Through Time

Through Time is a set of open courses for an age when a machine can do your thinking for you: how it works, how to work with it, and how to keep thinking for yourself. Free, in English and Russian, with no sign-up and nothing tracked. Your progress stays in your browser, and you can export it as a file.

The catalog has 22 courses in four strands: understanding the machine, developing your own mind, checking what you are told, and keeping what is yours. One course is written.

That course is The Web, End to End: 154 lessons in 17 parts, from the first web page of 1991 to the agentic web, for people who have never built a site. You describe a site of your own at the start and rebuild it in each era. Your 1996 page becomes a semantic page, then a responsive one, then a design system, and finally a site an AI builds from your brief, which you review with what you have learned. Each lesson has plain theory, diagrams, sources you can check, a quiz and a sandbox that checks the page you build. Every lesson can be heard: synthesized narration, about 22 hours in Russian and 25 in English, rendered on our own machine. Spaced repetition keeps what you learned.

The two editions are not literal translations. The English one puts GDPR and WCAG where the Russian one has Russian law.

A guide called Echo is on every page. It works with no key and no network. Bring your own model key and you can ask it questions; the key stays in your browser too.

Code is under Apache-2.0, lessons under CC BY-SA 4.0, and the source is public.

The other 21 courses are tables of contents and no lessons. The course on AI comes next, one lesson at a time. We promise no dates; a feed says when one appears. A course on law went up and came down the same day: law changes too fast for us, and stale law is worse than none.
