      • Linux MagazineSpiralLinux is a New Linux Distribution Focused on Simplicity

        A new Linux distribution, from the creator of GeckoLinux, is a Debian-based operating system with a focus on simplicity and ease of use.

        SpiralLinux is Debian-based Linux distribution with spins for Cinnamon, XFCE, GNOME, KDE Plasma, Mate, Budgie, LXQt, and Builder (which uses the IceWM window manager for experienced users to fully configure the system to meet their needs). Each of these spins (minus “Builder”) offers a simplified Linux experience that uses the official Debian Stable package repositories.

        SpiralLinux includes Flatpak support built-in as well as a GUI front-end for managing Flatpak packages. The distribution uses the Btrfs file system which includes an optimal subpartition with Zstd transparent compression and built-in support for automatic Snapper snapshots and even zRAM swap support.

        According to the developer, “Great effort has been expended in polishing the SpiralLinux default configuration for all the major desktop environments using the packages and mechanisms that Debian itself provides,” said the dev when asked “why another Debian-based distro.”

      • Status update, June 2022 €· emersion

        Yesterday I’ve finally finished up and merged push notification support for the soju IRC bouncer and the goguma Android client! Highlights & PM notifications should now be delivered much more quickly, and power consumption should go down. Additionally, the IRC extension isn’t tied to a proprietary platform (like Google or Apple) and the push notification payloads are end-to-end encrypted. If you want to read more about the technical details, have a look at the IRCv3 draft.

        In the Wayland world, we’re working hard to get ready for the next wlroots release. We’ve merged numerous improvements for the scene-graph API, xdg-shell v3 and v4 support has been added (to allow xdg-popups to change their position), and a ton of other miscellaneous patches have been merged. Special thanks to Kirill Primak, Alexander Orzechowski and Isaac Freund!

        I’ve also been working on various Wayland protocol bits. The single-pixel-buffer extension allows clients to easily create buffers with a single color instead of having to go through wl_shm. The security-context extension will make it possible for compositors to reliably detect sandboxed clients and apply special policies accordingly (e.g. limit access to screen capture protocols). Thanks for xdg-shell capabilities clients will be able to hide their maximize/minimize/fullscreen buttons when these actions are not supported by the compositor. Xaver Hugl’s content-type extension will enable rules based on the type of the content being displayed (e.g. enable adaptive sync when a game is displayed, or make all video player windows float). Last, I’ve been working on some smaller changes to the core protocol: a new wl_surface.configure event to atomically apply a surface configuration, and a new wl_surface.buffer_scale event to make the compositor send the preferred scale factor instead of letting the clients pick it.

      • UbuntuMaster IoT software updates with validation sets on Ubuntu Core 22 | Ubuntu

        If you are packaging your IoT applications as snaps or containers, you are aware of the benefits of bundling an application with its dependencies. Publishing snaps across different operating system versions and even distributions is much easier than maintaining package dependencies. Automated IoT software updates make managing fleets of devices more efficient. While you can avoid the dependency hell between software packages, how could you ensure that the diverse applications on an IoT device work well together?

        Ubuntu Core 22 introduces the feature of validation sets that makes IoT device management easier. A validation set is a secure policy (assertion) that is signed by your brand and distributed by your dedicated Snap Store. With validation sets you can specify which snaps are required, permitted or forbidden to be installed together on a device. Optionally, specific snap revisions can be set too.

      • Venture BeatUbuntu Core 22 brings real-time Linux options to IoT | VentureBeat

        Embedded and internet of things (IoT) devices are a growing category of computing, and with that growth has come expanded needs for security and manageability.

        One way to help secure embedded and IoT deployments is with a secured operating system, such as Canonical’s Ubuntu Core. The Ubuntu Core provides an optimized version of the open-source Ubuntu Linux operating system for smaller device footprints, using an approach that puts applications into containers. On June 15, Ubuntu Core 22 became generally available, providing users with new capabilities to help accelerate performance and lock down security.

        Ubuntu Core 22 is based on the Ubuntu 22.04 Linux operating system, which is Canonical’s flagship Linux distribution that’s made available for cloud, server and desktop users. Rather than being a general purpose OS, Ubuntu Core makes use of the open-source Snap container technology that was originally developed by Canonical to run applications. With Snaps, an organization can configure which applications should run in a specific IoT or embedded device and lock down the applications for security. Snaps provide a cryptographically authenticated approach for application updates.

    • Computer WeeklyThe challenge of open source in the enterprise is not technical

      There is no doubt that open source is the future of software development. But IT leaders trying to instil an open source culture in their organisation may struggle due to business practices established years earlier to support commercial software contracts.

      Computer Weekly recently had a chat with Amanda Brock, the CEO of OpenUK about how enterprise software contracts have evolved with the advent of open source.

      [...]

      Brock points out that in itself, open source is not a business model. Managed services provides a commercial wrapper. But commercial open source companies are increasingly looking at SaaS as the direction they will take their enterprise software products.

      • Drew DeVaultStatus update, June 2022

        Hello again! I would like to open this post by acknowledging the response to my earlier post, “bleh”. Since it was published, I have received several hundred emails expressing support and kindness. I initially tried to provide these with thoughtful replies, then shorter replies, then I had to stop replying at all, but I did read every one. Thank you, everyone, for sending these. I appreciate it very much, and it means a lot to me.

        I have actually had a lot more fun programming this month than usual, since I decided to spend more time on experimental and interesting projects and less time on routine maintenance or long-term developments. So, the feature you’ve been waiting for in SourceHut might be delayed, but in return, there’s cool progress on the projects that you didn’t even know you were waiting for. Of course, the SourceHut workload never dips below a dull roar, as I have to attend to business matters and customer support promptly, and keep a handle on the patch queue, and the other SourceHut staff and contributors are always hard at work — so there’ll be plenty to discuss in the “what’s cooking” later.

      • defragmentation -- wingolog

        Good morning, hackers! Been a while. It used to be that I had long blocks of uninterrupted time to think and work on projects. Now I have two kids; the longest such time-blocks are on trains (too infrequent, but it happens) and in a less effective but more frequent fashion, after the kids are sleeping. As I start writing this, I'm in an airport waiting for a delayed flight -- my first since the pandemic -- so we can consider this to be the former case.

        It is perhaps out of mechanical sympathy that I have been using my reclaimed time to noodle on a garbage collector. Managing space and managing time have similar concerns: how to do much with little, efficiently packing different-sized allocations into a finite resource.

        I have been itching to write a GC for years, but the proximate event that pushed me over the edge was reading about the Immix collection algorithm a few months ago.

        [...]

        On the engineering side, there's quite a number of choices to make there too: probably you make some parts of your collector to be parallel, maybe the collector and the mutator (the user program) can run concurrently, and so on. Things get complicated, but the fundamental algorithms are relatively simple, and present interesting fundamental tradeoffs.

          Although Python celebrated its 30th birthday last year (2021), it has only recently experienced the rapid acceptance, growth, and upgraded development that we’ve come to identify with the language. Many aspects of Python have remained constant since its beginnings, but with each passing year and each Python edition, new ways have come for accomplishing things and new libraries have been introduced to take advantage of those advancements emerge.

          Python has both ancient and new ways of doing things. It is all about how you understand this language and what scopes you find in it. Actually, Python app development is the most trending language nowadays as developers are finding it more suitable for their projects.

        • How To Convert A String To Int In Python

          Python comes equipped with a variety of data types, each of which may be used to differentiate a certain kind of data. For instance, strings in Python are used to represent data that is based on text, while integers are utilized to represent entire numbers. Converting values from one data type to another allows you to interact with the data in a variety of different ways, which may be useful while you’re doing programming.

          The process of converting a Python string into an integer is a frequent activity. The int() and str() built-in methods are included in Python and may be used to make the aforementioned conversions ().

          In this we will investigate the Python int() function, which may be used to transform a text into an integer.

    • TediumThe Immigration Challenges Professional Athletes Face

      I have a sort of weird relationship with borders because I’m kind of a weird dude. As a self-anointed geography geek, I like borders because there’s not a whole lot of geography without them. And while the history behind any given border is often fascinating, I find them as a whole slightly vexing. That any imaginary line can restrict the movement of people, and often nature, is annoying if practically understandable. With borders comes customs and immigration protocols that hamper, delay, or outright deny people the opportunity to pursue their dreams and ambitions. For those with a limited window to take advantage of their skills, like professional athletes, these restrictions can be more than frustrating. They are often downright devastating. Today’s Tedium is looking at the immigration issues facing professional athletes and what this reveals about immigration in the 21st century.

      • Facing a deluge of bot attacks and takedowns, Iranian feminists and political protesters say Instagram is silencing them - Coda Story

        About a month ago, the UK-based Iranian women’s rights activist Samaneh Savadi published a post on her popular Instagram account about paternal postpartum depression. Shortly after, she noticed an uptick in follow requests.

        At first, Savadi, who regularly publishes feminist and gender-related content on her account, was pleased. But then, she took a closer look at the recently added accounts. Many of them looked like bots: they had pseudonyms, newly created Instagram pages, no posts. Soon, the requests started overwhelming her page — up to 100 a minute.

        “It was never-ending,” Savadi recalled. She briefly switched her page to private, but she didn’t want this deluge of suspicious new followers to keep her from speaking out. Soon, she made her page public again and was quickly inundated with harassing messages and follow requests.

        It wasn’t just Savadi’s page that saw strange activity. Other Iranian feminist-focused accounts soon started reporting the same pattern of events — a surge in follow requests and messages – beginning at roughly the same time in mid-May.

        • Public Domain Review*Unai no tomo*: Catalogues of Japanese Toys (1891–1923) – The Public Domain Review

          When Brooklyn Museum Curator of Ethnology Stewart Culin visited Japan for the first time in the fall of 1909, he escaped from the harangues of curio dealers by asking them to bring him a traditional children’s toy called burri-burri. Culin knew this rare and obscure object only from a specimen in Tokyo’s Imperial Museum and another owned by the collector Seifu Shimizu. Culin’s request to the dealers quickly confirmed the toy’s rarity, as neither he nor any of his numerous assistants were ever offered one. In the end, Culin asked Shimizu to make him a copy to bring back to Brooklyn.

          Only on a subsequent trip to Japan in 1912 did Culin secure an original, from an old shop on Kyoto’s famed Shijo Street. It bore the dim painted traces of pines and storks beneath its patinaed surface, complete with a plaited cord of knotted and tasseled red silk, and was accompanied by a pair of small wooden disks. The only lore that the shop owner could provide Culin was that the burri-burri had been used in an ancient game. The designs seemed to resemble the emblem associated with the Boys Festival, and also with traditional New Year’s toys — battledores and shuttlecocks.
