KDE 4.10 Released, the Fastest KDE Ever 184

Posted by Unknown Lamer from the giving-people-what-they-asked-for dept.
sfcrazy writes "The KDE team has announced the 4.10 releases of KDE Plasma Workspaces, Applications and Development Platform. It brings many improvements, features and polishes the UI even further, which already is one of the most polished, stable and mature desktop environments. With 4.10 KDE users can experience a much more sane global-menu like implementation without interrupting their workflow. A list of improvements is available here." This release makes major steps toward further Qt Quick/QML integration (more plasmoids are written using QML, you can create animated desktops using QML, etc.). KWin's configuration applet also supports fetching extensions from KDE Look. Perhaps the best improvement is a new indexer for Nepomuk, with claims that the semantic desktop is finally usably fast (after suffering through a multi-week indexing on my laptop, I have to say Nepomuk is really cool, but having an unusable system for that long is not so I for one welcome our new indexing overlords).

      This is actually a legit question. Mark Shuttleworth has repeatedly praised Qt. He has forked away from Gnome. The new Ubuntu phone interface is apparently written in Qt, and he is encouraging developers to write Qt/QML apps for his new phone platform.

      I bet Ubuntu could recreate their Unity interface in Plasma/Qt easily enough. But the really interesting aspect of that is that they could create one device that could easily change UIs/shells based upon how it was used. A tablet could default a touch interface, but switch to a more traditional interface with paired with a keyboard. A phone interface could change to a desktop interface in a dock.

    Just to clarify for people, the new Nepomuk indexer was COMPLETLY and UTTERLY rewritten from scratch and shares ZERO of the old code. IT uses 2 pass indexing just like OS X-- pass 1 is just file name and location so that basic search works. Pass 2 is when it starts figuring out music tags or director tags for movies , things like that.

    One of the reasons the old indexer was so slow would be because you could search by content WITHIN the files, unfortunately it would scan every file, even those without any useful content for indexing like movies or music. This does mean some reduced functionality but it also means a lot more stable and quick system.

    Also STRIGI has been completly thrown out so thats not an issue anymore.
