Study the Elements with KDE's Kalzium

I've written about a number of chemistry packages in the past and all of the computational chemistry that you can do in a Linux environment. But, what is fundamental to chemistry? Why, the elements, of course. So in this article, I focus on how you can learn more about the elements that make up everything around you with Kalzium. KDE's Kalzium is kind of like a periodic table on steroids. Not only does it have information on each of the elements, it also has extra functionality to do other types of calculations.

Plotting on Linux with KmPlot

This issue of Linux Journal marks the magazine's 25th anniversary. So, I thought I'd look back to see when I wrote my first article, and I was horrified to see that it was in 2000. I'm too young to have been writing articles for more than 18 years! Here's to another 25 years for Linux Journal and all of the authors who have made it what it is.

FOSS Project Spotlight: Nitrux, a Linux Distribution with a Focus on AppImages and Atomic Upgrades

Nitrux is a Linux distribution with a focus on portable, application formats like AppImages. Nitrux uses KDE Plasma 5 and KDE Applications, and it also uses our in-house software suite Nomad Desktop. What Can You Use Nitrux For? Well, just about anything! You can surf the internet, word-process, send email, create spreadsheets, listen to music, watch movies, chat, play games, code, do photo editing, create content—whatever you want!

A Look at KDE's KAlgebra

Many of the programs I've covered in the past have have been desktop-environment-agnostic—all they required was some sort of graphical display running. This article looks at one of the programs available in the KDE desktop environment, KAlgebra. You can use your distribution's package management system to install it, or you can use Discover, KDE's package manager. After it's installed, you can start it from the command line or the launch menu. When you first start KAlgebra, you get a blank slate to start doing calculations.

Astronomy on KDE

I recently switched to KDE and Plasma as my main desktop environment, so I thought I'd start digging into some of the scientific software available on KDE. First up is KStars, the desktop astronomy program. KStars probably won't be installed with the standard KDE desktop, so you may need to install it. If you're using a Debian-based distribution, you can install KStars with the following command:

Astronomy for KDE

Although I have covered a large number of science applications in the past, I haven't really looked at too many options available within the KDE desktop environment. This has been due to my own biases in using a GTK-based desktop environment, but now I'd like to look at some of the packages available for people who really like to use KDE on their own machines.

Linus Ditches KDE and Gnome (so what?)

Having made an earlier defection from KDE to Gnome, Linus Torvalds has now rejected both in favor of Xfce. It’s only natural that the actions of the creator of the Linux kernel would attract extra scrutiny, and I think that his decision is reflective of a wider disenchantment amongst long-term Linux users.

Kde 4.7 Released And In The Wild

July saw the release of KDE SC 4.7. Like all recent KDE releases, this is a combination of updates to the bundled applications, underlying desktop and associated technologies. Canonical have already pushed 4.7 through to Kubuntu desktops.

KDE4: It hurt, but did it work?

Last month's release of the KDE 4.4 desktop environment restored the faith of many after what has been something of a roller coaster two years. Even the most loyal KDEians found that loyalty stretched by the debut of version 4.0 in 2008. Reassessing, and with hindsight, I think it's fair to characterize the whole saga as both a cautionary tale and an admirable example.
