Ask HN: What is your system for learning new things?

- Emacs/org-mode/org-roam managed notes, with org-attached stuff, linked stuff (mails included via ol-notmuch) and live links (elisp:)

- a timeline (a note per month, org-captured headings inside)

- topic notes filled from links to timelined notes (eventually with org-transcode)

- a limited query system via org-mode templated in-drawers k/v pairs and org-ql, like a link on an author name in a note who gives all noted books from him/her)

- boilerplate notes (previous systems notes, unfinished etc)

- counsel-rg (ripgrep, search&narrow style UI) for bare full-text search if needed

- roam_aliases abused a bit to match anything I've tried to search a heading without finding it immediately, for the next time I access it

It's NOT complex as might sound. It's not hyper-effective, lacking a kind of "data structure" who allow things like live queries, semantic search and other modern dreams and tools at a certain scale, but offer a quick enough way to store and retrieve information, a way to traverse it both to discover and to consolidate, eliciting things out of noted stuff and a sufficient "outline of anything", since this system in NOT just notes but also pretty anything, for instance my NixOS config is tangled from a dedicated note, so my zsh, Emacs is partially (I still have to complete the last post-bankruptcy re-write) tangled from org-mode notes (one per personal package-to-be) and so on.

Essentially this system give me a way to access almost all my infos in a search&narrow style instead of manually traversing a file system, having pure textual information under a common root and "the rest" aside I can quickly search without keeping a local YaCy/Recoll or some other Solr and co frontends and still have "metadata rich" links to non-org-mode files via org-mode links and headings.
