  • 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.

    @Kairos@lemmy.today 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. 🙃

    I always hated that. It always felt like they just admitted defeat. They could have made an excellent song, but settled for disappointment.

    Now I’m doing music myself, and goddamn, I get it. You can have a cool song going, and then you try to end it and it just sounds like disappointment every time.

    Various ant species do a similar thing where their soldiers have really big, flat heads and when their nest gets attacked, the soldiers stick their head into the entrance way, so the attackers can’t come inside.

    Apparently, this kind of behaviour is referred to as phragmosis.



  • 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.
