Rules

While we are not an official Mozilla community, we have adopted the Mozilla Community Participation Guidelines as far as it can be applied to a bin.

Rules

  1. Always be civil and respectful
    Don't be toxic, hostile, or a troll, especially towards Mozilla employees. This includes gratuitous use of profanity.

  2. Don't be a bigot
    No form of bigotry will be tolerated.

  3. Don't post security compromising suggestions
    If you do, include an obvious and clear warning.

  4. Don't post conspiracy theories
    Especially ones about nefarious intentions or funding. If you're concerned: Ask. Please don’t fuel conspiracy thinking here. Don’t try to spread FUD, especially against reliable privacy-enhancing software. Extraordinary claims require extraordinary evidence. Show credible sources.

  5. Don't accuse others of shilling
    Send honest concerns to the moderators and/or admins, and we will investigate.

  6. Do not remove your help posts after they receive replies
    Half the point of asking questions in a public sub is so that everyone can benefit from the answers—which is impossible if you go deleting everything behind yourself once you've gotten yours.

The current JPEG XL decoder in #Firefox apparently consists more than 100,000 lines of multi-threaded C++

For just decoding an image format.

Not sure what it says about the format, the implementation and the Internet at large.

@[email protected] To put in perspective:

  • JPEG: libjpeg 6b encoder+decoder: 24,200 lines of C
  • JPEG: libjpeg-turbo encoder+decoder: 127,000 of C and ASM (multi architectures)
  • JPEG2000: openjpeg encoder+decoder: 50,000 lines of .C
  • JPEG2000: Kakadu commercial encoder+decoder: 214,000 lines of C++ (only coresys component)
  • libjxl: 150,000 lines for the core library, encoder+decoder (deps excluded)
    (All above includes blank lines + inline doc)
    So this is pretty much standard for a modern codec
