KDE PIM November Sprint

KDE News - Lun, 03/03/2014 - 13:31

KDE PIM sprint Nov 2013

In early 2013, it was established that "Osnabrück is not a place". Meaning that the KDE PIM spring sprint, which traditionally takes place in Osnabrück, could happen at a different location and still be a continuation of the tradition.

KDE PIM's autumn sprint has traditionally been in Berlin, but since the team decided that "Berlin is not a place" applies as well, this year's installment of the sprint took place in Brno in the Czech Republic.

Even people without the exceptional skills of Sherlock Holmes have certainly deduced by now that KDE PIM sprints happen in cities that are not places but coincidentally contain the letters B, R and N.

Now, without further procrastination, the story about the KDE PIM autumn sprint, brought to you by KDE e.V., Red Hat and the letters B, R and N.

Early birds

Unlike with most other sprints, where all but some local people arrive on the first day of the sprint, there had already been a week of intense KDE hacking been going on.

Bob - you remember Bob? - and his merry henchmen from the KDE Barcelona Squad, had already arrived earlier that week and hacked on various pieces of KDE software and had beer delivered to them on trains. Yes, trains! That's the Czech Republic for you.

Notes

We're sorry to have to notify you of the fact that nobody worked on KNotes. There were plenty of old school sticky notes though. Because Kevin Ottens likes to draw rectangles on white boards and sticky notes are a natural choice for filling them.

There were also a lot of notes taken, notably on the outcome of the discussions which were scheduled by moving notes on the whiteboard.

This kind of structured handling of topics is a noteworthy improvement over some of the previous sprints and very necessary given the increased number of people who nowadays attend and take note of them.


Back row: Lukas Tinkl, John Layt, Michael Bohlender, David Edmundson, Ingo Klöcker, Daniel Vratil
Middle row: Kevin Krammer, Martin Klapetek, Mark Gaiser
Front row: Christian Mollekopf, Alex Fiestas, Vishesh Handa, Jan Grulich Bugs

As has become tradition, a significant portion of the meeting was dedicated to mercilessly squashing those nasty little buggers. David Faure, a man who certainly needs no further introduction, used the presence of several component maintainers to get issues fixed. "Getting fixed" meaning he did the actual fixing, being aided by the aforementioned component specialists with insight into inner workings and assumptions of the respective code.


Hackers' vitamins

The previous and current maintainers of Akonadi had fun with things so deep down in the guts of the system that not even the author of this article would be able to fully understand them. Those people are way smarter than him!

In addition to fixes in the sense of correcting erroneous behavior, this also included several improvements in the area of runtime performance. And a faster KDE PIM makes everybody happy.

Progress

One of the other fun aspects of a sprint, aside from the obvious awesomeness of hanging out with great people and doing interesting code work, is to ponder and prototype potential progressive programming pieces.


Big ass pizza!

Mark Gaiser, Michael Bohlender and Thomas Pfeiffer had a closer look at how to get beyond quaint, dare I say boring, user interfaces and enable QtQuick-based applications to tap into the power provided by KDE PIM libraries. Some example code was written, plans were drawn - but much is still to be done.

Secrets

Naturally the presence of the KDE Barcelona Squad made secrecy a paramount objective. Not only do we need to hide their identities, a job made easy by several Squad members disguising themselves with enormous fake beards, we are bound by oath—under threat of dragonian punishment—to not talk about rocket science like advances in PIM data search. Well, "rocket science" doesn't even cut it, more likely on the level of warp science!

Editor's note: recent leaks have nothing, absolutely nothing, to do with our ability to keep things, you know, secret. Really!

KDE and Google Summer of Code 2014

KDE News - Mar, 02/25/2014 - 12:47

KDE is happy to announce that it has been accepted as a mentoring organization for Google Summer of Code 2014. This will allow students from around the world to work with mentors on KDE software projects. Successful students will receive stipends from Google.

The Google Summer of Code program offers development funding as well as mentors to students who want to work on open source software projects. The program provides students the opportunity to learn more about coding, work within structured software development environments, and push bug fixes and new features into real-world, production software. For Google and the rest of the world, the program provides improvements to the software that millions of people use on a daily basis.

The ideas on what a student entering the GSoC program might work on are offered from developers and users alike. The KDE project has a list of potential projects for 2014 on the Community Wiki. Depending on what students choose to develop, this could mean it will be a big year for popular KDE software such as Amarok, digiKam, Marble, Krita and the PIM suite as well as more niche applications and libraries.

KDE's Next Generation Semantic Search

KDE News - Lun, 02/24/2014 - 11:57

For years, KDE software has included a semantic (relationship-based) searching infrastructure. KDE's Semantic Search was built around concepts previously developed in a European Union-funded research project NEPOMUK which explored the use of relationships between data to improve search results. Based on these ideas, KDE's implementation of Semantic Search made it possible to search for all pictures - taken in - a particular place. On top of that, it added text search and tagging.

Incremental improvements

Since its implementation, our developers received and digested a lot of feedback. Application developers requested and received easier to use APIs (Application Programming Interfaces, glue for integration) and widgets (such as the star rating and tagging user interface). For end users, stability and performance were crucial. Much work was put into improving the speed of indexing, keeping it out of the way of users and making Search more reliable.


Vishesh Handa talking about relationships* at conf.kde.in
(*the technical kind) What is coming

The upcoming release of KDE Applications (version 4.13) will introduce the next step in the effort to improve the performance and stability of search features in KDE software. The improved Semantic Search is lighter on resources and more reliable than it was previously, but, thanks to considerable reuse of existing code, it is mature and offers a complete feature set. Users will find that features such as search are exposed in the same, familiar manner - but searching in a variety of applications will be faster and more reliable.

To accomplish this, developers looked at how Search was being used in practice. The major use-cases they identified are:

  • Finding objects (like files) based on their content, requiring a full text index of files on a system
  • Storing and retrieving simple objects such as tags, ratings, activities etc.
  • Storing and searching through relationships like this file is related to this contact

With a better understanding of use-cases that developed during years of deployment and development, the improved Search technology was specifically designed to do these three things and do them well.

Advancements for end users

The improved Semantic Search brings our users a number of tangible benefits. Its design is more robust, delivering search results quicker and with less overhead. The simplicity of the design will not only reduce failures, but will also make it easier for current and new contributors to add and improve functionality.

Improvements that users will notice:

  • Faster searching and indexing
  • Searching is more accurate
  • More reliability
  • Faster software development

Applications like the Kontact Suite, Dolphin and Gwenview, as well as the Plasma Desktop itself, already benefit from the changes.

For developers

The changes are small enough to make it relatively easy for application developers to move their applications over to the improved Semantic Search, which many have already done for the 4.13 release of KDE Applications. Instead of having a single RDF-based database for all information, Semantic Search now provides separate data stores and search interfaces. This allows it to store and search each type of content in an optimal way. Under the hood, the Semantic Search infrastructure uses SQLite and Xapian to index and retrieve data. More information about the information retrieval architecture can be found on the Community Wiki.

As of today, Semantic Search offers developers:

  • An API for searching
  • A way of storing relations between entities
  • File indexing
  • Email and contact indexing
  • Timeline KIO slave

Developers can find more information on the Baloo wiki page.

KDE Platform 4 and KDE Frameworks 5

When upgrading to KDE Platform 4.13, existing tags, ratings and comments will be transparently migrated to the new storage system. Looking forward even further, Semantic Search is in the process of being ported to Frameworks 5. This Frameworks 5 version will use the same storage system as the version included in Platform 4.13 (and newer) and will be fully compatible with it.

Learn more about Frameworks 5 in the tech preview announcement.

Conclusion

The change to Semantic Search in KDE is a natural next step in the process of taking technology that came out of an academic research project and adapting it to real world use cases. KDE's Semantic Search is at a point where it has become a core part of our infrastructure. It is now well positioned to provide the required robustness and functionality.

Christian Díez (Malcer): Caledonia 1.6.1: “bugfixes” y actualización recomendada

Planet KDE Español - Dom, 02/23/2014 - 12:16

Exceptuando en sus comienzos, nunca tuve que lanzar una versión “de arreglo” de Caledonia, pero es que de nuevo está justificado, muy a mi pesar. Esta versión 1.6.1 es una actualización altamente recomendada, sobre todo para los usuarios de Plasma-nm y KDE Connect. Para el primero, contiene unos iconos “parche” para intentar que mantenga más compatibilidad con las versiones 4.2.x del nuevo Plasma Network Management en QML. Para el segundo (KDE Connect) contiene soporte para la nueva versión recientemente liberada (en algunas distros se está denominando 0.5.x, y en Google Play ya se actualizó para los dispositivos Android y compatibles con las APK).

Otro detalle menor es la incorporación de la variante brasileña del idioma portugués en la metadata.

Una situación un poco fastidiosa para mi y para los más de 1.200 usuarios que descargaron y/o actualizaron el tema desde la muy reciente versión 1.6, pero las cosas han venido asi. Ante la duda de si muchas distros van actualizar más allá de las versiones 4.2.x de Plasma-nm era necesario intentar ampliar la compatibilidad con éstas. Y ante el nuevo código de KDE Connect también se hacía necesario, por supuesto.

Podéis descargar esta nueva versión desde su habitual sitio en SourceForge. Para más información sobre la instalación y recordar más novedades, podéis leer la parte final del artículo del lanzamiento de la nombrada versión 1.6.
