DevConf.cz 2014

1 Comment

Developer Conference 2014 is finally over. The last two weeks were damn busy for me. Just a week before the conference I went to FOSDEM and it wasn’t just attending. I organized a bus with 40 hackers between Brno and Brussels, accommodation for 6 Fedora people, and pretty much the whole Fedora booth at FOSDEM + producing 400 t-shirts for CentOS guys and bringing a lot of other stuff from Brno for various parties. When I returned I didn’t have time to rest because DevConf.cz was just a few days away. This in a combination with very little sleep meant that I had a complete physical meltdown on Wednesday. Not only was I dead tired, but I also got some flu/cold. Then I just focused on surviving till DevConf.cz because as the main organizer I just couldn’t simply back off. So I just worked and slept and removed all stuffing between it and it worked :)

We put DevConf.cz just one week after FOSDEM which as I described above almost killed me. But it also had a lot of benefits. Most importantly, people from overseas could come for both events and spend the week between on internal Red Hat meetings in Brno. And a lot of people did. I wondered how many attendees would come this year. Last year, it was around 700, but quite a lot of publicity on the Internet and people mentioning the conference indicated it could be much more this year which could be a problem because the venue is not very large and half of the campus is under reconstruction.

And we did have a lot of attendees. The number from DevConf.cz 2013 was exceeded within two hours and the total number of attendees for the first day was nearly 900. The total number of unique attendees for all three days was around 1000 which was a significant increase from the last year. Especially on Friday, we were hitting the capacity of the venue. Several talks were completely packed. For example the ones about Docker and OSTree where you couldn’t even get into the room if you came too late. I didn’t attend many talks and when I found time to attend one I was usually called back by an urgent problem. Nevertheless, the general feedback I heard from other people was that the talks had even better quality than last year. I really liked the Fedora Day which was the third day of the conference. This attracted a lot of people from the Fedora community and I could actually meet maybe more Fedora contributors at DevConf.cz than at Flock.

I can’t rate DevConf.cz because as the main organizer I’m biased, but from the organizer’s perspective the event went quite smoothly which was mainly due to tireless help of dozens of volunteers without whom the event wouldn’t be possible and I thank them for that.

And DevConf.cz 2015? I’m already thinking about that. We improve the event incrementally based on feedback from attendees to make the event better every year. Some of the proposed changes such as making the talk slots shorter to have longer breaks worked very well and we’ve already gathered new ideas for the next year. We also will have to assess the venue. The cooperation with the university is almost ideal, the location is also very good, but if we want to accommodate even more attendees next year we’ll have to have more space. The reconstruction will be finished in summer and then there should be mid-sized rooms for smaller talk or workshop tracks available. We will see. The only significantly larger venue in Brno is The Brno Exhibition Area which would be a huge cost jump up and I still find university campuses more appropriate for developer’s events.

P.S. Videos of talks from the three main tracks will be online within a few weeks. We’re working on it.

DevConf.cz 2014 schedule is out!

Leave a comment

Last week, we published a schedule of Developer Conference 2014 that is going to take place in Brno on Feb 7-9th and I finally found time to write about it. The schedule looks IMHO very promising. There are around 100 speakers of 18 nationalities that will deliver 68 talks and 30 workshops and labs from 14 topics: cloud, databases, desktop, developer, Fedora, kernel, networking, security, server, software quality, storage, userspace, virtualization. The conference has been expanded into three days. The first two will be standard conference days packed with talks and workshops. The third day is devoted to Fedora. There will be Fedora-related talks in the morning and planning sessions and hackfests in the afternoon. BTW we still have available slots in the afternoon, so if you’d like to organize a session or hackfest, let us know.

But DevConf.cz won’t only be about talks and workshops. We’re also preparing a DevConf.cz party that will again be in the Fléda club. And there will also be a city tour with a great Canadian guide on Friday. And there are still more things in the works.

We have a special rate for conference participants in Avanti Hotel (and this time also in A Sport Hotel), but there are just a few left, so if you still don’t have accommodation, don’t hesitate.

Fedora Project at LinuxCon Europe 2013

1 Comment

I just returned from Edinburgh where we represented Fedora at LinuxCon Europe 2013. It was great three days. I arrived to Edinburgh Sunday evening and was welcomed by a typical Scottish weather – rain. Our local contact and host was Keiran Smith, a longtime Fedora ambassador and packager. Another ambassador representing Fedora at LinuxCon was Jon Archer who arrived in the middle of the first day, and Tony, a longtime local Fedora user who helped us fill the last position after one of ambassadors cancelled their trip to LinuxCon. There were much more Fedora contributors at LinuxCon: Tom Callaway, Ruth Suehle, Matthew Garrett, Thorsten Leemhuis, Daniel Veillard and others.

Our booth was between BlackDuck and oVirt&Gluster booths and was well attended. We prepared stickers, case badges, upstream community sticker sheets, badges, and Fedora Cloud flyers for LinuxCon attendees. They could also check out Fedora 19 and 20 on two laptops we had at the booth. We also wanted to showcase a Wayland session of GNOME in Fedora 20, but had problems with input devices, so the showcase was over very quickly :-)

LinuxCon is not an event to present Fedora to new end users although we met a lot of people who said that would try Fedora after visiting our booth and DVD ran out very quickly. LinuxCon is mainly about presenting Fedora to other open source projects, people from all kind of companies that are interested in Linux, and also about networking. For example, a director from one of very well known IT company (I don’t want to name) came to our booth and asked how they can cooperate with Fedora because so far their development only targeted Ubuntu, but they don’t like the direction Ubuntu has recently taken and would like to stick with someone who stays in the Linux pack. We were also recruiting new contributors. Eilidh McAdam, a developer of Lanedo, showed her interest in contributing in Fedora and she is already in the process to become an ambassador. And hopefully, she’ll be a valuable packager or developer, too.

Apart from LinuxCon, I really enjoyed Edinburgh. Keiran took us to several nice places in evenings including a really good Indian restaurant. I was really surprised how cheap Scotland had become for us. When I was there 9 years ago, 1  GBP was 55 CZK, now it’s only 30 CZK, so everything is almost twice cheaper. And beer is still only around 2.5 GBP :) I was also surprised how many Czechs I met in Edinburgh. The receptionist in my hotel turned out to be Czech, so I checked in speaking Czech. The dealer at our roulette table at the LinuxCon party was also Czech. The weather was not that bad after all. The last day was even sunny.

I’d like to thank Fedora Project for sponsoring accommodation and dinner for booth staff and the Linux Foundation for providing us with a booth and tickets for booth staff which are otherwise very expensive.

Announcing Fedora Day at DevConf.cz

2 Comments

I’d like to publicly announce Fedora Day that will take place at Developer Conference 2014 in Brno, Czech Republic on February 9th 2014. DevConf.cz is the largest Red Hat developer event in the world. The 2013 edition was attended by 700 people, there were over 60 talks and 30 additional labs and workshops in two days. Because there has been high demand for a winter Fedora planning event, we decided to extend DevConf.cz into three days and make the third additional day a Fedora Day which should be devoted to Fedora hackfests and planning sessions. DevConf.cz is an ideal event for this because there have always been a lot over 100 Fedora contributors at DevConf.cz anyway.

There will be around 6 rooms (each for at least 20 ppl) available for us at the university on Sunday Feb 9th. I created a wiki page where you can add your session and hackfest. If you have an interesting topic for a talk, you may consider submitting it to DevConf.cz Call for Papers which is open until December 1st. Talks will be on the first two days.

A new website for the 2014 edition of DevConf.cz is yet to be finished. We’re working on that. When it’s done, you’ll find all necessary info about the conference there (transportation, accommodation, schedule,…).

DevConf.cz 2014 is held one week after the largest FLOSS event – FOSDEM. We picked this date on purpose, so that people from overseas can come for both events. Here is a planned schedule of events:

Feb 1-2: FOSDEM 2014 in Brussels
Feb 3-6: Internal Red Hat meetings in Brno office and hackfests co-hosted with DevConf.cz (e.g. systemd hackfest)
Feb 7-8: Conference days of DevConf.cz
Feb 9: Fedora Day

Looking forward to meeting you at DevConf.cz! ;-)

FAD Prague 2013

Leave a comment

We’ve decided to organize the very first Fedora Activity Day in the Czech Republic – FAD Prague 2013. It will be co-located with LinuxDays 2013. The goals are Czech- specific. We’d like to work on a small handbook we can print and give away to users who’d like to start with Fedora. It should cover basics such as what is Fedora, why to use it, where to get it, how to install it, how to work with the system etc. In spare time, we’d also like to work on improving and updating our online Czech Fedora user handbook which is wiki-based, but can be converted to a PDF. It’s already pretty long, over 250 pages. On the second day, we’d like to work on Czech translations. Not only translations of Fedora-specific software, but also translations of upstream software which is included in Fedora. Czech upstream translators are going to have a meetup at LinuxDays and this could definitely be common ground.

The whole event is meant to be for participants with different level of knowledge and experience. Newbies are especially welcome because the FAd is a great opportunity to start contributing to Fedora. There will be experienced Fedora contributors around who can help them and point them to the right directions.

What Desktop Environments Are Czech Fedora Users Using in 2013?

2 Comments

Last year, I published stats of what desktop environments Czech Fedora users are using. The data came from a survey which was done by the most popular Czech Linux magazine Root.cz. They did the survey again this year and made all the data available. By running queries on this data, you can actually do interesting statistics. But first the most important outcome of the survey: popularities of Linux distributions among Czech desktop users:

2013: Ubuntu 58.1%, Debian 26.8%, Fedora 16.9%, Mint 16.3%, Arch 10.1%, openSUSE 9.7%, Gentoo 6.9%, RHEL 3.8%, Mageia 2.5%, Slackware 2.3%, Mandriva 2.2%, Sabayon 1.4%, PCLinuxOS 0.8%, SLED 0.4%, others 7.1%

Last year (2012): Ubuntu 53%, Debian 17%, Fedora 12%, Mint 10%, Arch 9.5%, opensuse 9.5%, Gentoo 6.7%, Mandriva 1.8%,…

Source: root.cz

As you can see, Fedora remains the third most popular distribution after Ubuntu and Debian. The first four distributions have gained, but partly only optically because users could choose more distributions and apparently they were a bit more “promiscuous” than in the last year. For example, Ubuntu got 58.1% which is more than the last year, but it’s just 35% of the sum of all shares while it was 44% last year. DEB vs RPM is 101.2% vs 36.5% which is a better ratio than the last year’s: 80 vs 22.4%.

And now to the desktop stats. Popularity of desktop environments among Fedora users has always been a hot topic. We don’t really track what packages users are using, so no one really knows. The data from the survey surely don’t reflect the reality 100%. The survey was done among Czech users and doesn’t cover users “who don’t care” (like our moms, dads, grandparents who use Linux, but don’t read any Linux magazines or participate in surveys). On the other hand, users “who care” are interesting the most to us and 4745 users participated which is a large statistical sample. The stats from the last year can be found here. Unfortunately, they’re not very comparable with this year’s numbers because this year users could choose more than one desktop, last year they couldn’t.

fedora-desktops-2013The chart above shows popularities among all Fedora users including those who indicated that they were using other distributions, too. That’s why Unity has a significant share although it’s not even available for Fedora. It’s interesting to compare it with answers that come from users who use just Fedora, not any other distribution (die hards :-) ). They were approx. 1/3 of all Fedora users.

desktop-fedora-ubuntuLike last year, I compared it with Ubuntu numbers (also users who only use Ubuntu). As you can see, GNOME 3 stands out even more and achieve a number that is close to the share from the last year when users could only choose one desktop. KDE 4 is around 25%. Xfce has apparently gained some share among both broader and core Fedora user base. GNOME 2/MATE still has its user base, somewhere below 10% (similar to the last year’s numbers). LXDE has also gained a bit, but it’s apparently much more popular on Ubuntu than on Fedora. As you can see, Unity got completely filtered out which makes sense because if it’s not available for Fedora it can be hardly used by Fedora-only users. Cinnamon is also significantly more popular among users who use Fedora just as one of their distributions. Apparently, who wants Cinnamon, goes for Linux Mint because it doesn’t have a large share among Ubuntu users as well (BTW it has a 59% share among Mint-only users).

I will bring some more stats when I find time again. For example how Fedora market share changes with the age of users or their experience.
