if you could pick a standard format for a purpose what would it be and why?

e.g. flac for lossless audio because...

(yes you can add new categories)

summary:

  1. photos .jxl
  2. open domain image data .exr
  3. videos .av1
  4. lossless audio .flac
  5. lossy audio .opus
  6. subtitles srt/ass
  7. fonts .otf
  8. container mkv (doesnt contain .jxl)
  9. plain text utf-8 (many also say markup but disagree on the implementation)
  10. documents .odt
  11. archive files (this one is causing a bloodbath so i picked randomly) .tar.zst
  12. configuration files toml
  13. typesetting typst
  14. interchange format .ora
  15. models .gltf / .glb
  16. daw session files .dawproject
  17. otdr measurement results .xml

By separating the jobs of archiving (.tar), compressing (.zst), and (if you so choose) encrypting (.gpg), .tar.zst follows the Unix philosophy of “Make each program do one thing well.”.

The problem here being that GnuPG does nothing really well.

Videos (Codec): AV1

  • Much more efficient than x264 (used by .mp4) and VP9[3].

AV1 is also much younger than H264 (AV1 is a specification, x264 is an implementation), and only recently have software-encoders become somewhat viable; a more apt comparison would have been AV1 to HEVC, though the latter is also somewhat old nowadays but still a competitive codec. Unfortunately currently there aren't many options to use AV1 in a very meaningful way; you can encode your own media with it, but that's about it; you can stream to YouTube, but YouTube will recode to another codec.

    Could you elaborate? I've never had any issues with gpg before and curious what people are having issues with.

    Unfortunately currently there aren’t many options to use AV1 in a very meaningful way; you can encode your own media with it, but that’s about it; you can stream to YouTube, but YouTube will recode to another codec.

    AV1 has almost full browser support (iirc) and companies like YouTube, Netflix, and Meta have started moving over to AV1 from VP9 (since AV1 is the successor to VP9). But you're right, it's still working on adoption, but this is moreso just my dreamworld than it is a prediction for future standardization.

    This article and the blog post linked within it summarize it very well.

    Encrypting Email

    Don’t. Email is insecure . Even with PGP, it’s default-plaintext, which means that even if you do everything right, some totally reasonable person you mail, doing totally reasonable things, will invariably CC the quoted plaintext of your encrypted message to someone else

    Okay, provide me with an open standard that is widely-used that provides similar functionality.

    It isn't there. There are parties who would like to move email users into their own little proprietary walled gardens, but not a replacement for email.

    The guy is literally saying that encrypting email is unacceptable because it hasn't been built from the ground up to support encryption.

    I mean, the PGP guys added PGP to an existing system because otherwise nobody would use their nifty new system. Hell, it's hard enough to get people to use PGP as it is. Saying "well, if everyone in the world just adopted a similar-but-new system that is more-amenable to encryption, that would be helpful", sure, but people aren't going to do that.

    The message to be taken from here is rather "don't bother", if you need secure communication use something else, if you're just using it so that Google can't read your mail it might be ok but don't expect this solution to be secure or anything. It's security theater for the reasons listed, but the threat model for some people is a powerful adversary who can spend millions on software to find something against you in your communication and controls at least a significant portion of the infrastructure your data travels through. Think about whistleblowers in oppressive regimes, it's absolutely crucial there that no information at all leaks. There's just no way to safely rely on mail + PGP for secure communication there, and if you're fine with your secrets leaking at one point or another, you didn't really need that felt security in the first place. But then again, you're just doing what the blog calls LARPing in the first place.
