Palm Bliss: An old product of my interest
in themes and templates

UITE often I rave about KDE, as I last did a week or so ago. However, I admit that GNOME is beautiful too, so I have collected a few themes and previews which support its beauty.

• Gentle Gnome mockup
• Glass Icons Theme
• nuoveXT
• Avio-GDM

Lastly, here is a way of making GNOME look more like Mac OS X. I don’t necessarily endorse or praise, but I just love the looks of Apple hardware and software. KDE is able to achieve similar results, I might as well add.

An example of less innovative KDE themes: Baghira Mac OS X lookalike

ESTERDAY I took a quick tour through some mockups and proposal made for the KDE project. I would like to present three examples, which are merely screenshots, sometimes combined with art work.

• Navigation Bar Reloaded
• Korganizer better integration
• KBFX 0.5 (One of the mockups)

As these ideas were contributed and voted on by the community of users, no doubt KDE will remain at the forefront of functionality and user experience. It’s a case of programmers preparing and eating their own dogfood, so to speak.

am exceedingly impressed by the innovative work of the KDE team. These folks truly invent some productivity methodologies which exist nowhere else. KDE is primarily targetted at operating systems such as Linux and BSD and it puts them both at the forefront of innovation. How they do it, I don’t know, but I suspect that requests and suggestions from the public (KDE userbase) make it a reality, via wishlist items, reported as ‘bugs’ with low severity level. Allow me to exemplify my statement using a timely realisation.

Only yesterday, I needed to restart KDE (no reboots involved). This happened after over one month of this non-stop KDE session. The motive? Possibly a few memory leaks, which had accumulated throughout 5 weeks of 24/7 computing (I run experiments using untested code overnight and whenever I am absent). Either way, once restarted, KDE restores the user’s session perfectly.

All windows re-appear in the correct virtual desktop, in the same position with the same dimensions as prior to logout. A complete system reboot would have had the same impact. Shells are reinstantiated and created, possibly positioned at the same directory/path as before. While it sounds simple and trivial, it is not. File managers likewise. FTP connections are restored with the servers in question, even at the right depth and directory level. The only exception are SSH connections that were opened without calling the command directly, e.g. SSH within a shell. Otherwise, even remote connections as such are restored! Again, this should not be taken for granted.

In this older version of KDE (3.1, as haven’t tested it yet with the newer setup at home), Mozilla applications are the sole exception. They are not being restored. Nonetheless and all in all, well done, KDE team! You thought of everything the user will ever need.

There is a Mozilla Firefox extension called SessionSaver. It achieves something similar to the above by fully restoring tabs, even with textarea input re-instered. This mechanism is robust and even resilient to browser crashes, all at the expense of browsing performance, as well as some system resources.

ESTERDAY I read about three-dimensional displays, which are said to require no glasses and make stereo-vision a reality. This seemed like ‘queue hopping’ from a scientific point-of-view, so I had to read it carefully and identify some points of skepticism. I was successful in finding some gaps and deficiencies, which a careful read would quickly reveal (albeit the headline is very eye-catching — an exaggeration within or even beyond reason).

MAGINE to yourself a world (or a desktop environment rather) where everything lies in 3-D space. Imagine interaction with objects, which takes into account the ‘depth’ Z of one’s arm, rather than just the (X,Y) coordinates — those that are delivered from the conventional mouse.

Croquet is an intersting project that provides an SDK for 3-D environment. It could potentially make it all a reality. Pseudo-3d (stereo imaging) displays exist already.

SING virtualisation software, someone from Hungary illustrates how Mac OS X, Linux, and Windows can be worked on simultaneously (view screenshot and further details), without the need to boot into a different, independent partition.

This comes only a week or so after Boot Camp from Apple began supporing Linux. It now caters for Linux boots, as well as Windows boots. It relies on the availability of Intel chips, which replaced Power PC in an important strategic move. This makes the prediction and vision of triple-boot machines a reality, but moreover, it does so without the obvious perils. It obviates the need to reboot Mac OS X. This equips Apple with a huge selling point.
