For example, on my "C and C++ page", I actually used my note regarding "nm --demangle" which I used to help figure out a linker issue in some C++ code that I have to build in my current job. I haven't done much with C/C++ in years, so this was helpful to trigger long forgotten skills.
I do find that writing on paper is important, and helpful to not lose certain tasks. It is also helpful when I'm learning, even if those notes never make it to more long term storage. I find comfort writing things down, especially TODOs, since they won't be forgotten. It also helped me when I was learning Go, or Kubernetes.
The other thing I've learned in my career is that everyone is different. I've stopped trying to convince anyone that 'my way' is better. It's only worked for me, that much is certain. Can I learn new tricks as an old dog? Sure, for example, I recently learned to use 'ripgrep' and it's my new go-to tool.
Be open to new things, but also try and optimize what is best for you. Peace and happy thanksgiving for those that celebrate!
