  • 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.











  • I actually even made my own bullshit-Spotify. As in, I’ve got a server running on a single-board computer which reads my music folder and serves a small music player as a webpage.

    I didn’t want to install a music player client on my work laptop, but still wanted to listen to my own songs there.




  • But that is what I mean with it needing an extension of the language.

    So, I’m not saying you could just build a library that calls existing PHP functions to make it all work. Rather I’m saying there’s certain machine code instructions, which just cannot be expressed in PHP. And we need those machine code instructions for actually managing memory. So, I am talking about reading/writing to memory not being possible, unless we resort to horrible hacks.

    Since we are building our own compiler anyways, we could add our own function-stubs and tell our compiler to translate them to those missing machine code instructions. But then that is a superset of PHP. It wouldn’t be possible in PHP itself.

    Again, I’m not entirely sure about the above, but my web search skills couldn’t uncover any way to actually just read from a memory address in PHP.


  • I mean, I’m a bit out of my water there, both in terms of the featureset of PHP and what’s actually needed for a kernel, but I’m still gonna go with no.

    For one, PHP uses reference counting + garbage collection for memory management. That’s normally done by the language runtime, which you won’t have when running baremetal.

    Maybe you could implement a kernel, which does as few allocations as possible (generally a good idea for a kernel, but no idea, if it’s possible with PHP), and then basically just let it memory leak until everything crashes.
    Then again, the kernel is responsible for making processes crash when they have a memory leak. Presumably, our PHP kernel would just start overwriting data from running processes and eventually overwrite itself in memory(?). Either way, it would be horrendous.

    Maybe you could also try to implement some basic reference counting into your own PHP code, so that your own code keeps track of how often you’ve used an object in your own code. Certainly doesn’t sound like fun, though.

    Well, and secondly, I imagine, you’d also still need an extension of the language, to be able to address actual memory locations and do various operations with them.

    I know from Rust, that they’ve got specific functions in the stdlib for that, see for example: https://doc.rust-lang.org/stable/std/ptr/index.html#functions
    Presumably, PHP does not have such functions, because its users aren’t normally concerned with that.
