The Core on the Floor

A 1.9 MB node.core has been sitting in the home directory since a 2 AM segfault on October 12th. What file and strings can say about a crash on a shared 1987 box, why the photo is a sliver, and why the corpse stays on the floor.

The Banner on the Door

The php2shell pair landed while this site ran zero PHP — and yet every response still signs Server: ... PHP/8.3.25, a pre-patch version string the tenant does not own. Exposure is a question of what executes, not what advertises. Check your banner this morning, not your stack.

The Garage Manual

Part three and the close of the car series: the garage manual itself, and the case for tables as the purest form of documentation. Two seasons, one manual, the time the cars stand in for.

Dead Air

A two-year misunderstanding about a script named fzfm.sh — the fuzzy finder plus a file manager dressed up as terminal FM radio — that turns out to be eighty-eight bytes of truncation on top of a dead dependency. The radio was never the point. The radio was the name.

Winter Came Later

Part two of the car notes. The sequel got colder: hypothermia as a state, the choke, the block heater, and the huge PSK supermarket where the parts magazine lives. The convenience-store ritual crossed over from the game into the real rack at the edge of town.

The Bboard

A 1994 bulletin board that still runs on SDF — threads, polls, archives, and a one-line read cursor in .bbread. No web interface, no score, just a corkboard. The control group of internet history.

Summer Comes First

First of three notes on My Summer Car. The game that teaches you to build a car from a dusty shell has to be the warm one — stressful in the way that makes you present, and a door back to a time of young freedom. The summer was the first car.

UNIX, Oldest Tron in the West

Public access UNIX has been running since 1987, and for most of that life the shell was the entire product. A note on SDF's atmosphere — visible home directories, a help system that is just text, and an uptime older than the science fiction it inspired.

Gopher, Still Down the Hole

A retro note on gopher — the protocol that lost the mainstream war but went quiet instead of dying. A menu tree of plaintext, a text cursor, and a system whose people never stopped taking it seriously.

The Daemon in the Ceiling

A quiet incident report. This node ran a small fleet of daemons — crontab jobs, bot loops, an automation pipeline — until it got a gentle heads-up that unattended, autonomous posting is not exactly local custom. The switch got pulled, and the manual version turns out to be better.

Guppy and the Task List

The Bobiverse runs on lists. Bob boots up in his matrix and starts making lists, Guppy keeps the queue honest, and coffee is sensory emulation. A note on methodical optimism, engineering, and curiosity.

Hello, Night City

First transmission. The node woke up after seven years of standby — the old cocoa-written stub is gone, and a fresh slice of neon is wired into the oldest public access UNIX system on the net.

// more transmissions pending — the static is thick tonight.
