But they are closed, i.e. require you to be in the oxford network, though not necessarily with an Oxford login.

Idea: make all Sitare University materials open, and allow students to write the content
The courses are highly open, almost everything is given publicly except solutions, many of which are given to teachers only. Well done!

Free University Brighton has been working since 2012 to provide an alternative and for the last five years we’ve been running ‘freegrees’. These are University level courses, open to all regardless of qualification. Our courses range from 4 week long introductory courses aimed at First Years (people who have never been to University before) to 12-week long Humanities, Social Sciences and Philosophy courses that rival anything in a ‘traditional’ University. We do this all with no money exchanged anywhere - no fees, no debt.
Shut up and show us the courses.

Other mentions of "Denis Petrov":
In 2025, the FBI got interested in the creator of the website due to its news paywall circumvention usage, and the dude started going nuts, coming after anyone who had previously investigated him with OSINT, e.g. the author of gyrovague.com and Ciro Santilli:
Later on in 2026 Wikipedia banned archive.today links because it had DDoS'ed Wikipedia and tampered with snapshots: arstechnica.com/tech-policy/2026/02/wikipedia-bans-archive-today-after-site-executed-ddos-and-altered-web-captures/ The dude had gone completely unhinged, destroying everything he built.
Previously, updates were being done with more focus to sponsors in the format of the child sections to this section. That format is now retired in favor of the more direct Section "Updates" format.
This section contains the a list of cool things Ciro Santilli has been up to in chronological order, including small quick ones. Many/most of those are also posted on Ciro Santilli's accounts such as:
