Tiny Open Hardware Linux SBC Hides In Plain Sight

There was a time, not quite so long ago, when a computer was a beige box that sat on your desk. Before that, computers were big enough to double as desks, and even farther back, they took up a whole room. Today? Well today it’s complicated. Single-board computers (SBCs) like the Raspberry Pi put a full desktop experience in the palm of your hand, for a price that would have been unfathomable before the smartphone revolution increased demand for high-performance ARM chips.

But compared to the tiny open hardware Linux SBC that lives inside the WiFiWart, even the Raspberry

Build an open source-hardware Allwinner D1s RISC-V Linux SBC for under $10

We covered Allwinner D1s RISC-V processor with 64MB built-in RAM a few days ago, and we’ve just found out about Xassette-Asterisk, an open-source hardware board based on the processor that runs Linux (OpenWrt) and is said to cost less than $10 to make.

This is significantly cheaper than the Allwinner D1 based Nezha RISC-V Linux SBC currently sold for a little over $100, a rather poor value. The cheaper board will not quite have the same applications with just 64 MB RAM and no HDMI, but it could be great for projects requiring a camera and/or a display, audio

Linux To No Longer Enable AMD SME Usage By Default Due To Problems With Some Hardware

Being sent in as a fix for the Linux 5.15 kernel this morning and to be back-ported to existing stable series is a behavior change that the Linux kernel will no longer use AMD Secure Memory Encryption (SME) by default on supported hardware but rather making it now opt-in due to shortcomings of some platforms.

Since the introduction of AMD SME support to the Linux kernel, Secure Memory Encryption has been activated by default when the SME support (AMD_MEM_ENCRYPT) is built into the kernel. That defaulting of “AMD_MEM_ENCRYPT_ACTIVE_BY_DEFAULT” allowed for Secure Memory Encryption to be used out-of-the-box without needing to

AMD Finally Releases Overdue Linux CPPC Driver

As reported by Phoronix, AMD’s Zen 3 architecture is getting support for the ACPI CPPC driver designed for Linux-based operating systems. The Collaborative Processor Performance Control driver allows Linux to see which cores have the highest boosting potential in a Ryzen CPU and target the highest boosting cores for single- or lightly-threaded workloads, a feature that has been supported in Windows since the launch of the Zen 2 processors. Additionally, the ACPI driver will improve Linux’s support of Ryzen power states, allowing for better power consumption and performance. However, the new drivers are currently only for Zen 3, with

How to Install Linux on Any PC or Laptop

You’re considering Linux as a replacement operating system, but there’s a problem: you don’t know how to install it.

Switching to Linux can be straightforward. Choose a Linux operating system (OS), write the installation media, and sit back and wait. But while simple, it does come with some complications. Here, we look at how to put Linux on your PC with the minimum of fuss.

What You Need for Installing Linux

Elementary OS Linux

To install Linux on a computer or laptop, you will need:

  • A suitable target device (the PC or laptop) – note that installing Linux is destructive to existing data

How to Stress Test Your CPU in Linux

A key matrix for determining the vitality of a Linux distro, or the hardware that it runs on, is system performance. Depending on your purpose, you can choose from a variety of dedicated tools to monitor the different components such as CPU frequency, temperature and memory utilisation. But if you favour the CLI, like us, you’ll rather enjoy working with S-TUI.

With S-TUI, which is an acronym for Stress-Terminal UI, you can simultaneously monitor CPU temperature, frequency, power and utilisation. The utility presents all the information graphically and can even be used to  export the data into CSV files. Better

The best chat software for Linux, macOS and Windows isn’t Slack

Everyone chats. Everyone chats with different apps and services. But which is the best? You might be surprised at the conclusion Jack Wallen draws.

Finding the best chat software is a complicated mess. Why? Because everyone and every company uses a different service for team collaboration, messaging and even chatting with clients/customers. Some use Slack, others use Hangouts or Microsoft Teams. You might prefer Android Messages or iMessage. What about Twitter or Facebook messages?

How To Create a Multiboot USB Drive for Linux

There are hundreds, if not thousands of active Linux distributions and although many of the desktop distributions look the same, featuring the same set of applications or even desktop environments, there’s still a lot which separates them. This is why, for most novice Linux users, distro hopping – the practice of frequently switching between Linux distributions, is the only sane course to find one they’re comfortable with. Although many distributions now provide Live-installable images, making it possible to try the distribution without installing it first, constantly formatting USB drives to make room for the next distribution is quite cumbersome.

Linux Foundation Issues Frosty Final Judgment in UMN Scandal

The Linux Foundation Technical Advisory Board has released its findings regarding the University of Minnesota’s (UMN) contributions to the Linux kernel—including those related to the research projects that got the university banned from working on that kernel. The group also explained how the school might be able to earn some forgiveness, but it won’t be easy.

A quick refresher: In mid-April, the Linux developer who oversees the kernel’s stable channel, Greg Kroah-Hartman, banned the entire UMN system from contributing to the Linux kernel in response to a couple of the university’s research projects that centered on purposefully introducing faulty code

Banned UMN Researchers Apologize to Linux Community

University of Minnesota (UMN) assistant professor Kangjie Lu, along with graduate students Qiushi Wu and Aditya Pakki, apologized to the Linux community on Saturday for the controversial research into “hypocrite commits” that got the entire university system banned from contributing to the Linux kernel.

In an email to the Linux kernel mailing list, the trio said that the research in question, which sought to highlight one of the ways open source projects such as Linux can be undermined, was carried out in August 2020. The findings were published to GitHub on February 10; they didn’t appear to attract much attention
