It was just with Linux 5.15 last month that AMD added a new audio driver for Van Gogh APUs sporting an ACP 5.x audio co-processor (ACP) while now a new driver has been posted for Yellow Carp / Rembrandt with it introducing new ACP 6.x audio co-processor IP.
AMD engineers have been busy the past few months bringing up "Yellow Carp" under Linux that appears at this point to be the Linux codename for the forthcoming Ryzen 6000 series "Rembrandt" APUs. On top of all the graphics driver work and other Linux kernel driver support patches so far, new audio code came out on Monday morning.
The EROFS read-only file-system is adding LZMA compression support using a new header/container format called MicroLZMA.
This MicroLZMA format was developed in cooperation with XZ developer Lasse Collin to avoid wasting small amounts of space for headers. MicroLZMA also has possible use-cases outside of EROFS.
Linux block subsystem maintainer and IO_uring lead developer Jens Axboe continues making staggering optimizations to the kernel code to squeeze out the maximum performance potential out of his shiny new system.
After upgrading to an AMD Ryzen 9 5950X system for development and keeping to his Intel Optane Gen2 storage, he ended September being able to achieve around 5.1M IOPS per-core for this system he uses for reference testing and evaluation of Linux block subsystem changes. That 5.1M IOPS per-core is impressive while previously he was happy hitting above 3M IOPS per-core.
With Ubuntu 21.10 due for release this week I've been running various Ubuntu Linux performance comparisons across a variety of hardware and overall this new release is looking to be in great shape. One of the tests I recently carried out for curiosity is seeing how the AMD Zen 2 performance has evolved now over the past two years on Linux going from Ubuntu 19.10 to Ubuntu 21.10.
Geany is a code editor which uses GTK+ toolkit. The new version, Geany 1.38, comes with increased speed when opening documents.
Every developer who spends hours in front of a computer screen writing codes, absolutely needs an editor to program. Whether we want to program a web page, an application or a program, we must use a tool that allows us to edit the code, modify it and work with it.
Geany is a powerful, stable, and lightweight code editor with certain basic features of an Integrated Development Environment (IDE). It is an open source cross platform editor that is designed specifically for programmers thanks to its built-in support for over 50 programming languages. In addition, with Geany you can perform functions such as syntax highlighting and autocompletion.
Now that a new version has been announced, let’s see what has changed in Geany.
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.
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.
In this tutorial, we will show you how to install Cacti on Debian 11. For those of you who didn’t know, Cacti is one of the most popular open-source, web-based network monitoring and graphing tool that you can use to keep track of your network performance in almost real-time. You can also configure Cacti to poll SNMP devices, traffic counters, routers, servers, etc.
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step-by-step installation of Cacti monitoring on a Debian 11 (Bullseye).
DataDog is a famous, cross-platform service for monitoring various servers, services, databases, tools through a data analytics platform. Users can check available free space on RAM and disk or track the waiting period for web requests or CPU usage on their systems.
These issues might seem insignificant but they end up causing issues for servers with production applications that is why alerts are created to inform the stakeholder whenever the above mentioned events happen. In this article we’ll guide you how to create monitors using the DataDog tool and will create alerts to check on RAM usage and CPU usage.
This tutorial explains how to start, stop and restart services in Debian 11 Bullseye using both systemctl and service commands.
NGINX is an open-source, free HTTP server software. In addition to its HTTP server capabilities, NGINX can also function as a proxy server for e-mail (IMAP, POP3, and SMTP) and a reverse proxy and load balancer for HTTP, TCP, and UDP servers. The goal behind NGINX was to create the fastest web server around, and maintaining that excellence is still a central goal of the Nginx project. NGINX consistently beats Apache and other servers in benchmarks measuring web server performance and is now the most popular used web server according to W3Tech.
In the tutorial, you will learn how to install Nginx on AlmaLinux 8 with a free TLS/SSL certificate from Let’s Encrypt.
daloRADIUS on the other hand is an advanced web application for managing FreeRADIUS server. It supports various database backends such as MySQL, Sqlite, PostgreSQL, MsSQL, MySQL. It provides features such as Access Control Lists, support integration with Google Maps for geo-location of hotspots/access points, graphical reporting…
In this article, I am going to explain the basic usage of the Bash printf command with examples in Linux. By the end of this article, you will be comfortable in using the printf command in Bash shell scripting.
Ever heard of Homebrew? It’s a package manager with a very unusual feature. It allows ordinary users to install packages without using sudo, and it’s available for both macOS and Linux. While the tool on each of these systems is referred to as Homebrew, the Linux version installs as linuxbrew.
Once installed, users can use Homebrew via the brew command to install packages very easily. Installation of Homebrew itself, however, does generally require sudo privileges and installs in /home/linuxbrew.
The man page for the brew command calls it “The Missing Package Manager for macOS (or Linux)”.
Not too long after the initial Early Access release that was back in August, GrapeOcean Technologies has released a Linux version of their party-based RPG Black Geyser: Couriers of Darkness.
Inspired clearly by Baldur's Gate and Icewind Dale, the team are hoping to make their mark with challenging real time tactical combat with pause, deep lore and memorable companions, all set in a sprawling, unique fantasy world.
"As a small team, we wanted to create a unique world that had a different tone, but one filled with everything we’ve come to expect from a cRPG: an epic story, exploration, mystery and plenty of side quests," says David Zakal, Director and Founder of GrapeOcean Technologies.
Kathy Rain: Director's Cut has been confirmed by Clifftop Games and publisher Raw Fury to be releasing on October 26.
"Kathy Rain follows a burgeoning journalist as she investigates the mysterious death of her grandfather. Set during the age of laser discs and landlines in the 1990s, Kathy is armed only with her trusty motorcycle, a notepad, and her wits. Traveling all over her hometown of Conwell Springs, Kathy will uncover a local mystery that takes her on a tumultuous journey. What secrets are the people of this town hiding? Piece together the clues and follow the leads to discover the truth!"
Heroic Games Launcher has a fresh update released and it comes with some mighty fine new features, all in the name of making your Epic Store library easier to manage on Linux. All still unofficial of course, since the store doesn't support Linux directly.
With HGL version 1.10.1 it can now install parts of games that offer a selective download, you can run games using an "alternative" executable, available DLC will be listed along with a toggle to bring them all or not and you xan actually check the download / install size before installing games now.
With maps that advance and grow as you play through allowing you to place down more towers and change your tactics, Warstone TD from Battlecruiser Games is now available natively on Linux. The developer said that they're providing a Linux version now as "a lot people asked for it".
One feature that makes it quite interesting is how you place your towers. Initially you're not given a lot of stones to place defence down but more can appear as the level goes on and from defeating enemies, so eventually you get a lot more space to place your towers. There's also a class system to give you new abilities, plus the mission types are varied too that enables you to use other unit types. Quite a lot to like about this one and since release in 2018 it seems to have reviewed well from users on Steam.
A big celebration to be had for the folks working on ScummVM, the project that bundles together various game engines to allow you to play many older games easily on modern platforms. 20 years is a huge milestone for such a project, and it's a very important piece of open source tech for game preservation.

A bit later than planned — after a year and a half of isolation meeting people spreads really bad colds — we’re releasing the second beta of Krita 5.0.0! The same warnings we gave with beta 1 still hold! There are still some showstoppers, but there we’re also over 700 fixes closer to the final release.
This release also includes a reworked GPU accelerated canvas: especially on HiDPI screens and on macOS Krita should perform much better.
Krita 5.0 Beta 2 is out today as the newest test release for this very powerful, open-source digital painting program.
The first beta of Krita 5.0 came back in August with UI improvements and better performance along with supporting newer image formats, an all-new MyPaint brush engine, and a variety of other features.
Seasonal changes often trigger times of reflection. So does weathering the ups and downs of the COVID pandemic: We went from seeing no end in sight, to seeing the possible end of the pandemic, to “it’s complicated,” particularly with workforces distributed around the globe in different stages of quarantine.
Many leaders and their teams have gone from in-office work to 100 percent remote work to a mix of both with hybrid work. Meanwhile, the job market has become so hot that some are calling it the Great Resignation. In the public sector, many employees who have been eligible for retirement for years are now accelerating their retirement plans.
As time goes on, we’re seeing that a Great Resignation is really an outcome of what is being called the Great Reprioritization, in which employees are pausing to reflect and reprioritize what’s most meaningful to them personally and professionally.
Our team members are reprioritizing based on meaning and purpose, and we need to help them on that journey if we want to keep them.
For business leaders who have ever struggled with whether or not to embrace digital transformation, the pandemic made that decision easier. Just as nobody predicted COVID-19, nobody anticipated the changes it would bring to organizations across all industries.
Organizations that were not prepared for the sudden pause in operations and subsequent challenges – including limited in-person contact, remote working, and paper-based processes digitally – struggled to survive. Meanwhile, digital organizations were able to adapt to the changing requirements with speed and agility.
The pandemic not only made enterprises realize the importance of planning for the unexpected, but it also made a strong case for accelerating digital transformation. It left no room for the excuses that some business leaders used to delay their technology investments.
Firefox 93 is out, though because of inopportune scheduling at my workplace I haven't had much time to do much of anything other than $DAYJOB for the past week or so. (Cue Bill Lumbergh.) Chief amongst its features is AVIF image support (from the AV1 codec), additional PDF forms support, blocking HTTP downloads from HTTPS sites, new DOM/CSS/HTML support (including datetime-local), and most controversially Firefox Suggest, which I personally disabled since it gets in the way. I appreciate Mozilla trying to diversify its income streams, but I'd rather we could just donate directly to the browser's development rather than generally to Mozilla.
Want to learn more about developing applications with Quarkus? Download our free e-book Quarkus for Spring Developers, which helps Java developers familiar with Spring make a quick and easy transition.
Microservice applications designed today are often deployed on a platform such as Kubernetes. This platform can orchestrate the deployment and management of containerized microservices. Microservices development calls for sophisticated patterns, such as health checks, fault tolerance, load balancing, distributed tracing, and remote debugging and development. Because of this, it is essential to adopt technologies and frameworks that support these patterns while also providing a great developer experience.
This article will discuss some of these patterns and showcase why Quarkus is ideal for Kubernetes-native Java applications.
Red Hat OpenShift Service Registry is a fully hosted and managed service that provides an API and schema registry for microservices. OpenShift Service Registry makes it easy for development teams to publish, discover, and reuse APIs and schemas.
Well-defined API and schema definitions are essential to delivering robust microservice and event streaming architectures. Development teams can use a registry to manage these artifacts in various formats, including OpenAPI, AsyncAPI, Apache Avro, Protocol Buffers, and more. Data producers and consumers can then use the artifacts to validate and serialize or deserialize data.
This article gets you started with OpenShift Service Registry. You’ll create a Quarkus-based Java application that uses the registry to manage schemas for data sent through topics in an Apache Kafka cluster. The tutorial should take less than 30 minutes, and involves the following steps...
The latest versions of Red Hat Software Collections and Red Hat Developer Toolset for Red Hat Enterprise Linux 7 are available now in beta.

We’ve covered plenty of AMD Ryzen Embedded V2000 SBCs in the past, but it appears IBASE IB952 might be the first 3.5-inch SBC with a Ryzen V2000 processor for the industrial and IoT markets.
The board supports up to 64GB RAM, offers two SATA III ports for storage, dual Gigabit Ethernet networking, four display outputs with DisplayPort, eDP and LVDS interfaces, USB and serial ports, as well as expansion through two M.2 sockets.
M5Stack UnitV2 is an ultra-compact Linux AI camera powered on Sigmastar SSD202D SoC with a dual-core Cortex-A7 processor @ 1.2 GHz, and 128MB on-chip DDR3 that was launched in April 2021 with a Full HD camera featuring a 68€° field-of-view.
M5Stack has now introduced two new models, one called M5Stack UnitV2 USB without any camera at all, instead relying on an external USB UVC camera, and the other named M5Stack UnitV2 M12 equipped with an M12 socket and shipping with both a normal focal length camera with an 85€° FoV and wide-angle focal length with a 150€° FoV.
We missed you the last couple of weeks so it’s a bumper issue today. Our big news is the launch of raspberrypi.com: we have a super new website where we hope you’ll find it easy to get to all you need to know about Raspberry Pi computers and our other products. Continue to find free resources, coding clubs, and educational support from the Raspberry Pi Foundation at raspberrypi.org.
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.
Many question in the automation world comes, the most question that comes up a lot more than any question is which tool should I use to automate my processes?
The answer depends on what you are trying to do? But in general IFTTT is more for personal stuff and Zapier is more for business.
With IFTTT, we have got the Alexa devices, speakers, and light bulbs fully automated.
However, Zapier's helps you to connect your apps and automate workflows and data exchange among these apps. As an example, automate your posts to Twitter and Facebook or even automate your Instagram process (posts, likes, comments).

The few experienced developers in these areas are working for big companies and under strict contracts, non competes and NDAs, so it's very difficult for them to lend a hand even if they wanted.
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.
The Qt Sensors module provides access to sensor devices such as accelerometer and gyroscope. The logical architecture separates the concrete sensor types (“accelerometer”) from the platforms providing them (“Android”). This is illustrated by the Figure below:
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.
Researchers at Northwestern University is moving the goalposts on how small you can make a tiny flying object down to 0.5 mm, effectively creating flying microchips. Although “falling with style” is probably a more accurate description.
Patching database software is often a real pain-in-the-rump. The reason? Easy. When you need to patch one, it almost always requires a reboot. That takes time, sometimes a lot of time. So, so matter when you time it, your users will not be happy. Now TuxCare has an answer: DatabaseCare. This live patching service for the most popular open-source enterprise-grade databases, MySQL, MariaDB, and PostgreSQL enables you to patch database management systems (DBMS) with no downtime.
According to researchers from cybersecurity firm ESET, the malware, named FontOnLake, appears to be well-designed and while under active development already includes remote access options, credential theft features, and is able to initialize proxy servers.
FontOnLake samples first appeared on VirusTotal in May 2020 but the command-and-control (C2) servers linked to these files are disabled, which the researchers say may be due to the uploads.
To respect “privacy and human dignity,” MEPs said that EU lawmakers should pass a permanent ban on the automated recognition of individuals in public spaces, saying citizens should only be monitored when suspected of a crime.
The parliament has also called for a ban on the use of private facial recognition databases — such as the controversial AI system created by U.S. startup Clearview (also already in use by some police forces in Europe) — and said predictive policing based on behavioural data should also be outlawed.
MEPs also want to ban social scoring systems which seek to rate the trustworthiness of citizens based on their behaviour or personality.
In a recent YouTube video ad, a man named Sergei Dalivelia sits on a wooden chair, his hands tied behind his back. He looks straight to camera and, in a shaky voice, apologizes for criticizing the government of Belarus and President Alexander Lukashenko. “I posted offensive comments online,” he said. “I very much regret this. I regret that I wrote this without thinking.” Clicking on the ad took the viewer to a pro-government Telegram channel titled Zheltye Slivy.
