KDE Blogs 

This summer was a good summer for syncing. A couple of days ago the OpenSync project released their version 0.19 which now finally is able to sync the KDE desktop data also when using the KDE frontend KitchenSync. Previously this wasn't possible because the event loops of the KDE plugin and the frontend got in conflict, when running in the same process. With a new architecture which allows to run plugins in separate processes communicating with the sync engine via an IPC protocol, OpenSync solves this problem. This work was started at the OpenSync meeting in Amsterdam earlier this year and now finally completed and released. Congratulations! Read More

Near the end of Akademy, when it was finally short enough on talks, BoFs and whatnots to leave some time for serious hacking, after staring at the source of glcompmgr, I finally decided that this OpenGL compositing thingie cannot be that hard. And, 24 hours (with some sleep in the middle :) ) later, after staring at the glcompmgr code more, using code from it and searching in the OpenGL Redbook, I had this: Read More

.. but this scripting thread that keeps going and going on kde-core-devel is pathetic. Bah! Currently I am no longer reading the thread and simply deleting every email with scripting in the subject. He who codes decides and as soon as an application is working properly in any scripting language (therefore the bindings are working fine) it should be shipped inside a module. Period. If it creates an extra dependency then so be it. I assume cmake will be made smart enough to make sure that when the bindings are not there the application will not be built and cmake will not bail out with a "requires these and these bindings" error. If you feel that you have to have the same app in C++ then code it yourself. Again he who codes decides. You need it in C++ and you make it better than the scripting version, fine we ship both versions as long as they are properly maintained. That goes for any software we put inside the modules like it has always been done. Read More

This week I've been converting the QtDBus examples from Qt 4.2 to Ruby, and getting the various Qt::DBus* classes working. Now QDBus support is pretty much complete and it will be fun hacking up some interesting apps like bridges to web services like I tried with DCOP. I'll have to get kde4 kdelibs and whatever else builds so I've got some sample apps with DBus support to experiment with. Read More

Like many I came home from aKademy with a little flu thingy and I fell asleep the moment I got home last sunday night. I slept a lot this week trying to get rid of this bug but also just because I really was low on sleep anyway so I had to replenish :) So next to sleeping and talking on IRC (hi Kat!) I didn't do a whole lot this week. Nobody again say you don't need a holiday if you don't have a steady dayjob! Read More

So I was finally forced to switch to KDE4 (again, but this time for real, apparently ;) ) to start porting my Krita 1.6 stuff to Krita 2. Meaning I now have some new and not completely unrelated things to talk about. Read More

My last last blog entry about Marble covered how Marble is meant to be a generic geographical map widget. It shows the earth as a sphere but doesn't make use of any hardware acceleration (NO OpenGL). So although it might look similar to professional applications like Google Earth or Nasa World Wind it's rather meant to be a small light weight multi purpose widget for KDE. Still Marble comes already with basic Google Earth KML file support and therefore Rainer Endres sat down and did some script magic to convert the data on KDE WorldWide to KML file format.To improve the very basic placemark rendering I added some code to make sure that the labels don't cover each other. So here's the North American KDE Community in all its beauty (Say "hi" to Aaron, Jason, Chani, Annma, Jeff and all the others): Of course the algorithm in place can't compete with more sophisticated automatic label placement methods (like Simulated Annealing), but judging from the result it's a good start - especially given that it's not optimized yet at all. If you want to try it yourself these are the steps that lead to instant success: Make sure you've got SVN and at least Qt 4.1 installed svn co svn://anonsvn.kde.org/home/kde/trunk/playground/base/marble cd marble ./buildqmake qmake (make sure that the parameter refers to Qt4's qmake - on Kubuntu you have to type in buildqmake qmake-qt4 "). make Now download Rainer's fresh KDE Community KML file and save it in the "marble" directory that you have just created. As a last step execute: bin/marble ./kde-devel-locations.kml and Marble is ready to roll ... Have a look at the fine work of my coworker Slartibartfast and see the Trolls while you're near. And as you're there already don't forget to register for the 10-Years-KDE anniversary party: You might win a Qtopia Greenphone if you do so ;-) . Last but not least I'd like to thank Joseph Wenninger who did an initial port of Marble to cmake right after I had commited Marble to SVN.

I want to run a survey about Gwenview. I have been googling for some web based surveys for a while, but it would be even better if I could get some real experiences. Read More

We did not advertize it a lot yet, but as a few people already know, kde will have a generic board application :) We did a 0.9 alpha release a few days ago, immediately after moving to kde svn, but development is going on. The features in the release include a very generic board game support (at the moment only C++, but lua variants will be supported very soon, games implemented are chess and a few variants, connect four, reversi and chain reaction. Shogi is coming :)), an animation engine that supports contemporary animations, eye candies, etc, a lua-scripted theme loader that can load SVG, PNG, TTF chess fonts, and create images on the fly, and a move list widget that allows for comfortable pgn editing. Support for playing/observing/examinating chess (and chess variants) games on FICS is almost complete, support for chess engines is at a good stage of development (but it is not very usable, yet). Since the release i've been implementing a generic option framework (with lua bindings), to allow themes, variants, etc to get an integer options from the user (through a spinbox), or a bool (through a check box), as well as a color, font, url, etc. On the other side Paolo (zhw on IRC) has almost finished the port to kdelibs (we were using Qt4 only, but kdelibs really rocks and we will no longer support the qt-only version), and is rolling out a very generic XML settings class set, that will be much more powerful than the alreay available QSettings or KConfig. Ah, as you can see in the second screenshot, i could not resist to use KHTMLPart to implement an alternative move list widget, with less eye candies, but more in the chessbase style and that i also hope will make easy printing games (babaschess has two alternative move list widgets too, so i guess that keeping the choice should be ok in kboard too :)). I think that the option and settings frameworks are pretty good pieces of code that may also be reused in other projects, but we'll have a better idea after using them in kboard for some time. On the down side, we still haven't decided how the user interface will be, we do not really feel comfortable with QDockWidgets, (for instance, the console when detached will always want to stay on top), so we are planning to give a look at the IDEAL mode, but if some GUI guru can suggest us better ideas any help will be welcome :) You will find more screenshot on http://kboard.sourceforge.net (ah, the website is another thing that desperately needs to be improved).

KDE is going to celebrate it's 10th anniversary. We'll have a birthday party on Friday, October 13th, 2006 in the Technische Akademie Esslingen in Ostfildern (near Stuttgart). More information is available at: http://events.kde.org/10years If you register by Oct.11, 9:00 UT you'll be entered in the 10-Years-KDE raffle where you could win a brand new Qtopia Greenphone offered by Trolltech! So, hurry up and let us know whether you'll attend! Participation will be possible for everybody who registers in time and we are happy to welcome the winner in our large community of KDE and Qt developers. Of course you also need to attend the event and be present at the raffle ceremony at 16:00 CET in order to qualify for participation. Excluded from the raffle are the members of the party organisation team, the speakers of the event as well as Trolltech's employees.
