What politics can teach us about open source

Friday 13th of September 2019 04:13:55 PM

The Roman Empire ended in a dictatorship, while the feudal Middle Ages delivered the Magna Carta and the Renaissance; despite the American Revolution, slavery continued for many years, while the French Revolution resulted in the restoration of the monarchy. That said, more people are living in democracies around the world today than at any time before, and living standards in democracies continue to improve.read more

Thursday 12th of September 2019 10:53:11 PM
Providing meaningful metrics for open-source projects has long been a challenge, as simply measuring downloads, commits, or GitHub stars typically doesn't say much about the health or diversity of a project. It's a challenge the Linux Foundation's Community Health Analytics Open Source Software (CHAOSS) project is looking to help solve. At the 2019 Open Source Summit North America (OSSNA), Matt Germonprez, one of the founding members of CHAOSS, outlined what the group is currently doing and why its initial efforts didn't work out as expected.

SQLAlchemy is a Python ORM toolkit that provides access to SQL databases using Python.

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 organization says that the new SBC fills the gap between small Raspberry Pi-like computers and more powerful desktop machines. 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
