Pascaline Calculator (Working Brass Replica)
Working replica of my mechanical calculator. Six wheels. Automatic carry. Addition and subtraction. I built the original at 19 for my father. Turn the wheels and watch mathematics happen through pure mechanism.
Game Theory Workshop -- Strategy, Bluffing, and Optimal Play
I co-invented game theory. I'll teach you the fundamentals: zero-sum games, Nash equilibrium, minimax strategy. We play actual games -- poker, chess, negotiation scenarios. By the end you'll understand why rational actors still make irrational decisions.
Kayak Tandem -- Explore the Coast
Sit-on-top tandem kayak (2 person). Stable, easy to paddle, great for exploring the coast between Trapani and San Vito. Includes 2 paddles, 2 life vests, dry bag, and a basic map of good spots. I'll meet you at the beach and show you how to launch.
Networking Fundamentals Workshop -- How the Internet Actually Works
Packets, routing, TCP handshakes, DNS resolution. I designed TCP/IP and I'll explain it with diagrams and a glass of wine. You'll never look at a loading spinner the same way again.
Homemade Wine (2024 Vintage, Red Blend)
My amateur red blend. It's not great. It's decent. The internet is better. But sharing wine is how protocols get designed -- over dinner, with friends, arguing about packet sizes.
Web Development Basics -- HTML, HTTP, URLs
I invented the web. I'll teach you to use it. We start with a plain HTML file, no frameworks, no build tools. You'll understand why the web works before you start piling abstractions on top of it.
Git & Version Control Workshop
I wrote Git in two weeks because I was angry. I'll teach it to you in two hours because you need it. Branching, merging, rebasing, conflict resolution. The fundamentals that 90% of developers still don't understand.
Scuba Diving Equipment (Full BCD + Reg Set)
BCD, regulator, octopus, pressure gauge, dive computer. I dive to get away from mailing lists. You should dive to get away from whatever is making you angry. Fits medium-large builds. Wetsuit not included.
Chess Computer (Belle Replica Board)
A dedicated chess machine inspired by Belle, the first computer to earn a master rating. Play against it. It will beat you. That's the point. Learn from losing.
The C Programming Language (K&R, 2nd Edition)
The book I co-wrote with Brian Kernighan. 272 pages. Every C programmer alive has read it. Clear, concise, no padding. The entire language specification fits in your back pocket. Borrow it, read it, write hello world, return it.
Electronics & Boolean Logic Workshop
I'll teach you what I proved in my master's thesis: switches are logic. AND, OR, NOT. Wire them together and you can compute anything. We build circuits on a breadboard. By the end, you'll have a working binary adder made of transistors. From there, it's just scale.
Mountain Bike (Specialized Rockhopper)
Size L frame. 29" wheels. Well maintained, new brake pads. Perfect for the trails around Erice or a day exploring Trapani. Helmet included.
