What are some less popular but well-made crates you'd like others to know about?
Tetra 2D game library. It's very easy to pick up and use. I'd like to bring more attention to it. https://tetra.seventeencups.net/

Is there any 2d only game library with high stuff. I think it would be light-er than bevy and won't crash my PC. Like pygame for python for an instance, supporting collision and stuff in Rust!!!!?
I've also used GGEZ and heard good things about Tetra.

Looking for an open-source project to join part-time
and speaking of game engines, tetra is a really nice one. it's kind of the opposite of bevy - it doesn't tell you how to architect your game, it just gives you some basic graphics/input/audio tools, and you're on your way.

Jpegli: A New JPEG Coding Library
> all decoders will render the same pixels
Not true. Even just within libjpeg, there are three different IDCT implementations (jidctflt.c, jidctfst.c, jidctint.c) and they produce different pixels (it's a classic speed vs quality trade-off). It's spec-compliant to choose any of those.
A few years ago, in libjpeg-turbo, they changed the smoothing kernel used for decoding (incomplete) progressive JPEGs, from a 3x3 window to 5x5. This meant the decoder produced different pixels, but again, that's still valid:

My personal C coding style as of late 2023
Last vestiges of this fact AFAIK were libjpeg, which had a macro NEED_SHORT_EXTERNAL_NAMES that shortens all public identifiers to have unique 6-letter-long prefixes. Libjpeg-turbo nowadays has removed them though [1].

Why there may never be a libjpeg-turbo 3.1
While I think the move to safer code through Rust and other alternatives is a nice breath of fresh air, I doubt you can get these kinds of optimization without using unsafe code in Rust. These optimized implementations often require some kind of safety-bypassing memory modifications to work as efficiently ad they do.
There's a reason https://github.com/libjpeg-turbo/libjpeg-turbo/tree/main/sim... is filled with assembly files with conditional loading.

Learn x86-64 assembly by writing a GUI from scratch
Sure. You'll see it very often in codec implementations. From rav1e, a fast AV1 encoder mostly written in Rust: https://github.com/xiph/rav1e/tree/master/src/x86
Large portions of the algorithm have been translated into assembly for ARM and x86. Shaving even a couple percent off something like motion compensation search will add up to meaningful gains.

Announcing zune-jpeg: Rust's fastest JPEG decoder
zune-jpeg is 1.5x to 2x faster than jpeg-decoder and is on par with libjpeg-turbo.

JDK 21 - Image Performance Improvements
This is interesting from the standpoint of how new JVM features can be used to improve performance (what I presume the article's main purpose to have been), but the image processing improvement itself isn't head-turning. Also, we've found that libjpeg-turbo (https://libjpeg-turbo.org/) is ~5x (IIRC, can re-run my JMH benchmark if anyone wants me to) as fast for decoding JPEGs as ImageIO, so we wouldn't even benefit from this change in 21 much.

How to go about implementing file encoding [Question]
For all but the simplest formats (basically BMP), the difficulty of implementing encoding/decoding from scratch is significant - well beyond a beginner's ability, and challenging/time-consuming even for senior developers. So, libraries are used in practice - e.g. libpng and libjpeg-turbo.
