Switch to KDE 4.2.2

Filed under
Linux

My main home production machine has been PCLinuxOS based for some time. Since PCLOS doesn't yet support KDE 4, I had to change distros. What would be more natural than installing PCLOS's foundational parent, Mandriva? Mandriva has a full complement of KDE 4 (and Gnome) applications, and the KDE 4 stuff is the latest 4.4.2. So I backed-up the home partition of my production box to an external hard disk drive, and installed Mandriva Spring 2009 RC 2 over PCLOS.

One thing driving my switch is the desire to do some C++ and Python development with the Qt 4.5 tools, and Mandriva's Spring 2009 RC2 includes those tools, all nicely integrated.

So, am I happy? In a word, yes. With the Desktop "Folder Containment view", things behave much like the old KDE, so I can get around fairly well, and do what I need to do. And, as Mandriva is building toward their final Spring release, they are releasing daily scads of bugfixes and updates--resulting in my system now becoming very stable, which is essential for a production machine. I'm going to (for comparison purposes) try Kubuntu Jaunty Jackalope on my experimental machine, as it too uses KDE 4.4.2 and is at release candidate status. While I've been a harsh critic of the 'buntus (mostly toward newbie 'buntu users and 'buntu users who act as if 'buntu IS Linux), it's time I took another look at 'ubuntu.

With Mandrive Spring 2009 RC2, I had some initial trouble with sound. I finally installed all the Xine stuff, told KDE 4.4.2 to use Xine rather than GStreamer as the back end, disabled Pulseaudio--and now sound works fine.

So far, so good.

Following the trend of privacy-respecting products and projects coming out of Europe (e.g., ownCloud, Kolab, and Plasma Mobile), German firm struktur AG has started a Kickstarter project called Spreedbox, which aims to offer a secure audio video conferencing service. According to the project page, “The Spreedbox is a unique device for secure audio/video conferencing, text and video messaging and file sharing. The Spreedbox is your own conferencing, meeting and file exchange service on the Internet and puts the control and security of your data into your own hands.” Read more

Student researchers collaborate virtually with help of open-source software

A typical summer research program—the institute's Nanobio Research Experience for Undergraduates, for example—brings students together to one host university, where they work in different laboratories on various projects. In the new pilot training program on Computational Biomolecular, students use an open-source software called Rosetta to work together on problems in computational biology and are mentored by faculty who are part of a global collaborative team known as the Rossetta Commons. The software gives users the ability to analyze massive amounts of data to predict the structure of real and imagined proteins, enzymes, and other molecular structures. Read more

Open Source Is Going Even More Open—Because It Has To

Open source foundations are nothing new. Linux Foundation has been around since 2007, and other major projects like the Eclipse code editing tool and the Apache web server have been governed this way for even longer. Many of the most important open source projects in recent years, such as the Hadoop big data crunching platform and the database system Cassandra, are managed by the Apache Foundation. But it’s unusual to see so many new foundations created so quickly. Read more
