Ask HN: Stuffs to reward myself in my journey of self learning CompSci x DevOps?

I've plannned for an extensive CompSci x sysadmin x backend engineer curriculum for myself after visiting lots of roadmap sites like roadmap.sh/devops etc. I've planned that I'd gift myself something that makes me happy. It could be: - the ultimate gift to myself will be a travel - the small gifts on the way could be any learning materials(books/courses) that help me to further my knowledge in that field. This is quite ambitious and not in particular order and isn't expected to finish ever. It's a continuous process. I've given my short background at the end (if you're interested) # Operating System completed Say, I complete learning the fundamentals of Operating System(CS course), then I'll be gifting myself a book on vim/vi editor # DBMS completed I'd gift myself "understanding the linux kernel" book. # Java completed ? # Data Structures completed ? # Algo completed "Cracking the coding interview" book. # Docker completed ? # Kubernetes completed "postgresql 16 administration cookbook" book. # Linux LVM completed "data science at the command line" book # Linux Bash script completed "cyber ops with bash" book # Node.js completed OSCP course buy(not the certification just learning materials from one site I know of) # performance testing completed ? # DBMS security completed ? # network security completed ? # Linux course completed Ashghar Ghori RHCSA book as gift # Git completed ? # Computer Networks completed for the second time ? My background - I've been doing stuffs on linux since years and employed as a production support associate. - I'm selfhosting various stuffs on Linux server(before you tell me to skip all these learnings and self host). - I'm quite active in various popular linux forums, asking questions mostly. And helping if I find something very obvious. - I've around 50 virtual machines in my current home laptop. I definitely won't just read books and don't apply anything(before you tell me to not do so).
