  • Thanks for posting about this! I never thought to try this as an Akregator user, but it’s a great idea… I spent the past day getting this to work since I also use the Flatpaks; hope it helps.

    As suggested by @progandy@feddit.de, one solution is to define a custom protocol where the URL gets passed to a script that opens Firefox Reader with the URL; here’s what I’ve done:

    1. Decide on a protocol name, which the URL will be prefixed with and passed to xdg-open since that should be available to the Flatpak. I used firefox-reader as the protocol, so I put xdg-open firefox-reader://%u as the custom command (so a command Akregator would run might look like xdg-open firefox-reader://https://example.com).
    2. Define a desktop entry to support the custom protocol (you can see mine below). ~/.local/share/applications is the standard place to put these, as far as I’m aware. Since the custom protocol needs to be removed from the URL, I wrote a script (also below) to do this and then call Firefox with about:reader?url= prefixed. The script can be anywhere in $PATH.
    3. Add the desktop entry as a “default application” for opening URLs using this custom protocol. In my case, I ran xdg-mime default org.mozilla.firefox.reader.desktop x-scheme-handler/firefox-reader (org.mozilla.firefox.reader.desktop is the name of my desktop entry file).
    4. You also might have to update some mime/xdg database stuff. I had to run update-desktop-database ~/.local/share/applications so xdg-open would find the “Firefox Reader” desktop entry.
    My Firefox Reader desktop entry
    [Desktop Entry]
    Type=Application
    Name=Firefox Reader
    Exec=open-firefox-reader.sh %u
    StartupNotify=false
    MimeType=x-scheme-handler/firefox-reader;
    
    open-firefox-reader.sh script
    #!/usr/bin/env bash
    
    flatpak run --user org.mozilla.firefox about:reader?url="${1#firefox-reader://}"
    

    If you have any other trouble or want to find more information about this since the desktop entry could probably be tweaked, here are the sources of note I used to figure this out (If I forgot a step or two writing this, they should also be present somewhere in there):


  • I’ve been having my own fun trying out NVK on Guix System so I can’t give you specific instructions (assuming you’re not using Guix), but I can tell you what you need and maybe someone else can chip in on how/if you need to do anything else on your distro:

    • Linux kernel >= 6.7
    • GSP firmware enabled via the kernel parameter nouveau.config=NvGspRm=1
    • Mesa built with the -Dvulkan-drivers=nouveau-experimental flag.

    A few notes:

    • Performance and stability of games has been fairly hit-or-miss for me. Of the 10 Vulkan games I’ve tried so far: 3 run perfectly, 3 are playable with noticeable issues, and 4 are borked.
    • NVK is Vulkan-only, but performance largely comes from the GSP firmware so you will still see a difference (huge for me) in games not using Vulkan.
    • You can override flatpaks to use the host’s Mesa version (set FLATPAK_GL_DRIVERS=host); however, there’s a bug that causes the Steam Flatpak to not work when doing this. The mesa-git-extension Flatpak exists which can also be used to replace Mesa runtimes, but it had issues building with NVK so it’s currently disabled.

    The only package I’m aware of at the moment (other than my hacked-together Guix package) is available in the AUR.


  • I use git-annex and Guix (particularly Guix Home in this case) for managing all of my data, including dotfiles. git-annex handles syncing (and backups via delivery to a Borg repo) and version management as git does, while Guix takes care of installing programs and setting up configuration files.

    I previously wrote a custom Guix service that utilized Stow as well for managing writable files, but have since replaced it with another custom Guix service that handles some cleanup processes better.

    Depending on how much you want simplicity of restoration, this approach might be on the heavier side since it’s concerned with a lot more than just dotfiles. You could replace git-annex with git to simplify the syncing part if you’re only interested in managing configuration files, though. Here’s what my Guix config looks like; the readme file shows how I would set up a system from scratch.



  • The CryFS developers have a comparison page here that might help you decide what to use. There’s a summary table at the bottom that gives a comparison of features between encryption filesystems if you don’t feel like reading through it all.

    I personally use and would recommend CryFS because it’s the only one (that I’m aware of) that plays nice with data synchronization software (i.e. doesn’t store the container as a single file) while keeping the directory structure encrypted.


  • Does Guix fit your criteria, perhaps? If you haven’t heard of it, you can think of it as Nix with a Lisp frontend.

    I unfortunately am not very experienced with containerizing packages so I can’t say much, but I know you can do it; the Nonguix channel employs containers for some proprietary software.

    Like Nix, Guix has all that building-from-source stuff you’d want from Gentoo. There’s recently been work on making parameterized packages (the Guix equivalent of USE flags) a thing, but it’s still work-in-progress.

    Ignoring the steep upfront cost of learning it, I’d say Guix makes it incredibly easy to add your own packages. Here’s the custom packages I currently have in my dotfiles repository. I can import one to my main config file, add the package, and it gets included in my environment the next time I reconfigure it.

    As for patches, I can’t make any comparisons since I’m not familiar with Gentoo, so I think a code snippet is probably better for you to judge if you’d like it.

    Here's a minimal example:
    (define-public custom-pkg
      (package
        (inherit pkg)
        (name "custom-pkg")
        (version (package-version pkg))
        (source (origin
                  (inherit (package-source pkg))
                  (patches
                   (list (string-append (dirname (current-filename))
                                        "/fix-some-thing.patch")))))))
    

    EDIT: Here’s the less verbose version, which you can use instead if all you’re doing is adding patches.

    (define-public custom-pkg
      (package-with-patches
       pkg
       (list (string-append (dirname (current-filename))
                            "/fix-some-thing.patch"))))
    

    Not sure if this addresses your concern about multi-architecture support, but the Foreign Architectures section of the manual discusses what you can build to.

    EDIT: So I was curious after posting this because usually the CLI often has much less verbose options (like --with-input for replacing inputs), and I started wondering if there was any procedure that would make this simpler. Turns out there is :) I’ve included it under the example. Although, I suppose I should have mentioned you could write your own if you really wanted to.







  • I remember having this issue, albeit not as workflow-disrupting as you’ve had it so I never bothered actively searching for a solution. I can confirm however that there is definitely a solution; at some point in my migrations to different distros, the problem stopped showing up, and right now I actually can’t reproduce the problem - labels are displayed correctly for me, both on my existing drives and new partitions that I create.

    After some digging (and a sleep-deprived me smiting my boot partition during my investigation and having to fix that, LMAO - I never thought it’d happen, but Guix saved me from a reinstall), I found that LUKS1 has some kind of limitation that makes Dolphin not display the label as expected according to this and my own testing, which may be your problem if your drives are still using LUKS1. The Arch Wiki has a section on how to convert to LUKS2 here.

    At the very least, if this is not the solution for you, I can say with certainty that it is fixable!
