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.

png crate gets an ultrafast compression mode, up to 4x faster decompression
When the QOI format was first announced it wasn't clear that was even possible while keeping PNG format compatibility. But the fpng and fpnge C/C++ libraries showed it was, and today you can take advantage of those advances in a general purpose PNG library in Rust!

Hello, PNG
CRC is a table and 5 lines of code. That's trivial.
>zlib is 23k lines
It's not needed to make a PNG reader/writer. zlib is massive overkill for only making a PNG reader or writer. Here's a tiny deflate/inflate code [2] under 1k lines (and could be much smaller if needed).
stb[0] has single headers of ~7k lines total including all of the formats PNG, JPG, BMP,. PSD, GIF, HDR, and PIC. Here's [1] a 3k lines single file PNG version with tons if #ifdefs for all sorts of platforms. Removing those and I'd not be surprised if you could not do it in ~1k lines (which I'd consider quite simple compared to most of todays' media formats).
>Of course they're not common formats so you're stuck with complex formats like PNG
BMP is super common and easy to use anywhere.
I use flat image files all the time for quick and dirty stuff. They quickly saturate disk speeds and networking speeds (say recording a few decent speed cameras), and I've found PNG compression to alleviate those saturate CPU speeds (some libs are super slow, some are vastly faster). I've many times made custom compression formats to balance these for high performance tools when neither things like BMPs or things like PNG would suffice.

This was actually considered, and other libraries do ignore checksums, or at least have options to:

QOI – The Quite OK Image Format
In the other direction, you can target a subset of PNG to get less optimized images but with QOI-like encode and decode speed: https://github.com/richgel999/fpng

ReShade 5.0 Released!
On specific operations like screenshots for example the new version is WAY faster though. We were using stb_image_write.h but switched to fpng which promised 12-19x faster compression at smaller sizes. That and the fact that screenshot saving have now been given it's own thread so it now longer causes a small stutter like when it was on the main thread, means that screenshot are now near instantaneous.

QOI – The “Quite OK Image Format” for fast, lossless image compression
I think QOI inspired the creation of https://github.com/richgel999/fpng which creates standard PNGs and compares itself directly to QOI.

Losslessly compresses RGB and RGBA images to a similar size of PNG, while offering a 20x-50x speedup in compression and 3x-4x speedup in decompression
BTW, today I found this fpng-fast PNG writer. There is a comparison with QOI in the readme.

Hey all! ESP32 beginner here, looking for a little advice
It uses toit, a high-level language, and is thus quite easy to learn. At the same time it's an order of magnitude faster than micropython.

Rust on Espressif chips – 2023 Roadmap
I also really like MicroPython! Having said that, I have been working on an alternative to it for a number of years now -- primarily to provide a more robust and performant high-level alternative to C and Rust on the ESP32-family of chips:
https://github.com/toitlang/toit
I'd love to pick your brain and fully understand your experience with MicroPython. I've been doing programming languages for a number of years now, and I find that it is incredibly useful to understand what developers appreciate (and dislike) about the available stacks.

ESP32 Buyer’s Guide: Different Chips, Firmware, Sensors
Thank you for the mention!
I have been working on the Toit language for the ESP32 for a number of years now -- and it has been an enjoyable challenge to build an open source stack capable of supporting live reloading on a micro-controller that can run for years on batteries.
