Recently Jiri Eischmann posted a great blog post about ABRT improving Fedora Workstation - [cz] and [en]. I'm glad the work the ABRT team is a valuable source of data for many projects these days and thanks to their input, the UI of ABRT Server is getting new features for better filtering, queries etc.

Recently there was a discussion within Linux Foundation members to even use this statistics for evaluating quality of a certain project and using the data from ABRT as one of the sources for their quality equation. Check out Census Project if you want to know more.

Fedora 22, Plasma5 and Pidgin icon

I'm in love with Plasma5 in Fedora 22. So far it's a really great experience and all my previous issues that I had with KDE 4 seems to be gone. One thing that I was missing was a pidgin notification icon. After quick search I found this project that even though it is called Ubuntu Indicator works great with Fedora and Plasma.


Simply get the latest snapshot, autoreconf, ./configure, make and make install and there you go.

DevConf 2015 - Best talks

Hi everyone,

here are the best talks at DevConf 2015 (based on voting questionnaire published at www.devconf.cz)

The best 4 presentations are

1. shellshock! (Huzaifa Sidhpurwala)
2. Docker Security (Dan Walsh)
3-4. Pushing Puppet (to it's limit) (James Shubin (purpleidea))
3-4. Write Yourself an Annotation Processor (Ladislav Thon)

Congratulations folks!

All these talks are recorded. This year we've managed to record an amazing number of 138 sessions - all available on RedHatCzech Youtube Channel.
It's been some time after DevConf 2015 (www.devconf.cz) but due to ton of work after conference and some travel, vacation time and eventually sickness as well I got to write this post-conference report now. The conference was hell lot of work again and it's great that it is still based mostly on volunteers helping with the organization. And that's the way it should be! Couple people asked me or Jiri Eischmann - why didn't you organize this or that? (registration, competition, feedback forms after talks) and my answer was - we've setup a conference framework, we coordinated various activities but the rest is up to you/others. Even the schedule was collaborative effort between various groups who picked up sessions they were interested in and lined them up for themselves. That way we had people looking at Container track, QA track, Networking and Virtualization track etc. I think it worked great - thanks to this approach we had OpenShift folks comming up with their own competition - Winter of Code. They had around 30+ submitted apps and gave away 3 Nexus tablets to winners. Some projects asked us to booth tables - they got them and thanks to that we had 3D printing booth, JBoss Mobile booth, Rpi&Andruino desk etc. Some folks had this idea of streaming all talks directly to youtube. We've introduced them to people at university and let them figure everything out - well, we were little sceptical about the streaming and thus we haven't really announced it before the conference and turned out to work really great. So DevConf stayed and will stay a conference for Developer organized by Developers!

I received several great comments about the venue. We've moved from Masaryk University who's venue became really small for us to Brno University of Technology where we got not only bigger rooms and more rooms, but also more space around the rooms. Although some people commented that it was still crowded especially during the first day, we wouldn't be able to fit that many people in the old venue. We've used 9 different rooms at the venue and that way we could set up 8 parallel tracks for sessions and workshops. Honestly, I was little worried about the set up and especially the number of parallel talks. My worry was that we wouldn't be able to avoid disappoitment for certain presenters where noone will show up for their talk or hackfest. Well, turned out that the attendence at conference was really great and every presenter I talked to was happy about the number of people comming to their session. Another twist was the choice of speakers. DevConf originally was a starter conference for new faces, folks who didn't have a chance to present on big events like FOSDem or LinuxCon. On the other hand we've received submissions from folks were we knew they were going to deliver awesome talks. My preference was to those beginners. Not that we didn't find space for folks like Dan Walsh, Lennart and others but we've balanced it out. I've seen only couple negative comments about quality of talk - and it was mostly due to audio issues not the technical level of the talks. Putting that the other way round, comments I've seen valued the technical level of the talks and the deepness speakers went to. One comment was stating, that it was obvious that speakers are the technical experts and they know their stuff!

So let's get thru some numbers. This year we had 156 different speakers and on the original schedule 164 talks and workshops. We've pretty much doubled the size of conference compering to last year! And I have to appologize that coming up with the schedule took so long again, but we were trying hard to at first, get various teams to line up their own schedules and at second, please everyone and figure out a way how to merge talks, move them from sessions to workshops or other way round. I know it wasn't ideal in all cases and there were couple glitches but - it's a developer conference and it wouldn't be fun with things working out great all the time!

The attendence to the conference was great. Jiri counted more than 1000 people during Friday and Saturday. His estimate for Friday was going up to 1200! If you ask me about precise numbers - we don't have them. But there's around 400 people for signed up of sched.org and created their custom schedules. On that list, I see people from various interesting companies, interesting open source projects, countries around the world (based on their private email addresses) and of course, huge number of folks from Red Hat. And of course I was glad that couple good old friends showed up - people who love coming to DevConf and despite the weather that we tend to get in February they always come to Brno. Sched.org offers a full demographic report (for additional fee that we haven't paid) but I doubt this will be anyhow more interesting.

I'm preparing a follow up post with interesting links. We have slides available, videos of RedHatCzech youtube channel and several good blog posts. Stay tuned, it will come out soon.
Developer Conference has been started already 7 years ago as a conference that wanted to allow local folks from various open source projects to present their work, ideas and plans. It never had an intention to become an international event, with hundreds of sessions and workshops. Well, this year it again got way bigger that what we've planned.

Last year we've hit the limit at the venue we have always been using. The rooms got crowded, the corridors were packed. It was still great event but we've started discussing moving the conference to new place. Luckily Red Hat setup a closer collaboration with Brno University of Technology and we got an option to use their venue for this year.

The lecture rooms are all recently build up and there's more of them. We have more space for booths, refreshments or even hallway conversations. Well, so why not to use all of that space!

I'm not sure if other event organizers are dealing with the same - but most of the talk submissions appear minutes before the deadline! :-) .. right after this deadline, we've realized that creating the schedule needs more people involved who can pick up tracks and make up the order of talks, avoid conflicts of interest etc. It was tough and we can't please everyone .. sorry folks! Big thanks to all who worked on the schedule and help me to line it up.

It's packed - 155 sessions, same number of speakers, lots of volunteers (we still need more, contact me if you'd like to help), 5 parallel talks tracks, 3 workshop tracks and all this in 3 days including great party at our favorite place - Fleda. If you haven't seen the schedule yet, check it out.

So if you have free weekend, want to see some good developer talks or help with your favorite projects - travel to Brno!

BTW, you can still win a tablet! Just hack up some cool app that runs on OpenShift and submit it to OpenShift Winter of Code!
Winners will be announced on the OpenShift session on Friday at DevConf.


By mistake I've disabled all network notification .. I'm especially interested in my VPN notification cos I tend to mistype my password. Here's a quick trick how to re-enable all disabled notifications

gsettings set org.gnome.nm-applet disable-connected-notifications false
gsettings set org.gnome.nm-applet disable-disconnected-notifications false
gsettings set org.gnome.nm-applet disable-vpn-notifications false

How to download MP3s! From youtube ..

It's fairly easy, just run `youtube-dl --extract-audio --audio-format mp3 -l ` and it's all yours!

OpenShift Winter of Code for DevConf 2014

If you still don't know what you're going to do during Christmas holidays here's a quick tip. Code and win! The OpenShift team is organizing a competition for Developer Conference 2014 - OpenShift Winter of Code. The most interesting, unique, entertaining app will be shown during the conference and the winner will get Nexus tablet!

Not coming to Devconf? Doesn't really matter, you still have a chance to participate, your app will be shown and conference and you will get your price as well as invitation for Devconf next year!
Here's what I did

$ yum install docker
$ docker pull mattdm/fedora

and I waited and waited ..

Well, thankfully I'm not that patient, so I interupted that, looked for docker help to figure that this is really not *that* docker

So this is a note to myself

file /usr/bin/docker from install of docker-io-0.7.0-14.fc19.x86_64 conflicts with file from package docker-1.5-9.fc19.x86_64

and all I ever wanted is

$ yum install docker-io
$ systemctl start docker.service
$ docker pull mattdm/fedora
Hi everyone,

the Developer Conference 2014 Call for participation is still open. We are seeking for presentations for developers and admins as well as workshops focused on the same group. Last year we've covered several interesting topics from kernel space, developer tools, desktop, midlleware and cloud projects. For the upcoming conference we already have couple interesting people from Fedora community, Red Hatters or developers of other projects.

The conference will be again hosted at Masaryk University in Brno Czech Republic. Last year the attendance was around 600 people and we expect the same number of people this year as well. THe call for papers is open till the end of this month, the schedule will be available around Christmas and the actual conference starts on Friday February 7th.

More info is available on our new and redesigned conference pages www.devconf.cz.
