There is now an Ubuntu PPA for
Obnam,
with packages uploaded by the awesome
Chris Cormack of Koha fame.
His mail to the (very low volume) Obnam mailing list has details:
http://lists.liw.fi/obnam@braawi.org/msg00013.html.
If you experience any problems with the packages, don't hesitate
to mail me, or the Obnam mailing list, or tell us on the
#obnam IRC channel on irc.oftc.net.
mr (multi-repository) is a useful script
by Joey Hess for managing multiple version control
check-outs. It's particularly useful for team Debian package maintenance,
where you can have a common mrconfig file allowing team members to have easy
access to all packages. Here's the mrconfig file for the Games
team
(which bizarrely only lists git repositories despite being maintained in svn ).
It could also be useful for maintaining a collection of puppet modules from separate places.
I frequently find myself wanting to sanity check my local copies of
repositories. Have I forgotten to push commits upstream? Are my local branches
not up-to-date? In a package management context, have I remembered to tag each
package release? Are all the upstream releases tagged?
To aid this process, I've hacked together a script I've called mr-lint. This
reads your mrconfig file and performs the above tests on every repository it
finds. It attempts to determine whether the check-out is a debian package or
not, and performs additional tests where appropriate.
Sample output:
$ mr-lint wd/debian/bup
wd/debian/bup: local branches not present in origin: rescue-diverge
wd/debian/bup: local branch debian does not match origin branch debian
wd/debian/bup: local branch master does not match origin branch master
wd/debian/bup: 5 missing upstream tags: 0.21, 0.17b, 0.20, 0.24b, 0.14a
wd/debian/bup: 3 missing debian tags: debian/0.17b-1, debian/0.20-2,
debian/0.21-1
mr-lint because I hope that if people think the idea is sound
or the script useful, I might be able to adapt it into a patch against mr
itself. Here's the script. If there is any interest, I'll put
it somewhere more permanent.

So there are two things I stumbled upon with caff:
A new maintenance release version 0.9.6 of
Rcpp
went onto CRAN and into
Debian earlier today.
This release contains a fix which helps the RppEigen package
(mentioned previously on this blog), as well as an
addition which permits user-defined finalizers for external pointer objects (following a suggestion on the mailing list). Two new examples
where added: a Gibbs sampler illustration (blogged about as well)
and a Rcpp-based Fibonacci implementation following a question on StackOverflow. And while that last
example is clearly degenerate, the 700+ fold net speedup (as shown in
my answer) is still pretty neat.
The complete NEWS entry is below; more details are in the ChangeLog file in the package and on
the Rcpp Changelog page.
0.9.6 2011-07-26
o Added helper traits to facilitate implementation of the RcppEigen
package: The is_eigen_base traits identifies if a class derives from
EigenBase using SFINAE; and new dispatch layer was added to wrap() to
help RcppEigen
o XPtr now accepts a second template parameter, which is a function
taking a pointer to the target class. This allows the developper to
supply his/her own finalizer. The template parameter has a default
value which retains the original behaviour (calling delete on the
pointer)
o New example RcppGibbs, extending Sanjog Misra's Rcpp illustration of
Darren Wilkinson's comparison of MCMC Gibbs Sampler implementations;
also added short timing on Normal and Gaussian RNG draws between Rcpp
and GSL as R's rgamma() is seen to significantly slower
o New example on recursively computing a Fibonacci number using Rcpp and
comparing this to R and byte-compiled R for a significant speed gain
Thanks to
CRANberries, you can also look at a
diff to the previous release 0.9.5.
As always, even fuller details are on the
Rcpp Changelog page and the
Rcpp page which also
leads to the downloads, the
browseable
doxygen docs and zip files of doxygen output for the standard formats.
A local directory has
source and documentation too.
Questions, comments etc should go to the
rcpp-devel mailing list
off the R-Forge page
jupp 3.1.17 uploaded
today, mostly thanks to user input suggesting I improve things,
especially the syntax highlighting. (Maybe more to come.) I like
users who don t complain but give helpful comments and send in
patches even.
Since the Debian FTP masters complain that the NEW queue is
empty for the first time in ages, I also uploaded jupp to Debian
proper (got requests, several, from actual users independent
of each other). I originally thought I were the only user, it s
not worth it, maybe too close to joe (which segfaults a lot more
and has some ugly things, so I cherry-picked the better features
of it instead of rebasing jupp), but it s had a package in mports
(MidnightBSD ports) for ages, users submitted one to FreeBSD last
year and keep it updated, there s even a WIP package in pkgsrc ,
and who knows where else or how many people are using my OpenSuSE
Buildservice package or have had installed the previous DEB package
I uploaded to my play repo. So now I feel it worth to upload.
I even invested some major packaging rework, such as
splitting the build-arch and build-indep parts from each other,
and importing the upstream source into the packaging VCS, as I
have learned in the packaging with git talk here at DebConf.
(No guys, I will stick to CVS as git doesn t give me anything.)
Been hot and dry today (although the sky is now back full of
dark clouds), so I had a headache most of the morning until way
past noon. Better now though, and I found a place where I could
get Cevapi, which are really some sort of quick imbiss / fast
food here (no uve pirina though, and she didn t have any
Ajvar nor did she speak any language other than the local, but
that wasn t a problem, only a bit dry because I didn t give in
and took the offered Ketchup). Bought a 1 bottle of Kru kovac
(from Hrvatska, though) and some small plastic glasses, then.
I wonder how many people would, now, be willing to give Bosna
i Hercegovina a try as holiday region (which might have been the
intent of having a Balkan DebConf). I m sure I do.
To all attendees: the hotel will give you some kind of stamped
hardpaper card which states where you stayed on the trip, and for
how long give that to the border guards when exiting Bosnia.
Due to high demand I have prepared official Redis packages for Debian "squeeze":
Add the following line to /etc/apt/sources.list:
deb http://backports.debian.org/debian-backports squeeze-backports main
Update your local package lists:
sudo apt-get update
Install redis-server with:
sudo apt-get -t squeeze-backports install redis-server
Good pile of fixes made it worth to release current klibc git master. Patches came from Gentoo, Google and Openembedded. For details see klibc 1.5.24 release announcement.
I thought it would be a good idea to get some fresh blood into Debian, so my wife and I decided to "create" Melissa. Melissa was born on Monday 25th at 00:47h and was 54cm large and weighed 4200 gram. Of course she already has her first Debian shirt ;).
Continuing the shameless self-praise from our ftp-team talk, I'm now
pleased to present you on behalf of the entire FTP-Team the following:
As you can clearly see, you can see nothing. Yes, nothing! As of
18:55:52 UTC+2 the NEW queue, which at some times was well over
500, sometimes even 600 packages is now empty. Completely empty.
To the best of my (and Ganneff's knowledge) the last time the NEW queue
was empty was at least five years ago.
Interesting enough, that triggered an yet undiscovered bug in dak, which
refused to scan an empty directory...
Recently, I was working with Daf and Rob on a little offline wiki
project -- more on that soon -- and we realized that we needed to
parse some dates in ISO 8601 format. One of us wondered out loud
if there was a Python module that could help us. I offered to take a
look.
Turns out, less than two months before, someone had uploaded just such
a module into Debian. The maintainer? Me.
# Add a system group for Skype addgroup --system skype # Override permissions of skype (assuming Debian package!) dpkg-statoverride --update --add root skype 2755 which skype
iptables -I OUTPUT -p tcp -m owner --gid-owner skype \
-m multiport ! --dports 80,443 -j REJECT
iptables -I OUTPUT -p udp -m owner --gid-owner skype -j REJECT
which I've put just after the conntrack default module, as 05_skype.py""" Skype restriction to avoid firewall block. Raw iptables commands. """ iptables(Firewall.output, "-p tcp -m owner --gid-owner skype -m multiport ! --dports 80,443 -j %s" % Firewall.reject) iptables(Firewall.output, "-p udp -m owner --gid-owner skype -j %s" % Firewall.reject)
For those who care or wonder: the reason why I hold a white
icepack to my cheek here at Debconf11 in Banja Luka, Bosnia
& Hercegovina, talk fairly little and try not to smile is
because I had one of my wisdom teeth removed this morning by one of
the local dentists.
Some might cringe at the idea of submitting yourself to such a
treatment in Bosnia, but I have to say that Doctor Sa a Dabi did
a splendid job, even though we weren t really able to communicate a
lot. Still, 45 minutes after I entered the office, I saw my tooth
on the table and was able to leave again.
My tooth had been building up an infection for several weeks,
and it was starting to become unbearable. Therefore I decided to
simply bite the bullet, after having seen the x-rays and judging
that it wouldn t be too hard to remove. It wasn t, the pain is now
minor, the swelling mostly under control, the drugs are
beer-compatible, and you all should just enjoy while I cannot talk
for tomorrow I ll be back!

The slides for our How to contribute and get involvedare now available at http://people.debian.org/~tolimar/talks/debconf-11/. Feel free to ask any questions we might have left unanswered via e-mail or irc chat (I'm Tolimar on irc.debian.org).
After some troubles I finally managed to write first usable application for MeeGo. The first thing I have choosen was intentionally simple as I more or less wanted to get used to Qt Quick. However I still think it can be useful (after some polishing), at least I used similar application on my older phone :-).
The application is meant for photographers who don't remember hyperfocal distance for all their lenses and apertures or want to calculate depth of field:
