Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

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: Don’t 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

Next.js and Bunny CDN: Complete Guide to Image Uploading with Server Actions
Last thing left is to use our new upload function in our server action. Since I like to upload images in single format and have some more control over them, I will additionally use sharp library. For file name, I'll generate some random string using nanoid:

Optimizing Image Display with Blur Placeholder and Lazyload
blur is a technique to blur images while reducing the file size surprisingly. blur works by enlarging the pixels of the image, which reduces the details of the image, and the number of colors also decreases, thus saving storage space. Sharp is a popular image processing library in Node.js, and it supports the blur function. After going through the blur function, the image size at this point is only a few KB, which is reasonable for an image placeholder in the article.

JavaScript Gom Jabbar
ESLint does an amazing job in detecting floating promises. I've not had it miss one, ever. When adding this to a project, I've discovered multiple accidental bugs due to a missing "await" keyword--bugs that were extremely subtle and intermittent in many cases.
The only thing it can't do is determine that you actually did handle the promise later. Which is fine. It's a LINTING RULE, and false positives are the name of the game.
What's BAD is when you accidentally miss handling a promise at all. It's an invisible error without the linting rule.
Your other comments...don't even make sense. You're going to build a Lanczos filter by hand? Or you're only going to ... compile ImageMagick to WebAssembly?!, ... an implementation which is tremendously slower (nearly unusably so for large images) than that of Sharp:
https://www.npmjs.com/package/sharp
... which is simply an import away?
No, what you're doing is called "motivated reasoning." You've concluded that Deno is the best, and you're reinterpreting all of my complaints in convoluted ways to support your predetermined conclusion.
Standard fanboy behavior. Or troll behavior. I cite Poe's Law as why it's impossible to tell the difference.
