I'm second-career web developer (writing mostly Ruby) since 2022, meaning I didn't get a computer science degree. So this list is me catching up.
My "Learn Ruby" list slightly overlaps with the material in this list, namely in the sections "Foundations" and "Beyond Ruby".

- Hardware systems
- Operating systems
- Concurrency
- Database internals
- Compilers
- Math / logic

- HTTP:
- Beej's Guide to Network Programming
- Experiment with CDNs or reverse proxies (e.g. Nginx, Varnish, HAProxy, Cloudflare) to understand caching, TLS termination, load balancing, and security filtering (rate limiting, WAF, etc.).
