How Linux came to the mainframe

Thursday 12th of September 2019 11:44:10 AM
Despite my 15 years of experience in the Linux infrastructure space, if you had asked me a year ago what a mainframe was, I'd be hard-pressed to give a satisfying technical answer. I was surprised to learn that the entire time I'd been toiling away on x86 machines in various systems administration roles, Linux was running on the s390x architecture for mainframes. In fact, 2019 marks 20 years of IBM's involvement in Linux on the mainframe, with purely community efforts predating that by a year.read more

Introduction to the Linux chgrp and newgrp commands

In a recent article, I introduced the chown command, which is used for modifying ownership of files on systems. Recall that ownership is the combination of the user and group assigned to an object. The chgrp and newgrp commands provide additional help for managing files that need to maintain group ownership. It is important to understand how to manage users, groups, and permissions. It is also good to know a few alternative ways to work around problems you might encounter since not all environments are set up the same way. Read more

Linux-Powered BeagleBoard AI Comes With Debian Out-of-the-box

Linux-powered BeabgleBoard AI Single Board Computer (SBC) has been launched by the BeagleBoard foundation at a $125 price tag. The new SBC runs Debian GNU/Linux out of the box.

The BeagleBoard AI was shown way back in February 2019 and now it has finally been launched. In my experience, Beagleboard computers are really awesome devices. We have even included the original Beagleboard, the Beagleboard Black and the X15 on our list of “Best Raspberry-Pi Alternatives.” Read more

Redcore Linux 1908 LXQt

Redcore is a Gentoo-based project which strives to make it easy to install the distribution and immediately have access to a pre-configured desktop environment. Redcore is available in two editions, KDE Plasma and LXQt, and offers builds for 64-bit (x86_64) machines exclusively. The latest version of Redcore Linux has shifted from using Gentoo's Stable branch as its upstream source to Gentoo Testing. Software now flows from Gentoo Testing, into Redcore's Testing repository, and then into Redcore Stable where most Redcore users will access it. The Redcore ISO files are relatively large with both editions being 3.4GB downloads. Given the similarities in size, I decided to try the LXQt edition. Booting from the Redcore media brings up a graphical login screen with a mostly-white background. We can sign into the live desktop using the username and password "redcore". The default wallpaper is mostly white with abstract lines. The combination makes for a bright screen populated with harsh lines that I personally found unpleasant and I soon switch to another background. There are two icons on the LXQt desktop. One opens the Calamares installer and the other is labelled "Ask for help". Clicking the latter icon causes LXQt to pop-up an error saying the selected icon is an invalid desktop entry file. Clicking the installer icon brings up a prompt asking if we would like to open or execute the installer's desktop file. Along the bottom of the screen we find a panel containing the application menu, task switcher and system tray. Read more
