1 pages

GIS

Geographic information systems: data tied to places, stored, analysed and drawn as maps.

5 pages

Internationalisation

Designing software so every text can be translated; this site exists in English and Czech, and a gate fails on any untranslated text.

1 pages

JSON-LD

Linked data in JSON embedded in a page, telling search engines and machines what the page is about (schema.org).

3 pages

Repository

A project's folder under version control: its files and their whole history of commits.

58 pages

Static site generator

A program that turns content and templates into plain files before anyone visits, so the site needs no server code.

WCAG

The Web Content Accessibility Guidelines; every page here is checked against WCAG 2.2 level AA before it ships.

Article

Glossary

The glossary is the shared language of the whole site. Every page names the terms it builds on in its front matter and ends by explaining them; a term’s page in turn shows every page that uses it and the terms that appear alongside. These links are derived, never typed by hand.

Each definition is short, in plain words, and points to a source to read further: documentation, a specification or an encyclopedia. Terms come in three kinds: programming languages, technologies and concepts.

The map at the top draws the same links as a network: every term is a star, larger by the pages that name it, and threads lead to the terms that appear on the same pages. Such a map is called a co-occurrence graph; the terms at its centre are the ones that hold the site together.
