Compilers for Machine Learning

A hands-on one semester course where students build their own compiler from scratch, starting from elementwise programs and ending with training SOTA LLMs on GPUs. This course aggressively builds on the previous week, and is an exercise in slop management. If you let any slop in early, it will compound and you will not finish the class.

This syllabus will outline the spec, but not the implementation. The implementation and choice of programming language is up to the student. There is no starter code. We will establish a universal, simple, interchange format for UOps.

%1 = buffer : dtype=f32 slot=1 size=65536

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.

Beads Uninstall Script

A comprehensive uninstall/cleanup script for Beads (bd) that removes all traces of the tool from a system.

Usage

./scripts/uninstall.sh            # dry-run (scan $HOME)
./scripts/uninstall.sh --apply    # perform cleanup
./scripts/uninstall.sh --root DIR --apply

GitHub Pages File-Sharing

If you sometimes find yourself needing to share a file over HTTP, there are not many file-sharing solutions you can use.

This action works by publishing files via GitHub Pages behind an obscure prefix path. It updates the repository README with the URLs, so that you have links to the published files.

You can keep the repository secret, and the files are public but semi-secret, so you can share them without concern that other files will be discovered.

UNRAID NFS Configuration Guide - Complete Issue Resolution

Executive Summary

This document details the investigation, root cause analysis, and resolution of recurring NFS stale file handle issues in a home lab environment with UNRAID NAS and multiple Linux clients. The solution involved migrating from static NFS mounts to systemd automount configuration, eliminating stale handle problems while maintaining full container compatibility.

Environment Overview

Infrastructure

UNRAID Server: unraid-server (192.168.1.100) - Primary NAS with NFS exports
