KDE 4.3.0 Caizen Released

4 08 2009

Today the KDE community announced the released of their 4.3.0 desktop environment, codenamed Caizen.

If you don’t know KDE you should give it a peek because, either you like the philosophy behind or not, the project is important and daring.

As I mentioned before KDE is a desktop environment. It’s commonly related to the Kubuntu official derivation of Ubuntu Linux and other Linux distributions in general, but the environment can be installed also on Windows and Mac.

kde430-desktopThe main purpose of the KDE community is that of providing a strongly integrated, easy to use and stunningly stylish desktop. This is pursued not just by a pure aesthetic work but by a strong effort to propose and follow a their own concept of human-machine interface. The stress is always on the integration of the applications with the desktop composed of a stylish layout and sleek objects seen as track leading to simplicity and tidiness. The desktop is completely composed by widgets which float over the surface like objects on a table. Unlike a table however you can’t just drop a file onto the surface, the way you would with any other desktop environment, but you must place them inside a dedicated desktop widget. This can be frustrating at the beginning but after a while you will likely find the desktop widget easy to use, intuitive and helpful in driving you to keep your monitor free from the mess.

A strong asset of KDE is that it’s built on Qt libraries which is an extremely powerful and modern UI and application framework (probably the best). For this reason all a series of features, like graphics, graphical effects, etc.. are comparable to those found on Mac OSX and far better than those implemented in Vista, with the surplus of working smoothly even on my 4 years old average end laptop.

Unfortunately but physiological given the youth and ambition of the project, KDE suffered of many bugs during its life. However the community behind KDE is strong and the bug solving process did not lag behind. With the 4.3.0 version they claim the “community fixed over 10,000 bugs and implemented almost 2,000 feature requests in the last 6 months“.

How I messed up my laptop with Kubuntu 8.10 KDE 4.2

18 03 2009

I’m a Linux user since Ubuntu 7.10 “Gutsy Gibbons”, then we can say I’m quite a freshman.

I took the decision to migrate my XP laptop to Linux mostly because I wanted to sail new waters after being a MS user since MS-DOS 5.0.

Until now I must say that my experience was pretty positive. I had no major problems switching to a new system. I found substitutes for most of the software I was used to and for those few I didn’t find an alternative, I relied on VirtualBox OSE and my old XP home edition. I was quite impressed by the stability and safety of the system. My laptop and me experienced a new speed we weren’t accustomed to. The only thing made me a bit crazy was the impossibility to run the composite manager with application based on OpenGL or which worked with video rendering (basically Google Earth and VLC for watching videos). I understood that this was because of my ATI video card yet I was disappointed by the fact that the situation remained always the same either with Hardy and lately with Intrepid.

With the advent of the 8.10 “Intrepid Ibex” release I decided to try again something new and switched to the Kubuntu fork. At the beginning I felt both dizzy and bewildered by the KDE4 environment. It took me some times to get somewhat accustomed to the new desktop manager which sets a complete new concept of user interface. The learning curve wasn’t so flat but I judged the worth the effort. On the other face of the coin the stability of the system was terrible. Panels got messed up once in a while causing me to swear first and sweat after to get everything in place. Contextual menu were sometimes weird (I couldn’t open a pdf from the web on the fly but was forced to download and open it after), the ark tool won’t compress -it didn’t see them- some kind of files (like pdf) and folders, trying to erase a file caused the system to drain an insane amount of resources without apparent reason (but pressing shift+canc didn’t), etc… With KDE4.2 version things im proved quite much and this was a great relief. However something dark was coming

Out of the blue the headphones just stopped working. The weird was that by inserting the jack I got the feed for about one sec and then all went silent. After searching forums I did understand that the problem was probably related to ALSA and they advised to uninstall it and recompile. You know how it is when you happen to have an uncommon problem; the resources are few and often contrasting. As I said I’m a freshman and what is worse, a freshman without the time and will to learn bash and compiling and stuff the way I used to enjoy with MS-DOS when I was a teen. So I did what I usually do when I don’t know where to slam my head against what in Linux. I opened Adept and looked for ALSA related package. And I had the great idea to uninstall one package (probably libasound-2, or alsa-base). The computer crashed and I was forced to restart. Guess what it happened when I tried to access to my user session again? See below…

Then I got scared. The computer was full of documents, all expendable except the fact I had a big bunch of new pictures of my son I didn’t backuped. I was cold sweating and already thinking of my wife chasing me down like Sauron with the Fellowship of the Ring, except I wasn’t likely to make it… I accessed my user from console to try to backup the pictures directory by cp-ing it to the external drive. But I could find the external drive in the /media directory and all my attempts to mount it were a failure. At this point I booted from the live cd and managed to have access to the folder and copy it to a safe location. At least I managed to sleep that night…

The day after (which is two days ago) I wiped the hard disk and installed Ubuntu 8.10 which is now running onto my laptop. I enjoy a immediate feel of improved stability and boosted speed. However the headphones problem keeps on haunting me!

I’ve grown loving Linux but there are things that really piss me off. I worship over all the concept of ergonomics and elegance in all human manufactured products, so also for what concerns software. In their way the distros I used are ergonomic and elegant but there are a few things I can’t stand. Installing new software is a completely insane process. Left behind the add/remove tool, all what remains is chaos. Sometimes you just download a software from a website, double click and it installs and goes into the right place of the menu (Truecryp on Ubuntu). Sometimes you download it and then you must go and search for instructions to install it, copy&paste those on the terminal and that’s it (Google Earth) but then how you uninstall it?? Sometimes you must add the repositories and, if you’re lucky, the software get installed without issues and goes in the right menu place. Some other times you must mess with bash to copy files to some root place with sudo etc… As far as I’m concerned this is something crazy and one of the things which keeps new user at bay from say Ubuntu. Nowadays many people are willing and able to search the internet for open source alternative software, but how many of them can or want to the same to learn how to install it? Again, let’s be frank, apart from the add/remove and, in a shorter range, synaptic, tool it needs a super user to install software on Ubuntu.

Anyway I could stand all this installation matter and bound to let’s time be my teacher. The headphones trouble is though something completely unacceptable. We’re speaking of a pretty basic function and a priority one. I will probably take my time and try some solution in a protected environment like VirtualBox but again this takes time and to me it’s really a pain in the rear to waste a lot of time trying to solve this headphones related issue!

I won’t surely go back to Windows, but I’m looking forward an iMac as my next computer.





KDE Developer interview

7 02 2009

Since I switched from GNOME to KDE (at the time of the migration from Hardy to Intrepid) my relationship with this desktop manager has always been quite likely to one with a woman. There’s passion, bewilderment but also disappointment and sometimes frustration.

kde421Despite this exciting relation, I must admit that KDE is leaping on the curve of stability and usability.
KDE4.1 was very buggy and frustrating but with the fresh new 4.2 version lots of things have greatly improved.
I’ve never used KDE3 but no one can deny the fact that it took a lot of courage, not speaking of sense of the vision, to jump to this revolutionary version of the desktop manager. It’s like KDE wants to say “I can do and look better than OSX!” Maybe today we’re not too far from the target…

Part of this is thanks to the Qt library. Despite Trolltech (now Nokia) creature is not so beloved inside the open source community because of its license limitation (which I deem unfair given that the restrictions apply to the commercial software), it has the pros to be really powerful and good looking.

Anyway, by checking the KDE web site I spot this interesting interview of Dario Freddi, a KDE developer and fellow Italian, so I thought to give it a plug here.

Here below it’s just an excerpt, you can find the complete interview in English here, and in Italian here.

———————– enjoy

Observing your “conversion on the way to Damascus” I ask you what you like of the other Desktop Managers and if you feel that KDE is missing something in respect to them.

Dario: Bearing in mind that the only ones I have actively used for some time are Enlightenment E17 and GNOME, I won’t express much on E17. I tried it some time ago, and still today I give it the credit of pushing me to learn the command line, because it was in an early stage of developement at that time. I would like to give it a try today, especially because of the good things they are doing (we’ll be able to create plasmoids with QEdje in KDE 4.2), and I’m sure I’ll do it when I’ll
have time.

Regarding GNOME, it’s a difficult question, but the answer is, honestly, that I think that KDE doesn’t miss anything that GNOME has. On the contrary, I think that the idea that “GNOME is more usable” is partly wrong because, in this area, KDE is gaining ground. KDE has improved a lot regarding usability and rationalisation of the user interfaces, which was some time ago
GNOME’s strong point. We should give credit of this change to the organisation of the community, where there are people working exclusively on these aspects. You can tell me I’m coloured, but at the time being (and I’m talking about KDE 4.2), KDE doesn’t have anything to envy GNOME (after all, if I have been converted and I didn’t get back there should be a reason! :D ).
