Flatpak and Endless OS at InstallFest Prague

I spent the last weekend in Prague attending InstallFest 2017. The event is called InstallFest because many, many years ago it started as an event where students could come and get help with installations of various Linux distributions. Times of installfests are gone and this event has transitioned into an open source conference with more practical focus.

The event has moved to a new venue – Faculty of Electrical Engineering of Czech University of Technology. It’s where Red Hat recently started a new open source lab. The venue was larger than the one in previous years and hosted 3 tracks + a small booth area.

I came to talk on two things – Flatpak and Endless OS. My Flatpak talk was on Saturday and got a 55-minute slot which seemed like a lot of time, but if you want to cover all the specifics of the technology, even 55 minutes is not much. The room was pretty full and the topic apparently stirred some attention. There was even one person interested in porting Flatpak to another distribution.

My talk on Flatpak

My talk on Endless OS was the first one of the second day. I only asked for a 25-minute slot which was just enough to make a brief introduction of the system. I also brought with me both Endless devices I have in possession – Endless One and Endless Mini. There were not as many people as at my Flatpak talk, but those who came seemed pretty interested. Almost none of them had ever heard of the OS and PCs before. They asked if they’d ever be available in Europe (which I couldn’t answer because I have no idea) or if you can connect extending hardware to the PCs just like to Raspberry.

As a side note, I was positively surprised how many people wore Fedora t-shirts at the conference.

Fedora, Red Hat 2017

Another edition of took place last week. It was already the second edition I didn’t organize. This year, I was involved in the organization even less, just helping with the program and serving as a session chair for one day. So I could enjoy the conference more than ever before.

snimek-z-2017-02-06-16-37-47 is still growing. This year, we had over 1700 registrations and ~1600 ppl actually showed up. This time, we also know for sure because it was the first edition when we did a registration and check-in. is growing into a smaller FOSDEM with more focus on open source enterprise technologies and I think it even covers this area better than FOSDEM. The number of talks and workshops was also a bit higher, I think (200-250).

The opening keynote was pretty interesting. Tim Burke, the VP of Red Hat, announced a focus on integration of different Red Hat products and this year he showed it had actual results. People could see a demo of using different Red Hat products from hardware provisioning to deploying an app to OpenShift from JBoss Developer Studio. I hope that we as the desktop team will be able to contribute to this. Fedora Workstation is a great OS for developers and it should be the best OS for developers that want to develop on Red Hat platforms. I’d love us to get to the point where starting to develop with Red Hat technologies is just a matter of a couple of clicks/commands.

Another highlight of the conference was Hans de Goede’s talk “Making Fedora run better on laptops”. Hans announced a new team which is part of the desktop team and which will work on better hardware support in Fedora and RHEL (with the focus on laptops). We will finally have laptop models which will be officially supported!

The desktop track took place on Sunday. I session-chaired it, so I was more or less obliged to watch it all 🙂 Matthias Clasen prepared a very good presentation on Flatpak. His talk and, in fact, the whole track was interrupted when the projector system broke down. Unfortunately it was a failure in one of the main hardware components which couldn’t be fixed immediately. Matthias had to carry on without the projector and I must say that despite all the difficulties he did very well and there was a lot of questions. Meanwhile we managed to get a backup room where we moved the track once Matthias’ talk was over. Unfortunately the room was much smaller and a bit hidden which might have had an impact on attendance. So not so many people had an opportunity to watch another interesting talk – “Fedora Workstation – removing obstacles to success” by Christian Schaller who outlined some of our plans for the official Fedora desktop edition.

The weather during the conference was extraordinarily cold and a new term – devconflu – was invented. But I really enjoyed it, just had to give up FOSDEM for it. I was not up for another Hat internal meetings+FOSDEM this year.

BTW all the talk recordings are already online. Check out the Youtube channel.

GNOME 3.22/KDE Plasma 5.8 release party in Brno

Last Thursday, we organized a regular Linux Desktop Meetup in Brno and because two major desktop environments had had their releases recently we also added a release party to celebrate them.

The meetup itself took place in the Red Hat Lab at FIT BUT (venue of GUADEC 2013) and it consisted of 4 talks. I spoke on new things in GNOME 3.22, our KDE developer Jan Grulich spoke on new things in Plasma 5.8, then Oliver Gutierrez spoke on Fleet Commander and the last talk was given by Lucie Karmova who is using Fedora as a desktop in a public organization and shared her experiences with the Linux desktop.


After the talks, we moved to the nearby Velorex restaurant to celebrate the releases. The whole event attracted around 25 visitors which is definitely above the average attendance of our meetups. Let’s see if we can get the same number of people to the meetup next month.

Last, but not least I’d like to thank the Desktop QA team of Red hat for sponsoring the food and drinks at the release party.

We’re looking for a GNOME developer

We in the Red Hat desktop team are looking for a junior software developer who will work on GNOME. Particularly in printing and document viewing areas of the project.

The location of the position is Brno, Czech Republic, where you’d join a truly international team of desktop developers. It’s a junior position, so candidates just off the university, or even still studying are welcome. We require solid English communication skills and experience with C (and ideally C++, too). But what is a huge plus is experience with GNOME development and participation in the community.

Interested? You can directly apply for the position at or if you have any question, you can write me: eischmann [] redhat [] com.


Red Hat 2016 is coming 2016 is just around the corner (starts on Feb 5th). If you’re going to attend the conference, the organizers have prepared useful information for you. Check and especially the transportation page. If any of your questions stay unanswered, you can ask the organizer directly in a group chat for attendees on Telegram. The group chat will also be useful during the conference, but we will send important announcements there, attendees can share tips there etc.

Schedule of 2016 is out!

A couple of days ago, 2016 schedule has been published. It’s bigger than ever before. This year, we have over 200 talks and workshops! There aren’t many bigger events devoted to open source in Europe. And I can finally enjoy it more because after 4 editions (2012, 2013, 2014, 2015) I’m no longer the main organizer.

It takes a team of people to go through almost 400 submissions and make a schedule with over 200 of them. I put together desktop, Fedora, and CentOS tracks. So if you don’t like them I’m the one to blame 😉

Since there are many Fedora ambassadors coming to anyway, we’ve decided to organize an EMEA Ambassadors Meetup which will take place on Sunday afternoon. I hope to see any ambassadors as possible there.

Most popular email clients among Fedora users

In the desktop team of Red Hat, I’m responsible for development and Fedora/RHEL maintenance of apps which also include email clients Thunderbird and Evolution. It’s quite useful for me to have a rough idea what email clients Fedora users use. So I went ahead and asked them on Google Plus and Facebook and here are the results:



email-clients-fbThe results from Google+ are probably much more representative because they come from a much larger number of users. Facebook doesn’t support polls, so users had to answer in comments which resulted in much fewer votes. Polls in G+ only support 5 options, so if someone wanted to vote for a different client than web, Thunderbird, Evolution, Geary, or Kmail, they needed to write it in comments as well. It might have disadvantaged other clients a bit.

Web – this includes all web clients, vast majority of it is Gmail which seems to be by far the most popular email service among Fedora users. On Google+, web got almost 40% which is not a number that surprises me a lot. A fairly large portion of users doesn’t use desktop email clients any more, but it’s also not big enough to say that desktop clients are obsoleted. 2/3 of users still use desktop clients to access their mail.

Thunderbird – the most popular among desktop clients, it’s a solid email client with many years of development, and many users value its support for various platforms, so that they can use it on other OSes, too. The most mentioned weakness was (in)ability to be a good groupware client (calendaring, Exchange support,…). Some lost faith in Thunderbird after Mozilla announced it wanted to spin off its umbrella which many understood (probably wrongly) as killing it.

Evolution – the second most popular client is the default client of GNOME – Evolution. Clearly the most appraised feature of Evolution is its groupware nature and support of Exchange, it’s probably the only Linux client that reasonably supports Exchange. On the other hand, it lags behind Thunderbird in IMAP support and it’s Linux only. Like Thunderbird, it doesn’t have a big developer force behind it any more. Red Hat is currently the only one who invests in Evolution, unfortunately.

Geary – it’s the biggest surprise to me. Considering its author – Yorba Foundation – ceased to exist at the beginning of the year and Geary has been dead for months, it’s still pretty popular. It’s a modern client with really good support of Gmail, but if Thunderbird and Evolution don’t seem to face big future, chances that Geary will be further developed are currently minimal.

Kmail – another surprise to me, I thought the default client of KDE would be more popular, it may be caused by the fact that Fedora is primarily a GNOME distro, but it may also be caused by the fact that users have lost faith in it after many ups and downs in development after KDE 4.0.

Mutt – I expected Mutt to be in TOP6. A CLI client will never win popularity contests, but it has a fair amount of loyal users. Another CLI client Alpine only received less than half of votes.

Among other mentioned clients were Claws Mail, Sylpheed, Mu4e, Nylas N1, Lotus Notes, Pine, Zimbra, Seamonkey… but they each got fewer than 10 votes.

Linux desktop clients are not dead, they’re still used by majority of users, but none of the traditional ones has a larger community of contributors and very active development which brings poses questions about their future. It will be interesting to watch new approaches to desktop clients such as Nylas N1 which moves IMAP client to the server and provides just a really thin desktop client.
