SUSE hack week

Hack week. One week of ferocious hacking on new ideas without interruptions. SUSE does this twice a year to trigger those innovations, you can't realize when you are swamped by day-to-day work. Of course it's not the only way or opportunity to do new things, but it gives the freedom to actually get something done on a topic, which is not covered by conventional product planning. It's productive, it's fun, it creates great results. Next week it's the seventh edition of hack week. We are collecting ideas and activities in openFATE.

Nat started the first SUSE hack week four years ago. Others followed suit. This is quite a bit of history. So I was thinking of what I did the six times before, and what I want to do at the seventh time. Here is a summary. My hack week blog, which I usually use to report about my hack week progress, has some more details.

Hack week 1: Dynamic web services portal

In the first hack week I tried to put a dynamic web services portal together based on enriched ("activated") Atom feeds. The goal was to collect information from various source like Bugzilla, Email, FATE, Blogs, aggregate them and offer actions to work on them, such as closing a bug, responding to an email, but all from one uniform view. I wasn't able to really get this project off the ground, as I was spending quite some time on helping others, watching, what was going on, and discussing ideas. A week probably also was too short for the ambition of this project. But it was an interesting attempt, and failure is an option at hack week. Others were more successful. Ars technica has a nice piece "Novell Hack Week: an experiment in innovation" with lots more details.

Hack week 2: KDE 4.0 beta

In the second hack week a couple of KDE hackers at SUSE teamed up to bring some parts of KDE 4.0 into shape for the beta release. We took a big office sat down together and worked on various parts of KDE to make it ready for the next beta release. I did a dive again into the KOrganizer code, fixed some bugs, cleaned up the code, did some porting work, and more. It was a very targeted effort, and it was great to work in a team.

Hack week 3: Social desktop

The social desktop project was one of my most successful hack week projects so far. Again it was a team effort. Frank Karlitschek, Sebastian Trüg and Dirk Müller joined me to work on the implementation of some of the social desktop ideas Frank had presented at his Akademy 2008 keynote. While Frank was working on the server side I was implementing libattica as client library to provide social desktop features via the open collaboration services protocol. We got quite a bit of work done, and the project won a 3rd prize as best overall project at hack week. There is an interview, which was taken at Hackweek III, where I give some background and also talk about some other stuff around my work.

It's great to see that the project is still alive and kicking today, several years later. The protocol and the client library I started are widely used now, and it's used as base for  many different use cases, such as downloading wallpapers, providing a software shop, or updating Plasmoid backends. It's awesome when ideas pan out.

Hack week 4: KDE SDK

For hackweek 4 I thought I would try a big, ambitious project, I wanted to do for a long time already, provide an integrated, easy-to-use kit for KDE development. Taking great components like Qt Creator, using wonderful tool like the build service and SUSE Studio, I wanted to put together a software appliance, which could easily be used to develop KDE programs out of the box without much setup effort. I wrote a Qt Creator plugin, added KDE templates, did some services integration with git and opendesktop.org, and put everything together in an appliance. I got a lot of good feedback on the concept, but it was more work than I could do in a week, and I wasn't able to follow up later, so it's still an unfinished project. Would be great to eventually take it up again.

Hack week 5: SUSE Studio GUI client

SUSE Studio has a nice API, which can be used to control all the various aspects of appliance building and publishing. For the fifth hack week I decided to implement a GUI client for SUSE Studio using this API. It also gave me the opportunity to hack a bit on kxml_compiler, which is part of Kode, my multi-year side project for handling various aspects of XML in C++ in an easy way. I made quite some progress and had a client able to run test drives with native integration in the UI. I didn't find time to continue to work on this project after hack week, though, and there are other clients now as well. I'm not sure how much future this project has.

Hack week 6: Polka, the humane address book for the cloud

This was my most ambitious hack week project so far. I fundamentally rethought how I approached address book applications, and came up with a concept based on user's view on people from ground up. I called it a humane address book for the cloud. I had thought about that quite some time already, and also had written some code. But hack week gave me the opportunity to really bring it to a state, where I could share it with others. The feedback was amazing. One of my favorite responses was "I saw the future". Polka now is in a state, where it's actually useful, and I did a first release during the last openSUSE conference. This project has a bright future, I'll definitely continue to work on it.

Next hackweek: Qt library archive

This is my plan for hack week 7. Get the Qt library archive project beyond the prototype state. This started at a KDE sprint in Randa, was continued at the Qt Collaborator's Summit, got some more discussions at the Desktop Summit, and now needs some work to be taken to the next level. The idea is simple, create a web site listing all Qt libraries out there, and an easy way how to use them, think CPAN for Qt libraries.

There are a lot of things, which need to be done. If you are interested in joining me to work on this, don't hesitate to ping me. These are the things I plan to work on:

• Finalize library meta data format
• Adapt prototype tool to support the final format
• Collect real meta data for as many libraries as possible
• Finish the backend for installing binary packages on openSUSE via the openSUSE build service
• Look into backends for other distributions, ideally using the same build service integration
• Get libraries packages, which aren't
• Implement a Qt based client, possibly with a QML based GUI

A lot to do. Help is very much appreciated. If you are at SUSE or somewhere else, if you are a KDE, Qt hacker, a packager, an upstream library author, a Ruby programmer, or a QML specialist, don't hesitate, you are very welcome to join the fun. Just contact me, and we'll figure out the rest.

My openSUSE conference

Last week was the openSUSE conference in Nürnberg. Here are some of my impressions. I loved the relaxed, crazy atmosphere, mixing so many different people with so many different backgrounds, skills, interests, and fascinating projects. This spans quite a broad range of topics, not only on the software side from kernel to office suite, but also in other areas from cheese over quadrocopters to self-replicating machines. This community is seriously rocking the boat.

I gave two presentations at the conference. The first was about Polka, my humane address book for the cloud, which I mostly wrote during the last SUSE hack week. I explained the concept of addressing the problem from the user's side, not from an implementation point of view. Humans don't think about people in terms of vCards, but in terms of groups, pictures, time, and space. The Polka user interface reflects that.

I also did the first release of Polka during my presentation live on stage. So if you want to try it, go to the Polka home page and download the tarball. It's an early release, but it should work quite well. I intend to stabilize it a bit more and then do a 1.0 release. If you find bugs, please let me know.

The other talk I gave was a lightning talk in the Speedy Geeko session. Twenty slides in five minutes. This was fun. There were a nice variety of topics, including bees, fire fighters, and crazy scotsmen. My talk was about Maria Montessori, the Italian educator, who founded the Montessori schools. A lot of the concepts from her philosophy of education have interesting parallels in what we do in open source development.

There were many more talks. I only had a chance to listen to a few of them, but I enjoyed Greg's talk about the Kernel and Tumbleweed (change faster to be more successful), and Martin's talk about Wayland (wait until it's done, and then wait some more). Dominik showed the latest from SUSE Studio in a presentation and we also had the kiosk at the venue, which always is a great way to show, explore, and explain Studio.

Another great thing was that there were so many KDE people at the conference. It shows the strong relationship of openSUSE and its upstream projects, and KDE makes some excellent use of openSUSE, e.g. as base for Plasma Active. This is a great fit, and I think it's hard to underestimate how important collaboration between downstream and upstream is. We'll only win together.

Finally it was great to feel the enthusiasm of the community, people who came from all over the world, hang out at the barbecue in the evening, listen to 8-bit music, drinking openSUSE beer and chatting about openSUSE and many other things. The Zentrifuge was a wonderful venue for that. It certainly was an inspiring event. When is the next conference?

Back from Berlin

I'm back from the desktop summit, back from Berlin. It was an intense event, lots of great people, lots of great content. So I arrived at home tired, but inspired. Read on for my personal conclusion.

The conference was excellent. All the presentations I saw were of high quality. It also turned out to be exactly the right thing to put everything into one program, independent of affiliation of speakers or targeted community. I enjoyed the opportunity to learn more about some projects I'm usually not following that much. It was also great to have presentations done jointly by people from different communities, like the one from Lydia and Seif, or the upstream/downstream discussion led by Vincent, or the intern show case lightning talks.

One of the highlights of the conference was the panel discussion about copyright assignment. It's a complex topic, but the panelists brought up good arguments and lot of food for thought. Mark spoiled his argumentation a bit at the end by introducing his generosity concept. This certainly has its place when talking about motivation in a community, but in the context of legal agreements with companies it's very questionable, if generosity should be a dominant concept. My takeaway from the panel and some other discussions I had at the summit is that KDE e.V. is in a very good position here with the Fiduciary License Agreement, we optionally provide for KDE contributors. This provides a good balance of the different interests and adds safety for contributors and community.

The other big thing at the desktop summit was the general assembly of KDE e.V. It was a very focused and organized session. Mirko led it in record time. Lydia was elected as new board member replacing Adriaan, and I was reelected for my third term. In the afternoon we had a good BoF session about KDE e.V. questions, and we had a very good discussion about how to involve more people in KDE e.V. work. There is a lot to do, which is very important to be able to sustain the support for the community, expanding the individual supporting membership program, managing relations to existing and new corporate partners, maintaining our trademarks, keeping up and improving our infrastructure for sprints, membership, and KDE e.V. work, the next Akademy, and much more. We will do a KDE e.V. sprint later this year to get some work done on these topics, and to involve more people beyond the members of the board.

The last part of the desktop summit was the workshop week. It was packed. It felt more busy to me than at any previous event. There was a lot going on. The experiment with showing all KDE sprints of the last year in one hour worked well. We had 21 lightning talks and it was impressive to see, what happened there, how many people spend their passion and skills on these focused events. It can't be underestimated how much energy they put into the community, and how much things get done or triggered when you put a bunch of KDE people in the same room for a long weekend. For next year, I'll try to put this kind of session into the main conference program, as it really deserves to be shown to a big audience.

Another nice trend from the sprints became more visible. Several people used Kanban as a method to organize, visualize, and track the work done at sprints. Kevin introduced it a while ago, and the feedback to that is very positive. It's a low tech method of managing the activities at a sprint by basically putting sticky notes on a wall. By providing some simple rules for the flow of these sticky notes through the different stages of work being done, and applying constraints to how much work is going on in parallel, it's possible to maintain some good flow. Things get done quicker and it's easier to adapt to new things coming up. I think Kanban works best for the longer sprints, where you have more than just two short days on a weekend, but it's certainly worth experimenting with it as it's designed to adapt to different needs by modifying the rules and constraints as needed.

Finally I noticed two trends, which I really welcome. First is that there seems to be a growing interest in usability and design. We had design keynotes. It was said in many talks that people were looking for more involvement with designers. Technologies like QML provide new ways to involve designers and design thinking. There were usability BoFs and lots of discussion about how to better address users's needs. The second trend is that there seems to actually emerge a convincing story for KDE on devices beyond the desktop. Plasma Active is spearheading this, and many people are able to contribute there now with the ExoPCs Intel gave out for development. It could be called a mobile story, but it's more than that, because many of the concepts work on desktops as well, so it's rather about addressing the spectrum of devices we are talking about for quite a while now. This goes well with the first trend about focusing more on design, as we are exploring areas, where there don't exist many strict concepts about how to do things, and it could be seen as closer to the user as some of the other areas we are active in. Lot's of interesting stuff is happening here. I'm looking forward to what we will be able to come up with in the next future.

Last but not least I was really impressed by the work of the volunteer team. They did an amazing job in making the event run very smoothly. This, together with a great venue and the support of the university, the city, and all the sponsors, provided the perfect environment for the community to have a productive and enjoyable time. The volunteer team also showed how much we can reach, when KDE and GNOME people are working together. It sets a high bar for future events. Thanks a lot to everybody involved.

One year of KDE sprints

On Wednesday we'll do the experiment to present all KDE sprints which happened within the last year in one hour. We have speakers lined up, slides prepared, and just need you to come and listen. The session is happening on Wednesday, August 10th, at 10am in room 1.205 here at the desktop summit. See the workshop program for more details.

We had such a great set of no less than 21 sprints over the last year. So it will be exciting and fun to see a compressed version of that in one go. I'm looking forward to see you at the session on Wednesday.

Approaching the desktop summit

It's only one day left until the global KDE and GNOME communities meet at Berlin for the second desktop summit. Hundreds of free software contributors from all over the world, the core of the free desktop community is meeting at the Humboldt-Universität zu Berlin in the middle of the German capital from August 6th to 12th.

It's those people who create the software, which millions and millions of users see, feel, and use every day, on the desktop and beyond, who make great technology accessible to everybody. Many of you participate in this effort, and by doing this with free software we are providing nothing less than one of the building blocks of free society. Getting all the creative minds, the people with passion for beautiful, elegant, powerful, amazing software, together at one event, that's remarkable, and I'm looking forward to what we'll breed at Berlin, what ideas, collaborations, what code will emerge.

For me one of the most important parts of the desktop summit will be the general assembly of KDE e.V. Without KDE e.V. events like this wouldn't be possible. It provides the organizational foundation, which is necessary to run a community on the scale KDE has reached. The general assembly is the annual check point, where we report and reflect on the state of the organization, and decide about its future direction. As a member of the board it's my duty and my honor to report on what we have achieved.

This year is a bit special as we'll have elections for two of the five board positions, and I'm running for my third term. While we have achieved a lot with KDE e.V. over the past years, we are still in a position, where we have the chance to achieve a lot more, for the KDE community, for free software, and, as already said, for a free society in general. To make some of this happen is one of the main goals I have for my third term. I need your support and your help for that, and I hope we can build an even stronger organization, where many of you join the effort of making the world a better place through our technology.

The main part of the desktop summit of course is the conference. We have a great lineup of keynote speakers: Thomas Thwaite, Claire Rowloand, Dirk Hohndel, Stuart Javis, and Nick Richards.We have dozens of other presentations, which cover the whole spectrum of the free desktop, technology, community, from both, the KDE and GNOME communities, and related project. If you are interested in free software on the desktop and reaching beyond the desktop, there is no better place to be than Berlin next week. As a special highlight we have a panel about copyright assignment with Mark Shuttleworth, Michael Meeks, and Bradley Kuhn, moderated by Karen Sandler. This is going to be interesting. KDE has a clear position there with the fiduciary license agreement we created with the help of the FSFE, which preserves freedom, gives equal rights to contributors, and doesn't create any barrier of entry.

The other big part of the desktop summit will be the workshops and BoF sessions, the less formal events, which take place towards end of the week. This is where people have time and opportunity to mingle, to collaborate, to exchange ideas, to discuss projects. I'm running an experiment there, the attempt to cover a full year of KDE sprints in one hour. We'll have a series of lightning talks giving an impression of what happened at the 21 sprints we had since Akademy a year ago. I'm also looking forward to discuss and finalize the recommended KDE git workflow we came up with at the sprint in Randa in June. Finally I also intend to move forward with the idea of a Qt library archive, which also originated at Randa, and which we discussed in more detail at the Qt contributors' summit.

As always I'm also carrying the hat of my employer, SUSE. openSUSE is a great distribution to run both KDE and GNOME, and SUSE Studio, my main project at SUSE, also can be useful in the context of the desktop communities in various ways. If you are interested in any of that, would like to discuss it, or need help getting something done, don't hesitate to talk to me.

Tomorrow I'll board a train and go to Berlin to dive into this special sphere of the free software community again. It's my ninth of the big annual events organized by KDE, be it Kastle, Akademy, or the Desktop Summit. I can't wait to meet all the old and new friends who make up this wonderful community.

See you in Berlin.

KDE 4.7 release party in Nürnberg

Following the motto "Think Global, Party Local", we'll have a KDE 4.7 release party in Nürnberg on Wednesday, 27th July. It will take place at the SUSE offices, starting at 19:30, and we'll have a few short talks, and the opportunity to chat, have some beers, and celebrate the latest KDE release. If you happen to be in Nürnberg and would like to meet some of the local KDE guys, you are very welcome to join. See the community wiki for the details.

Putting things together

Half a year ago there was a thread on the kde-core-devel mailing list with the topic "why kdelibs?". I gave a potential answer and this resulted in a series of great discussions. While these discussions were very constructive, it was pretty clear, that we would need an in-person meeting to finally answer the question about the future of the KDE platform.

At the same time Mario was preparing the third KDE developer meeting at Randa, Switzerland. It began with a Tokamak sprint in 2009, continued with a combined KDE multimedia and KDE edu sprint, and for 2011 he was preparing a triple sprint with KDE multimedia, KDevelop, and Nepomuk. Mario put up with the adventure and offered to host another sprint as well, so we put things together and added the Platform 11 sprint to the list.

The sprint ended two weeks ago. It turned out to be four and a half sprint in one, with the kdenlive gang joining us for some extended hacking fun. Almost sixty KDE people were in the middle of the Swiss mountains, coding, discussing, and plotting the future. It was an inspiring and productive event, thanks to the hospitality of Mario and his team (including his family), thanks to the incredible energy, which is unleashed, when KDE people get together. I have been at many sprints over the last years, but it still amazes me every single time, that it immediately feels like meeting old friends, even if you have never met the people in person before. But it's more than just a bunch of friends. It's a group of professionals, putting an incredible amount of passion, creativity, and talent into KDE. This makes these kind of events unique and it's stunning what can be achieved there.

For me the most important result of the Platform 11 sprint was the consensus we built about where we want to move the KDE platform. It's about making the components we provide more accessible to developers, expanding our reach, and cleaning up our technology. We'll go with more modular frameworks with less dependencies, which can be used naturally along other Qt libraries, and a release process which will deliver our work quickly. More details are described in a series of mails about the future of our frameworks from Sebas, the intended organization of our frameworks from Kevin, a plan to transition to KDE frameworks from David, and the KDE git workflow from me, on the kde-core-devel mailing list. To reflect the changes we'll refer to the KDE libraries and required runtime components as the KDE Frameworks in the future and retire the use of the platform term. This expresses well, that KDE provides utility for building great applications, but isn't tying users or developers to a monolithic block of dependencies.

What happened to the idea of merging the KDE development platform and Qt? It was a radical idea to trigger some thoughts, not a plan how to actually proceed. The main goals behind the idea, to make the KDE libraries more accessible, lower the barrier for developers using the libraries, to remove redundancies, to clean up the developer story, grow the developer community, and provide a consistent story to users, they still hold. A lot of what we discussed at Randa goes into this direction. Libraries will become more self-contained and we'll try to put quite some code into Qt. For a full merge neither Qt nor KDE are ready yet, so I think it's a good solution for now, to work on the concrete plans we came up with at Randa along the goals of making the KDE frameworks more easily accessible and available to a wide audience of application developers.

The other sprints happening at Randa also created impressive results. The multimedia guys were putting together the bits and pieces around Amarok, Phonon, PulseAudio, and KMix, and kdeenlive joined the KDE community. At the Nepomuk sprint the Zeitgeist and Nepomuk developers came up with a plan how to integrate their technologies, putting together the best parts of semantic technology on the free desktop. The KDevelop group was tremendously focused, they weren't really visible to me. When I was leaving Randa I met Alexander Dymo at the train station, as we took the same train, and he told me that they managed to check off all their todo items during the sprint. That's impressive, and it reflects the spirit of the Randa meeting.

We had a great mix of people at Randa, KDE dinosaurs and fresh blood, people central to the community for years, and people just joining. We had some friends from the GNOME community there, and we had local people being interested in what we were up to. Even when taking a walk through a bit of the mountains around Randa, we met people interested in what we were doing and ended up discussing KDE.

In the end to me the dominant theme of the meeting was putting things together. We did that with our plans for the KDE frameworks, we did that with various parts of the community, we did it with our relation to other communities, and of course we put quite some code together on top of all that.
