What would you learn if you would have three to six months free time?

From my past 5 military deployments it’s not what I would learn. It’s what I would write. On my last deployment I created a new way to perform test automation in the browser that is dramatically faster and more simple than the big tools. I also refined a tiered security model for decentralization. On the deployment prior to that one I made some refinements to my diff application and created a data model for stacked language representation (a uniform less powerful but more scalable alternative to abstract syntax trees)

Go to Japan and take an intensive japanese course. Yamasa Institute in Okazaki is a great school.

It's hard to justify spending lots of time learning fundamentals while working on real projects. The kinds of things taught in college.

So, assuming one is a programmer, whatever one's weakest areas are: math, algorithms, assembly, operating systems (Linux), networking, distributed systems, electronics, machine learning, etc.

Or if one is already really solid in all fundamentals, and lacking more practical expertise, then a modern popular programming language like TS/JS, Go, Rust.

Or if you just want to learn for fun, I'd read recommend reading a lot of biographies of historical figures. And/or learning a foreign language.

And of course, learning how to cook your own food, exercise your body, and sleep well are probably more important than anything else you could possibly do for yourself.

Algebra, the real one, with groups and rings and so forth

I would prepare for a long distance trail or triathlon like a pro - with proper rest etc - you could learn a lot about yourself and your body.

Spending holidays entirely studying security stuffs to sharpen my skills, so a lot more of that. Kernel mode exploitation, mobile forensics and exploitation (beyond msf+social engineering). If i have more time learn ada, erlang and ocaml and then write offensive tools for the sake of it (and to evade detection). Too much shit on my list.

Vulnerability analysis and subsequent exploitation development. I would obviously need way more time than that to be good at it but I've always found the topic interesting.

This massive resurgence in generative AI has me interested in the AI space all over again.

Going to spend the next 3-6 months just learning everything I can about it.

Another language in intensive in-person classes.

Difficult and unrealistic probably, but I would spend this time to immerse myself in language learning (one of ACEFRS) .
