Comprehensive Guide to 32-Bit RISC-V Assembly Programming (RV32I)

Comprehensive Guide to 32-Bit RISC-V Assembly Programming (RV32I)

This guide provides a thorough introduction to programming in 32-bit RISC-V assembly language, focusing on the RV32I base integer instruction set. It starts with content from this cheat sheet and expands it into a complete, structured reference. The guide is organized for easy navigation, with clear sections, tables for listings, explanations, examples, and notes. It draws from official specifications and tutorials to ensure accuracy and completeness. Beginners can follow sequentially, while experienced users can reference specific sections.

Key assumptions:

  • We use the GNU Assembler (GAS) syntax, common for RISC-V tools.
  • Examples assume a bare-metal or simple simulator environment (e.g., RARS, Spike, or QEMU).
  • RV32I is the base; extensions like M (multiply/divide) are noted but not required unless specified.
  • Code snippets are testable in simulators; error handling and overflows are ign

Stop using JWTs

Stop using JWTs!

TLDR: JWTs should not be used for keeping your user logged in. They are not designed for this purpose, they are not secure, and there is a much better tool which is designed for it: regular cookie sessions.

If you've got a bit of time to watch a presentation on it, I highly recommend this talk: https://www.youtube.com/watch?v=pYeekwv3vC4 (Note that other topics are largely skimmed over, such as CSRF protection. You should learn about other topics from other sources. Also note that "valid" usecases for JWTs at the end of the video can also be easily handled by other, better, and more secure tools. Specifically, PASETO.)

A related topic: Don't use localStorage (or sessionStorage) for authentication credentials, including JWT tokens: https://www.rdegges.com/2018/please-stop-using-local-storage/

The reason to avoid JWTs comes down to a couple different points:

  • The JWT specification is specifically designed only for very short-live tokens (~5 minute or less). Sessions

LLM Wiki

A pattern for building personal knowledge bases using LLMs.

This is an idea file, it is designed to be copy pasted to your own LLM Agent (e.g. OpenAI Codex, Claude Code, OpenCode / Pi, or etc.). Its goal is to communicate the high level idea, but your agent will build out the specifics in collaboration with you.

The core idea

Most people's experience with LLMs and documents looks like RAG: you upload a collection of files, the LLM retrieves relevant chunks at query time, and generates an answer. This works, but the LLM is rediscovering knowledge from scratch on every question. There's no accumulation. Ask a subtle question that requires synthesizing five documents, and the LLM has to find and piece together the relevant fragments every time. Nothing is built up. NotebookLM, ChatGPT file uploads, and most RAG systems work this way.
