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.

rust the compiler, hell no.
But there is an llvm-mos project to generate 6502 code and that can be used to cross compile rust code.

It was possible thanks to great https://llvm-mos.org/wiki/Welcome project (it adds 6502 target to LLVM). Adding 6502 support to rust was easy part :] https://github.com/mrk-its/rust-mos

LLVM-MOS 6502 Back end [pdf]
This is a super fun project to play around with. I'm currently trying to build a C64 sprite multiplexer in mostly straight C++ using LLVM-MOS and while it's definitely not going to be the most optimized multiplexer out there, I'm finding it most adequate performance-wise.
Whereas it's probably a long way away from being able to use this for democoding due to the mostly cycle-accurate nature of the effects, for creating homebrew games and utilities this is really quite suitable: write high-level logic and sprinkle in some inline assembly here and there for the really performance critical parts.
The code that is being generated is already quite good and (on first glance) looks better than what's coming out of cc65, for instance.
There's also rust-mos which uses LLVM-MOS to compile Rust code. It unfortunately still has some issues (e.g. [1]) but that is looking really promising as well.
Kudos to all involved :)

The Rise of Rust, the βViralβ Secure Programming Language Thatβs Taking Over Tech
The MEGA 65 doesn't appear to have shipped yet. The best data I could find is the MEGA 65 is based on a "GS4510". The "GS4510" is compatible with a "4502", which in turn is compatible with the 65CE02. The 65CE02 uses a different manufacturing process but the same ISA as the 6502, which is supported by rust-mos and lvm-mos](https://github.com/llvm-mos/llvm-mos).

Can you write for the Commodore 64 in Rust? Why yes, yes you can!
Using llvm-mos, rust-mos, a lot of time compiling compilers and support from Mariusz (the rust-mos author), I was finally able to program like it was 1982...

This fork is handy for that. Itβs fun to play with, but you need to do a decent amount yourself to get it set up.

Can Rust do every low level stuff C/C++ do?
Thanks to llvm-mos project there is also working rust fork for MOS-6502: https://github.com/mrk-its/rust-mos/tree/mos_target, so you can target 8-bit atari and c64

[2023 Day 5 Part 2] Haskell libraries really shine here
I didn't realize Haskell had that. I wrote a similar Scala library for 2022 Day 15 that's basically the encapsulated equivalent of a [Range a], but I really like the API of Haskell's library. Especially Haskell always handles infinite sequences well.

[2022 All Days]
Here's mine. Most of it I wrote in prior years, but refined this year. To account for problem-specific details, the functions are very generic and higher-order. It has a handful of well-known algorithms like A* and Floyd-Warshall, some handy data structures like circular buffers and intervals, and some type classes that are useful for parsing puzzle input.

I wrote an immutable A* in Scala a few years ago. It's not too bad if you have immutable hash maps and an immutable priority queue. Comes in handy for a lot of puzzles.

[2022 day 4] My experience in a nutshell
Last year I made myself an input parsing library that was really nice for this problem. I just create a Pair class with 4 number members, then ask for a List[Pair] and it knows what to do. My solution.

Best immutable priority queue for scala
I implemented my own using a pairing heap. It sped up my immutable A* considerably, but I was just using minBy on a List before that. Inserts are amortized O(1) and delete-mins are O(log n).

What is the best way to read a text file of your input in your language of choice?
This year I'm creating a Scala library to make it easier. I specify a type like List[Int] and it summons the correct type classes to parse it into that format for me.
What are some alternatives?
