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.

OpenWrt 23.05
It's work in progress: https://github.com/Mbed-TLS/mbedtls/blob/development/docs/ar...
Newer version have okay-ish support, I'd guess the next OpenWRT release will have it again.
-
How can I disable the close_notify message?
It's related to this Mbed-TLS issue
-
DIY Physical Backed Tokens (EIP-5791) with ESP32 and BLE
i've used the entropy generator from MbedTLS which uses multiple sources of randomness, and seeding it additionally with the chip's mac address and the free heap size at time of creation. it would take a lot to recreate all that "noise" consistently, but i'm open to suggestions on how to make it more secure
-
Help libraries won’t work on the IDE for esp32
However on the github page and assuming I found the right source - and this is a HUGE ASSUMPTION - there is a section on porting the library to other platforms.

redbean: a single-file actually portable web server with Lua, HTTPS and SQLite
Rebean is a single executable written in ANSI C that embeds Lua 5.4, MbedTLS and SQLite. The crazy thing about this is that it is a C binary that runs on six operating systems without any cross compiling thanks to leveraging Justine Tunney's cosmopolitan.
-
Install mbedTLS on Linux
it looks like the commands are all built under https://github.com/Mbed-TLS/mbedtls/tree/development/programs and the arch mbedtls package does some extra work to rename them and copy them into /usr/local/bin: https://github.com/archlinux/svntogit-community/blob/packages/mbedtls/trunk/PKGBUILD#L55
-
Elliptic Curve Cryptography Explained
If you want to see a real implemention of arbitrary sized integer math, mbedTLS is a great example:
https://github.com/ARMmbed/mbedtls/blob/development/library/...
All of the ECC code in that library relies on this code, which can be accelerated by dedicated hardware.

mbed TLS - Another crypto implementation. Apache-2.0
-
WireGuard implementation for LwIP stack
Definitely, FreeRTOS + LwIP + Mbed TLS is a fairly common combo these days, and Mbed TLS has hardware acceleration where possible.

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
x8 apparently https://github.com/libuv/libuv/pull/3952
-
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?
OpenSSL - TLS/SSL and crypto library
libevent - Event notification library
wolfssl - The wolfSSL library is a small, fast, portable implementation of TLS/SSL for embedded devices to the cloud. wolfSSL supports up to TLS 1.3!
Boost.Asio - Asio C++ Library
libsodium - A modern, portable, easy to use crypto library.
libev - Full-featured high-performance event loop loosely modelled after libevent
GnuTLS - GnuTLS
tokio-uring - An io_uring backed runtime for Rust
LibTomCrypt - LibTomCrypt is a fairly comprehensive, modular and portable cryptographic toolkit that provides developers with a vast array of well known published block ciphers, one-way hash functions, chaining modes, pseudo-random number generators, public key cryptography and a plethora of other routines.
uvw - Header-only, event based, tiny and easy to use libuv wrapper in modern C++ - now available as also shared/static library!
LibreSSL - LibreSSL Portable itself. This includes the build scaffold and compatibility layer that builds portable LibreSSL from the OpenBSD source code. Pull requests or patches sent to [email protected] are welcome.
