blends concept itself is probably badly
perceived as something like "a few outsiders are doing damn specific
stuff which is not really interesting for anybody else" instead of
what is really is: Smoothing the way from specific upstream
applications to the end user via Debian.
Once you see the
video
of this BoF you can observe how my friend Asheesh Laroia became
more and more excited about the Blends concept and admitted what I
said above: We should have more Blends for different fields. Funnily
enough Asheesh asked me in his excitement to talk more about Blends.
This would have been a really good suggestion ten years ago. At
DebConf 3 in Oslo I had
my very
first talk about Blends (at this time under the name "Debian
Internal Projects"). I continuously kept on talking about this
(
MiniDebConf
Peking 2005,
DebConf
5, Helsinki (
video),
DebConf
7, Edinburgh (
video),
DebConf
8, Mar del Plata (
video),
DebConf
9, C ceres (

MiniDebConf
Berlin 2010 (

in German),
MiniDebConf
Paris 2010 (not video recorded),
DebConf
11, Banja Luka (
video)
... and these are only (Mini)DebConfs my
talks page is full
of this topic)
and every new year I try different ways to communicate the idea to my
fellow Debianistas. I'm wondering how I could invent a title +
abstract avoiding the term Blends, put "Git", "release" and "systemd
versus upstart" in and being able to inform about Blends reasonably by
not becoming to off topic with the abstract.
I also registered the
Debian
Science round table. I admit we were lacking some input from
remote via IRC which used to be quite helpful in the past. The
attendees agreed upon the handling of citations in debian/upstream
files which was invented by Debian Med team to create even stronger
bounds to our upstream developers by giving their work extra reward
and providing users with even better documentation (see my summary in
Wiki).
As usual I suggested to create some Debian Science offsprings like
"Debian Astronomy", "Debian Electronics", "Debian Mathematics",
"Debian Physics" etc. who could perfectly leave the Debian Science
umbrella to get a more fine grained structure and a more focused team
to enhance the contact to our users. Unfortunately there is nobody
who volunteers to take over the lead for such Blends. I have given a
short summary about this BoF on the
Debian
Science mailing list.
In the
Debian
Med meeting I have given some status report. No other long term
team members were attending DebConf and so I gave some kind of
introduction for newcomers and interested people. I touched also the
DebiChem topic which maintains some packages that are used by
biologists frequently and so we have a good connection to this team.
Finally I had registered three BoFs in Blends I'm actually not (or not
yet) active part of. My motivation was to turn the ideas I have
explained in
my
main talk into specific application inside these teams and helping
them to implement the Blends framework.
In the first BoF about Debian GIS I have shown the usual team metrics
graphs to demonstrate, that the one packaging team Pkg-OSM is in danger
to become MIA. There are only three persons doing actual uploads. Two
of them were at DebConf but did not joined the BoF because they do not
consider their contribution to Pkg-OSM as a major part of their general
Debian work. I will contact the main contributor David Paleino about
his opinion to move the packages step by step into maintenance of Debian
GIS packaging team to try to overcome the split of two teams that are
sharing a good amount of interest. At least if I might become an
Uploader for one of the packages currently maintained by Pkg-OSM I will
move this to pkg-grass-devel (which is the name of the packaging team of
Debian GIS for historical reasons). The attendees of the BoF have
considered this plan as sensible.
Moreover I talked about my experiences with
OSGeo Live - an Ubuntu
derivative that tries to provide a full tool chain to work on GIS and
OSM problems ... basically the same goal as Debian GIS has just
provided by the OSGeo project. I'm lurking on OSGeo mailing list when
I asked explicitly I've got the answer that they are working together
with Debian GIS and are using common repository (which is IMHO the
optimal way of cooperation). However, it seems that several
protagonists of OSGeo Live are underestimating the resources provided
by Debian. For instance there was a question about Java packaging
issues but people were not aware about the existence of the
debian-java mailing list. I was able to give an example how the
Debian Med team managed to strengthen its ties to
BioLinux that
is also an Ubuntu derivative for biologists. At our first
Debian
Med sprint in 2011 we invited developers from BioLinux and reached
a state where they are using the very same VCS on Alioth where we are
maintaining our packages. At DebConf I was able to upload two
packages where BioLinux developers did certain changes for enhancing
the user experience. My "work" was just bumping the version number in
changelog and so we did profit from the work of the BioLinux
developers as well as they are profiting from our work. I plan to
dive a bit more into Debian GIS and try to strengthen the connection
to OSGeo Live a bit.
The next BoF was the Debian Multimedia meeting. It was nice that the
current leader of
Ubuntu Studio
Kaj Ailomaa joined the meeting. When I was explaining my ideas about
cooperation with derivatives I repeated my detailed explanation about
the relation with BioLinux. It seems every topic you could cover
inside Debian has its related derivative. So to me it seems to be
quite natural to work together with the developers of the derivative
to join forces. I actually consider a Blend a derivative done the
right way = inside Debian. The final work for the derivers that might
be left for them is doing some shiny customising of backgrounds or
something like this - but all the hard work could and should be done
in common with the relevant Debian team. My dream is to raise such
relevant teams inside Debian ... the Blends.
Finally the last BoF of this series was the Debian Games meeting. As
always I presented the team metrics graphs and the Debian Games team
members who attended the BoF were quite interested. So it seems to be
some unknown fact that
team metrics are done
for several teams in side Debian and so I repeat the link to it for
those who are not yet aware of it. As a result of the BoF Debian
Games team members agreed to put some more effort into maintaining
their Blends tasks. Moreover Miriam Ruiz wants to put some effort
into reviving Debian Jr. Regarding Debian Jr. there was an
interesting
talk
about DouDouLinux - in case you might want to watch the video I'd
recommend skipping the first 30min and rather watch the nice live
demo. There was also an ad hoc BoF about Debian Jr scheduled to bring
together all people interested into this cute project and Per Anderson
volunteered to take over the lead. I have given
a
summary about this specific BoF at the Debian Jr list.
For some other talks that I'd regard as remarkable for some reasons:
I'd regard the talk
"Debian-LAN"
by Andreas Mundt as some hidden pearl because it did not got a lot
of attention but after having seen the video I was quite impressed -
specifically because it is also relevant for the Blends topic.
Memories
I also liked
"Paths
into Debian" by Moray Allan (and I was only able to enjoy the
latter talks thanks to the great work of the video team!) because it
also scratched the same topic I was concerned about in
my
mentoring talk. Related to this was in my opinion also
"Women
in Debian 2013" were we tried to find out reasons for the lack of
woman compared to other projects and how to overcome this issue.
Besides the talks I will probably never forget
two specific moments that make DebConf so special. One of these
moments is recorded on an image that clearly needs no words - just
see Geert hovering over the grass.
Another strong moment in my personal record was in the DebConf Newbies
BoF
"First
time at DebConf" that unfortunately was not recorded but at least
for this statement it would have been very great if we would have some
reference better than personal memory. Aarsh Shah a GSoC student from
India suddenly raised up and said: "Four months ago I was not even
aware that Free Software exists. Now I'm here with so many people who
are totally equal. If I will tell my mother at home that I was
standing in the same queue where the Debian Project Leader was queuing
up for food she will never believe me." He was totally excited about
things we are regarding as normal. IMHO we should memorise moments
like this that might be part of the key to success in cultures, where
Debian is widely unknown and very rarely in use.
Amongst these not scheduled great moments the scheduled day trip was also
a great thing. I had a really hard time to decide what tour I might
join but ended up in the "long distance walking (or should I say
running) group". Inspired by the "running Bubulle" who was flashing
between the walking groups we went uphill with 5.4km/h which was a nice
exercise. Our destination the large cliff was an exciting landscape and
I guess we all enjoyed the dinner organised by the "Trout cabal". ;-)
So I had a hard time to leave Le Camp and tried hard to
make sure my memories will remain as long as possible. Keeping some
signs attached to my bicycle, conserving the "Scenic Hacklab" sign
for my private "scenic hacklab @ home" was one part. I also have cut
some branches of the Buxus sempervirens in Le Camp and have put them
in my garden at home (where I create some hedgerow from places where
I spent some great time). These will probably build a great part of
the hedgerow ...
Thanks for reading this longish report.
Looking forward to see you all in Germany 2015 (or earlier)
Andreas.
What happened in the reproducible
builds effort this week:
Media coverage
Nathan Willis covered our DebConf15 status
update in Linux Weekly News. Access to
non-LWN subscribers will be given on Thursday 24th.
Linux Journal published a more general
piece
last Tuesday.
Unexpected praise for reproducible builds appeared this week in the form of
several iOS applications identified as including spyware. The malware was
undetected by Apple screening. This actually happened because
application developers had simply downloaded a trojaned version of XCode
through an unofficial
source. While reproducible builds can't really help users of non-free software, this is exactly the kind of attacks that we are trying to prevent in our systems.
Toolchain fixes

On the next two days at the booth we chatted and discussed with visitors and other exhibitors a wide variety of questions, including 'When will be (the next Debian version) released?' and 'Are there installation disks available?'. The answers was as always 'When we are ready and we will have reached the quality-level we defined', 'No we don't have installation medias, as they are always outdated. Do you have an USB-dongle with you?'.
Merchandising was requested by visitors as always, but we just had some leftovers of fosdem, brought by Axel.
Many thanks to Florian Baumann, Jan Dittberner, Andreas Tille, Christian Hoffmann, Axel Beckert, Markus Rekkenbeil, Daniel Schier, Jonas Genannt, Jan H rsch and kurio for taking care and running the booth, which worked out this year extreme smoothly from my point of view. Likewise as the last years a special thanks to
