unsock: shim to automatically change AF_INET sockets to AF_UNIX, etc.
unsock is an LD_PRELOAD-able Linux library that converts AF_INET socket connections to AF_UNIX, AF_VSOCK, AF_TIPC, etc, helping reduce the dependency on TCP/UDP/IP for local communication. It even handles the painful "CONNECT" proxy dance on Firecracker AF_UNIX/AF_VSOCK multiplexing sockets for you.
In plain words
unsock is an LD_PRELOAD library for Linux that automatically converts AF_INET socket connections to alternative socket types like AF_UNIX, AF_VSOCK, and AF_TIPC. It helps applications reduce reliance on TCP/UDP/IP for local communication without code changes. The library also manages the "CONNECT" proxy handshake for Firecracker multiplexing sockets, simplifying configuration in containerized and virtualized environments.

- STSMTP Tunnel – A SOCKS5 proxy disguised as email traffic to bypass DPIJan 2026 · github.com · ▲140
A fast SOCKS5 proxy that tunnels your traffic through what looks like normal SMTP email, bypassing Deep Packet Inspection firewalls. How it works: - Client runs a local SOCKS5 proxy (127.0.0.1:1080) - Traffic is sent to server disguised as SMTP (EHLO, STARTTLS, AUTH) - DPI sees legitimate email session, not a VPN/proxy Features: - One-liner install on any Linux VPS - Multi-user with per-user secrets and IP whitelists - Auto-generated client packages (just double-click to run) - Auto-reconnect on connection loss - Works with any app that supports SOCKS5 Tech: Python/asyncio, TLS…

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…

I made a thing! In 2014, I was holding a stack of iPhones and thought to myself: "Hey, if I had each phone display a playing card, I could click a button and they'd shuffle themselves" I pared that idea all the way down to this: trading cards made of e-ink displays. Right now, each card costs me about $20 each, but with only a bit more scale, I think I can get that down to $10. In doing this project, I learned how to design electronics and circuit boards. I learned Rust and wrote my first driver, I upped my CAD skills, 3D printed, and did my first resin casting. I generated the images on the…
