KDE in Two Slides

What's new in KDE4?

Hands on Demo – KDE4 Alpha aka very few things work ;-)

Why I think KDE is cool (& useful)

What is KDE Desktop Env – like GNOME, CDE, Xfce, runs on top of X11 Written in C++ (no Mono or .Net stuff) Uses Qt from TrollTech, Norway 65 languages GPL licensed Linus' favourite desktop :-) Mark Shuttleworth use KDE on his desktop (http://www.phoronix.com/scan.php?page=article&item=732&num=5)

What is KDE v3.5.7 latest stable (22/May/2007) v4.0 in development – offers completely new & exciting features Usability: Officially, KDE3 meets ISO9241 ( http://dot.kde.org/1179818755 ) My guess: More contributors from Europe, S.America

My guess: More contributors from Europe, S.America

KDE Structure for Dummies KDE CORE KDE Multimedia KDE LIBS KDE PIM Web Image and Video NON CORE KDE APPS, Non KDE Apps www.kde-apps.org KDE extra-gear OS, infra (dbus, hal) and libs (libpng, zlib,pcre, xine-lib etc)

KDE4 -Many new things strigi – fast search Phonon Audio Framework Solid – Hardware support visually appealing GUI kross scripting

KDE4 Will run (as expected) on many unixes, Linux, BSDs, and gasp... Windows and OSX too. KDE4-Alpha released: 11/May/07 Final release in Oct-2007 Build system uses cmake. Code hosted on svn QT available on Win & Mac -GPL Completely new architecture

KDE4 Phonon: MM API supports gstreamer, NMM, Helix, Xine, DirectX-Windows backends Better Accessibility, HIG conformance SVG rendering everywhere No more app names beginning with “k” -Big Relief :-) App cleanups and merging KDE3 compat libs to support old (kde3) apps (2011)

KDE4 Phonon Phonon is a new KDE technology that offers a consistent API to use audio or video within multimedia applications. The API is designed to be Qt-like, and as such, it offers KDE developers a familiar style of functionality Not a xine engine replacement Handles volume changes etc (eg: loud music+incoming voip call) http://dot.kde.org/1170773239/

KDE4 Solid After a lot of hacking behind the scenes, a new initiative to improve KDE's interaction with network and hardware devices has been launched. Solid will provide a robust basis for the dynamic modern desktop in KDE, which needs to be aware of available hardware and networks, paving the way for innovative functionality. Users should see KDE applications taking advantage of Solid in KDE 4, from the most basic Plasma applets and complex applications to desktop-wide awareness. Developers will be able to take advantage of a robust, flexible and portable API and will be integrated into the Plasma engine. It will make use of existing technologies like HAL. Solid will also include a knowledge base providing a way for users to easily provide feedback on incorrect behaviour. http://dot.kde.org/1136389547/

Some Myths Biggest Baddest: GNOME and KDE don't get along well : Nothing can be more wrong than this: eg Guademy 2007 (GUADEC + KDE Akademy) Work done at FD.o Common standards: dbus, scripting interfaces, HIG etc Many common underlying libs (okular uses poppler, xine-engine support in kde etc) There are major differences of opinions though
