I've had the Steam Deck for a week and it's been an absolute joy. Lots of folks have asked me questions about the software, in particular.
The ext4 filesystem with journal enabled, will write frequently to a flash stick, shortening its life. EasyOS image file has ext4 working-partition. Originally, it had the journal disabled; however, sometime early in 2020 I enabled the journal.
Rusty Aquarium is a utility that’s billed as a “monitoring visualization as an aquarium” software. The program should not be confused with traditional real-time systems monitoring tools such as top and other alternatives. This open source utility is written in Rust.
We need to utilize the text editor to take notes, write a program, or edit a system configuration file to get something done. Your Linux distribution already comes pre-installed with text editors, no matter the requirements. You will most likely notice some of the best modern text editors like Gedit, Geany, Kate, etc., pre-installed in your Linux distribution. However, these are all GUI-based programs.
Email is the bread and butter of electronic communication. It is simple, efficient and programmable. If you are looking for a desktop email client for Linux, there are many around. Here are some of the best email clients available for Linux.
Written in GTK and Python, System Monitoring Center is a powerful system performance and usage monitoring software that comes with a lot of unique and interesting features if you’re looking for a more complex system monitoring utility for your GNU/Linux desktop. The app comes with a more than generous graphical user interface that displays all sorts of details about your computer’s hardware and software, including but not limited to CPU, GPU, RAM, disk, network, processes, services, startup, system sensors, general system information, and users.
In this tutorial, we will show you how to install Varnish on AlmaLinux 8. For those of you who didn’t know, Varnish cache is an open-source, high-performance HTTP accelerator designed for speeding up web servers. Varnish exclusively focuses on HTTP as compared to other proxy servers which focus on FTP, SMTP, and other network protocols. It is purely designed to speed up caching of heavy dynamic websites. Varnish sits between Nginx and clients that receive requests from clients and forwards them to the backend. This will improve the webserver performance because Varnish will serve content from memory. 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 the step-by-step installation of the Varnish cache on AlmaLinux 8. You can follow the same instructions for CentOS and Rocky Linux.
Atom is a free and open-source text and source code editor that supports many cross-platforms such as macOS, Linux, and Microsoft Windows with support for plug-ins written in JavaScript and embedded Git Control, developed by GitHub. The catchphrase that Atom calls itself is the “hackable text editor for the 21st century”. Atom, compared to competitors, is more user-friendly, with plenty of options for extensions to add syntax highlighting for languages and formats, add dynamic linting, and integrate debuggers, runtime environments, video and music player controls, and much more. In the following tutorial, you will learn how to install Atom Text Editor on Ubuntu 22.04 LTS Jammy Jellyfish using the command line terminal and optional version builds of stable, beta, and nightly.
In this tutorial, we will show you how to install Hiri Email Client on Ubuntu 20.04 LTS. For those of you who didn’t know, Hiri is the best email client for Managers on Windows, macOS, and Linux. It allows us to have email, calendar, contacts, and tasks. Hiri is not free to use; however, you can enjoy 7 days trial period. Once the trial period is expired, you need to buy the Hiri subscription to keep using it. 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 the Hiri Email Client on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.
If you're an Android user, you probably use Google Messages to send and receive text messages on your device. But did you know you can also access Messages from your computer and chat with your contacts while sitting at your desk? Well, it's possible to do so, thanks to the device pairing feature on Messages. If you're wondering how to get it on your Linux desktop, it's possible using Google Messages for Desktop and Messages for Web. Let's take a look at using both of these methods to get Messages on your Linux desktop.
Ubuntu operating systems come with AppArmor, a Linux kernel security module that allows the system administrator to restrict programs’ capabilities with per-program profiles. Profiles can allow network access, raw socket access, and permission to read, write, or execute files on matching paths. Rhel family users would notice this is similar to Selinux; however, they work differently and have pros and cons. The following will cover how to enable and disable AppArmor and individual profiles on Ubuntu 22.04 LTS Jammy Jellyfish. Usually, most users would not need to adjust any settings with AppArmor, but if the need arises, some simple commands are all needed in the tutorial will explain.
Nmap, also known as Network Mapper, is a free, open-source tool network administrators use to scan for vulnerabilities within their network and network discovery. Nmap allows finding devices running on their network and discovering open ports and services that, if not secure or hardened, can lead to potential hackers exploiting known vulnerabilities security risks. In the following tutorial, you will learn how to install Nmap on Ubuntu 22.04 LTS Jammy Jellyfish desktop or server, along with some basic command examples to get you started before you know to use Nmap more thoroughly for users wanting to get more out of the scanner beside the standard port scan.
The VLC media player is an open-source, free portable, cross-platform media player software and streaming media server developed by the VideoLAN project. VLC can play nearly all known multimedia files and DVDs, Audio CDs, VCDs, and various streaming protocols and can be extended and customized with multiple plugins. In the following tutorial, you will learn how to install VLC Media Player on Ubuntu 22.04 LTS Jammy Jellyfish using three installations method of APT, Flatpak, and Snap.
In Linux, the change group or the chgrp command is mostly used to change the user group of the system. The chgrp command works for both Linux and other Unix-like operating systems. If you’re a system admin, you must already know that the chgrp, chmod, and chown commands are the most powerful and most used terminal commands. Conventionally, the chgrp command is run with the sudo or root privilege in the system, but if you’re the owner of that particular file or directory, you can execute the change group command as well. The most common usages of the change group command are installing a new package in the group, moving one file to another directory from the user group, and editing a non-read/writable file. This chgrp command can be very much handy and a life savior in critical situations.
DXVK 1.10 is here about five weeks after DXVK 1.9.4 with a plethora of performance improvements and fixes for some of your favorite games, including Age of Empires 2: Definitive Edition, Anno 1800, ArmA 2, Assassin’s Creed: Origins, Black Mesa, Elex II, Final Fantasy XIV, God of War, GTA IV, Nier Replicant, Quantum Break, Resident Evil 0, Resident Evil 5, Resident Evil 6, Resident Evil: Revelations 2, The Evil Within, and Total War: Warhammer III.
Two vital open source projects for the Steam Deck had new releases today, with the DXVK and VKD3D-Proton layers that translate Direct3D / DirectX to Vulkan. With these two, Proton that runs Windows games on the Steam Deck and Linux desktops should see some nice improvements with a future release. I won't go over all the changes, as it's aimed at quite a technical audience but for us regular users here's a few highlights.
Want to develop for the Steam Deck / SteamOS and get testing? Now it's a whole lot easier, as Valve has now put up the tools needed under open source licenses. There's two projects included with the SteamOS Devkit Client and the SteamOS Devkit Service, both of which are available on their GitLab page. Setting it up, at least on Linux, was pretty painless thanks to the clear instructions so even someone like me can give it a try and see what it's like.
One Deck Dungeon developer Handelabra Games Inc. announced recently that a new upgrade is available, which should make the experience on Steam Deck much nicer. "Adventure calls... but you don't always have time to spend hours optimizing your character sheet or managing your inventory! One Deck Dungeon lets you jump right in to bashing down doors, rolling dice, and squashing baddies with style. Get a full roguelike game experience, boiled down to its essence, and captured in a single deck of cards and a handful of dice! One Deck Dungeon is a dungeon crawling adventure game for one or two players."
XCOM 2 developer Firaxis Games has announced that the multiplayer modes are going to be shut down, if you're using the Windows version that is. In the support article, it notes "As a heads up to the XCOM 2 community, we wanted to share that we will be retiring services for Multiplayer and Challenge Mode for the Steam version of the game". Why? Resources (money): "The decision to retire these services isn’t something done lightly, but it does allow us to refocus our resources". Planned for March 28, it's a shame but there's an interesting silver lining here. If you run Linux, or the Steam Deck, you will still be able to play it online as it also mentions how "this won’t affect XCOM 2 on console platforms, or on Mac and Linux".
Traditionally, when people consider PC gaming, the overwhelming majority have only really considered Microsoft Windows as the operating system of choice. However, those thoughts are slowly changing, with Linux becoming more accepted. Experts at Steam published a hardware survey stating that more people are choosing Linux as the base for their PC gaming rig than ever before. The survey revealed that as many as 1.2 million active Linux users are currently on Steam, and that number is expected to continue to rise. Previously, gamers have strayed away from Linux mainly due to compatibility issues. Most games are only programmed to utilize the power of Direct X, which is only available on Windows. As a result, graphics card manufacturers focus their drivers on working seamlessly with Direct X, meaning that many of the games ported to work on Linux previously struggled to run as the developers intended, but that is something that is changing.
For when you are using Feral Interactive's GameMode and want some UI indication of its use.
Recently, I highlighted that Bungie gave a very clear no to Destiny 2 on Steam Deck. Seems a lot of people noticed and Bungie has issued an update — but it's still a no for now.
Just about a week after the Steam Deck formally released, we have officially hit over one thousand games that are either Steam Deck Verified or Playable. Quite a fun milestone that, however quality is better than quantity and there's been some rather curious titles that have been through verification recently.
As expected it did not take too long to reach this new milestone for the Steam Deck with more than 1000 games working on the device!
Steam Deck is already making waves to enhance the game support for the Linux platform. It runs on Steam OS 3.0 (based on Arch) and features KDE Plasma. Kudos to Valve for not locking down the platform and letting users experiment with it. While it is not available for everyone, it is an exciting piece of hardware challenging handheld Nintendo Switch.
The rapidly gaining popularity GNOME extension Just Perfection now has added support for the upcoming release of GNOME Shell 42. Just Perfection Extension helps you to make any changes to your GNOME Shell. You can change the visibility of almost all components of GNOME Shell, behavior tweaks and customize panels, and more.
This week was filled with good news surrounding openSUSE. On top of openSUSE Leap 15.4 reaching its beta build phase, rolling release Tumbleweed had six snapshots that updated a few networking packages and Leap 15.3 is putting out its second quarterly respin iso. The latest snapshot is 20220302. NetworkManager 1.36.0 reworked the handling of Layer 3 configurations that results in more robust behavior when addressing information from multiple sources (DHCP, manually configured, VPN) when applied simultaneously. Performance and memory should also slightly improve with the update. PipeWire 0.3.47 had a fix that removed infinite loops and the buffer size handling was fixed that made some applications stutter. Other packages to update in the snapshot were nftables 1.0.2, ruby3.1 3.1.1, xscreensaver 6.03 and a couple of Python Package Index version updates. Caching proxy squid 5.4.1 was updated in the 20220301 snapshot; the package had some code cleanup and made some visible developer changes. Window manager screen 4.9.0 eliminated a Common Vulnerability and Exposure that made a denial of service attack possible via a crafted UTF-8 character sequence; this was fixed by replacing the dropped combchar.diff. Other packags to update were autoyast2 4.4.32, yast2-trans and more.
Another week, filled with snapshots, is coming to an end. Tumbleweed has been rolling full speed ahead, bringing you 6 snapshots in 7 days (0225, 0226, 0227, 0228, 0301, and 0302).
This year’s openSUSE Conf will again be held at the Z-Bau in Nuremberg, from Friday, June 02 to Sunday, June 04. The Call for Proposals (CFP) is already open, and the submission period will close on April 14.
Do you dream of turning your hobby into a profession so that you can earn a living while doing work you enjoy? At first glance, this seems desirable. You work 40 hours a week (sometimes even a little more). Work takes up a large part of your life. It's nice to fill this time with an activity that gives you pleasure, like your favorite hobby. For example, if you enjoy building and maintaining your media server on your home network, you might want to translate that into a career as a sysadmin.

Huge financial incentives are commonplace in the skill-hungry tech sector as a way to acquire and retain scarce talent. However, compensation on its own is neither effective nor sustainable as a staffing tactic in the long term. It’s also wasteful. This is because most organizations have a ready pool of loyal workers who, with training and support, can be a fit for many tech jobs that are going unfilled today.
A successful digital transformation strategy involves more than just technology. It also requires empowering IT teams to move digital transformation forward. This means not only replacing on-premises servers with Internet services but adopting models that free up more space for technical professionals to work creatively. This adoption doesn’t always go smoothly. To avoid additional challenges, organizations should prioritize an approach that puts IT and technologists at the heart of the business, while empowering business leaders to understand how IT works.
In 2021, Ahmad Haghighi wrote about being erased from Fedora. Matthew Miller, Fedora Project Leader, didn't follow due process or give Haghighi any reason for erasure. He just vanished, as if one of Putin's vacuum bombs had been detonated under his computer. US sanctions against Iran don't prohibit voluntary and academic pursuits, they only restrict financial relationships. The only woman to ever win the Fields medal is the Iranian academic Maryam Mirzakhani. Stanford University had no problems employing her, would Matthew Miller exclude this brilliant foreigner from Fedora just as he excluded Haghighi? Other community members have made similar pleas for racial tolerance, for example, Justin Flory's blog on Red Hat and Iran. Nonetheless, if Red Hat, Fedora and Matthew Miller are taking this hard line on people born in Iran, shouldn't they show exactly the some rudeness to developers from Russia and Belarus today?
In the last few weeks the FIPS profile has become available for the Ubuntu Pro 20.04 images for AWS, Azure and Google Cloud Platform. The FIPS profile for Ubuntu 20.04 was already available on on premise environments through Ubuntu Advantage for Infrastructure. Ubuntu 20.04 FIPS includes cryptographic validated modules that enable organisations to run and develop applications for the US public sector and Federal government, including regulated industries such as healthcare and finance.
Renesas has launched its first RISC-V processor family with the RZ/Five general-purpose microprocessors based on an Andes AX45MP 64-Bit RISC-V CPU core, and with long-term Linux support via the industrial-grade CIP Linux that offers maintenance for over 10 years. The RISC-V processor is pin-to-pin compatible with the Arm Cortex-A55/M33–based RZ/G2UL processor family, and while being a general-purpose family, the RZ/Five chips are specifically well-suited to IoT endpoint devices such as gateways for solar inverters or home security systems.

It's my fourth Moziversary. It's been 4 years (and three days) now since I joined Mozilla as a Telemetry engineer. I joined Mozilla as a Firefox Telemetry Engineer in March 2018, I blogged three times already: 2019, 2020, 2021. The past year continued to be challenging. Except for a brief 3-week period the Berlin office stayed close, so we all continue to work from home. I haven't met (most of) my team mates in person since 2020. I hope that in 2022 I will have the chance to meet some of them again, maybe even all at once.
Snap! is a tool developed as a collaborative effort between UC, Berkeley, SAP, and various other institutions and used as the primary learning tool for students and adults using the BJC curriculum to learn the foundations of computer science.

Snap! is a visual, drag-and-drop programming language that is fully browser-based and features the ability to work with first-class data types (such as integers, variables, arguments, and arrays), procedures, and continuations. This enables Snap! to be powerful enough for a serious introduction to computer science while also allowing for high accessibility through its visual, drag-and-drop nature. Since Snap! is browser-based, learners can access it from any computer, phone, or tablet without purchasing or installing additional or specialized software.
Squish GUI Tester 7.0 is the first Squish edition to offer a unique new feature: video capture of test executions to debug and document tests. For a long time, it has been possible to capture screenshots of the desktop where AUT was running with Squish, whether automatically in case of a test failure or on-demand using API functions in scripting languages. While this helped users get an overview of the situation in AUT and on the desktop at the point of failure, it provided a rather static picture of the events.
Python program editors are designed to make it easier for programmers to write and debug their programs. We have discuss, top 5 best Python development tools (IDEs) and Code editors. A huge codebase may be easily managed and deployed quickly with the help of these Python IDEs. Desktop and web applications can be created using these editors. For continuous integration, developers are use following popular Python IDEs.
I have been working on data analysis for almost three years, and there are some starters that I think are essential for every data analyst using the popular Pandas library for Python. If you often do data transformations in Pandas, you know how annoying it can be to search the web for basic information every time you get started with a new dataframe. For me, one of those sore points is encoding text data. For some reason, I can never remember a good way to encode data when I need it. So, I decided to note down my three favorite ways of doing so. Let me know in the comments if you have any other alternatives.
The good news is that WCH shared the documentation on Github, but they did so in a weird way since they are just updating a zip file with all datasheet for CH34x chips as they get released, instead of having a directory, and commit new files or revision as they come by.
Researchers have found a major encryption flaw in 100 million Samsung Galaxy phones.
One cryptography expert said that ‘serious flaws’ in the way Samsung phones encrypt sensitive material, as revealed by academics, are ’embarrassingly bad.’ Samsung shipped an estimated 100 million smartphones with botched encryption, including models ranging from the 2017 Galaxy S8 on up to last year’s Galaxy S21. Researchers at Tel Aviv University found what they called “severe” cryptographic design flaws that could have let attackers siphon the devices’ hardware-based cryptographic keys: keys that unlock the treasure trove of security-critical data that’s found in smartphones.
Recently, the Qt Project's security team was made aware of an issue regarding Qt's usage of LoadLibrary in a few locations and determined it to be a security issue on Windows only.
The diffoscope maintainers are pleased to announce the release of diffoscope version 207. This version includes the following changes:
