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 be clear, this is just the reference implementation at https://github.com/libjxl/libjxl

@freddy ... and that happens to be the one Firefox uses...

@[email protected] Well, it seems that your point is "Firefox consists of bad code", whereas I believe that the conclusion from the post should be "The library is bad code, which is why we are not using it in production. We'd be happy to look at their rust implementation, when it's possible"

(footnote: "bad code" being an abbreviation of "100k multi-threaded C++")

@freddy you're reading too much into my words. I'm just amazed by how large the existing JPEG XL decoder is.

And I don't think I am alone.

@[email protected] Oh, OK. Sorry for misreading then. I'll back off. 🙂

(And yes, the existing library is... 🤯)

and "uses" in this case means "has it available behind a feature flag in their nightly builds, and does not ship it to normal users because of this very issue"
