  • I mean, these communities do get created when someone feels like there’s a reason to. There’s just no council or whatever regulating when and where a community gets to be created, so any user on any instance can decide to open up and promote their community.

    And frankly, I have no idea what the precise effects are. When you subscribe to all of these, it won’t really be much different from just one big community in that sense. It may mean, though, that someone new accidentally joining only one of the communities will not be presented all the content they want, yeah.

    On the flip side, having it split is kind of cool, because you can decide to only subscribe to 2 out of 4 communities, if you only want half as much of this content in your feed. Or you can decide to subscribe to all of these, but not to the one on angry-instance.net, because you don’t like the tone of the discussions in that one.


  • Yeah, it’s federated, meaning you can subscribe to each of them and post to whichever one you fancy. If you want to post to multiple, it’s a good idea to use the cross-post feature.

    Having only one singular official community would be rather bad, as then the respective server owners and moderators would have central control like on Reddit.


  • Hmm, yeah, it is a bit surprising to me, too, especially for an audio issue, but it’s always possible that you had some weird configuration values in about:config for historic reasons and now some new code, that came in with a Firefox update, isn’t working with that configuration.

    Either way, it happens often enough that Mozilla has a troubleshooting routine for it, too, namely refreshing your profile.

    If I remember correctly, it places your old profile data into a folder in your Desktop folder. But you can also separately backup your profile by closing Firefox and then copying ~/.mozilla/firefox/ onto an external hard drive or such.

    Completely unrelated story: I bought a red cabbage last week and was so glad to have found a relatively small one in the shop.

    …I have been eating red cabbage for the past three days and still have enough left for another two days. Just why is it so damn compressed? I can cut off the tiniest slice from that cabbage and it still fills a whole plate.







  • I have no idea about MIDI controllers using keyboard keys, but it seems quite popular for DAWs and similar software to support this. I’ve tried LMMS, Ardour and MilkyTracker so far and they all had it.
    For quickly trying out a melody/chord, I also like to keep VMPK installed, which is basically just a software to play piano on your PC keyboard. I believe, it could also be hooked up like a MIDI controller to DAWs.

    I will say that using a PC keyboard for this does not always work terribly well, since most PC keyboards are not built for pressing many keys at the same time. They will just not accept certain keys being pressed together.
    There is PC keyboards with “n-key rollover” which don’t have this problem, but you might as well get a proper MIDI piano keyboard at that point…




  • Yeah, that is my understanding, too. Otherwise you’d only want to generate them on the database host, as even with NTP there will be small differences. This would kind of defeat the purpose of UUIDs.

    If you’re saying that even without NTP, just by manually setting the time, things will be fine. I mean, maybe. But I’ve seen it far too many times already that some host shows up with 1970-01-01…


  • For others wondering what’s wrong with UUIDv4:

    UUID versions that are not time ordered, such as UUIDv4, have poor database-index locality. This means that new values created in succession are not close to each other in the index; thus, they require inserts to be performed at random locations. The resulting negative performance effects on the common structures used for this (B-tree and its variants) can be dramatic.

    I guess, this means with these new UUIDs, ideally you only create UUIDs on systems that are hooked up to NTP, though I guess, it won’t really be worse than UUIDv4 either way.


  • We’ve been using Leptos at work, which is a similar framework (and probably shares half the stack with Dioxus).

    And yeah, it’s really good. My favorite thing about using Rust for the UI is algebraic data types.
    So, in Rust when you call a function which can fail, there isn’t an exception being thrown, but rather you get a Result-type as return value.
    This Result can either contain an Ok with the actual return value inside. Or it can contain an Err with an error message inside.
    So, in your UI code, you just hand this Result all the way to your display code and there you either display the value or you display the error.

    No more uninitialized variables, no more separate booleans to indicate that the variable is uninitialized, no more unreadable multi-line ternaries.
    It just becomes so much simpler to load something from the backend and display it, which is kind of important in frontend code.




  • Fading out? With my wind band, we’ve never done it.
    You can have everyone play pianissimo and also reduce how many players play each voice, but unlike a digital fade, this does change the way it sounds.
    It’s also difficult to stay in tune when playing at a low volume with a wind instrument, so it starts to sound horrible before it becomes inaudible.

    @[email protected] mentioned mic+soundboard, but for a windband, the band itself would need to be out of earshot, which is rarely possible.

    So, yeah, if we ever need/want to cut a song short, we make use of a marching band signal.
    Basically, the person on bass drum does two double-hits, which are out of rhythm so you can hear them, and then another hit on the first beat of the next measure, which is when everyone stops playing.
    That does not always sound great either, but better than nosediving the whole orchestra. 🙃
