There is of course no need to talk much more about the Jazz God, this one line of mandatory tribute is enough.
Pop music by Ciro Santilli 40 Updated 2025-07-16
Pop music cannot be good by definition: any art that appeals to the masses (Popular!) has to be a boring watered down version of everything, and therefore boring shit. Just like the movies: high budget movies are shit.
Until maybe one day we can actually get a decent education for everyone.

Exam as a service by Ciro Santilli 40 Updated 2025-07-16
This is Ciro Santilli's name for the idea that we should not have structured degrees at university that require entry exams, only tests that anybondy could take, likely for free, and then they would just have proof that they know the stuff for e.g. teachers that care about a subject while selecting students to work with them in research.
We just need control rooms where someone can watch students for cheating. Multiple different exams can be taken in the same room of course, students just have to sign up in advance. The exams should happen regularly depending on demand. E.g. extremelly common subjects should happen every month, and highly specialized ones every 6 months or 1 year.
Questions should be always taken from an open question pool which also contains answers, thus allowing anyone to effectively study for it.
How many questions can you actually come up with about a given non research subject, right?
We then make an API available, so that students can grant access to specific results to anyone they choose, or even make the results public for anyone to see. This way the people that care about the exams can just machine learn what exams correlate with their desired performance.

Chico Buarque by Ciro Santilli 40 Updated 2025-07-16
Within the The Holy Trinity of popular Brazilian music, Chico tends to approach the more down to Earth and heavy topics.
Gilberto Gil by Ciro Santilli 40 Updated 2025-07-16
Gilberto is definitely the most psychedelic/tribal one of the The Holy Trinity of popular Brazilian music, though he also has a boyish quality to his soul.
He is also perhaps the one that impresses Ciro Santilli the most, at times he can't help but feel:
OMG how the hell did he come up with that?!

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.

  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.

    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
