Dirk Hohndel talked about his experiences with QML and Kirigami at LCA 2019: Producing an application for both desktop and mobile I think that's quite useful for us as feedback from somebody who is not directly part of the KDE community. Read More

Hi, there is a new book on CMake (there are not many): Professional CMake - A practical guide. I haven't read it yet, so I cannot say more about it, but I guess it should be useful. Read More

In the last days I had to deal with loading plugins via dlopen. I learned so far already a lot about symbols on Linux. I expected, that if I have an executable, and load a plugin into it, that the stuff inside the executable (i. Read More

Sorry, for posting this on blogs.kde.org, but I think it might help a few people out there having the same problem. So, if you want to get webex working on a 64bit Linux system, basically all you have to do is make sure that all necessary 32bit libraries are present. Read More

You are a student, you would like to contribute to an Open Source project, and get paid for it ? Then I may have something for you. At my job at Fraunhofer in Kaiserslautern we are using the CDash testing server for testing the software we develop - various different High Performance applications for Linux clusters. Read More

Since I don't have an account to reply there http://blog.rburchell.com/2011/12/why-i-avoid-qregexp-in-qt-4-and-so.html, I'll do it here. Recently somebody benchmarked regexp libraries as potential candidates for use in CMake. Short version: PCRE was not exactly much faster than what is in CMake, re2 and TRE were magnitudes faster: [cmake-developers] Re: slow regex implementation in RegularExpression. Read More

Welcome to the third part of this small series about new stuff in CMake 2.8.6, following the first and the second part. Most non-trivial projects, whether built with CMake or something else, depend on multiple other packages, which can be either optional or required. Read More

After introducing the automoc feature in my last blog, here comes the next part of this series. More will follow. The new --find-package mode of CMake Typically, in projects which are built using autotools or handwritten Makefiles, the tool pkg-config is used to find whether and where some library, used by the software, is installed on the current system, and prints the respective command line options for the compiler to stdout. Read More

Starting with version 2.8.6 CMake supports what is known as automoc, i.e. automatic handling of moc when using Qt4. As you know, when adding signals and slots to a class using Qt, this source code (typically the header) has to be processed by the moc preprocessor. Read More

Hi, you like KDE and you want to support it ? Here's an easy way to do it: The german bank ING DiBa is giving away 1000 Euro each to 1000 associations. Read More

Hi, the KDE buildsystem BoF/meeting/whatever you want to call it/ will be Monday, at 8:00 PM (i.e. in the evening) in the restaurant/cafe St.Oberholz: http://www.sanktoberholz.de/?page_id=13 According to Claudia they are used to geeks sitting around and discussing :-) Read More

So, to make it short, I'll be also in Berlin at the Desktop Summit, from Saturday to Wednesday evening. So if you have wishes, questions, want to contribute to the KDE buildsystem or CMake, just look around for me :-) There'll be a KDE buildsystem BoF . Read More

I'm back now (since two weeks already) from the KDE Platform sprint in Randa and I have to say it was great. Randa is located very nice in the Swiss mountains, next to Matterhorn, and very well suited not only for KDE sprints, but also for cycling (I had my bike with me there) :-) Read More

Until last week I was still running good old Slackware 12.1 with KDE 3.5.something. I had skipped Slackware 13.0, because it had still no support for virtual screens in X/xrandr, and the KDE 4. Read More

Just a short cmake tip today... You probably know that with "cmake -DSOME_VARIABLE=foo" you can give variables to cmake. Now, sometimes, e.g. if the wrong version of a package has been found, e. Read More

Hi, just to let you know, our friendly buildsystem developers from Kitware are progressing on their plan towards world domination ! ;-) While their main offices are in the US, in beautiful upstate New York, they recently opened their first office outside the US, in Lyon, France, where e. Read More

Indeed, I've got good, no, very good news from Real Life ! :-) About one month ago me and Antje married, so she is now Mrs. Neundorf :-) The weather that day was slightly rainy and misty in the morning, but became better as soon as we were married, and we had a great party in the evening with our relatives and friends :-) Read More

Ok, this blog is not really KDE related (well, it makes the network installation of a KDE developer more convenient, so...), but anyway here we go. Main purpose is to get the compatibility information out there, so others can find it. Read More

I'm just trying to compile Battle of Wesnoth (yes, for me gaming means compiling games... ;-) ). I just built it with CMake, which first complained that it didn't find Lua 5. Read More

I thought I share a few interesting links: Gnome switches to git: http://mail.gnome.org/archives/desktop-devel-list/2009-March/msg00086.html But not everybody does so, e.g. Python is switching right now to Mercurial: http://mail.python.org/pipermail/python-dev/2009-March/087931.html Eric Sinc has an interesting blog about DVCSs: http://www. Read More

Hi, today at work I noticed something strange. My box there has kUbuntu 7.10 (yes, I know, quite old, but does what it is supposed to do). I have an awk script which I want to use to process a text file consisting of 4. Read More

Hi, in the good old times(TM) using Linux was simple. If you wanted to access some drive, e.g. CD-ROM, floppy disk (you know these 3.5" square plastic things which could hold a whopping 1. Read More

Hi, just out of interest, where is Gnome heading these days ? I'm a bit confused. There is Gnome2, which are applications written using libgtk2, mostly in C (also some Python and C#). Read More

Hi, in KDE 4.2 we have quite a few changes regarding the buildsystem compared to 4.0/4.1. Also we require at least CMake 2.6.2 now, which alone brings a lot of new features. Read More

Since some August or so we are now requiring CMake 2.6 for KDE svn trunk. One thing was has been added and which is very nice support for the new environment variable CMAKE_PREFIX_PATH. Read More

I think we are getting one step closer to World Domination (TM) of Linux ! ;-) How come that I think that ? Have a look at that page (it's german): http://www. Read More

Back in April I did some very rough performance measurements of my new notebook vs. my desktop machine: Back then I got the following numbers for a complete build of CMake: Read More

Last week I upgraded my development machine, from a AMD Athlon XP 2000+ to an Intel based one, featuring GMA3100-based onboard graphics. Everything's working smoothly that far, I have only one issue: "Virtual" keyword in the "Screen" section seems to be ignored. Read More

KDE svn trunk requires [http://www.cmake.org CMake] 2.6.2 since last week. Version 2.6.2 has been released just a few weeks ago, so maybe there are not yet packages for all distros. Read More

There was this blog entry about the state of packaging for the Mac. Containing "Then you think to yourself, if only those nice boys and girls in KDE-land had a native solution for installing their software," Read More

Just a short note: yesterday I booted my laptop with a brandnew kubuntu 8.10 beta CD. How to put it, this rocked so much !!! KDE 4 really is beautiful ! Read More

This year was just my second Akademy. And as my first one, two years ago in Dublin, it was a really great experience again. Actually I don't know where to start. Read More

Since a few days Kitware is hosting a cdash dashboard for kdelibs. The ctest config file in kdelibs svn has been adapted accordingly. So if you run now "make Experimental" in kdelibs the build and test results will be submitted to http://www. Read More

As Friedrich already noticed, blogs are where discussions happen nowadays... Well, also responding to one of Ade's posts, where he states "I've been starting CMake "experimental" builds on various Solaris machines with SS12 to get numbers on how many warnings and errors we're producing. Read More

This year I was again at LinuxTag, after I missed the one last year. LinuxTag in Karlsruhe was always very nice, the one two years ago in Wiesbaden somehow didn't feel that good, but this time in Berlin it was really great again. Read More

So this blog title is "KMail and bikeways in Germany". You may wonder what they have in common. You may wonder whether there will be an eloquent Aaron-style nice little story behind that. Read More

Ok, we all know, blogs are the new mailing lists, so here just some quick comments from my side on all the release-cycle stuff. About being in sync with releases of other projects: I am caring for our buildsystem which uses CMake, so the releases of CMake and KDE matter to me. Read More

I don't know why, but often I have the impression that KDE fonts are quite big, and this can be changed by modifying the X11 dpi settings. Let's head over to good old Slackware. Read More

Different groups of people use different ways to measure performance of computers. Kernel developers test their kernels by, well, compiling the kernel. KDE developers may measure the startup time of KDE. Read More

A few days ago I asked in the blog "where to buy a 14 inch non-glossy notebook with Linux in Germany". I received quite a few responses and emails, thanks a lot for the support ! Read More

Ok, so because the old notebook is starting to fall apart (it is probably around 5 years old or so) I need a new one. So, I want to buy a new notebook, nothing too fancy: 14 inch, non-glossy, Intel Core Duo, Intel Graphics, Intel WLAN, 1GB RAM, price at most 800 Euro. Read More

I just decided for myself I should try to use a text based presentation software, since GUI-based presentation apps require you to think about what goes on which page from the beginning, usually you see only the current page, you have to think about the layout (fontsize, decorations etc. Read More

SCNR. Rejoice - it has been done - KDE 4.0.0 has been tagged ! :-) Although I didn't touch any significant number of lines of C++ code of KDE for the 4. Read More

Around 2000 (back in KDE2 times) I wrote the so called LAN information server lisa (http://lisa-home.sf.net), which can you show the neighbours in your network. This works by regularly sending ping packets on the network. Read More

Two weeks ago I moved again and it took until yesterday that I got internet access again, now using cable. This actually rocks, it is really fast, 6 Mbit/s. I still can remember, I think it was in 2001 I still had an analog modem with 100something kbit/s. Read More

Hi, CMake 2.6 will rock. Latest news: Clinton Stimpson has started to work on a Qt4 based GUI for CMake, so there will be a modern GUI to CMake also on UNIX, here's a screenshot from CMake cvs today: [image:3080]. Read More

so since 6 weeks I'm now working at Kitware, Clifton Park, NY, USA. Since it's the first time that I'm in America this means a lot of new impressions for me. Read More

Some of you may already know it, but I thought I should announce it here: next Thursday I'll be going to Albany/New York for around 6 months. There I'll have a job for this time at Kitware, you know, the guys who are (among others) writing the best buildsystem in the world ! Read More

do you still have CMake 2.4.3 installed on your KDE4 development system ? Then it's time to upgrade to CMake 2.4.5 or newer. Because starting Monday in a week, March 19th, at least CMake 2. Read More

So this year I was the first time at FOSDEM in Brussels. Brussels is a very nice city, I didn't expect this. It reminded me on Paris, it has the same french flair and beautiful architecture. Read More

So finally I decided to do a completely fresh install on my notebook, a Dell C640. If you are looking for a notebook which is good supported by Linux and FreeBSD, I can really recommend it, everything works out-of-the-box. Read More

So, in the last days there have been several things which made me think "This rocks !". Wanna know what ? So here we go, without any special order. Sun releases Java under the GPL ! Read More

Recently it seems to me that Ruby is now really taking off, everywhere you hear news about it. You know, there is Ruby on Rails, which is really the hype nowadays. Read More

So today I tried to optimize some code using std::string from the Standard Template Library and found something interesting. Let's say you have strings to assign which sometimes get longer and then again shorter. Read More

Recently it seem a lot of projects are switching to CMake. Just today I read the news about Debian forking cdrecord and almost missed the little note near the end of the article: "For our fork we used the last GPL-licensed version of the program code and killed the incompatibly licensed build system. Read More

Wanna chat directly with other cmake users ? Ask questions ? Exchange your experiences ? Share your cmake scripts with others ? Let the world know how much you like cmake ? Read More

Hi, now that I found that skype for Linux doesn't support video, is there a good solution ? Ekiga ? Or FFserver on both ends ? Is ffplay able to ffserver streams ? Read More

Hi, well, imagine you find something in cmake which doesn't work or there is something missing. Now, luckily enough, cmake is Free Software, BSD licensed. So, you can just have a look at the sources, write a patch and send it to the cmake developers at cmake@cmake. Read More

Just in case you didn't know yet: Dirk Mueller won the german championship ...as if hacking KDE wouldn't be enough ;-)

Ok, so finally I'm back online. When I came back from LinuxTag last sunday, my development box didn't boot anymore :-/ It took until today to get it working correctly again (RAM, mainboard, power supply were suspect). Read More

So I fiddled around with hardware last week, accepted that my board really doesn't like DDR400 RAM and got my first SATA disk working, main problem were BIOS issues. Well, finally I have enough disk space for the complete KDE/trunk/ again :-) Read More

svn is slow. Ever tried svn commit or cleanup over trunk KDE ? I started a commit, pressed Ctrl-C to cancel it. It didn't cancel within maybe half a minute. I killed it with -9. Read More

Hi, well, since it seems some discussions are nowadays done via blogs, let me say something as reply to [http://aseigo.blogspot.com/2006/04/cmake-sadness.html | CMake Sadness] by Aaron. So, building KDE is a huge task. Read More

Hiya, the results of the 2005 LinuxQuestions.org Members Choice Award are there. Although the announcement: "Among the winners are Ubuntu, Firefox, MySQL and OpenOffice.org." doesn't sound too good for KDE, here's a (only slightly) closer look at the result :-) Read More

Well, if you want that, you can have it today for trunk/KDE/kdelibs/. The cmake ( http://www.cmake.org ) developers have been so nice to setup a dashboard for KDE: http://public.kitware.com/dashboard.php?name=kde If you build kdelibs/ using cmake, simply enter "make Experimental" and the results will end up there. Read More

Hi, just now the first complete compile run of trunk/kdelibs/ finished using cmake as build system. :-)) Only minor things are still missing: khtml (gcc 3.2 is not able to compile it), install rules for headers, some configure checks are still missing. Read More

Some weeks ago I blogged how I managed to compile kpager using cmake. In the meantime the am2cmake script was a bit fine tuned and now even more works. The script and the KDE 3 support files for cmake have finally entered KDE svn, so you can get it from here: http://websvn. Read More

Hi all you artists out there, I need an icon for cutecom, a cute Qt replacement for minicom. Anybody outthere who can help me ? Thanks Alex

Hiya, here's a very simple way to get a performance number for KDE: $ time konsole -e sh -c exit This gave me the following numbers: 0.75 seconds on a notebook, Sempron 3000+, SUSE 10. Read More

Hi, in the screenshot you can see a different kpager than the one you know. [image:1667] So, what's different ? This kpager is built from the same sources, but neither using autotools, nor unsermake, nor scons. Read More

Last week I updated my notebook from Ubuntu Hoary to Breezy. I was very pleasantly suprised when I noticed that they decided to make the "Simple Browser" profile of konqueror the default profile. Read More

Hi, as I mentioned previously, I'm trying to build kdelibs (still 3.5, not 4.0 yet) using cmake. To make it short, yesterday it managed to get to build kwallet, where I discovered that I missed to insert a check for sys/types. Read More

As time goes by KDE distributors come and go. It seems in the meantime I'm one of the more long-time contributors, I got my cvs account late 1999 I think (with low but quite constant activity. Read More

Hi all, so now I'm back from Paris, now already almost for two weeks, where I visited the finale of the Tour de France this year. It was a great experience :-) Read More

After todays stage only 2:12 left to the 3rd place ! Go Ulle ! :-)

I'm a bit late, but I also want to share some of my impressions from LinuxTag last week. As always it was fun. It's always nice to meet with other OSS developers, be it gnomes, X devs, the mplayer guys and of course, our KDE fellows :-) Read More

Hi, maybe you know it already, but I just learned it last week from Carsten at LinuxTag: if you have an email account at gmx, enter "webdav://mediacenter.gmx.net" in konqueror (or any other KDE application), and you get access to the mediacenter area of gmx. Read More

There is the myth that using C++ per se makes applications and libraries slow and bloated. Avoiding bloat is of special importance for embedded devices, which usually have limited amounts of CPU power and memory. Read More

So finally I'll also try to start blogging since nowadays everybody seems to do so. So, most importantly, the sun is shining today here. Nice wheather make me feel good :-) On the more KDE related side of things, now I also tried the famous kUbuntu distro. Read More
