      • Big Data on Kubernetes: The End For Hadoop?

        When data sets are too large and/or too complex for traditional software to deal with, we refer to them as ‘big data.’ Organizations and businesses around the world need to use big data to work on projects that influence the way we live now and in the future.

        Conversational AI companies want their bots to seem as natural as possible. To achieve this, they must process massive amounts of data in the most efficient and cost-effective way possible. That’s where open source ecosystems like Hadoop come in.

      • Traefik Labs Adds Hub to Simplify Container Networking – Container Journal

        Traefik Labs today unveiled a cloud service that leverages agent software to simplify the provisioning of network services for containers.

        Manuel Zapf, a product manager for Traefik Labs, says Traefik Hub is a software-as-a-service (SaaS) platform that adds an agent to the open source Traefik Proxy software. That agent makes it possible to instantly authorize access to containers from a single dashboard. That capability eliminates the need to manually configure domain name system (DNS) addresses, routing rules, access control and network access translation to gain access to the internet, he adds.

        Once more, at The Linux Foundation’s Open Source Summit, Cardano’s chief open source officer Dirk Hohndel and Linux creator Linus Torvalds had a wide-ranging conversation about Linux development and related issues.

        Torvalds, who hates public speaking, said that he always does these presentations as interviews because, “I do software. I don’t do public speaking.” The hindrance being, he explained, “I don’t know what people are interested in. So, Dirk asks the questions and, hopefully, if he asks bad questions, it’s not my fault.”

      • The Register UKGraphical desktop system X Window turns 38 • The Register

        The X window system turned 38 years old this week, and although it has more rivals than ever, it is still the go-to for a graphical desktop on Unix.

        The first public release of the X window system, according to Robert W. Scheifler’s announcement, was 19 June 1984.

        X itself was a rewrite of an older windowing system called W, which ran on a research microkernel OS called the V-System (V→W→X, you see.) Both the V-System and the W window system seem to have now been lost, although Bryan Lunduke has an interesting history.

        About the only relic that you can see today, if you’re curious, is the V-System manual [PDF].

        Just two years after launch, X had already reached version 10 – the oldest point release showing in the release history on the X.org Foundation web page. X11R1 was introduced in 1987, and with some modifications, that’s what the world is still using today.

        That is quite a feat of longevity, considering that that’s the same year as OS/2 1.0 came out, as well as Acorn’s Archimedes range.

      • DedoimedoXnView – Small, feisty and powerful

        XnView is a fantastic program, overall. There are some bugs and problems, of course. In my Plasma desktop, the UI didn’t render perfectly – some icons were low-res, some buttons didn’t have all the border lines and such. The installation comes with a bogus dependency warning, and the program can be overwhelming to new users, due to its myriad options and settings and somewhat confusing Browser mode.

        That said, once you settle in, and you invest a little bit of time taming the tool, XnView can look and behave the part. You can also adjust its shortcuts for a much more efficient work session, you have tons of filters and effects, plus you can work with image metadata, and there’s a tabbed interface to boot. ‘Tis a pretty solid program, with lots of great features. I still do find some elements a bit clunky, or not as fast or efficient as I’d like them. That said, IrfanView aside, this is one of the more capable and useful image viewers out there. You should definitely check it out. And with that, I bid you farewell.

        Learn the steps and commands to install the latest version of Apache Tomcat on Ubuntu 22.04 LTS Jammy JellyFish Linux to test various Java-based applications…

        Apache Tomcat is an open-source web server that allows you to run web applications written in Java. Tomcat is developed and maintained by a free community of developers and our Apache license is published as open-source software.

        Well, Tomcat is significantly different from the Apache web server, it was developed to primarily focus on Web applications. Tomcat does not understand URLs as a file specification, but as a notification of a user action. This is comparable to event-driven programming in classic GUI programming: a click on a button generates an event that the window manager reports to the program. Calling up a URL is analogous, be it in the form of a link or a form called.

      • Linux Shell TipsHow to Change File Permissions in Linux Systems

        Being an expert user or administrator of a Linux operating system environment requires us to have a mastery of Linux file management. Everything under the Linux operating system environment is regarded as a file, from created or existing files and folders to internal or external hardware devices like USB devices.

        Linux file management accounts for a larger proportion of the Linux OS operations and starts at a folder/directory level. Linux adheres to a tree-like structure with a base directory that leads to other sub-directories or sub-folders used to maintain created or already-existing files.

      • H2S MediaHow to increase Swap Space in Ubuntu 22.04 LTS Jammy – Linux Shout

        Add the required Swap Space in Ubuntu 22.04 LTS Jammy JellyFish Linux, if you think the existing one is not enough on your Server or Desktop system. Users can also follow this tutorial for Ubuntu 20.04 LTS as well.

        Linux (like almost all other operating systems) tries to keep the operating system components, currently required program data, etc. in RAM (main memory), since the access to the RAM is much faster than to data carriers such as hard disk, CD, or USB stick.

        However, RAM has its limit of volatile space, if your system has 4GB of memory then it can happen many times your RAM space is allocated completely when we run many programs simultaneously. At this point, the Linux kernel begins to free up RAM by writing parts of the data stored in RAM to the hard disk, the portion of the hard disk that is dedicated to this is called “Swap” memory. If the data is needed again, it is loaded back into RAM and other data that is not needed at the moment is written to the swap. In such a case, it is also said: that “the system swaps”.

      • Fedora MagazaineUsing Linux System Roles to implement Clevis and Tang for automated LUKS volume unlocking – Fedora Magazine

        One of the key aspects of system security is encrypting storage at rest. Without encrypted storage, any time a storage device leaves your presence it can be at risk. The most obvious scenario where this can happen is if a storage device (either just the storage device or the entire system, server, or laptop) is lost or stolen.

        However, there are other scenarios that are a concern as well: perhaps you have a storage device fail, and it is replaced under warranty — many times the vendor will ask you to return the original device. If the device was encrypted, it is much less of a concern to return it back to the hardware vendor.

        Another concern is anytime your storage device is out of sight there is a risk that the data is copied or cloned off of the device without you even being aware. Again, if the device is encrypted, this is much less of a concern.

        Fedora (and other Linux distributions) include the Linux Unified Key Setup (LUKS) functionality to support disk encryption. LUKS is easy to use, and is even integrated as an option in the Fedora Anaconda installer.

        The separation means that it looks exactly like a frugal install in the image file. This makes it conceptually very simple for someone to see how to do a frugal install into an internal drive.
        EasyOS no longer knows anything about the boot manager or bootloader that caused it to boot. The boot-partition variables BOOT_UUID, BOOT_DEV and BOOT_DIR are no longer in EasyOS. All that Easy knows about is where it is installed, in the working-partition, variables WKG_UUID, WKG_DEV and WKG_DIR.

        We all know how running a command in the Debian command line, the Terminal, results in the execution of the command and printing of the results, if any, in the Terminal itself. Sometimes, this immediate display of output is not enough, especially if we want to save the output for later use. Fortunately, the Linux bash and all operating system bash, for that matter, is equipped with the ability to print the output of a command to a specified file. In this article, we will work on the following two scenarios…

While it was mostly true for earlier syslog-ng releases, for recent syslog-ng releases (3.34+) the disk-buffer file can stay large even when it is empty. This is a side effect of a recent syslog-ng performance tuning.

      • Red HatMeasuring BPF performance: Tips, tricks, and best practices | Red Hat Developer

        Measuring stuff is harder than you may think. Even in math, there is such a thing as non-measurable sets and Banach-Tarski paradox, which shows that a three-dimensional ball of radius 1 can be dissected into 5 parts, which can be magically reassembled to form two balls of radius 1. Now imagine what kind of mess we’ve got in software engineering.

        This may sound somewhat philosophical, so let’s get down to earth and talk about BPF programs. BPF, which originally stood for Berkeley Packet Filter, is a general-purpose execution engine that can be used for a variety of purposes, including networking, observability, and security. What we’ll be discussing in this article was initially called extended BPF (eBPF) to differentiate from the classic BPF, but now this technology is often referred to as just BPF, and that’s what we’ll call it here.

        Having full visibility throughout the systems we build is a well established best practice. Usually, one knows which metrics to collect, and how and what to profile or instrument to understand why the system exhibits certain levels of performance. But all of this becomes more challenging as soon as the BPF layer is included. Despite years of development, it is still a black box in many ways.

        But do not despair: this article will show, with some amount of creativity, that one can reveal what is going on under the hood. The article will begin with a userspace service that uses BPF programs attached to various syscalls to inspect system activity. It does the job, but what we really want is to understand the overhead of the BPF programs themselves. How do you look inside? That’s the problem that we will ultimately tackle.

      • The Register UK21.3 of Arch Linux derivative Manjaro released • The Register

        Version 21.3 of Manjaro – codenamed “Ruah” – is here, with kernel 5.15, but don’t let its beginner-friendly billing fool you: you will need a clue with this one.

        Manjaro Linux is one of the more popular Arch Linux derivatives, and the new version 21.3 is the latest update to version 21, released in 2021. There are three official variants, with GNOME 42.2, KDE 5.24.5 or Xfce 4.16 desktops, plus community builds with Budgie, Cinnamon, MATE, a choice of tiling window managers (i3 or Sway), plus a Docker image.

        The Reg took its latest look at Arch Linux a few months ago. Arch is one of the older rolling-release distros, and it’s also famously rather minimal. The installation process isn’t trivial: it’s driven from the command line, and the user does a lot of the hard work, manually partitioning disks and so on.

        Changes were numerous and all over the place, the base of the system for example, was built on a new Glibc 2.35, GCC 11.3.0, and Binutils 2.38 based Toolchain. Further updates in Core included DBus 1.14.0, Systemd 250.7, Nettle 3.8 and the kernel moved to 5.17.15.
        Midna, the Plasma theme used in KaOS received some changes (partly to get ready for Plasma 5.25), visual biggest change is the addition of a well-integrated virtual keyboard in the login & lock screen.

        KaOS 2022.06 comes with the latest Plasma 5.25, the latest KDE Frameworks 5.95, and the newest app set provided by KDE Gear 22.04.

        KaOS is an independent rolling-release distribution inspired by Arch Linux that includes the latest KDE Plasma Desktop and related Qt Toolkit-based software.

        Unlike most other Linux distros, KaOS does not provide various installation images with GNOME, Xfce, LXQt, or any other desktop. In other words, the distro is solely dedicated to the KDE Plasma desktop.

        The distro uses Pacman as its package manager but does not rely on software repositories developed and maintained by Arch Linux. Instead, the software is available from in-house repositories and is built exclusively for 64-bit machines.

        I have written about using PipeWire previously where I did have a very positive experience with it. Unfortunately, I did have some irritating quarks with it that ultimately resulted in my going back to using PulseAudio on my openSUSE Tumbleweed machines. They were little things needing to refresh the browser after a Bluetooth device changed status. I decided it was time to try PipeWire again when PulseAudio started to give me random Bluetooth audio device issues where the device, after connecting, would not become available.

        I have heard about many of the improvements that had come to PipeWire and decided that now was the time to try it out again. I revisited the directions I had previously put together on the installation process and sure enough it worked. I did have to make one modification to it. I added a now new module called pipewire-aptx which is the Bluetooth aptX codec plugin.

        If you have an installation of openSUSE Tumbleweed that is using the PulseAudio sound server, the command is quite simple to execute in the terminal to switch you over. I have tested and verified this on multiple machines with success.

        The company says it’s a highly scalable real-time, deterministic, 32-bit embedded CPU, that is feature-rich and flexible in design for mainstream devices, but, excuse the pun, leaves most of the details to your imagination…

      • ArduinoMonitoring IV fluid bag levels with the Arduino Portenta H7 and Vision Shield

        When a patient is receiving intravenous (IV) fluids, it is vital that air is not introduced into the line, as its presence can create issues such as excessive pressure or even embolisms that can be life-threatening. Normally, the level of fluids remaining within the bag is periodically checked by a nurse, but due to challenges related to staffing, this might not be enough. Therefore, Manivannan Sivan devised an automated monitoring system that uses computer vision along with machine learning to do this repetitive task instead of a person.

        To begin the project, Sivan gathered a series of images that spanned three categories with an Arduino Portenta H7 and Vision Shield. Within each picture, the IV fluid bag is 15cm away and contains either an adequate, less than 50%, or low level of fluid remaining. Once trained, his model was able to successfully recognize the correct level around 96% of the time, although additional images taken at different light levels would help improve the accuracy even more.

      • CNX SoftwareESP32-C5 RISC-V IoT MCU supports dual-band WiFi 6, Bluetooth 5.0 LE – CNX Software

        Espressif Systems ESP32-C5 is an upcoming wireless RISC-V microcontroller for IoT applications that supports dual-band (2.4 & 5.0 GHz) WiFi 6 connectivity as well as Bluetooth 5.0 LE.

        It is the first dual-band processor from Espressif, as while the Shanghai-based company previously announced the ESP32-C6 WiFi 6 and Bluetooth 5 LE RISC-V SoC last year, it only supports 2.4 GHz frequency. Note it’s not the first dual-band WiFi 6 IoT chip on the market as NXP introduced the IW612 Wi-Fi 6, Bluetooth 5.2, 802.15.4 tri-radio solution last January, but ESP32-C5 should target different use cases.

      • Sourceware – GNU Toolchain Infrastructure roadmap

        Sourceware, https://sourceware.org/, is community run infrastructure, mailinglists, git, bug trackers, wikis, etc. hosted in the Red Hat Open Source Community Infrastructure Community Cage together with servers from e.g. Ceph, CentOS, Fedora and Gnome.

        Sourceware is mainly known for hosting the GNU Toolchain projects, like gcc at https://gcc.gnu.org/, glibc, binutils and gdb. But also hosts projects like annobin, bunsen, bzip2, cgen, cygwin at https://cygwin.org/, debugedit, dwz, elfutils at http://elfutils.org, gccrs, gnu-abi, insight, kawa, libffi, libabigail, mauve, newlib, systemtap and valgrind at https://valgrind.org/.

        A longer list of Sourceware projects, those without their own domain name, including several dormant projects, can be found here: https://sourceware.org/mailman/listinfo.

        Most of these projects use a email/git based workflow using mailinglists for discussing patches in preference to web based “forges”.

    • Tedium10 Social Networks That Didn’t Make It

      The website Orkut.com is a site you’ve probably visited even if it feels like a vague memory today. It is Google’s first attempt at a social network, and one that became a success largely by chance; it started with modest goals and grew pretty quickly, although it never reached Facebook scale. Named for its creator, Orkut Büyükkökten, the network surged for a time, but eventually fell into decay, eventually going offline in 2014. After a few years of attempting to build a follow-up network, Orkut is back on that original domain, promising a follow-up. “I’ve always believed that a friendship is more than a friend request, and I have dedicated my life to helping millions of you build authentic connections with your neighbors, family members, employees and the beautiful strangers who come into your lives,” he wrote. You kind of want to root for Orkut Büyükkökten, knowing that the odds are against him in reviving this old social network in a new way. But it’s in his spirit that I shine the “didn’t make it” list on social media. Even if the community is dead, the people that made it are still worth discussing.

    • On Hork-Bajir language

      Someone whose blog I follow has been posting about how the portrayal of the Hork-Bajir in Animorphs isn’t really internally consistent. If you’re unfamiliar, they’re these huge biped dinosaur-bird guys. No feathers, but they have horns on their heads and blades growing out of their arms and legs.

      (They’re pacifist herbivores. The blades are for stripping bark from trees to eat.)

      And they’re portrayed as this kind of stupid, noble-savage stereotype. Except for the once-in-a-generation mutation they call “seers”, who have intelligence on par with the ~smart~ species in the series. One weird moment in “The Hork-Bajir Chronicles” is when the seer Dak Hamee is making little stick-drawings in the ground and tells his friend Jagil Hullan “hey look it’s you” and Jagil is like “what no that’s not me, I’M me”. The whole conceit of the book is that a Hork-Bajir is telling this story to one of the Animorphs! Can they or can they not recognize representations?

        It has been a little more than two years since the CHIPS for America Act , which would strengthen the U.S. semiconductor industry act, was proposed, but it has now stalled, and the top chipmakers are getting frustrated.

        The bill would open up $52 billion in funding to bolster the chip manufacturing, supply chain, and research and development infrastructure in the United States. The bill was introduced in response to chip shortages, with some car makers shutting down assembly plants due lack of components or halting production of specific models.

      • Useful web hosting tips that can help secure your site

        Website security is about preparing for the worst if applied security mechanisms fail. After all, protecting your site from every threat on the book can be laborious. However, it does not mean website owners should not try. It simply refers to the two sides of the coin: preventing attacks or other interruptions and mitigating successful ones.

        Thus, it might be an excellent idea to review the security of your business website to ensure you don’t end up a victim of vicious attacks. Considering that, here are the top 7 definitive web hosting tips to help secure your site for the foreseeable future.

      • Linux Foundation’s Site/BlogLearn the Principles of DevSecOps in New, Free Training Course [Ed: This is what Zemlin et al are 'teaching']

        At the most basic level, there is nothing separating DevSecOps from the DevOps model. However, security, and a culture designed to put security at the forefront has often been an afterthought for many organizations. But in a modern world, as costs and concerns mount from increased security attacks, it must become more prominent. It is possible to provide continuous delivery, in a secure fashion. In fact, CD enhances the security profile. Getting there takes a dedication to people, culture, process, and lastly technology, breaking down silos and unifying multi-disciplinary skill sets. Organizations can optimize and align their value streams towards continuous improvement across the entire organization.

      • USCERTKeeping PowerShell: Measures to Use and Embrace [Ed: Has CISA become a "damage control" or PR department of Microsoft?]

        Cybersecurity authorities from the United States, New Zealand, and the United Kingdom have released a joint Cybersecurity Information Sheet (CIS) on PowerShell. The CIS provides recommendations for proper configuration and monitoring of PowerShell, as opposed to removing or disabling it entirely due to its use by malicious actors after gaining access into victim networks. These recommendations will help defenders detect and prevent abuse by malicious cyber actors, while enabling legitimate use by administrators and defenders.

      • The Register UKFor a few days earlier this year, rogue GitHub apps could have hijacked countless repos

        A GitHub bug could have been exploited earlier this year by connected third-party apps to hijack victims’ source-code repositories.

        For almost a week in late February and early March, rogue applications could have generated scoped installation tokens with elevated permissions, allowing them to gain otherwise unauthorized write or administrative access to developers’ repos. For example, if an app was granted read-only access to an organization or individual’s code repo, the app could effortlessly escalate that to read-write access.

        This security blunder has since been addressed and before any miscreants abused the flaw to, for instance, alter code and steal secrets and credentials, according to Microsoft’s GitHub, which assured The Register it’s “committed to investigating reported security issues.”

        This is good news, because according to Aqua Security researchers, exploitation would have had a massive impact on “basically everyone.” In effect, this is a near hit for the industry as miscreants could have exploited the hole to exfiltrate cloud credentials from private repos or potentially tamper with software projects.

          The European Court of Justice ruled on Tuesday (21 June) that the EU’s Passenger Name Record (PNR) directive must be curtailed to be compatible with fundamental rights.

          The PNR directive was adopted in 2016, introducing a mechanism whereby airlines had to hand to national authorities the data of all the passengers that enter or exit the European Union with the aim of preventing, detecting or investigating terrorist activities and serious crimes.

          The directive allows member states to extend the same screening procedures also to flights from other EU countries, provided that they inform the European Commission. All EU countries except Austria and Ireland notified the Commission of their intention to do that.

          In Belgium, the transposition of the directive into national law was contested by the Ligue des droits humains, which filed an action for annulment before the Belgian Constitutional Court in July 2017. The NGO accused the legislation of introducing generalised surveillance that infringes on the fundamental rights to privacy and data protection.

      • The Coming Recession and Twitch

        With all of this inflation that the world has been seeing the last while, it has resulted in various central banks tightening policy in order to stamp it out. The Federal Reserve in America appears to be getting particularly aggressive with this. Now economists are predicting a recession is likely on the horizon as a result of all this. The Fed seems willing to go to great lengths to create demand destruction and stamp out inflation. This got me wondering about just how the Web will weather such a recession. Looking back on history, such economic downturns have not been kind to the Web. The fallout of the Dot Com crash was very painful. What happened in the wake of the 2008 recession saw a pretty big changing of the guard in terms of what the dominant sites on the Web were. Even smaller events like the “Ad-pocolypse” on YouTube caused significant pain for people who post videos there. Now we’re back to a possible large scale, system-wide economic slowdown, and it’s not hard to imagine that the Web will be in for quite the enema.

        This brings me to how Twitch in particular will or won’t get by. Over the last year or so, it has become obvious that their corporate overlords at Amazon want Twitch to get serious about making a profit.

    Next week the overseeing body of the EPO has a chance to prove it’s no longer subservient to the people it was supposed to regulate and control; it’s all backwards at the EPO, so crime is encouraged (for profit) and never punished for

  25. EPO Abolishing Workers' Rights and Creating Second-Class Workers in Direct Violation of the European Patent Convention (EPC)

    The EPO‘s presidents Benoît Battistelli and António Campinos have demolished any remnant of EPC compliance; this institution must be reobooted immediately and all the managers sacked if not prosecuted



  26. [Meme] Trying to Circumvent the European Patent Convention is Like Playing With Fire

    The EPO‘s repeated violations of the European Patent Convention (EPC) will make António Campinos an asylum seeker like his father, seeking political shelter like Benoît Battistelli, who virtually went into hiding in 2018 (when his diplomatic immunity ended and his EPO crimes, like the Benalla affair, came to light)



  27. EPO Management Severely Harms the Health of Staff by Bullying Them

    EPO management that breaks the law wants the staff to blindly cooperate; failing to achieve full cooperation (in crimes), the managers are increasingly bullying the workers, causing some of them to get ill (in the past this led to a lot of suicides)



  28. [Meme] Executing the EPC (as in Killing It, Not Following It)

    Vichy Battistelli and his French friend have basically killed the EPC, i.e. they committed crimes to turn the EPO into a private bank instead of a patent office; who will hold them accountable and when?



  29. At the EPO, “Bringing Teams Together” or “New Management of Office Space” is Another Step Towards EPO Outsourcing

    The Local Staff Committee Munich (LSC Munich/LSCMN) and Central Staff Committee (CSC) raise awareness of a scheme that may result in only “33% of staff (at best) [having] a permanently allocated desk.” Shades of what the Office dictator Benoît Battistelli did to Judge Corcoran after he repeatedly won in court and his reinstatement was forced, whereupon he found himself back but without a desk



  30. [Meme] Battistelli the Second (Battistelli II)

    Benoît Battistelli‘s French buddy António Campinos is destroying what’s left of the EPO; as the 50th anniversary approaches it’s not clear if the EPO has any future at all (laws aren’t obeyed and new hires aren’t examiners but a disposable workforce, akin to scabs, that doesn’t meet the requirements explicitly specified in the EPC)
