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.

Hello, PNG!
Pull requests welcome. :D

Are IDAT chunks in PNG encoded individually?
There are multiple github issues on the subject where we work on future editions of the PNG spec. (3rd Edition coming soon!)

Google Chrome Is Already Preparing To Deprecate JPEG-XL (~3x smaller than JPEG, HDR, lossless, alpha, progressive, recompression, animations)
Especially enticing as the PNG file format does allow for additional compression/filter methods and new ones could be added to a PNG 2.0 standard. A small wishlist discussion about that at the W3C's PNG specification Github.

QOI – The “Quite OK Image Format” for fast, lossless image compression
> But its not like any reader ever supports it fully, hell most readers dont support showing the other images in a png file.
Do you mean APNG? In all fairness, that is not even in the specification although there is discussion to add it. https://github.com/w3c/PNG-spec/issues/26
The one that was specified was MNG but it was a different format and practically no one used it since it was not parsable as a PNG.

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.

Open-sourcing a commercial product
We have been faced with the same question and decided to open-source pretty much all of our product (https://github.com/toitlang/toit).

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.

Toit – A Language Designed for Microcontrollers
We use it for some of our tools, so it's possible (and works nicely). Our LSP server was initially written in Toit: https://github.com/toitlang/toit/tree/master/tools/lsp/serve...
