Will I write such a code ?
Calling "[Microsoft] managed to make the kernel more offensive to half the population" is too much of an over-reaction, to, what is just a lame joke of a programmer trying to be funny. There is no need to drag Microsoft's name here, for the same reason, why we don't accuse The Linux Foundation of propagating male supremacy ideas, when Linus Torvalds says "Do you pine for the days when men were men and wrote their own device drivers?"

Moving on to something completely different
Last month, I got a new job! After three years in the openSUSE Boosters team, I joined the SUSE Cloud team. I'm now working on OpenStack and on SUSE Cloud itself. Quite a big change!
I had planned a long time ago that the release of GNOME 3.0 would be a good time for me to look at what's next. When it went out, I actually took a few months to cool down a bit (it was pretty much needed), and also have some good fun with openSUSE. But after a while, this desire of trying something new came back: I had been working on the desktop for nearly ten years, and on a distribution for four years. Those were exciting years, but at the end, it started to feel like, you know, work
. I wanted to stay involved in GNOME, in the free desktop in general, in openSUSE, in cross-distro collaboration: this is not just work
and this should not be just work
. I didn't want to slowly move to doing stuff while not caring anymore. This is how I found out that I needed to go back to the early days and contribute in my free time again :-)
There was still the question of, well, work
. I started looking around, and I had some good discussions with several people about what to do next (thanks to everyone who took some time for this!). i must admit I changed my mind several times. I was not necessarily looking for a developer position (quite the contrary, actually), as I knew that for me to be motivated for a new project as a developer, the project had to be one that I could care about, one that has a free software community around it and one that would get me out of my comfort zone (so not on the desktop nor on a distro) — yeah, not easy :-) But at some point, SUSE had this cool developer position related to OpenStack. Good timing. (Btw, we're still hiring!)
It's been great so far; of course, you need to ignore the buzz words ;-) I wanted a new challenge and I wanted to get out of my comfort zone, I got served: new project, new community, new code, etc. It didn't help that the hard disk in my laptop decided it was the perfect moment to die, and that Lenovo took weeks to send me a replacement disk (finally got it yesterday). But now I'm all set, so let's have fun!
GNU screen window title and SSH
If you want to keep track of all your GNU screen sessions, it's helpful to set the window title to the current machine you ssh'd into. One way to achieve this is to put this into your .zshrc (.profile should work too): # Set/reset hostname in screen window title SSH'd machine: if [ $TERM = "screen" … Continue reading GNU screen window title and SSH
Ative e use o IPv6
Ativando o IPv6 em seu sistema operacional
O IPv6 já vem habilitado por padrão nos sistemas operacionais modernos. Se você têm uma versão atualizada de Windows, Linux, MacOS ou BSD, o IPv6 estará ativado.As páginas a seguir mostram como verificar se esse é seu caso, e ativar o IPv6, se for preciso:
Obtendo conectividade IPv6 e usando o novo protocolo
Uma vez que o IPv6 esteja ativo, caso seu provedor de acesso Internet já suporte IPv6, a configuração do seu computador provavelmente se dará de forma automática. Consulte seu provedor e pergunte se ele já tem IPv6. Se não tiver, pergunte quando terá!A maior parte dos provedores de acesso no Brasil (em 2012) ainda não ativam o IPv6 para usuários domésticos.
Se você quiser testar o novo protocolo, sua melhor alternativa é usar um serviço gratuito de túneis, chamado de Tunnel Broker, para obter conectividade. Há três opções que recomendamos, e as instruções estão nos links a seguir. Os melhores resultados à partir do Brasil são obtidos com a primeira opção, o SixXS:

Lembre-se, sempre:
De acompanhar o Cronograma de implantação do IPv6 no Brasil:

Midterm completed
I successfully completed my midterm evaluation, its awesome! I just can't stop staring at that figure in my account :D
Till now, I have completed integration of Karma with Twitter, Bugzilla, planet openSUSE and Build service. The Build service part though complete, still needs modifications due to some troubles in the approach that I am following. Using the api and getting commit history or parsing the changes file associated with each package both have some side effects. So I'm still looking for a better solution.
Then I also have plans to reward people on forums. People providing technical help to others deserve to be rewarded I think. Though I haven't researched on how to go about it, so I won't commit anything but lets hope it works out.
And karma plugin is deployed on Connect and working, so pull in that widget on your dashboard or your profile and have fun. I made a post about the karma widget not working but I completely forgot to post about the issue being resolved, my bad :)
So try it out, and please let me if you like it or dislike it even or leave any suggestion for me, if you think I can make it better in any way.
You can even check my code at Karma. Let me know what you feel.
[gsoc] osc2 client – summary of week 8
Hi,
here’s a small summary of the 8th (coding) week. The last days I
was working on getting build support into the osc2 library. I just
checked in a BuildInfo and Builder class (+ testcases). Here’s a
brief example how they can be used:
# example how to use the Builder class
builder = Builder(su_cmd=Builder.SUDO, root='/var/tmp/build-root')
builder.rpmlist = '/path/to/rpmlist'
builder.dist = '/path/to/buildconfig'
builder.without = 'feature1'
builder.without += 'feature2'
builder.arch = 'x86_64'
# run the build:
builder.run('/path/to/osc.spec')
# this executes:
sudo /usr/bin/build --arch x86_64 --dist /path/to/buildconfig \
--root /var/tmp/build-root --rpmlist /path/to/rpmlist \
--without feature1 --without feature2 /path/to/osc.spec
Basically Builder is just a wrapper around the build script
(all options will be passed to the build script; if an option contains
a “-” character like “vm-type” it can be set like this:
“binfo.vm_type = ‘xen'” (a “_” will be replaced with “-“)).
Additionally here’s a small example how to utilize the BuildInfo
class:
# fname is a path to a spec file
binfo = BuildInfo('openSUSE:Tools', 'osc', 'openSUSE_Factory', 'x86_64',
filename=fname)
# print preinstall packages
for bdep in binfo.preinstall():
print bdep.get('name'), bdep.get('version')
# save binfo xml in a file
binfo.write_to('/path/to/file.xml')
The next thing on my TODO is the fetcher and cachemanager code.

openSUSE 12.2 RC1!

Το openSUSE 12.2 Release Candidate 1 είναι πλέον διαθέσιμο για να το κατεβάσετε.
Αποκτήστε το!
Κατεβάστε το από το software.opensuse.org/developer. Ως συνήθως, μια λίστα από τα πιο ενοχλητικά σφάλματα διατηρείται και μπορείτε να τη δείτε και / ή να υποβάλετε ένα νέο στο Bugzilla.
Αναβαθμίσεις!
Από τη Beta 2, οι ακόλουθες αλλαγές έχουν γίνει:
Ο grub2 ενημερώθηκε στη 2,0 τελική έκδοση. Το branding του επίσης ενημερώθηκε. Υπήρξαν διορθώσεις για το udev, και τα udisks και udisks2 για την απόκρυψη των LVM κατατμήσεων RAID και έγιναν πολλές διορθώσεις στο autofs. Πολλές διορθώσεις ήρθαν στο systemd.
Πολλά πακέτα περιλαμβάνουν τώρα systemd αρχεία εγγενώς, και έτσι αυτά αφαιρέθηκαν από το ίδιο το πακέτο του systemd, για παράδειγμα για το Plymouth, το οποίο έχει ενημερωθεί στην έκδοση 0.8.5.1. όπου το rpm καλεί τώρα το systemctl daemon-reload όταν εγκαθιστά νέα init scripts.
Στον τομέα της διαχείρισης των πακέτων, το zypper ενημερώθηκε στην έκδοση 1.7.3, φέρνοντας καλύτερο καθαρισμό και υποστήριξη για διπλό πλάτος γραμματοσειράς. Το OSC, ο Open Build Service πελάτης, αναβαθμίστηκε στην έκδοση 0.135.1, με πολλές διορθώσεις και προσθέτοντας πακέτα στήριξης για archlinux. Στο YaST UI διορθώθηκε ένα segfault.
Ενημερώθηκε ο gcc στην έκδοση 4.7.1, διορθώνοντας πολλά σφάλματα του gcc47. Ενημέρωση για το automake στην έκδοση 1.12.1 επίσης διορθώνοντας επίσης αρκετά σφάλματα. Αναβαθμίστηκε και το OpenJDK, στην έκδοση 1.7.0. Το vim είναι τώρα στο 566 patchlevel με πολλές μικρότερες διορθώσεις. Το Kiwi, που χρησιμοποιείται στη διαδικασία δημιουργίας εικόνας λογισμικού, έλαβε επίσης πολλές διορθώσεις που του επιτρέπει πιο αξιόπιστη ανάπτυξη στο openSUSE 12.2.
To ALSA έχει λάβει πολλές μικρές διορθώσεις, και ένα segfault βρέθηκε και διορθώθηκε. Ενημερώσεις έγιναν σε μεγάλο αριθμό των πακέτων, μια μικρή επιλογή είναι τα VirtualBox, nmap, R, pango, Go, phpmyadmin, vym, aria2, GnuTLS, mariadb και jedit. Το Xorg είναι τώρα στη τελευταία έκδοση 1.12.3, και πολλές διορθώσεις έγιναν στα πακέτα του πηγαίου κώδικα.
Tα μεγάλα γραφικά περιβάλλοντα εργασίας ενημερώθηκαν επίσης.
Το KDE έχει ενημερωθεί στην τελευταία έκδοση, 4.8.4, φέρνοντας βελτιώσεις σε ολόκληρη την επιφάνεια εργασίας. Ένα σοβαρό πρόβλημα με το Soprano που επηρεάζει πολλά προγράμματα του KDE έχει επιλυθεί.
Στο GNOME έγιναν πολλές μικρές διορθώσεις. Τα Empathy, Tracker, Pidgin, Rhythmbox, gnome-bluetooth, έλαβαν σημαντικές ενημερώσεις.
Το Lxpanel του LXDE έχει ενημερωθεί στην έκδοση 0.5.1, και διορθώθηκε ένα σφάλμα στο xfdesktop του XFCE.
Το LibreOffice βρίσκεται τώρα στην έκδοση 3.5.4.6, ένα πρόβλημα στο Gimp βρέθηκε και διορθώθηκε, ο Chromium αναβαθμίστηκε στην έκδοση 22.0.1190, και έγιναν διορθώσεις στο εικονίδιο του Scribus για τη βελτίωση στη χρήση του στο GNOME.
Επόμενα βήματα!
Στο μήνα Αύγουστο θα δείτε εντατικές διορθώσεις σφαλμάτων, οπότε δοκιμάστε και αναφέρετε σφάλματα. Η τελική έκδοση έχει προγραμματιστεί για τα μέσα Σεπτεμβρίου και η RC2 θα είναι διαθέσιμη στις 2 Αυγούστου.
Οι συσκευαστές και οι δοκιμαστές θα πρέπει να γνωρίζουν ότι η ανάπτυξη του openSUSE 12.2 γίνεται στο δικό του branch, έτσι το Factory είναι πολύ μπροστά από το 12.2. Το δημόσιο 12.2 αποθετήριο θα ενημερωθεί στη συνέχεια με την RC2 και οι αναβαθμίσεις θα είναι διαθέσιμες σαν online ενημερώσεις.
Αλλαγές στο μοντέλο ανάπτυξης για το openSUSE θα εξακολουθήσουν να συζητούνται στην λίστα openSUSE-factory.

[gsoc] osc2 client – summary of week 7
Hi,
here’s a small summary of the 7th (coding) week. Last week
I was really busy with university stuff (it was the second
last week in the lecture period so I had to recap quite
some stuff) and didn’t manage to work much on the GSoC project.
I’m going work off the TODO this weekend.
