View:
Deployment Prep and Backend Growth
Kubernetes/K3s deployment configs, CI/CD scaffolding, schema-driven API generation, and the Star Trek BASIC backend.
Three Languages, One Weekend (Sort Of)
Building BASIC, Forth, and Scheme interpreters in Rust, running them in browser workers, and what that architecture taught me about language shape.
The Big web/ Move and Parser Migrations
Moving the web app to a proper structure, migrating parsers to Pest/Pratt, and building the Z-Machine opcode engine.
Deep Dive: CTS Flow Control in the Serial/Modem System
Why you can't just shovel bytes through a virtual modem—RTS/CTS backpressure, buffer gates, and the timing budget that makes dial-up feel real.
Deep Dive: The Z-Machine Interpreter
Building a Z-Machine transpiler in Rust—opcode decoding, Z-strings, branch offsets, and the constraints that make Infocom's bytecode tick.
Z-Machine Foundations and Storage Sync
Pushing the Z-Machine interpreter forward with decoder work, text handling, and SAVE/RESTORE—plus content-addressable storage with S3 sync.
The Dungeon Gets Real
Transforming a dungeon crawler demo into a persistent roguelike with progression, daily challenges, and meta-unlocks—all in one session.
Emulation Milestones and TypeScript Migration
Intel 8088 demos, Zig-based 6502 experiments, and migrating the frontend to TypeScript for better type safety.
Deep Dive: PETSCII and the VIC-II Text Adapter
Translating PETSCII screen memory into ANSI terminal output—character maps, colour translation, and the minimal contract a terminal-based VIC‑II can keep.
Big Repo Restructure and Backend Migration
Splitting the repository into clear domains—cores, languages, assemblers, BIOS—and making future work less of a guessing game.
Build System Groundwork and Modem Plumbing
Tightening the build pipeline for modem-core WASM, dynamic backend loading, and making the modem behave like a real modem.
Deep Dive: Bell 212A and V.32bis Handshakes
When 300 baud isn't enough—simulating faster modem handshakes with phase modulation, training sweeps, and the controlled chaos of negotiation audio.
Deep Dive: Bell 103 Audio Modem and FSK Implementation
Implementing the 1962 modem standard that made 300 baud dialup possible—FSK modulation, Goertzel demodulation, and the two-band trick that keeps full‑duplex honest.
A Small Day That Mattered
Fixing CRT modem and BBS bugs—the quiet foundation work that keeps a larger project from getting weird later.
Raspberry Pis and APRS
The first implementation of an APRS-IS Tier2 server and iGate using Raspberry Pis.
Tuning the Butternut HF9V
The second round of tuning the Butternut HF9V took place a few days after the storm on installation day.
Butternut HF9V Installation
Assembly and initial installation of the Butternut HF9V multi-band ham radio antenna.
