 So… no-one responded with anything helpful on my last post. There was a Dot article about the semantic desktop (and hence Nepomuk), however. On to more interesting things. I’ve got fed up recently with changing volumes for different songs. I actually notice it more on my portable MP3 player, but Amarok 2 has long bugged me by not having any Replay Gain support. And I’ve been thinking about implementing it for about the same amount of time. Yesterday, I finally got around to starting it. The first hurdle I came up against was how to get the information I needed from the files. If you run mp3gain or aacgain on your MP3 or MP4 files, or if you have MusePack files, there’s no problem since the information about changing the volume ...read more...

| I spent a little time yesterday working on a class that provides
a wrapper around the MediaWiki API. It makes quite a nice example
of how the QNetworkAccessManager API can be combined with
QXmlStreamReader to quickly access web services. The code, as you'll
see, is very simple. First lets take a look at the constructor and the data members. We
specify the path to the api.php file of the wiki we want to query,
and setup the network access manager. struct MediaWikiPrivate {
QStringList results;
QUrl apiUrl;
QNetworkAccessManager *manager;
int maxItems;
};
MediaWiki::MediaWiki( QObject *parent )
: QObject( parent )
{
d = new MediaWikiPrivate;
d->apiUrl = QUrl("http://en.wikipedia.org/w/api.php");
d->manager = new QNetworkAccessManager( this );
d->maxItems = 10;
connect( d->manager, SIGNAL(finished(QNetworkReply*)), SLOT(finished(QNetworkReply *)) );
}
People using the class can ask us to perform a search by calling
the search() method with the term they want to look for. Again,
the code is simple. void MediaWiki::search( const QString &searchTerm )

| 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. So, if you want to know what has changed, IOW, if you are a
KDE developer or a packager or somebody writing about it, you can find a (hopefully) full list on TechBase:
Changes in the buildsystem with KDE 4.2. Alex

| I’ve been quite productive today - committing peoples patches that needed to have the trunk freeze lifted. Already we have for KDE 4.3: - History importer for Pidgin logs
- A new ‘View History’ button in the chat window
- A chat window that now follows the background setting from the config
- A dependency on an external libgadu rather than providing our own static copy
Thanks to everybody who contributed during the freeze. Keep ‘em coming!

Prologue
It's probably the first time in my life when I'm writing a post with a word "Review", but looks like it's a perfect time to start doing that. Right now I desperately need to tell the world about KDE4, or to be precise, soon to be released KDE 4.2. This is going to be the first "real" release targeted not only at KDE developers and enthusiasts, but at general public - all the people who eagerly waited for the next KDE desktop to arrive. With this review I'd like to let people know that the KDE 4 is ready and to once again celebrate the hard work of all the people who put tremendous effort creating this great desktop.
Now you may think that because I'm a KDE developer, this is going to be one more "fan boy" article about KDE4, but I hope I'll prove you wrong. There are things I like, things I hate and things I miss in the new desktop and I am going to write about all those things. Of course everything that ...read more...

| Yesterday I woke up, put some clothes in a bag and drove up to Hengelo to pickup Bertjan and go to the PIM-Meeting. The drive was fine. In some of the narrow streets of Osnabruck the roads were a bit slippery, so I could verify that my cars traction control was working just fine and it informs me that it is working due to flashy light on the dashboard. Good to know that.... At the meeting we started right away with addressing some of the pending issues. It is amazing how much faster you can get all to the same page when you are in a face-to-face meeting. Like evaluating the Akonadi migration. We all agree the beta period has been pretty good in that regard. A lot of distro's made changes in the packaging and we got a good overview about which areas need a bit more work. And that's exactly what the goals were. We also talked about kdepim runtime split and the move of akonadi to freedesktop.org. Kevin already blogged about that earlier, so no point in ...read more...

Recompiling kdelibs, kdepimlibs, kdebase, kdesdk, kdeplasma-addons, playground/base/plasma all in all takes about 2h 13min on my t41p (1.7GHz, 1.5GB ram). It's still quite fast imo, but I imagine with today's hardware it's maybe 30 minutes? See below for detailed infos. I'm using mpyne's excellent kdesvn-build scripts to build KDE from trunk. I even believe this should be the default way for building trunk instead of the rough road we propose on techbase right now. Are there any reasons not to use kdesvn-build?

If you’ve been to KDE-look or sites like Interfacelift, you’ll know that people love their wallpapers. Although there are some guidelines for “What makes a good wallpaper?” it still often remains a matter of personal taste. And Nuno’s recent wallpaper is one of my favorites: 
The funny thing is that this wallpaper also seemed vaguely familiar to me. Last night, I remembered why: A few years ago, I was trying to take some photos at night during a snowstorm and my auto-focus was catching different flakes and refused to cooperate. I didn’t notice this until after reviewing my first shot, which looks like nothing in particular it’s so abstract: 
I’ve put two 1920X1200 versions in my image gallery if anyone wants an inferior version with a story behind it. Anyway, great work Nuno, I ...read more...

I went looking for a library interface to git tonight. (I can already hear some of you laughing.) Turns out that my assumption that there must be a nice git library out there somewhere might have been a bit .. naive.
Git itself makes an archive of the common files that it uses in its various C apps and links those into each app. In what can only be a fit of humor, it calls this thing a "library" in its Makefile.
Yes, more humor: a naked Makefile. After all, real mean don't use pansy tools that might make life easy like configure of cmake, right? Anyways .. I really didn't go looking for a build system, I went looking for a library I could use to interact with a git repository.
Why a library? Well, I really don't want to be running external commands and then parsing their output. Unfortunately that seems to be what most other apps that provide git fronts seem to be doing.
I got slightly excited when I saw the ...read more...

we’ve got a bit more in hte way of javascript bindings, and only one of my teachers has posted homework, so I decided to work on kconfigmenu some more. :) now that it can install and run, I want it to display a pretty icon. so, first thing, we create an icon:
icon = new IconWidget();
icon.setIcon(”configure”);
re-using kde’s confiugure icon once again. :)
but it turns out that plasmoids have no layout by default, and that’s not good… so at the top of the file we have to create one, and then after out icon is made we have to put it in the layout.
layout = new LinearLayout(plasmoid);
icon = new IconWidget();
icon.setIcon(”configure”);
layout.addItem(icon);
now, unfortunately javascript plasmoids are defaulting to 200×200 on the desktop, and if i try to resize my plasmoid it overrides the configured size every time plasma restarts (a Bad Thing). that’s gonna have to be fixed in the bindings; until then, I start with a ridiculously ...read more...

 Matthias Kirchner has sent me the FSFE's New Years Resolutions. A good opportunity to zoom out and think about why we're doing KDE. A happy new year to everyone. Keep on rocking in a Free World.
In more mundane news, I'll be going to Camp KDE on Jamaica next week, looking forward to see wonderful people I don't get to meet too often (excluding Ade who I do meet more often, but not on that side of the ocean). As it's cold and snowy here in the Netherlands, too cold for my taste anyways, I'm also looking forward to charging my batteries with a bit of sun. More so, if that involves hacking and discussing with the nice people going there. Early February, you can find me in Portugal again, where we (the Plasma team) will be having a ...read more...

Most of us developers are so acccustomed to syntax highlighting, that we couldn’t live without it. Within the last years, it happened to me a few times that I had to look at C++ code with an editor that does not have it. Every single time my initial feeling was that I was looking at a large unstructured text-blob, totally unreadable. Putting some additional cognitional energy into the task, I was able to solve the problem in the end, but there is no doubt that syntax highlighting does increase productivity, it is not just eyecandy. Syntax Highlighting
Now the first interesting question is: What exactly is it about syntax highlighting that makes the text easier to work with? When trying to understand what the code does, we usually first try to recognize its coarse structure. For that, we need a fast overview of the code. With that overview, we can decide where we want to continue concentrating on. Now the problem is, while building this overview, really many words have to be scanend. Actually reading all of ...read more...

I am glad to announce that choqok my most favorite Twitter client (well only for a week or so ;-) is now available for Kubuntu Jaunty as well as Intrepid-backports (a.k.a. unsupported updates).
I must admit choqoK looks very promising and can probably also become a very awesome non-twitter micro-blogging client. I guess the lead developer could use some help, so if you get a minute or two: check it out and maybe come up with some feedback or even a patch or a piece of translation or a handbook... ;-)
Have fun with 0.2 meanwhile.

I've been running KDE4 desktop since May and I've constantly suffered from poor desktop performance and various graphics card related problems. Now I've solved those problems: I've bought an ATI card. Despite NVidia releasing the new Linux driver and suggesting to tweak several performance-related configuration options, I still decided to go and spend $50 on the new video card. Here is the long story why...
On my NVidia GT8600 KDE4 had several types of performance problems:
1. Slow repainting of windows
When I used KWin as a window manager with disabled compositing (sic!), main windows of KDE4 applications took too much time to repaint themselves upon switching. When I used other window manager (twm for instance :)), the repainting was a lot faster. Measurements showed that KWin suddenly took more than 40% of CPU on window switching. Turning on compositing (aka "desktop effects") greatly improved KWin performance, but compositing was a no-go for me for the reasons I'll explain below.
Status of the problem: could not be solved for ...read more...

| Do you think that you have significant amount of experience to work as a mentor at KDE forums? Then you should consider joining the team! Read on… What do mentors do?
Mentors are responsible for conducting Klassroom sessions. For those who aren’t familiar with the KDE Forum klassroom concept, read this post.
You will be conducting a “Kourse” (lesson) at the Klassroom area. The lesson can be something like “Fixing XYZ bugs” or “Documentation kourse for project ABC”. You will guide a team of “students” (who will apply for your kourse beforehand). Your motive will not only be to contribute to KDE but help them learn how to do so. Why are mentors needed?
With the great success of the klassroom concept, we are looking forward to have more sessions (at higher frequency). For that, we would need more contributors who can undertake and organize sessions. Existing mentors are listed here. What all would you have to do?

Over on planet.gnome.org, Ted Gould blogs about how the current system tray protocol sucks. I've written about the systray recently, but I started writing about how much it sucks 5 years ago. I wrote about it in a number of places, and sent mails to the xdg list.
Of course, I was always busy with one more thing and nobody else really seemed to care. In fact, some told me I was being silly and the current system was just fine. I wonder if those people even remember. =)
In any case, it seems like hell is finally freezing over: we have a system tray widget in 4.2 that is built for multiple backends (and already has a couple) so that we can freely mix and match old with new as a realistic path forward, and people in other projects are talking about doing actual work in the same area too.
Hopefully Ted isn't going to make the same mistake I did, which is ...read more...

After 2008's Tokamak in Italy, I blogged about scripting and my cracktastic thoughts on it. I mumbled on about ninjas and myspacers and apparently the drugs are still in my system because I still think it's a solid approach to the problem.
Thankfully I was able to convince a couple others of that as well and the widgets API we put into libplasma, which really just wrap plain QWidgets-in-QGraphicsProxyWidgets thereby taking the boredom out of using them and giving a nice scripting-friendly view on them, was one result. The other was the JavaScript AppletScriptEngine in kdebase.
Rich Moore started the work on these and got a fair ways into it. Then he got busy with his day job. Then he got really busy with his day job. We talked about it on IRC a bit, and I said I'd try to help pick up the slack. Chani and I ended up doing the widget API and Rich got some more work done on the script engine. Then Rich got really, really busy and things ...read more...

well, the first day of a new semester is over. it’s been a fairly good day. the burnaby campus was closed (even though buses were running) but the surrey one was open, and all my courses are there. the first course was cancelled anyways because the teacher didn’t think he could make it. :) I got my upass, sold an old textbook, managed to get into the bookstore at a time when it actually had no line and buy one of my textbooks, and discovered I’ve got a friend in each of my classes. macm 316 looks like it’s going to be annoying (the teacher has a thick accent and mumbles), but cmpt 383 will probably be quite interesting. how much time I’ll have for KDE this semester remains to be seen, but I *am* going to campkde, and there’s another tokamak soon (oh god I hope I can keep up with my courses with all this travel) so if all else fails I’ll have a chance to hack then. :) aseigo and notmart’s work on the qtscript ...read more...
