 DataEngines written in JavaScript can now offer Services. Sounds life changing, right? Ok, maybe not, but really, I swear it is! ;)
DataEngines publish data in a read-only pattern that allows the data to be accessed and shared by multiple consumers (or what we usually refer to as "visualizations"). The "read-only" part is a bit of an annoyance if the data being presented represents a live artifact. For instance, if a DataEngine was reporting on the network link, it might be nice to set the status of that network interface. Of if the DataEngine was publishing information about windows on screen, it might be nice to be able to say, "Hey, minimize that one." Or if the DataEngine shows information from an online service, it might be really useful to say, "By the way, here are my log in credentials for that service."
Plasma has the concept of a "Service", which does pretty much what it sounds like: it provides an interactive service that you can make calls to. What those calls do, exactly, is completely up ...read more...

We are in full swing of electronic books, bubbles that are likely to explode into a new phase of the war between the old and new generations of publishers, content providers and consumers. It is likely that sheet music enter the battlefield.
Before proceeding I must warn you about two facts. One: despite the name of the blog, I am a Trekkie. Two: I am not a neutral observer. In my opinion traditional books publishing, as well as media labels, are going to lose. Those not able to adapt to changing times will disappear. Resistance is futile.
The musicians are going to adopt electronic lecterns sooner rather than later. The electronic scores begin to replace the editions printed on dead trees, as is already happening with books. There are some solutions on the market, more or less primitive.
MusicPad: Hardware and software.
How could you describe it? It is like a Kindle with legs. There is a "Master" version with twice the surface. Among its outstanding features: it is completely silent. ...read more...

This is a quick follow-up on my post from yesterday about adding content to Userbase and Techbase.
The good news is that two people (besides myself) have started adding content to the Plasma Panels page. There's a discussion thread with three people (including me) adding to it. This is great!
I added some links in the introduction section to text that refers to specific widgts, such as the system tray and tasks widget. If you're looking for something even more focused than "Panels in Plasma" to add to, log in to Userbase and click on one (or more :) of those links and start adding content.
I've also added the {{improve|reason why}} template from Techbase, and used it on the Panels page. This in turn gives us the auto-generated Needs Improvement page thanks to the use of categories. Looks like a nice start to getting lists together. I need to discuss with Anne about adding a Category to the {{under_construction}} template so we can start ...read more...

Richard Hillesley wrote an articled title "Copyright assignment - Once bitten, twice shy" that was published today. When boiled down its essence, Richard said two things in the article:
- Forced assignment of copyright raises the barrier to participation and therefore limits the amount of participation.
- When someone else owns rights over your work, they can do nasty things to them.
Both of these statements are true. They are also not without provisos. Richard noted that the FSF provides a promise that it will never close the software up, for instance, which makes point two a matter of diligence: if you assign your copyright to someone without anything in return, such as a guarantee of how those rights will be managed (including termination of said rights should the other party break that guarantee), then you have just made a huge mistake.
It's not all roses for projects that avoid copyright assignment, though: Richard notes the four years that the Squeak community has spent trying to get a license change through. When it comes time to defend ...read more...

I had the pleasure to meet Aleix Pol and Stu Jarvis at Akademy. They guided me the way to KDE EDU and scientific apps for KDE.
Weeks later I am sitting in my office doing some statistics. The funny thing is, that your brain sometimes is useful and I remembered an app called rkwrd or something.
My friend google told me that it is called RKWard and that it is not a KDE Application. It is an application based on kdelibs (it I see that right).
At home I fired up my kBook and installed the packages for r and RKWard. After a quick look into some of the nice tutorials I could do my first analysis and the linear regression I wanted to do. Brilliant. What a fantastic application. And I had such a hard time during my studies calculating statics by hand.
The other advantage is that I am reminded that I wanted to invest more time for the promotion of KDE EDU (inculding ...read more...

Today is my last day at Qualcomm. It still feels like yesterday when I set foot in this continent, started some fun with X2, enjoyed Brazil, had this meet-up in Cupertino, did little exploration around San Diego, and then got blessed with a cute boy. Time really flies. Now it's already time to move on, again (though this time without a geeky resignation). I will miss Snapdragon (the pictured HTC EVO is powered by the said platform). Or any other dragons. Those who are annoyed by a certain obsession of mine probably can guess where I'm heading to. In the grand mission of inspiring and pushing developers to write better and more exciting applications, a particular productivity barrier needs to be broken. And I dropped enough (subtle) hints in my previous ...read more...

| KDE 4.5 will be released in the next days with the most polished Kate/KWrite and KatePart during the KDE 4.x series. A lot of work went into fixing bugs and cleaning up old code for this release. Many important aspects where redone, just to enumerate a few: - encoding detection & handling
- the text buffer
- the undo/redo system (thanks Bernhard)
- search/replace (thanks again Bernhard)
- handling cursors and ranges
- improved spell checking (thanks Michel)
- improved indentation (thanks Milian)
- speed improvements (Milian too)
- better JS scripting (Dominik)
- porting of KDevelop to new interfaces (David Nolden)
It will be the most unit-tested release of KatePart ever I guess, but still a long way to go until we have a good test coverage. (we just scratch the surface) Many thanks to the people contributing to this release (not only to the ones named above or below!), without that much helping hands, never such an amount of cool stuff would have happened  I guess one of the real kickoffs was the great Kate/KDevelop sprint in Berlin, handled by ...read more...

| I just released version 0.2.1 of Colibri, the passive alternative to KDE4 plasma notifications. Here are the most important changes. On the notifications themselves: - Consecutive notifications are now merged. This is quite handy when someone sends you three consecutive messages on IRC for example: instead of showing three bubbles on after the other, the current notification will grow and integrate the next message. This only happen for notifications from the same application, with the same title.
- The notification bubble follows the Plasma look more closely: it features the same background halo behind text and can take advantage of blurred background when running on KDE 4.5.
The configuration module has been improved as well: - It is now possible to select on which monitor the notifications will appear.
- A "Preview" button has been added.
- It is easier to setup Colibri on your machine: the configuration module will warn you if another notification system is running and let you start Colibri if it is not running.

| I frequently find myself wanting to look through the Qt source or look through a couple of commits. I could keep a copy of Qt checked out on all the computers I use, and flick through the repository using git command-line or qgit or even git instaweb, but this is usually less convenient than simply heading over to gitorious. Unfortunately, gitorious is notoriously sluggish and I find their site design a bit hindering as well. So I’ve decided to mirror Qt’s repository on my personal server running cgit, which is much much faster than Gitorious. It’s synced once an hour by cron. And if nobody abuses this, I’ll keep it open for the community. I’m not sure if I’m syncing it in the ideal way, however. I ran git remote add origin git://blabla, and then I run this to sync: #!/bin/sh
cd $(dirname "$0")

Marco's been doing some more amazing work on Plasma Mobile. Given that its running on a device with a 2+ year old Intel mobile CPU, this is pretty cool:
Marco and I have been making progress on the Plasma Shell Design document as well, on step at a time. A lot of the information that is there is being externalized from our minds for the first time ever, and it's really long overdue. Some illustrations of things like the usage of the different quadrants of the scene for different kinds of items would be nice, but are beyond my skill to make look nice and professional. Still, progress... :)
I also did a small proof of concept yesterday, when Aaron P. came up to visit from Washington so we could give him a jumpstart on KDE development, that answered the question: is the current Javascript-based Plasma Shell Scripting powerful enough to use to write a Javascript that could be fed back in through the Plasma Shell Scripting ...read more...

| The release train keeps rolling on… In one week both Muon and QApt 1.0 will be released. Until then, here’s one last pre-release to iron out any remaining issues before the stable release. Packages are in the normal place, and sources for QApt 0.5.0 can be found here. (Muon 0.5.0 sources will be uploaded in the usual place once I get back to the hotel… unfortunately I cannot do the GPG signing of the tarball on my grandparent’s computer) Here’s what’s new since last week: QApt 0.5.0 - No coding changes, but there are now a weeks worth more translations for the qapt-batch utility.
 Go, go kde-i18n! Muon 0.5.0 - A teeny new feature, but I added a nice little busy indicator overlay on the changelog viewing tab while it fetches the changelog. This improves usability, so that you can tell when it is really working, etc. Try it out.

| Here’s a guideline for you: If your library uses exceptions, and you intend users of your library to catch them, don’t implement them inline in the header. Example:
class LIB_EXPORT MyException : public std::exception {
public:
explicit MyException( ... );
// ... (but no dtor)
};
Here, the compiler will generate a MyException destructor for you, since you didn’t provide one. Compiler-synthesised destructors are public, inline, have an empty body, and the same exception specification as the base class’ destructor. So, the above is equivalent to:
class LIB_EXPORT MyException : public std::exception {
public:
explicit MyException( ... );
~MyException() throw() {}
// ...
};
Unfortunately (well, actually fortunately, but not for our scenario), the destructor of std::exception is virtual, so ~MyException() throw() {} (explicitly written by you or synthesised by the compiler) is the definition (as opposed to declaration) of the first virtual function of the class MyException. Most C++ compilers take that as a cue to emit the MyException virtual function table, as well as its RTTI information at that point. Oops. Does ...read more...

So for the last months we have been working really hard to, port our great PIM software to the mobile world, and I must say it is a challenge, the rules all change and most of what you know does not fit the specificities of the interaction methods, the size and dpi of the screens, or even how something as simple as a gradient does not work as you expect.
Had that, to learning new exiting technologies like QML and starting to do working mock-ups with them that developers can interpret much better, and in some cases implement directly. (ok this was only a problem for me, but hey if I can do it any one can :) )
And wen you try do a no compromise, solution for the software, meaning that no major feature is removed, you find your self with a monumental challenge.
The good part is that so far we managed to overcome all major problems with what I believe in some cases are really innovative, new interaction paradigms, example the folder selection ...read more...

| Hey everyone, as the pencils down for this years GSOC is approaching I thought it’s time to write another blog entry to notify the world about my current status. These past weeks (boy, the time flies…) I’ve mostly spent on hardcore KDevplatform internals. Especially getting multiple languages in a single document working was not easy. I knew it would be the most time consuming and most demanding aspect during these three months, but also by far the most important. I’m confident to say now: I’m nearly there. All projects we put into the KDevelop repository have now a multilang branch in their team clones. And if you look at e.g. the KDevplatform multilang branch or the Quanta multilang branch you hopefully agree that I didn’t slack off too much. I just wasted some time to find the right approach, often by implementing one just to find out it was not practicable. Thanks (once again) to the help of David Nolden I’m now on the right track. Finally :) When you use ...read more...

As I mentioned in two earlier blogs now, within openSUSE a strategic discussion is going on - what direction should we, as a distribution community, take?
I would like to address a few things in this post. First of all, why a strategy, and what will it and won't it do? Second, there is one strategy I'd like to mention specifically, as I think it's disrupting but as a community proposal it deserves to be discussed as any other strategy. That's about the KDE strategy for openSUSE.
Strategy
But first about the idea of a strategy in the first place. The strategy portal page talks about it plenty and I won't repeat that. I only want to stress what a strategy does and doesn't do.
It does:- help make project wide decisions; for example say we choose the home for developers proposal and the liveCD is full. Do we remove the second media player or the second debug tool? The first it is...

In the mean time if you need to get in touch with me, hit me up on Twitter @nixternal, or if you have my phone number you can call me there. When I come back, I have a great review in the pipeline of a new ZaReason laptop that runs Kubuntu out of the box! My daughter and I have been having a blast these past couple of weeks. We have enjoyed the weather, watched a lot of bike racing, and she got groovy with Ubuntu. She likes Kubuntu’s look better, but I hooked her up with some Ubuntu to play around with. She wasn’t down with the default look, so we found some themes, colors, and fonts, that she likes, and thus far she has been happy. I need more than an ...read more...

...and the winner is...Berlin. It will be the "star of our system" for a week during the summer of 2011.
The II Desktop Summit has location, a good one. I'm excited about this event for several reasons. The first one is because, somehow, it gives credit to all the hard work done to celebrate the I Desktop Summit (Gran Canaria Desktop Summit). But above that, I'm excited because, after breaking the ice during that first approach, this event can be a huge oportunity to takes steps forward in joining efforts between GNOME and KDE to develop better technologies, better solutions for more devices and more exciting applications.
Beside pure technical issues, there is a lot of work we can do together in areas like marketing/promotion, usability, internationalization, education, etc. This is a great chance to begin.
So, do you want to know why Software Libre makes a difference? Come and live it by getting involved in decisions that matter.

While going through openFATE (the feature tracking tool openSUSE uses), I bumped into one asking for "Present Windows" effect as mouse button shortcut. In essence, this user has one of those million-button-mouses, and wants to use them.
I've heard that tune before, and last time I checked, linux users were still out of luck. Now I never had any idea what to use these 'extra' buttons for, until I bumped into this request. Having a button to triger an expose-like effect: great idea. Sure, I go with my mouse to the top-left of my screen and I can see all my apps just fine.
Still, I have only 4 corners on my screen (yes, it is square, as most computer screens) and 3 are in use already (app launcher, close window and clock). So I'd love such flexibility...
Now I don't know where the limiting factor is right now - what is needed to make it possible to assign actions to mousebuttons other than the left, right and middle one? Anyone who knows? Anyone up ...read more...

Release Roadmaps The KDE/Telepathy project has gained a lot of momentum in the last few months, and many of the basic components we planned to build have started to take shape. As a result, it’s time to start thinking about getting some of that code out there for testing. So, we’re planning to make a preview release some time this autumn. This release will be installable on top of KDE Platform 4.5, and will be suitable for power-users and testers who don’t mind a bit of breakage. We haven’t got a date set yet, but you can track the progress towards this release by looking at the dependency tree of the release bug. Developer Sprints In order to get all the separate Telepathy components we’re writing nailed down and working nicely together, and to allow API and Nepomuk usage review, we’ll be having a developer sprint. It will take place from 17th-20th September in Cambridge, UK (venue kindly provided by Collabora). More information about this sprint can be seen on its wiki page. ...read more...
