FOSDEM 2012

This year’s FOSDEM is over and I hope that most of us have by now recovered from an exhausting weekend that was first and foremost exciting and a lot of fun! With about 12 people, the Xfce group was—I think—larger than ever before. Add to that a fairly large number of my colleagues from Codethink, into which I bumped at the beer event and FOSDEM itself from time to time. Despite mostly staying with Xfce, I enjoyed knowing and meeting people all over the place.

Unfortunately, some of us—myself included—missed half of the beer event because our trains and planes arrived late. Snow in Brussels, a cold weekend ahead. When we arrived at the Delirium Café at around midnight, I was glad to see that all the others had already made friends again. Olivier, Stephan, Peter, Nick, Simon, Christoph, everyone was there, some of them sufficiently drunk, I imagine. Although to be be fair, you wouldn’t really notice. Most of us left not to long after that in order to be in a good condition in the morning. Having only caught up half on drinking, Christian, Mike and I ended up staying at the Delirium with a few Codethink colleagues including Sam, Luc and Javier—until they finally kicked us out at around four in the morning.

Food, taxi, 2 1/2 hours of sleep later and we were sitting in the hotel, enjoying a fantastic buffet breakfast. Admittedly, I couldn’t eat that morning, ending the night in the Delirium had lead to quite a strong hangover. After the majority of us had gathered in the hotel lobby, we squeezed ourselves into the 71 bus in two groups and finally arrived at FOSDEM. I do not remember the details of the day, but it was a great mix of talks (including my own one about Tumbler, which I felt was not very special, picture below), chatting and minor hacking (at least on my side; Nick made good progress with the settings editor in the meantime). During the day, Jean-Francois, Jens and Mark joined us and we (or most of us at least) ended the day having food in a Vietnamese restaurant close to the hotel and a beer in the hotel lobby.

Sunday was similar, except that I could finally enjoy the breakfast. Lovely. Unfortunately, we didn’t manage to get everyone together anymore, so our initially large group was now split up into smaller ones for the rest of Sunday. We still managed to have a few technical chats about Xfce that day and made a few decisions (see below). Regards talks, I mostly remember the Wayland Q&A session and a talk about social engineering in free software communities, Most of us left in the afternoon or evening. I met up with Luc, Sam, Javier and a bunch of other people to have food in a very nice restaurant. Got up at six in the morning, walked to the central station, took a plane home from the airport and went back to work in the afternoon. Unlike a few others I seem to have escaped the typical illnesses (cold, broken sleep cycles, general exhaustion) that events like FOSDEM always bring along.

Xfce-Related News — Fresh from FOSDEM

Wayland was big this year. I will spare you the details of how it works. Throughout the weekend, we had various discussions that involved Wayland. While it may take some load of Olivier by eventually making window managers obsolete, there is still a major problem with it: it does not support the XEmbed protocol, and therefor will break pluggable settings dialogs and panel plugins. We have sent mails to the wayland-devel list to find out how they feel about this. For now, I suppose this is all we can do.

Reorganization of the settings dialogs

One thing we decided on Sunday was to reorganize the settings dialogs so that the location of particular types of settings becomes more predictable. This applies to appearance and window manager themeing, and the application keyboard shortcuts and window manager keyboard shortcuts in particular. We will rearrange some of these tabs and merge them so that all related settings are in one place. We will also merge the window manager and window manager tweaks dialogs into one.

Release Schedule for Xfce 4.10

Despite a lack of completed features in Thunar (which are unlikely to get finished before 4.10), there are only a few things that really keep us from releasing Xfce 4.10. We have not decided on a release date, but if things go well, we should be able to roll the first pre-release one month from now, in early March. This would mean that a final release in May or June would be feasible.

Possibility of a hackfest

Meeting up with the team is always great fun. Unfortunately, FOSDEM is a busy event and only lasts two days. Like last year, we discussed the possibility of an Xfce hackfest in the future. I would love to see this idea becoming reality. If half a dozen of the relevant people can make it for at least a couple of days, this could greatly benefit the development of Xfce. Ideally, such a hackfest would span over at least 4-5 days, ideally including a weekend to make it easier to attend for people with jobs. Given a relatively small group, it might even be possible to hold an event like this at someone’s flat. This is definitely something that we will look into soon.

Like every year, FOSDEM 2012 was a great event. And like every year, a few more nicknames have turned into real faces that, unsurprisingly, belong to incredibly friendly human beings! I only wish that we had more time to discuss things face to face and do some serious work on Xfce together. In any case, this calls for another iteration next year. And with that, I shall end this wrap-up.

Xfce Foundation launched at FOSDEM!

This year’s FOSDEM was a special one. Read more about it in this mail:

Hi everyone,

as some of you might have read, several of us Xfce developers and
packagers have attended FOSDEM this weekend. There was a lot of talking
and a bit of brainstorming of course. Together we enjoyed food, beer,
talks and also did something that we have been struggling with for
several years now: we launched a non-profit organization for Xfce.

Yes, you read correctly: the

  Xfce Foundation

was founded by a group of us on Saturday afternoon! It still needs to
be registered, so technically it's not an "e.V." (a non-profit
organization registered in Germany) yet. But it will be, we are working
on that.

The eight founding members are:

  #1  Christoph Wickert
  #2  Landry Breuil
  #3  Jens Luedicke
  #4  Christian Dywan
  #5  Nick Schermer
  #6  Jérôme Guelfucci
  #7  Jannis Pohlmann
  #8  Lionel Le Folgoc

Please give everyone a hug or at least a thumbs up next time they pop
up on IRC. Without them being there this would not have been possible!

The main part next to signing the articles of association (which we
will soon upload somewhere, probably on foundation.xfce.org or
something like that) was to elect the initial Board of Directors of the
Xfce Foundation. Without objections the following people were elected
to the Board of Directors with a 2 years mandate:

  President:
    Jannis Pohlmann

  Vice President:
    Nick Schermer

  Vice President and Treasurer:
    Jérôme Guelfucci

The Board will now take care of the registration process and will meet
up for the first time on March 1st, 2011. There will be a general
assembly for all Xfce Foundation members on March 6th, 2011.

We will soon announce more details about the decisions that were made
and about how you can become an Xfce Foundation member (it's really not
difficult and it won't cost you any money -- but there are obligations
connected to it of course).

After the registration we will create a bank account and a new paypal
account as well in order to collect donations. These donations will be
tax deductible!

Stay tuned for updates on this. I hope you are as excited as we are
about this. I hope it will help a lot in pushing Xfce forward.

Cheers,
Jannis

Proud Founding Members

Attending FOSDEM 2011

I'm going to FOSDEM, the Free and Open
Source Software Developers' European Meeting

Today Nick and I booked hotel rooms for FOSDEM so now it’s official that the two of us will be there. I’m very much looking forward to it and I’m hoping to meet some of you at the FOSDEM Beer Event on Friday! Still need to think about a way to make ourselves recognizable as Xfce folks though.

If you are planning to attend and would like to meet any of the Xfce folks, please add your name in the wiki:

  http://wiki.xfce.org/events/2011/fosdem

We haven’t decided where and when to meet on Saturday and Sunday but I’m sure we will find something. Stay tuned for additional announcements on this weblog.

In addition to celebrating the 4.8 release of Xfce which is scheduled for next weekend, one of our goals for FOSDEM 2011 will be to sign the papers for registering the Xfce Foundation e.V. in Germany. The details of this still need to be worked out, however. I’ll keep you posted about this as well.

If you would like to talk to me about things other than Xfce, please drop me a mail and I’m sure we can arrange something.

Xfce at FOSDEM 2009

FOSDEM is over and it was a blast! Finally, after about four years, the team met again. It was the first time for me and it was great to meet them all in person. Olivier, Yves-Alexis, Nick and I stayed at the same hotel. Stephan stayed in Gent and the others spread over several other hotels in Brussels.

Friday

I arrived early on Friday and relaxed in the hotel room for a while, going through my slides and listening to a couple having sex next door for hours. If you’re able to count the orgasms then it’s definitely too loud. So I left the hotel and walked around in the inner city of Brussels for a while until Yves-Alexis, and shortly after that, Nick and Stephan arrived. We had a few beers at a bar around the corner and later went to for Pasta and Pizza in an Italian restaurant close to the hotel where Jens joined us. After that we went to the FOSDEM beer event and stayed there until half past midnight, only interrupted by the arrival of Olivier whom we had to take to the hotel. The beer was nice and since the place was so crowded we had a hard time understanding each other … but we somehow managed it.

Saturday

We got up at around 7am the next morning and of course the beer from the evening before didn’t really make things better. The nice thing about the hotel (Hotel Du Congres by the way) was that there was free breakfast included though. It was rather basic but it did it’s job. Shortly after that we left for FOSDEM. We arrived in time for the keynotes and met Jean-François and Maximilian on our way to Janson (the large auditorium). Later we went for some french fries and mainly spent our time in the X.org devroom. Some of us went to the LXDE lightning talk and were quite amused by their claim that LXDE is better than Xfce (which is denied by the guys at LXDE, so they might not actually have said that … what does better mean anyway?) and the huge number of slides showing photos of their team at different conferences. Later that day we went to a restaurant called Big Mama in the very heart of Brussels were we had a beer and nice food. Everyone went to bed afterwards, except Nick, who kept hacking on the panel.

Sunday

Sunday was a big day for me - I had a talk about Xfce 4.6 and the future of Xfce scheduled at 11am. I didn’t really sleep well and was nervous the entire morning. It didn’t get any better when I had finally booted up my laptop and the microphone was turned on. I don’t know how long I talked but I have the feeling that I literally speed-talked through the slides. I forgot a few things I would’ve loved to mention but all in all I think it was ok. There were quite a few sceptical faces in the audience but also a few who looked very pleased by the features and plans I presented them. I definitely think it was ok for my first talk in English at a big conference but I know I can do better. So I’d be absolutely happy to do that again next year!

I felt very relieved afterwards. We then went out to take a few group pictures (the following one was shot by Jens). In the meantime, Samuel and Jelle de Jong had joined us (I have no idea where Jelle went afterwards, but Samuel stayed with us for the rest of the day).

After that we want back to one of the devrooms until Maximilian came back from his car with a number of sandwiches he had bought on the way. We had a beer at the FOSDEM bar, ate our sandwiches and then went back to the cross desktop room for Stephan’s talk about Xfce as a platform. I think he did a good job overall, especially considering that he had just finished his slides the night before. I would’ve loved to see more about how to use the different libraries and maybe more details about our plugin APIs but he covered a few very important things about Xfconf.

After that we had another beer at the bar and went to the last talks in Janson. Samuel dropped his full beer, I accidently kicked my empty one and Olivier and I left early for the FOSDEM bus back to Brussels-South. I managed to catch an earlier train to the airport, had a short flight, then had to wait for the bus from Hamburg to Lübeck for 90 minutes and finally arrived at around half past midnight.

I think it was a lot of fun and I’ll definitely go to FOSDEM again. It was nice to put a face to all the names of people I’ve been working with over the last few years. Thanks to everyone I met there, it was a real pleasure! Hope to see you all again! Thanks to all the people who went to our talks (oh, and to that guy who wanted that picture of him and me - could you send it to me please?) and asked questions (“Has the Xfce team ever thought about participating in Google SoC?”, “How good is the relationship of Xfce with Xubuntu?”, “Are you still aiming to be lightweight?” amongst others). It was also great to see several packagers, like Mark from Foresight, Landry from OpenBSD and Christoph from Fedora.

As I’ve mentioned before, I would really like to talk at conferences again. It’s a challenge but definitely a nice one. If you know any that could be interesting for Xfce, please let me know!

Oh, and by the way, if you’ve taken any pictures of us at FOSDEM, please let us know!
