Quick facts:
- Nationalities: Italian and Brazilian
- Grew up in: Brazil
- Relationship status 2017-: married
- Given name pronunciation: take your pick from Ciro Santilli's given name
- Chinese name: 三西猴, means "three western monkeys". Phonetic approximation to SANtilli CIRO. More info at: Ciro Santilli's Chinese name. Semi-unintentionally reminds Chinese people of Sun Wukong (孙悟空). This association is further slightly strengthened by the phonetic choice of 三 San, which Ciro later noticed matches the middle character of Tang Sanzang (唐三藏), the monk in Journey to the West. The given name 西猴 was given by Ciro Santilli's wife, then recent girlfriend, as a semi-joke, and he took it up because the best way to take a joke is to play along with the joker. 三 was chosen by Ciro himself.

- tabs or spaces: spaces
- Mailing list or Git(Hub|Lab): Git(Hub|Lab), with passion, see Section "Mailing list"
- system or unit tests: system
- programming languages: Python and C++. He'll learn Rust and Haskell once he's rich. As of the 2020s, Rust was picking up some serious steam, so Ciro might end up eating his own words there.
- musical instruments to listen: Chinese Guqin and electric Jazz-fusion guitar
- metric or imperial: metric, for The Love. Science? Standardization? 21st century anyone?

19th century illustration of the Journey to the West protagonist Sun Wukong
. Source. Sun Wukong (孙悟空) is a playful and obscenely powerful monkey Journey to the West. He protects Buddhist monk Tang Sanzang, and likes eating fruit, just like Ciro. Oh, and Goku from Dragon Ball is based on him. His japanese name is "Sun Wukong" (same Chinese characters with different Japanese pronunciation) for the love. His given name "Wukong" means literally "the one who mastered the void", which is clearly a Dharma name and fucking awesome in multiple ways. This is another sad instance of a Chinese thing better known in the West as Japanese.
It is worth noting however that although Wukong is extremely charming, Ciro's favorite novel of the Four Great Classic Novels is Water Margin. Journey to the West is just a monster of the week for kids, but Water Margin is a fight for justice saga. Sorry Wukong!
The photo was taken in an open event organized by the awesome Cambridge Synthetic Biology outreach group, more or less the same people who organize: www.meetup.com/Cambridge-Synthetic-Biology-Meetup/ and who helped organize Section "How to use an Oxford Nanopore MinION to extract DNA from river water and determine which bacteria live in it".
Taking part in such activities is what Ciro tries to do to overcome his lifelong regret of not having done more experimental stuff at university. Would he have had the patience to handle all the bullshit of the physical word without going back to the informational sciences? Maybe, maybe not. But now he will probably never know?!
Notice the orange high visibility cycling jersey under the lab coat, from someone who had just ridden in from work as fast as possible as part of his "lunch break". It is more fun when it is hard.
Scribe Jean Miélot, 15th century
. Ciro Santilli fantasizes that he would have make a good scribe in the middle ages, partly due to his self diagnosed graphomania, but also appreciation for foreign languages, and his mild obsession with the natural sciences.
OurBigBook.com is Ciro's view of a modern day scriptorium, except that now the illuminations are YouTube videos.
Chill and eat your bread in peace comes to mind. A scribe, in a library, reading and writing the entire day in peace and quiet. The life!
The job of a Internet-age scribe is basically that of making knowledge more open, legally extracting it from closed copyrighted sources, and explaining your understanding of it to the wider world under Creative Commons licenses on the web. And in the process of greater openness, given a well organized system, we are able combine the knowledge of many different people, and thus make things more understandable than any single/few creator closed source source could ever achieve.
Ciro once saw some cartoon on Wikipedia help pages of a turtle with a book in one hand, and typing into Wikipedia on its computer, TODO find it. That cartoon summarizes well the modern scribe life.
Another analogous version of this fantasy more in touch with Ciro's sinophily is the ideal of the Chinese scholar, notably including their stereotypical attributes such as mastery of the Four arts.

It's an open source note taking system that can publish from lightweight markup files in your computer both to a multi-user mind melding dynamic website, or as a static website. It's like Wikipedia + GitHub + Stack Overflow + Obsidian mashed up. Source code: github.com/ourbigbook/ourbigbook.
Sponsor me to work on this project. For 200k USD I will quit my job or not get a new job and work on OurBigBook full time for a second year to try and kickstart The Higher Education Revolution. Status: ~44k / 200k USD. At 2M USD I retire and work on open STEM forever. How to donate: Section "Sponsor Ciro Santilli's work on OurBigBook.com".
I first quit my job 1st June 2024 to work on the project for 1 year after I reached my initial 100k goal mostly via a 1000 Monero donation. For a second follow up year, I increased my requirement to 200k USD to give me more peace of mind. So the total donation so far is 144k, and if I reach a total of 300k USD, then I'll work on the project for a second year. A second year greatly improve chances of success: year one I improved my tech, year two I come guns blazing to solve courses and expand further.
Mission: to live in a world where you can learn university-level mathematics, physics, chemistry, biology and engineering from perfect free open source books that anyone can write to get famous. More rationale: Section "OurBigBook.com"
Explaining things is my superpower, e.g. I was top user #39 on Stack Overflow in 2023[ref][ref] and I have a few 1k+ star educational GitHub repositories[ref][ref][ref][ref]. Now I want to bring that level of awesomeness to masters level Mathematics and Physics. But I can't do it alone! So I created OurBigBook.com to allow everyone to work together towards the perfect book of everything.
My life's goal is to bring hardcore university-level STEM open educational content to all ages. Sponsor me at github.com/sponsors/cirosantilli starting from 1$/month so I can work full time on it. Further information: Section "Sponsor Ciro Santilli's work on OurBigBook.com". Achieving what I call "free gifted education" is my Nirvana.

Besides that, I'm also a freedom of speech slacktivist and recreational cyclist. I like Chinese traditional music and classic Brazilian pop. Opinions are my own, but they could be yours too. Tax the rich.
Let's create an educational system with:
- no distinction between university and high school, students just go as fast as they can to what they really want without stupid university entry exams
- fully open source learning material
- on-demand examinations that anyone can easily take without prerequisites
- granular entry selection only for space in specific laboratories or participation in specific novel research projects
I offer:
- online private tutoring for:
- any STEM university course
- passionate younger STEM students (any age) who want to learn university level material and beyond. Can your kid be the next Fields Medalist or Nobel Prize winner? I'm here to help, especially if you are filthy rich! I focus moving students forward as fast as they want on and on producing useful novel tutorials and results
Let your child be my Emile, and me be their Adolfo Amidei, and let's see how far they can go! I will help take your child:and achieve their ambitious STEM goals!- into the best universities
- into the best PhD programs
- educational consulting for institutions looking to improve their STEM courses
- do you know that course or teacher that consistently gets bad reviews every year? I'll work with the teacher to turn the problem around!
- are you looking to create a consistent open educational resources offering to increase your institutions internationally visibility? I can help with that too.
My approach is to:For minors, parents are welcome to join video calls, and all interactions with the student will be recorded and made available to parents.
- propose interesting research projects. The starting point is always deciding the end goal: Section "Backward design"
- learn what is needed to do the project together with the student(s)
- publish any novel results or tutorials/tools produced freely licensed online, and encourage the student to do the same (Section "Let students learn by teaching", digital garden)
I have a proven track of explaining complex concepts in an interesting and useful way. I work for the learner. Teaching statement at: Section "How to teach". Pricing to be discussed. Contact details at: Section "How to contact Ciro Santilli".
I am particularly excited about pointing people to the potential next big things, my top picks these days are:I am also generally interested in:
- quantum computing
- AGI research, in particular AI code generation, automated theorem proving and robotics
- assorted molecular biology technologies
- 20th century physics, notably AMO and condensed matter
- the history of science, and in particular trying to look at seminal papers of a field

Artist unknown, uploaded December 2014. Part of Section "Cool data embedded in the Bitcoin blockchain" where Ciro Santilli maintains a curated list of such interesting inscriptions.
This was a small project done by Ciro for artistic purposes that received some attention due to the incredible hype surrounding cryptocurrencies at the time. Ciro Santilli's views on cryptocurrencies are summarized at: Section "Are cryptocurrencies useful?".
YellowRobot.jpg
JPG image fully embedded in the Bitcoin blockchain depicting some kind of cut material art depicting a yellow robot, inscribed on January 29, 2017.
Ciro Santilli found this image and others during his research for Section "Cool data embedded in the Bitcoin blockchain" by searching for image fingerprints on every transaction payload of the blockchain with a script.
The image was uploaded by EMBII, co-creator of the AtomSea & EMBII upload mechanism, which was responsible for a large part of the image inscriptions in the Bitcoin blockchain.
The associated message reads:This is one of Ciro Santilli's favorite AtomSea & EMBII uploads, as it perfectly encapsules the "medium as an art form" approach to blockchain art, where even non-novel works can be recontextualized into something interesting, here depicting an opposition between the ephemeral and the immutable.
Chiharu [EMBII's Japanese wife] and I found this little yellow robot while exploring Chicago. It will be covered by tar or eventually removed but this tribute will remain. N 41.880778 E -87.629210
At twitter.com/EMBII4U/status/1615389973343268871 EMBII announced that he would be giving off shares of that image on Sup!?, a Bitcoin-backed NFT system he was; making. In December 2023, he gave some shares of the robot to Ciro Santilli.
2010 Wayback Machine archive of starwarsweb.net
. This website was used as one of the CIA 2010 covert communication websites, a covert system the CIA used to communicate with its assets. More details at: Section "CIA 2010 covert communication websites".
Ciro Santilli had some naughty OSINT fun finding some of the websites of this defunct network in 2023 after he heard about the 2022 Reuters report on the matter, which for the first time gave away 7 concrete websites out of a claimed 885 total found. As of November 2023, Ciro had found about 350 of them.
2010 Wayback Machine archive of noticiasmusica.net
. This is another website that was used as one of the CIA 2010 covert communication websites. This website is written in Brazilian Portuguese, and therefore suggests that the CIA had assets in Brazil at the time, and thus was spying on a "fellow democracy".
Although Snowden's revelations made it extremely obvious to the world that the USA spies upon everyone outside of the Five Eyes, including fellow democracies, it is rare to have such a direct a concrete proof of it visible live right on the Wayback Machine. Other targeted democracies include France, Germany, Italy and Spain. More details at: USA spying on its own allies.

- GitHub makes Ciro feel especially naughty:
- All GitHub Commit Emails: he extracted (almost) all Git commit emails from GitHub with Google BigQuery
Figure 1. All GitHub Commit Emails repo before takedown. Screenshot from archive.is. - A repository with 1 million commits: likely the live repo with the most commits as of 2017
- An 100 year GitHub streak, likely longest ever when that existed. It was consuming too much server resources however, which led to GitHub admins manually turning off his contribution history.

The eye in Ciro Santilli's website banner by
Ciro Santilli 35 Updated 2025-03-28 +Created 1970-01-01
Ciro was trying to make his face fit on the banner. But it is hard because faces are square and text is long.
Then at one point, the CSS was a bit broken and the eye stuck out just left of Ciro Santilli.
At this moment, Ciro knew what to do.
This produced a "continuous image symbol to text" effect that felt so right.
The concept, like any other, is not in itself new and has been used by others, Ciro just independently rediscovered it again:
