Automation & AI
I like making repetitive work disappear.
Scripts, integrations and AI-directed builds; 7 machines at home run from one repository. I run AI agents and harnesses daily and use generative AI for anything I can.
What I handle
- Declarative infrastructure, one repository describing every host
- Shell scripting and scheduled jobs
- Monitoring and alerting kept short enough that people read it
- Wiring systems together where no supported integration exists
- Reading and writing structured data: logs, exports, reports, registers
- Linux hosts, services and the small jobs that keep them predictable
- Directing AI tooling: writing the brief, checking the output, deciding what not to hand over
- AI agents and harnesses: opencode, Claude Code, Codex, Gemini CLI — used daily, disclosed on every build
- Generative AI for research, writing, code and data tasks wherever it helps

Case studies
From a 1998 source dump to a clean-room Rust IRIX
The 6.5.7m kernel rebuilt from its source dump, the binary-only drivers relinked, and a Ghidra fork taught to read MIPSpro binaries.
jupiterOS
One declarative computer for a seven-machine home fleet.
The household automation estate
Eleven n8n workflows that run my life admin.
Fourteen hours on one build
A microarchitecture mismatch and an NFS fix.
LG webOS TVs inside Home Assistant
model-router
One OpenAI-compatible endpoint pooling LLM upstreams, tested with five chaos drills.
ha-linux-agent
A Rust daemon with ten backends that puts Linux hosts inside Home Assistant.
Lab notes
Fourteen hours on one NixOS build: a microarchitecture mismatch, eleven failed closures and an NFS attribute-cache fix, documented in a 505-line handoff.

The desk blanks itself after a quiet spell, then runs one of thirteen effects named after the IRIX screen savers. Move the pointer or press a key to wake it; lock it and only Unlock brings it back.
Settings load with the desktop.
The environment
About this desktop
jupiter.au is set up as a working desktop: the Toolchest, the objects, the status strip and the windows stay with you on every page. Drag a title bar to move a window, pull any edge or corner to resize it, drag it to the side of the desk to snap it into place, and right-click a title bar for that window's menu. Right-click the desk itself for the root menu.
Toolchest
The panel in the corner carries the classic seven menus — Desktop, Find, People, Applications, Shared Resources, System and Help — above the command field. Collapse it to the chip with the arrow in its title strip, or press Ctrl+K to bring it back.
Desks
Four desks, as 4Dwm kept them. Each surface belongs to the desk it was opened on — switch with the status strip, the Toolchest, or Ctrl+Alt+1…4. The Desks Overview window maps all four at once.
The catalogue
The Icon Catalogue lists every application the desk knows — click to select, double-click to open, right-click for the icon's own menu. The objects on the right edge can be dragged into a new order, and the one that will take the drop turns royal blue.
Customise
Desktop → Customise… holds the background (signal wash, flat or dim), the bevels (flat 2026 or the classic two-line), and the way to the Screen Saver. Choices stick to this machine.
Screen saver
Thirteen effects named after the IRIX screen savers, with a timeout, a Random mode and an optional lock. Open the Screen Saver window to change them.
