SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It helps you create a reliable spaced repetition flashcard system so you can study and memorize information with long-term retention instead of relying on ad-hoc review.

Core Features & Use Cases

  • Browser-accessible spaced repetition app: Runs a hashcards instance you can use from a web browser at a stable Zo Computer URL.
  • Atomic card format with cloze support: Stores cards as plain text files and supports Q&A cards plus cloze deletions for targeted recall practice.
  • FSRS-driven scheduling with rich formatting: Uses the FSRS algorithm to optimize review intervals and supports Markdown and LaTeX (KaTeX) in your cards.
  • Persistent auto-restarting service: Registers the server as a persistent user service so it survives reboots and restarts on crashes.

Quick Start

Use the skill hashcards-setup to set up a running hashcards spaced repetition instance at https://srs-<your-username>.zocomputer.io and store your cards in /home/workspace/flashcards/.

Frequently Asked Questions about hashcards-setup

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I set up a spaced repetition flashcard system in my browser?▼

This setup uses the FSRS algorithm for spaced repetition scheduling, optimizing your review intervals for long-term retention. It supports creating Q&A cards and cloze deletions stored as plain text files for targeted recall practice.

Do I need Rust and Cargo to compile the hashcards flashcard server?▼

Yes, you need Rust and Cargo installed to compile the hashcards binary, along with SQLite dev libraries. Git is also required to fetch the source code before you can build and register the persistent web service.

Can I use Markdown and LaTeX formatting in my flashcards?▼

Yes, the flashcard system supports Markdown and LaTeX rendering via KaTeX. You can format your Q&A and cloze deletion cards with rich text and mathematical equations directly within the web interface.

How do I keep my spaced repetition web service running after a system reboot?▼

You register the flashcards server as a persistent user service with the correct entrypoint and PATH. This auto-restarting configuration ensures the HTTP service survives reboots and restarts automatically if it crashes.

What are the limitations of running a self-hosted flashcards web service?▼

Running this spaced repetition web service requires compiling a Rust binary with specific SQLite dependencies and manually registering a persistent HTTP service on port 8000. You must also validate the public HTTPS endpoint responds successfully to ensure access.
