In reply to interesting comments to my previous blog on Strigi and xAttr support in KDE4, I would like to suggest the following mockups, which I would find very useful. The deal with the ability to store keywords, for example, not but necessarily using xAttr. I have no idea on how to implement these mockups, so any help or pointers are appreciated.

With some help, I got the kfile stream analyzer for Strigi working. This means that Strigi will now index the meta data fields defined by the kfile-chemical plugins. The problem why it was not working earlier, was that it segfaulted on every creation of KDE classes. That’s something I really hate about C/C++: the lack of stack traces, though valgrind was helpful. It turned out that adding the below line fixed all.

Desktop searching has become a hot topic (some earlier blogs ), now that years of data accumulated on ones hard disk: PDFs, OpenOffice.org documents, Latex manuscripts, old Java source code, digitized music, and a lot of chemical files. Well, on my hard disk that is. Unlike piles of paper, a computer could search this data, but due to the size an index is required. What’s KDE4 going to offer?

Geoff Hutchinson blogged about his OS/X ChemSpotLight, an indexing tool for chemistry documents. It’s like, but more advanced than, the kfile_chemical and Kat I have been working on (with others) for the KDE desktop (see earlier blog items). ChemSpotLight currently does more than the KDE tools: it adds Spotlight comments. I assume these are like the Linux extended attributes, used for example by Beagle.

One of the things I had not fully figured out up to today, was how to configure my Kubuntu system to easily view DVDs on our TV, using my NVIDIA’s TV-OUT. I’ve seen xorg.conf files that define a X11 server for the monitor and a second for the TV, and files that use TwinView. Now, I did not really like the way first option worked, so tried the second.

After the three obligatory days of christmas holidays (fun, especially with two children, but very exhausting), it is time to get back to business again. I’m still at my father-in-laws place with only XP installed, so booted the Knoppix 4.0.2 DVD I burned last friday. Eclipse is not working, but being able to use Kmail to read my email again is just what you need as in internet-junkie.

KDE 3.5 was released with lots of changes. SuperKaramba is now a standard KDE application and is neatly integrated. It allows embedding themelets on your desktop background. It shows several themelets: the weather, a calender, a toolbar with applications, a FoldingAtHome monitor , the contents of the clipboard, the music that is playing (Cake) and a simple todo list. All customizable up to the pixel.
