A Look at Trolltech and Qt 4

Two recent articles cover the success of Trolltech and their product Qt 4, on which KDE 4 will be based. 'Trolltech: A case study in open source business' looks at the continued growth of the company based on dual licenced Free Software. The article describes what KDE and Trolltech gain from each other, including user feedback to Trolltech and sponsored developers for KDE. The Australian Computerworld declares that Qt 4 raises the bar for cross-platform app dev tools. They cover the separate modules of Qt 4 and the cross-platform quality, giving it a 9.2 out of 10 approval rating.

Interview: Fiorini of the Mockup Project

Pier Luigi Fiorini is the lead developer of Mockup. Mockup is an open source effort to create a modern desktop operating system. It is based on Linux 2.6 and supports native POSIX threading, hardware detection, automatic device creation and automatic network configuration. The user interface, written using Qt 4, runs on Xorg, but will also support the framebuffer in future versions. Read on for an interview.

New Blog on Qt Affairs

"Welcome to A Qt Blog. This is a blog I intend to feature announcements on developments in the Qt world: Qt itself, applications, publications, devices, as well as KDE, KDE-centred operating systems (particularly Linux distributions), and Trolltech affairs. I'd also like to have the occasional review and feature article on development and other topics."

Qt, the GPL, Business and Freedom

In a series of articles (part I, part II) during the month of July, OfB's Timothy R. Butler explained why he felt that KDE needed to move beyond the Qt toolkit it uses as a foundation. In that series, he asserted that the licensing of Qt is becoming a stumbling block to the desktop's adoption. Eric Laffoon, the project lead for KDE's Kdewebdev module, takes exception to Butler's arguments and makes the case for his view on the issue of Qt at OfB.biz.
