  • Oof, I was just talking about making things declarative there. If you want to configure it the old-fashioned way, like you would on other distros, then those difficulties don’t apply.

    In more general terms, though, it’s a bit of a double-edged sword. The Nix package repository has more packages than other package managers: https://repology.org/repositories/graphs

    So, the chance of finding an obscure software, that’s already packaged, is rather high.
    Here’s the online package search, if you want to check the availability of some of the obscure software you use: https://search.nixos.org/packages

    But then, yeah, the flipside is that, from what I understand, you can’t just download a random executable off of the internet and run it, because of the Filesystem Hierarchy Standard not being adhered to, as the post also mentions.
    You can set up Flatpaks, and I believe AppImages would work, because those also live in their own FUSE filesystem. Well, and there is ways to emulate the FHS layout to get normal applications to run, too.

    But yeah, way out of my field of expertise there. I have only one software installed which isn’t packaged for Nix, which is a program I wrote myself.
    And to get sufficient FHS emulation for that, I just needed this line in my config:

    programs.nix-ld.enable = true;
    

    More complex programs will need a bit of extra configuration: https://wiki.nixos.org/wiki/Nix-ld

    (I could also add a flake.nix file into my software’s repository, though, which would make it so it could be installed straight from my repo, as if it was packaged.)




  • Oh wow, what the hell. I’m not actually familiar with C++ (just with Rust which gets similar reactions with the ampersands), but that’s insane that it just copies shit by default. I guess, it comes from a time when people mostly passed primitive data types around the place. But yeah, you won’t even notice that you’re copying everything, if it just does it automatically.

    And by the way, Rust did come up with a third meaning for passing non-references: It transfers the ownership of the object, meaning no copy is made and instead, the object is not anymore allowed to be used in the scope that passed it on.
    That’s true, except for data types which implement the Copy trait/interface, which is implemented mostly for primitive data types, which do then get treated like C++ apparently treats everything.


  • Yeah, I can understand the frustration. IMHO the Home-Manager way of doing things has some merits:

    • You can (generally) manage the installation of packages together with their configuration.
    • You can override individual configuration values for different machines (which I guess, you can also do via templating in chezmoi).
    • Some programs don’t have a particularly readable configuration file or spread this configuration out over multiple files, or save all kinds of additional garbage into their configuration file which you don’t want to persist. Home-Manager can work around all these issues, and in such a case is likely also better documented than the original configuration file.

    That last point is one that’s particularly relevant for me, because KDE Plasma’s configuration files are largely terrible. Home-Manager, together with Plasma-Manager, is the only sane way I know of, to automate the panel configuration in KDE.

    But yeah, if you don’t use software with terrible configuration files, then I can certainly understand preferring dumb templating. I have also decided against using the Home-Manager-specific modules in places, or might only translate into the Home-Manager-specific module when I actually want to vary configuration values between two machines.


    Just to give a quick impression of how terrible the KDE panel configuration is, this is a snippet out of the fittingly-called plasma-org.kde.plasma.desktop-appletsrc file:

    [ActionPlugins][0]
    MiddleButton;NoModifier=org.kde.paste
    RightButton;NoModifier=org.kde.contextmenu
    
    [ActionPlugins][1]
    RightButton;NoModifier=org.kde.contextmenu
    
    [Containments][1122]
    activityId=f588743a-9bab-4f56-8f90-3616085ab6e0
    formfactor=0
    immutability=1
    lastScreen=1
    location=0
    plugin=org.kde.plasma.folder
    wallpaperplugin=org.kde.color
    
    [Containments][1122][Wallpaper][org.kde.color][General]
    Color=#79740e
    

    Ah sorry, that doesn’t actually show any of the panel configuration, because KDE mixes configuration for the panel and desktop widgets and the Activities feature (like workspaces, but with separate wallpapers and widgets for each Activity) all into the same file.
    So, here’s a snippet that actually shows the panel configuration, from just a few lines below the first snippet:

    [Containments][1807]
    activityId=
    formfactor=3
    immutability=1
    lastScreen[$i]=0
    location=5
    plugin=org.kde.panel
    wallpaperplugin=org.kde.image
    
    [Containments][1807][Applets][1808]
    immutability=1
    plugin=org.kde.plasma.showActivityManager
    
    [Containments][1807][Applets][1810]
    immutability=1
    plugin=org.kde.plasma.pager
    
    [Containments][1807][Applets][1810][Configuration][General]
    showOnlyCurrentScreen=true
    showWindowIcons=true
    wrapPage=true
    
    [Containments][1807][Applets][1811]
    immutability=1
    plugin=org.kde.plasma.panelspacer
    
    [Containments][1807][Applets][1812]
    activityId=
    formfactor=0
    immutability=1
    lastScreen=-1
    location=0
    plugin=org.kde.plasma.systemtray
    popupHeight=432
    popupWidth=432
    wallpaperplugin=org.kde.image
    

    What those numbers in e.g. [Containments][1807][Applets][1812] are? Ah, they just count those from 0 to infinity, whenever you add a widget through the UI.
    And in case you were wondering since when INI allows for nesting section keys via [multiple][brackets]: It doesn’t. That’s a custom extension of the INI format, specifically in use by KDE.

    Like, man, I love KDE for its features, but this is the stuff of nightmares.








  • Well, specifically because the conversions are so trivial, decimeters aren’t inherently more useful than specifying tens of centimeters. And with measurements of smaller lengths, you usually do need centimeter precision, so 57cm is simpler than 5.7dm or 5dm 7cm.

    Well, and sometimes you also need millimeters, so 57.5cm is still conceptually simpler (57½cm) than 5.75dm.

    All these combined mean that centimeters end up being used much more often. And then decimeters fell out of use even where it would still be a fitting unit (8dm instead of 80cm), because our brains work in patterns and will retain those patterns better that are used/trained more often.

    I know conceptually what decimeters are, but if you tell me something is 8dm long, it does take a splitsecond for me to mentally convert that into 80cm, which is where all my brain’s patterns have been trained on. I have an intuition what “80cm” looks like in the real world, whereas I don’t for “8dm”, not without mentally converting it to cm.

    One time, I was staring at a piece of code for a solid 10 minutes or so, and could not understand why it gave me a compile error.
    So, I ask the senior for help, start explaining what I’ve been trying to do, scroll down to show some other code snippet, scroll back up and the compile error was gone. My IDE simply had not re-rendered properly. I have rarely sweared as much as in that moment.


  • This is a somewhat hacky solution, but I’ve set up a thing in the past, where I would share a URL to my desktop via KDE Connect. And then on my desktop, I configured the default browser to be a script that I wrote.
    This script would check, if the URL is a YouTube URL, and if so then open it via MPV (with yt-dlp also installed on the system).
    If not, then just open it in Firefox as normal.


  • That’s really not a good sign, though. A review process to check for basic sanity is just a bandaid fix for a lack of discipline, which ultimately requires more work to be done. So, the person that asked the magic pattern machine should review that code, as they should be deeper into the context of what needs to be done, and they know which parts of the code were generated and which parts they actually logically thought about.
