    Open Forms is now 0.4.0 - and the GUI Builder is here

    A quick recap for the newcomers

    Ever been to a conference where you set up a booth or tried to collect quick feedback and experienced the joy of:

    • Captive portal logout
    • Timeouts
    • Flaky Wi-Fi drivers on Linux devices
    • Poor bandwidth or dead zones

    Meme showcasing wifi fails when using forms

    This is exactly what happened while setting up a booth at GUADEC. The Wi-Fi on the Linux tablet worked, we logged into the captive portal, the chip failed, Wi-Fi gone. Restart. Repeat.

    Meme showing a person giving their child a book on 'Wifi drivers on linux' as something to cry about

    We eventually worked around it with a phone hotspot, but that locked the phone to the booth. A one-off inconvenience? Maybe. But at any conference, summit, or community event, at least one of these happens reliably.

    So I looked for a native, offline form collection tool. Nothing existed without a web dependency. So I built one.

    Open Forms is a native GNOME app that collects form inputs locally, stores responses in CSV, works completely offline, and never touches an external service. Your data stays on your device. Full stop.

    What's new in 0.4.0 - the GUI Form Builder

    The original version shipped with one acknowledged limitation: you had to write JSON configs by hand to define your forms.

    Now, I know what you're thinking. "Writing JSON to set up a form? That's totally normal and not at all a terrible first impression for non-technical users." And you'd be completely wrong, to me it was normal and then my sis had this to say "who even thought JSON for such a basic thing is a good idea, who'd even write one" which was true. I knew it and hence it was always on the roadmap to fix, which 0.4.0 finally fixes.

    Open Forms now ships a full visual form builder.

    Design a form entirely from the UI - add fields, set labels, reorder things, tweak options, and hit Save. That's it. The builder writes a standard JSON config to disk, same schema as always, so nothing downstream changes.

    It also works as an editor. Open an existing config, click Edit, and the whole form loads up ready to tweak. Save goes back to the original file. No more JSON editing required.

    Open forms builder page

    Libadwaita is genuinely great

    The builder needed to work well on both a regular desktop and a Linux phone without me maintaining two separate layouts or sprinkling breakpoints everywhere. Libadwaita just... handles that.

    The result is that Open Forms feels native on GNOME and equally at home on a Linux phone, and I genuinely didn't have to think hard about either. That's the kind of toolkit win that's hard to overstate when you're building something solo over weekends.


    The JSON schema is unchanged

    If you already have configs, they work exactly as before. The builder is purely additive, it reads and writes the same format. If you like editing JSON directly, nothing stops you. I'm not going to judge, but my sister might.

    Also thanks to Felipe and all others who gave great ideas about increasing maintainability. JSON might become a technical debt in future, and I appreciate the insights about the same. Let's see how it goes.

    Install

    Snap Store

    snap install open-forms
    

    Flatpak / Build from source

    See the GitHub repository for build instructions. There is also a Flatpak release available .

    What's next

    • A11y improvements
    • Maybe and just maybe an optional sync feature
    • Hosting on Flathub - if you've been through that process and have advice, please reach out

    Open Forms is still a small, focused project doing one thing. If you've ever dealt with Wi-Fi pain while collecting data at an event, give it a try. Bug reports, feature requests, and feedback are all very welcome.

    And if you find it useful - a star on GitHub goes a long way for a solo project. 🙂

      Ivan Molodetskikh: Using Fedora Silverblue for Compositor Development

      news.movim.eu / PlanetGnome • 12:37 • 20 minutes

    I’ve been using Fedora Silverblue on my desktop and laptop for the past, what, five years? Silverblue is Fedora’s main atomic variant, a spiritual counterpart to Fedora Workstation. I also make niri , a scrollable-tiling Wayland compositor. In other words, a core system component that you cannot properly test from inside a container or VM—you really want it directly on the host. So, why would I choose an… immutable distro? How does that even work?

    blur.png

    Fedora Silverblue makes a frequent occurrence in my niri release notes screenshots.

    Atomic distributions have been slowly rising in popularity. Their main selling point is reliability: upgrades work by swapping the old system for the new one in one go across a reboot, rather than modifying the files in-place. Package conflicts and other errors are caught at the time of assembling the new version (in a separate folder), and therefore cannot break your running system. And if a successful update turns out buggy, atomic distros let you simply reboot back into the old version and keep using it as if nothing happened.

    This “being able to reboot back” thing becomes even cooler once you realize that it works even across major distro upgrades! When the next Fedora Beta rolls around, I can just rebase my system on top of it to kick the tires, and if anything is broken, I can simply reboot back to stable Fedora (and then undo the rebase).

    This is like learning about source code version control. A big weight off your mind any time you want to mess around with your OS. You can just go back .

    So, by now there are plenty of atomic distributions to choose from. There’s a whole host of Fedora atomic desktops , Endless OS , the gaming-focused Bazzite and other Universal Blue images . GNOME OS Nightly is atomic, as well as SteamOS powering the Steam Deck. Many of these are built with OSTree which is something of a “git for operating system binaries”.

    But, you may ask. What if I develop these operating system binaries? Aren’t atomic distros immutable and all, how do I test my work?

    Turns out, this is not a problem at all! In fact, the same tech that lets you go back after an update can also let you freely tinker with your host system and safely go back after a reboot. I’d say that thanks to this ability, atomic distributions provide even more benefit for system component developers than for others, given that they’re constantly testing changes that may break their install.

    So, let me show you how I do compositor development on Fedora Silverblue. We’ll start with toolbox where most of the work happens, then proceed to the fun stuff.

    Toolbox #

    On your immutable host system, you need a place where you can install the development environment. Fedora Silverblue comes pre-installed with Toolbox , which provides just that—a terminal in a normal, mutable Fedora where you can sudo dnf install to your heart’s content.

    Under the hood, it’s just a podman container with a whole range of things auto-mounted from the host: the Wayland socket, networking, devices, D-Bus, and everything else needed for apps to “just work” as much as possible from inside the container. You can even interact with it through podman commands:

    ┌ ~
    └─ podman ps
    CONTAINER ID  IMAGE                                         COMMAND               CREATED       STATUS         PORTS       NAMES
    6ceccce5581e  registry.fedoraproject.org/fedora-toolbox:44  toolbox --log-lev...  2 months ago  Up 41 minutes              fedora-toolbox-44
    

    Most of your development work happens here. Install all the libraries, compilers, editors, LSPs , debuggers, and the rest of the kitchen sink. Since all of this resides inside the same container, it can all talk to each other and work together.

    One slightly annoying detail is that since your fully-configured editor is inside the toolbox, you can’t use it to edit files accessible only on the host (e.g. configs in /etc —the system inside the toolbox has its own files there), but that is honestly a fairly minor problem in practice. Fedora Silverblue comes with nano , which works, and if editing host-only files is a frequent occurrence for you, you can always rpm-ostree install a more featureful editor. Another annoying problem is that currently, toolbox prevents SIGHUP from reaching apps , so if you run your favorite editor then close the terminal window, it will happily keep running in the background (along with all its rust-analyzer s and such, eating several gigabytes of RAM).

    So, running things in a toolbox works perfectly well for most development. CLI tools will run fine, GUI apps will run fine, you can build and install libraries inside the toolbox and test them on apps inside the same toolbox. Even with Wayland compositors, most of them can run as a window ( gnome-shell --nested , or simply sway or niri ), which is enough to test the majority of the code base.

    Moreover, since ~2023 , toolbox exposes everything necessary to run compositors on a TTY directly. You can switch to a different VT with Ctrl Alt F3 , toolbox enter , then start a compositor, and it will work as is. This way you can test different input devices directly (trackpad, tablet, touchscreen), test monitor and GPU handling, do proper performance profiling, and so on. Just remember to install a terminal and some GUI apps inside the toolbox because launching the host ones into a toolbox compositor is a bit annoying.

    While toolbox is somewhat Fedora-specific, for everything else there’s distrobox . It’s a separate project, but by and large has the same idea—let you easily install different distros as podman containers with automatic host integration. I mainly use it to build or test things on Arch , but I imagine most of what I wrote above works just as well with distrobox.

    What if this isn’t enough, though? Say, you’re working on a component like NetworkManager or systemd that must run on the host system. Or, you want to be able to log in to a test build of your compositor along with the rest of the full desktop session. Let’s look at an easy way to do that.

    Unlocking the host #

    Run sudo ostree admin unlock , also known as rpm-ostree usroverlay . 1 2 This will mount a mutable overlay filesystem over /usr for you to play around in. The overlay will last until the next reboot, at which point you’ll be back to a clean working system.

    Now you can simply sudo cp your development build into /usr/bin and restart the service you’re testing.

    This also works with libraries. Say, you want to test your changes in GTK against apps installed on the host. 3 Build it inside the toolbox, then copy the binaries to the (unlocked) host, and there you have it. Binary compatibility is generally not a concern since Silverblue updates daily and very closely matches the regular Fedora that you build against inside the toolbox.

    sudo cp is not a proper substitute for installing though, and you cannot use it as easily for many projects. So let’s get some proper tooling on the host.

    Layering development tooling #

    Contrary to an apparently widespread belief, you can install packages on the host in Silverblue. This is called layering and is a perfectly normal and supported operation, primarily useful for adding system components such as terminals, window managers, or GPU drivers. Running rpm-ostree install alacritty will cause rpm-ostree to install, or layer , this package on top of the base Silverblue image every time it updates. After a reboot, you’ll have Fedora with Alacritty , as if you installed it on a regular, non-atomic system.

    If the change is sufficiently non-invasive, running sudo rpm-ostree apply-live lets you skip the reboot and have a newly installed program available right away. 4

    When should you layer (as opposed to installing in a toolbox)? Layering is more annoying and slower, and misses the benefit of throwing away a toolbox to start fresh. So, I limit layering to programs that must run on the host, and tools that I frequently need on the host.

    Here’s my list of layered packages that’s been more or less unchanged for several Fedora releases:

                    Initramfs: --include /etc/initramfs-overlay /
    

    In this output, you can find:

    • I removed Firefox with rpm-ostree override remove —I prefer the official build from Flathub .
    • Terminals (must run on the host to access the full host filesystem 5 ): alacritty, foot, gnome-console. My preferred shell: fish. Tool I frequently need: tmux.
    • Services and tools that I want to run without a toolbox: syncthing, distrobox, netconsole-service, trash-cli, htop, fastfetch, lm_sensors, rocminfo.
    • Desktop components: fuzzel, hyprlock, i3, kanshi, labwc, lxqt-policykit, mako, quickshell-git, sway, waybar, wlsunset.
    • edid-asus and the initramfs-overlay provide the EDID for one of my monitors after AMDGPU broke it back in kernel 4.19. 6

    Along with these, I layer several development tools: gdb, strace, perf, sysprof. These frequently come in handy whenever I need to debug or profile programs running on the host (or do full-system profiling in case of Sysprof ).

    And then there’s dnf. What?

    Layering dnf #

    What is dnf, a regular Fedora package manager, doing on an immutable Silverblue host system? By itself, it’s not very useful indeed, since it can’t modify /usr . (Though, it can dnf copr enable , which is convenient. rpm-ostree copr when?)

    Where dnf on the host shines, however, is when you combine it with sudo ostree admin unlock . After unlocking, you can install whatever you need in the moment with dnf. This is much faster than rpm-ostree, never requires a reboot, and in fact a reboot makes it all clean up and go away, since it was all in a transient /usr overlayfs.

    Example workflows:

    • dnf debuginfo-install to debug/profile something on the host with symbols, report crashes, etc.
    • dnf install some host-only program to test it. Follow up with rpm-ostree install if you decide to keep it.
    • dnf builddep gtk4 , then build and sudo ninja install GTK 4 right on the host to test it against host apps. If anything breaks, just reboot, and you’re back to a clean working state.

    Unlocking + layering dnf is a very powerful development workflow to the point where I’d almost want dnf included in Silverblue by default. Unfortunately, this workflow is also unobvious enough that the dnf maintainers accidentally prevented it from working some time ago (thankfully, quickly corrected). I understand the UX concern about having dnf visibly available when it cannot work outside this specific workflow, but perhaps Silverblue could just hide it somehow unless the host is unlocked, or rename the dnf binary?

    Persistent unlocking #

    Generally to put something persistently on the host, you’d just layer it with rpm-ostree install . However, sometimes what you want is a temporary change that also happens to persist across reboots.

    This sounds weird, but consider testing a kernel build. You want it to be temporary and easy to roll back, but you kinda have to reboot into the new kernel. And you also don’t want to spend extra time building and layering .rpms.

    For this situation, ostree admin unlock comes with a --hotfix flag. It’ll persist the temporary overlay across reboots, and will only reset itself once you explicitly make some change with rpm-ostree . Note that you never lose the ability to reboot into the previous, working system.

    Summing it all up #

    So, this is what my development workflow looks like.

    • Most work happens in one kitchen-sink toolbox that I (like to but am not required to) reinstall every Fedora release to keep cruft from building up. This includes building and running niri on a TTY.
    • After finishing a change, I unlock the host with sudo ostree admin unlock , copy over the niri binary, and re-log in to test it in my real session. This will automatically reset upon a reboot.
    • When working on a long-running branch, I’ll build a work-in-progress niri .rpm and layer it with rpm-ostree install to persist the new version across reboots.
    • I use dnf install on the host when I want to throwaway-test something host-specific and have it automatically reset upon a reboot.

    Over time I made a few small quality-of-life tweaks to smooth out some rough edges in this workflow.

    For example, toolbox enter is a mouthful and always drops me into bash . Enter t , a script in my ~/.local/bin/ , always available in $PATH :

    #!/bin/bash
    
    if [ $# -eq 0 ]; then
        command=fish
    else
        command="$(printf "%q " "$@")"
    fi
    
    exec toolbox run -c fedora-toolbox-44 bash -ic "$command"
    

    Now, typing t puts me in the toolbox directly into my dear fish shell. Typing

    t some-program "with complex" arguments | grep "and stuff"
    

    also works as expected, with correct argument passing thanks to printf "%q " .

    This works for .desktop files too. Say, you installed VSCode in the toolbox and got a .desktop file. Just change:

    Exec=/usr/share/code/code --ozone-platform-hint=auto %F
    

    to:

    Exec=t /usr/share/code/code --ozone-platform-hint=auto %F
    

    and it’ll run in the toolbox. (I understand distrobox handles .desktop files automatically.)

    Note that I use toolbox run but route the command through bash. This is necessary to get all environment variables like $DEBUGINFOD_URLS that distros keep stubbornly putting in /etc/profile.d/ scripts, which of course don’t get sourced without a bash -i .

    Another quality-of-life improvement was binding a separate hotkey to spawning a terminal directly in the toolbox. I actually noticed that most of the time, when I open a terminal, I want to be in the toolbox, so now my Super T spawns the toolbox Alacritty, while the less convenient Super Shift T spawns the host Alacritty.

    Furthermore, at some point I got tired of waiting for the…

    ┌ ~
    └─ hyperfine -w 3 --shell=none 'true' 't true'

    …extra 250 ms for toolbox run , and wrote a script that keeps Alacritty running as a daemon inside (and outside) the toolbox, making opening a new terminal window always instant. As a bonus, this happens to fix the SIGHUP problem that I mentioned above: since Alacritty runs directly inside the toolbox, closing its window will properly close the terminal app running inside.

    (Eventually I went even further and made a tiny service for fun that runs inside the toolbox, listens to a socket, and runs the command it receives. I only use it in .desktop files though instead of t to avoid the 250 ms delay. 7 )

    What about other systems? #

    I quite like my Silverblue setup. It very much works , and with the tools that it has, it lets me do anything that I might need.

    Silverblue is not without its problems however, so I’ve been thinking about what parts of the experience I find important, and how well other distributions currently satisfy them.

    1. The ability to reboot to a previous, working system. Most new atomic/immutable distros can do this since it’s the main value proposition. It’s also possible on NixOS . On traditional distros I think you can get something close with btrfs snapshots, but it requires a complex setup.

    A/B updates tie closely into this, where rather than mutating the running system, an update is prepared in a separate folder, then atomically swapped with the previous system version (which remains available to boot into should something go awry).

    2. Anti-hysteresis. The host system always stays clean, packages don’t build up over time.

    On a normal distro, a few months is enough for you to scarcely have any idea about all the random one-off packages you installed and forgot about, especially various development tooling and build dependencies not to mention the texlive-full installation . They use up disk space and time during system updates, sometimes cause conflicts and other annoying issues. Config migrations build up, and your system gradually drifts away from a clean well-tested upstream state.

    Immutable distros solve this by not letting you install stuff on the host, and every updated rebuild of the host system starts from a fresh state, so there’s no accumulation of junk.

    NixOS and Silverblue do let you add (layer) packages, so they can build up, but:

    • they make it sufficiently annoying, making you prefer non-host environments such as toolbox for one-off packages;
    • even with layered packages, the system is rebuilt from a fresh state every update.

    Technically, you could use toolbox for everything even on a normal Fedora Workstation, but this requires discipline and doesn’t save you from config migrations, SELinux labeling changes, etc.

    3. The ability to easily install things on the host. This is the part where many newer immutable distros fail to provide a good experience. I need to install programs on the host, whether it’s because I want some host desktop components, or to test my own compositor, or whatever.

    Often, I want to install something on the host quickly . For distros such as Universal Blue spins and other bootc -based systems, the suggested way to include components on the host is making your own downstream spin. But this works only for long-term packages: I don’t want to spend time editing and kicking off a full system build just to test some new terminal or notification daemon, not to mention the whole question of how to keep such a custom system always up to date with its base distro.

    Compare this with rpm-ostree install on Silverblue: one command, slow but tolerable, and the OS remains automatically updated with no extra setup.

    Some systems are even more limited, like GNOME OS which is based on the Freedesktop SDK . The selection of tools and libraries available in the Freedesktop SDK is (intentionally) much more limited compared to most distros, so in many cases you’ll find yourself having to go and build whatever you need from source. If that happens to be something big and complex like Qt (to try a hot new Quickshell -based desktop): good luck; I hope you didn’t have plans for the weekend.

    A common suggestion for these OSes is systemd-sysext that lets you build an image and overlay it over /usr. Florian Müllner gave a talk at the 2025 GUADEC showing a nice workflow for using sysexts for Mutter and GNOME Shell development and testing on immutable distros.

    It’s also possible to enforce system version compatibility checks in sysexts. A system like GNOME OS could build and ship a collection of sysexts version-locked to the runtime they were built against, and automatically updated together with the rest of the system using systemd-sysupdate, resulting in an experience similar to layered packages. (In fact, GNOME OS does have that, just the selection of sysexts is fairly small.)

    Some software can be packaged into self-contained sysexts that work on most distros. The Flatcar sysext-bakery is one repository of such sysexts.

    What’s wrong then? Well, the main limitation of sysexts is that they are meant for tools without dependencies. They do not do any dependency resolution or support any dependencies other than, optionally, the base OS itself. Back to my example, while it’s possible to build and ship sysexts for Qt apps that bundle Qt itself, all of those sysexts will carry their own copies of Qt. Even worse, since they are mounted into the same filesystem tree, conflicting files (say, different-version Qt binaries) will get mounted only from one of the sysexts, whichever one happens to mount last. So sysexts aren’t a complete replacement for packages (nor are they intended to be).

    4. The ability to make transient changes to the host. While I don’t immediately see why you couldn’t put a writable overlay on any regular distro like what ostree admin unlock does, I haven’t seen anyone doing it, or any simple “no thinking necessary” tools for it. 1 Perhaps it’s too easy to mess up outside immutable systems?

    It’s worth noting that some paths like /etc aren’t usually covered by immutability and overlays, so you still need to be a bit careful.

    Conclusion #

    All in all, Silverblue appears to be a sweet spot between offering immutable/atomic guarantees with plenty of useful tooling bundled in, while also being a normal Fedora with a wide package selection available for both persistent layering and quick transient installation. I appreciate the QA and other behind-the-scenes work that goes into my ability to install Silverblue and be reasonably sure that it will work, and keep working, with all of my hardware, and that I won’t have to hunt for packages to get a working bluetooth or what have you. My Silverblue installs are the longest I’ve kept any single distro, and I have no urge to reinstall because my host system remains clean and I know exactly what it comprises.

    My issues with Silverblue mostly boil down to some rough edges and slowness of rpm-ostree , and some less than ideal Flatpak repository defaults. Having to do most of the work in a container is somewhat annoying at times, especially when dealing with nested containerization or VMs. But I’m not sure there’s a better way fundamentally, without trading host system robustness. For the few things that do require it, I can always unlock the host.

    I hope this post sheds some light on immutable system workflows and perhaps inspires you to try one. I’d also love to hear your feedback and suggestions! Did I miss something? Is there a better way of doing things? A new system that solves all problems and makes everything better? Please reach out to me on Mastodon or by email, linked at the bottom of the page!


    1. I’m told the modern alternative is systemd-sysext merge --mutable=ephemeral , which works across all distros and not just Silverblue. Haven’t tried it myself yet! ↩︎ ↩︎

    2. I didn’t quite realize this before, but rpm-ostree usroverlay seems to literally exec ostree admin unlock :

      ┌ ~
      └─ rpm-ostree usroverlay -h
      Usage:
        ostree admin unlock [OPTION…]
      
      Make the current deployment mutable (as a hotfix or development)
      (...)
      ┌ ~
      └─ rpm-ostree usroverlay --version
      libostree:
       Version: '2025.4'
       Git: 99a03a7bb8caa774668222a0caace3b7e734042e
      (...)
      
      ↩︎
    3. Which is, uhh, not a lot of apps come to think of it. Nautilus, Ptyxis, Software, System Monitor, Settings, xdg-desktop-portal-gnome dialogs—the rest come as Flatpaks on Silverblue. How to test your GTK changes against those Flatpak apps? Uhhhhhh ↩︎

    4. For years, it’s been rpm-ostree ex apply-live , where ex stood for experimental . I guess I’ve been procrastinating on this blogpost long enough that it had time to graduate to non-experimental rpm-ostree apply-live . ↩︎

    5. The Ptyxis terminal can work properly on the host even when installed as a Flatpak. It does this by spawning a small binary on the host (through a host-run permission) that does all command spawning and PTY communication, while the Ptyxis GUI remains inside Flatpak. This is a clever workaround, but requires a sandbox hole and very careful engineering, and arguably runs somewhat at odds with the point of Flatpak. ↩︎

    6. Since writing that example, I replaced that monitor and finally got rid of the custom initramfs. This is faster because without overrides, Silverblue directly uses an initramfs built on Fedora servers, and I think it also works better with secure boot? Either way, I wanted to leave it in as an example that you can customize the initramfs on Silverblue if needed. ↩︎

      Daniel García Moreno: Take it easy. A guide to avoid burnown during the Vulnpocalypse

      news.movim.eu / PlanetGnome • 10:00 • 7 minutes

    Do not let the AI to remove the fun part from software development. We shouldn't allow gen AI to write software just because it "can". First, we must ask if it "should" do it, and even then, we should ask if we want to delegate the fun part, the thinking, the writing, the learning.

    Remember what's important, journey before destination, we are the Code :

    Do not let AI to destroy the community, do not let it destroy the technological knowledge commons .

    tl;dr

    Open Source maintainers are dealing with a lot of new reports and pressure to "fix" the project due to generative AI.

    We need to find a way of stopping this and get back to something maintainable before all maintainers get burned out and look for a job in a farm:

    • 100% secure software doesn't exists, so there will be always a possible CVE there. As Spaf said in 1989 :

    The only truly secure system is one that is powered off, cast in a block of concrete and sealed in a lead-lined room with armed guards - and even then I have my doubts.

    • Fixing bugs, adds new bugs, and if you need to fix something quick, the probability of new bugs will be higher. Do not forget about the First Law of Programming:

    If it works, don't touch it

    • The amount of CVE reports is lowering the CVE credibility and quality, so if everything is a "high" security issue, we can't prioritize now and these reports are not different from random issues in github. Do not listen to The Boy Who Cried Wolf

    • Stable software is sable because it doesn't change too much. It's something that we are willing to loose trying to reach the impossible of 100% secure software?

    The actual problem

    There's a lot of money in AI tech right now, and everyone is trying to make the best gen AI tool or just pretend that their tool is the best.

    In relation with the software analysis and writing, targeting the open source is the obvious strategy.

    1. It's interesting to scrap every line of code, patch, pull request, issue and discussion around software to train your model, so AI scrappers are DDoSing open source projects infrastructure.

    2. To promote their tools or themselves, Security Researches are using AI to target any project, reporting High security vulnerabilities , with the only goal of getting a CVE number to say how good they are.

    This second point is affecting maintainers, because now you are receiving a lot of poor quality security reports, that are generated with AI and that looks plausible and are hard to read. You need to spend a lot of time to check if there's an actual wolf there or if it's again this boy that's tricking me.

    This is burning the energy of maintainers, that instead of doing something productive are wasting their limited time talking with a Stocatic Parrot .

    Do not let the AI Bros to use classic manipulation techniques on you!

    A lot of open source projects are maintained by volunteers that do the work with passion and love. And even if it's the job that paid your bills, the maintainer can feel the pressure . When someone put a lot of love in something and work on it during years, it's part of his identity, so attacking the software is like attacking the person behind it.

    This is nothing new, and a lot of people take advantage of this emotional link to manipulate the maintainer to do something that he do not want to do.

    AI bros are using these techniques, do not let them to manipulate you and define your project agenda.

    Here's a (not complete) list of known manipulation techniques that you can detect (and disarm!) in your daily community work:

    • Flooding the queue . Just create so many new issues that the actual maintainers can't deal with it. You feel responsible for the project and feel bad because your TO-DO list is growing.

    • This software is not secure (doesn't do what I want), I will use this other one instead that's better . The classic, "GNOME doesn't allow me to change this specific preference, I'll use KDE from now on".

    • This software is low quality, it doesn't follow the (my random) quality standards . Direct attack to the maintainer self-esteem.

    • Gaslighting software development . LLM are expert at this and people that uses it just copy the tactic. When the maintainer detects something weird and just tries to blame the other person for reporting nonsense and wasting all people time, it starts to invent new arguments and ignore the previous interaction.

    So, take it easy, and remember the best clause in almost any software project, THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU :

    Disclaimer of Warranty.
    
    THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
    APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
    HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM AS IS WITHOUT
    WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT
    LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR
    A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
    PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE
    DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
    CORRECTION.
    

    Is the software more insecure in 2026?

    No. Anyone old enough could remember how insecure old software was. Do you remember windows 98? Do you remember the internet when everything was http (without that little s at the end), when people use ftp to logging into their server and modify the php code directly on production?

    It's true that today we have more dependency on technology, but it's also true that everything is more secure, we have more and better cryptography, we have different levels of isolation, virtual environments, containers, virtual machines...

    But we have the feeling that since AI can analyse all the software and look for vulnerabilities, we are doomed, because any stupid kid can hack my over engineered GNU/Linux machine!

    First, that's not true, you need to know about security to get something useful from any AI tool. But even if it was true, what can you do about it? We need to be practical and find a balance between risk and usefulness, so do not overestimate the risk just because everyone is talking about it right now.

    But even then, the security paranoia is not good for anyone. Software is inherently buggy, people write software and makes mistakes, so a possible vulnerability appears. In theory, these bugs are fixed when discovered, so it's always recommended to update to the latest version, because almost all known bugs will be fixed.

    But it's also known that new versions comes with new functionality and code, and that means new "unknown" bugs or different behavior. That's a headache, so that's why the stable and Long Term Support are popular distributions, because "if it works, don't touch it" .

    Stable packages just get the fixes, not new features, but fixes are also code changes, so there's always a possibility to break something, even with a patch update.

    The stable software has a lot of value, do not let the AI security paranoia destroy that, and convert everything in a rolling release with the latest and greatest (and possibly broken) software. Sometimes it's better to keep using something old, with known vulnerabilities that you can mitigate, than use the latest with unknown new vulnerabilities that you can't do anything about.

    I will fight AI with AI

    Please, do not do that. What I was trying to argue during this long post is not a technical problem. The current burnout problem in open source is a social problem, you can't fix it with a new layer of probabilistic tokens.

    • Community reaction against AI . The current industry push for the usage of AI everywhere is affecting a lot of people, and as a reaction a lot of people are directly fighting back. Using gen AI just sends the message that you do not care enough to do it yourself, and destroy the trust on the project.

    • It doesn't worth it . Even if the AI works (that it doesn't) it doesn't worth it. Writing code is easier than reviewing, you learn and grow with every new line of code that you write, delegating the fun part and personal growth part to an AI will make you work more miserable and you will be a junior forever.

    • It doesn't create community . Think about it, it's hard to get someone involved in a software project, but who will want to read or improve the code produced by a gen AI? The only future collaborator will be another AI.

    Take it easy

    Just remember, you can always say no, there's no hurry, and there's no need to work on something that you don't want just because other people consider that important.

    Free Source is something done by people, for people. The software is important, but the community around it is sometimes more important. We use Free source not because it's technically better (that it is), but because we trust who, how and why are writing it.

    Remember why are you doing this, do not remove the Fun part, continue with the Just for Fun mood.

      Nick Richards: Sunset Appearance

      news.movim.eu / PlanetGnome • 1 day ago • 3 minutes

    I love adaptive interfaces and technology that blends in more than the average human. I’ve spent literally years tinkering with ‘frecency’ ordered lists, bought a meural screen and have recently been glorying in the fantastic GNOME Adaptive Brightness .

    On that last point, whilst GNOME already has Automatic Screen Brightness, and it is a good feature, dmy3k’s extension goes further on the specific machines with cool hardware: steadier behaviour with changing light, smoother transitions and brightness curves you can tune. One of the things I’ve been exploring with extensions recently is ’this feature, only more so’ and adaptive brightness is a good example.

    Living far from the equator, evenings happen. The room goes grey, the window stops being a useful light source and GNOME is still cheerfully in light mode because I told it to be bright at the time one takes screenshots. Night Light is already doing its bit by then. The display has warmed up, which is nice, but the rest of the interface lacks the level of ‘darque’ required. I wanted the normal GNOME appearance preference to follow the day as well: light while it still feels like day, dark once the evening has properly arrived. Users of other operating systems may be aware of this feature, but for the purposes of this blog post let us pretend that everything below is entirely unique.

    So I hacked up Sunset Appearance , a small GNOME Shell extension for GNOME Shell 45 to 50. At civil dusk it writes the same setting GNOME Settings uses:

    org.gnome.desktop.interface color-scheme = 'prefer-dark'
    

    At civil dawn it sets it back to:

    org.gnome.desktop.interface color-scheme = 'default'
    

    My dad was an aviator, so I got to hear a lot of exciting words growing up, such as ‘civil twilight’, which always makes me think of Romeo and Juliet. Sunset turns out to be a surprisingly slippery concept, and very longitudinally mediated. In London in summer there can be plenty of useful light after the sun has dipped below the horizon, and the desktop does not need to go ‘darque’ the moment the sun touches the skyline. Nautical and astronomical twilight are too late for an interface preference, and in some places at some times of year they can fail to happen in the normal way at all.

    Civil twilight is when the centre of the sun is 6 degrees below the horizon and when it really does feel like the world has changed character.

    Location is awkward too, because civil dawn and dusk need latitude, longitude and date. There’s some interesting fallback logic to infrequently get a coarse location (good enough for a city) and then fall back to cached data if available as Night Light already needs much the same information. Frequent readers will remember my concerns over London, Ontario being above London, England in many search boxes so there is no virtue in making the user type London into another small box. If neither source has usable coordinates, nothing changes.

    Manual override behaviour is another thing that avoids annoyance. If the extension sets dark mode at dusk and I then change GNOME back to light mode, I meant that. After any override, it waits until the next scheduled dawn or dusk transition before touching the setting again.

    Solar time code has an unreasonable number of edges for something everyone thinks they intuitively understand. Keeping with my aggressive policy on internationalisation the tests keep London as the ordinary case, then poke at time zones, date line longitudes, DST changes, Antarctic stations, Arctic towns, awkward offsets such as Lord Howe and Chatham and cases where civil dawn or dusk may not exist at all. My time reading brr and pretending to be in New Zealand to solve work bugs was not poorly spent.

    Right now Sunset Appearance can be built from source . At some point I may choose to distribute it more widely, or even see if someone has already solved my problem better.

    Backrooms

    Not the best film ever, but in today's Hollywood landscape it's a rare breath of fresh air. Kane Parsons takes the internet meme concept he started on YouTube and actually makes a feature-length film that's doing great at the box office.

    The mood is great. That unsettling stillness of these generic liminal spaces. For something that builds a feeling / mood, the flick would benefit from a butcher in the editing room. I'd probably still not give it the extra star, but this really isn't the kind of movie that needs the extra 20 minutes.

    Biggest entertainment was definitely watching my son freak out in the third act. :)

      Christian Hergert: Libdex Improvements

      news.movim.eu / PlanetGnome • 3 days ago • 2 minutes

    libdex 1.2 is still in pre-alpha phase but it is also far enough along that it is worth talking about the direction: libdex is growing from a library of future and fiber helpers into a more complete concurrency toolkit.

    The most important 1.2 theme is that applications can now describe not just what work should happen concurrently, but how that work should be bounded and owned. DexLimiter lets a workload run with a fixed concurrency budget, with dex_limiter_run() handling the common fiber case by acquiring a permit before work starts and releasing it after the fiber completes. For larger workflows, DexTaskGroup gives related futures a structured scope that can be closed, awaited, or cancelled as one unit.

    That combination makes cleanup much easier to reason about when a workflow has many moving pieces. A loader can start many subtasks, keep only a useful number active at once, and return a single future representing the whole operation. If the window closes, the project changes, or the operation times out, the group gives the application one place to cleanly shut the work down.

    static DexFuture *
    load_many_files (GPtrArray *files)
    {
      g_autoptr(DexTaskGroup) group = dex_task_group_new (0);
      g_autoptr(DexLimiter) limiter = dex_limiter_new (8);
    
      for (guint i = 0; i < files->len; i++)
        {
          GFile *file = g_ptr_array_index (files, i);
    
          dex_task_group_add (group,
                              dex_limiter_run (limiter,
                                               NULL,
                                               0,
                                               load_one_file,
                                               g_object_ref (file),
                                               g_object_unref));
        }
    
      return dex_future_with_timeout_seconds (dex_task_group_close (group), 10);
    }

    There is also a new DexThreadPool for the cases that are not naturally fiber-shaped. Fibers and schedulers are still the right fit for cooperative async work, but many applications need to integrate blocking libraries, database clients, filesystem helpers, or other foreign code. A fixed pool of reusable OS threads, dex_thread_pool_submit() , and asynchronous dex_thread_pool_close() give that integration story a bounded queue and an explicit shutdown path.

    Deadlines are another practical piece of the same story. The new timeout wrappers, including dex_future_with_timeout_seconds() and dex_future_with_deadline() , turn time limits into ordinary future composition. Instead of open-coded timeout state spread across an application, a future can resolve normally, reject normally, or reject with DEX_ERROR_TIMED_OUT when the deadline wins.

    On the I/O side, 1.2 continues filling in the operations that make responsiveness easier to preserve. dex_aio_open() and dex_aio_close() matter because even operations that look small can stall when they touch the kernel, storage, or network-backed filesystems. Keeping those calls in libdex’s file-descriptor AIO model makes it easier to keep them off the UI thread, using io_uring where it is available and the fallback AIO backend elsewhere.

    The broader GIO coverage is intentionally less surprising, but still important. More app launching, GFile , stream, socket, resolver, proxy, TLS, DTLS, permission, subprocess, and Unix-facing APIs now have future-first wrappers. That is the kind of coverage people should expect from libdex over time: not every wrapper needs a release headline, but each one reduces the pressure to leave the future model for common GNOME application work.

      GNOME Internationalization & Localization: Some news about the internationalization project

      news.movim.eu / PlanetGnome • 3 days ago • 2 minutes

    This first blog post marks the opening of the internationalization blog! The i18n team will use it to share news and projects on the current plans. Don’t forget to subscribe!

    The i18n team has seen some changes recently, at the beginning of 2026 and we thought it was necessary to publicly announce this change and introduce ourselves a bit.

    Before all, we want to greet and deeply thank all internationalization coordinators that participated in the project so far and made GNOME what is is now. We are a global software community of volunteers, leading the free software ecosystem and are accessible in many languages. With this, we cover almost everyone on Earth. Thank you very much Andre, Alexandre, Claude, Daniel, Gábor, Gil, Mario, Piotr, Petr, Kjartan and all the others. Without you this wouldn’t have been possible.

    What is internationalization?

    Internationalization, or i18n for short, is the act of ensuring software or documentation can be used in other languages, countries, and cultures. This means designing and developing applications in a way that removes barriers to localization, making it possible to adapt them without requiring significant engineering changes.

    In practice, this involves separating user-facing text from the source code, so it can be translated easily, and ensuring that the software correctly handles different character sets and writing systems, including right-to-left scripts. It also means being mindful of cultural conventions such as date and time formats, number formatting, currencies, and units of measurement.

    Internationalization goes beyond text. It includes accommodating differences in sorting rules (collation), keyboard input methods, plural forms, and even layout considerations, as translated text can vary significantly in length. Developers must also ensure that their software supports Unicode and uses libraries or frameworks that simplify handling these variations.

    For the GNOME community, internationalization is a collaborative effort between developers, designers, and translators. By preparing software properly, the i18n team enables localization contributors to focus on producing high-quality translations, ensuring that GNOME is accessible and welcoming to users all around the world.

    A new team

    The team has reborn with new faces: Anders Jonsson, Rafael Fontenelle and Guillaume Bernard, respectively coordinators of the Swedish, Brazilian Portuguese and French team. Let’s introduce ourselves a bit…

    Rafael ( @rafaelff ) is coordinator of the GNOME Brazilian Portuguese Team for more than 13 years after a short but intense period of contribution as translator. Besides GNOME, he contributes to the translation of Python Docs, R language, Fedora, TranslationProject (GNU projects, etc.) and others. Also maintains some packages in Arch Linux’s AUR.

    Anders ( @ajonsson ) is coordinator of the GNOME Swedish Team for over 10 years, translator in the Swedish branch of the Translation Project, and a member of the GIMP Team with a focus on internationalization questions and testing.

    Guillaume ( @gbernard ) is coordinator of the GNOME French Team since this year after 14 years of contributions, first as a translator, reviewer and after a few years, he has been involved in submitting team’s translations. He is the maintainer of GNOME Damnes Lies , our translation platform since 2020. He took this responsibility after years of dedication from Claude. Thank you again for this mentorship!
