  • 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 personal project I’m currently working on the most is Nucom, an implementation of Microsoft’s Component Object Model.

    The IDL compiler for it, which takes .idl files which define COM interfaces and outputs C/C++ headers/source files and Rust modules, is written in Rust.

    Originally, this project was all C++, and everything but the compiler still is (which also likely isn’t going to change since it involves building dynamic libraries which Rust does not do well at all), but I really did not want to go without Rust when writing a parser/compiler type thing because the language is so much nicer to work with.


  • The disks are the most uggo part. They’re a bunch of old disks of varying sizes with a RAID+LVM setup to make the most use of them while still being redundant.

  • 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)?])
    }
    





  • Yep. Lack of format support is usually to blame on the one who doesn’t support the format. You can absolutely blame Apple for this too though, their apps can’t open e.g. Matroska video or FLAC.

    And perplexingly, they don’t support uploading HEIC, their own image format of choice, on the web iCloud Photos. So there’s that too.

    (At this point my music library is stored as ALAC because it’s well supported in both Linux and Apple’s OSes. Really wish it wouldn’t have to be that way though. Someone needs to tell them about ffmpeg.)

    For example they used to have their own video container .mov

    It’s always very very funny every time someone mentions MOV, because while it’s very similar to MP4, it’s actually an open format while MP4 isn’t (!). You actually have to pay for the MP4 standard document while Apple just gives you the MOV documentation.

    Also at least taking a screen capture on macOS still gives you a MOV container, actually.
