This site
a Pointer to J is a wiki that grows: one page per topic, and new problems, fixes and notes go into the page they belong to. It started in November 2017 and has since changed hosts eight times and domains six times (the Changelog keeps them all). Today I write in my own desk app and publish plain static files, served by a tiny read-only program with no database behind it.

No trackers, no cookies, no analytics, no fonts or scripts from anywhere else. Your browser keeps two things for you, and only for you: when you last read each page (for “since your last visit”) and your theme choice. Nothing is sent back. Like any web host, Cloudflare, which serves these files, sees each request’s address to deliver it. Questions or corrections: jeon@ptrtoj.com.
