I built an HTTP/2 server in C++ to learn the protocol and language
I wanted to learn more about the HTTP/2 protocol but also deep dive into modern C++ development. I'm currently using it to host my personal web site - https://www.roberthargreaves.com. I've also blogged a bit about the development process, hosting options and steps I took to harden the application against attack - https://blog.roberthargreaves.com/2026/01/03/building-hostin... It's by no means a complete implementation of HTTP/2, but I think I've achieved the main aims I was hoping to achieve with it! I would love some feedback though from…
In plain words
This is a custom HTTP/2 server built in C++ as a learning project for both the protocol and modern C++ development. The creator uses it to host their personal website and has documented the development process, hosting decisions, and security hardening measures in blog posts. While not a complete HTTP/2 implementation, it achieves the builder's core learning objectives and is actively serving production traffic.

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:…

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
