One fascinating session (and one that shows how FOSSCamp works and why it's so productive) was given by Mirco Müller, who discussed using OpenGL in GTK applications.

ZK is an AJAX toolkit designed to make creating user interfaces that run in a Web browser as simple as creating event-driven interfaces for desktop applications. The interfaces created with ZK use an XML markup language to define the user interface and Java code to implement the Web application's functionality.

The KDE Community is proud to announce KDE Frameworks 5.0. Frameworks 5 is the next generation of KDE libraries, modularized and optimized for easy integration in Qt applications. The Frameworks offer a wide variety of commonly needed functionality in mature, peer reviewed and well tested libraries with friendly licensing terms.

The 4.7 release will bring a number of exciting improvements: KWin, Plasma's window manager now supports OpenGL-ES 2.0, improving performance and deployability on mobile devices. Dolphin, KDE's flexible file manager has seen user interface improvements and now sports a better user experience for searching in files' metadata. KDM, KDE's login manager now interfaces with the Grub2 bootloader.

One of the most innovative and simultaneously controversial features of KDE 4 is the Plasma widget, Folderview. Simply put, it allows a user to display the contents of a file system folder within a widget on the desktop.

Last November we detailed the Wayland Display Server, which came about as a lightweight alternative to the X.Org Server and leveraged the latest Linux graphics technologies (primarily kernel mode-setting), and is designed elegantly with the rendering and compositing all being done by Wayland.

Qt 4.7 has not been released yet, but the curious can download the beta or even grab a snapshot from git. The big news in this point seven release is Qt Quick - a new approach to user interfaces. Before I get carried away and start throwing screenshots at you, let's step back and look at today's user interfaces.

At FOSSCamp in October, skilled eye-candy expert Mirco Müller (also known as MacSlow) hosted a session about using OpenGL in GTK to bring richer user interfaces to desktop Linux applications.

The KDE Community is proud to announce a Tech Preview of KDE Frameworks 5. Frameworks 5 is the result of almost three years of work to plan, modularize, review and port the set of libraries previously known as KDElibs or KDE Platform 4 into a set of Qt Addons with well-defined dependencies and abilities, ready for Qt 5.
