Electrical impedance Updated 2025-07-16
Ciro Santilli distinctly remembers being taught that at basic electrical engineering school during Ciro Santilli's undergrad studies at the University of São Paulo.
It really allows you to do alternating current calculations much as you'd do DC calculations with resistors, quite poweful. It must have been all the rage in the 1950s.

Elis Regina Updated 2025-07-16
Mostly interpreter of songs written by others. But she's just too amazing, many of her interpretations are better than the original.
God, even Ciro Santilli is slightly shocked by her death, which happened before he was born, can you imagine it at the time? She was MPB's golden girl...

Respect on the technical side by Ciro Santilli.
But the way he treated his first wife Justine Musk, is very very weird, incomprehensible: www.marieclaire.com/sex-love/a5380/millionaire-starter-wife/
Positive Cirocoins for possibly going to reverse Twitter's unfair Trump ban if his Twitter acquisition goes through:

Encyclopedia Britannica Updated 2025-07-16
Genius: Richard Feynman and Modern Physics by James Gleick (1994) mentions several times how Richard Feynman was a reader of the encyclopedia. E.g. in youtu.be/ivxkd98mDvc?t=50 Richard's sister also talks about it.
Then the Internet came along and killed it.
The motivation model for collaborators was simple: to get famous. To be able to be selected contribute an article meant that you knew something or two! There was some physicist Ciro read the biography of who was really glad to be able to write an article on the encyclopedia after having worshiped it for so long, TODO find the reference.
While this is somewhat a part of Wikipedia motivation, it is much less so because there is no single article authorship. This is something OurBigBook.com aims to improve.
Enrico Fermi Updated 2025-07-16
Died of cancer at age 53. Ciro Santilli just can't help but speculate that it is linked to radioactivity exposure.
Enter through the narrow gate Updated 2025-07-16
Gospel of Matthew 7:13:
Enter through the narrow gate. For wide is the gate and broad is the road that leads to destruction, and many enter through it.
Ciro Santilli really likes this one, because he feels that where many people go, it is useless to go again. It is much better to explore that which few can do, but which many will need.

Epic Rap Battles of History Updated 2025-07-16
Most of the videos are crap, but the following ones almost killed Ciro Santilli of laughter:
- Video "Bill Gates vs Steve Jobs by Epic Rap Battles of History (2012)"
- Video 1. "Rasputin vs Stalin by Epic Rap Battles of History (2013)"
Rasputin vs Stalin by Epic Rap Battles of History (2013)
Source. See also: cirosantilli.com/china-dictatorship/stalin.Monty Python has a few precursors to the "random famous people mixed together compting" format, although not in the rap fight format:
Communist Quiz by Monty Python (1970)
Source. Has a Wiki page: en.wikipedia.org/wiki/World_Forum/Communist_Quiz. Brings to mind: Video "Football, Football, Football by Mitchell and Webb".Philosophers' Football Match by Monty Python (1972)
Source. If you can understand the jokes, your philosophy level is pretty good. Like more than zero. Wiki page: en.wikipedia.org/wiki/The_Philosophers%27_Football_Match. Ciro loves how that page currently uses a standard footbal match template to describe the match! Epic Stack Overflow users Updated 2025-07-16
These are some users Ciro Santilli particularly respects, mostly due to their contributions to systems programming subjects:
- unix.stackexchange.com/users/885/gilles-so-stop-being-evil
- stackoverflow.com/users/379897/r-github-stop-helping-icea
- stackoverflow.com/users/196561/osgx
- stackoverflow.com/users/50617/employed-russian Employed Russian. Binutils, ELF, GDB, claims to work at Google. The only Russian sounding name on GDB and Binutils git log is that of Paul Pluzhnikov: www.linkedin.com/in/paul-pluzhnikov-61b9676/ and Employed Russian mentions one of his commits at: stackoverflow.com/questions/3718072/gdb-takes-too-long-and-ctrl-c-has-no-effect Ex physicist: www.researchgate.net/profile/Paul_Pluzhnikov
Ciro also really likes the following users, a bit less like Gods, and bit more like friends:
- partly because they were close by on the yearly reputation charts for a long time circa 2020, so it feels like they also focus on replying to important questions rather than answering new duplicates immediately:
- stackoverflow.com/users/642706/basil-bourque: GCC dev, but started replying lots of Java questions as of 2021 it seems for some reason
- stackoverflow.com/users/541136/aaron-hall: Python, NixOS and Haskell more and more it seems. Also pro freedom of speech, gotta love those religious liberal Republicans. Reminds Ciro of Ron Maimon very slightly, maybe it's just the New Yorkedneess. Ciro once met another intelligent dude who liked both Haskell and NixOS, there must be some correlation.
- VonC: Git God, VonC is just Super nice, gives clear credit to others, always positive interactions. Love this dude. Twitter: twitter.com/VonC_. He was the one that held the Necromancer record in 2019 before Ciro took it.
- Peter Cordes. An assembly maniac this one. And a really nice one too. Sometimes pedantic, but always nice, and always correct. He's been going into God level more and more it must be said:
Other interesting people:
- stackoverflow.com/users/560648/lightness-races-in-orbit Lightness Races in Orbit. C++ God. Interesting aesthetics. Real name: Tom Lachecki, British, as per:As of 2023 marked "retired" from Stack Overflow, rep graph suggests since 2020.
- stackoverflow.com/users/3681880/suragch the number 3 necromancer dude. But then in 2022 he found God and mostly quit: suragch.medium.com/programming-was-my-god-89b625164a69

Ahh, this dude is just like Ciro Santilli, trying to create the ultimate natural sciences encyclopedia!
Europe Updated 2025-07-16
For the most part, a great pseudo-country to live in with lots of cultural diversity, art and safety.
However, Europe is in economic decline after all its Jewish and German geniuses fled in/after World War II and due to having more than one natural language is bad for the world.
Ciro Santilli moved to Europe in 2010.
Exam as a service 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.
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.

Exascale hypothesis 2025-07-26
The "exascale hypothesis" is a name made up by Ciro Santilli to refer to the hypothesis that the real-time human brain simulation becomes possible at exascale computing.
It is a simple extrapolation from the number of synapses in the human brain () times the number of times each neuron fires per second.
Excessive encapsulation is the root of much evil Updated 2025-07-16
Some anecdotes.
Ciro Santilli never splits up functions unless there is more than one calling point. If you split early, the chances that the interface will be wrong are huge, and a much larger refactoring follows.
int cross_block_var;
// First step.
{
int myvar;
}
// Second step.
{
int myvar;
}Ciro has seen and had to deal with in his lifetime with two projects that had like 3 to 10 git separate Git repositories, all created and maintained by the same small group of developers of the same organization, even though one could not build without the other. Keeping everything in sync was Hell! Why not just have three directories inside a single repository with a single source of truth?
Another important case: Linux should have at least a C standard library, init system, and shell in-tree, like BSD Operating Systems, as mentioned at: Section "Linux".
Express.js Updated 2025-07-16
This doesn't do a hole lot. Ciro Santilli wouldn't really call it a web framework. It's more like a middleware. Real web frameworks are built on top of it.
Examples under: nodejs/express:
- nodejs/express/min.js: minimal example. Visit localhost:3000 and it shows
hello world. It is a bit wrong because the headers say HTML but we return plaintext. - nodejs/express/index.js: example dump with automated tests where possible. The automated tests are run at startup after the server launches. Then the server keeps running so you can interact with it.
Fabrice Bellard Updated 2025-07-16
Creator of QEMU and FFmpeg, both of which Ciro Santilli deeply respects. And a bunch other random stuff.
What is shocking about Fabrice this is that both are insanely important software that Ciro Santilli really likes, and both seem to be completely unrelated subjects!
Google made billions on top of this dude:
- FFmpeg is the backend of YouTube
- QEMU is the default emulator for Android Studio as of 2019, which Android developers use by default under the hood to develop Android Apps on their desktop without the need for a real device.
At last but not least, Fabrice also studied in the same school that Ciro Santilli studied in France, École Polytechnique.
It is a shame that he keeps such a low profile, there are no videos of him on the web, and he declines interviews.
Another surprising fact is that Fabrice has not worked for the "Big Tech Companies" as far as can be publicly seen, but rather mostly on smaller companies that he co-founded: www.quora.com/Computer-Programmers/Computer-Programmers-Where-is-Fabrice-Bellard-employed
And he's also into some completely random projcts unsurprisingly:
