Going to FOSDEM 2013

I've just confirmed my flight and hotel bookings for FOSDEM 2013, so I'm looking to meet all great people there again.

This year my schedule is not that packed as I have no talks (Weblate lightning talk was not accepted) and also there will be no big phpMyAdmin team meeting, so get in touch if you want to discuss anything with me.

As most of the rooms still don't have a schedule, I can't give you hint where I will be present, but I definitely won't miss Friday beer event and Dieter's talk about phpMyAdmin in MySQL room. The rest pretty much depends on who I will meet :-).

Free software plans for 2013

Year 2013 has just started and it's time to think how to spend my free time during this year.


Weblate was my toy project number one in last year and I expect it to stay for next year as well. I have several ideas for new features, but all that depends on free time. I will most likely spend my hackweek on that as well.


I think my involvement will stay at about same level at phpMyAdmin - doing few random bugfixes, mostly security ones, taking care of infrastructure for translations and wiki and mentoring few GSoC students.

Gammu and Wammu

Gammu and Wammu has not seen much activity from me in past year and it will probably not change. I don't use the program anymore and this pretty much limits my interest in adding new features. In case somebody active will pop up on mailing list, I'd be happy to transfer the project ownership.

Mobile apps

I'd like to make some progress here, I was also thinking about making some of them working on Android as well, but this involves lot of learning and time is always an issue here. Anyway this might be good challenge for hackweek as well.


No changes expected here :-).


I consider pretty much anything else from my software projects abandoned or finished.

Weblate 1.3 at SUSE Studio

Finally, I've managed to update SUSE Studio images with Weblate to recently released 1.3. So you can now fetch there various images for your virtual machines or clouds.

There is also new support for SUSE Cloud or OpenStack in SUSE Studio, so you can enjoy these as well.

Within this version, I've upgraded the system to openSUSE 12.2 and included MTA in the image, so that you can send out registration emails.

You can find more information about Weblate at http://weblate.org/.

Weblate available as BitNami stack

Weblate is now available for your cloud or virtual machines - BitNami has published Weblate stack.

BitNami stack allows you to install native application on Linux or Mac OS X as well as provides images for virtual machines or to be run within cloud (some of these options are still waiting to be built).

Also I wanted to finally release SUSE Studio images, but all I get out of that are HTTP 500 errors (whenever I tried since Friday). Luckily today I at least managed to build one image to test. This allowed me to reproduce bug with broken registration as mailserver was missing in the image.

Key signing done

As I've mentioned before, there was a keysigning party in Prague yesterday. Though we were afraid that not so many people will arrive, in the end I have signed 19 keys and assured 13 people for CAcert.

The nice outcome of this is that I can now give up to 25 points when assuring for CAcert and altogether we are able to give you over 50 points in the Prague SUSE office.

Unfortunately this also reminded me my problems with Unicode on CAcert and quick look at the bug tracker showed me that my bugs 769 and 770 are still open, valid and did not receive any attention :-(.

PS: Of course after key signing, we had some fun with the openSUSE beer.

Key signing party in Prague

Tomorrow (Thursday 15th November), there will be a PGP key signing and CAcert assurance party in Prague. It will be held in SUSE offices and it will start at 17:00.

If you are interesting in having your PGP key signed, bring papers with your key fingerprint (you can use for example these slips) and some government issued ID. For CAcert assurance it is recommended to bring printed out assurance papers (you can get them from CAcert website) and of course IDs as well.

You can find more information on Facebook or Google+ event pages.

oSC12 wrap up

As the openSUSE Conference and all related events are over, it's time to share my thoughts how it was.

This was actually first conference ever where I helped with organizing, so it was quite new experience for me. Week before it has happened I expected quite a lot of problems, but in the end everything went more or less smoothly.

Having something like 700-800 visitors is IMHO great for first year of LinuxDays, even though it has been collocated with other conferences. Most people came on Saturday and there were less of them on Sunday. Maybe it was result of the party, which lasted for many of them till early morning (I've left around 1 AM and there were still lot of people drinking).

Besides organizing stuff, I also had my own talk about Weblate. Unfortunately not much people has attended it, but those who did gave me some valuable feedback which will be reflected in next Weblate release. Anyway if you want to see my slides from this talk, they are now available on my website.

Bootstrapping awesome in Prague this weekend

This weekend there is going to be a lot happening in Prague - awesome combination of four conferences will happen here.

I'm sure this will be really a great event with lot of interesting things on schedule. Even if you are not interested in technical stuff, future media track might be interesting for you. And of course the event includes huge party on Saturday evening (and welcome party with pre-registration on Friday)/

Anyway if you will be around, you can meet me somewhere there, usually within organizers crew.

PS: There also nice summary of latest news available now.

Weblate hacking #5

Last day of Hackweek VIII is over and I think Weblate is pretty much ready for 1.2 release.

Today I continued to analyzing performance and did few optimizations of some frequently used code paths. There is still lot of area for improvement, but I think Weblate is now fast enough for daily usage on even quite big projects.

Rest of the day was spend by looking at various questions which people have asked me and distilling that into documentation. The most extended part were frequently asked questions, which now includes some hints for setup.

Of course the demo server is running latest and greatest git version, I will probably push it soon to http://l10n.cihar.com/ as well.

Weblate hacking #4

Fourth day of Hackweek VIII was for me again mostly spent on Weblate. This time there are no new nice features, but rather general improvements to the code.

First task was to add support for django-registration 0.8. Originally my plan was to support both 0.7 and 0.8, but that proven to be too complicated so Weblate now requires 0.8, which brings quite a lot of differences in API.

Later I've installed django-debug-toolbar and looked at some bottlenecks in some hot paths. This resulted in few optimizations of translations merging and new caching for translation stats. This turned out to be too expensive for bigger translations and caching these can save few seconds on page load.

I will probably focus more on performance tuning tomorrow as I don't plan to add any new features to 1.2 release.
