Michael Pyne (mpyne): GNOME + Slashdot

System & Utilities

So our brothers/sisters at the GNOME Project managed to hit the front page of Slashdot.

There’s a lot one could say about the topic, but I’ll just leave it at this: I think it’s ironic that a project started essentially entirely due to the non-Free nature of Qt (at that time) would decide to separate from the Free Software Foundation and GNU based on Richard Stallman’s disapproval of proprietary software. I guess the times, they are a-changin’.

Peter Penz: Version Control Support

System & Utilities Before a feature is added in Dolphin, it is checked whether the feature is mandatory for Dolphin’s target user group. If this is not the case, it does not mean that the feature cannot be added; first it must be clarified whether the feature might be non-intrusive and adds a value for users outside the primary target user group. Non-intrusive is mainly related to the user interface. A feature that adds a lot of clutter to the main menu, context menus or toolbar might harm the target user group. In this case the feature will not be added.

A good example of a feature that is non-intrusive is the embedded terminal in Dolphin. It only requires one entry inside a sub menu, but adds great value for a lot of people that are not in the scope of Dolphin’s target user group.

Another kind of non-intrusive feature will be available for Dolphin in KDE SC 4.4: version control support. In KDE 4.4 at least a plugin for Subversion is given:

Boudewijn Rempt (boud): Wow!

System & Utilities

Thanks to our latest donor, Silvio Grosso, we're at four thousand euros now on Pledgie: Help raise Krita to the next level -- which together with the donations people have made into my bank account directly, means that, even after Paypal has taken its cut, Lukas will be able to work on Krita for another month in the summer!

Here's a screenshot of Krita showing off a feature Silvio asked for that we never really highlighted before: using flake shapes, it's easy to add vector arrows to screenshots, to point out important items. In this case, the default color setting for a new image, which is what I'm working on currently:

Deep-felt thanks go to the more than 160 people who cared enough about Krita that they made this donation drive such an unbelievable success! It is a big vote of confidence and I am determined that we'll prove ourselves worth of it.

Thiago Macieira (thiago): Incremental improvements

System & Utilities

I don’t know if this is showing up for the community, but we in Qt have been dedicating a lot of effort for performance improvements in Qt. For Qt 4.5, we had a project codenamed “Falcon” whose job was to improve the graphics engines and make them perform much faster. From that project, we got the graphics engines, including the raster and OpenGL ones.

For Qt 4.6, there was a lot of work done on Graphics View. For Qt 4.7, we’re going to do some more. Where, I don’t know yet.

Among the many ideas, one I’m interested in seems very small, but may be of important benefit: removing volatile from QAtomicInt and QAtomicPointer.

Here’s what happens: QAtomicInt derives from the internal class QBasicAtomicInt, which is a struct of one member: a volatile int _q_value. Similarly, QAtomicPointer derives from QBasicAtomicPointer, which is a struct of one member: T * volatile _q_value. The idea here is to remove those two “volatile” keywords.

Before you cry foul and tell me that I’m going to break your ...read more...

Mario Fux (unormal): KDE multimedia sprint 2010 in Switzerland

System & Utilities

As I already shortly talked about in my last blog (btw: Jara is not with me anymore but that’s another story) there will be another KDE sprint in Randa, Switzerland. The date will be during May 2010 (the exact dates will follow next week) and the place at the House Randa.

If you have any relation to multimedia in KDE (audio, video, players, metadata, ideas or proposals) please add yourself to the doodle survey (your name together with your project). Especially if you are a Nokia/Qt person and have any relation with Phonon or Qt Multimedia please add yourself asap.

Until now the following projects are informed about the doodle survey:

Bertjan Broeksema: All good things come to an end....

System & Utilities

even so KPilot. After having been part of KDEPIM for years it has been moved to tags/unmaintained/4/kpilot today. For months now no real development happened, there was not even bug fixing. I guess we have to draw our conclusions from that. Jason already said he lost his interest after buying a new phone about a year ago, while I myself still do have a palm I actually don't use it anymore.

KPilot has been a fun ride for me. Adriaan de Groot once dragged me in when I requested a new feature. It where my first in KDE software development. It showed me the trickeries of syncing pim data between two devices and it got me in touch with Akonadi. I even think it was one of the first pim applications to make use of Akonadi.

So this means that from KDE SC 4.4 on users won't be able anymore to sync there palm with the PIM suite again. I'm sorry for the inconvenience for those who still did (I did see a bug report coming up every now and ...read more...

Celeste Paul (seele): HCI Foundations: Web Interfaces

System & Utilities

This semester I have a class which examines foundational literature in Human Computer Interaction (HCI). Each week we have a topic and have been asked to write a short response or position on a question related to the topic. These responses could be interesting to those who are interested in HCI or would like to know more about the real science behind usability and design. I’ve decided to share some of my responses here on my blog.

Question: What are design issues in developing web user interfaces?

Keywords: AJAX, rich information application, usability, user interface, web development

AJAX (Asynchronous Javascript and XML) (Garrett, 2005) is a relatively new web technology which allows the browser to make server calls and display new data on the page without having to refresh or “repaint” the page. The technology has been at the forefront of what some call Web 2.0, a host of web technologies and services which is often characterized by features such as improved interactivity (because of AJAX technology), user-generated content (such as wikis), and social networking services (such as Facebook).

Michael Pyne (mpyne): kdesvn-build konversation

System & Utilities

Now Konversation has also switched to git.

Peter mentioned it being unfortunate that there was not a way to build Subversion and git modules with the same tool. Except that there is, and has been since October (and even before in the summer if you like unreleased code). kdesvn-build. Yes, I know I still need to rename it, I’ll get to that eventually ;)

Anyways, here’s what I added to my existing kdesvn-buildrc to build konversation:

module konversation
repository git://gitorious.org/konversation/konversation.git
branch master
end module

Now one catch is that scripts (including Michael Jansen’s build tool, last I’d heard) seem to have less success running git than doing so at the command line :-(. If you do end up manually cloning the git repository then make sure you’re using the trunk version of kdesvn-build to avoid git errors later.

One possible workaround is to use the HTTP protocol for the repository instead of the git:// version, but that’s less efficient so I’d really prefer to ...read more...

Michael Jansen: Build-Tool 0.1.4 released

System & Utilities

Adjust the recipe to konversations move to git. No other changes.

If you installed build-tool as a gem just issue sudo gem update build-tool.

The tool does not migrate automatically. To migrate delete ( or move ) the previous konversation checkout, then rebuild konversation with kde-build build -u --from-scratch network/konversation.

Ruby 1.8 required

Build-tool requires ruby 1.8 for now. When i started it ruby 1.9 was still seen unfit for production use and noone was able to estimate how long it would be that way. It doesn't work with 1.9 currently and as long as opensuse doesn't provide a 1.9 package it will stay that way.

Peter Simonsson (psn): Konversation has switched to Git

System & Utilities

As many of you probably already know, KDE has its eyes set on moving to Git, the revision control system developed by the Linux kernel developers in 2005 (and now in use at a great many places). Everyone's favorite music player Amarok already made the switch in July of this year, and today Konversation has followed suit! The nitty-gritty follows, Q&A style:


Why Git?

Most Konversation developers have used Git for some time already, either on other projects or even for their Konversation work (via git-svn), and have developed a strong preference for it, especially due to the superior performance and the way it greatly improves the local workflow by adding powerful branching and merging features over a Subversion working copy. We're also looking forward to sharing in some of the benefits reported by the Amarok developers after using it for some time.

Another advantage of Gitorious specifically is a lowered barrier to entry for external contributors, thanks to the possibility of making personal ...read more...

Justin Kirby (neomantra): What’s going on in KDE promo land

System & Utilities

Just wanted to provide a few quick notices/updates to the community on some promo activities.  I know everyone is busy with the upcoming holidays and the 4.4 release on the way so let’s cut to the chase:

  • KDE apparel design help wanted! – The promo team is in the process of trying to build up some awesome new KDE gear for you all to wear.  We have an online store  that we’re setting up and would like some help from any interested design gurus out there that think they could make a cool looking t-shirt, hat, etc.  Email me (justin at neomantra DOT org) or the KDE-Promo mailing list or leave a comment…find some way to tell me how I can reach you and I’ll get you details on how to get started.

Guillaume DE BURE (gdebure): More usability feedback needed

System & Utilities Since I got many interesting comments on my last blog on Skrooge usability, I figured out I could once again request your valuable help, dear users, on one of the most difficult part... Let me introduce to you the current "Search and Process" interface :


The goal of this is to find a set of operations and apply them a transformation. Example:
Find all imported operations with Comment containing Acme, and set their Category to Clothes
Pretty useful huh ? I can safely say so, because it was not my idea, but Stephane's* ;)

Anyway, the current interface is, in my opinion, far from optimal, so I've been trying to make some proposals. The first one is for the search section:

Marcus Hanwell (cryos): Big Snow!

System & Utilities

As some of you may remember we moved up to Clifton Park, NY in September. From when I first met Bill at Camp KDE in January he told me about all the snow they got up here. To be honest I was starting to doubt him, and then we got some snow on the weekend and I was really excited. Today I woke up, looked out and saw we got a lot of snow! I am not disappointed, possibly a little overwhelmed...

Snow, lots and lots of snow!

I think I am going to like it up here, Dax loves it and William is not too sure what to make of it right now. They just plowed the road (not our big drive though), and so I may try to venture into work soon. Of course Dax and I had a big play in the snow, and I think we are going to have to buy a sledge as soon as possible.

Winter is here, the snow is falling, the frost is crisp each morning and it get progressively harder to break the ice for the day's canoe.

Fortunately Kubuntu has just the thing to keep you snug in these cold months. From the davmor2 knitware shop comes the Kubuntu jumper range. Available in a selection of colours including beige with blue, beige with ligher blue and beige with cyan, it has been carefully crafted by designer extraordinaire Sue Morley over many months of hard work. Order one now, it's the perfect fashion item to impress that special someone in your life for Christmas (possible 6 months waiting time from ordering).

Hugs to Sue for being the best knitter I know.

Stuart Jarvis: The wow factor

System & Utilities
Wow, by Robin Gallacher (CC-by)

Wow, by Robin Gallacher (CC-by)

How do we get more people interested in KDE software? We can talk about it being Free (and free), point out that it does everything that the proprietary competition can do (if that’s true) but there is always a cost in changing software: you have to learn new stuff. Therefore our biggest openings are when the alternatives suck and so people are looking for change or when our stuff just leaves the competition for dead. The latter one is about the wow factor – something in our software that makes the casual observer sit up and take notice and think “I want that”.

The wow factor could be visual, but it needn’t be. Here are a few things that have prompted people who see me using KDE software to ask what the application is:

  • KWin – the desktop effects are really pretty slick now (this one works best on people who ...read more...

Richard Dale: JSmoke bindings KDE hello world working

System & Utilities

The Smoke based QtScript bindings are progressing well, and are now called 'JSmoke' in the style of 'JQuery' the JavaScript library or 'JScript' the .NET JavaScript implementation. In KDE promo-like words, I hope this will 'raise the brand recognition' of the state of the art KDE Smoke dynamic language bindings technology.

The project now has 24 QtScript plugins for the following libraries:


qtcore
qtdbus
qtgui
qtmultimedia
qtnetwork
qtopengl
qtsql
qtsvg
qtuitools
qtwebkit
qtxml
qtxmlpatterns
kdecore
kdeui
kfile
khtml
kio
knewstuff2
knewstuff3
kparts
ktexteditor
kutils
plasma
solid

There is a common 'libjsmokeruntime' lib that the plugins share. For running scripts there are two executables 'jsmokeapp' and 'jsmokecoreapp' for GUI and command line apps respectively. 'jsmokeapp' loads the qtcore and qtgui plugins and starts a QApplication. There still needs to be a 'jsmokekapp' which will start a KApplication, load the base KDE plugins, and run a KDE based script. Today I got a half Qt/half KDE app working. Here is the code:

qs.script.importExtension("jsmoke.kdecore");
qs.script.importExtension("jsmoke.kdeui");
qs.script.importExtension("jsmoke.kio");

function MainWindow(name) {
    KMainWindow.call(this, name);

Jos Poortvliet: Who is KDE? (continued)

System & Utilities In my previous blog I talked about who KDE is and how the web is full of cool blogs and podcasts and more about our community. In this blog a few more links ;-)

Check out the Blue Mint blog. Darn. This one is way cool for sure. The blogger (James Cain) aims to help and inform Linux Mint KDE users about their favorite desktop software. He started only 6 weeks ago but is very productive. Imho this blog would fit nicely on planet KDE, he might not be a developer but writes excellent and informative blogs. Or should we create a KDE user planet?

Here's jmiahman, blogging since april 2009. Clearly a Mandriva user, he recently wrote a nice review of the development version of KDE SC 4.4. Regularly blogs about other KDE stuff too, his latest one (as of this writing) is about amarok.

Mark Kretschmann (markey): ColdStorage - A Backup Tool Using Git At Its Core

System & Utilities Short article about a new project we started:

ColdStorage


What is ColdStorage? Well, basically it used to be a Vaporware project, started about two weeks ago, which is now no longer Vaporware. It started out with some of us KDE folks getting fed up with existing solutions for using Git as a backup tool (for backing up $HOME, etc). There are a number of existing projects that try to do the same, but I found none of them working, either not working at all, or not fully working.

So we thought, hey, let's give it a try by doing it ourselves. What we started with was a basic idea, a cool name, a Git repository, an IRC channel (#coldstorage on Freenode), two developers, and a bunch of code stubs. Thanks to Thomas Zander, we now actually have some code. Thomas managed to create some initial code for it basically on a Sunday evening.

Now, the project is ...read more...

Aaron Seigo (aseigo): netbooking it

System & Utilities It's been another insane week of activity for me, but fortunately it's also meant having a lot to show for it. As one example, we put the Plasma animation hooks through one more API review and we're pretty happy with the shape of it now. I have some work to do in the JavaScript Plasmoid engine to reflect some of these changes, and that's a good example of how activity often causes even more work for us. ;)

Today, however, I'm in Paris attending the Netbook World Summit. I'll be taking part in a panel presentation this afternoon, but the most important thing for KDE here is the human networking opportunities. I've been joined by Frank Karlitschek to represent KDE here, and it's great to have an extra pair of hands, ears and eyes so we can get the most out of this event.

Adriaan de Groot (adridg): Tribulations of a packager (3)

System & Utilities

I’m writing these lines from inside Konqueror 4.3.80 on OpenSolaris. I wrote previously that Konq is much better with Wordpress nowadays, so that means I can blog from a browser I like under an OS that I like (or I could boot into FreeBSD and do the same thing thanks to the efforts of miwi and the gang). It was Sinterklaas this weekend, and the ole Sint brought the kids too many toys and brought me updates to the spec files for KDE software on OSOL.

Ben Taylor has picked up the prodigious (or is it Sysiphean?) task of updating the dependency tree for Solaris 10 again.

Elsewhere in the stack, strigi was updated to 0.7.0 (thanks Jos for having an official release available), shared-desktop-ontologies was added at version 0.2 (a simple build), soprano was massaged once, then virtuoso added for version 3.52.7, then soprano massaged again, then cursed, then discarded. Then all the staightforward stuff involved in updating libs, pimlibs, base-* — that is basically updating packing lists to reflect new or changed files and removing the patches ...read more...

Alvaro Soliverez (Hei_Ku): What makes a killer app?

System & Utilities

It was recently brought to our attention this thread on forums of PC Linux. It was started by a long time user of KMyMoney, so it's no wonder that he mentioned KMyMoney as a killer app. Several others mention KMail, Konqueror, Dolphin, et al.

We feel very flattered by all those mentioning KMyMoney, and at the same time it puts pressure to double the effort on the KDE4 port. Anyway, it got me thinking into what makes a killer app.

Cornelius Schumacher: Build openSUSE 11.2 appliances in SUSE Studio

System & Utilities We released support to build openSUSE 11.2 appliances in SUSE Studio today. It took a bit of time to sort out all issues and do proper QA, but now it should work fine. If you find remaining problems please let us know.


Many of you will want to migrate existing appliances using an older version of openSUSE to 11.2. In many cases it's probably not a lot of work to recreate the appliance from scratch with openSUSE 11.2 as a new base, but that's clearly not a good solution for all cases. So we are working on a way to automatically migrate appliances to a newer base system. We'll let you know when it's done.

And now for something completely different: It's snowing in SUSE Studio land.

Sebastian Trueg (trueg): Convenient Querying in libnepomuk

System & Utilities

It has been a while since I blogged and a lot has happened. Not only did we have the second Nepomuk workshop on the “Open Social Semantic Desktop” which I did not report on yet, there is also a lot of stuff going on for KDE 4.4. And since I like blogging about technical stuff so much I will start with that. So here goes:

Queries in KDE 4.4 will be so much simpler (for the developer that is) since we now have the Nepomuk Query API!

Do you remember the days when you tried to write your own SPARQL queries and code looked like this:


Nepomuk::Tag myTag = getOurFancyTag();
QString query
= QString("select distinct ?r where { ?r %1 %2 . }")
.arg( Soprano::Node::resourceToN3(Soprano::Vocabulary::NAO::hasTag()) )
.arg( Soprano::Node::resourceToN3(myTag.resourceUri()) );

Well, using the query API this looks a lot nicer:


Nepomuk::Query::ResourceTerm tagTerm(myTag);
Nepomuk::Query::ComparisonTerm term(Soprano::Vocabulary::NAO::hasTag(), tagTerm);
Nepomuk::Query::Query query(term);
QString queryString = query.toSparqlString();

As you can see you do not need to know any SPARQL anymore. But it gets better. The ...read more...

Jesper Thomschutz: GCDS - the story so far

System & Utilities

The Grand Canaria Desktop Summit has been incredible so far. The amount of talent and enthusiasm for Free Software has not only been amazing, but equally impressive and inspiring. The GNOME and KDE folks talking openly and discussing future plans - proving - that the so called "desktop flame war" is more or less completely gone. I really look forward to the hacking these coming days - hopefully implementing a few of the things that have been discussed this weekend myself. Also, worth mentioning is the amazing job that Nokia did with the sponsorship. The conference location is top notch - the events great - and the swag is all very useful. Good job!

And now, we have the obligatory photos...
