The continental United States at night: a glowing blue highway runs coast to coast through seven bright stops, the brightest in amber on the Great Plains.

The Cheapest Way Across America

New York to Los Angeles: why the classic greedy for the gas station problem breaks on real roads, the dynamic program over fuel levels that replaces it, and how to place 6,600 truck stops that have no coordinates.

A laptop on a dark desk shows a terminal with five glowing tabs; thin blue and violet threads run from each tab to a matching card on a phone beside it, one pair highlighted in violet.

The Phone Is Just Another Tab

Every interactive Claude Code session on my Mac now starts on Remote Control, carries its iTerm2 tab's name to my phone, and is archived there when it ends on the Mac. What stock Claude Code already does, the three gaps I closed, and how I verified it.

A glass hourglass shatters into glowing shards while a blue line of light runs on past it through seven glass panels, from moonlit night to sunrise, above a city.

The Five-Hour Wall Comes Down, One Account at a Time

Anthropic renamed Max 20x to Ultra and is lifting its five-hour limit account by account, after an automatic check. What changed, how to check your account, why the five-hour bar may still be there, what a week-only budget means for agents, and the one rule my status line now follows.

A path of glowing blue lanterns, the nearest one lit amber, curves past a vast field of unlit lanterns under a violet orb that sends threads of light down to the path.

The Next 900

This publication passed 100 members. Most of October's 78 new members likely came through a channel that analytics barely sees. What brought them, what Ghost's growth guide gets right and misses, a checklist any Ghost publisher can run this week, and a measured plan for the next 900.

A dark law library: an open book on a stone table unfolds into floating glass legal tools, a tracker, a timeline, a document comparison, a radar, a checklist, with copies sent to every seat.

Claude Wants to Be Legal's Front Door

Claude for Legal now offers ready-made tools, not just a blank chat box: review tables, cite checks, matter boards and intake desks, with Harvey, Goodwin, Foley & Lardner and PwC building inside it. What shipped, what the docs add, and who should worry.

A rain-soaked hall: a black slab with one glowing cursor sends blue threads to tiers of glass modules, ringed by gauges and sliders, as light flows from an amber cell to a blue one.

My Self-Tuning AI Harness

Claude Code, extended instead of wrapped in an app: one command for every project and account, work that moves to another account at a limit, subagents on a benchmarked model table that can retune itself, and a harness that reads its tools' news and repairs itself.

A lone caped robot under a spotlight in a rainy arena, beside a melting server-snail with a cracked hourglass, a burst coin vacuum and a smashed black robot.

Only Claude Survived

The local agent passed a controlled test and failed real work: tasks Opus 5.5 finishes in 10 to 30 minutes took it hours. It's gone, along with every agent that isn't Claude and about 452 GiB of disk.

Satirical cartoon: a haloed Sam Altman caricature holds a $1,000 SORRY! cheque while a CODEX vacuum sucks coins from a sleeping developer's laptop; robots stare at a locked door.

Fuck You OpenAI

And Fuck Sam Altman Too

A large analog gauge in a dark server hall, its needle swept past the blue arc into a glowing amber outer arc, with streams of light running to rows of server racks.

Overtime: When the Plan Runs Out, Credits Take Over

My harness stopped Claude Code and Codex at 95% of their plan windows, even when usage credits could have paid for more. Now it checks for usable credits first, keeps working until they run low, and says so in the status bar.

A steel rotary selector set into a concrete plinth, its pointer lit amber, beside a tower of stacked concrete slabs edged in blue light in a dark brutalist hall.

The Thinking Dial

What reasoning effort really changes in Claude Code, Codex and local models: thinking tokens, tool calls, cost, wait and usage limits. The evidence, the defaults that move under you, my own harness settings, and how to choose a level.

Two men talk on a sofa in a night-lit apartment; beside one man's gesturing hands a glowing node bursts into light paths, and light trails fan out from one point over the skyline.

The Switchboard: OpenRouter, Explained

One API key, about 350 models, dozens of hosts behind the popular ones. A complete guide to OpenRouter: how its routing, prices and privacy really work, how coding agents plug in, and where it would fit a three-agent harness.

A glowing violet cube rises from a processor at the center of a circuit-board city at night, while two cloud cities above it send thin beams of light down to the chip.

The Third Mind: Local AI for When the Cloud Runs Out

OpenCode on open-weight models, running on a MacBook Pro beside Claude Code and Codex: the agent that works when both are out of quota. Memory, prompt caching, uncensored models, self-updating lineups and a coding duel with Claude.
