These are research institutes usually funded by rich tech bros, sometimes cryptocurrency magnates, but not necessarily.

kenorb by Ciro Santilli 37 Created 2024-11-04 Updated 2025-07-16
Ciro Santilli feels that this user has a surprisingly similar contribution pattern (one of the top necromancers) and subjects (Python, Bash) to Ciro Santilli.
Ciro tried to contact him to say hi, but it was hard to find a contact. kenorb, feel free to send Ciro a hi one of those days. Ciro knows kenorb knows Ciro exists because kenorb has in the past starred some of Ciro's stuff, e.g. github.com/cirosantilli/bitcoin-inscription-indexer from Cool data embedded in the Bitcoin blockchain.
His GitHub github.com/kenorb gives name Rafal W. and links to some trading stuff: github.com/EA31337, especially compatible with his stated location of London.
Rafal is Rafael in Polish: en.wikipedia.org/wiki/Rafał It would normally have the l with a stroke, but ASCII.
His LinkedIn sys the R3 company he works at is actually a blockchain company: en.wikipedia.org/wiki/R3_(R3CEV), FOREX appears to be his on-the-side.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

    . View it live at: ourbigbook.com/go/topic/derivative
  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
    Figure 5. . You can also edit articles on the Web editor without installing anything locally.
