A 37-year-old wanting to learn computer science

Good luck! I’m going through a similar journey. I’m in my late thirties and only started software engineering professionally 5 years ago, without a formal CS degree, but with a hobby-level affinity for computers. It seems like you have an intrinsic interest in the subject. I think this is THE key, because you will grow the most by figuring things out in a play-like fashion, this will solidify your understanding and build intuition.

Looking back what has helped me a lot is being surrounded by more experienced engineers that were good at teaching (those are quite rare I discovered later). Other than that, read a lot of code, write a lot of code, and keep reflecting on what areas to further develop. Be kind to yourself, this space is huge and no one’s is an expert in all of it. Burn out is real, especially when struggling alone for too long. One thing that has helped me as well is to realise everything in software engineering has been made by humans. None of it is actually ‘unknown magic’, just keep digging deeper to find out how the thing you’re struggling with works on a more fundamental level. The LLM age has made this so much easier.

> I really want to learn how to… (misc domain stuff)

From your objectives, I don’t think you want to learn computer science, you want to learn how to be a full stack software developer.

Learning certain aspects of computer science may certainly help you, but it’s by no means a prerequisite - and won’t help you to actually build things.

Learn the things you aim towards by doing and reading domain specific knowledge.

Hey thank you for the time you took to comment and offer advice.

1. I agree. I am still working on the community project which my wife is building - it has started to grow and looks like it has the potential to become a sustainable source of income. I have built the website and automated some stuff for her. I am also honing my skill as a woodworker and toymaker - learning to make wooden toys.

2. I did the HtDP version of the program hosted on the edX platform. I enjoyed the whole program and it was very insightful on how to think about creating larger and complex programs. It also motivated me to read the SICP textbook - I've read a couple of chapters from the book. I also adapted the HtDP program in Hindi to teach village girls here for a local non-profit on how to code.

3. I agree about OSSU. What I don't like about OSSU courses is retention. I did the Programming Languages (A, B and C) course by Dan Grossman a few months back. I enjoyed the course and the exercises - but I am not sure how much of it I retain today. These and the HtDP program has definitely helped me to think what might be happening inside the hood of programs rather than treating them as magical boxes.

4. I think I can keep exploring computers while simultaneously make my living as a woodworker / toymaker. It also helps me balance my faculties of mind and my hands /body. I am not thinking of an end goal at the moment but want to keep exploring and potentially building.
