Image and asset credits

This page lists where everything visual on this site comes from. The short version: the cover graphics are generated by our own build process, and the only third-party assets are two typefaces served by Google Fonts.

Article cover graphics

Every article carries a schematic cover. These are not photographs and they are not stock illustrations. They are SVG documents produced at build time by a generator in ssg/covers.py, seeded from a hash of the article slug so that a given article always produces the same graphic and no two articles share one.

Author

WPSifero, produced by the site build process.

Licence

All rights reserved, as part of this site's content. You may reuse a cover alongside a link to the article it belongs to; stand-alone reuse needs permission.

Motifs

Waveform, bit-matrix, schematic, barcode field and contour. Five motifs distributed across the archive so that the index grid does not become uniform.

Photography

There is no stock photography in the article archive. Technical writing about database indexes and session cookies does not improve with a photograph of a laptop on a desk, and the alternative, licensing images per article, adds a maintenance burden that produces no reader value.

No third-party photography is used on this site. Article covers and diagrams are generated in-house; see above.

Typography

Two typefaces are used, both served via Google Fonts.
