        Learn to shade a comic in Krita the way I shaded Episode 34 of my webcomic Pepper&Carrot ( https://www.peppercarrot.com/en/article467/episode-34-the-knighting-of-shichimi ). The video is detailed and goes step-by-step to explain in details what I’m selecting; and more importantly maybe, why. It might sounds like this setup is long to do, but if I’m not explaining it; adding the hardlight, the mid-grey and the selection by color label can be done within a minute. It then allows to shade quickly the panels. This video follows a series of two videos: a timelapse about inking a page of this episode, and a detailed video about the flatting of the page with the colorize-mask feature of Krita.

      • Ubuntu 21.04 – X.Org vs. Wayland Linux Gaming Performance

        One of the most significant underlying changes with the recent release of Ubuntu 21.04 is the default GNOME Shell desktop environment is running the Wayland-based session by default rather than the traditional X.Org Server session. But what does this mean for the Linux gaming performance on Ubuntu 21.04? Here are some (X)Wayland vs. X.Org benchmarks.

        Ubuntu 21.04 is using the Wayland-based GNOME session by default on supported (namely non-NVIDIA) setups. However, via the log-in manager one can easily switch back to GNOME on X.Org if desired for testing/comparison purposes or if finding issue with the Wayland support.

      • Stop logging as root in 5 simple steps

        Do you still manage your virtual servers with the root superuser? Here are five easy steps to stop using root right now.

        This post is for people with an SSH-based authentication on Fedora, CentOS, or RHEL servers. If you spin up a virtual server online, you can usually choose to use an SSH-based authentication instead of providing a password. That’s great! But the initial connection would be set up for the root superuser, and that’s not a good idea.

        The first step to using root less is to stop using it to log in. You can do that by choosing a new admin account with sudo privileges and reuse the root SSH server configuration. Here’s how.

      • Gaming on Linux: Guide to Graphics

        GPUs are in short supply across the board due to delays brought by COVID-19, but don’t fret! Now is the perfect time to plan out your dream machine. If questions surrounding your graphics preferences render you confused, we’ve compiled some useful info below on NVIDIA GPUs and AMD GPUs, as well as suggestions for how much power you may desire.

        Don’t I just need a GPU?

        For games that require less rendering, any GPU will run just fine, like the NVIDIA GeForce GTX 1060 that’s served you well over the years. However, if you want newer games to run like smooth butter at their maximum settings, your old GPU puts a technical limitation on which ones you can add to your library.

        While the 3D space is more intensive, the use of simpler models and less detailed textures reduces the computing power necessary to make any derpy shapeman game run beautifully.

      • Total War: ROME REMASTERED from Feral Interactive is out now

        Total War: ROME REMASTERED from game developer / porter Feral Interactive and Creative Assembly with SEGA as publisher is now officially out with Linux support. [...]

        Bringing us another quality natively supported game originally known as Rome: Total War, Feral really pulled out all the stops on this one. Some remasters simply give a refreshed look but this is a truly huge revamp of all parts of the game allowing people to relive a favourite and for Linux users – to play through it perhaps for the first time.

        The file size got a bit big for their liking though, so you will notice that a free DLC is available right away with the Enhanced Graphics Pack. Not surprising though, because together the installed size comes right up close to 70GB – so if you want the true full experience be sure to have some space ready.

        [...]

        If you did play the original, you’re in for an upgraded nostalgic treat. For everyone else, it makes it super easy to get into. Overall, it’s absolute fantastic. To see Feral Interactive continue to support Linux with some great ports is wonderful. They’ve done another brilliant job, not that we expected any less from them. It’s an easy recommendation to pick up if you love strategy games and previously missed out it due to the original lacking Linux support. It just became one of the best strategy games available on Linux.

      • K Desktop Environment/KDE SC/Qt

        • Health of the KDE community

          Today, I decided to look at KDE git history and look at the project’s health as a whole. It’s inspired by the work of Hans Petter Jansson for GNOME and use the tool he made (fornalder).

          fornalder is easy to use and the documentation in the readme was beneficial. I don’t know if this is because it was programmed in Rust but fornalder was blazingly fast and most of the time spent during this analysis was spent on cloning the repos.

          These stats include all the extragear, plasma, frameworks and release service repository as well as most of the KDE websites and a few KDE playground projects I had on my hard drive. For example, it doesn’t includes most of the unmaintained projects (e.g. kdepimlibs, kdelibs, koffice, plasma-mediacenter, …). Also important to note, is that this doesn’t include translations at all, since they are stored in SVN and added in the tarballs during the releasing process.

      • Modern Lightweight Linux Distro Showdown: Who is the Champion?

        As a Linux user, I was recently in search of a Linux distribution (distro) that is lightweight and runs efficiently on a virtual machine or a physical machine using minimal resources. In the end, only 1 would be chosen as the lightweight Linux distribution of choice. It would have to be good enough to deploy as a daily-driver on my main machine. So, I began the online search and found many articles recommending copious distros which claim to check the boxes for the aforementioned requirements. Needless to say, the number of returned results was staggering.

        The Long List of Contenders

        The distros which were recommended most commonly have been compiled into a list of contenders as shown below. Whenever possible, the most recent stable release of each distro was chosen. The values provided for the “RAM” and “Disk Space” columns are the preferred/recommended system requirement values (not the minimum system requirement values).

        [...]

        After installing each of these distros on a virtual machine and getting to know more about them (especially at an idle state), the following comparison is being made. The difference of CPU usage at an idle state amongst the distros is negligible. When we start to look at RAM utilization and hard disk space, the clear stand-out is Lubuntu. The LXQt desktop really puts the Qt framework in a whole new light (pun alert) of being lean and efficient, especially in terms of memory usage at idle.

      • IBM/Red Hat/Fedora

        • My immutable Fedora

          For many years now, I’ve been using immutable versions of Fedora. I remember that I started to play with immutable Fedora back in 2015 when Fedora Atomic was new. I liked the idea since the first time I’ve read about it, but in the beginning, I did not spend too much time making it work on my setup because it seemed a little bit too complex. At DevConf.cz 2016, I met Patrick Uiterwijk, who was running his spin of Fedora Atomic. We had a long chat on it, and he explained to me his workflow. Soon after, I started to use an immutable version of Fedora on my personal laptop, but I was not daring to use it on my work laptop. When I left Red Hat at the end of 2017, my personal laptop became my only laptop for a little while, and the immutable Fedora became my only OS. Since then, I’ve been using only immutable Fedora on my computers. In June 2020, I took the time to clean up my build process and files, and I moved all the needed bits to a new git repo that is now openly available and can be found here .

          If you are wondering what’s an immutable OS and why it’s different from a “mutable” (or “standard”) OS, the short version of it is that with an immutable OS, when the OS is running, the OS filesystem is in read-only mode. Therefore no application can change the OS or the installed applications. This aspect has many implications, one of which is that you can not upgrade or alter the installed software, but you need to “re-install” the whole OS while the OS is not running. This feature can seem more a problem than a feature, but as we will see, it’s not, and actually, it does bring a lot of advantages.

        • Fedora Linux 34 has landed, and it’s an exquisite take on the desktop

          When last I wrote about Fedora 34, the desktop operating system was still in beta. I tested that beta and found it to be a remarkable step forward for Fedora Linux. I called it a game-changer. Why? Let me count the ways.

          First, there’s GNOME 40, which turns this particular open-source desktop workflow into a thing of beauty. Although I already felt GNOME had a pretty decent workflow, everything changes with this latest iteration. Switching from the vertical to horizontal layout might seem like a small change, but it’s quite profound in how well it ups the efficiency of the desktop. Everything just makes sense now; so much so that I keep asking myself, “Why didn’t the GNOME developers do this all along?”

        • Tomasz Torcz: At some point UI loses usefulness

          When it comes to configurability, modern software often hits a sweet spot. We are given nice, usable User Interface (UI) helping with configuration – by hinting, auto-filling and validating fields. Additionaly, the configuration itself is stored in text format, making it easy to backup and track changes. For example in git version control system.

          [...]

          Argo CD is a wonderful tool to implement GitOps with you Kubernetes cluster.

          Kubernetes is configured by plain text files in YAML format. That’s a perfect form to track in git. Argo CD provides synchronization service: what you have in git repository is applied to kubernetes. Synchronization could be automatic or you can opt to sync manually. In later case, Argo CD provides a nice diff view, showing what’s currently configured and how should it be.

          Argo CD also has a nice concept of responsibility boundaries: it cares only about YAML sections and fields present in the git repo. If you add new section on the running cluster, it won’t be touched. It may be a single field, for example – replicas:

          Above can be utilized when you manage Argo CD by Argo CD. install.yaml file defines configuration resources likes ConfigMaps and Secrets, yet it doesn’t provide actual data: sections. When you configure Argo CD installation – using nice web UI, no less – data: sections are created and configuration is stored into k8s cluster.

          Those sections are not part of what is stored in git repository, so they will neither be touched nor rewritten.

          But what happens when we want to store the Argo CD configuration in the repository, and gitops it to the Moon and back?

          If we add data: sections, they will be synced. But we will lose ability to use nice UI directly! As UI makes changes on the running cluster, Argo CD will notice live configuration differs from git repository one. It will overwrite our new configuration, undoing changes.

          If we want to gitops configuration, we basically must stop using UI and manually add all changes to the text files in the repository!

          We are excited to announce the availability of CuPy v9.0.0. This release contains the effort of development in the past 7 months, including CUDA JIT to transpile Python code to CUDA, support for NVIDIA cuSPARSELt, AMD ROCm support through binary packages, and so on.

        • CuPy 9.0 Brings AMD GPU Support To This Numpy-Compatible Library – Phoronix

          In recent months there has finally been more open-source projects traditionally focused on NVIDIA GPU compute beginning to offer mainline Radeon support using the open-source ROCm stack. Following the recent PyTorch 1.8 with ROCm support, CuPy 9.0 was released last week with that traditionally CUDA focused library now supporting AMD’s ROCm stack.

          [...]

          CuPy 9.0 also features some performance improvements and improved documentation. The new AMD GPU support has been tested against ROCm 4.0.

            WordPress is probably the most used CMS in the world (it is estimated that almost 40% of all websites are built using the platform): it is very easy to install and use, and allows even non-developers to create website in few minutes. WordPress has a very large plugin ecosystem; one of the most famous is Woocommerce, which allows us to turn a website into an online store in few steps. The plugin makes use of the WordPress REST API infrastructure; in this tutorial we will see how to interact with the Woocommerce API using the Python programming language, showing how to list, create, update and delete products and categories.

          • Wireless MicroPython Programming With Thonny | Hackaday

            I had all but given up when by chance I saw this video on the Dronebot Workshop channel about running MicroPython on the new Raspberry Pi Pico boards. Bill was using Thonny, a Python IDE that is popular in the education community. Thonny was introduced in 2015 by Aivar Annamaa of the University of Tartu in Estonia. Thonny was designed to address common issues observed during six years of teaching Python programming classes to beginners. If you read about the project and its development, you’ll see that he’s put a lot of effort into making Thonny, and it shows.

            Leaning about Thonny got me curious, and after a little digging I discovered that it has WebREPL support for MicroPython right out-of-the-box. Although this is a new feature and classified as experimental, I found it reasonably stable to use and more than adequate for home lab use.

                In response, the UMN researchers posted an open letter apologizing to the community, followed a few days later by a summary of the work they did [PDF] as part of the “hypocrite commits” project. Five patches were submitted overall from two sock-puppet accounts, but one of those was an ordinary bug fix that was sent from the wrong account by mistake. Of the remaining four, one of them was an attempt to insert a bug that was, itself, buggy, so the patch was actually valid; the other three (1, 2, 3) contained real bugs. None of those three were accepted by maintainers, though the reasons for rejection were not always the bugs in question.

                The paper itself has been withdrawn and will not be presented in May as was planned…

                One of the first things that happened when this whole affair exploded was the posting by Greg Kroah-Hartman of a 190-part patch series reverting as many patches from UMN as he could find… As it happens, these “easy reverts” also needed manual review; once the initial anger passed there was little desire to revert patches that were not actually buggy. That review process has been ongoing over the course of the last week and has involved the efforts of a number of developers. Most of the suspect patches have turned out to be acceptable, if not great, and have been removed from the revert list; if your editor’s count is correct, 42 patches are still set to be pulled out of the kernel…

          • Q1 2021 ransomware trends: Most attacks involved threat to leak stolen data

            The vast majority of ransomware attacks now include the theft of corporate data, Coveware says, but victims of data exfiltration extortion have very little to gain by paying a cyber criminal.

            The stolen data has likely been held by multiple parties and not secured, and victimized organizations can’t be sure that it has been destroyed and not traded, sold, misplaced, or held for a future extortion attempt, they explained.

            Part 2: The Armis research team finds a new primitive to bypass firewalls using CVE-2021-24094, and provides a full analysis of this Windows TCP/IP stack vulnerability patched in February 2021.

            As detailed in the first part of this two-part blog series, several significant vulnerabilities in the Microsoft Windows TCP/IP stack were patched in Microsoft’s February 2021 Patch Tuesday. This blog series set out to do a deep dive on the vulnerabilities, analyzing their patches, and finding the root cause and the potential ramification of these vulnerabilities.

            • Confused Feds Subpoena Signal for Data It Doesn’t Collect

              For the second time in several years, Signal has been subpoenaed by federal investigators for data that the encrypted chat app company doesn’t actually collect.

            • Signal’s response to Homeland Security’s grand jury subpoena for user data is basically “You get nothing. You lose. Good day, sir”

              Signal, the popular messaging service with end-to-end encryption, stores precious little user data — “Unix timestamps for when each account was created and the date that each account last connected to the Signal service.”

              So when Homeland Security subpoenaed Signal to turn over “a wide variety of information… including the addresses of the users, their correspondence, and the name associated with each account,” Signal enlisted the aid of the ACLU, which replied to the FBI with a polite version of the Willy Winka “you get nothing” meme.

            • Signal’s response to a subpoena highlights value of encrypted messaging

              Last week we brought you news of Signal reverse engineering Cellebrite’s software and hardware and discovering a trove of vulnerabilities that it has no intention of exploiting.

              Today however Signal has shown us the value of choosing an encrypted messenger by way of a response to a subpoena from the United States Attorney’s Office in the Central District of California.

              Chromium-based Vivaldi has released an update with a new ‘Cookie Crumbler’ feature to alleviate the hassle of cookie consent forms that have plagued the web for Europeans due to its new privacy laws.

              As all Europeans know, whenever they open a web page they’re confronted with a message advising them that the site uses cookies for various reasons and then need to choose “I accept cookies” or “I refuse cookies” or, more often an option to “Manage Cookie Settings” or “Go to cookie settings”.

    A quick recommendation of KDE based on a reasonably recent (but not latest) build; there's this myth about KDE being difficult and flaky, but for a number of decades it has been the most advanced desktop (on any operating system) and its developers managed to hide the complexity while offering users all the power they may want/need

    The latest (if not last) person to garden the anti-RMS petition is an IBM employee. As has been the case for months. Another removal. IBM has a grudge against GNU's founder and by extension the FSF (they want the FSF to be a slave of IBM, just like the Linux Foundation is; we last covered this a day ago). “An open letter in support of Richard Matthew Stallman being reinstated by the Free Software Foundation” has meanwhile reached 6,750 signatures and that number grows by about 50 every 3-4 weeks, so it’s reasonable to expect 7,000 by year’s end. The anti-RMS petition may fall below 3,000.

  23. EPO ‘ViCo’ Prior Art (or ViCo Going Back to the 1980s)

    A previous post (video from yesterday) gave examples of prior art from the early/ier 1990s, debunking the EPO’s foolish and irrational embrace of this notion that so-called ‘ViCo’ is so absolutely incredible (we’ve kept talking, e.g. in many prior videos, about how the only real ‘innovation’ was connection speeds); MinceR recalls that “when UMTS (“3G”) was new, video calls on mobile was the feature that was supposed to sell the technology” and in the mid-80s you could already see who you spoke to (almost) in real time



  24. The European Data Protection Supervisor (EDPS) Needs to Get Its Act Together on the EPO's GDPR Violations

    EU authorities aren't keeping abreast of EPO abuses; as a result, people's basic rights and fundamental sense of dignity erode, with impunity resulting in passage of massive piles of data to foreign corporations and governments that engage in industrial and political espionage

    Debunking the EPO‘s Big Lie that ViCo is some sort of incredible and innovative thing that must therefore be embraced fully; the missing ingredient was fast network connections, so there’s no excuse for EPO claiming that we must embrace such stuff irrespective of the law, constitutions etc.
