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.

ELI5 how archiving on computers work
Another fun trick is to compress less often used stuff in RAM memory, because decompressing something like LZ4 or Lizard is still potentially orders of magnitude faster than reading from disk.

APIs in Go with Huma 2.0
I wound up on a different team with pre-existing Python code so temporarily shelved my use of Go for a bit, and we used Sanic (an async Python framework built on top of the excellent uvloop & libuv that also powers Node.js) to build some APIs for live channel management & operations. We hand-wrote our OpenAPI and used it to generate documentation and a CLI, which was an improvement over what was there (or not) before. Other teams used the OpenAPI document to generate SDKs to interact with our service.

Notes: Advanced Node.js Concepts by Stephen Grider
In the source code of the Node.js opensource project, lib folder contains JavaScript code, mostly wrappers over C++ and function definitions. On the contrary, src folder contains C++ implementations of the functions, which pulls dependencies from the V8 project, the libuv project, the zlib project, the llhttp project, and many more - which are all placed at the deps folder.

A complete guide to the Node.js event loop
Libuv, the C library that gives Node.js its asynchronous, non-blocking I/O capability is responsible for managing the thread pool. Node.js gives you the capability of using additional threads for computationally expensive and long-lasting operations to avoid blocking the event loop.

What is Node.js?: A Complete Guide
Node.js is written in C, C++, and JavaScript. The core components of Node.js - the V8 engine and the libuv library - are written in C++ and C, respectively, since these languages provide low-level access to system resources, making them well-suited for building high-performance and efficient applications. JavaScript is mainly used to write the application logic.

Node v20.3.0 (Current) upgrade to libuv 1.45.0, including SIGNIFICANT performance improvements to file system operations on Linux

Node.js – v20.3.0
Notably upgrades to libuv 1.45 which has io_uring support. Faster file system access! Awhh yeah, it's on.
Remarkable what a mild & unintrusive PR adding io_uring was. https://github.com/libuv/libuv/pull/3952

Using Parallel Processing in Node.js and its Limitations
Well, the single-threaded nature ultimately leads to its biggest downfall. Node.js utilizes a synchronous event loop engineered using Libuv that takes in code from the call stack and executes it.
What are some alternatives?
ZLib - A massively spiffy yet delicately unobtrusive compression library.
libevent - Event notification library
python-zstandard - Python bindings to the Zstandard (zstd) compression library
Boost.Asio - Asio C++ Library
lzbench - lzbench is an in-memory benchmark of open-source LZ77/LZSS/LZMA compressors
libev - Full-featured high-performance event loop loosely modelled after libevent
c-blosc - A blocking, shuffling and loss-less compression library that can be faster than `memcpy()`.
tokio-uring - An io_uring backed runtime for Rust
qemu
uvw - Header-only, event based, tiny and easy to use libuv wrapper in modern C++ - now available as also shared/static library!
sndfilter - Algorithms for sound filters, like reverb, dynamic range compression, lowpass, highpass, notch, etc
