Why “post no bills”?

Post no bills” is the warning stenciled on construction fences and scaffolding around New York. A bill, in this usage, is an advertisement. The instruction is simple: don’t paste one here.

White plate sign on a light-green wall, straightened but marked with a small sticker. Crisp white stencil on smooth dark-green masonry, with the N set at an angle. Weathered white stencil on dark-green plywood with brush marks. Soft-edged white stencil sprayed on teal-painted plywood. Faded white stencil seen through black construction mesh. Weathered bilingual white plate sign mounted on a teal-painted door.
Six variations around New York.

That’s where the name comes from. This is my personal site: essays and links, mostly about AI agents, engineering, and New York. There are no advertisements here, including advertisements for the site itself.

The name is context, not a theme. The site isn’t going to imitate plywood, paper, scaffolding, graffiti, or a stencil. The photographs can show where the name came from; the rest should read like a publication. The writing is the product.
