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.

This week in KDE: all about the apps

This week we landed a lot of nice improvements for KDE’s apps, which I’ve highlighted below! Of course we didn’t forget about Plasma, so have a look-see... Read more

Rolando Blanco: Ubuntu Desktop Makeover

I must confess that since Ubuntu started, there have been a lot of changes that we have experienced on our desktop (each time for the better). However, I have always loved changing its appearance, to one more according to my particular tastes, sometimes up to 3 changes per year. This is one of the features that I like most about GNU / Linux, the freedom to adapt everything to my liking. This time, I wanted to make some slight changes in search of elegant minimalism. This is how I started testing a new icon pack and a tool that works as a widget and that animates my desktop, for this I used Conky. Read more

WiFi Goes Open

For most people, adding WiFi to a project means grabbing something like an ESP8266 or an ESP32. But if you are developing your own design on an FPGA, that means adding another package. If you are targeting Linux, the OpenWifi project has a good start at providing WiFi in Verilog. There are examples for many development boards and advice for porting to your own target on GitHub. You can also see one of the developers, [Xianjun Jiao], demonstrate the whole thing in the video below. The demo uses a Xilinx Zynq, so the Linux backend runs on the Arm processor that is on the same chip as the FPGA doing the software-defined radio. We’ll warn you that this project is not for the faint of heart. If you want to understand the code, you’ll have to dig into a lot of WiFi trivia. Read more

Kernel: Linux 5.8, Linux 5.7, FSGSBASE and HWMON

  • Improved EXT4 + XFS DAX Implementation Appears Ready To Go For Linux 5.8

    Adding to the expected changes for Linux 5.8 is improved EXT4 and XFS file-system direct access "DAX" support. DAX is the means of direct access to files backed by persistent memory (such as Intel Optane DC Persistent Memory) without needing to be copied via the page cache. Thus DAX bypasses that extra copy for reads/writes to the storage device and mapping the storage device directly into user-space.

  • The Top Linux 5.7 Features From Apple Fast Charge To Official Tiger Lake Graphics

    Assuming no last minute concerns, the Linux 5.7 kernel is set to debut as stable this weekend. Given all the weeks since the merge window and our many articles covering all the feature activity at that point (and not to be confused with our activity of new work being queued for the upcoming Linux 5.8 cycle), here is a look back at some of the top features of the Linux 5.7 kernel. Among the most interesting new features and improvements for Linux 5.7 include: - Intel Tiger Lake "Gen12" graphics are now enabled by default in being deemed stable enough for out-of-the-box support where as on prior kernels the support at the time was hidden behind a kernel module parameter.

  • Performance-Helping FSGSBASE Patches Spun For Linux A 13th Time

    The FSGSBASE Linux kernel patches that have the potential of helping performance going back to Intel Ivy Bridge era CPUs in select workloads have now hit their 13th revision to the series in the long-running effort to getting this support mainlined.

  • Linux's Hardware Monitoring "HWMON" Picking Up Notification Support

    In addition to the AMD Zen "amd_energy" driver coming for Linux 5.8, another late change now queued into hwmon staging is introducing notification support for the hardware monitoring subsystem. HWMON subsystem maintainer and Google employee Guenter Roeck has queued up notification support for this subsystem. This serves as a generic notification mechanism not only to notify user-space but also the thermal subsystem for any HWMON driver events. In the HWMON context, these events could be important like warnings/critical alarms over detected temperatures or voltages for different components.
