What Hacker News says

Based on discussion on HN several days ago, I have started using Hashcards (markdown-based flash cards with FSRS; run from command line, but view cards in the browser). Once set up, it's pretty simple (e.g., no fiddly settings) which helps a lot. Getting new cards added is easy — especially with a Keyboard Maestro macro that I made (global keyboard shortcut pops up a window to enter Q/A and select a deck, i.e. md file, to append to; entering text only on the Q line creates a cloze-deletion card instead). Recommended. My use case is drilling English --> target-language sentences, as well as law-related knowledge, miscellaneous facts, etc. Still mulling over what to do about other skills-based practices, à la Andy Matuschak's concept of "spaced everything". - Hashcards: https://github.com/eudoxia0/hashcards - HN discussion about Hashcards:

Thank you, finally a SRS implementation I can use for my plain text files. Very nice! I had Gemini make a deck from https://github.com/eudoxia0/hashcards , hashcard_tutorial.md and after correcting my deck to account for escaping the < and > with \< and \>; on the second run ($ hashcards drill --card-limit=10 ./)dealt me all the correct cards, like a self QA I really like the keyboard shortcut of space and 1,2,3,4 for making deck reviewing quick work.
