10 Best Free and Open Source Linux Comic Book Viewers

Filed under
Linux
Software

A comic book is a magazine which consists of narrative artwork in the form of sequential images with text that represent individual scenes. Panels are often accompanied by brief descriptive prose and written narrative, usually dialog contained in word balloons emblematic of the comics art form. Comics are used to tell a story, and are published in a number of different formats including comic strips, comic books, webcomics, Manga, and graphic novels. Some comics have been published in a tabloid form. The largest comic book market is Japan.

Many users associate desktop Linux with their daily repetitive grind. However, we are always on the look out for applications that help make Linux fun to use. It really is a great platform for entertainment.

    Mesa 21.3 feature development is now over with the code having been branched and the first release candidate issued.

    Mesa 21.3 will be the last major feature release to this collection of open-source GPU drivers for 2021. Mesa 21.3 should debut in November if all goes well but until then will be weekly release candidates to help test out the new code that has accumulated over the past three months.

  • More GNOME Software FAIL. Useless software reviews. – BaronHK's Rants

    It’s come to my attention several times now that if you want information about a program for GNU/Linux, don’t bother reading the reviews that people put in GNOME Software.

    Some of it isn’t in English, which is the language that I speak, and GNOME Software doesn’t sort them out based on your preferred language.

    The GNOME Software application doesn’t collect basic information about what distribution of GNU/Linux. (Or if it even is GNU/Linux, as GNOME actually still does run on other *nix systems, but I can’t imagine there’s too many non-GNU/Linux users left).

    It doesn’t consider what package manager you installed the program from.

    It could be from Fedora, it could be from Debian, or Ubuntu, or Arch. It could be a Snap. It could be a Flatpak.

  • New features coming in Julia 1.7

    Julia is an open-source programming language and ecosystem for high-performance scientific computing; its development team has made the first release candidate for version 1.7 available for testing on Linux, BSD, macOS, and Windows. Back in May, we looked at the increased performance that arrived with Julia 1.6, its last major release. In this article we describe some of the changes and new features in the language and its libraries that are coming in 1.7.

    Historically, Julia's release candidates have been close to the finished product, and most users who would like to work with the new features can safely download binaries of version 1.7rc1 from Julia headquarters in the "upcoming release" section. Officially, however, the current version is not "production ready"; the developers welcome bug reports to the GitHub issue tracker.

  • Rust and GCC, two different ways

    Developers working in languages like C or C++ have access to two competing compilers — GCC and LLVM — either of which can usually get the job done. Rust developers, though, are currently limited to the LLVM-based rustc compiler. While rustc works well, there are legitimate reasons for developers to wish for an alternative. As it turns out, there are two different ways to compile Rust using GCC under development, though neither is ready at the moment. Developers of both approaches came to the 2021 Linux Plumbers Conference to present the status of their work.

  • Moving Google toward the mainline [LWN.net]

    Two Google engineers came to Open Source Summit North America 2021 to talk about a project to change the way the company creates and maintains the kernel it runs in its data centers on its production systems. Andrew Delgadillo and Dylan Hatch described the current production kernel (Prodkernel) and the problems that occur because it is so far from the mainline. Project Icebreaker is an effort to change that and to provide a near-mainline kernel for development and testing within Google; the talk looked at the project, its risks, its current status, and its plans.

  • User-space interrupts [LWN.net]

    The term "interrupt" brings to mind a signal that originates in the hardware and which is handled in the kernel; even software interrupts are a kernel concept. But there is, it seems, a use case for enabling user-space processes to send interrupts directly to each other. An upcoming Intel processor generation includes support for this capability; at the 2021 Linux Plumbers Conference, Sohil Mehta ran a Kernel-Summit session on how Linux might support that feature.

  • How Red Hat uses GitLab for kernel development [LWN.net]

    Much of the free-software development world has adopted Git forges (such as GitHub, GitLab, or sourcehut) with enthusiasm. The kernel community has not. Reasons for that reticence vary, but one that is often heard is that these forges simply don't work well at the scale needed for the kernel project. At a Kernel-Summit session during the 2021 Linux Plumbers conference, Donald Zickus and Prarit Bhargava sought to show how Red Hat has put GitLab to good use to support its kernel team. Not only can these forges work for kernel development, they said, but moving to a forge can bring a number of advantages.

  • How Windows NTFS finally made it into Linux • The Register

    Love it or hate it, Linux users in a Windows world must deal with Microsoft's New Technology File System (NTFS). This has always been a pain in the rump. Even after Microsoft finally gave up on its anti-Linux rhetoric and released its patents to the open-source community and expressively opened up its exFAT patents, we still couldn't get into NTFS.

    Things have changed. Starting with the Linux 5.15 kernel, NTFS is finally being fully supported in Linux. This journey hasn't been easy.

    Microsoft introduced NTFS, a proprietary – naturally – journaling file system in Windows NT 3.1 in 1993. From there, it replaced 1977's File Allocation Table (FAT) file system across Windows.

  • Rolling stable kernels [Ed: Microsoft wants Linux to become unstable like Windows]

    [Microsoft's] Sasha Levin, one of the maintainers of the stable kernels, gave a presentation at Open Source Summit North America 2021 on a proposal for a different way to handle the stable tree. He noted that throughout most of the kernel's history, version numbers did not really mean anything, but that the versioning scheme suggests that they do, which leads to a disconnect between how the kernels are seen versus how they are actually maintained. He proposed making a "rolling stable" release that provides users what they need—timely fixes to their kernel—without forcing them to choose to switch to a new version number.

  • How does HTTPS protect you (and how doesn't it?) - The Mozilla Blog

    It’s true that looking for the lock icon and HTTPS will help you prevent attackers from seeing any information you submit to a website. HTTPS also prevents your internet service provider (ISP) from seeing what pages you visit beyond the top level of a website. That means they can see that you regularly visit https://www.reddit.com, for example, but they won’t see that you spend most of your time at https://www.reddit.com/r/CatGifs/. But while HTTPS does guarantee that your communication is private and encrypted, it doesn’t guarantee that the site won’t try to scam you.

    Because here’s the thing: Any website can use HTTPS and encryption. This includes the good, trusted websites as well as the ones that are up to no good — the scammers, the phishers, the malware makers.

    You might be scratching your head right now, wondering how a nefarious website can use HTTPS. You’ll be forgiven if you wonder in all caps HOW CAN THIS BE?

    The answer is that the security of your connection to a website — which HTTPS provides — knows nothing about the information being relayed or the motivations of the entities relaying it. It’s a lot like having a phone. The phone company isn’t responsible for scammers calling you and trying to get your credit card. You have to be savvy about who you’re talking to. The job of HTTPS is to provide a secure line, not guarantee that you won’t be talking to crooks on it.

    That’s your job. Tough love, I know. But think about it. Scammers go to great lengths to trick you, and their motives largely boil down to one: to separate you from your money. This applies everywhere in life, online and offline. Your job is to not get scammed.

  • ModelMesh and KServe bring eXtreme scale standardized model inferencing on Kubernetes

    One of the most fundamental parts of an AI application is model serving, which is responding to a user request with an inference from an AI model. With machine learning approaches becoming more widely adopted in organizations, there is a trend to deploy a large number of models. For internet-scale AI applications like IBM Watson Assistant and IBM Watson Natural Language Understanding, there isn’t just one AI model, there are literally hundreds or thousands that are running concurrently. Because AI models are computationally expensive, it’s cost prohibitive to load them all at once or to create a dedicated container to serve every trained model. Also, many are rarely used or are effectively abandoned.

    When dealing with a large number of models, the ‘one model, one server’ paradigm presents challenges on a Kubernetes cluster to deploy hundreds of thousands of models.

  • The Application Hierarchy of Needs for SREs and IT Operators – IBM Developer

    The Hierarchy of Needs was defined by the psychologist Abraham Maslow in his paper “A Theory of Human Motivation.” The base of the pyramid contains the most fundamental and most critical needs, with each subsequent layer representing needs that become important once those of the preceding layer have been satisfied.
    Maslow’s “Hierarchy of Needs” was used to represent the needs and behavioral motivation drivers for humans. This pyramid represented a series of basic psychological and self-fulfillment needs.

    Maslow’s hierarchy of needs has been adapted and adopted to represent the needs and motivations in other domains, including the needs of applications and services being managed by SREs and IT Operations teams.

  • Going to market with an open source product

    Many people with a long career in engineering, including me, have had misconceptions about sales and marketing. As an engineering community, we've viewed it as things like ordering swag, naming things, running ad campaigns, and creating white papers. There's a joke in the marketing community about how engineers are always willing to provide their "opinions" on marketing decisions without fully comprehending the discipline, but marketers rarely—like never—make suggestions on code improvements. To work together, engineers and marketers must share a common definition.

    While product marketers do help drive those commonly recognized tasks, the role is so much richer. Product marketers, technical marketers, and evangelists have outbound responsibilities like creating content (e.g., blogs, press releases, white papers, demos), delivering roadmap sessions to customers (as well as analysts and journalists), building content for sales teams, and much more. Combined, these outbound functions are often referred to as getting a product to market, but just as importantly, product marketing also has inbound functions. They serve as another set of eyes and ears to listen for customer needs and provide input to the product strategy. There's a saying in product management: nothing interesting happens within these four walls. Businesses must go out into the world, talk to customers, and more importantly, listen to them.

  • After Spike in Ransomware Attacks, U.S. Looks to Go on the Offensive [iophk: Windows TCO]

    The Biden administration has sought to rally its allies to help fight cyberthreats and ransomware attacks, pushing NATO to adopt a new cyber defense policy and launching talks on cyberthreats among G-7 nations. It also launched a series of initiatives in recent months to target cybercriminals and boost protection against ransomware attacks following several high-profile ransomware attacks against a major oil pipeline company and a meat-processing company earlier this year. The attacks laid bare how vulnerable elements of U.S. critical infrastructure, including its food and energy sectors, were to cyber incursions.

    Vicente Diaz of VirusTotal said in a short blog post accompanying the 14-page study that of the 140 countries which submitted ransomware samples, Israel was far and away an outlier with the highest number of submissions and nearly 600% rise in submissions compared to its baseline.

  • End of Life Google Chrome devices should be repurposed with GNU/Linux. – BaronHK's Rants

    Of all companies, Lenovo gave me an idea.

    They mentioned GalliumOS as a potential Chrome OS replacement on some of their own Chrome devices.

    These are considered low end by PC standards, but they run Chrome OS fine because it’s a stripped down GNU/Linux system. Not some bloated 100 GB+ Windows horror that has to trap every file system call in case it’s a virus.

    The Intel-based ones, mostly, should run a normal GNU/Linux distro, but they occasionally have odd hardware in them that’s not well supported by the vanilla Linux kernel, and GalliumOS steps in to add those.

    Many years ago, there was a guy running a charity in Texas that took old computers that were not able to run Windows anymore, and re-imaged them with a minimum GNU/Linux distribution, which they were able to run okay.

    Somewhere, out of the blue, Texas sent the police in to enforce “environmental standards”.

  • macOS 11.6 makes the theme worse then ever. Free Software GUIs are whatever you want them to be. – BaronHK's Rants

    Jamie Zawinski commented that his perfect Mac experience continues with light grey text on light grey backgrounds.

    These have been a problem for years, and it’s only getting worse.

    It’s why I use the Adwaita-Dark theme and Solarized Dark for Gedit and GNOME Terminal.

    I think they’re all making the default theme so unusable unless you jack up the display backlight to “IT BURNS US! IT BURNS US PRECIOUS!” so they can market “Dark Mode” as if it was a special feature, when I’ve always used them in one form or another.

    When I started using Solaris, I got hooked on one that Sun wrote for GTK2 called Nimbus. The icon pack was pretty sharp too. And even the light version was quite lovely.

  • Reasons to limit your stack size even in non-threaded environments

    One reaction to learning that 4BSD is where Unix started to have a stack size limit is to ask why you would bother with a stack size limit at all in an environment without threads (where a process will thus only ever have one stack). There are a number of reasons that operating systems have generally done this, and probably why it starts in Unix in the 4BSD line, which ran on 32-bit VAX systems instead of the 16-bit PDP-11s that V7 did.

  • Toggle Light & Dark Mode for Flatpak Apps in Ubuntu 20.04+ / Linux Mint | UbuntuHandbook

    Using Flatpak apps in Linux? You may found that Flatpak app appearance does not change when toggling light & dark mode or switching to another app theme.

    As more and more apps publish Linux packages via Flatpak, I have a few of them installed in my Ubuntu laptop. However, the apps stick to the light theme whenever I switches to dark mode in Appearance settings.

    Since Flatpak runs in sandbox and does not have permission to access the “/usr” directory, it does not use system theme according to the document. So, some popular GTK themes are packaged as Flatpaks. And, it detects the current system app theme and tries to install the Flatpak version of the theme if available during app installation or update.

    I’m working with default Yaru theme in the most time, so it automatically installs Yaru theme flatpak package but leaves Yaru Dark not installed. When I switching to Yaru Dark, it can’t find the match theme so falls back to the default Adwaita.

  • Sending logs to Panther using syslog-ng - Blog - syslog-ng Community - syslog-ng Community

    Panther is an open-source log management system, which is also available as a service for a time-limited trial. It is still in beta phase, but it looks promising. You can see the “beta” sign on its opening page: https://app.panther.support/ I tested the time-limited cloud service version, but you can also install it locally, either from Dockerhub, or you can build the containers locally from the source.

    Even if it is still in beta phase, Panther comes with detailed documentation. There is a notable exception: while syslog-ng is shown on some of the figures, documenting it is still to be done. This blog helps you to get started with sending logs to Panther, using syslog-ng. You can use either legacy syslog with TLS encryption (still a bit problematic) or the http() destination to send logs to the Panther HTTP API.

    Docker is an open-source application that provides lightweight operating-system-level virtualization through the use of containers. It is a kind of virtualization technology that is specially designed to easily develop and deploy applications inside of neatly packaged virtual containerized environments. Docker containers are in essence a set of software packages that run as one application that’s isolated from others. We can deploy it to any machine without any compatibility issues. By using this, the software stays system agnostic, simpler to use, less work to develop, and easy to maintain.

  • How to connect Rocky Linux 8 via Windows RDP protocol - Linux Shout

    If you have Rocky Linux 8 desktop and Windows 7/10/11 in a local environment and want to access using the RDP- Remote desktop protocol, then here is the way.

    To connect Linux operating systems such as Rocky Linux, AlmaLinux 8, or CentOS, we can use the open-source implementation of Remote desktop protocol called XRDP. RDP is developed by Microsoft and has been an integral part of Windows operating systems. It allows the users to remotely control and use the GUI desktop systems just like a local one. Although, Windows can be operated over this protocol out of the box, for Linux we need to install some additional packages. Here we learn how to set up a remote desktop connect to Rocky Linux 8.

7 Important Linux Commands for Every Linux User

Filed under
GNU
Linux

Linux might sound scary for first-time Linux users, but actually, it isn’t. Linux is a bunch of open-source Unix operating systems based on Linux Kernel. These operating systems are called Linux distributions, such as Fedora, Debian, Ubuntu, and Mint.

Since its inception in 1991, Linux has garnered popularity for being open-source. People can modify and redistribute Linux under their own brand. When using a Linux OS, you need a shell to access the services provided. Also, it’s recommended to run your Linux OS through a CLI or command-line interface. CLI makes time-consuming processes quicker.

This article presents a guide to 7 important Linux commands for every Linux user to know. So, let’s begin.

What is the Linux Operating System?

Filed under
GNU
Linux

The Linux kernel is the main component of the Linux operating system. In general terms, the kernel is a software code that serves as a layer between the hardware and main programs that run on a computer. It was created by Linus Torvalds back in the early 1990s in Finland and licensed under the GNU General Public License (GPL). In other words, Torvalds was made the Linux kernel available to the world for free. There is an official website for the Linux kernel.

The rest of the system consists of other programs, many of which were written by or for the GNU Project. These utilities were then added to the Linux kernel to create a complete system. The kernel is an essential part of an operating system, but useless by itself, because the Linux kernel alone does not form a working operating system. It can only function in the context of a complete operating system.

The Linux kernel is used by Linux distributions alongside GNU tools and libraries that interact with it. This combination is sometimes referred to as GNU/Linux.

So Linux is just a kernel, but the term Linux is far more commonly used by the public and media and that it serves as a generic term for systems that combine that kernel with software from multiple other sources. Therefore when most people say Linux, they’re really talking about a combination of the Linux kernel plus a lot of tools and libraries from the GNU Project.

To put it more clearly, Linux and GNU/Linux refer to the same operating system and software. There is still a controversy over which term is more appropriate.

  • How To Install NVIDIA Drivers on Fedora – TecAdmin

    Fedora, the operating system of RHEL(Red Hat Enterprise Linux) does not have pre-installed exclusive Nvidia drivers in it for the users. Although it does have default Nouveau drivers which work in most conditions, you may face some problems while using them. If you encounter issues while using the Nouveau drivers you will have to install the official proprietary Nvidia drivers.

    The official Nvidia drivers can help you get the most out of your GPU by enhancing its performance. In this article, we will learn to install the official Nvidia drivers on Fedora

    However, before we start with the installation process, we need to do system configuration. The first configuration we need to do is stop the GUI from running and the second step is to disable the default nouveau drivers. From the GRUB boot menu, it is really easy and doable.

  • Security Risks of Client-Side Scanning

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

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

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

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

  • Cluster Scheduler Support Queued Ahead Of Linux 5.16 - Phoronix

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