I spent 6 months building a C debugger as a 17-year-old

Hey HN my name is Thassilo, I'm a student and passionate programmer from Germany. I want to showcase Spray, a small C debugger I've been working on for a few months now. Spray has a very simple and approachable interface. Its feature set is limited at this point, but it's already enough to tackle some basic problems. I stared to work on Spray because I was curious about how debuggers work. I am also trying to design Spray in such a way that it's easy to grasp and has a small mental overhead.

In plain words

Spray is a C debugger with a simple, approachable interface designed for basic debugging tasks. Built by a German student over several months, it prioritizes ease of use and minimal cognitive overhead for developers learning how debuggers work. The tool has limited features but provides enough functionality to address common debugging problems. It is available on GitHub for those interested in exploring how debugging tools operate.

I'd love to get your feedback on Spray. Email: d4kd (at) proton (dot) me PS: I'm generally interested compilers and language tool chains, and I'm looking for similar-minded people to work and collaborate with. I have a few similar projects on my GitHub: https://github.com/d4ckard?tab=repositories. If you find Spray interesting, you might enjoy playing around with them too.

  • 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:…
