The dithered images are fun, but I thought PNG is optimized for large continuous areas of an identical color (or pattern?). Is JPG or WebP not better?

- worldofmatthew 4y agoI sent them a email about that (to their comments email) and never got a response.
- kragen 4y agoThey're hypersensitive to suggestions that they might be wrong about something.
- sslayer 4y agoIs this a whoosh situation where the low tech comes into play?
- kragen 4y agoI don't know what you mean.
- asymmetric 4y agoDo you have context for this?
- giantrobot 4y agoIn previous discussions about the site/posts on the site on HN I remember the site owner getting very butthurt in threads over criticism. I don't have specific links however. Just anecdata.
- mdp2021 4y agoYou surprised? They serve (in the "about" page) one big page for everything, with everything (80% of it user comments, I noted nearby), and their motto is «radically reduce the energy use associated with accessing our content»!
- kragen 4y agoWell, when a guy is hypersensitive and defensive about being wrong about things, he tends to remain wrong about them.
- ReactiveJelly 4y agoI tried to do a comparison once. It was approximate, because I didn't have the original images (Or I only had one), but IMO JPEG looks better per pound of bits than dithering. At the same bitrate as their dithered images, it looks a bit crummy, but you can still pick up details that the dithering loses. They won't admit it's for the aesthetic. If dithering looked as good bit-for-bit as JPEG, independent of aesthetic, nobody would have invented or adopted JPEG.
- worldofmatthew 4y agoThey would have to admit to transmitting more data (thus using more carbon) for aesthetics. That would undermine their blog and make some of their posts look very hypocritical.
- klez 4y agoAm I reading it wrong that they're not doing this for file size but for processing power reasons? I'd be curious (really, not being snarky) if you tested for that as well. EDIT: nope, I'm wrong, they say they're doing it for bandwidth.
- MisterTea 4y ago> WebP No to webp as it's a still vp8 video frame meaning an image codec is burdened with a huge video codec dependency.
- mdp2021 4y agoHave you not tried? A 4-cols PNG can be halfish a JPEG. Of course, a ~10% quality JPEG can be one fifthish of the original, and present more apparent information than the PNG - but it will look dirty.
