        After completing a DIY Raspberry Pi Zero 2 W handheld PC earlier this year, Penk Chen has designed another, rather odd but cool-looking, DIY computer. The “Mainboard Terminal” is a retro-style computer with a round display powered by the mainboard found in Framework modular laptop.

        The computer has been tested to work with Ubuntu 22.04 out of the box with just a few configuration tweaks for the display, but other operating systems should also work considering the mainboard is based on an Intel Core i5-1135G7, i7-1165G7, or i7-1185G7 Tiger Lake processor.

        • Multiple syncobjs support for V3D(V) (Part 1) | Wen.onweb

          As you may already know, we at Igalia have been working on several improvements to the 3D rendering drivers of Broadcom Videocore GPU, found in Raspberry Pi 4 devices. One of our recent works focused on improving V3D(V) drivers adherence to Vulkan submission and synchronization framework. We had to cross various layers from the Linux Graphics stack to add support for multiple syncobjs to V3D(V), from the Linux/DRM kernel to the Vulkan driver. We have delivered bug fixes, a generic gate to extend job submission interfaces, and a more direct sync mapping of the Vulkan framework. These changes did not impact the performance of the tested games and brought greater precision to the synchronization mechanisms. Ultimately, support for multiple syncobjs opened the door to new features and other improvements to the V3DV submission framework.

        • Multiple syncobjs support for V3D(V) (Part 2) | Wen.onweb

          In the previous post, I described how we enable multiple syncobjs capabilities in the V3D kernel driver. Now I will tell you what was changed on the userspace side, where we reworked the V3DV sync mechanisms to use Vulkan multiple wait and signal semaphores directly. This change represents greater adherence to the Vulkan submission framework.

          I was not used to Vulkan concepts and the V3DV driver. Fortunately, I counted on the guidance of the Igalia’s Graphics team, mainly Iago Toral (thanks!), to understand the Vulkan Graphics Pipeline, sync scopes, and submission order. Therefore, we changed the original V3DV implementation for vkQueueSubmit and all related functions to allow direct mapping of multiple semaphores from V3DV to the V3D-kernel interface.

      • Its FOSSHydraPaper: A Wallpaper Manager for Linux with Multi-Monitor Support


        By default, you get the ability to set wallpapers as per the desktop environment on your Linux distribution.

        And, it is often limiting when trying to add a custom folder of wallpaper collection to the available selection. Moreover, when it comes to multi-monitor setup, you do not get the ability to choose separate wallpapers in your distro. So, you need to head out looking for a Graphical User Interface (GUI) program that lets you do that.

        • Red Hat OfficialThe new standard: Red Hat In-Vehicle Operating System in modern and future vehicles

          Open source has long been a force multiplier for innovation. Time and time again, operating in the open source way has proven that the power of many is stronger than the power of few. This sentiment is at the heart of everything we do at Red Hat, most notably in our collaboration with General Motors to advance software-defined vehicles at the edge, announced today by Matt Hicks, Executive VP, Products & Technologies, Red Hat, at Red Hat Summit.

          Today’s sophisticated use cases, such as advanced driver-assistance systems (ADAS), pose a challenge for the development of current vehicle platforms. Lack of a modernized and consistent infrastructure means less design reuse across vehicle lines and model years, and system limitations make future software updates costly and difficult. Adopting open source software in lieu of proprietary operating systems can introduce an avenue for establishing common standards and fosters an ecosystem of Linux-savvy automotive developers. By utilizing open source software, the automotive industry can help alleviate many of these issues and as a result, modernize their strategies while meeting customers’ present-day needs.

          Like “digital transformation” and “DevOps,” the term “agile” has come to mean many things to many different people in software development and project management. The principles of agile software development are generally straightforward: They prioritize customer collaboration, flexibility to change, individual empowerment, and creating working software rather than extensive documentation.

          [...]

          At its core, agile is a human-centric methodology. While it can be much easier to build support and enthusiasm for new technologies or software, it’s more important in the long term to frame agile as a cultural transformation. Scrums and kanbans are the tools that allow teams to pursue agile development, but the more important transformations take place at the human level.

        • Red HatManage cluster resources efficiently with Red Hat OpenShift | Red Hat Developer

          To adapt to cloud-native trends, developers must have multiple perspectives on their distributed systems. In particular, they need to understand how their code will smoothly integrate with infrastructure configurations. As the complexity of a microservices architecture evolves, traffic load and cluster use both also increase, which influences development practices at the team level.

        • Red Hat6 design tips for Java microservices development

          As Java developers, we have been using Java bean objects to store our data for nearly the entirety of the language’s existence. It has always been considered a good practice to have private member variables along with public getters and setters for those private member variables. Furthermore, after two decades of Java EE and now Jakarta, it’s become common to put all of our classes in four or five packages or folders that loosely map to model, view, and controller packages or folders. For good measure, you might add a package for data transfer objects and other classes.

          With the explosion of complexity in the number and kinds of annotations required to make modern microservices work, this pattern of a few packages and hundreds of files in each folder is fundamentally broken when it runs up against the finite capabilities of humans. How many times have you scrolled for a long time looking for the four files that make up the business logic that you are trying to update?

          There is a better way. I explore it in detail in 10 design tips for microservices developers with Quarkus, my on-demand session from Red Hat Summit 2022. In this article, we’ll take a look at some of the high points.

        • [RFC PATCH] ubd: add io_uring based userspace block driver – Ming Lei (Red Hat)
          This is the driver part of userspace block driver(ubd driver), the other
          part is userspace daemon part(ubdsrv)[1].
          
          The two parts communicate by io_uring's IORING_OP_URING_CMD with one
          shared cmd buffer for storing io command, and the buffer is read only for
          ubdsrv, each io command is indexed by io request tag directly, and
          is written by ubd driver.
          
          For example, when one READ io request is submitted to ubd block driver, ubd
          driver stores the io command into cmd buffer first, then completes one
          IORING_OP_URING_CMD for notifying ubdsrv, and the URING_CMD is issued to
          ubd driver beforehand by ubdsrv for getting notification of any new io request,
          and each URING_CMD is associated with one io request by tag.
          
          After ubdsrv gets the io command, it translates and handles the ubd io
          request, such as, for the ubd-loop target, ubdsrv translates the request
          into same request on another file or disk, like the kernel loop block
          driver. In ubdsrv's implementation, the io is still handled by io_uring,
          and share same ring with IORING_OP_URING_CMD command. When the target io
          request is done, the same IORING_OP_URING_CMD is issued to ubd driver for
          both committing io request result and getting future notification of new
          io request.

          When the Formula One grand prix went to Hungary, they faced a big problem: prostitution was illegal. This is a challenge for events with a predominantly male audience. Hungary changed their laws and even constructed Erotik Camping zones for diversity purposes.

          We already exposed the segregated accommodation at DebConf22 and now we will penetrate deeper into the issue.

          The last DebConf in Europe was DebConf16 in Heidelberg, Germany. It was the biggest DebConf ever with over 700 participants. Participants attend between one and two weeks, up to 17 or 18 days for some people. Participation is over 98 percent male.

          DebConf Kosovo originally planned to be in the capital city, Prishtina. The organizers subsequently decided to move it to a much smaller city, Prizren. The main reason for this move is to be inaccessible.

          Debian has banned people like Linus Torvalds. They want to have DebConf concealed within the walls and gates of a former military base just in case Linus or any other censored speaker decides to show up.

          This is going to interest a lot of people… EasyOS built with Debian DEB packages has the advantage of access to a huge repository. There was an “Easy Buster”, now retired, and all effort since then has been on “Easy Dunfell” which is built with packages compiled in OE. The Dunfell-series is “lean and mean”, that is, small and optimized; however, the package repository is small.

      • Russell CokerRussell Coker: Elon and Free Speech

        Elon Musk has made the news for spending billions to buy a share of Twitter for the alleged purpose of providing free speech. The problem with this claim is that having any company controlling a large portion of the world’s communication is inherently bad for free speech. The same applies for Facebook, but that’s not a hot news item at the moment.

        If Elon wanted to provide free speech he would want to have decentralised messaging systems so that someone who breaks rules on one platform could find another with different rules. Among other things free speech ideally permits people to debate issues with residents of another country on issues related to different laws. If advocates for the Russian government get kicked off Twitter as part of the American sanctions against Russia then American citizens can’t debate the issue with Russian citizens via Twitter. Mastodon is one example of a federated competitor to Twitter [1]. With a federated messaging system each host could make independent decisions about interpretation of sanctions. Someone who used a Mastodon instance based in the US could get a second account in another country if they wanted to communicate with people in countries that are sanctioned by the US.

      • FSFEFSFE calls for digital sustainability in the telecom sector

        As a contribution to a consultation organised by the European telecom regulator, BEREC, the FSFE calls for increasing the level of digital sustainability in the telecommunications sector by safeguarding device neutrality and establishing the right to install any software on any device.

        Last month BEREC, the European telecommunications regulator, organised a public consultation on a report about the impact of the telecommunications sector on the environment. The report is an initiative to assess and better understand the impact of the digital sector, including electronic communications networks and services, on the environment and to set an outline for BEREC activities in support of environmental sustainability of the sector.

        The FSFE took part in the consultation as a civil society stakeholder with years of experience in digital sustainability. Our position offered recommendations that could be further used to improve environmental transparency and data accuracy on the telecom sector’s environmental footprint by developing regulatory frameworks to safeguard and promote software and hardware sustainability. FSFE’s position in this consultation was aligned with the publication of the Open Letter “The universal right to install any software on any device”, co-signed by more than 45 organisations, demanding the universal right to install any software on any device. Publication of source code of drivers, tools, and interfaces is fundamental for extending devices’ lifespan.

            This year, 2022, May the 4th was my last day at Mozilla.

            [...]

            I started on July 2, 2013 on a 6 months contract at Mozilla to work on Firefox OS on Web Compatibility issues. I was living in Montréal, Canada at the time.

            [...]

            I was not alone. The success of a project never relies on a single individual, but a full team of people dedicated to make this mission a reality. At the very beginning, we were three coming from Opera Software, we all had an experience on Web compatibility issues: Mike Taylor, Hallvord R.M. Steen and me. Then Adam Stevenson joined. None of the initial team is still at Mozilla. I miss working with Eric Tsai too. Some people (open contributors) have also participated to the project like Abdul Rauf, Alexa Roman, Kate Manning, Guillaume Demesy, Reinhart Previano.

            webcompat.com was setup on purpose without Mozilla branding to invite the participation of all browser implementers (Apple, Google, Microsoft, Opera, etc.) on solving issues resulting from website mistakes or interoperability issues. Mozilla put the main effort into it and in return webcompat.com helped Mozilla and Firefox Core team to fix a lot of issues.

            [...]

            Emilio Cobos Álvarez, Daniel Holbert, Jonathan Kew, Masayuki Nakano, Makoto Kato, Brian Birtles, Boris Zbarsky, Hiroyuki Hikezoe, Botond Ballo, Olli Pettay, Henri Sivonen, Anne van Kesteren, Ting-Yu Lin, Cameron McCormack. These lists are dangerous, I keep forgetting people.

            I could talk about all the things which have been solved around text input, CSS flexbox, JavaScript features, DOM and SVG, … but this starts to be long.

        • OpenSource.com6 easy ways to make your first open source contribution with LibreOffice


          “Getting involved” with open source can seem a little confusing. Where do you go to get started? What if you don’t know how to code? Who do you talk to? How does anybody know that you have contributed, and besides that does anybody care?

          There are actually answers to questions like those (your choice, it’s OK, nobody, you tell them, yes) but during the month of May 2022, there’s one simple answer: LibreOffice. This month is a month of participation at LibreOffice and its governing body, The Document Foundation. They’re inviting contributors of all sorts to help in any of six different ways, and only one of those has anything at all to do with code. No matter what your skill, you can probably find a way to help the world’s greatest office suite.

        • OpenSource.comHow to (safely) read user input with the getline function | Opensource.com

          Reading strings in C used to be a very dangerous thing to do. When reading input from the user, programmers might be tempted to use the gets function from the C Standard Library. The usage for gets is simple enough:

          char *gets(char *string);

          That is, gets reads data from standard input, and stores the result in a string variable. Using gets returns a pointer to the string, or the value NULL if nothing was read.

          [...]

          Note that the string includes the delimiter character. For getline, the delimiter is the newline, which is why the output has a line feed in there. If you don’t want the delimiter in your string value, you can use another function to change the delimiter to a null character in the string.

          With getline, programmers can safely avoid one of the common pitfalls of C programming. You can never tell what data your user might try to enter, which is why using gets is unsafe, and fgets is awkward. Instead, getline offers a more flexible way to read user data into your program without breaking the system.

        • OpenSource.comMy open source journey with C from a neurodiverse perspective | Opensource.com

          I was born in 1982, which in human years is only 40 years in the past (at the time of writing). In terms of computer development, it’s eons ago. I got my first computer, a Commodore 64, when I was ten years old. Later, I got an Amiga, and by 13 I got an “IBM Compatible” (that’s what they were called, then) PC.

          In high school, I did a lot basic programming on my graphing calculator. In my second year of high school, I learned basic C programming, and in my third year I started doing more advanced C programming, using libraries, pointers, and graphics.

    • Interesting Times

      The old proverb “may you live in interesting times” has been going through my mind for the past couple years, and more often in the past few months. Between pandemics, historic economic crashes, bull runs, and crashes again, war, climate change, record breaking weather, the ever encroaching threat of climate change, and the general apparent downward spiral of American society in general, it’s hard to find anything to be optimistic about.

              In the last #PrivacyofthePeople post, we looked at the conflict between efficiency and privacy posed by the use of cookies that raise concerns about user privacy and data collection. In this post, we plan to examine whether the police can check your mobile phone devices even if you do not consent to it. Presently, there is no legal provision which would allow for such random checking of mobile phones. However, since the law is still trying to catch up to regulating new technology, old laws are being interpreted widely to allow police officials to gain access to our devices. Here, even the pending Data Protection Bill, 2021 (in its present form) fails to provide sufficient safeguards.

  2. EPO Eating Its Own (and Robbing Its Own)

    António Campinos is lying to his staff and losing his temper when challenged about it; Like Benoît Battistelli, who ‘fixed’ this job for his banker buddy (despite a clear lack of qualifications and relevant experience), he’s just robbing the EPO’s staff (even pensioners!) and scrubbing the EPC for ill-gotten money, which is in turn illegally funneled into financialization schemes



  3. [Meme] EPO Budget Tanking?

    While the EPO‘s António Campinos incites people (and politicians) to break the law he’s also attacking, robbing, and lying to his own staff; thankfully, his staff isn’t gullible enough and some MEPs are sympathetic; soon to follow is a video and publication about the EPO’s systematic plunder (ETA midnight GMT)



  4. EPO.org (Official EPO Site) Continues to Promote Illegal Agenda and Exploit Ukraine for PR Stunts That Help Unaccountable Crooks

    epo.org has been turned into a non-stop propaganda machine of Benoît Battistelli and António Campinos because the EPO routinely breaks the law; it’s rather tasteless that while Ukrainians are dying the EPO’s mob exploits Ukraine for PR purposes



  5. [Meme] EPO Applicants Unwittingly Fund the War on Ukraine

    As we’ve just shown, António Campinos is desperately trying to hide a massive EPO scandal



  6. EPO Virtue-Signalling on the Ukrainian Front

    António Campinos persists in attention-shifting dross and photo ops; none of that can change the verifiable facts about the EPO’s connections to Lukashenko’s 'science park' in Minsk

    Unhappy with the law-breaking autocracy (the EPO‘s management breaks the law as a matter of routine), fast-deteriorating working conditions and rapidly-decreasing quality of work (or lack of compliance with the law), workers have escalated further, topping off strikes and industrial actions with a large-scale petition
