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.

When Zig Outshines Rust – Memory Efficient Enum Arrays
As somebody who has written the same gameboy emulator in C++, Rust, and Zig (as well as C, Go, Nim, PHP, and Python) - I have yet to find a place where language affected emulation correctness.
Gameboy audio is kind of a pain in the ass (at least compared to CPU, which is fairly easy, and GPU, which is easy to get "good enough” if you don’t care about things like palette colours being swapped mid-scanline) - and some languages take more or less code to do the same thing (eg languages which allow one block of memory to be interpreted in several different ways concurrently will make the “interpret audio RAM as a bunch of registers” code much shorter with less copying) - but in my case at least, each one of my implementations actually has the same audio distortions, presumably because I’m misreading some part of the hardware spec :P

(Also yes, the zig version is currently failing because every time I look at it the build system has had breaking changes...)

Ask HN: Why did Nim not catch-on like wild fire as Rust did?
Niceness is subjective, but Nim is just as valid an addition to that group. Nim compiles to C and has had an --os=standalone mode for like 10 years from its git history, and as mentioned else-thread (https://news.ycombinator.com/item?id=36506087) can be used for Linux kernel modules. Multiple people have written "stub OSes" in it (https://github.com/dom96/nimkernel & further along https://github.com/khaledh/axiom).
While it can use clang as a backend, Nim does not rely upon LLVM support like Zig or Rust (pre-gcc-rust working). Use on embedded devices is fairly popular: https://forum.nim-lang.org/search?q=embedded (or web search).
Latency-wise, for a time, video game programming was a perceived "adoption niche" or maybe "hook" for Nim and games often have stringent frame rendering deadlines. If you are interested in video games, you might appreciate https://github.com/shish/rosettaboy which covers all but Ada in your list with Nim being fastest (on one CPU/version/compiler/etc). Note, however, that cross-PL comparisons are often done by those with much "porting energy" but limited familiarity with any but a few of the PLs. A better way to view it is that "Nim responds well to optimization effort" (like C/Ada/C++/Rust/Zig).

Ask HN: What have you created that deserves a second chance on HN?
https://github.com/shish/rosettaboy
The same gameboy emulator rewritten in C++, Go, Nim, PHP, Cython, Python, Rust, and Zig (and WIP typescript); mostly to teach myself the languages and to compare and contrast their idioms.
Also, when taken with a very large grain of salt, usable as a language benchmark (As with all benchmarks, there are lots of caveats - but as far as I’m aware this is unique in being “the same code in multiple languages” and “several thousand lines of code”):
$ ./utils/bench.py
- Zig 0.10.0 Release Notes
- Python 3.11 is much faster than 3.8

Writing a Game Boy Emulator in OCaml
Looks very polished, but major disappointment that it's not showcasing OCaml as part of RosettaBoy (https://github.com/shish/rosettaboy)

Which programming language or compiler is faster
I’m working on it :) https://github.com/shish/rosettaboy
(Ok it’s 5-10k lines rather than a million, but it’s non-trivial enough that the differences between languages are noticable)

No JS, and easy to self host. It’s a place to put your dotfiles. It comes with a ClI loosely based on git for editing, versioning, pushing, and pulling.

Ask HN: What's Your Side Project?
It seems like Covid left a lot of restaurants scrambling for contactless ordering solutions. They can be nice, but I find it annoying when I have to use my phone to look at a menu or to make an order. How does your system work?
My side project is https://dotfilehub.com
It’s a bare bones version control system for single files + a web interface.

Ask HN: What (side-)project are you working on?
Dotfilehub: https://dotfilehub.com
I've always found various solutions that use git for sharing configuration files cumbersome. I set out to make my own simple version control system, and a lightweight web application where I can browse and edit them remotely. The main idea is that paths are aliased to simple names, so I can say `dotfile pull i3` and it will install https://dotfilehub.com/knoebber/i3 to ~/.config/i3/config
Overall the project is stable and I use it daily for all sorts of miscellaneous files.
