Ciro Santilli Updated 2026-08-21
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.
- laptop: high end Lenovo ThinkPad
- distro: latest Ubuntu release
- Vim or Emacs: vi/vim. But for The Love, will someone please make an open source C++ integrated development environment that actually just works?
- 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?
- QWERTY or Dvorak: QWERTY, alas
- birth name: Ciro Duran Santilli
Other people with the same name are listed at Section "Ciro Santilli's homonyms".
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.
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.
