Aaron Seigo (aseigo): KTorrent + Plasma = Good Times

System & Utilities Face of Aaron Seigo (aseigo)I just found out today that KTorrent ships with a DataEngine and Plasmoid. (Yes, sometimes I'm a bit slow. ;) Now I can watch my torrents progress without having to keep popping up the KTorrent window. Nice!

This inspired me to do a little bit of hacking on the applet this evening. When the icon is clicked, it now pops up the KTorrent window and if you drop an entry from KTorrent to the desktop KTorrent plasmoid is created.

Since KTorrent already has drag and drop support internally, all I had to do to get plasmoid creation working was add one line to the plasma-applet-ktorrent.desktop file: X-Plasma-DropMimeTypes=application/x-ktorrent-drag-object. Extra nice!

It took 17 lines of code, however, to have the plasmoid set itself to the dropped plasmoid. There's obviously room for improvement there in the Plasma API. Possible improvements might include a way to get at the drop data as text (would have eliminated 4 lines) and a way to query an engine for a sorce based ...read more...

Danny Kukawka: Wacom USB TabletPCs: persistent by-id links

System & Utilities
Since the linuxwacom package supports TabletPCs with USB tablets we have the problem to find the correct devices under /dev/input/* for the xorg.conf settings. While the input device of the stylus was easy to find (/dev/input/by-id/usb-Tablet_ISD-V4-event-mouse) but strange named, the input device file for the touch device needed to be searched by the user since there was no persistent link under /dev/input/by-id/ that would allow to use the same link for all USB based Wacom TabletPCs.

Now I've found a way to change udev to set also a persistent by-id link for the touch device. I also change the naming of the link to the stylus device. With my patch you get now these links under /dev/input/by-id/ :
tux@linux:/ # ls /dev/input/by-id/
usb-Tablet_ISD-V4-event-stylus
usb-Tablet_ISD-V4-event-touch
usb-Tablet_ISD-V4-stylus
usb-Tablet_ISD-V4-touch
The input devices you needed for you xorg.conf are the *-event-* links.

If you use openSUSE you can get patched udev versions from my buildservice repo. I've patched also SaX2 to handle the new link names (packages see here). Note: ...read more...

Ivan Cukic: Lancelot 1.0 Final “In my own… idiom”

System & Utilities

… I’m afraid when I’m in this idiom, I sometimes get a bit, uh, sort of carried away.

~ Sir Lancelot, Monty Python and the Holy Grail


If you’ve been watching the SVN logs, you might have noticed the tagging of the Lancelot 1.0. And now it is official!

Lancelot 1.0
lancelot.fomentgroup.org

Introduction

Lancelot is an alternative menu, or application launcher interface, for KDE 4.x series. If Kickoff or KMenu don’t fit you, feel free to try it. Lancelot provides a quick access to the most used applications, to your devices, contacts etc. in a familiar yet refreshing way.

1.0 Release highlights

  • Optional no-click interface which allows you to navigate through the menu and perform any action in it without making a single click.
  • The layout of the menu adapts so that most used parts are always closer to the mouse cursor.
  • Advanced search capabilities. Thanks to KRunner integration, you can search not only your applications, but also contacts, bookmarks and many more (even a calculator is included).
  • You can ...read more...

Holger Freyther (zecke): Acid3, make QtWebKit catch up

System & Utilities
qtwebkit-acid3


The Mac, Windows and Gtk+ port get 100/100 and pixel perfection for the acid3 test for quite a while but the Qt port was stuck somewhere else. How can this happen? For QtWebKit we decided to use as much of Qt as possible. So instead of relying on ICU we used the Qt Unicode support, instead of relying on libxml2 we used the QXmlStreamReader, instead of doing font matching and font/glyph caching we solely rely on QFont and QTextLayout to do the job. One had to apply some minor fixes to the Qt version of classes such as XMLTokenizer or TextCodec, or integrate SVGFonts into the Qt port as well...

What is next? We will have to get the rendering to be pixel perfect as well and then can merge the changes chunk by chunk. I'm going to sleep now, enjoy the screenshot.

Wade Olson: What 300mil can and cannot buy

System & Utilities

I like Seinfeld.  Watch his re-runs all the time.  This does not necessarily mean that he may bias my opinions or anyone’s opinion on the merits of Vista.  Marketing has the odd concept of a testimonial.  “I’m famous and I use this deodorant.  You want to stay unfamous and lame and smelly?  Then keep using the deodorant you’re using.  Otherwise be like me and be awesome and smell awesome.”  Why this works is beyond me, but it does.  Apparently Sinbad was already busy.  Hint for MS:  Everyone who will fall in love with your Seinfeld commercials already uses your products and doesn’t need reinforcement.  The influential and desirable demographic is busy buying Apple hardware and then installing KDE on it.  They don’t care about 90’s comedians.

In the months before Vista launched, I pointed out their missteps in needless product complexity, reduction of compelling purchase reasons, unrealistic price points and confusing/misleading hardware capability programs.  Now they’re at it again.  Is it that MS doesn’t understand how to run as ...read more...

Wade Olson: Be careful of what you wish for

System & Utilities

Because I’m an Idiot ™, although I really liked the look of the Akademy shirts, I never actually bought one.  I was thinking about it the last day, but got tied up and then had to leave.  Of course, immediately after departing, I wanted one.  So I emailed Sebas and asked if he could pick me up a shirt.  And I’m glad that he got one for me, because it sounded like a simple 72 Step Process to figure out your actual size.

So I get home from work and I see a package sitting on my steps.  It has “USA” in the address and postage paid in euros.

Could it be?  How did Sebas send out a shirt so quickly when he was at a conference?  Looking closer, this actually looked like the packaging from the motherboard that I smuggled (still sitting on a pillow) through U.S. Customs for Sebas - this had to be from him.  I finally notice the return address.  And when I opened it ...read more...

Vyacheslav Tokarev (vtokarev): soc is over, khtml is not

System & Utilities

GSoC is over for quite a while now, but that was a great time and it really helps if you want to join any open source community like KDE.

So, several days ago I was having discussion about multi-pattern search algorithm with SadEagle that could be used with adblock filtering. And I like the topic of high-performant algorithm. The same day I was reading several articles on that, the next day I was hacking on modified Rabin-Karp’s algorithm. Then I tried several more approaches, like Aho-Corasick.

A bit of testing, debugging, profiling and voila: several days after you could see the commit with numbers in it “7.6x improvement”. And us usual for practice approach (especially, with relatively short strings) algorithm shouldn’t be too complex but I enjoyed my little research anyway.

Big thanks for SadEagle, cause he did great job with it too. As well as performance improvement you could see ad block is now more compatible with adblock plus. and it supports whitelisting too.

Aaron Seigo (aseigo): kwin ftw

System & Utilities Face of Aaron Seigo (aseigo)Since I'm a little obsessed these days with software design that is adaptive, flexible and sturdy, it was with interest I read Lubos "Seli" Lunak's recent blog where he said:

"KWin's design is still about the same like in KDE2.0, and, apparently, it still just works. I can't see a problem with not having been designed from the group up for compositing, something that nobody even thought about at that time, yet getting there when the time comes"


That is really impressive as imeans that the code has the property of being able to go the distance by being easily extended and reworked without having to toss the whole lot.

What was really great to read in that same blog entry was that Seli has optimized KWin's performance and that it should now generally be on par with Compiz. Very, very nice.

We should keep in mind, however, that this is only half the battle: the effects themselves also need to be ...read more...

Adriaan de Groot (adridg): Twenty five or six to four, FLA?

System & Utilities One of the things that was done at the KDE e.V. general assembly at Akademy was the acceptance of an FLA (Fiduciary License Agreement) for KDE code. The FSFE press release and the dot story complement each other. Other coverage includes Aaron's blog and Groklaw.

There is a little bit of confusion about the FLA out there, so I thought I would post a few clarifying comments:
  • A fiduciary license agreement is an agreement between you (usually a software developer with a copyrightable code contribution) and another party whom you trust . This other party is the fiduciary (from Latin fides, I imagine). If you don't trust the other party, then they are not fiduciary and you can skip the whole rest of the discussion. (See also fides, sed cui vide ).
  • The FSFE (Free Software Foundation Europe) wrote an FLA for itself with which Free Software contributors can assign the copyright in their works to the FSFE. That works if you trust the ...read more...

Lucas Murray (Zarin): New present windows layouts

System & Utilities

There are now three layouts modes that can be used in the KWin present windows desktop effect:

  • Regular grid - The old layout that displays windows next to each other on a grid,
  • Flexible grid - Similarly to the regular grid except each grid cell doesn't need to line up with the others, and
  • "Natural" - Absolutely no grid at all, each window is placed wherever it best fits. (The new default)

Also fixed a bug that prevented correct keyboard operation on multi-monitor systems.

Elsewhere in KWin

  • Present windows can (Kind of) be used as the Alt+Tab window switcher
  • Lots and lots of optimizations
  • Magic lamp effect now works correctly when the panel isn't on the bottom of the screen
  • More work on the desktop cube/sphere/cylinder effect
  • Right-to-left language window title fix
  • The panel no longer overlaps fullscreen windows that lose focus (Most people that use multi-monitors come across this way too often)

hackergochi

This past week I have found it hard to get anything done. my P.O.S. laptop has been powering off every 10-30 Minutes. I opened it up to see what the problem was and it seems a few thing have gone to the laptop heavens. I don’t know how the Power Button cable got into the CPU fan ( but I can guess ).

So I decided to buy my self a new laptop, I was gonna get a desktop but since I have a few engagements in the following months I will need something portable to work on.

I searched around for good Linux friendly laptops that *hopefully* wouldn’t need special drivers ( damn EEEPC :P ) I found a good one at Dell’s site and bought my self a custom XPS laptop.

Tom Albers: Mailody and Akonadi meet Nepomuk

System & Utilities

Isn't it great to have two Pilars of KDE in the subject? Anyway, this weekend I started working on Nepomuk. The end goals is simple, I want to tag my e-mails and have the possibility to enter a comment about them.

First step was trying to get some basic interaction with Nepomuk. They seem to change their API a lot, so it took some time and help from DanielW on #nepomuk-kde to get that working. Afer that I went looking for a widget that could be used for this.

I actually like the complete widget that Dolphin uses, but that's not available in KDE libs and I did not want to go throught the process of doing the move. Luckely Nepomuk provides a tiny widget which can be integrated easily and does not take to much space in Mailody. I've put it in a QDockWidget so people can put it at the bottom of the complete Mailody window if they need more space. It now looks like this:

Aaron Seigo (aseigo): weekend updates

System & Utilities Face of Aaron Seigo (aseigo)Thought I'd offer a few updates from the weekend, which I've taken pretty easily just because I can. =)

Applet Positioning on the Desktop

Ambroz has been working on a new QGraphicsLayout class for use in full screen containments that basically acts like an organized corral: when new widgets are added, it tries to find a place for them that doesn't overlap with other widgets and if you drag a widget out of the containment or screen by accident, it pulls it back in. It resolves several issues at once, such as being able to drag items out of the screen with the applet handle, size changes leaving widgets in outer space and being left with piles of widgets in one corner after double clicking a bunch of entries in the Add Widgets dialog.

This work was the result of a build of things on Ambroz' part. I first started noticing his patches in bugzilla, but soon he was on the Plasma list and got his ...read more...

Richard Johnson: Docunification

System & Utilities

As a member of both the Ubuntu Documentation Project and the KDE Documentation Project, one thing is clear, our current state of system help isn’t the greatest. An initiative that the GNOME project has looked at taking on (for the greater part of the past 3 years) is called Project Mallard. There are some things in this project that I like and dislike, however one thing is clear, they understand the inefficiency of their current system and know it needs to be fixed. KDE is realizing this same exact thing and know we need to fix it, but figuring out how to do so correctly, isn’t the easiest thing.

One thing that GNOME, KDE, and others have worked hard to do is collaborate with Freedesktop.org specifications on many levels. Maybe it is time we look at continuing this excellence, but this time add documentation to the menu. How many of you GNOME users love using Amarok or another KDE application, but hate the fact that KHelpCenter is installed just so you can view the ...read more...

Simon Edwards: Development version 1.1 of Guidedog is available

System & Utilities

Just a small announcement. Development version 1.1 of my little network routing configuration utility is up on my website for your testing pleasure. There is no new functionality. I've just ported it from KDE 3 and C++ to KDE4 and Python, saving it from ravages of bit-rot. It's a neat little utility and it would be a shame to let it get lost on the migration to KDE 4. It is also in Python now which should make the code a lot more accessible for contributors. If you've written a few shell scripts in the past, then your skills a probably high enough to hack on Guidedog and fix any bugs which show up.

My attention is spread across too many projects these days which slows down fixes and applying patches. So I've now put the guidedog source in KDE's subversion repository in the playground/network section. (/trunk/playground/network/guidedog/) This will hopefully take me out of the critical path for fixes and patches.

I've also got a mostly done port of Guarddog to KDE 4 and ...read more...

Fred Emmott (fred87): mprisshell

System & Utilities Face of Fred Emmott (fred87)

I've written a small bash CLI interface to MPRIS players, available at http://files.fredemmott.co.uk/mprisshell.sh.

It's currently rather limited in functionality:


Usage: mprisshell.sh [command]
Commands:
play Start playing the current track
pause Pause the current track
playpause If a track is playing, pause it; otherwise, play the current track
next Skip to the next track
previous Skip to the previous track
incVolume [percentage] Increase the volume by 10%, or the given percentage
decVolume [percentage] Decrease the volume by 10%, or the given percentage

It sends the above commands to the first MPRIS-capable player found; this includes the latest git head of YANIHP, Amarok 2, Audacious, and others. It's meant for normal users, not developers, for example as a program to bind to media keys.

System & Utilities Face of Jonathan Riddell (riddell)

Akademy finished, it was great.

Next week is feature freeze in Ubuntu land, so we are working hard on filling the distros with the necessary features, if not always beastie-free.

We got a new Adept in thanks to the excellent mornfall, so now people can install and upgrade and manage their packages again. Some bits were missing though so I implemented an equivalent of adept_batch for installing packages from a command line with a GUI (used by Amarok's codec installer for example).

I also implemented a notifier to tell you when there are updates

This includes a feature called upgrade hooks used when package updates have actions which should happen after the update.

It also keeps an eye on Apport, the Ubuntu crash handler. Today I turned off drkonqi in KDE apps in favour of Apport as an experiment with our Bugs team to see if they can handle forwarding bugs upstream as necessary. ...read more...
