Stefan Majewsky (majewsky): Palapeli: Visual changelog for today

System & Utilities

Nothing happened in Palapeli land since the 1.0 release together with KDE SC 4.4. The wishlist was slowly growing, but today I’ve started to implement some smaller items on the todolist. The big ones (GHNS integration, puzzle piles and rotateable pieces) are still left, but now I present you the first new features that will appear in Palapeli 1.1 (KDE SC 4.5):

This screenshot shows two closed wishlist items: Instead of a background texture, one can now also select a solid color. Also, the puzzle name is displayed in the window title. (The code is a one-liner, which I unfortunately forgot to add before the 4.4 feature freeze.)

It is now possible to select multiple pieces at once, either by holding Ctrl and clicking on the pieces, or by dragging a rubberband around the pieces. All pieces will then be moved at once when you drag one of them. The selection ...read more...

Ivan

System & Utilities

First of all, I need to apologize for not doing this earlier – I was rather busy lately.

The other problem is that “remember the milk” plasmoid is ruining/spoiling me. Until I started using it, I somehow found the time to do stuff in order not to forget what I need to do. This way, when I have a reminder, I can postpone most of the items in it indefinitely. ;)

So, without a further ado, I present the first public release of the fantastic, greatest and uber-awesome brand-new (and did I say fantastic and awesome?) plasma theme named ASCII (it is awesome… and fantastic… and unique… and gorgeous… and uniquely fantastic… and awesome…):

Mehrdad Momeny (mtux): An idea to speed up Choqok development

System & Utilities

As you heard before, I’m doing military service and it’s some kind of non-profit job right now :-/

Recently I’ve noticed that i have to do some jobs to earn money. But this way will take most of my free time, and there couldn’t be time to do My favorite job, i.e. working on Choqok and Blogilo.

Some days ago, An idea came in my mind, I discussed with some close friends about if this idea could work, and now I want to talk with you about it.

The idea is some kind of sponsoring Choqok development by it’s users:

There are so many features we can implement! from new microblog services (like friendfeed) to additional useful automatic tasks (like translation of dents/tweets)

We define some kind of minimum donation requirement to implement one special feature/idea.

And then users who want to have that feature sooner, and like to participate in its development, will decide to donate some amount of donation required to implement it(Whatever that is important to them)! And then, After donation ...read more...

Kompiling in a virtual machine made fast

System & Utilities

As you may have followed, I compiled my KDE in a virtual machine , described an example how it goes and even compared compile times in a mini-benchmark . I stopped using a virtual machine later because VirtualBox only gives you one virtual CPU, QEmu as well, and VMware Server only two.

Tom Albers: Sysadmin Quickies

System & Utilities

Last weeks, a couple of things happened in the KDE sysadmin area, just some small updates:

  • Eike Hein, Ingo Malchow and Jeff Mitchell are now part of the sysadmin team too. Account creation was already fast, and with the addition of these folks, it has become even faster. All day-to-day business, should be quick and painless now.
  • We hang around at #kde-sysadmin on irc, so if you want to talk to us, feel free to hop in, although we often will request creating a sysadmin bugreport, so that there is an archive.
  • The l10n-server has been replaced by new hardware and a new hosting location. Mainly known as ’scripty’ by most of you.
  • The SVN-server has been replaced by new hardware. It was a difficult move which was pending for a while. In the end Dirk was forced to move to the new server due to hosting difficulties on very short notice.
  • anonsvn has become more reliable as we have a new anonsvn mirror. This now means we don’t get into trouble as soon as one is down.

Thiago Macieira (thiago): Happy Birthday, Mr. Repository

System & Utilities

In order to commemorate this important day today, I thought I’d give credit to someone who has just had an anniversary a few days ago: the Qt open repository. I put together this family album for the important moments in this 1 year and 3 days.

album1.png

March 23, 2009: The repository is born

You were born in a chilly morning, with 30607 files and 3135 directories. You weighed only 150 MB and you had two branches (4.5 and master).

Your older brother, qt-history (who was 15 years, 5 months, 19 days old) was very proud of you.

 

album3.png

May 11, 2009: You found a home and a family to take care of you

The Gitorious family welcomed you with open arms. From this day on, you had a permanent identity and address, http://qt.gitorious.org/qt/qt.

Your cousins qt-jambi and qt-creator joined you in this new family, among other distant Open Source cousins.

Kevin Krammer: Transissions

System & Utilities

Today was my last day at AviBit Gmbh where I have been working for almost nine years now.
Starting with development of internal tools, becoming maintainer of some of the companies main components and finally designing and supervising implementation of a versatile client framework for our surveillance products.
What a ride Smiling

Nine years of Qt development for multiple platforms (mainly Linux though), on a KDE powered desktop using my personal favorite editor Kate.

Nine years seeing Linux grow on both servers and workstations in an industry (air traffic control solutions) which has been using proprietary Unix on server and Windows on workstations (though some competitors also have workstation offerings Unix like systems).

It has always been interesting to see how using Qt can give a new player like AviBit a significant advantage in public tenders by reducing time to implement features (lots of code sharing between clients and servers) and by being able to deliver on the customer's platform of choice (or by being able to deliver on the previous suppliers ...read more...

Anne Wilson (annew): KDE Photo Tutorials

System & Utilities

Some two years ago Uga wrote some wonderful blogs explaining techniques for quality photo editing (Uga’s Blog).  His host didn’t store the actual photos, and in an unfortunate accident the ones belonging to some of the blogs were lost.  I’d dearly like to have all of these on UserBase.  The remaining blog, 1-1: Levels adjust is referenced on UserBase. There were also

  • 1-2: Curves adjust
  • 1-3: White balance and
  • 1-4: Brightness/Contrast/Gamma + Hue/Saturation/Lightness

We had a link to the last one on UserBase – but it appears to be an incomplete address, so I don’t know whether that was lost too.

With the number of keen photographers in KDE there is a distinct possibility that someone saved a copy of those tutorials.  If they could be located I’d ask permission to put them (in entirety, not as references) in UserBase.

Such tutorials should not be lost.  If you know other material that should also be preserved on UserBase, please let me know.

Mark Kretschmann (markey): KDE at OpenExpo 2010

System & Utilities
Left to right: Heike, Klaas, Myriam, Mark


On Wednesday and Thursday a delegation from KDE represented our Kool Desktop Environment at OpenExpo in Berne, Switzerland. Unfortunately I couldn't make it on Wednesday, so that Heike, Klaas, and Myriam were rather busy handling the booth (their voices started to sound rather strained). But yesterday I found some time and could help out a bit.

Klaas Freitag is working for Novell (openSUSE team), and in his spare time he and his wife Heike create a very promising application for businesses, called Kraft. Myriam Schweingruber is from KDE/Amarok/Kubuntu/FSFE (is there anything she doesn't do?), and myself of course I'm from Amarok and KDE.

The event itself generated mixed feelings due the stronger commercial orientation than usual, resulting in less space for Free Software, while the business side (called Topsoft) was more emphasized this time. However, this was not the fault of the organizers (the ...read more...

Ariya Hidayat: multiples of 3 or 5

System & Utilities

One day Helder showed me Project Euler, a collection of interesting math problems to be solved using computer programs.

I took a look at the first problem: find the sum of all the multiples of 3 or 5 below 1000. Getting the linear time solution was trivial, the constant time solution was also not hard. However, I could not help it, I continued by applying some obfuscation voodoo and came up with this answer (of course, constant time as well):


return \"uncopyrightable\"[n % 15] - 'a' + 44 - \"xzoxy}pge]_LAKD\"[n% 15] +
'A' - (!(n % 15)) * 9 + 15 * ((n / 15) * (4 + (\"aaabbcdddeffggg\"[n % 15] - 'a')) +
(n / 15) * (n / 15 - 1) * 7 / 2);

How did a word ("uncopyrightable") end up in that solution? Believe me, it was (a lot of) fun! :)

Dennis Nienh

System & Utilities

At some point I applied my programming habits to my car. I keep it clean now; empty bottles and garbage are long gone. Ironically, this is driven by laziness. Among the things that are still with me and my car is a routing atlas. Its right to exist stems from its independence of battery power and satellites. Occasionally I complement it with printed routes, the single-use atlas mostly useful when driving alone.

Back in the days when Google was only a search engine I used a free (as in beer) service — was it called Map & Guide? — to create these printed routes. Even short routes resulted in four or five pages, quite a mess in a car. Todays services are much better, creating customizable, short printouts. Tomorrow I want Marble to print my routes.

Soon I realized that this feature is easier realizable than expected: Marble already has printing support for maps and Qt’s QTextDocument simplifies creating printable pages with a nice layout. Below is a screenshot from my printing Git branch:

Tomaz Canabrava (tomaz):

System & Utilities

I wrote this post a month back, but just now I have decided to post it.

Well, some weeks back i commited an initial project for plugins on Rocs, and it’s almost finished… but i had a question about life, the universe and everything: Why i took too long (3 weeks) to put it to work ?

First, i have some others stuff to do, but, this is not a true answer…

Second, I started with QtPlugins, It worked very well! But, and it is a big but, how will Rocs know the location of the installed plugins? since plugins are shared lib loaded at runtime, I had to make this work somehow. So at IRC, #kde-dev, Rakuko told me something about KServices, unknow by me till then. So, with a little search on the KDE api, i found the rigth way (or KDE way) to make it works flawessly.

So, I had to stop doing with Qt Plugins and rewriting everything to use KServices, back from line zero. =)

After some hack. i had a problem loading the ...read more...

Bruno Abinader (abinader): Hello Planet KDE!

System & Utilities
Hi!
This is my first post on the Planet KDE, so I would like to take advantage of this to introduce myself :)
My name is Bruno Abinader (aka. abinader on Freenode), and I'm an open-source developer guy which lives in Manaus, Brazil and works for the OpenBossa labs/INdT since 2005. I've started contributing to the Plasma project since January/2010 (doing some ports of the deprecated animation API usage to the current one) and plan to keep contributing with cool stuff like new animation effects, MediaCenter plasmoids (Last.FM currently in progress!) and mentoring in some GSoC ideas (like Plasmoid data caching and core library test suite). For this little time I've been working on Plasma I would like to thank some people that helped me begin this the right way: Savago, igorto, notmart and aseigo, thanks!

ps: I must recognize I'm not an avid blogger, but I'll try to keep things in touch for now on :D

Michael Pyne (mpyne): Bug of Legend

System & Utilities

So. Those of you who notice the things I post will presumably notice I haven’t blogged as much recently. Essentially it’s because I have less time for development between school and work (I’m on shore duty so I don’t deploy, but I’m in charge of a division so my hours are still substantial).

The spare time I have had over the past month I’ve mostly spent trying to (re) fix my new favorite bug ever, bug 182026 which is a crash bug in KPixmapCache::discard().

You should hopefully have no clue about what KPixmapCache is other than that it’s what’s crashing most of your favorite apps, so I’ll give you the rundown. Back when KDE 4 was being developed and we were shifting to use the shiny SVG icons and graphics everywhere it was noticed that rendering SVG graphics took rather more time than simply loading a PNG from disk. So, instead of loading a SVG file from disk every single time it was needed, the end result (a PNG) was cached to disk instead, and a quick ...read more...

Chani Armitage (Chani): standing out in the crowd

System & Utilities

Today is Ada Lovelace Day – celebrating the very first programmer, who also happened to be a woman. Appropriate, then, that last night while I was surfing the interwebs I stumbled on a blog called Infotropism – specifically one post, standing out in the crowd. It’s nearly a year old, but it was a good read nonetheless – and things don’t seem to have changed much in that year, anyways.

It seems like an interesting blog in general – a post on community management caught my eye. I wonder if KDE has written down any of our communal wisdom on managing our own community… it’s something I’ve always meant to look into when I’m less busy (as if that will ever happen ;)

George Goldberg (grundleborg): Telepathy Contact List Update

System & Utilities

A while ago I wrote about the Realtime Communication project – to integrate the power of Telepathy into KDE. I thought it was probably time to write a little update, so without further delay, here’s a screenshot of the Contacts List.

Telepathy Contact List Screenshot

So, what’s new?

  • Icons indicating the presence status of contacts
  • Groups! These are synchronised with the server where the IM protocol supports it.
  • Meta contacts – these are not fully implemented yet, but the little + signs next to each contact in the list show they are partially there. At the moment, fake meta contacts are created for all contacts, but support is nearly complete for real metacontacts where the user has indicated two contacts belong to the same person.

Meta contacts in particular are exciting because they use Nepomuk’s PIMO ontology, meaning that they are accessible not just to Instant Messaging applications, but can be used by any Nepomuk enabled ...read more...

Ada Lovelace


As a scientist, I inhabit what has been seen as a male-dominated world, but that is changing. Here at NOCS, I joined the PhD program as part of an intake that was around 50% female and that is reflected in other PhD years too and – largely – among the younger postdocs.

KDE does relatively well among free software communities when it comes to attracting female contributors, but that shouldn’t hide the fact that compared to the wider world we still do pretty badly. The issues are likely complex and will take a long time to change, but I’m sure ...read more...

Adriaan de Groot (adridg): Printemps non O Lent

System & Utilities

Back from Vienna: check. Presentation for FSFE successful: check. Gift for MOMC given: check. Color of Danube HTML-ified: 6093D1. Health: still not there. While it’s getting to be severely spring here, I’m still wrestling with the tail end of the epic cold / pneumonia / general malaise that I picked up mid-january.

So I’ve seen a number of things go by that I feel I should have commented on, or reacted to, or written critiques of, but didn’t. Things like Aaron’s 10 challenges for the year; or Jos’ Freedom series; or the how-and-where-to-critique-most-usefully blogversation (ugh, cut out the neologisms, plzkthx). The EIF2 has been updated (in draft form, still) and ACTA has been leaky. The MPL is being re-vamped. The NLUUG spring conference is coming up. Akademy and GUADEC calls for participation have been published.

Running behind terribly on everything, that is.

Holger Foerster (foerster): digiKam with another database backend than SQLite

System & Utilities

Last summer I saw Bug #127321 an thought, this can be done by me (partly at least).
After some (successful) prototypic implementation, most of the time where spent into smooth integration in the existing
project:

  • adding a solution for migrating from SQLite to MySQL and vice versa
  • add possibiliy to start an own database server
  • and bug fixing...

Because only a few persons trying out this work (which resides atm. in a dedicated branch), the most bugs are possible undiscovered.

So if you are brave enough to crash your whole existing database structure (images are not touched), have a little amount of free time or you would like

I wrote before about testing a proxy model by visual inspection in the proxymodeltestapp. For identifying the sources of issues this has generally worked really well, but the involvement of human interaction means that it doesn’t scale and is error prone. Unit testing fares better in that regard because they can be run automatically without a human operator or observer, are faster than unit testing and are a persistent test for regressions so they allow for broad refactoring if needed for performance reasons.

This is not a very screenshot-able subject, so I have added some cat pictures at the suggestion of and for the amusement of tokoe.

Getting the blues

The biggest problem with Qt Model View is the amount of API that must be implemented to write a proxy model. Aside from implementing the QAbstractItemModel interface and the small additional interface in QAbstracyProxyModel, an observer interface for ...read more...
