      • Linbit pushes DRDB-based software as SAN replacement - Blocks and Files

        Savvy Linux users can provide SAN services to physical, virtual and containerized applications without buying a SAN product, by using LinBit open-source software based on DRDB, which is included in the Linux distribution.

        LINBIT provides support for DRBD in a similar way to how Red Hat supports its Linux distro and has four downloadable products on its website: a DRBD Linux kernel driver, DRDB Windows driver, LINSTOR cluster-wide volume manager and, in tech preview form, LINBIT VSAN for VMware. The core product is DRDB, a Distributed Replicated Block Device for Linux.

        An updated version of open source graphics app Pinta is available to download.

        Pinta 2.1 arrives roughly a year after the debut of the Pinta 2.0 series and sees the app upgraded to leverage .NET 7. Building against .NET 6 (LTS) is still supported, the devs say. Talking of .Net (meek link) did you know that the design and feature set of Pinta was inspired by the Windows programme Paint.NET?

        So what’s new in Pinta 2.1?

      • TecAdminDocker system prune: A Detailed Guide to Remove Unused Objects

        Docker is a popular containerization platform that allows you to package, deploy, and run applications in a container. As you use Docker, you may accumulate a large number of images, containers, and volumes that take up space on your system. The `docker system prune` command allows you to remove unused data from your Docker system, including stopped containers, dangling images, and unused networks and volumes.

        In a production environment, it is important to carefully consider the implications of using the `docker system prune`, as it can potentially remove data that is still in use. In this article, we will go over considerations for using docker system prune in a production environment.

        A high-availability cluster is a type of computing system that is designed to ensure that critical services and applications remain available to users with minimal downtime. It consists of multiple servers, or nodes, that are configured to work together to provide a single, unified service or application. If one node fails, the other nodes take over to ensure that the service or application remains available to users.

      • Game RantValve Wants to Bring HDR to Linux Systems

        Valve's programmers successfully implement a development-level iteration of HDR for Linux, marking a major new milestone for the technology.

        Valve's leading coder announces that a proper HDR implementation for Linux is now apparently being developed. It's hardly a secret that the company behind Steam and classic PC games such as Half-Life and Counter-Strike is banking heavily on being able to prop up Linux as a viable alternative to Windows for gamers, and access to cutting-edge features such as High Dynamic Range will help in this regard.

        Following the successful launch of its Steam Deck handheld gaming PC, Valve has doubled down on the importance of Linux for gaming. Its own version of the operating system, SteamOS, is due to release as a free downloadable installation that will be able to run on virtually any modern PC, and support for features that might not be natively present on the Deck is important too.

        Have just released version 4.5.4 and already discovered a bug!

        This bug was introduced with version 4.5, when running in RAM, requiring "save" of session. If you go to the "Shutdown" menu and choose to rollback to a pristine first-bootup, the session is not saved. Unfortunately, there is a file /.rollback.flg that is also not saved, and this file is required by the 'init' script in the initrd, to detect that a rollback is required.

        When to expect these?: As the development of Fedora 38 picks up over the coming months, you can expect the spins to appear during April 2023. Of course, there will be separate ISO files with Budgie and Sway pre-installed.

        So, I think it would be fascinating to see the experience of Budgie with Fedora, especially when the development of Budgie seems to be going through some interesting changes.

        The Raspberry Pi Pico W board was launched with a WiFi 4 and Bluetooth 5.2 LE module based on the Infineon CYW43439 wireless chip in June 2022, and I wrote a tutorial showing how to connect to WiFi a few days after the launch, but nothing about Bluetooth LE.

        That’s because while the Raspberry Pi Pico W hardware supports Bluetooth LE, we were told that Bluetooth was not enabled at the time, but might be at a later stage. The good news comes from Alasdair Allan, who is responsible for the Raspberry Pi documentation, saying Bluetooth LE support is scheduled for the upcoming 1.5.0 release of the Pico C SDK.

        I particularly liked how mapping the set of constraints added during site generation has helped breaking down processing into a series of well defined steps. Code that handles each step now has a specific task, and can rely on clear assumptions.

          The shell is a program that takes commands from the keyboard and gives them to the operating system to perform. This environment lets users run commands, programs, and shell scripts. The shell is both an interactive command language and a scripting language, and is used by the operating system to control the execution of the system using shell scripts.

          The first Unix shell was the Thompson shell, sh, written by Ken Thompson at Bell Labs back in the early 1970s. Nowadays, on many Linux systems, bash (which stands for Bourne Again SHell) acts as the shell program. But there are lots of other free and open source shells available for Linux.

          Zsh is an extremely popular shell. Many of the useful features of bash, ksh, and tcsh were incorporated into zsh. And lots of original features were added.

          Oh My Zsh is a configuration framework to help you manage your Zsh configuration. It’s free and open source software.

    • Tedium10 Blogging Pioneers: Influential, But Not Always Famous

      I think the thing I’ve realized recently is that it’s been so long since we’ve had a fully open online culture that we haven’t really talked about how that is different from what came before, and why it’s something people might want. The reaction when the fediverse, particularly Mastodon, saw a surge in attention was telling. It’s not just the commentary about the platform being confusing or the concern that having to make choices about your digital identity was hard. We have been centralized so long that many of us don’t even remember how it feels to experience online creation on an open plot of land. So with that in mind, given the fresh attention being given to blogging at the moment, I wanted to offer a quick guide to some key early voices in blogging that might give you an idea of what exactly you’re getting into if you decide to start a blog in 2023. This is going to be a listicle style, and I’m going to focus more on historic relevance than fame or authority. For at least some of these, I am specifically highlighting voices you may or may not know so that you dive in a little further. (Folks like Anil Dash and Jason Kottke and John Gruber are hopefully obvious.) The numbers mean nothing in terms of order, other than a rough chronological order. So, with that in mind, today’s Tedium talks blogging pioneers.

        • Bruce SchneierDecarbonizing Cryptocurrencies through Taxation - Schneier on Security

          Maintaining bitcoin and other cryptocurrencies causes about 0.3 percent of global CO2 emissions. That may not sound like a lot, but it’s more than the emissions of Switzerland, Croatia, and Norway combined. As many cryptocurrencies crash and the FTX bankruptcy moves into the litigation stage, regulators are likely to scrutinize the cryptocurrency world more than ever before. This presents a perfect opportunity to curb their environmental damage.

          The good news is that cryptocurrencies don’t have to be carbon intensive. In fact, some have near-zero emissions. To encourage polluting currencies to reduce their carbon footprint, we need to force buyers to pay for their environmental harms through taxes.

          The difference in emissions among cryptocurrencies comes down to how they create new coins. Bitcoin and other high emitters use a system called “proof of work“: to generate coins, participants, or “miners,” have to solve math problems that demand extraordinary computing power. This allows currencies to maintain their decentralized ledger—the blockchain—but requires enormous amounts of energy.

      • No faith in people

        I'm writing this one for myself. I suspect you're better off not reading it.

        I wish I wasn't writing it.

        My mind keeps returning to this essay I read by Maggie Appleton, about AI and the Dark Forest. Her point is that we are going to be inundated by machine written text. It will be harder and harder to spot actual humans. The Dark Forest is basically the fact that the public Internet is full of ghosts, not people. Bots whispering the words they learned from the dead. Underground, hidden, in secret networks, is the smol net, where small circles of humans meet and bond.

        [...]

        I don't pick up calls from unknown numbers. I look them up online, to see if they're spam.

        The bots have poisoned the well. We tried to flee to Instant Messengers, to WhatsApp and Facebook Messenger, until some of us started realising that they kept feeding the vampires out there in the Dark Forest. It gave them info. It taught them how to press our buttons. How to make us angry and keep us from peace. Like Darth Vader, they even benefit from the hate. It fans their fire, balloons their stock options, convinces their customers. The Adverse grows, no matter where you look because it's tracking what you're looking at. And so we use ever more obscure Instant Messengers, fragment into smaller and smaller circles.
