FSF Slams Google over Dropping JPEG-XL in Chrome
The article is about avif not webp. Note the editors for the AOM avif specification don't even include Google https://aomediacodec.github.io/av1-avif/

Whistleblowers Take Note: Donβt Trust Cropping Tools
This reminds me of something similar from the guy who implemented AVIF in Firefox. He gives a talk about the implementation [1] where he talks about the CLAP privacy problem. Basically the spec adds a field that allows for cropping of the image, but the binary file would still contain the original. This would lead users to believe some image data was deleted when it really wasn't. I always thought he spent a lot of time and effort on this for little gain, but now I'm starting to think it was worth his effort.

AVIF images encoded with yuv422 appear black on iOS 16 / MacOS Ventura
So actually the same images I linked above are in the AOMediaCodec repo as well, under Link-U: https://github.com/AOMediaCodec/av1-avif/tree/master/testFiles/Link-U And I see the same issue with the yuv422 images there as well. I'm guessing Apple's AVIF implementation must be incomplete?

What is AVIF?
Created by Alliance for Open Media and worked on by Netflix, Microsoft, and Google developers, AVIF is open source - you can even weigh in on image processing and spec issues.

How can HDR AVIF stills be created?
I've been trying to find a way edit 14bit RAW files (.ARW) to an HDR capable format (HEIF/AVIF). In the process I found out there's an official AVIF encoder (1) by AOM that seems like it should be capable of creating HDR PQ stills.

Question: Multiscale AVIF performance?
AVIF can do something that resembles hierarchical JPEG and that could be useful for progressive decoding: you can have multiple layers/scales, where e.g. first a 1:4 image is encoded, then residuals to get to 1:2, then residuals to get to 1:1. Examples of this were recently added to the AVIF spec: https://github.com/AOMediaCodec/av1-avif/pull/134

go-LinkSaver
I use Lepton as my GitHub Gists manager. You actually don't need lepton for this but I like it.
- Does anyone know a better a way to manage a LOT of Github gists?

Do you guys use GitHub as a place to store basic scratchpad and one-liners?
For one liners and small snippets I uses a great open source app call Lepton which is a snippet manager that saves to your github accounts gists. They ate stored private by default, so its perfect to securely save and version small bits and pieces that don't fit into their own repository
