        The Spanish-based company, Slimbook, has made available their next generation Slimbook Executive Linux ultrabooks with a 12th Gen Intel Alder Lake CPU.

        Slimbook, the company well known for producing KDE Plasma-powered laptops, has given their Executive series a bit of a refresh by making them available with the 12 Gen Intel Alder Lake CPU. This new iteration adds considerably more power (14 Cores, 20 threads, 24MB cache, and up to 4.80 GHz clock speeds), improved battery life, and better graphics (via an integrated Iris Xe 4K chipset). Consumers will find 2 different models available with this configuration: A 14" 3K display, running at a 90Hz refresh rate (at 2880 x 1800 resolution) and a 16" model that sports NVIDIA RTX 3050Ti graphics with 4GB GDDR6 RAM (also at a 90 Hz refresh rate).

      • MIT Technology ReviewThe US military wants to understand the most important software on Earth | MIT Technology Review

        Now DARPA, the US military’s research arm, wants to understand the collision of code and community that makes these open-source projects work, in order to better understand the risks they face. The goal is to be able to effectively recognize malicious actors and prevent them from disrupting or corrupting crucially important open-source code before it’s too late.

        DARPA’s “SocialCyber” program is an 18-month-long, multimillion-dollar project that will combine sociology with recent technological advances in artificial intelligence to map, understand, and protect these massive open-source communities and the code they create. It’s different from most previous research because it combines automated analysis of both the code and the social dimensions of open-source software.

        “The open-source ecosystem is one of the grandest enterprises in human history,” says Sergey Bratus, the DARPA program manager behind the project.

      • LinuxBuzHow To Remove Docker Images, Containers & Volumes - LinuxBuz

        Docker is an open-source tool that helps you to build, test and deploy applications in containerized environments. However, there are lots of unused containers, images, volumes, and networks that may reside in your system. They consume a significant amount of disk space of the host operating system. Docker does not remove those objects without cleaning up it manually.

        It is a good habit to clean up these unused disk spaces regularly and keep your system organized. Docker has several commands to clean up those unused objects.

        In this tutorial, we will show you how to remove Docker images, containers, and volumes.

        There are a lot of commands for running and managing a Docker container. If you are new to Docker then it is very difficult for you to deal with Docker commands. “Stop and remove all docker containers” is a day-to-day task of any Docker administrator. So it is essential for you to know how to remove and stop all docker containers. In this post, we will show you how to remove and stop all containers.

          It’s been an absolute mad dash this cycle porting Builder to GTK 4, but 43.alpha0 is out and available on GNOME Nightly.

          Builder is one of the larger applications within GNOME, especially if you include the libraries I had to write and maintain to make that possible. Porting an application to a new toolkit is always a big undertaking. However, it also provides an opportunity to rethink how major components work and simplify them while you’re there.

          So that is what has happened this cycle. It’s going to end up being a much more polished product due to the enormous amount of simplification going on.

          GTK 4 has simplified how a lot of things work and provided APIs that feel so obvious when you use them.

    • Linux Links10 Top Free and Open Source Lisp Web Frameworks

       Lisp (derives from “LISt Processing”) is one of the oldest programming languages. It was invented in 1958, with the language being conceived by John McCarthy and is based on his paper “Recursive Functions of Symbolic Expressions and Their Computation by Machine”. Over the years, Lisp has evolved into a family of programming languages. The most commonly used general-purpose dialects are Common Lisp and Scheme. Other dialects include Franz Lisp, Interlisp, Portable Standard Lisp, XLISP and Zetalisp.

      Here’s our recommended web frameworks for Lisp captured in a legendary Linuxlinks chart. We only feature free and open source software.

    • OpenSource.comHow one European bank embraces open source

       As the Development COE lead, I consider the expertise, structure and capabilities needed to make software development successful across hundreds of developers. We have roughly 600 people in the broader development team, but I'm not directly responsible for managing them. I'm responsible for defining how they will do their job. So for development best practices, standards unification and so on.

      Our transformation project. We have the current bank, which is built on typical legacy banking systems that are huge, distributed monolithic architecture systems. That is where most of our developers (around 400) are working day-to-day as it generates the bulk of the revenue for the bank.

      Alongside the legacy applications, we decided to completely modernize to something that we call "Digital Hub" which is replacing the bank's current infrastructure. The front-end applications are native mobile and web applications.

      • Improving Space Bar Functionality - GSoC'22 post #6

        On my weekly call with mentors today, I showed them how my Space bar works and I recieved some suggestions.

        One point of discussion was that clicking on a Space icon for first time resulted in noticeable delay before the UI was updated with filtered room list. The cause was traced to the latency introduced by /hierarchy api call.

      • Review and Updates for Merge Request - GSoC'22 post #7

        On July 9th, I created a merge request to submit all the work I did to add Space bar. The first issue was that CI builds failed because CI image has libQuotient 0.6 which doesn't support the Space /hierarchy call. As suggested by Tobias, getting around it was easy, as I could guard relevant code inside #ifdef QUOTIENT_07. This got the CI build passing.

      • OpenSource.com5 ways to learn C programming on Linux | Opensource.com

        There are many theories about why the C programming language has endured for as long as it has. Maybe it's the austerity of its syntax or the simplicity of its vocabulary. Or maybe it's that C is often seen as a utilitarian language, something that's rugged and ready to be used as a building material for something that needs no platform because it's going to be its own foundation. C is clearly a powerful language, and I think its longevity has a little something to do with the way it serves as a springboard for other popular technologies. Here are five of my favorite technologies that utilize and rely upon C, and how they can each help you learn more about C yourself.

        • Network World[Old] Open-sourced tool speeds up Linux scripts via parallelization

          Researchers have open-sourced pa.sh (also called pash), a tool that can dramatically speed up Linux scripts by using parallelization, saving time and without risk of introducing errors.

          The process of parallelization first examines a script for code that can be run separately and independently, so not all scripts can benefit from the tool. But when pa.sh does find portions that can run independently, it runs them in parallel on separate CPUs. It also uses other techniques to get the code to run faster.

        • Copying previous commands with fzf and zsh

          Sometimes I want to copy a command I previously typed on my shell to the clipboard. It may be for documentation, note taking, writing a script, setting up an Ansible playbook, sending to someone… You name it.

    • IBM Old TimerThe Potential Impact of Web3 on the Internet and the Digital Economy [Ed: Buzzwords and hype spewed out by former IBM chief]

      A few weeks ago, the Blockchain Research Institute (BRI) announced that its annual global conference would be renamed Web3 Blockchain World, and that the Enterprise Blockchain Awards would now be called the Web3 & Blockchain Transformation Awards.

      I’ve been affiliated with BRI for a number of years as a research contributor and as chair of its blockchain awards committee. I was somewhat concerned with the name change, because, as is generally true of new technologies in their early stages, there are multiple views of what web3 is all about. Critics view web3 as little more than hype, a rebranding effort to shed some of the cultural and political baggage of crypto, while supporters believe that web3 represents the future of the internet, upending traditional gatekeepers and ushering a middleman-free digital economy.

      • 5 Tricky Container Security Challenges - Container Journal

        Containerized environments can be relatively complex to secure, particularly for enterprise teams used to more traditional network security processes and strategies. There was initial optimism that containerized infrastructure would actually be more inherently secure because microservices are limited in function and can be hardened. The reality, though, has proved otherwise.

        Here are five reasons why securing container and Kubernetes environments requires new approaches that must diverge from—and go beyond—traditional security capabilities.

        • PoliticoChina Direct: A hawk for No. 10? — Xi mulls extra title — TikTok in trouble

          China is selling less to Russia, but buying from its internationally-isolated neighbor at an “elevated pace.” That’s according to a Reuters analysis of the latest figures issued by the Chinese customs authorities. Chinese imports from Russia jumped 56 percent in June versus the same month a year ago, in addition to a surge of 80 percent in May. Much of it is thanks to China’s energy needs, particularly in oil and gas. On the other hand, Chinese businesses appear cautious when it comes to selling things to Russia — partly because of Russia’s dire economic situation, but also out of concerns about such activities attracting the (threats of) sanctions from the West. Getting energy from Russia, after all, is not sanctionable. Just look at Germany, which says it will keep buying Russia oil until 31 December.

          IN HOT WATER: Italy’s data protection authority has warned TikTok that it may have breached EU privacy laws with its plan to use personal data stored on users’ devices for personalized ads without explicit consent, my colleague Antoaneta Roussi reports.

          The issue: In an update to its privacy policy, TikTok, which is owned by Chinese company ByteDance, informed users that starting yesterday (July 13), those over the age of 18 would be targeted by personal advertizing based on their behavior on the app. The legal basis for processing the data would no longer be consent, but rather the “legitimate interest” of TikTok and its partners, the company announced.

          A fast-tracked investigation by the Italian authority found that TikTok’s policy was incompatible with the European e-Privacy Directive, which requires individual consent for access to information on a user’s device. It also notified the European Data Protection Board and the Irish privacy authority (which formally oversees TikTok in Europe) to consider further action since the move was incompatible with the European General Data Protection Regulation.

    • Censorship/Free Speech

      • WiredTwitter’s Case in India Could Have Massive Ripple Effects [Ed: Twitter is all about censorship but for political reasons it pretends otherwise]

        IN JUNE, TWITTER received an ultimatum from the Indian government to remove some 39 accounts and content from its platform. Sources familiar with the order say it outlined that if Twitter refused to comply, its chief compliance officer could face criminal proceedings. They say it also stated that the company would lose its “safe harbor” protections, meaning it would no longer be protected from liability for the content created by its own users. This is an escalation of a series of “blocking orders,” or content removal orders, sent by the Indian Ministry of Electronics and Information Technology, which have increased significantly in the past 18 months.

        Last week, Twitter responded: It will take the Indian government to court.

        While the dispute itself deals with only specific accounts and pieces of content, experts told WIRED that its outcome could have major repercussions, and serve as a “bellwether for this ongoing battle about internet freedom,” says Allie Funk, research director for technology and democracy at Freedom House.

        • Is 16KB enough?

          Quite everyone agrees that nowadays you need a several megabyte internet speed, or if you're privileged you have several hundred megabytes. But what for?

          The internet got gradually faster, while the websites got gradually slower and more bloated. Even if you have a decent internet connection by today's standards, try loading any "modern" website and you'll wait a good dozen of seconds, then you will be bombarded with ads and trackers.

          This is why I've switched to text-based browsers. Aside from obvious advantages like no ads, cookies, javascript etc. I don't participate in any monopoly either. I currently fluctuate between w3m and lynx, both with their pros and cons. Nonetheless, I mostly browse Gemini than use HTTP.
