      In Why I Wrote the Linux Cookbook, 2nd Edition, I discussed how much Linux has changed in a short time, and how I updated the Linux Cookbook to include some of these changes. Now I will share some snippets from the new book, so you can get a taste of how fabulous it is, and inspire you to dash out and buy many copies.

    • Sick of Windows? Here's how easy it is to install Linux

      Linux isn't nearly as challenging as you've been led to believe. In fact, it's just as easy to use as any other operating system. But what about the installation? Wouldn't installing an operating system be a challenge that's way above the paygrade of the average user? Not necessarily. And now that you know how to test-drive Linux, it's time you learned how to install the open-source operating system.

      Like the previous entry in this series, I'm going to focus on elementary OS because it's one of the more user friendly distributions, and the installation is fairly indicative of the average Linux installation.

      • The 5 best Linux desktops for beginners in 2021

        Some people still insist that using Linux is hard. Sure, it was difficult -- when I started with the Linux desktop back in the 1990s. But that was a long time ago. Today, the easiest desktop of all, Chrome OS, is simply Linux with the Chrome web browser on top of it. The more full-featured Linux desktop distributions are as easy to use in 2021 as Windows or macOS.

        Yes, you can get a lot more from Linux if you know how to do shell programming and the like. But that's also true of Windows and PowerShell. With both operating systems, you don't need to know the deep ins and outs of either one to get your work done.

      • AWS adds Linux app streaming alongside Windows to 'greatly lower' cost

        Amazon Web Services has added support for streaming Linux applications and desktops to its AppStream service, which was previously Windows-only, claiming that it will "greatly lower the total streaming cost."

        AppStream 2.0 has been running since late 2016 and enables users to stream GUI applications or entire desktops to a local PC either via a web browser or using a Windows client. Although running applications remotely has some drawbacks – such as latency, dependency on a strong internet connection, and potential snags accessing local resources like printers and storage – it also has advantages.

      • Unsplash Wallpapers Is An Unsplash Desktop Open Source App

        You may have heard about Unspalsh; a very famous online service that provides high-quality images and wallpapers under a semi-open license.

        Unsplash is important for website creators, app designers and basically anyone who wants to get free wallpapers without having to deal with licensing issues (No attribution required, and even commercial usage of Unsplash images is allowed). It was a revolution in stock images when it first started.

        For the average user, though, nothing more is needed than setting these beautiful wallpapers as a background image for his/her operating system’s desktop. And for that, a desktop application is going to be needed.

      • Sound Open Firmware For AMD Audio Hardware Arrives, Initially For Renoir ACP - Phoronix

        Back in 2018 Intel founded Sound Open Firmware as their effort to provide an open-source audio DSP firmware and software development kit. AMD has begun supporting Sound Open Firmware too now, initially for the Renoir audio co-processor (ACP).

        Sound Open Firmware as a Linux Foundation project has been maturing over the past three years and now supports a wide-range of Intel hardware with other audio hardware also becoming supported. Ultimately it's about having open-source audio DSP firmware and a SDK to better support modern audio processing. In the SOF documentation it's summed up rather broadly, "The Sound Open Firmware SDK is comprised of many ingredients that can be customized for use in the firmware/software development lifecycle. Customization allows for a “best fit” development approach where the SDK can be optimized for a particular process or environment. Some SDK ingredients are optional while there can be more than once choice for other ingredients."

      • Linux 5.17 To Support Temperature Monitoring For New AMD Zen Generation - Phoronix

        The Linux 5.17 kernel next year will support temperature monitoring for a "new generation" of AMD Zen processors.

        While AMD has often been late to the game in supporting CPU temperature reporting under Linux for Zen processors, it's nice to see them out in front ahead of their next launch. Even in cases where new IDs simply need to be added to the k10temp driver, unfortunately they have often not added them until post-launch or in some cases where those in the community (including cases like I when getting hands on review samples) have the hardware and find the support not working until making some trivial driver alterations.

        One of the most popular applications to feed Splunk with syslog messages is syslog-ng. However not everyone is happy to work on the command line anymore. This is where syslog-ng store box (SSB), an appliance built around syslog-ng, can help. The SSB GUI provides you not only with an easyto-use interface to configure most syslog-ng features, but also a search interface and complete log life cycle management. It can forward log messages to several destinations, recently also to Splunk’s HTTP Event Collector (HEC).

        From this blog you can learn about how SSB fits into your logging infrastructure and how to configure SSB for Splunk.

        MariaDB is one of the most popular open-source databases next to its originator MySQL. The original creators of MySQL developed MariaDB in response to fears that MySQL would suddenly become a paid service due to Oracle acquiring it in 2010. With its history of doing similar tactics, the developers behind MariaDB have promised to keep it open source and free from such fears as what has happened to MySQL.

        MariaDB has become just as popular as MySQL with developers, with features such as advanced clustering with Galera Cluster 4, faster cache/indexes, storage engines, and features/extensions that you won’t find in MySQL.

        The grep command, which stands for global regular expression print, is one of the most versatile commands in a Linux terminal environment. It is an immensely powerful program that allows the user to sort input according to complex rules, which makes it a rather popular link in numerous command chains. The grep command is primarily used to search text or any file for lines that contain a match to the specified words/strings. By default, grep displays the matched lines, and it can be used to search for lines of text that match a regular expression(s), and it outputs only the matched lines.

      • How to create an SQS Queue on AWS

        Amazon Simple Queue Service (SQS) is a managed message queuing service of AWS which enables us to decouple and scale microservices, distributed systems, and serverless applications. Using SQS, we can send, store, and receive messages between software components at any volume, without losing messages. Standard queues offer maximum throughput, best-effort ordering, and at least-once delivery. FIFO queues are designed to guarantee that messages are processed exactly once, in the exact order that they are sent.

        • Evolving 3D desktop effects in Plasma

          The latest Plasma release dropped a few desktop effects: the cube family, CoverSwitch and FlipSwitch. All of those effects were written back in 2008, the early days of KDE 4.x and the early days of desktop effects in KWin. The effects were implemented by me and when Vlad asked about removing them I saw the need for this and supported this step for technical reasons. With this blog post I want to share a little bit of why it was needed to remove them and why this means that they can come back in better ways than ever before.

          To really understand this we need to time travel back to 2008 and the years before when desktop effects were introduced. This can help to understand how the hardware architecture changed and how that influenced design decisions in the effects API which are nowadays problematic. First of all CPUs. The Intel Core 2 Duo architecture was launched in 2006 as the brand new thing which had multiple (namely 2) cores which slowly replaced the NetBurst architecture which dominated Desktop computing for the beginning of that decade.

        • China has now used a major Safari/Webkit zero day vulnerability against Hong Kong activists for at least the second time.

          On GNOME Web (especially in Flatpak), it’s actually quite a bit safer because of advanced Linux sandboxing techniques, and additional hardening options available to the GNU Compiler, which simply either don’t exist or are broken, or fake (report success, do nothing) in Apple’s Clang/LLVM. In many cases, the browser would simply crash rather than arbitrary code execution.

          I really can’t tell you how much I dislike Clang/LLVM. Apple switched over to it from GCC not due to maturity or technical excellence, but to get away from the GNU GPLv3, and now it’s democracy protesters in China who get to pay for that.

          When Fedora’s engineering steering committee was debating switching to LLVM based on anti-GNU FUD coming from Mozilla, I was preparing to apply two patches to Firefox (someone else quickly wrote them to make Firefox build on GCC with the features Mozilla said weren’t possible in GCC 8, to justify their switch to an inferior compiler) and build it under some other name and put it in my COPR repo instead. Now I don’t use Fedora or Firefox.

          If that had been the only thing going wrong with it, I might have groused a little and stayed in the end, but IBM has moved Fedora in a direction where it’s even less stable than Debian Sid!

          And Mozilla has turned into a political party of extremism (wokeness/corporate leftism) and Cancel Culture, and a thrall of Big Tech.

        Luck is a combination of two factors: probability and time. Case in point, my foray with MX Linux MX-21 KDE. As you well know, I'm a great fan of this small yet feisty distro. So far, I've mostly tested (and liked) the Xfce flavors. My one quick brush with its KDE build was largely unsuccessful. In fact, with the release of MX-21 Wildflower, I wasn't even thinking of testing the KDE version.

        But then, as luck would have it, the official download page didn't have the Xfce release available for my Lenovo IdeaPad box. To be able to run on modern systems with UEFI, AMD Ryzen processors and NVMe, you need the AHS release - I discovered this with MX-19.3. However, at the time of writing, or rather testing, there was only the regular Xfce edition sans modern stuff, the Xfce AHS in almost-but-not-quite Release Candidate (4), and the KDE version, with all the right bits in place! So I thought, let's go for it.

        • Customize Python dependency resolution with machine learning | Red Hat Developer

          It has not been that long since pip, the Python package installer, introduced a new resolver. A resolver is a critical piece of programming infrastructure, responsible for locating and selecting versions of packages to use when building an application. The new pip resolver uses a backtracking algorithm that works considerably better than the old one, according to community feedback.

          This article introduces a new cloud-based Python dependency resolver created by Project Thoth. Running in the cloud, Thoth uses reinforcement learning techniques and your desired criteria to resolve Python library dependencies. Moreover, a pluggable interface lets you fix underpinning and overpinning issues (that is, where specified versions of packages are too strict or too lax) and make additional adjustments to the resolution process. The process takes into consideration the runtime environment, hardware, and other inputs to the cloud-based resolver.

        • From Godot to RPM - Fedora Magazine

          With more games being developed with the Godot engine, we need to learn how to package these games for Fedora.

          Developing a game is complex. The requirements for each game differ. In the past developers created new game engines for each game. Over time game engines become more generic. They adapt to cover a style of game. Some engines can create a wide variety of games.

          Godot is a well known open source game engine. Both open source and closed source games use the system. The Godot packages for Fedora run these games but no RPM package examples exist.

          Much of the packaging is the same regardless of the application. RPM spec files need summary, version, license, description, etc. For build requirements, you need the godot-headless package. Godot publishes a pck file but requires a graphical user interface to run. Godot headless builds a project without needing a graphical user interface.

        • Managing persistent volume access in Kubernetes | Red Hat Developer

          Data storage gets complex in the world of containers and microservices, as we discussed in Part 1 of this series. That article explained the Kubernetes concept of a persistent volume (PV) and introduced Red Hat OpenShift Data Foundation as a simple way to get persistent storage for your applications running in Red Hat OpenShift.

          Beyond the question of provisioning storage, one must think about types of storage and access. How will you read and write data? Who needs the data? Where will it be used? Because these questions sound a bit vague, let's jump into some specific examples.

          I ran the examples in this article on Developer Sandbox for Red Hat OpenShift, a free instance of OpenShift that you can use to begin your OpenShift and Kubernetes journey.

        • The office's next chapter: How CIOs can shape a positive workplace experience | The Enterprisers Project

          When the pandemic hit, the first wave of transformation was about moving employees home and supporting remote workers. The result of that transformation has forever changed our workforce – today, people are able to get work done from anywhere.

          It’s also forever changed the role of the physical workplace. The office will always have an important role in work. And as employees continue to return to the office, it’s time to think about how we can make it a place where people want to be – not just need to be – and a place where they can work effectively.

          Creating an enticing workplace experience is nothing new; years ago, tech companies in Silicon Valley began offering perks such as chef-prepared meals in the cafeteria and massages to attract and retain top talent. Today, the pandemic has employees reflecting on what benefits are important to them and which jobs align with their values, wants, and needs in a career. The perks that get them excited to come into the workplace might change. After working from home, for example, they likely crave time for collaboration and socializing in the workplace. And it’s up to us to help rethink that workplace experience with sustainability and employee needs in mind.

          After the warp-speed transformation CIOs have experienced over the last two years, now is not the time to slow down. As you look toward the near future, focus on improving the workplace experience, including by leveraging data from sensors and forming stronger cross-functional partnerships that can drive your organization forward.

        • 3 things CIOs should know about developers in the cloud era

          What do today’s developers wish CIOs and IT leaders knew about the realities of the cloud era? What do developers want in order to advance their careers? For my first episode hosting Red Hat’s livestreaming show, In The Clouds, I was excited to dig into these and related questions around the role of developers in the enterprise. I was joined by the leaders of the Red Hat Developer Business Unit: Vice President and General Manager Mithun T. Dhar and Senior Director of Developer Marketing and Strategy Ignacio Riesgo Pablo. We had an excellent discussion about how Red Hat works with developers and the unique culture and opportunities that brought all three of us to join the company.

        • The future of documentation at Canonical

          We’ve understood the importance of this for some time, but actually finding a way to express those values in our practice is less easy.

          One thing that has made it difficult at Canonical is the complexity of our engineering, product and services portfolio. Our software spans a range from single-purpose command-line tools to vertical ecosystems composed of dozens of discrete component products, created by dozens of independent engineering and product teams.

          We’ve been able to create unified and coherent software product lines, but we’ve been less successful doing the same for documentation. We want to do better for our documentation users – this is how we’re going to do it.

        • Nasah Kuma: open source is flexible

          I had as main objective when I started my Coding Experience(CE) to get to grips with C or C++ since I am convinced that understanding one or both languages will help me become a better developer. Cog is developed in C which explained my excitement when I was introduced to the project. The first couple of tasks assigned to me were challenging but quite beginner-friendly.

          Like it usually happens to many developers, I got stuck on an issue. After weeks of working on it, I couldn’t complete it. My mentor and I had a couple of meetings/coding sessions which helped me move ahead though not to the point of finishing the work. I could feel that there was a knowledge gap I had to bridge in C which studies and practice hadn’t given me that ability yet. Cutting the long story short I got really exhausted and anxious and suggested to my mentor that we move to something else and revisit this issue later.

          After a couple of days, I was presented with a new program that can help me make the most of the CE. It turns out I will be moving back to contributing actively on GJS since there was good progress when I previously contributed to it. The only difference is most of my contributions will be in C++ and will probably include more core stuff.

        • Hacking Multiplication with Karatsuba’s Algorithm

          People tend to obsess over making computer software faster. You can, of course, just crank up the clock speed and add more processors, but often the most powerful way to make something faster is to find a better way to do it. Sometimes those methods are very different from how a human being would do the same task, but it suits the computer’s capabilities. [Nemean] has a video explaining a better multiplication algorithm known as Karatsuba’s algorithm and it is actually quite clever. You can see the video below.

          To help you understand the algorithm, the video shows a simple two-digit by two-digit multiplication. You can see that the first and last digits are essentially the result of one multiplication. It is all the intermediate digits that add together. The only thing that might change the first digit is a carry.

        We’ve lost a lot of things in recent years, but one that we haven’t talked about too much is the demise of the children’s radio station. Yes, this is not exactly a surprise—how is radio going to compete with YouTube and Roblox? But back in April, the only real player in the kid-centric terrestrial radio space, Radio Disney, which started life on the airwaves 25 years ago this week, quietly wound down as Disney made the decision to focus on, well, every other part of being Disney. But it’s worth noting that Radio Disney was not the only one to embrace this phenomenon. Kids’ music makes a lot of money even to this day—it’s part of the reason why traditionally adult-centric bands like They Might Be Giants have embraced it. Today’s Tedium looks back at the many attempts to sell kids on radio—a market that has basically faded away by this point.

          • Is Microsoft Stealing People’s Bookmarks?

            I received email from two people who told me that Microsoft Edge enabled synching without warning or consent, which means that Microsoft sucked up all of their bookmarks. Of course they can turn synching off, but it’s too late.

            Has this happened to anyone else, or was this user error of some sort? If this is real, can some reporter write about it?


            It’s actually worse than I thought. Edge urges users to store passwords, ID numbers, and even passport numbers, all of which get uploaded to Microsoft by default when synch is enabled.

          • Linux has a serious security problem that once again enables DNS cache poisoning

            The sleight of hand worked because DNS at the time relied on a transaction ID to prove the IP number returned came from an authoritative server rather than an imposter server attempting to send people to a malicious site. The transaction number had only 16 bits, which meant that there were only 65,536 possible transaction IDs.

            Kaminsky realized that hackers could exploit the lack of entropy by bombarding a DNS resolver with off-path responses that included each possible ID. Once the resolver received a response with the correct ID, the server would accept the malicious IP and store the result in cache so that everyone else using the same resolver—which typically belongs to a corporation, organization, or ISP—would also be sent to the same malicious server.

        There were no verifiable, centralised records of Internet shutdowns in the country. Neither the Ministry of Home Affairs nor the Department of Telecom maintain such a record, the parliamentary standing committee on information and technology pointed out in its report adopted on Tuesday.

        The committee, headed by senior Congress leader Shashi Tharoor, pressed for a detailed study on the economic impact owing to frequent and prolonged Internet shutdowns.

        Advocacy group Access Now, in a study published in March last, reported that India topped the list of countries that resorted to government imposed Internet clampdown.

        The report, as per sources, said that in absence of the database there was no mechanism to review whether the Internet clampdowns followed the laid down rules or the Supreme Court guidelines.

Instead of all things being composed of one elementary substance, as in philosophical accounts of the monad, in this cosmic vision, we all live in a sea that we cannot see, which Baraduc names Somod.
