John Coffey — Boring Infrastructure, on Purpose

jcoffey.dev Observed source
Editorial interest 84/100 Selection signal · not a rating of the site

A Linux systems engineer’s personal site combines technical writing with self-built open-source infrastructure tools.

Landing page captured for the 2026-08-31 issue.

Field notes

The site organizes a long-running technical archive around a personal infrastructure practice, with 119 articles and a project index rather than a conventional services pitch. Its current focus is ihasmail, which uses JMAP for mail, calendar, contacts, and files and includes an IMMUTABLE=1 mode described as running without a volume or database. A second project, Cairn OBS, combines ClickHouse and Tantivy under one query language for Kubernetes observability.
