Kernel Patch Review -- free, and I promise to be kind

Email me your kernel patch. I will review it. I owe the community this one. You get honest feedback. Free. You do not even have to say thank you. But it will be kind -- that is the deal I made in 2018 and I am keeping it.

Git From First Principles -- it is just a content-addressable filesystem

My retired 2017 XPS 13. Arch, kernel 6.8 with my own patch set, suspend works, webcam works, trackpad is set up the way I like it. Boots in 3 seconds. If you want to see how I use a computer, borrow this for a weekend.

Rework -- signed, scribbled in

My own working copy of Rework (2010). I wrote it with Jason. The margin notes are my regrets and upgrades -- things we'd change ten years on. Read them before you argue with the book.

Training
€25 per session

Framework Extraction Workshop -- pull a library out of your real app

Three sessions. Bring a real codebase. We find the patterns worth extracting, pull them into a gem, and ship both the product AND the library. The Basecamp-to-Rails move, but on your code.

Service
€30 per session

Rails Code Review -- I will tell you the truth

One hour. Push a branch, walk through it with me. I will be honest. Some people cry. Some people ship better code the next day. Most do both.

FFmpeg From Scratch -- 2 hours, from fopen to H.264

We read the original FFmpeg source. I walk you through the demuxer, the codec, the filter graph, and the mux. By the end you will understand why every video on the internet passes through this code.

Hacker's Delight (annotated -- my margin notes)

My personal copy of Hacker's Delight by Henry S. Warren Jr. Every bit-twiddling trick I ever used came from here. My margins are covered in Italian swear words where a theorem surprised me. Handle carefully.

Service
€15 per session

Solo-Hacker Setup Tour -- Vim + tmux + why I never used an IDE

One hour. I show you my 2009 editor config. We argue about keybindings. You leave with a setup that lets you ship features without your hands ever leaving the home row.

Inner-Loop Consult -- I make your hot path fast
Service
€50 per session

Inner-Loop Consult -- I make your hot path fast

One hour on a video call. You show me your profiler output. I tell you what 30 lines to rewrite. Works for graphics, numerics, sim, game loops. Does NOT work for web backends -- that is a different sport.

Quake Engine Source Tour -- 2 hours, commented
Service
€40 per session

Quake Engine Source Tour -- 2 hours, commented

We walk through the Quake engine line by line. BSP trees, visibility, collision, the network code. You will see why the game shipped on a Pentium 75 and still looked like magic.
