Gokmen Goksel (gokmen): A new stuff with the power of plasma !

System & Utilities

I have just finished my talk at Camp KDE, Jamaica about “KDE and Distros” with great partnership of Marcus D. Hanwell (slide is here), I talked about Pardus Technologies and showed people our plasmoid for service-manager which works with our sub-system COMAR.

When great projects come together results comes great !

Service-manager

Also I have a great video while it is working .. All of these written in Python, PyQt4 and of course PyKDE4 ;) You can grab the source from here.

Chani Armitage (Chani): adventures in plasmaland, part 3

System & Utilities

it’s day… 2? now, and near the end of the presentations I got the urge to write code. so now I bet everyone else is in the ocean, but I just can’t tear myself away until I get a few more bits working. :) perhaps it’s a good thing the internet is being crap, or I’d end up on irc… although not being able to commit is a PITA, and will make it harder for me to show incremental code improvements. we need git.

anyways, I started a new plasmoid. I think I might rewrite the other one in C++ - it’s either that or write a bunch of bindings or write a dataengine. but this new one should be more suited to scripting. it’s something pete calls a “victory calendar”. the idea is that you have a list of tasks that you need to do every day (like studying a language or doing pushups), and every day you record whether you did a lot, a little or nothing for each task, and so long as you don’t ...read more...

Aaron Seigo (aseigo): education oriented desktop redux

System & Utilities A week or so ago I blogged about making Plasma components that are designed for classrooms and younger people. Since then, we've had some draft code dropped into playground, a good amount of information written on the wiki and some commitments made to testing the results in real world settings.

It is very heartwarming to see such immediate and voluminous response to a simple blog posting. I'll be taking these early results with me to Tokamak in a couple of weeks to discuss them with others there.

I hope we can get something ready for production use, even if it is something simple and basic but an improvement over the current situation, in 2009.

Input, both of the data gathering as well as the code writing variety, are still welcome, desired and needed.

Marco Martin (notmart): C'est magnifique

System & Utilities

This is a tiny plasmoid hacked on a boring sunday afternoon in about 20 mins, perhaps a too silly name but i think the effect is kinda fun :)

It's an on-screen magnifying glass with the difference from the usual ones that it doesn't actually grab the screen, but it just views the Plasma canvas (just another view on the scene, that is), that gives some peculiarities, shown in this video:

OGG version

All the windows are totally transparent to it, so while is useful to view/magnify just what there is on desktop it can give a quick access on it, when you need both your windows and stuff on desktop (think about a non-fullscreen dashboard, and then think about drag and drop between dolphin and folderview even when you have a maximized window :P)

And the more cute thing is due to the vector nature of the QGraphicsView, you see all the proper vector-based elements like the text to be smoothly scaled and still looking like text, not that usual pixelated/blurry mess that kinda hinders the ...read more...

Aaron Seigo (aseigo): living room rock stars

System & Utilities I have a small confession to make: I love playing Guitar Hero and Rock Band. We recently got Rock Band 2 for the household here, unfortunately the drums were defective. A quick visit to the support website followed by a fair amount of traipsing about their pages led to a form to fill out. A couple weeks later and a new set of drums showed up at the door. I didn't even send them my receipt to provide proof of purchase within the warranty period either, even though they said I'd have to. Odd. Still .. yay!

I very much understand why people love to play these games and why they sell so well: it's a way to participate with a very low barrier to entry with something that a lot of people enjoy a lot (music) wrapped up in a fairy tale story (the rock star dream). I think it's fascinating that these games are introducing people to entire bodies of music fr the first time, both old and new, driving popularity and sales for the artists. The ...read more...

Alexandra Leisse (troubalex): Going Camping

System & Utilities

When the alarm woke me up at 5 yesterday morning, I found it hard to believe that I would be spending most of the day on various planes and crossing several timezones. To be honest, it felt close to impossible to get out of bed. But I convinced myself at last and crawled down the ladder of my loft bed.

At 7.55 and -6° C Thomas and me got onto the plane to Heathrow. Surprisingly enough I didn’t have to hurry this time: I actually was early enough at the airport in Oslo to have a nice cup of coffee and call home.

Arriving at our gate in Heathrow, we met Leo who boarded the flight to Miami with us. I have never been on a plane for more than 4 hors before and I must say: it’s pretty boring. Especially when there is not much to see outside apart from clouds, water and empty icy Canada.

In Miami I had trouble finding my suitcase which could not be checked through to Montego Bay and going through customs took ages. ...read more...

Jos Poortvliet: Jamaica rocks...

System & Utilities Working on the articles there were a few things I didn't put in there.

And some things I did :D

Last night I'm sure the Plasma team had their weirdest location for discussing code - ever. The Caribean sea. Now I'm all for technical talk but that went a bit too far for me, Others however, on hearing there was a discussion about plasma going on, joined them. Aaah well. I've been drinking Jamaican Rum and beer, pretty good stuff.



The morning here was interesting, as many ppl had arrived late last night. I just heard Zack appologize for being Zack ("I'm sorry, I'm Zack"), there is a guy sitting next to me with a "One Laptop Velicoraptor per child" t-shirt and I'm sure there have never been so many laptops on this beach. The food is very good. I had a Jamaican breakfeast yesterday just like today, loved it despite having no idea what ...read more...

System & Utilities

wheeee! I got off the plane in jamaica, and felt the relaxed atmosphere at once. :) the customs line was horrendous, but I met up with some other gearheads there :) and after much delay we were off to the resort. I wasn’t expecting it to be such a long drive… we got to see some of jamaica before dozing off, though. it kinda looks like a clean non-asian version of china, to me. ;) oh, and we bought peanuts from one of the street vendors who run alongside the cars to sell their stuff.

the resort has a beautiful little sandy beach by the bar/restaurant, and the water is only a few yards away. lovely mild water (I won’t call it warm, but it’s not freezing), hardly any rocks or seaweed or driftwood or other annoyances that are everywhere in vancouver waters… there was a bonfire on the beach, and after dinner several of us ended up going out for a swim… god, looking up at the stars from the water on a warm night is just… ...read more...

Aaron Seigo (aseigo): Tokamak II

System & Utilities


"After the very successful first Tokamak in Milan, Italy we would like to repeat this at the second Plasma developer meeting in the beautiful city of Oporto, Portugal. The local ISEP institute, kindly offered to host this meeting. ISEP is very interested in Open Source technologies especially exiting and promising ones like KDE's Plasma. ISEP wants its students of computer science to experience Open Source Software creation and community." - From the Tokamak II planning page on Techbase


Tokamak II will be held on February 6th-9th and we currently expect 15 members of the Plasma team to attend, along with some local visitors on the first day. We'll be sure to keep you all informed via the blogosphere as to what goes down at this developer sprint. The focus will be on planning for 4.3 as well as a bit longer term, with an emphasis on integration social features into Plasma and generally extending the power of Plasma even further.

Richard Dale: Introducing Wt::Ruby, a Qt-like api for developing web applications

System & Utilities

Before going to last years Akademy I had planned to use the week to try and start helping out with Ruby support for KDevelop4. In the end I got sidetracked by two things; playing with the Nokia N810 and finding out about a web application development library called 'Wt'. Koen Deforche gave a talk about Wt and I was impressed the way he described how web development usually sucked, and why a widget based desktop style api was better than the usual web page with embedded code approach.

After the talk, Pau Garcia i Quiles introduced me to Koen and Wim Dumon who are the two main Wt developers. Pau has used QtRuby and Korundum a lot and so I know he likes Ruby, and yet he thinks the best web toolkit is Wt, which usually involves coding in C++. Hmm, WTF - there must be something interesting with this stuff I thought?

They helped my get Wt built using cmake and linking against the boost libs, and I had a go and running the Wt headers through the kalyptus ...read more...

Agustin Benito Bethencourt: GCDS'09 news

System & Utilities Both boards (GNOME and KDE) along with the local team keep working on the organization of the Gran Canaria Desktop Summit:GUADEC + Akademy 2009. After the visit of representatives from both staffs to Gran Canaria, last december, we will celebrate another meeting during FOSDEM. In a few weeks an open mailing list and a community tool (a wiki or something like that) will be configurated so people can help us to make something special out of this event.

The local team has a strong recommendation: buy the tickets as soon as possible. A parallel program for families will be offered so don't be afraid of bringing them with you (little kids included).

Stay tuned for news and recommendations through the website of the event or by reading the twitter account we have for minor announces: gcds_2009.

Please, spread this recommendation.

Michael Leupold (lemma): Bugzilla->{speed}++;

System & Utilities

During the last week I've been working hard on the Bugzilla sources (I've even been learning some Perl :-)) trying to make searchers faster. It made a rather lengthy blogpost (containing some big pictures though) and I wasn't sure if the general Planet KDE audience was that much interested in it as it's only partly related to KDE. So to avoid spamming the Planet all over I decided to make it a separate post which doesn't get syndicated. It might be interesting to you if you're into Bugzilla, full-text search or semi-fancy benchmarking graphs.

Aaron Seigo (aseigo): what do you get when you remove 128 lines of code?

System & Utilities Shawn Starr was probably the first person to actually start writing a sophisticated DataEngine for plasma: WeatherEngine. He started working on it before 4.0.0 was released even. Yes, he is a mad man, but thanks to his brash insanity Plasma::DataEngine got the crud kicked out of it. It was also where we first found the need for Plasma::Services.

Still, thing weren't perfect. The WeatherEngine uses DataEngines itself and chains them together. So when you ask for weather for a given location, WeatherEngine actually loads a second DataEngine that talks to that specific service. This makes each service nicely compartmentalized and plugin based without a whole lot of duplication of effort.

Chaining the DataEngines was not exactly a straight-forward exercise back then, but Shawn muddled through and the DataEngine API improved alongside those efforts. It did, however, work.

Today on IRC while discussing things like being able to easily add new WeatherEngine plugins, I realized that by using DataEngine for the plugins we should also be able to get scripting and package support ... for free!

Well, ...read more...

System & Utilities First of all, greetings from the beautiful country of Jamaica!!! I'm here to help prepare Camp KDE, and as such, enjoying good company and great weather...

Yeah, about that company. I'm amazed by Jamaican hospitality. For me, dutch, being rather crude & simple folks, it makes me feel uncomfortable. My host gave me his bed, and made me breakfeast. Even cut the fruit in pieces - last person who did that whas my mom, and that was a long time ago. Hmmm. When I have a friend over, I trow a matress on the floor and tell him where the kitchen is...

Frank Karlitschek (karli): openDesktop.org experiments with marketplace

System & Utilities We started an interesting experiment. From today applications, artwork or document templates can be uploaded to openDesktop.org, KDE-Look.org and KDE-Apps.org for free downloading as before. But starting today, you may also select to sell them to users on the Marketplace of openDesktop.org. We try to do this in a way which is in line with the free software spirit

The Marketplace/App Store on OpenDesktop.org does not take a commission on sales. So 100% goes directly to the developer. It also doesn't dictate which applications, artwork and documents may be listed. Instead, all applications and artwork are welcomed, including binaries of free software, icon designs, wallpapers and document templates. This is new for the free software world. 

Free software for money? 
Is it fine to sell free software? Isn

Ariya Hidayat: capture the idea, before it is long gone

System & Utilities

Using WebKit, it is quite trivial to create a tool that grabs the contents of a web page and then saves everything as an image. Together with the new full page zoom feature, we can have the zoomed in or zoomed out version of the page, even at different viewport sizes (which may simulate different screen resolutions). In fact, that is what I describe in Qt Labs on the topic of Capturing web pages.

Just imagine you can have that small utility and you can run something like (web address, zoom factor in percent, output filename, optionally also the viewport width): webcapture www.trolltech.com 50 trolltech.png

what would you do then?

Aaron Seigo (aseigo): building a community around your F/OSS project

System & Utilities Today has turned into another writing day for me. Huzzah! I started going through my list of blog-posts-I've-not-yet-written and decided to punctuate the day with a couple of them. So let's talk a bit about building a community around your F/OSS project.

Usual disclaimers apply: this is what works for me, it may not work for you; I could be completely insane and talking about my posterior; I probably am just repeating what other people have said elsewhere; I'm going to be hypocritical in places by giving advice that I don't follow overly well myself. So there.

Onwards!

Why It Matters



It is not uncommon to read about projects that are suffering from lack of development resources. Let's be honest: no project has "enough" people, ever. There's always something else that could be getting done "if only we had another pair of hands!" Some projects suffer more than others, however.

Recently, one of the OpenOffice.org developers opined about the demise of developer contributions, a KStars developer sent out a small S.O.S. on their blog on ...read more...

Casey Link (ramblurr): A Quickie: Amarok, Last.fm, CampKDE

System & Utilities

Things have been busy around here! First, there was the end-of-semester rush that occurs right before exams, then there was exams themselves. After the 3-day cross country drive home, I’ve spent the last couple weeks playing Settlers of Cataan with old friends, and hitting the ski slopes a couple times a week.

In between all that I haven’t had much time for development. Actually, I told a small lie. I’ve been pretty busy with a secret project ™, but I can’t post anything about that until the 19th.

Amarok wise, things are looking up. I’ve started to completely refactor the last.fm service in Amarok 2. Expect a more explanatory post (plus screenshots!) soon.

Finally, Camp KDE is a few short days away. During the conference Leo Franchi and I plan to knock out some huge improvmeents to Amarok 2’s Context View.

Gah, Gah, Go, that’s all folks!

Im Going to Camp KDE!

Matt Williams: LGPL Qt 4.5.0

System & Utilities

I know I'm not the first to post about this (I'm about 12 hours too late for that) but I do think it's very exciting news. I can't see any immediate impact it will have on the KDE desktop itself but I'm sure that 6/12 months down the line, once Qt usage is increased and bugs are fixed and new features are implemented, we'll feel the impact.

It interesting too see how far this news has spread across the Internet too. For example I'm a regular on the Ogre3D forums and even though there's very little interaction between the two projects, there's discussion going on there.

Perhaps the most surprising thing, however, is that reading the Dot post about it there's probably the lowest level of trolling I've seen in a long time. Not even hardly any anti-GTK trolling either which is good to see. Well done community!

(On this note, does anyone know of any time line for the new Dot? I heard before 4.2 is released but that's getting closer now.)

Aaron Seigo (aseigo): KDE: Linux Format's Free Software Project of the Year

System & Utilities Linux Format recognizes stand out projects and members of the Free software world with their Reader Awards. The readers of the magazine send in their votes, Linux Format (LF) tallies them up and then publishes the results.

In the awards overview article, LF observes that "it takes a lot of planning, a lot of hard work, some serious code fu and, above all, a commitment to the ideals that underpin our movement."

How true. In recognition of the path KDE took in 2008 from the initial 4.0 release through to our current effort, the readers voted overwhelming for KDE as the Free Software Project of the Year. This wasn't a desktop only category, it could have been any Free software project. To all the users who voted: thank you! To everyone contributing to KDE in any of the many ways possible (coding, translating, usability, artwork, community guidance, marketing, biz dev ...), a huge congratulations and thank you to you as well.

1) Mapping between global coordinates and scene/item coordinates.

QWidget can map its local coordinates to and from global (desktop) coordinates. This is useful for positioning popups or other windows relative to the widget (since window positions are always defined in global coordinates). It’s also useful for ensuring that something is close to the mouse cursor. There’s basically many use cases for global coordinates, and mapping to and from them. For some event handlers, Qt does this for you automatically, such as QWidget::mousePressEvent().


void Widget::mousePressEvent(QMouseEvent *event)
{
QMenu menu;
menu.add…
menu.add…
menu.add…
menu.exec(mapToGlobal(event->pos()));
// or simply menu.exec(event->globalPos());
}

Now the problem. One vanilla Qt widget can only appear in one spot, one desktop. In Graphics View, it can appear in several places (e.g., in the chip demo). This means QCursor::pos() can mean different ...read more...
