Linus Torvalds Switched Back To Gnome

Posted on in Categories Gnome, Kde, Linux, Linux desktop, Linux distribution, Linux laptop last updated January 24, 2009

Linus Torvalds, Linux’s creator, dislikes the GNOME desktop. There was a big flame war(s) between Linus Torvalds and the GNOME community. At one point he claimed that – “Gnome seems to be developed by interface Nazis and that its developers believe their users are idiots“. And guess what? Who made the switch to Gnome?

Nokia To Add LGPL Option For the Qt UI and Application Framework

Posted on in Categories Kde, Linux, Linux desktop, OS X, UNIX, Windows, windows vista, X server last updated January 14, 2009

Good news for all developers! QT will be available under the LGPL starting with version 4.5. The GNU Lesser General Public License (LGPL) is a free software license published by the Free Software Foundation. The LGPL places copyleft restrictions on the program itself but does not apply these restrictions to other software that merely links with the program. There are, however, certain other restrictions on this software. The LGPL is primarily used for software libraries, although it is also used by some stand-alone applications, most notably Mozilla and OpenOffice.org.

This option could increase Qt usage and adoption. You may see more cross platform commercial application on the Linux desktop. This is huge news for cross-platform developers.

New Notification System for GNOME and KDE

Posted on in Categories Gnome, Kde, Linux desktop, News last updated December 24, 2008

Canonical the makers of Ubuntu about to introduce a new desktop notification system proposal. New changes should improve the usability of the Linux desktop including desktop notification system for both GNOME and KDE. From the Mark Shuttleworth blog:

The key proposals we are making are that:

* There should be no actions on notifications.
* Notifications should not be displayed synchronously, but may be queued. Our implementation of the notification display daemon will display only one notification at a time, others may do it differently.

That’s pretty much it. There are some subtleties and variations, but these are the key changes we are proposing, and which we will explore in a netbook device with a partner, as well as in the general Ubuntu 9.04 release, schedule gods being willing.

I think new changes looks more like Growl system used in Mac OS X. You can read more about proposal including mockup video that shows new notification system here.

Qt To Be Licensed Under GPL version 3

Posted on in Categories GNU/Open source, Kde, Linux, News last updated January 19, 2008

Qt is the standard framework for high performance, cross-platform application development. Trolltech ASA is licensing its Qt cross-platform development framework under the GNU General Public License version 3 (GPL v3), with immediate effect. GNU founder Richard Stallman said:

I am very pleased that Trolltech has decided to make Qt avaliable under GPL v3. This will allow parts of KDE to adopt GPL v3 too. Even better, Trolltech has made provisions for a smooth migration to future GPL versions if it approves of them.

Qt is already available under the GPL v2 and will continue to be so in addition to the GPL v3.

The GPL v3 license will make it easy and safe for free software developers to use Trolltech’s Qt with the most recent license framework from the Free Software Foundation. Trolltech hopes that its move will inspire free software projects to use GPL v3 when programming with Qt.

Download of the day: Dolphin File Manager for KDE Linux Desktop

Posted on in Categories Debian Linux, Download of the day, Kde, Linux, Linux desktop, Ubuntu Linux last updated November 21, 2007

Dolphin is a file manager for KDE focusing on usability. The KDE 3 version of Dolphin is in beta stage, but provides already most features for daily usage. Currently Dolphin gets ported for KDE 4.0. I really liked its simplicity.

The main features of Dolphin are:

* Navigation bar for URLs, which allows to navigate quickly through the file hierarchy.

* View properties are remembered for each folder.

* Split of views is supported.

* Network transparency.

* Undo/redo functionality.

* Renaming of a variable number of selected items in one step and much more

Download of the day: Dolphin File Manager for KDE Linux Desktop Picture

Install dolphin

Debian / Ubuntu Linux user, type:
$ sudo apt-get install dolphin

To start dolphin start KDE or type:
$ dolphin &

From the man page:

dolphin is not intended to be a competitor to Konqueror, the default KDE file manager: Konqueror acts as universal viewer being able to show HTML pages, text documents, directories and a lot more, whereas dolphin focuses on being only a file manager. This approach allows to optimize the user interface for the task of file management.
