Ubuntu Developer Week happens on IRC next week. I'll be giving my introduction to PyKDE with a WebKit web browser tutorial. There's plenty more interesting talks, see you there.

It's Friday now and hackweek comes to an end for me. It was exceptionally fun and we got some decent work done. The team was fabulous, a combination of SUSE and external community guys. Frank was here for the whole week and worked on the API and the opendesktop.org implementation of it. Sebastian joined us for two days and we had a lot of interesting and useful discussion how to put Nepomuk into the picture, Dirk started to write a Plasmoid for showing the activity log on the desktop, and Zack was here this morning giving us moral support and inspiration. We didn't completely realize the "Social Desktop" yet, but we laid some groundwork. The most visible result currently is this screenshot: Read More

Many of us have the cool Nokia N810 that is an ARM system based on maemo. To compile software for it, you will normally use scratchbox. What a pitty scratchbox only runs on 32bit hardware. As a proud user of a 64bit desktop, I have to use a virtual machine for running scratchbox. Now the question is what is the better virtualization solution: VirtualBox or VMWare? Read More

Tomorrow it starts! The (at least for four of us) long awaited KPhotoAlbum development sprint! Tuomas Suutari, Jan Kundrát, Henner Zeller, and I will all by together at my place in Hjørring, Denmark the coming week to bring the development of KPhotoAlbum forward. Read More

While browsing through kde-look.org I found a cool idea for visualizing a daily agenda. This reminds me of the Akonadi architecture diagram and I even have code (probably not up to date) for drawing this kind of diagrams. So I guess it would be doable without too much effort to implement a daily agenda viewer like this. Would be a fun project. Read More

A while back I blogged about querying dbpedia with sparql. The queries in that blog were pretty simple. Today, I present a more complicated example. SELECT ?a, ?long, ?lat WHERE { http://dbpedia.org/resource/Borne%2C_Overijssel http://www.w3.org/2003/01/geo/wgs84_pos#long ?centerlong ; http://www.w3.org/2003/01/geo/wgs84_pos#lat ?centerlat . ?a http://www.w3.org/2003/01/geo/wgs84_pos#long ?long ; http://www.w3.org/2003/01/geo/wgs84_pos#lat ?lat . FILTER ( -(?long - ?centerlong)(?long - ?centerlong) - (?lat - ?centerlat)(?lat - ?centerlat) > -0.01 ) } This query gives you all items in the english Wikipedia near where I live. Read More

My previous post touched on the horrid FPS you can expect from any graphics intensive Qt app on the N810 at the moment. Ariya has pointed out one reason for the bad numbers: Qt decides to convert all 16 bit pixmaps to 32 bit before blitting even if the source QPaintDevice and the destination QPaintDevice are both 16 bit.

This week is hackweek at SUSE and people are frantically hacking on all kind of stuff. Fun. My project is the Social Desktop, which is the buzzwordy title for an implementation of the Open Collaboration Services API (see specification on freedesktop.org). Frank Karlitschek has joined the fun and is at the SUSE offices for hackweek, so server and client implementations go hand in hand. The idea is to bring the community to the desktop and take benefit of the fact that free software projects are not only about software but also about community. This can provide a lot of extra value for our users, especially as the desktop is the place where all the social web data from different sites comes together and the user is in full control of what happens to the data and how it is combined. For some more background have a look at Frank's Akademy keynote. Read More

When thinking about how to implement a client for the Open Collaboration Services API which Frank presented at this year's Akademy keynote I came across the question of how to generally access a REST web service on a client. Read More

Back from FrOSCon. I followed the frog grasshopper. It was great to meet so many nice people again :) The KDE table (booth just doesn't fit) was shared with Kubuntu and Amarok. I think we all fitted together nicely, not really appearing as three projects that much. Thanks to the Kubuntu people for helping a lot in keeping the table/booth running! The blue table cloth we had (kudos Kubuntu) gave us extra appeal. And if it hadn't had a little too much beer in the evening that would have included Sunday... Apart from talking to visitors and other projects and listening to talks, Saturday evening was all about being social. Or it was all about beer, I don't remember clearly. I think we did fairly well on the dance floor also, I enjoyed bouncing around with Sebas, Danimo, Markey, Sven and all the others, though I do hope, no photos of us dancing around professionally are around ;) Thanks a lot to Valerie and Jörg for giving me a ride, that was awesome. And the Grasshopper. Read More
