There's much talk of the Open Source Sustainability Problem. From individual developers to Google's White House lobbying, the issue seems simple but intractable. Is the willingness of volunteer coders a solid enough basis for the long-term health of essential infrastructure?

Based on observed behaviour on Android and Chrome OS, Google began working on a new page reclamation strategy for its Linux-based OSes aimed to improve how the virtual memory subsystem reclaims unused memory pages. More recent work shows the new MGLRU policy can benefit server environments, too.

In this intro to our catalog of 136 Linux hacker boards, we examine how the 2021 chip shortage led to higher prices, limited availability, and more than twice the usual number of discontinuations. Yet, 29 models launched in 2021, including SBCs with M.2 slots, RISC-V CPUs, and AI chips.

The Linux kernel's frame-buffer device "FBDEV" subsystem has thankfully been on the decline over the past number of years thanks to the success of the more useful DRM/KMS drivers and having FBDEV compatibility emulation support. While not actively maintained, the FBDEV subsystem and some drivers remain within the Linux kernel and are used with some interest primarily in some legacy/embedded environments. The subsystem was orphaned while now a Linux kernel developer has stepped up to serve as its maintainer.

I recently moved into a new place, and discovered that my friend and I live in buildings that face each other. We’re about a kilometer apart, but both our balconies have line of sight to each other. I’ve always wanted to build a communications network with my friends since I was a kid, so I dusted off an old book about Morse, one of my Raspberry P’s and got to work. I’m a big fan of mixing old and new technologies, so instead of using something modern, I decided to use Morse code.

I've recently become a little obsessed with an online word puzzle game in which you have six attempts to guess a random five-letter word. The word changes every day, and you can only play once per day. After each guess, each of the letters in your guess is highlighted: gray means that letter does not appear in the mystery word, yellow means that letter appears in the word but not at that position, and green means the letter appears in the word at that correct position.

Cemu as one of the leading Nintendo Wii U video game emulators is planning to go open-source this year and is also working on Linux support and related cross-platform advancements.

If you're on Humble Bundle and use a Mac or a Linux computer, you may want to download all the games you can from the service's Trove before the month ends. Starting on February 1st, the Mac and Linux versions of the games in the Humble Trove will no longer available.

The new "SysJoker" backdoor can reportedly attack multiple operating systems, including macOS, Windows, and Linux. On January 11, researchers from Intezer revealed they had found SysJoker, a backdoor that was originally discovered to be attacking Linux. Shortly after, variants of the same backdoor were uncovered that went after Windows and macOS.

If you're using Ubuntu on WSL, did you know you can have a GUI package manager to use as well as the command line?

Canonical used to recommend Raspberry Pi 4 with at least 4GB RAM to run Ubuntu Desktop, but Ubuntu 22.04 LTS should run more smoothly on the Raspberry Pi 4 2GB as the company has enabled zswap by default to allow the Linux operating system to run better on systems with less memory.

Lots of people “run Linux” without really knowing or caring – many home routers, navigational aids, webcams and other IoT devices are based on it; the majority of the world’s mobile phones run a Linux-derived variant called Android; and many, if not most, of the ready-to-go cloud services out there rely on Linux to host your content.

Linux has many ways to install software. We can build our own executables or use AppImage to run containerized applications. But at the heart of many Linux distros is a package management system, which for Debian based systems, such as the Raspberry Pi and Ubuntu, is Apt.

Why small, single-board computers can be the future for smart working and small offices. With the pandemic changing the way we're working, job decentralization is becoming an important challenge for all companies.

Over the past decade there have been many Raspberry Pi clones. The latest clones the Raspberry Pi Zero form factor but introduces a RISC-V processor in place of the usual Arm powered SoC. MangoPi has appeared in a series of Twitter posts (as reported by Liliputing), and looks like a good choice for those needing more fruit in their diet.

This document takes you through the basics of intrusion detection, the steps necessary to configure a host to run the snort network intrusion detection system, testing its operation, and alerting you to possible intrusion events.

Researchers have uncovered a never-before-seen backdoor written from scratch for systems running Windows, macOS, or Linux that remained undetected by virtually all malware scanning engines.

Podman is an open-source tool for managing containers, images, volumes, and pods (group of containers). It's used the libpod library APIs for managing container lifecycles and supports multiple container image formats, including OCI (Open Container Initiative) and Docker images.

With a few notable exceptions, if you're looking for a new smartphone today you're pretty much limited to operating systems powered by Google or Apple. The PinePhone Pro flagship from Pine64 is a very different proposition, running Linux instead of Android or iOS.

RISC-V is the latest processor architecture to be enshrined in the Linux kernel, with mainline support for the StarFive JH7100 SoC coming in kernel version 5.17. The news, as reported by Phoronix, comes at the same time as the Snapdragon 8 Gen 1 chip from Qualcomm also makes its Linux kernel debut.
