Looking back at FrOSCon 2011

Last weekend the 6th FrOSCon took place in St Augustin. Once again it was a nice event, but this time we tried something new: A Fedora Activity Day (FAD) as part of the conference.

I arrived at St Augustin on Friday around 7 p.m.. A lot of people were already there and it was nice to meet a lot of friends and many of the typical suspects again. Unfortunately we could not yet build up the booth as Robert, who had the event box and the banners with him, was stuck in heavy traffic jam. When he finally arrived at half past 8 we quickly prepared the booth before we left for dinner with our friends from Xfce.

We decided to go to Bonn because Christian lives there and he recommended an Ethiopian Restaurant. Of course we were a little skeptic and made bad jokes (“Ethiopian? We’ll go home hungry!” and alike) but Roha Café has completely proven us wrong: Nice atmosphere, friendly people and awesome food that is eaten just with the hands by wrapping it in bread. We were nine people and ordered 3 different plates for 3 people each but we didn’t manage to finish them because we were completely filled up. Each of us had 2 drinks, some also had a delicious Ethiopian coffee after dinner and in the end the bill was ridiculously cheap (less than 14 EUR per person). So if you ever happen to be in Bonn, go to Roha Café.

Some of us wanted to go wild afterwards and decided to go for more drinks, but as FrOSCon opens doors at 8:15 a.m. on Saturday, most of us decided to go back to the hotel. I went to Cologne with Enrico because I stayed at a friend and commuted to St Augustin.

On Saturday we had a German Translation team leaders of GNOME, Xfce and LXDE. We had Hendrik Richter and Christian Kirbach from GNOME, Fabian Nowak and me from Xfce and me again for LXDE. Even though the meeting was a little short I consider it very successful. Our goal is to have consistent translations throughout the different desktops and it was nice to see we agree on so many things, even on tiny details. There is still a lot of work to do but harmonizing our translation guidelines is a first step in the right direction.

Saturday was the better of the two days: The number of visitors was lower than last year (somebody even said it was all time negative record) and Sunday was even worse than Saturday. I don’t think it was that bad, we had visitors at the Fedora booth most of the time, but Sunday definitely could have been better. Not only the exhibition, but also our FAD.

The FAD began at 10:00. Benedikt gave a talk about his “Fedora Home Server”. The title mimics the “Windows Home Server” and so does the feature set of the server. Of course you can add more services and the audience came up with interesting ideas. After that Robert delivered a talk about SELinux. It seems SELinux still causes people a lot of headache and thus a lot of people came to Robert’s presentation.

Not many seats were left when Robert gave his SELinux Talk at FrOSCon 2011

Next up was Anreas with a talk about Func, the Fedora Unified Network Controller. It was perhaps the most entertaining talk because Andreas made a dry topic a lot of fun, especially when he started showing stuff on not on a demo machine but a real production environment.

After a short lunch break I gave two more talks, one about remixing Fedora and the other about RPM packaging. I hardly had the latter prepared, I just used the slides from one of my many previous talks about packaging and we made it more like a workshop. People liked this a lot: It definitely makes a difference if you just go through some slides or if you have a RPM package or a live CD ready at the end of the workshop. The audience was very experienced, most of them already were Fedora users or had at least used it, so we could even address advanced topics.

Having a FAD or a FUDCon as part pf another event is always a difficult decision. On the one hand a lot of people there, both contributors as well as visitors. The contributors don’t need to pay for travel again and you reach an audience that you would not reach with a Fedora-only event. On the other hand people get distracted by the main event. There are many other talks and so much to see. Because all contributors want to attend either the Fedora event or one of the other talks, it’s difficult to have enough booth personnel all the time. So if you you are hacking on something special and you just want to get things done ™ it is maybe better to meet somewhere in the middle of nowhere to not be disturbed.

Nevertheless I think this FAD was worth it: It was not a hack fest but more like a one day mini-FUDCon full of talks and as such it makes perfectly sense to have it at FrOSCon: FrOSCon is famous for it’s talks while the exhibition is secondary. We managed to address a new audience and raised awareness for Fedora.

I’d like to thank all Fedora contributors who helped us to make FrOSCon 2011 a successful event, namely (and in no particular order)

  • Benedikt for his 1st Fedora talk
  • Raphael for doing booth service
  • Dominic for his dry humor and for delivering Fedora swag to Hamburg for Software Freedom Day
  • Christian who also is part of the FrOSCon team and helped us a lot with the organization
  • Sven for doing endless hours of booth service while we held our FAD
  • Jens for coming to St AUgustin and helping out even though his spare time is very rare
  • Sirko for the FAD posters and the Inkscape workshops
  • Gerd for showing up so I finally had the chance to finally meet my sponsoree in person after 2 years
  • Andreas for his brilliant and entertaining talk about Func
  • Robert for bringing all the booth material to St Augustin and delivering his SELinux talk
  • Sandro and Marcus for showing up although they were not officially part of the Fedora team this year
  • Zoltan for sending us flyers and Cheat Cubes

Meet you at the Desktop Summit

Desktop Summit 2011 BannerI initially planed to go to the Desktop Summit on Thursday because of our Kolab track on Friday, but then I changed my mind because of the talks and the Lightweight Desktop Summit, the annual meeting of the LXDE Foundation. I arrived at Berlin at 3 pm and was at the venue at 4 o clock. It is nice to see so many friends and a lot of Fedora and Red Hat contributors here. If you are not yet in Berlin come here NOW!

Linux New Media to ship thousands of Fedora DVDs

F15 Multiboot DVD
F15 Multiboot DVD with GNOME and KDE

As some of you might know I started writing for the German Linux Magazin in April. I am now in the lucky position to know quite a few people at Linux New Media and one of them asked me if I had an idea for the DVD they ship with their magazine. Of course I had: A Fedora Multiboot DVD.

First the editors were a little skeptic: Fedora is not that popular in Germany and many people still think it’s too bleeding edge, so Linux Magazin usually ships with save bets like Ubuntu or OpenSUSE. But when I told them about the new amazing features of our Multiboot media such as automatic detection of the CPU architecture and offered them to do a custom German spin, they agreed. So I made a prototype and it has taken a shine to them. 3 days later they asked for an English version, so it now ships not only with the German Linux Magazin but also with the English Admin Magazine. Look out for it in

  • Germany: Linux Magazin is in stores as of today.
  • UK and other European countries: Admin Magazine 04/2011 to be released on July 17th.
  • North America: Admin Magazine to be released on August 12th.
  • Australia and New Zealand: Admin Magazine to be released on September 12th.

I was told not to mention the exact number of media but trust me, it’s huge. It’s more media than the ambassadors produced for the last 3 or 4 Fedora releases worldwide.

And yes, I am fully aware that this media violates several guidelines and policies.

  • It is a re-spin with updates included. We usually don’t to this but to conform to legal requirements, I uploaded the list of source packages to the correcponding-source git repo.
  • It is a custom spin because the package selection is slightly different from the usual GNOME and KDE spins: It includes LibreOffice and for space reasons I had to leave all games out.
  • The isolinux background is the Fedora 15 one but branded with the logo of Linux/Admin Magazine. However this only affects the DVD but not installed systems.
  • I dared to call GNOME “GNOME” instead of “Desktop” in the boot menu. I guess I should just have called it “Desktop” and tell confused people to mail advisory board list to complain.
  • I didn’t ask the Spins SIG but as the Spins Wrangler I ‘approved’ it myself. There really was no time for discussions, the images had to be ready and shipped to Munich in less than 36 hours.
  • I didn’t ask the board either. I know how discussions on a board level tend to become and there really was no time.

Speak up if you think I have done harm to the Fedora Project!

Video thumbnails in Thunar

As you might know thumbnails in Thunar are generated with tumbler. For obvious reasons the tumbler package in Fedora cannot include the tumbler-ffmpeg plugin. By popular demand I now rolled an add-on package called tumbler-freeworld. When installed, this is what it looks like:

If you are a packager at RPM Fusion, please review the package. Fedora’s Xfce users will appreciate your help.

GNOME developer quote of the day

I am no longer using GNOME but Xfce and this has nothing to do with GNOME Shell. I already switched a long time ago. But as the (co-)maintainer of several terminals in Fedora, I wondered how to enable users to easily switch their default terminal emulator in GNOME 3.

In the past users could just select the their favorite terminal in gnome-default-applications-properties. Some things required additional configuration: For a mail client the system needs to know the command to compose a new mail or to add attachments and for a terminal emulator an option to run something in a terminal is required. Developers could pre-configure these values with an xml file in $(prefix)/gnome-control-center/default-apps.

When I asked how to do all this in GNOME 3, Bastien (who helped to invent this nice mechanism in GNOME 2) after a little back and forth told me how things work in GNOME 3. They don’t…

Because we’re not designing a desktop for people who like to choose their own terminal emulators.

This “We are not designing a desktop for people who …” has become a new meme. GNOME 3 is not designed for people

and many other people I forgot. If GNOME continues to narrow down their target audience like this, I wonder if there is actually somebody left.

Simple tasks like selecting a preferred application are made very hard just to then claim “This is something only hackers do”. In the past one could just remove the accessibility or bluetooth icons from the panel by not starting them, now one needs to write extensions for that purpose. One even needs an extension to move the clock. But wait: Is GNOME 3 designed for people who know how to write extensions?

If you think that GNOME is still a nice desktop after all and should not become too simplistic, please support my RFE by adding your two cents. Too bad voting in GNOME’s bugzilla is disabled.

Announcing the Kolab Server 2.3.2

I’m sorry it took so long, but good things take a while. I am relieved the release is out because now that the problems with FreeBusy are solved, the 2.3 series offer the same functionality as 2.2.4  – plus much more of course.

New features

The update to postfix 2.8 brings a lot of new features like postscreen and multi-instance support. However none of them is enabled by default and old configuration files continue to work. Have fun while exploring the new possibilities, we will make use of them in the next major release.

Bugfixes

Most of the bugfixes affect Kolab_* packages such as Kolab_FreeBusy:

  • apache-php: Security update fixing various CVEs
  • Kolab_FreeBusy: Generating free/busy cache works again
  • Kolab_Resource: Answers from resources no longer contain extra “\r\n\r\n”
    characters
  • Kolab_Server: IMAP connection issues fixed
  • Kolab_Storage: Webclient no longer hangs if freebusy triggering/retrieving
    hangs
  • kolab-webadmin: Listing of sub-folders and sub-calendars was fixed
  • kolabd: Fixed an imap annotatoin so SyncML can sync contacts
  • php: Security update fixing various CVEs
  • postfix: Security update to 2.8.3. This also brings a lot of new features
  • z-push: New version with many bug fixes, rebuilding with prefixes other than /kolab fixed.

For a complete list of changes please refer to the release notes.

There are still two bugs in freebusy and the resource management:

  • Issue 4730: Generating free/busy cache broken in server 2.3.0
  • Issue 4731: Answer from resources contains extra “\r\n\r\n” characters

These will be fixed in 2.3.2 and we will offer packages for testing next week. Please report bugs in our bug tracker.

Development roadmap

As 2.3.1 was released two weeks after 2.3.0 and I’d like to stick with the two-weeks cycle. This means that the Kolab Server 2.3.2 will be released on Friday, May 13th. Yes, this is an unlucky date, not because I’m superstitious but I will be busy. This might even mean I will release earlier.
