It provides a simple macro-based API to intercept method calls, execute custom native logic, and optionally call the original Java implementation — all without modifying the Java side.

pedix is a lightweight, clean x86/x64 disassembler written in pure C. It decodes and displays x86 machine code instructions with clear output, making it useful for learning, reverse engineering, and low-level systems development.
I have written a vpn protocol called Hermes that does two things:
This protocol is written fully from scratch in Ruby programming language with the help of WinTun driver for Windows and built-in tun/tap support inside a linux kernel.
Client uses websockets as a transport protocol, but the most important part is that it uses chromium browser as a broker between the server.
The browser is used to simulate the tls fingerprint in order to avoid detection. Similar technique is used in uTLS (https://www.twine.net/signin
