QEMU Emulator Tour -- How I Emulated x86 in C
One session. The dynamic translator, the TCG, the device model, the memory map. After this you will know how VMs actually work, not just how to run one.
TinyCC Source Bundle -- a 300KB C compiler
The TinyCC source bundled with my notes on why each module is structured the way it is. Free. Read it. Learn. Compile it. Fork it. Do not thank me.
Redis Internals Bootcamp -- 4 sessions
Four 90-minute sessions. We read Redis source together -- event loop, key expiration, the AOF. You walk away able to find a memory leak in anybody's C code. Bring a laptop and a kitchen light.
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.
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.
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.
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.

Women's Self-Defense Course -- 4 weeks, Enna
Four 90-minute sessions designed for women, by a boxer who has spent 12 years learning what strikes land and what does not. Practical, repeatable moves you can use in the street, in the carpark, in the elevator. No ego, no tough-guy nonsense. Small group (max 8). You will leave able to defend yourself from the most common grabs and attacks -- and knowing when to run, when to shout, and when to fight.
Raffle: 1 Private Coaching Session
One hour private coaching. EUR 1 ticket, 10 tickets total, draw in 2 weeks. Proceeds go back into gear for the community youth program.
Original ice axe -- my 1978 K2 climb
Not for sale. On loan for museum display, school talks, or serious climbers who want to hold the piece. Free. Treat it like your first child.
Free "Is this for you?" session + gum shield -- first 20 kids
