Kat Desktop Search Environment is an open source framework designed to allow KDE applications to index and retrieve files; loosely speaking, a search tool. Tuxmachines has had the rare opportunity to speak with Roberto Cappuccio, wonderfully talented developer of KAT.

Roberto is a 38 year old student in Bolzano, Italy, working on his Master of Science degree. Previously a software consultant for his own company, he is now the System Administrator of the Faculty of Computer Science at the University of Bozen-Bolzano. He's not married, but he is in a committed relationship, gals.

According to the website, Kat is similar to the Windows applications WhereIsIt and Google Desktop Search. Metadata, fulltext and thumbnails are extracted from documents, images, mp3 and other media allowing quick and accurate information retrieval.

Also being featured on kde-apps.org, one can find a quick howto, brief changelog and more screenshots of this wonderful utility there. svn is available here.

As you might recall, KAT now ships with MandrivaLinux and the index tool is present by default in the system tray on their 2006 desktops. In addition, Roberto states that Kubuntu ships with KAT and "Debian is evaluating the possibility of including Kat in Etch."

        



TM: I notice a few distros are shipping with Beagle, how is yours different? better?

Roberto: From a technical point of view:
Beagle is a Gnome application, written in C# (and another 2 or 3 languages), using the MONO library and lucene. Kat is a KDE application, written in C++, using KDE and KIO libraries, using and extending the KDE architecture.

From a functional point of view:
Beagle is only a Desktop Search engine, like Google desktop search. Kat technology will be used as a base for the Context Linking engine of KDE called Tenor. This means that we index files and content like Beagle, but then we go beyond this and link the items based on their context.

The result is: better and more accurate search.

TM: What distro do you run most of the time? favorite distro?

Roberto: Debian SID, but right now I'm using Kubuntu, which is more user friendly.

TM: When did you first start using linux, what was your first experience, why when what etc?

Roberto: I have always been a Windows power user. I tried Linux a lot of times during the past years but I found it terribly unstable and mostly unusable. Six months ago I had to do an assignment for a course in Data Mining and it had to be done in C++ in Linux. So I armed myself with patience and discovered Debian. That project has become Kat.

TM: Are you actively involved in other open source projects, what if any, are some of your other projects?

Roberto: Yes, I will collaborate with the Tenor team in order to create the new Search Engine for KDE, which will incorporate also Contextual Linking.

TM: Why KAT?

Roberto: It is a word joke. It creates catalogs, it is developed for KDE (and you know that almost all KDE apps have a name beginning with K), so it should have been called Katalog, but an application with that name already exists... So I contracted it to Kat. I love cats (I have always had cats around), so the similarity between Kat and cat made the rest. I also designed Kat logo.

TM: What's in the future for KAT?

Roberto: Kat will remain an application on its own as long as we manage to merge it with Tenor. Then it will survive inside of Tenor, as the Content Search layer.

TM: Would you like to say hi or anything to anyone? Or do you have a message you'd like published?

Roberto: I'm searching for a sponsorship from a big software company, like the one Trolltech offered to Aaron Seigo. I need to work a lot to Kat and Tenor, but I also have to work for my university. If I could get a sponsorship, the evolution of Kat could be much more quick.

Tuxmachines found Roberto to be an extremely nice and accessible developer, and very much enjoyed doing the research on this wonderful application for this article. I encourage everyone who desires a comprehensive search utility to install and use Kat. Visit the home of Kat and look for Kat in the upcoming release of Mandriva 2006.

LibreOffice Help From FSF, Mike Saunders

  • New FSF membership benefit: LibreOffice certification
    The Free Software Foundation (FSF) today announced that the opportunity to apply for LibreOffice certification for migrations and trainings is now available to FSF Associate Members. LibreOffice is a free software project of The Document Foundation (TDF), a non-profit based in Germany. An office suite, LibreOffice encompasses word processing, and programs for the creation and editing of spreadsheets, slideshows, databases, diagrams and drawings, and mathematical formulae. It uses the ISO standard OpenDocument file format (ODF).
  • Marketing activities so far in 2017: Mike Saunders
    Thanks to donations to The Document Foundation, along with valued contributions from our community, we maintain a small team working on various aspects of LibreOffice including documentation, user interface design, quality assurance, release engineering and marketing. Together with Italo Vignoli, I help with the latter, and today I’ll summarise some of the achievements so far in 2017.

Debian/Ubuntu: Q4OS, Ubuntu Dock and LXD Weekly Status Update

  • There's Now a Windows 10 Installer for the Debian-Based Q4OS Linux Distribution
    The Q4OS development team is pleased to inform us today about the immediate availability for download of a Windows installer for their Debian-based GNU/Linux distribution, Q4OS, allowing users to create a dual-boot environment on their PCs. For those not familiar to Q4OS, it's an open-source and free Linux distro based on the popular Debian GNU/Linux operating system and built around the Trinity Desktop Environment (TDE), which resembles the look and feel of the old-school KDE 3.5 desktop environment. Created with an emphasis on Windows users who want to migrate to a free, open-source, and more secure operating system, Q4OS now lets them install the distribution alongside Microsoft Windows in an easy manner, without having to do any modifications to your personal computer or install any other apps.
  • Ubuntu Dock Now Has Dynamic Transparency
    Ubuntu devs have listened to our gripe on the jarring contrast between GNOME 3.26's transparent top bar and the Ubuntu Dock.
  • Ubuntu Dock Features Adaptive Transparency on Ubuntu 17.10, Here's How It Works
    Ubuntu contributor Didier Roche continues his development on the look and feel of the upcoming Ubuntu 17.10 (Artful Aardvark) operating system, and today he announced that Ubuntu Dock is getting adaptive transparency. Canonical confirmed that Ubuntu 17.10 would come with the GNOME 3.26 desktop environment by default, though the default session has suffered numerous modifications compared to the vanilla one to make things easier for those using the Unity interface on Ubuntu 17.04 (Zesty Zapus) or Ubuntu 16.04 LTS (Xenial Xerus). Most probably, Ubuntu 16.04 LTS users won't upgrade to Ubuntu 17.10, but we're sure Ubuntu 17.04 users will because it'll reach end of life in about four months from the moment of writing, sometime in January 2018. Therefore, Canonical wants to make their Unity to GNOME transition as painless as possible.
  • LXD: Weekly Status #15
    This week has been pretty quiet as far as upstream changes since half the team was attending the Open Source Summity, the Linux Plumbers Conference and the Linux Security Summit in Los Angeles, California.

Events: KDE/Randa 2017 and Linux Foundation

  • KMyMoney’s Łukasz Wojniłowicz in Randa
    Please read the following guest post from Łukasz who joined me last week in Randa to work on KMyMoney.
  • Randa 2017 – Databases are back to KMyMoney
    On the morning of Day 5 we chased and fixed a problem that was introduced a long time ago but never caused any trouble. The code goes back into the KDE3 version of KMyMoney and was caused by some changes inside Qt5. The fix prevents a crash when saving a transaction which opens an additional dialog to gather more information (e.g. price information). With the help of other devs here in Randa, we were able to drill down the problem and update the code to work on KF5/Qt5 keeping the existing functionality.
  • Randa 2017 – Days 3 and 4
    On Day 3, we started out at 7:02 as usual with the team responsible for breakfast meeting in the kitchen. KMyMoney wise, we worked some more on keyboard navigation and porting to KF5. The dialog to open a database and the logic around it have been rewritten/fixed, so that it is now possible to collect the information from the user and proceed with opening. The database I have on file for testing does not open though due to another problem which I still need to investigate.
  • Watch the Keynote Videos from Open Source Summit in Los Angeles
    If you weren’t able to attend Open Source Summit North America 2017 in Los Angeles, don’t worry! We’ve rounded up the following keynote presentations so you can hear from the experts about the growing impact of open source software.
  • uniprof: Transparent Unikernel for Performance Profiling and Debugging
    Unikernels are small and fast and give Docker a run for its money, while at the same time still giving stronger features of isolation, says Florian Schmidt, a researcher at NEC Europe, who has developed uniprof, a unikernel performance profiler that can also be used for debugging. Schmidt explained more in his presentation at Xen Summit in Budapest in July. Most developers think that unikernels are hard to create and debug. This is not entirely true: Unikernels are a single linked binary that come with a shared address space, which mean you can use gdb. That said, developers do lack tools, such as effective profilers, that would help create and maintain unikernels.
