Making machines do interesting things.

A fictional dog-card economy with committed drops, rarity, anonymous wallets, spot trading, synthetic liquidity, derivatives, and business decisions that flow into the books.

Server activity becomes privacy-safe double-entry bookkeeping: a German-style Bilanz and GuV, public journal, supplier debt, hourly settlements, realistic hosting costs, and fictional taxes in EUR.

Form one network, commission and discover its devices, bind clusters, then personally transmit every command, report, forwarding hop, and acknowledgement—with every PPDU octet explained.

A tiny Game Boy Color-style world for YIFF identities. Meet other creatures in Bramblewick, then fight Mirefang to make your character visibly stronger.

A browser chat speaking a binary protocol over WebTransport. Identity claims use four-character labels, and every message is separately encrypted with AES-256-GCM.

The implemented wire specification: exact frame layouts, bootstrap claims, HKDF key derivation, nonce ranges, replay handling, and worked byte-level examples.

Privacy-filtered Nginx and fallback request logs grouped into an inspectable dashboard. Sensitive fields are redacted, and client addresses are never published.

A shared household task board for recurring jobs, due dates, completion history, and lightweight Telegram planning.

A readable userspace Ethernet, IPv4, ICMP, and deliberately tiny TCP implementation. Follow real packet values through every parser, state transition, timer, and reply byte.

The assembly HTTP/1.1 edge that answers this host: every path a request can take, on one screen, anchored at the system calls each stage makes — accept, handshake, parse, route, proxy, gzip, log.
