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.

A rudimentary simulation of the three-body problem
Principia is extremely impressive, they document all their math here: https://github.com/mockingbirdnest/Principia/tree/master/doc...
One interesting detail is that the source code makes extensive use of non-ASCII identifiers, for mathematical symbols and for the names of mathematicians. One of the two primary contributors is also an active contributor to Unicode
- Mods to add after RP-1 express install?

Communication coming out today
KSP2 is still patched conics. Also here's a free n-body mod made by modders, https://github.com/mockingbirdnest/Principia

One week before the release of Kerbal Space Program 2, some kerbonauts are beginning to have doubts
Principia - 𝑛-Body and Extended Body Gravitation for Kerbal Space Program
-
Eli5, Why are planets orbits elliptical and not circular?
But one should just be aware that KSP simplifies by only tracking the strongest source of gravity. This turns all orbits into actual ellipses. But there is a mod called Principia that replaces it with the proper thing, thus allowing for very chaotic (but cool) flight paths using less thrust.
-
Is there a mod in KSP that replaces the Maneuver node tool and makes you do real orbital mechanics?
Principia has n-body
-
Just a friendly PSA that kerbal space program is free on the epic game store this week. Build rockets and figure out how to get to space!
Install Principia and Real Solar System, then try again :P
-
Solar system simulation Newtonian gravitation
Theres a mod that changes that to N-body simulation, it's called Principia

How do I install principia
I'd suggest looking at their readme: https://github.com/mockingbirdnest/Principia
- Will we be able to utilize Lagrange points in KSP2?

Code Search Is Hard
Basic code searching skills seems like something new developers are never explicitly taught, but which is an absolutely crucial skill to build early on.
I guess the knowledge progression I would recommend would look something kind this:
- Learning about Ctrl+F, which works basically everywhere.
- Transitioning to ripgrep https://github.com/BurntSushi/ripgrep - I wouldn't even call this optional, it's truly an incredible and very discoverable tool. Requires keeping a terminal open, but that's a good thing for a newbie!
- Optional, but highly recommended: Learning one of the powerhouse command line editors. Teenage me recommended Emacs; current me recommends vanilla vim, purely because some flavor of it is installed almost everywhere. This is so that you can grep around and edit in the same window.
- In the same vein, moving back from ripgrep and learning about good old fashioned grep, with a few flags rg uses by default: `grep -r` for recursive search, `grep -ri` for case insensitive recursive search, and `grep -ril` for case insensitive recursive "just show me which files this string is found in" search. Some others too, season to taste.
- Finally hitting the wall with what ripgrep can do for you and switching to an actual indexed, dedicated code search tool.

Modern Java/JVM Build Practices
The world has moved on though to opinionated tools, and Rust isn't even the furthest in that direction (That would be Go). The equivalent of those two lines in Cargo.toml would be this example of a basic configuration from the jacoco-maven-plugin: https://www.jacoco.org/jacoco/trunk/doc/examples/build/pom.x... - That's 40 lines in the section to do the "defaults".
Yes, you could add a load of config for files to include/exclude from coverage and so on, but the idea that that's a norm is way more common in Java projects than other languages. Like here's some example Cargo.toml files from complicated Rust projects:
Servo: https://github.com/servo/servo/blob/main/Cargo.toml
rust-gdext: https://github.com/godot-rust/gdext/blob/master/godot-core/C...
ripgrep: https://github.com/BurntSushi/ripgrep/blob/master/Cargo.toml

Ugrep – a more powerful, ultra fast, user-friendly, compatible grep
I'm not clear on why you're seeing the results you are. It could be because your haystack is so small that you're mostly just measuring noise. ripgrep 14 did introduce some optimizations in workloads like this by reducing match overhead, but I don't think it's anything huge in this case. (And I just tried ripgrep 13 on the same commands above and the timings are similar if a tiny bit slower.)

Scrybble is the ReMarkable highlights to Obsidian exporter I have been looking for
🔎🗃️ ripgrep or ugrep (search fast, use regex patterns or fuzzy search, pipe output to bash/zsh shell for further processing V coloring)
- RFC: Add ngram indexing support to ripgrep (2020)
What are some alternatives?
Kerbalism - Hundreds of Kerbals were killed in the making of this mod.
telescope-live-grep-args.nvim - Live grep with args
AA2Unlimited - Modding framework for Artificial Academy 2
fd - A simple, fast and user-friendly alternative to 'find'
SolarSystem - A solar system simulator with Verlet, using OpenGL for displaying.
ugrep - NEW ugrep 5.1: an ultra fast, user-friendly, compatible grep. Ugrep combines the best features of other grep, adds new features, and searches fast. Includes a TUI and adds Google-like search, fuzzy search, hexdumps, searches nested archives (zip, 7z, tar, pax, cpio), compressed files (gz, Z, bz2, lzma, xz, lz4, zstd, brotli), pdfs, docs, and more
