  • But is it backwards compatible with an old version that can't be updated?

    I'll tell you if I can find some new files for testing.

    Even JPEG isn't always back compatible either. I loaded an image into my software which uses some ancient library internally, and it swapped the blue and red channels.

    Now if anyone don't mind explaining, PNG vs JXL?

  • It's not irrelevant, it's that you don't actually know if it's true or not, so it's not a valuable contribution.

    If you started your comment by saying "This is something I completely made up and may or may not be correct" and then posted the same thing, you should expect the same result.

    I did check some of the references.

    What I dont understand is why you would perceive this content as more trustworthy if I didn't say it's AI.

    Nobody should trust blindly some anonymous comment on a forum. I have to check what the AI blurbs out but you can just gobble the comment of some stranger without exercising yourself some critical thinking?

    As long as I'm transparent on the source and especially since I did check some of it to be sure it's not some kind of hallucination...

    There shouldn't be any difference of trust between some random comment on a social network and what some AI model thinks on a subject.

    Also it's not like this is some important topic with societal implications. It's just a technical question that I had (and still doesn't) that doesn't mandate researching. None of my work depends on that lib. So before my comment there was no information on compatibility. Now there is but you have to look at it critically and decide if you want to verify or trust it.

    That's why I regret this kind of stubborn downvoting where people just assume the worse instead of checking the actual data.

    Sometime I really wonder if I'm the only one supposed to check my data? Aren't everybody here capable of verifying the AI output if they think it's worth the time and effort?

    Basically, downvoting here is choosing "no information" rather than "information I have to verify because it's AI generated".

    Edit: Also I could have just summarized the AI output myself and not mention AI. What then? Would you have checked the accuracy of that data? Critical thinking is not something you use "sometimes" or just "on some comments".

  • Likely, you'll see the first frame only on older software. Encoding animation in a dedicated animation chunk and using the base spec for the first keyframe sounds like the sane thing to do, so they likely did that.

    I'm not going to look into it now, because I would then have to implement it. 😄

    Haha dont worry, just curious. Your answer is good!

    You realize that if we wanted to see an AI LLM response, we'd ask an AI LLM ourselves.
    What you're doing is akin to :

    Hey guys, I've asked google if the new png is backward compatible, and here are the first links it gave me, hope this helps : [list 200 links]

  • Now if anyone don't mind explaining, PNG vs JXL?

    JXL is badly supported but it does offer lossless encoding in a more flexible and much more efficient way than png does

    Basically jxl could theoretically replace png, jpg, and also exr.

  • I don't know. If the poster couldn't be bothered to fact-check, why would I? It is just safer to assume that it can be misinformation.

    If you prefer to know nothing about PNG compatibility rather than something that might be true about PNG. That's fine but definitely not my approach.

    Also, as I said to another commenter. Critical thinking is not some tool you decide to use on some comments and not others. An AI answer on some topics is actually more likely to be correct than an answer by a human being. And it's not some stuff I was told by an AI guru it's what researchers are evaluating in many universities. Ask an human to complete various tasks and then ask the AI model and compare scientifically the data. And it turns out there is task where the AI outperforms the human pretty much all the time.

    YET on this particular task the assumption is that it's bullshit and it's just downvoted. Now I would have posted the same data myself and for some reason I would not see a single downvote. The same data represented differently completely change the likelihood of it being accurate. Even though at the end of the day you shouldn't trust blindly neither a comment from an human or an AI output.

    Honestly, I'm saddened to see people already rejecting completely the technology instead of trying to understand what it's good at and what it's bad at and most importantly experiencing it themselves.

    I wanted to know what was generative AI worth so I read about it and tried it locally with open source software. Now I know how to spot images that are AI generated, I know what's difficult for this tech and what is not. I think that's a much healthier attitude than blindly rejecting any and all AI outputs.

  • Ooh, that was the coaster company, I remember them.

  • That depends. Something like HDR should be able to fall back to non-HDR since it largely just adds data, so if the format specifies that extra information is ignored, there's a chance it works fine.

    I'm not sure you can turn an hdr image into a regular one just by snipping it down to 8 bits per channel and discarding the rest.

    I mean it would work but I'm not certain you'll get the best results.

  • JXL is badly supported but it does offer lossless encoding in a more flexible and much more efficient way than png does

    Basically jxl could theoretically replace png, jpg, and also exr.

    Interestingly, I downloaded GNOME's pride month wallpaper to see what it looked like, and the files were JXL. Never seen them in the wild before that

    it would work

    And that's probably enough. I don't know enough about HDR to know if it would look anything like the artist imagined, but as long as it's close enough, it's fine if it's not optimal. Having things completely break is far less than ideal.

  • it would work

    You'd probably get some colours that end up being quite off target. But you'll get an image to display. So in the end it depends on how much "not optimal" you're ready to accept.

    I understand that. It's the downvoting of the clearly marked as AI LLM response. Is it detrimental to the conversation here to have that? Is it better to share nothing rather than this LLM output?

    Was this thread better without it?

    Is complete ignorance of the PNG compatibility preferable to reading this AI output and pondering how true is it?

    [list 200 links]

    Now I think this conversation is getting just rude for no reason.
    I think the AI output was definitely not the "I'm lucky" result of a Google search and the fact that you choose that metaphor is in bad faith.

    Yes.

    I, and I assume most people, go into the comments on Lemmy to interact with other people. If I wanted to fucking chit-chat with an LLM (why you'd want to do that, I can't fathom), I'd go do that. We all have access to LLMs if we wish to have bullshit with a veneer of eloquency spouted at us.

  • You'd probably get some colours that end up being quite off target. But you'll get an image to display. So in the end it depends on how much "not optimal" you're ready to accept.

    Right, and it depends on what "quite off target" means. Are we talking about greens becoming purples? Or dark greens becoming bright greens? If the image is still mostly recognizable, just with poor saturation or contrast or whatever, I think it's acceptable for older software.

    Are you really asking why advertising that "the following comment may be hallucinated" nets you more downvotes than just omitting that fact?

    You're literally telling people "hey, this is a low effort comment" and acting flabbergasted that it gets you downvotes.

    PNG, like "PNG"

    So why "research" it with AI in the first place, if you don't care about the results and don't even think it's worth researching? This is legitimately absurd to read.

    This would be better suited in some casual ranting community. Or one concerned with tech bros. I think it's completely off topic here.

    It is common in the military to give commissioned rank to certain positions for the higher pay grade. The fast tracking takes away from the belief everyone serving with you went through (roughly) the same basic training as you.

    AFAIK, you have the option to enable ads on your lock screen. It's not something that's forced upon you. Last time I took a look at the functionality, they "paid" you for the ads and you got to choose which charity to support with the money.

    The topic is more nuanced, all the logs indicate email/password combos that were compromised. While it is possible this is due to a malware infection, it could be something as simple as a phishing website. In this case, credentials are entered but no "malware" was installed. The point being it doesn't look great that someone has ANY compromises... But again, anyone who's used the Internet a bit has some compromised. For example, in a password manager (especially the one on iPhone), you'll often be notified of all your potentially compromised accounts. [image: 7a5e8350-e47e-4d67-b096-e6e470ec7050.jpeg]

    Only way I'll want a different phone brand is if it comes with ZERO bloatware and has an excellent internal memory/storage cleanse that has nothing to do with Google's Files or a random app I'm not sure I can trust without paying or rooting. So far my A series phones do what I need mostly and in my opinion is superior to the Motorola's my fiancé prefers minus the phone-phone charge ability his has, everything else I'm just glad I have enough control to tweak things to my liking, however these days Samsungs seem to be infested with Google bloatware and apps that insist on opening themselves back up regardless of the widespread battery restrictions I've assigned (even was sent a "Stop Closing my Apps" notif that sent me to an article ) short of Disabling many unnecessary apps bc fully rooting my devices is something I rarely do anymore. I have a random Chinese brand tablet where I actually have more control over the apps than either of my A series phones whee Force Stopping STAYS that way when I tell them to! I hate being listened to for ads and the unwanted draining my battery life and data (I live off-grid and pay data rates because "Unlimited" is some throttled BS) so my ability to control what's going on in the background matters a lot to me, enough that I'm anti Meta-apps and avoid all non-essential Google apps. I can't afford topline phones and the largest data plan, so I work with what I can afford and I'm sad refurbished A lines seem to be getting more expensive while giving away my control to companies. Last A line I bought that was supposed to be my first 5G phone was network locked, so I got ripped off, but it still serves me well in off-grid life. Only app that actually regularly malfunctions when I Force Stop it's background presence is Roku, which I find to have very an almost insidious presence in our lives. Google Play, Chrome, and Spotify never acts incompetent in any way no matter how I have to open the setting every single time I turn Airplane Mode off. Don't need Gmail with Chrome and DuckDuckGo has been awesome at intercepting self-loading ads. I hope one day DDG gets better bc Google seems to be terrible lately and I even caught their AI contradicting itself when asking about if Homo Florensis is considered Human (yes) and then asked the oldest age of human remains, and was fed the outdated narrative of 300,000 years versus 700,000+ years bipedal pre-humans have been carbon dated outside of the Cradle of Humanity in South Africa. SO sorry to go off-topic, but I've got a big gripe with Samsung's partnership with Google, especially considering the launch of Quantum Computed AI that is still being fine-tuned with company-approved censorships.
