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

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 - đť‘›-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?

Understanding SQL vs. NoSQL Databases: A Beginner's Guide
SQL (Structured Query Language) databases are relational databases. They organize data into tables with rows and columns, and they use SQL for querying and managing data. Examples include MySQL, PostgreSQL, and SQLite.

I Deployed My Own Cute Lil’ Private Internet (a.k.a. VPC)
Each app’s front end is built with Qwik and uses Tailwind for styling. The server-side is powered by Qwik City (Qwik’s official meta-framework) and runs on Node.js hosted on a shared Linode VPS. The apps also use PM2 for process management and Caddy as a reverse proxy and SSL provisioner. The data is stored in a PostgreSQL database that also runs on a shared Linode VPS. The apps interact with the database using Drizzle, an Object-Relational Mapper (ORM) for JavaScript. The entire infrastructure for both apps is managed with Terraform using the Terraform Linode provider, which was new to me, but made provisioning and destroying infrastructure really fast and easy (once I learned how it all worked).

How to dump and restore a Postgres DB with new table ownership
I've used MySQL for years. But recently, I found myself working PostgreSQL and simple things like dumping and restoring a database are different enough that I decided to document the process. It's straightforward enough once I knew how.

Test Driving a Rails API - Part One
A running Rails application needs a database to connect to. You may already have your database of choice installed, but if not, I recommend PostgreSQL, or Postgres for short. On a Mac, probably the easiest way to install it is with Posrgres.app. Another option, the one I prefer, is to use Homebrew. With Homebrew installed, this command will install PostgreSQL version 16 along with libpq:

How to choose the right type of database
PostgreSQL: Offers a robust feature set and strong compliance with SQL standards, making it suitable for a wide range of applications, from simple to complex, particularly where data integrity and extensibility are key.

NoSQL Postgres: Add MongoDB compatibility to your Supabase projects with FerretDB
FerretDB is an open source document database that adds MongoDB compatibility to other database backends, such as Postgres and SQLite. By using FerretDB, developers can access familiar MongoDB features and tools using the same syntax and commands for many of their use cases.

Preventing SQL injection attacks in Node.js
To better understand how SQL injection works, let's quickly create a vulnerable app using Node.js, Express, and a PostgreSQL database. The application takes user input from a form, constructs a SQL query, and executes it against the database to fetch some data.
