No such thing. Ask away!

!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must be legitimate questions. All post titles must include a question.

All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.



Rule 2- Your question subject cannot be illegal or NSFW material.

Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.



Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here.

I don't know what a .webp file is but I don't like it. They're like a filthy prank version of the image/gif you're looking for. They make you jump through all these hoops to find the original versions of the files that you can actually do anything with.

Edit: honestly I assumed it had something to do with Google protecting themselves from image piracy shit

I think PNG is a good format even today. It's lossless compressed, so there isn't that much you can squeeze out of that with new algorithms as you can out of lossy formats with new and smarter approaches.

Sadly, PNG is being terribly misused on the internet too. What it's good for is simple drawn graphics, which it can compress to oblivion. So it's perfect for screenshots of say, your operating system's windows. I took a sshot as I'm typing this, and it came out as 190 kB. Not bad.

But what it's so commonly used for, is people taking screenshots of photos such as from Instagram, and then reposting them. So instead of a tiny and shitty 50 kB IG picture, you get a 1.5MB PNG screenshots. Some then recompress it to a 1.5MB JPG for "maximum quality" when they realise they can't upload PNG to photo sites.

I also very often encounter huge PNG photos with their extensions changed to JPG, and I don't know how or why that is happening.

This one really grinds my gears. Why do so many people insist on sharing text by taking a picture instead of pasting the text? Or better yet, just linking to the original? It's such a waste of bandwidth :(

Probably people uploading to sites that limit extensions thinking they're clever by just changing the extension, or being straight up wrong in thinking the extension changing actually changes the file type.

The sites might not bother to check the metadata, and anything worth any salt that displays the image will ignore the extension anyway.

[–] [email protected] 2 points 1 year ago (1 children)

That sounds logical, but on most operating systems these days the extension is hidden, and/or you need to go through some hoops to change it. So I would think that most people who think that wouldn't even know how to change it.

But more importantly, where do those PNGs come from in the first place? Sure, some are clearly screenshots such as of IG or TT, but there are tons of large PNG images that are clearly photos from cameras that someone just took and resaved as png (and later, or someone else, then renamed to jpg).

I could understand that happening occasionally for a bunch of reasons, but I've encountered this so many times, it's pretty bizarre.

Btw it's something you might not even notice if you aren't using e.g. an image viewer that uses a different icon or background based on actual image type.

[–] [email protected] 1 points 1 year ago (2 children)

I suppose another solution might be that it falls under those lines, but some misbehaving services where they're uploaded are giving out improper filenames and not confirming the type.

Though I can't imagine many of those being incredibly popular, or, it's just that images are recycled for so long that eventually many of them hit such a site in their lifetimes.

Yet you still posted it in jpeg. Can't fool me with your sly tricks.

Just for you, I turned it into webp and made it 40KB. I could have also made it look less like garbage, but then it would have been 50KB, which is unacceptable.

[–] [email protected] 1 points 1 year ago

Lemmy's official conversions is 124 kB. Next time I'm making a meme, I'll see how small I can make the size with webp. Should be better when I'm working from my original and not an already compressed jpeg.

[–] [email protected] 2 points 1 year ago

After reading through more comments in this discussion, maybe I have my answer, at least partially. A lot of people here suggest to use extensions and other ways to convert webp from the web to... PNG.

And then that PNG gets shared further...

Oh gawd if that's why so many pngs are on the net... What a way to take a good idea and completely fuck it up. Now instead of a 2MB jpeg or 0.5MB webp we deal with 10MB pngs 🤦‍♂️
