Professionally. I’ve been teaching myself Web Dev for the past 4 years and have actually worked at a small start up briefly, but want to work at a small/medium size company at some point.

I can’t afford to go back to school, but am familiar with the classic CS curriculum, in part thanks to the resources listed on that website you referenced. Thank you for that.

It’s just taking me a long time as while I have a college degree, I have never had a strong background in mathematics, let alone the discrete mathematics generally required by most robust CS curriculum.

That said, I have a great support structure, with many mentors and a solid local and online community. I’ve even hung out with a few Linux kernel devs, who have graciously given me various pieces of advice on how to proceed learning the basics.

This TCP/IP book is sort of a detour, as I don’t see myself utilizing the concepts directly (save for a bit of packet analysis), but I’ve noticed web developers, at least at the Jr level, tend to only have a surface level knowledge of how HTTP fits into the broader TCP/IP model, and I’d rather that not be the case for myself.

Thanks again for that resource. I’ve yet to dive deep into a lot of the books on that site, but it’s been in my bookmarks for a while now, and I definitely will be getting around to inspecting them more deeply in the near future.
