  • I’ve been using Linux for maybe 8 years before getting a Mac and found it to be great to use pretty much immediately. So there’s not really much I can tell you here. Except maybe to install the GNU coreutils from homebrew (and that itself if you don’t have it yet), the ones it comes with suck.

    I don’t think there is a way to download Xcode without an Apple ID. The App Store also needs one though you could get by without that. You could just make the account only for downloading Xcode and only sign in in the browser for it, I suppose.

    Edit: Oh yeah, get Mac Mouse Fix if you plan on using it with a normal mouse. The standard scrolling behavior is abysmal.



  • The bingo one actually uses crossbeam channels instead of mutexes, so that’s nice. I haven’t looked too closely at it though.

    I don’t think you can do too much about the Spectrum one if you want to keep the two threads, but here’s what I would change related to thread synchronization. Lemmy doesn’t seem to allow me to attach patch files for whatever reason so have an archive instead… https://dblsaiko.net/pub/tmp/patches.tar.bz2 (I wrote a few notes in the commit messages)

    Just to give the reason for Rc<RefCell> in the current project. I’m reading in a M3U file and I’m going to be referencing it against an Excel file. So in the structure for the m3u file, I have two BtreeMaps, one for order by channel number and one by name. Each containing references to the same Channel object.

    So basically it’s channels indexed by channel number and name? That one is actually one of the easy cases. Store indices instead:

    struct Channels {
      data: Vec<Channel>,
      by_number: BTreeMap<u32 /* or whatever */, usize>,
      by_name: BTreeMap<String, usize>,
    }
    
    // untested but I think it should compile
    fn get_channel_by_name(ch: &Channels, name: &str) -> Option<&Channel> {
      Some(&self.data[*ch.by_name.get(name)?])
    }
