  • Checks I Should Have Done Before Posting

    Sorry for the self-posting. I just wanted to share my post-hoc file checks since it was due-diligence I didn’t think of until after I shared.

    TLDR: I redirected into a file and inspected it at least enough to say I received an mkv container with an h264 video and opus audio.

    Caveats

    1. I am not in any way knowledgeable about security.
    2. You can do weird things with some files. I have no idea if mkv, opus, or h264 have comments or chimeras. See talks by Corkami for more information.
    3. Quad9 uses a dynamic TXT record to let the user know if they have configured their DNS resolver correctly, so I imagine you could receive a different file than I did. I have included a SHA-512 checksum for convenience which only tells you anything if you trust me for some reason.

    Details

    I ran the command from my post in a world-readable directory with >mystery_video_file substituted for | mpv -- - and inspected the download with

    sudo --user=nobody -- file -- mystery_video_file

    which output

    mystery_video_file: Matroska data

    I ran rename --last -- '' '.mkv' mystery_video_file # the '' is the empty string delimited with apostrophes and then

    sudo --user=nobody -- ffprobe -hide_banner -- mystery_video_file.mkv

    which output

    Input #0, matroska,webm, from ‘mystery_video_file.mkv’: Metadata: COMPATIBLE_BRANDS: isommp42 MAJOR_BRAND : mp42 MINOR_VERSION : 0 ENCODER : Lavf60.16.100 Duration: N/A, start: -0.007000, bitrate: N/A Stream #0:0: Video: h264 (High), yuv420p(tv, bt709, progressive), 256x144 [SAR 1:1 DAR 16:9], 25 fps, 25 tbr, 1k tbn (default) Metadata: HANDLER_NAME : ISO Media file produced by Google Inc.

    If you trust me and not the presenter for some inexplicable reason, the SHA-512 checksum for the video is “24345bd3ca8015c14a7d5d63d6b2a40f9d0f8c0307a65996226a496f121fa5ae934718cf58090f43ee67bc250b06804f23c73688cc871c15c1ba18d79b1a82a8”.














  • Wikipedia called these fencepost errors at one point (they now just say it is the specific type of off-by-one error in which you miscount the posts (vertices) or panels (arcs) in a fence (graph) by using one to count the other). I read this before my first programming class and then mentioned the term to my professor. She had no idea what I was talking about 😅







  • I suspect if you are trying to build an inclusive community but don’t have a lot of diversity already, the only thing you can really do to change the culture is to remind people to be considerate in the way they speak. And if most people who would be offended aren’t actually part of the community (but you would like them to feel welcome to join), then you might want some bot rather than a person to be the “narc” and remind people to be on their best behavior. So I guess if the mods are the only ones who want to be nice, then yes, it is a bit ridiculous because it will never work. Even if people change their language, they won’t be nice. But if most people want things to change, it could be a helpful way to both remind you to be inclusive and get the few people who would rather talk about how having to say bartender is censorship (without actually defending why they want to make a point of saying “barmen”) to realize that they either have to change the way they talk in that particular community or find a better fit.
