This is an official ODERSA website. Here’s how you know

The official domain

The address of this site ends in odersa.org. Every service the association runs sits on a subdomain of odersa.org and nowhere else. If the address in your browser’s address bar does not end in odersa.org, this site is not ours.

Free, and no account

Everything is open straight away. No sign-up, no account, no password, no subscription, no advertising. Nothing is held back for those who pay, because there is nothing to pay for.

No data collected

This site does not follow you: no tracker, no tracking cookie, no measurement tool built into these pages, and nothing measured on your device. Our host counts requests in aggregate, as any server that answers does: a total, never a profile. You do not have to take our word for it: open your browser’s developer tools, go to the Network tab, and reload the page. You will see the full list of what the site asks for. Everything comes from odersa.org, nothing goes anywhere else.

Free to reuse

The content is published under the CC BY 4.0 licence. You may copy it, translate it, print it and pass it on, for your classes as much as for the people around you, on one condition only: credit ODERSA.

Choosing your path

Three paths lead to the same course, chosen to fit the situation rather than ranked by importance. This page says in one sentence what each one brings, so you can decide without opening them.

The three paths below go through the same course: only the order of the chapters and the examples change, never the content. Coming in through the wrong door makes you miss no chapter, since each path leads to the same place by a different route.

The three paths

For teenagers

Reading on your own, with no class and no marking: the path starts with the mechanism and ends with the habits that matter when facing a homework assignment, an image going round or a call that imitates a familiar voice.

For work

Professional use of artificial intelligence: the path starts with what you hand to a tool and the line to draw, before the mechanism itself.

For teaching

A course to prepare without official material: the path groups the nine chapters into sessions, with one session ready to use as it stands and the traps to avoid.

None of the three fits

The course also reads from end to end, without going through a path: its full contents are on the understand page, and its demonstrations can be used on their own. Every page on the site, grouped by theme, is gathered on the site map.
