Raspberry Pi CM4 Used in Custom Nintendo Switch Lite Replica

Filed under
GNU
Linux
Hardware

The small form factor and processing power of the Raspberry Pi CM4 has made it a go-to choice for many developers looking to create custom handheld consoles. Today we’ve got another impressive CM4-powered handheld to share, this one created by maker known as StonedEdge. After a year of designing and building, they and a friend have managed to create a Nintendo Switch Lite replica featuring a CM4 that runs RetroPie called the RetroLite CM4.

As of right now, the project is not open source, but the makers have taken it under consideration for the future. Until then, curious parties are still welcome to get a close look at the build process and internal components should they seek to create something similar of their own.

  • How to Check if Hardware RAID is Configured on Linux Server

    Hardware RAID is configured on the physical servers, which use a dedicated RAID controller to manage the raid configuration.

    The RAID controller manages and performs all RAID-related tasks independently of the OS. What I am saying is that it does not take any resources from the operating system to perform raid related tasks.

    RAID stands for Redundant Array of Inexpensive Disks. It combines multiple physical hard disk drives into one or more logical drive to improve performance and reliability.

    In this guide, we’ll show you how to check hardware RAID configured on HP ProLiant servers from Linux.

  • Building a Retro Linux Gaming Computer - Part 7: The Arena Eternal | GamingOnLinux

    When I was growing up, one of my first exposures to Linux was my father’s stack of old Linux Journal magazines. Printed in several of these was one of many advertisements by the Linux server company Penguin Computing, this one depicting Linux mascot Tux brandishing a rocket launcher in the iconic Q3DM7 map included in the demo version of Quake III Arena. This image became so emblematic of Linux as a gaming platform that it still gets widely circulated to this day.

    When I switched to using Linux full time in the spring of 2007 one of my first accomplishments was getting that same demo to install. I remember being frustrated at not having it work on first launch, until I discovered I had to copy my system's libGL.so.1 file to the install directory, one last caveat brought on by the need to support both 3dfx as well as more generic OpenGL accelerator hardware. From that moment on, my Linux box became a gaming machine.

    It was not until later that I would discover the full effect Quake III Arena had on the Linux ecosystem by downloading and playing the numerous derivative games created from the 2005 source code release available in almost all Linux software repositories. Even with all of those other options it was the original game I always found myself coming back to, with my main listed frag count now exceeding 21,000 frags as of the time of this writing.

  • Book of Travels is a thoroughly strange take on an online RPG now in Early Access | GamingOnLinux

    Might and Delight has just released Book of Travels, an online RPG played they're calling a "TMORPG" meaning Tiny Multiplayer Online RPG and it's quite something. Note: personal purchase.

    The idea is that instead of joining a server with thousands of people, you're given a world where you might come across a few others instead but not too many. Right now the total per server is only seven people, so you're lucky if you even see anyone and in a way it makes it a bit more exciting. Compared with other online RPGs, it's a much more solitary experience and one you can quite easily relax in.

  • Clean up your Git repository with this Linux tool | Enable Sysadmin

    Git is an amazing tool for tracking all your changes and reverting them if necessary. While Git is perfect, people are not. So, if you send something by mistake to your repo, like a build file, temporary folder, your cache, and so forth, Git will store it because it can't predict when you make mistakes.

    You can, of course, remove files with the git rm command. Git will remove the file but keep it available in case you need it later. However, if you do this often enough, you end up with what I call a bloated Git repository. It isn't enough to clean up your repo; you also need to remove sensitive files that you could accidentally send to someone.

  • Translators team: Reaching more people in their native language

    Since the founding of the organisation in 2001 the FSFE's translators team has been an important part of the FSFE. The translations made by the translators team have enabled people all across Europe to learn and read about software freedom and the FSFE's mission to empower users to control technology. Translations from English to another language enable people who are not fluent in English to read, learn, and participate in Free Software. Without the help of our translators team, this would not have been possible.

    For the last 20 years the FSFE's translators team has been working on translating the FSFE's statements, news items, activities, campaigns, and background information. The first translation for our website, which is today no longer available on the website, was made in 2001 by translating the "Volunteers welcome" text to French. Later the "Volunteers welcome" text became our contribute page. In 2004, with the move from gnu.org to our own infrastructure, the then translation coordinator, Reinhard Müller, launched the first general information page about the translators team and the translation process. Since then a lot has happened.

  • A Simple OpenPGP API

    In this post I want to share how easy it is to use OpenPGP using the Stateless OpenPGP Protocol (SOP).

    I talked about the SOP specification and its purpose and benefits already in past blog posts. This time I want to give some in-depth examples of how the API can be used in your application.

    There are SOP API implementations available in different languages like Java and Rust. They have in common, that they are based around the Stateless OpenPGP Command Line Specification, so they are very similar in form and function.

    For Java-based systems, the SOP API was defined in the sop-java library. This module merely contains interface definitions. It is up to the user to choose a library that provides an implementation for those interfaces. Currently the only known implementation is pgpainless-sop based on PGPainless.

  • Linux for Starters: Your Guide to Linux – Running VirtualBox - Part 20 - LinuxLinks

    This is a series that offers a gentle introduction to Linux for newcomers.

    In computing, virtualization refers to the act of creating a virtual version of something, including virtual computer hardware platforms, storage devices, and computer network resources.

    We will walk you through setting up a virtual machine running openSUSE. The words host and guest distinguish the software running on the machine from the software that runs on the virtual machine. For the purpose of this article, the host machine is running Ubuntu, the guest machine is openSUSE.

    Software like VirtualBox allocates parts of the CPU, RAM, storage disk, and other components so that a virtual machine can use them to run properly. The virtual OS thinks that it’s running on a real system, but it runs just like any other program on your computer.

    VirtualBox has a wide variety of uses. For a newcomer to Linux it lets them test a variety of different distros without messing up their existing setup. Think of the operating system running in a safe, sandboxed environment,.

    With virtualization, you want as much RAM as possible, as you need RAM for the host operating system and the guest(s) operating systems. While 8GB is sufficient for many desktop uses, it’s insufficient for virtualization. We only recommend using VirtualBox if your machine has more than 8GB of RAM. The faster and more powerful your PC, the more that virtualization offers.

  • Arduino Becomes Superhet With A Little Help From Friends | Hackaday

    A radio receiver is always a fun project. [Jayakody2000lk] decided that his new superheterodyne design would use an Arduino and it looks like it came out very nicely. The system has four boards. An off-the-shelf Arduino, a Si5351 clock generator board (also off-the-shelf), and two custom boards that contain the IF amplifier and mixer.

    The receiver started out in 2015 without the Arduino, and there’s a link in the post to that original design. Using the Si5351 and the Arduino replaces the original local oscillator and their have been other improvements, as well. You can see a video about the receiver below.

    Tuning is by a rotary encoder and the current software lets you tune from about 4.75 MHz to a little over 15.8 MHz. Of course, you could change to any frequency the Si5351 can handle as long as the mixer and other components can handle it. The IF frequency is the usual 455 kHz.

  • Security Risks of Client-Side Scanning

    Even before Apple made their announcement, law enforcement shifted their battle for back doors to client-side scanning. The idea is that they wouldn’t touch the cryptography, but instead eavesdrop on communications and systems before encryption or after decryption. It’s not a cryptographic back door, but it still a back door — and brings with it all the insecurities of a back door. I’m part of a group of cryptographers that has just published a paper discussing the security risks of such a system. (It’s substantially the same group that wrote a similar paper about key escrow in 1997, and other “exceptional access” proposals in 2015. We seem to have to do this every decade or so.) In our paper, we examine both the efficacy of such a system and its potential security failures, and conclude that it’s a really bad idea.

It provides a smart, fully equipped, and user-friendly command-line environment for all Linux users. Fish shell supports various features unlike any other shell such as autosuggestion, Tab completion, syntax highlighting, Sane Scripting, Glorious VGA Color, and web-based configuration. Using this interactive shell environment, you do not need to remember a bunch of Linux commands because it is more productive and comes with various handy features. We will talk about the installation of interactive Fish Shell on CentOS 8 in this tutorial. The same steps apply to Rocky Linux and AlmaLinux too.

  • How to disable Special keys Windows 10 (Sticky keys) | ITIGIC - TechStony

    They are keys that exist since the first versions of Windows and continue in the most recent versions, including Windows 10. Therefore, we are going to tell you what the special keys or Sticky Keys consist of and how to deactivate them because you have already tired of having them in your computer (or because they hinder you).

  • How to install Devuan(II) - Unixcop

    In this article I show how to install Devuan using the installer included in the desktop-live iso, refractainstaller. In a previous article I’ve showed how to install it using the net-install ISO. From the devuan site: Devuan GNU+Linux is a fork of Debian without systemd that allows users to reclaim control over their system by avoiding unnecessary entanglements and ensuring Init Freedom.

  • How to install and configure NextCloud on Centos 8 and LEMP

    In this guide, we are going to set up NextCloud on a Centos 8 server hosted with Nginx and php (LEMP stack). We will be using Mysql 8 and PHP 7.4 for this guide.This will also work for RHEL derivatives like Alma Linux 8, Rocky Linux 8 and RHEL 8. Nextcloud is an Open Source suite of client-server software for creating and using file hosting services. It is a a free self-hosted cloud storage solution similar to Dropbox, Google Drive, etc. With Nextcloud, you don’t have to worry about the pricey alternatives and since you will host your own files, you don’t have to worry about privacy or someone collecting your data.

Kernel: Paul E. Mc Kenney and New Stuff in Linux

  • Paul E. Mc Kenney: TL;DR: Memory-Model Recommendations for Rusting the Linux Kernel

    These recommendations assume that the initial Linux-kernel targets for Rust developers are device drivers that do not have unusual performance and scalability requirements, meaning that wrappering of small C-language functions is tolerable. (Please note that most device drivers fit into this category.) It also assumes that the main goal is to reduce memory-safety bugs, although other bugs might be addressed as well. Or, Murphy being Murphy, created as well. But that is a risk in all software development, not just Rust in the Linux kernel. Those interested in getting Rust into Linux-kernel device drivers sooner rather than later should look at the short-term recommendations, while those interested in extending Rust's (and, for that matter, C's) concurrency capabilities might be more interested in the long-term recommendations.

  • Cluster Scheduler Support Queued Ahead Of Linux 5.16 - Phoronix

    Cluster scheduler support has been queued up for landing in the Linux 5.16 kernel for AArch64 and x86_64 systems for improving the CPU scheduler behavior for systems that have clusters of CPU cores. The cluster scheduler support in this context is about enhancing the Linux kernel's scheduler for systems where sets of CPU cores share an L2 cache or other mid-level caches/resources. This cluster scheduler work stems from work by HiSilicon and Huawei aiming to improve the Linux performance for the Kunpeng 920 server chip. That HiSilicon SoC has six or eight clusters per NUMA node with four CPU cores per cluster and a shared L3 cache. With the cluster scheduler patches they were able to enhance the overall performance of the system and also improve the efficiency.

  • AMD Finally Enabling PSR By Default For Newer Hardware With Linux 5.16 - Phoronix

    With it getting late into the Linux 5.15 kernel cycle, the focus is shifting by the Direct Rendering Driver maintainers from new feature work targeting the next cycle (5.16) to instead on bug fixes. AMD sent out a pull request of new AMDGPU Linux 5.16 material this week that is primarily delivering bug fixes but one notable addition is finally enabling PSR by default for newer GPUs.
