Milian Wolff (milianw): KDevelop Hack Sprint

System & Utilities

Huzza! The KDevelop Hack Sprint 09 is now official.

Thanks to the huge engagement of Alexander Dymo we will meet from the 19th to 26th April 2009. The meeting will take place at Alexander’s university, the national university of shipbuilding in Odessa, Ukraine. Thanks to the people there responsible for making this sprint possible by providing us with the premises, internet, power etc.

Since this is my very first Hack Sprint and considering that I only recently started contributing to KDE in general and KDevelop in particular I am very excited. The topics I will plan to hack on include (all related to PHP language support plugin):

  • add auto completion after require(_once) and include(_once), just like it works for #include in CPP
  • add auto completion of PHP statements (think echo, exit, require(_once, include(_once) etc. pp.)
  • add auto completion for build-in PHP keywords
  • fix auto completion of interfaces / classes after the keywords implements and extends (working on that right now)
  • fix KDevplatform and the Generic Plugin Manager ...read more...

Gustavo Boiko: Small Projects Collection

System & Utilities

Long time no post…

While doing some cleanup in my home folder, I found some few applications I have started but never finished. So I decided to put all of them online so that people can check and (maybe) use the code for something more productive than being forgotten in the middle of many other disorganized files.

The programs are very simple (don’t expect any Ooohhh application there) but as I had fun doing them I hope you enjoy.

Check them out!

Dmitry Suzdalev (dimsuz): Klipper updates

System & Utilities

Hello!

Recently I’ve added a few things to klipper and I thought some of you might be interested to know about them. As for me I’d like you to test this and to report me any bugs you might find :)

Basically I’ve added two things. First: now when you copy some file path to Klipper, it can automatically determine a list of apps that can handle this filetype. Here are some examples of action menus it will produce:

klipper menus

Klipper action menus

So, now user has no need to add a lot of custom actions for a basic file types :)

Second, i’ve added a dialog which allows you to edit action properties or to add a new action. It looks like this:

"Action Properties" dialog

This dialog pops up when you click on “Add Action” or ...read more...

Alexis Menard (Qt Software): Writing a game with the animation and the state machine API

System & Utilities

If you’ve checked out the Qt solution for the Animation API, then you’ve probably found the game called Sub-Attaq. This game was an idea I had when I started working on the Kinetic project. The idea came from a game I played 6-7 years ago but i don’t remember its name anymore. For those who don’t know, it’s a simple 2D game where you control a boat and you can drop bombs on submarines.

Anyway, the goal of this game was first to play with it, and at the end to get a high score rank for the office (competition is always good). Oops, I forgot the obvious reason : testing our API for animations. So I started writing a basic game but I was busy with 4.5.0… so I let this game as it was, just some basic game logic and couple of animations.

But some months ago, a new state machine framework popped in the Kinetic repository. I have to admit that Kent convinced me when he introduced me the framework and I had participated in some API ...read more...

Jonathan Thomas (JontheEchidna): Plasma Weather Wallpaper (Hello Planet KDE)

System & Utilities So after I implemented tooltip support in QuickLaunch I started to look around for some more Plasma related things to hack on. That's when I happened upon this, which is how I stumbled upon this

I thought to myself, "That would be really neat!" So a few days ago I made a simple wallpaper plugin that would paint a specified picture to the containment background. Once that was working I raided the weather plasmoid of its configuration code and choice parts of its backend and ported it to work in a Plasma Wallpaper plugin. The result? A Plasma Wallpaper plugin that changes the wallpaper depending on the weather at a set location is. To retrieve the weather it uses the weather dataengine introduced in KDE 4.2, as seen in the Weather plasmoid and the LCD Weather Station plasmoid. Dataengines for the win!

Code is available from trunk/playground/base/plasma/wallpapers/weather. It should build with KDE 4.2 and KDE 4.3. Here's a small build tutorial:

- svn co svn://anonsvn.kde.org/home/kde/trunk/playground/base/plasma/wallpapers/weather
- mkdir build

Wang Hoi (wkai): Portable Meta-Information again...

System & Utilities Portable meta-information has been discussed twice recently:
http://www.kdedevelopers.org/node/3923
http://zwabel.wordpress.com/2009/03/29/portable-meta-information/

I also have something to say that doesn't fit into one comment, so i post it :)
My thought is realistic:
1. Will nepomuk really be more usable with portable/distributed stored meta information.
I don't know much of nepomuk's server implementations, afaik it seems use a central database to index/store these informations, so i've a question to ask : when user move his file to another local folder, will the file's meta infomation get lost , updated later(next time to index) or updated instantly (use inotify )? The first result(lost) is totally un acceptable, the second is ok, but nepomuk's value/power will be limited, the third is good, just stick to central storage.

2. How to implement it.
someone has suggested to use side-car file, other suggested xattr.
There is a seems better way to implement it : file forks/resource forks (not process fork),

RE[3]: kde vs gnome, qt vs gtk

System & Utilities

Any discussion about GNOME vs. KDE is sure to end in tears. It's basically impossible to discuss which of these two Free desktop environments is better than the other, mostly because they cater to different types of people, with different needs and expectatotions.

Torsten Rahn (tackat): Marble - Get involved!

System & Utilities

We've recently extended our Marble Wiki to include more documentation about how you can participate in Marble development. Here are a few possible jobs for a start:

Find out here how you are able to take part in this.
  • For source code aficionados we have lots and lots of JuniorJobs for Marble. You can have a look at our How to become a Marble Developer page to find out how to tackle those.

Tomaz Canabrava (tomaz): … but live happly

System & Utilities

Today I’m annoucing a new KDE-users ( and also coders and documentation writers) group.

Since my university killed the OSS movement inside it 1 year ago, like a phoenix it’s comming from the ashes.

liveblue

In portuguese ‘blue’ has a completely different meaning from English, it means ‘Nice’ and ‘Cool’,

So, with no more round ups, I present you the new KDE-Users, Coders, Artists and Documentation Team from Bahia, Brazil, ‘Live Blue’.

Initially it has 9 members from more than one university, and 2 projects. Armina ( a code-visualization tool ) and Rocs ( that one day I will finish it… )

The logo was made by Alexandre Freitas,  ( xandolino at gmail.com ), and I encorage everyone to send him a ‘thanks’ and a ‘come on, and meet the artists team’, this is not his first job for kde-related stuff, but mostly I poke him to help me with graphics ;D

Cyao people, tomorrow is calling me to bed.

Aaron Seigo (aseigo): decision trees

System & Utilities

On Saying "No"



When someone sends in a patch that they feel should be applied, it's always a difficult decision when the patch really shouldn't go in. After all, someone has probably put a good amount of effort into it: they've thought about the problem, come to a conclusion, plunged into the source code, altered it, tested it (well, hopefully :), then sent the diff in to be reviewed and commented on by their peers.

So when a patch just doesn't make the grade .. what do you? I hate saying "No." It's a lot less fun than saying "Yes." because "Yes" makes the person right in front of you happy. Unfortunately, when you are looking after a project (and everyone involved with a project ought to be striving to do that) there is more than just the person in front of you. No matter how loud they are, no matter how much hyperbole they throw at you, no matter how right they think they are .. they are not the only concern.

James Ots: tiny.url Breaks My Security Model

System & Utilities Since using twitter, I've noticed a lot of people use services such as tiny.url or tr.im in order to shorten URLs. There's a problem with this though: I now have no idea what website I'm about to visit. If someone I trust has posted the link I'm reasonably likely to click on it, but for other people I tend to avoid these shortened links because I have no idea in advance what they are.

What is really needed is for the shortener service to show you what site you're about to visit first, so you can make a more informed decision about whether to visit the site or not. Hmm, maybe I should be sending this as a feature request to those sites instead of randomly blogging about it...

Aaron Seigo (aseigo): more plasma screencastiness

System & Utilities I recently purchased a small pasta machine. I don't really know what the proper term for it is. I hesitate to call it a "pasta maker" because you still have to the bulk of the work yourself: making the dough, turning the handle, moving the handle between the different rolling and cutting mechanisms, feeding the dough through, etc. It uses no electricity and attaches to the counter or table top with a little vice. This really appeals to my "no school like the old school" side.

It's amazing how a little bit of flour, an egg and a bit of water can, in 5-10 minutes time, produce enough pasta (and then some!) for four people. Add some sauce, toppings and settle in beside a main course or a salad and voila .. great meal. The taste and texture of the pasta is unachievable with dry pasta or even the "fresh" pasta I can get from the grocery stores here. So instead of pulling out some dry pasta from a box (which takes about 10 seconds), I'm spending a whole ...read more...

Michael Pyne (mpyne): some things

System & Utilities

Well I went and ported kfile_torrent to be a Strigi analyzer so that the .torrent info metadata is available in KDE 4 now. Unfortunately although KFileMetaInfo has apparently been ported to use Strigi no metadata shows up for me in Dolphin. Maybe it will when I enable Nepomuk perhaps, kind of unfortunate that a feature more or less from KDE 2 is still unavailable though :-/

In other news I’ve been trying to find a good reason to play the PS3 that our family got last fall. Most of the games I’ve tried so far have not warranted the annoying aspects of a super-whamodyne system.

For instance, the last game I tried was Uncharted: Drake’s Fortune, which was very well reviewed. But, I didn’t find it very entertaining.

Once the game came in the mail (from GameFly, since I refuse to end up with another $60 stinker), I tried it out. It told me it had a required update to install (for the PS3 itself). Awesome. So about 10-15 minutes later, I end ...read more...

Ivan Cukic (ivan): WebKit + D-Bus -> Instant Chrome-like browser for GNU/Linux

System & Utilities

Webbie

I was wondering how hard would it be to create a web-browser that is, like Google’s Chrome, separated in different processes for different tabs. You know, the whole “security problems and crashing are restrained to single tab” thing.

As it turned out, it is not all that difficult. Create the main window, start the WebKit (QWebView) in another program, then X-Embed the later in the former, and communicate via D-Bus. (I got the idea to do this from Embed Window plasmoid :) )

If the child crashes, only one tab is gone. If the main application crashes, tabs become independent windows.

I’m not sure whether I’ll continue to work on this, but if I find the time, you could see a Rekonq-based (http://rekonq.sourceforge.net/) browser that is similar to Chrome someday.

Andrew Stromme (astromme): Python Suspend Applet

System & Utilities

Yesterday Sebas blogged about his desire for a small plasmoid that would allow him to suspend his computer when the screen is locked.

Since I already wanted an excuse to play around with a Python plasmoid, I decided this would be a cool little applet to code. Turns out that there is a (pending) freedesktop.org interface to power management and PowerDevil implements the important parts of this.

I started out with the great Python+Plasma tutorial and the second one on using the Plasma::Widgets that we know and love from C++. Couple that with the python bindings for dbus, and you’ve got yourself a little applet that suspends your computer at the press of a button.

You can find the applet on kde-look, and it should be present in GHNS as well. (working on this point… for some reason it’s not showing up for me).

Sebastian Kuegler (sebas): Summer of Code and Social Desktop

System & Utilities I've been thinking about Google's Summer of Code program a bit, and since it's having its fifth birthday this year. I thought it would be about time to congratulate the people at the Open Source Programs Office in Mountain View, especially Leslie, Cat, Tiff, Erica and all the others who I had the pleasure to meet at various occasions. Good works, gals!

From a KDE point of view, it's nice to see after 5 years that this Summer of Code works. "Works" means that it does get us a lot of attraction from new talent. There are actually quite some people active within KDE on a regular basis that have found their way into KDE through the Summer of Code programme.
It's good to see how this is managed by the Google staff as well, they're not just throwing money at us, they're actually putting a lot of effort into SoC, and it provides real, tangible and sustainable benefit for Free Software projects. That's money spent well.

Well, it seems to be the season when Plasma developers are blogging again about their progress =)…so..here I go =)

The weeks befora Bossa Conference Sebas started helping me with Pastebin applet as we discussed during Tokamak: it was not as sexy as a plasmoid needs to be. So he just started (re)doing the UI bits and I tried to help him a little bit. We cleaned the code, changed the UI completely and now it’s much better!

New pastebin UI (left default view, right mouse hover view)

Default view (left), Mouse Hovering (right)

Now you can also put it on your panel and have something that looks nice (instead of just a sentence telling you to drop stuff in that region)..We also added tooltips showing the status of the applet.

Leonardo Sobral Cunha (lsobral): New (and last?) QtAnimationFramework Solution

System & Utilities

Following the good habit of release early, release often: here we have yet another qt solutions release: the QtAnimationFramework 2.2 (and since 2.1 it’s LGPL too o/)

It’s mainly a refinement of the previous version, after a round of API review and incorporating all the feedback we got internally and externally. One main modification was to rename QtAnimation to QtVariantAnimation (this was to scare most users away from using QtVariantAnimation directly, as this is an abstract class). Apart from that, we did some minor API modifications in QtVariantAnimation, QtAnimationGroup and QtSequentialAnimationGroup and several bugfixes.

This solution also includes the code to the AnimatedTiles example that was previously posted here, by Andreas.
