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.

Radicle: Open-Source, Peer-to-Peer, GitHub Alternative
Everything that is replicated on the network is stored as a Git object, using the libgit2[0] library. This library uses hardened SHA-1 internally, which is called sha1dc (for "detect collision").

Speedbump – a TCP proxy to simulate variable network latency
This is delightful and I can't wait to try it out. Right now, the libgit2 project (https://github.com/libgit2/libgit2) has a custom HTTP git server wrapper that will throttle the responses down to a very slow rate. It's fun watching a `git clone` running over 2400 baud modem speeds, but it's actually been incredibly helpful for testing timeouts, odd buffering problems, and other things that crop up in weird network environments.
I'd love to jettison our hacky custom code and use something off-the-shelf instead.

GitKraken Client Is Migrating from Libgit2 to the Git Executable
I've built a UI on top of libgit2 and I wish that this blog post expanded on which new features are missing (sparse checkout?).
To quote: "The migration to Git Executable will allow us to resolve long-standing issues with GitKraken Client, such as poor LFS performance, SSH configuration support and many other features/performance improvements."
I agree on LFS performance on Windows. SSH config support is a pain due to libssh2 but openssh support is on the way (https://github.com/libgit2/libgit2/pull/6617).
There are many cons to using the Git executable itself (parsing output, error reporting, version handling). Seems to me that there's more to this?

Mold 2.0.0
I'm curious about the license change? This is an executable is it not? Invoking it as a separate process does not require you make the software calling it GPL so switching to MIT should have no affect in the common case.
If the authors really wanted a more permissive license, then instead of relicensing from AGPL to MIT they should have gone AGPL with linking exception. An example of a project that does this is libgit2 [1]. This licensing is more permissive but still permits the author to sell commercial licenses to those making closed-source code changes.

I'm feeling lazy today but want a better excuse than "working on documention" for the morning standup.
Using libxlsxwriter and libgit, it's straightforward -- just putting the equivalent of git shortlog and lines added and removed into a line of cells.

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?
pygit2 - Python bindings for libgit2
libevent - Event notification library
elfshaker - elfshaker stores binary objects efficiently
Boost.Asio - Asio C++ Library
git-branchless - High-velocity, monorepo-scale workflow for Git
libev - Full-featured high-performance event loop loosely modelled after libevent
horde - Horde is a distributed Supervisor and Registry backed by DeltaCrdt
tokio-uring - An io_uring backed runtime for Rust
git-date - Bindings onto the date parsing code from Git
uvw - Header-only, event based, tiny and easy to use libuv wrapper in modern C++ - now available as also shared/static library!
