I’m interested in #Linux, #FOSS, data storage/management systems (#btrfs, #gitAnnex), unfucking our society and a bit of gaming.

I help maintain #Nixpkgs/#NixOS.

  • You can do it but I wouldn’t recommend it for your use-case.

    Caching is nice but only if the data that you need is actually cached. In the real world, this is unfortunately not always the case:

    1. Data that you haven’t used it for a while may be evicted. If you need something infrequently, it’ll be extremely slow.
    2. The cache layer doesn’t know what is actually important to be cached and cannot make smart decisions; all it sees is IO operations on blocks. Therefore, not all data that is important to cache is actually cached. Block-level caching solutions may only store some data in the cache where they (with their extremely limited view) think it’s most beneficial. Bcache for instance skips the cache entirely if writing the data to the cache would be slower than the assumed speed of the backing storage and only caches IO operations below a certain size.

    Having data that must be fast always stored on fast storage is the best.

    Manually separating data that needs to be fast from data that doesn’t is almost always better than relying on dumb caching that cannot know what data is the most beneficial to put or keep in the cache.

    This brings us to the question: What are those 900GiB you store on your 1TiB drive?

    That would be quite a lot if you only used the machine for regular desktop purposes, so clearly you’re storing something else too.

    You should look at that data and see what of it actually needs fast access speeds. If you store multimedia files (video, music, pictures etc.), those would be good candidates to instead store on a slower, more cost efficient storage medium.

    You mentioned games which can be quite large these days. If you keep currently unplayed games around because you might play them again at some point in the future and don’t want to sit through a large download when that point comes, you could also simply create a new games library on the secondary drive and move currently not played but “cached” games into that library. If you need it accessible it’s right there immediately (albeit with slower loading times) and you can simply move the game back should you actively play it again.

    You could even employ a hybrid approach where you carve out a small portion of your (then much emptier) fast storage to use for caching the slow storage. Just a few dozen GiB of SSD cache can make a huge difference in general HDD usability (e.g. browsing it) and 100-200G could accelerate a good bit of actual data too.



  • If I can’t find something I can just add a quick !g to my already existing query and look it up on Google instead, which I’ve found rather convenient.

    Yeah I used to do the same (but with !s).

    It’s much more convenient to just have good search results to begin with though. Kagi uses the Google index and a few others and you have your own filtering and ranking on top.

    In the beginning I felt tempted to do !s a few times too but the results were always worse, so I quickly unlearned doing that.

    Executing bangs is also a lot quicker with Kagi; DDG is kind of a slog.








  • If you talk about “a GUI for systemd”, you obviously mean its most central and defining component which is the service manager. I’m going to assume you’re arguing in bad faith from here on out because I consider that to be glaringly obvious.

    systemd-boot still has no connection to systemd the service manager. It doesn’t even run at the same time. Anything concerning it is part of the static system configuration, not runtime state.
    udevd doesn’t interact with it in any significant user-relevant way either and it too is mostly static system configuration state.

    journald would be an obvious thing that you would want integrated into a systemd GUI but even that could theoretically be optional. Though it’d still be useful without, it would diminish the usefulness of the systemd GUI significantly IMHO.
    It’s also not disparate at all as it provides information on the same set of services that systemd manages and i.e. systemctl has journald integration too. You use the exact same identifiers.




  • As mentioned, those are entirely separate and even independent components.

    Systemd (as in: pid1) only “manages” them insofar as that it controls their running processes just like any other service on your system.

    systemd-boot doesn’t interact with systemd at all; it’s not even a Linux program.

    The reason these components have “systemd” in their name is that these components are maintained by the same people as part of the greater systemd project. They have no further relation to systemd pid1 (the service manager).

    Whoever told you otherwise milead you and likely had an agenda or was transitively mislead by someone who does. Please don’t spread disinformation further.
