Docker has several standalone alternatives, some of which offer virtualization technologies and cross-platform support. Docker alternatives that stand out are also Open Container Initiative (OCI) tools that work with Docker, replace some Docker components, or work with other Docker alternatives to form robust Docker competitors.
Thanks to its contemporary tools, compatibility, sizable community, and simplicity of use, Docker is still relevant for the majority of container projects, apps, and developers today. The licensing for Docker Desktop has recently changed, among other modifications made by Docker Inc. Consider these Docker alternatives that stand out in 2023 if you’re worried about the future of Docker and the exponential growth of Kubernetes because there are probably yet more changes to come. In this article, we’ll discuss the top Docker alternatives that stand out in 2023.
The latest Linux Saloon went off without a hitch, from a technical perspective. No issues during the streaming process, the bitrate was stable, OBS worked without issues and Zoom was crash free. It was a great way to start off the New Year. Of course, I did mess up the very beginning by forgetting to unmute the audio sources within OBS so an updated checklist is in order when I get the show started in the future
Continued support was added to the AMDGPU and AMDKFD code work as part of the support for DRM-Next. The new pull request is going to be added to the AMD Radeon graphics driver for Linux 6.3 kernel. Alex Deucher of AMD submitted the new request last Friday, following the patches that were sent in by Mario Limonciello from AMD.
2022 really passed by fast and after I completed the GSoC 2022, I’m now completing another milestone: my project in the Igalia Coding Experience and I had the best experience during those four months. I learned tremendously about the Linux graphics stack and now I can say for sure that I would love to keep working in the DRM community.
While GSoC was, for me, an experience to get a better understanding of what open source is, Igalia CE was an opportunity for me to mature my knowledge of technical concepts.
So, this is a summary report of my journey at the Igalia CE.
After 8 months of work by Yinon Burgansky, libinput now has a new pointer acceleration profile: the "custom" profile. This profile allows users to tweak the exact response of their device based on their input speed.
A short primer: the pointer acceleration profile is a function that multiplies the incoming deltas with a given factor F, so that your input delta (x, y) becomes (Fx, Fy). How this is done is specific to the profile, libinput's existing profiles had either a flat factor or an adaptive factor that roughly resembles what Xorg used to have, see the libinput documentation for the details. The adaptive curve however has a fixed behaviour, all a user could do was scale the curve up/down, but not actually adjust the curve.
Needless to say h264/5 weren't my real goals in life for video decoding. Lynne and myself decided to see what we could do to drive AV1 decode forward by creating our own extensions called VK_MESA_video_decode_av1. This is a radv only extension so far, and may expose some peculiarities of AMD hardware/firmware.
With the standardization of the Vulkan decoding extension less than a month ago, two codecs were defined - H264 and H265. While they have cemented their position in multimedia, another, newer codec called AV1 appeared. Indeed, I was involved with its standardization. Not entirely satisfied with the pace of Khronos, nor with VAAPI's lack of synchronization, me and Dave Airlie decided to make our own extension to support AV1 decoding - VK_MESA_video_decode_av1. We were granted an official dedicated stable extension number from Khronos, 510, to avoid incompatibilities.

In this tutorial, we will show you how to install Varnish on Ubuntu 22.04 LTS. For those of you who didn’t know, Varnish is an open-source, high-performance HTTP accelerator that is used to improve the performance and scalability of web applications. It is a reverse proxy that sits in front of a web server and caches static content, such as HTML, CSS, and JavaScript files. By caching this content, Varnish reduces the workload of the web server and speeds up the delivery of content to users. Varnish offers many features such as private CDN, Gzip compression and decompression, HTTP streaming pass & fetch, 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 the step-by-step installation of the Varnish cache on Ubuntu 22.04 (Jammy Jellyfish). You can follow the same instructions for Ubuntu 22.04 and any other Debian-based distribution like Linux Mint, Elementary OS, Pop!_OS, and more as well.

Here learn about the shell which is an important part of the Linux operating system. The shell in the Linux operating system is used as a command line interpreter. It works between user input and Linux Kernel.
Here learn how to sort a file based on the contents of multiple columns in Linux. The sort command provides a lot of options that allow you to customize the way it sorts your data.
Here learn how to rename multiple directories in Linux at once. To do with multiple directories, we need to use special commands, scripts, or a combination of different commands.
EPEL (Extra Packages for Enterprise Linux) is a community-driven project that provides additional software packages for Enterprise Linux distributions such as CentOS, Red Hat Enterprise Linux (RHEL), and Scientific Linux. These packages are built and maintained by a group of volunteers and are compatible with the corresponding version of the Enterprise Linux distribution.
The lastlog command in Linux shows the most recent login of all the users or a specific user by pulling the information from the “/var/log/lastlog” file.
The output is a long format summary of all the user’s account names, ports, IP addresses, and last login timestamps.
Also, don’t confuse this tool with the last command, as both are separate tools and give you different information by reading different database files.
In this article, you will learn how to use the lastlog command on Linux to check the most recent login of all users or a specific user, as well as how to clear a single or all user’s last login records.
The alias command in Linux is used to create and manage aliases, which are essentially shortcuts for longer commands.
Here learn how to rename a Linux directory whose names contain special characters such as space. We will make use of quotation marks, escape characters, and a couple of alternative methods to handle it.
Learn about one of the most useful Bash command, source, which is used to execute commands from a file or script in the current shell environment.
In this tutorial, we learn how to use userdel command in Linux to remove a user. A system administrator might require to remove a user when the user account is compromised, user no longer required, or when the user itself creates problems.
Here explore the sort command in more detail, including how to use it to sort data in various ways and how to customize the sort using options.
Here learn how to rename a directory in Linux from the terminal. Renaming a directory in Linux can be a useful way to keep your file system organized and maintainable.
While I pay for multiple video streaming services, I never got on board with streaming music services such as Amazon Prime Music or Spotify. I’ve curated quite the collection of MP3s in the past twenty years, with a fair number of tracks that aren’t available through streaming services. Since most phone manufactures have stolen our beloved SD card expansion slots, I’ve had to rely on various services the past few years to enjoy my music on the go.
This started with Amazon Music, when there was an option to pay for a given amount of storage that you could upload your music collection to and enjoy through the Amazon Music app on your mobile devices. Then came Google Play Music with a similar service, but then Google did what Google does and killed that product in favor of Youtube Music. Ugh.
I’ve since moved on to hosting a Plex server on a Raspberry Pi in my home’s network rack. Rather than loading my substantial music collection on the same SD card that the operating system runs on, I’ve opted to connect a 2.5” SSD with a bountiful amount of storage to the Raspberry Pi via USB. From here, I’m able to stream my music anywhere I have an internet connection through the surprisingly great Plexamp app.
We wrote an article a few days ago about the tuptime command, which is used to view the historical and statistical records of the uptime command.
In this article, we will discuss another similar utility named uprecords, which is used to record and keep track of Linux system uptime during every session.
The output of this command gives a summary of historical uptime records, like how long the system has been up on each session, the highest uptime, when the system has been rebooted, etc.
Stick with this article to learn each and everything about this tool using its options (with practical examples).
GIMP, short for GNU Image Manipulation Program, is a free and open-source image editing software that can be used on Linux Mint and other operating systems. It is a powerful tool that can be used for a variety of tasks, such as photo editing, graphic design, and creating digital art. It offers many features that make it a suitable alternative to expensive professional software, such as Adobe Photoshop. Incorporating GIMP into your daily Linux Mint desktop can bring many benefits, including enhancing and manipulating images, creating custom graphics, and saving money on expensive software.
Git is a widely-used version control system that tracks software development project changes. It allows multiple developers to work on a project simultaneously while keeping a record of all changes made to the code. Incorporating Git into your daily CentOS Stream desktop can bring many benefits, including collaborating with other developers, keeping track of changes made to your code, and quickly reverting to previous versions of your code.
The Linux cat command is one of the most versatile tools that can use to create files, view them, and even combine them in the Linux command line.
In this article, we take a detour and explore how you can join two text files in Linux using the cat command, (short for “concatenate”) is one of the most commonly used commands in Linux as well as other UNIX-like operating systems, used to concatenate files and print on the standard output.
It is not only used to view files but can also be used to create files together with the redirection character.
Everyone looks back fondly on the days we played classic games like Sega, PlayStation One, and Nintendo. But with today’s powerful PCs and smartphones revolutionizing technology beyond what anyone imagined in those times, it’s no surprise that retro consoles are slowly becoming obsolete. If you’re yearning to recapture those childhood gaming days again, then you’ll be glad to know that developers have created powerful emulator systems which make it possible. Linux users can now relive their nostalgia through these emulators — and in this guide, our goal is to provide the best retro game experience available!
As you generate and store more data in your digital systems, the need for seamless access to that data across multiple locations becomes increasingly important. This is where Network Attached Storage (NAS) comes in.
It's the end of an era. As The Reg covered last week, IBM has transferred development of AIX to India. Why should IBM pay for an expensive US-based team to maintain its own proprietary flavor of official Unix when it paid 34 billion bucks for its own FOSS flavor in Red Hat?
Here at The Reg FOSS desk, we've felt this was coming ever since we reported that Big Blue was launching new POWER servers which didn't support AIX – already nearly eight years ago. Even if it was visibly coming over the horizon, this is a significant event: AIX is the last proprietary Unix which was in active development, and constitutes four of the 10 entries in the official Open Group list.
Within Oracle, Solaris is in maintenance mode. Almost exactly six year ago, we reported that the next major release, Solaris 12, had disappeared from Oracle's roadmap. HPE's HP-UX is also in maintenance mode because there's no new hardware to run it on. Itanium really is dead now and at the end that's all HP-UX could run on. It's over a decade since we reported that HP investigated but canceled an effort to port it to x86-64.
The last incarnation of the SCO Group, Xinuos, is still around and offers not one but two proprietary UNIX variants: SCO OpenServer, descended from SCO Xenix, and UnixWare, descended from Novell's Unix. We note that OpenServer 10, a more modern OS based on FreeBSD 10, has disappeared from Xinuos's homepage. It's worth pointing out that the SCO Group was the company formerly known as Caldera, and isn't the same SCO as the Santa Cruz Operation which co-created Xenix with Microsoft in the 1980s.
It’s time to start thinking about Test Days for Fedora Linux 38. A Test Day is an event aimed getting interested users and developers together to test a specific feature or area of the distribution. You can run a Test Day on just about anything for which it would be useful to do some fairly focused testing in ‘real time’ with a group of testers; it doesn’t have to be code. For instance, we often run Test Days for localization and internationalization topics.
From continued supply chain concerns to challenges related to edge and AI/ML adoption, here are the top security trends to watch in the coming year
Digital transformation is now cemented into mainstream vernacular, but it is far from fully understood. Contrary to what you might glean from software marketing pamphlets, installing a new technological system is not the solution to your organization’s biggest problems. Successful digital transformation initiatives are not centered on the technology itself but on the people they serve.
Developers should test their Python code with multiple Python versions. Fedora and tox make this task easier, even for many non-Fedora systems.

Hackerboards.com single board computer database has been around for several years starting as Board-DB, but I noticed another one called FindBoard while browsing on Aliexpress with some more exotic boards.
Hackerboards’ database currently features 467 SBCs and MCU boards, while FindBoard has 453 boards. There are some overlaps, but also boards that are not found in the first database.
Many of the boards on FindBoard are Linux-capable, but they are also some microcontroller boards as we can see from the screenshot above. If Chinese is selected, the “Buy now” will redirect you to Taobao, and if it is English they will be a link to an Aliexpress page.

Elephant Robotics ultraArm P340 is a robot arm with an Arduino-compatible ATMega2560 control board with a 340mm working radius whose arm can be attached with different accessories for drawing, laser engraving, and grabbing objects.
We’ve previously written and reviewed the myCobot 280 Pi robotic arm with a built-in Raspberry Pi 4 SBC, but the lower-cost ultraArm P340 works a little differently since it only contains the electronics for controlling the servos and attachments, and needs to be connected to a host computer running Windows or a Raspberry Pi over USB.
I've written a review of the Android 13 upgrade on my Nokia X10 smartphone, covering new look and feel, somewhat degraded usability efficiency, unchanged privacy setup, per-app language configuration, significantly improved performance and battery life, botched QR code scanner, some other observations, and more. Take a look.
About one-third of Firefox users have installed an add-on before – whether it’s an extension to add powerful and customizable features or a visual theme to personalize the web browsing experience. But if you’re unfamiliar, add-ons are sort of like apps for your browser. They can add all kinds of features to Firefox to make browsing faster, safer or just more fun.
The past year introduced some exciting new changes to the extensions world. The majority of these changes are foundational and take place in the deeply technical back-end of the system, typically out of sight of most Firefox users. However, if you pride yourself on hanging out in popular cybersecurity hubs, reading the latest tech news or developing your own extensions then you might have caught wind of some of these changes yourself.

BigBlueButton is an Open Source virtual classroom started in 2007 by OSI sponsor, Blindside Networks. What differentiates BigBlueButton from other web conferencing platforms is that it’s designed for the education market. It focuses on maximizing time for applied learning and feedback, incorporating tools such as a multi-user white board, breakout rooms, shared notes, polling, and emojis.
Nearly all educational institutions use learning management systems that teachers and students access to manage all the components of classes or programs such as assignments, grades, and lesson plans. Integration with learning management systems is important for the success of an online learning platform, and BigBlueButton is built into the core of some of the most popular options like Moodle, Canvas, Schoology, and D2L.
We are happy to announce that the latest Qt for Android Automotive patch release is available which contains one critical bug fix.
I suppose that I could trace the code, find where the function is failing; however, I took a punt. Sometimes, older versions of a package are better. Developers may start off with something that works, then they add more features and clever things.
There are so many old projects. If you keep looking and looking, using different search keywords, more old treasures are discovered. And links to no-longer-existing projects.
Perl lets you use almost anything as a regular expression delimiter. It is usual to use punctuation of some sort, but characters that match /\w/ can be used provided there is white space between the operator and the delimiter: m X foo Xsmx compiles and matches 'foobar'. In the presence of use utf8; you can go wild.
A query on the Perl 5 Porters Mailing List (a.k.a. 'p5p') a few days ago asked for opinions about appropriating the colon (':') as a delimiter for modifiers to the regular expression operators. This got me wondering about what regular expression delimiters were actually in use.
I scratched that itch by plowing through my local Mini CPAN, running everything that looked like Perl through PPI, and checking anything that parsed to an object of one of the relevant classes. A summary of the results is appended.
OpenVX 1.3 is the modern solution the industry needs for automating computer vision and perception tasks. But first, what is computer vision, and why is it important?
That answer, of course, reveals a certain ignorance of the sector in which I work (completely understandable and moreover symmetrical); but it also shows an idea of the future that is taken for granted by those involved in machine learning and yet it is difficult to conceive - because in many ways literally inconceivable - for everyone else. “People talk about Miami or Bangladesh as if they still have a chance,” said a famous report on climate change whose argument was that they no longer have a chance. Similarly, people talk about translators, communication experts, civil lawyers, authors.
In 2021, the Linux Foundation and the Fintech Open Source Foundation (FINOS) conducted the first annual survey and in-depth study into the State of Open Source in Financial Services. This initial study was important because it was critical to forming a baseline of understanding around what open source activity was taking place within this highly regulated and competitive industry regarding leadership, consumption, contribution, governance, and culture.
In line with our goal of providing velocity updates every six months or so, below are the charts showing open source project velocity over 2022. Thanks to the insights we can glean from these charts, we are able to keep track of the trends and technologies that are resonating with developers and end users.
Linux and PyTorch lead the list of top open source projects from 2022, says Chris Aniszczyk in a recent report from the Cloud Native Computing Foundation (CNCF).
AWS has also heavily supported open standards such as OpenXR and even turned its game engine, Lumberyard, into the Open 3D Engine in partnership with the Linux Foundation to create an open-source game engine that it regularly updates.
A new privilege escalation vulnerability has been identified in the Linux kernel by researcher Davide Ornaghi. This vulnerability might enable a local attacker to execute code on vulnerable computers with elevated rights if the kernel is installed on those systems. Additionally, Davide published the proof-of-concept and the write-up. The vulnerability, which has been assigned the tracking number CVE-2023-0179, is a stack-based buffer overflow that exists in the Netfilter subsystem. An authorized attacker might exploit this issue to get elevated privileges as root if the attacker executed a program that had been carefully written for the purpose.
According to the complaint against him, Al-Azhari allegedly visited a dark web site that hosts “unofficial propaganda and photographs related to ISIS” multiple times on May 14, 2019. In virtue of being a dark web site—€that is, one hosted on the Tor anonymity network—€it should have been difficult for the site owner’s or a third party to determine the real IP address of any of the site’s visitors.
Yet, that’s exactly what the FBI did. It found Al-Azhari allegedly visited the site from an IP address associated with Al-Azhari’s grandmother’s house in Riverside, California. The FBI also found what specific pages Al-Azhari visited, including a section on donating Bitcoin; another focused on military operations conducted by ISIS fighters in Iraq, Syria, and Nigeria; and another page that provided links to material from ISIS’s media arm. Without the FBI deploying some form of surveillance technique, or Al-Azhari using another method to visit the site which exposed their IP address, this should not have been possible.
There are lots of ways to de-anonymize Tor users. Someone at the NSA gave a presentation on this ten years ago. (I wrote about it for the Guardian in 2013, an essay that reads so dated in light of what we’ve learned since then.) It’s unlikely that the FBI uses the same sorts of broad surveillance techniques that the NSA does, but it’s certainly possible that the NSA did the surveillance and passed the information to the FBI.
In real life, the John in the picture above is a guy who never went anywhere close that naked woman which is not his wife. Still, that and other pictures “prove” that John is a really bad guy involved in all sorts of illegal, or otherwise deeply troubling activities that he never took part in in reality.
a table with built-in electronics could sense the temperature of the drink you place down on it and heat or cool just that portion of the surface to maintain the drink’s temperature.
