Ciro Santilli @cirosantilli 34

In the year 2000, Ciro lived with his parents for 10 months in the Coventry because his father took some courses at the University of Warwick. This was Ciro's most important educational experience, more so than any other inCiro Santilli's formal education, because it taught him the Holy Language of English, which infinitely expanded Ciro's Internet horizons, and shaped Ciro's having more than one natural language is bad for the world philosophy. When he came back to Brazil, Ciro skipped dozens of levels in his English school in Santos, São Paulo, Brazil, a Brazilian chain called Cultura Inglesa, and was put to study with much older teenagers who marveled at Ciro's incredibly cute, but since lost, British accent.

Another huge advantage of Coventry is that the Hearsall Community Primary School where Ciro studied was a regular British primary school but with two classes dedicated to foreign students to learn English before integrating with the British students. There were a several kids from Kosovo there due to the Kosovo War which was just ending, and it was there that Ciro made his first Chinese friend, yet unaware of course of the role the country would later play in his life. One particularly fun memory was that of playing soccer on the school playground with a sponge ball to avoid breaking the windows. Then one day it was raining, british weather of course, but Ciro still went for a header, and the soaked sponge ball was soaked and splashed Ciro with dirty water all over. Good days.

Ciro also played a bit of Rugby in those days in a local club.

Some other good memories are of reading the first two Harry Potters, playing and mostly watching other kids play Pokemon on their Game Boys and Pokemon trading cards, and going to a nearby commons playing field and woods, as it typical throughout the UK. Ciro also played some rugby with a local boys team TODO name? but for some reason his team was always crushed when they went to nearby towns to play against other teams. And Ciro also went with his family or with school to some nearby attractions, like Stratford-Upon-Avon (Shakespeare's hometown), and some castles.

Maybe Ciro Santilli should do something useful and remarkable so that someone might actually want to read his biography in the first place. But hey, procrastination.

Ciro Santilli was born in Brazil in the small/medium city of Rio Claro, São Paulo (~200k people in 2020) in the State of São Paulo in 1989 AD.

The family then moved to Jundiaí in 1995, and then finally to Santos, São Paulo, Brazil in 1997.

At the age of 10, Ciro Santilli spent 10 months in Coventry, United Kingdom, where he greatly improved his English.

After Coventry, Ciro's family went back to Santos, São Paulo, Brazil, which made a deep impression on Ciro, until he Ciro Santilli's undergrad studies at the University of São Paulo in 2007.

In 2010, as mentioned atSection "Ciro Santilli's formal education", Ciro as admitted in a double degree program at the École Polytechnique, France, where he stayed until 2013. Going to France was a mind blowing, life changing event.

When Ciro was a teenager, he was extremely cheap e.g. for clothes, food and video games even tough his family didn't have bad financial conditions.

This was mostly to save the world by not wasting resources that other people in need could use, and to save money so he could have more money to do more of whatever he wanted without the obligation to work.

But Ciro admits that shocking people with the incredible level of low quality goods was also fun.

Ciro changed after he came to Europe, especially in regards to food, perhaps corrupted by the fact that now the best chocolates, cheeses and breads in the world were not much more expensive than the cheapest brand you could buy. He still hates clothes that are just to look good like costumes though.

Living close to a small favela, São Remo, the favela next to USP, helped Ciro get frighteningly cheap goods on the shop frequented by the favela neighbours.

One legendary story is that of when his flatmate dropped some past on the kitchen floor, and the bowl broke, but Ciro prevented the flatmate from throwing it away and ate some of it nevertheless. What spooked them out the most was Ciro's statement that the pasta now had a crunchy glass shard texture to it.

If Achilles' had his heel, Ciro had his knee.

First during University in Brazil while trying a kick up during the development of Cirodance his knee went a bit weird for a few weeks.

Then, just after arriving in France for École Polytechnique, the boys were playing indoor soccer, and to impress the girls Ciro was playing really hard, even took off his shirt, and suddenly when he was running by himself his knee snapped, he fell and it hurt like hell.

Ciro was on crutches for a few weeks, but the inflammation went away, but then he tried to play more soccer, but the knee was not as stable as before, and once he tried to run full speed, it slipped and hurt him a bit more (less severely) and so he gave up. For some reason it was not visible on the tomography made at the hospital.

Maybe Ciro should have investigated more though, certainly an experienced doctor could have done a hand pressure exam to determine which joint was damaged manually even. That was a medical failure.

So from this day on Ciro gave up on all interesting sports, and confined himself to more repetitive stuff like gym weights and cycling: Section "Ciro Santilli's sport practice". At Polytechnique he was forced to take up swimming as his mandatory sport, that was unbearably boring.

This defect is likely genetic since a close relative had similar problems.

But oh well, his then not-even girlfriend was impressed enough by the soccer or sorry enough for the sucker to marry him, so it worked out.

When asked, Ciro likes to say that he speaks something between 1.5 and 3.5 languages in total, depending on how you count, because Portuguese, French and English are 99.99% the same, and Chinese is completely different but Ciro only knows about 50% of it if counted optimistically.

Firstly, in 2012, while he was at École Polytechnique, Ciro Santilli was introduced to LaTeX (thank God for French mathematical obsession), and his mind was blown:he though. Why isn't everyone doing that!

One particular event stood out: Ciro made a small change to his teacher's course material, who blessed be him (dude's a legend, Ciro just noticed he has some Chinese publications with another French dude, e.g. www.amazon.co.uk/高效算法-应试与提高必修128例-克里斯托弗-Christoph-Durr/dp/B078SJQPVK "High-efficiency algorithm competitions 128 examples", did he write it the Chinese himself?? Must be of course to complement the notoriously low French professor salaries), made it available, and then Ciro gave him back the .tex file. Ciro was just a bit worried about how the teacher would be able to tell what he had changed in the file to validate the change. The teacher just said of course, "no problem, I'll just use diff". Ciro had never heard of diff. Let alone Git of course, though yes, this was a bit early in Git's history version control systems had been around since forever of course. This was 2011 or 2012, about 4 or 5 years into a superior education curricula with various courses involving computers, some requiring quite a lot of "fill these empty functions" style programming. Education is a joke. Anyways, this was a prelude to exactly what Ciro wanted to do in OurBigBook.com. This might have been the one actually: webia.lip6.fr/~durrc/Iut/Notes580.pdf

Not long afterwards, Ciro started playing with Linux. Until then, Ciro had had some contacts with the mysterious operating system at university, and was a bit puzzled what the point of it was! He clearly remembers:University should be forced to use only open source software and hardware in undergrad teaching courses by law BTW.

Then came an Ubuntu live disk on his own machine, and finally a measly 40GB dual book partition in a Microsoft Windows machine on a laptop. At first, it took a lot of time to learn all the crazy new terminal stuff! Yes, at this point, Ubuntu was already usable enough without the terminal, an accomplishment actually. But as a programmer, Ciro felt obliged to learn. Many hours were spent reading man pages at the library. But it all just felt so right, and sometimes powerful... true wizardry.

And ten years later, Ciro was seriously considering buying a computer without Windows pre-installed. He had not used Windows a single tie on a personal machine even once in those ten years!

Finally, to finish things off Ciro found two websites that changed his life forever, and made be believe that there was an alternative: Stack Overflow and GitHub.

The brutal openness of it all. The raw high quality content. Ugliness and uselessness too no doubt. But definitely spark in a sea of darkness.

The "most prestigious French engineering school". Only 3 Nobels though as of 2019, the scientists are mostly at École normale supérieure (Paris). A gazillion CEOs ad politicians however.

Ciro Santilli studied there from 2010 to 2013.

Ciro considers him entering at Polytechnique a small miracle. First, on his second year of University in Brazil, he first had to fail to join the also good but not as good École centrales, which really annoyed him as he saw the "other good students" who wanted to go out get their wish. This also explains why there are so few students from his university going to Polytechnique in the late 2010's: most already went to other locations! Then, on his third year, he tried Polytechnique and got in despite feeling that the others who got in knew much more mathematics and physics than him. Rather, Ciro believes that he got in chiefly due to his intense passion for the sciences which he showed during the interview.

The miracle would have been even greater if it had happened in 2020. At this time, out of 10 Brazilians, 9 are from ITA, the "hardest to get into" university in Brazil, and also military like Polytechnique. Make no mistake, those students are amazing and deserve it without any doubt. But there is more to the story. It could be argued that many of them only go because they don't have any other choice of exchange program. Remember: Ciro had to fail applications on previous universities before getting into Polytech. Also, they don't get any Brazilian degree because ITA has no agreements with Polytechnique, and are therefore extremely likely to never come back. Not that Ciro thinks this is particularly bad for Brazil though, but it does make for a better deal for France overall as well. They also happen to have closer ties across cohorts of different years, and have managed to maintain a Google Doc with scanned past examinations (as of 2020 however, some/all of those examinations have been uploaded publicly, big kudos to them). Also almost all of them are software engineers, which is one of the few disciplines given at the relatively small ITA. This lack of diversity might not be ideal: if I were France, I would rather fish around all top Brazilian schools for "the best".

Besides the amazing funding/opportunities/alumni/staff loop which you can read about elsewhere, Polytechnique is amazing because you can choose what you will study every year to a very large extent.

This is in huge contrast to the crappy systems Ciro had seen e.g. in Brazil's Polytechnic School of the University of São Paulo, where students have to decide basically all their courses in huge packages, either at university entry (thus when they are completely clueless), or at a single point inside the university studies, changes being much harder.

Life quality was also amazing. Good free accommodation on campus and at the time a no-obligations scholarship for every foreign student great sport facilities. It seems that after Ciro left however more restrictions are added to the scholarships, what a shame! As of 2020 not everyone gets scholarships anymore it seems, mostly only loans that have to be paid back later. And those who are not poor have to pay Polytechnique scholarship fees on top of their living costs. And thus French austerity measures are undermining the greatest long term investment a country can possibly make: that of importing the very best students from other countries into yours. This after their host country has already spent 20 years raising and selecting them. And you won't even pay them 2 years of frugal existence to steal some of them them. Even if those students move away from your country later on, the contacts they made in your country mean they are much more likely to bring businesses over. But some will stay. Basically, France is becoming more like the United States.

This also makes it much more difficult for those students to do a PhD afterwards, where they would get paid very little, and are unable to pay their student debts. A PhD would be where they would possibly bring more of the next big thing to your country. Instead, they are much more likely to just go work for some big American company data wrangling and bring nothing to your country but their student debt dividends instead, which they will be pay to pay for in one year with those amazing salaries. And unsurprisingly many go to into banks. What a big time fail, France.

Sport was mandatory due to the military nature of the school. This did have the upside of getting students together more, although Ciro is against all forms of forced intellectual of physical activities for students. If you liked your sport it would be really cool though. But due to Section "Ciro Santilli's knee", he was forced to give up his first beloved choice which was soccer... life can be cruel. If only Ciro had known cycling at at the time, and if only that had been one of the sports you could choose (but of course it isn't, no school will want the bad reputation of when one of their students gets killed in a car accident).

There were also some useless "military exercises", or special situations in which you had to wear the useless school uniform as a formal "respect social clothing". Ciro Santilli is completely against all that meaningless bullshit, this his just a form of theatrical masturbation to nostalgically remember the good old days of Napoleon when France still ruled the world, and before they tortured the Algerians, see also: Video 4. "Gérard Fuchs interview from Ils racontent la Guerre d'Algérie (1982)". If you are going to do military-like stuff, then at least teach students how to shoot modern rifles and modern warfare tactics (which some of the French students actually do in the pre-school mandatory internship), and not this 18th century bullshit. Ciro favours of course the hoodie-wearing, "I only care about your abilities meritocracy" culture of Silicon Valley. And without the political correctness now associated with it in the 2020s. And no shooting people if possible.

During the time Ciro was at Polytechnique in early 2010's, the school was really isolated in the Plateau de Saclay, there were no shops in 10 minute walking distance! You either had to climb 300 steps to go down to the nearest village, Lozère, or take a bus to the nearest town, Massy. The fact that Times Higher Education ranked it as the second best university in the world in 2019 (archive) makes it good justice, given the small 500 student body. Things started to change a bit after Ciro left however, with the creation of the Polytechnic Institute of Paris, which is bringing other schools to the Lozere area. This is for the best, as it might improve the global rankings of Polytechnique. Also it is a waste to have so few students at a technopole. But it will reduce the mystique of the place. You can't have everything in life.

Before 1976, Polytechnique was actually in the center of Paris at the Latin Quarter, so the Lozère mystique is not a traditional thing. But even when in Paris, students were in theory restricted to school grounds a most of the time. Although there are famous stories of a certain tree that could be used to climb the fence to go to Parisian parties when they couldn't stand it anymore. The tree was somewhat intentionally overlooked by school administrators. Polytechnique was drawn to Saclay no doubt because of the gravity of the CEA Paris-Saclay, France's analog to the United States Department of Energy national laboratories.

This made for some good memories though. The isolation favored concentration, and gave the place a mystical feeling. And then when you went to eat amazing Chinese food in Paris it just felt even more special and magic since you were so limited during the week. It was also under those magical circumstances in which Ciro met his wife, another student of the school, see also: Section "The main function of university is sexual selection".

Ciro also agonized about passing courses to get useless grades though! Polytechnique is hard for most Brazilians, specially if you select the more mathematics oriented courses, because the French students were math brainwashed for two years before joining.

Ciro's favorite spots/activities:

The following promotional videos give an idea of how the school looks like, although they fundamentally miss the little corners that Ciro really loved in that the place and which made it magic:

And a one second Ciro Santilli appearance from a 2016 video made during the annual Brazilian barbecue (or as close as you an get to it) which many ex-Brazilian students attend able: www.youtube.com/watch?v=ndX_-A2Rjpo&t=189 wearing a Ring t-shirt.

The name is a bit obscure if you don't think in very generalized terms right out of the gate. It refers to a linear polynomial of multiple variables, which by definition must have the super simple form of:and then we just put the unknown $y$ and each derivative into that simple polynomial:except that now the $c_i$ are not just constants, but they can also depend on the argument $x$ (but not on $y$ or its derivatives).

Explicit solutions exist for the very specific cases of:

Although Ciro Santilli lived in São Paulo City nominally during his studies, it would be more precise to say that he lived in University of São Paulo-land, because Ciro was cheap, didn't have a car, and did nothing but study, stay at home, go back to Santos to see his parents and the beach.

But the little he saw of the city made a deep impression on him.

The unreasonable size.

The unbearable contrasts.

Caetano's Sampa is the ultimate description of the city!

As of 2020, university has the following very important applications:Notably, education is an IQ test, not a way to learn useful and beautiful things.

One major issue is that teachers don't have the right incentive to, nor are selected to, teach well. Thus the existence of Rate My Professors! But we can do better...

Which is why Ciro Santilli wants to destroy its current format with OurBigBook.com. He believes that we can find a more efficient organization to achieve both the social and research functions of university, by first doing as much as possible online

Ciro's university experiences are mentioned at: Ciro Santilli's formal education.

Ciro Santilli is against affirmative action university entry quotas that reserve spaces e.g. for students from discriminated races or poor families. Instead, he believes that affirmative action should take place on earlier stages of education as described at: free gifted education.

Notably, Brazil has implemented a very heavy university entry quota system after Ciro had left university there: www.bbc.co.uk/news/business-23862676

This is of course easy for a white male from a privileged background to say, and infinite debate has already been had on this matter, but here goes again.

First, in defense to the personal attack, Ciro raises the fact that he has dedicated large chunks (all?) of his life to open source software and knowledge in general, which Ciro believes is the only way to actually make the world fairer to poor countries. His money (time) is where his mouth is.

One good argument in favor of the Brazilian quota system, is that the kids who enter university because of quotas do just as well as those who don't.

Ciro has actually believes that this is possible, and offers the following possible explanation: most of pre-university knowledge is useless, and university selection system is crap, and Ciro wants to destroy it with a system in which anyone can learn university stuff from home.

Both the top end of the quota and non-quota kids are basically equally capable of doing useful stuff therefore.

Only a tiny fraction of what you learn in high school is useful for university or your career.

And possibly more importantly than knowledge, Ciro saw many of his colleagues (basically all of which were from relatively privileged backgrounds) "do badly" in university, because of lack of motivation, because they had chosen a course only to find that they were not interested in it because the existing high school educational system is crap and does not help them find what they love and because it costs you several years of your life to change your choice in most universities (long live École Polytechnique).

Maybe the fact that poor kids know that they are fucked if they fail, and so they have to succeed at any cost, might also help with motivation. Which is a terrible terrible thing, because only those who have to leeway to take risks end up taking them and making the the next big thing.

Ciro believes instead that only once kids have learnt university level stuff in their area of interest for free on the Internet should they go through selection based on that specific and much more concentrated useful knowledge.

And this competition must only be used to distribute resources which you can't learn from fucking computers:

Once this point knowledge is reached however, it starts to become unclear if a single "everyone takes the same test to avoid discrimination" test is feasible anymore, and we start entering the much more relevant (and potentially discriminatory) "I am a teacher trying to advance the state of the art, and I need a person mildly skilled in the art to do some slave labor for me", which is PhDs selection work.

If quota are in place, what will happen is that parents of the rich kids will start investing less in education, and possibly just put their kids in high schools, and do home schooling instead. This would therefore reduce the total investments the country makes in education!

Outside of the obvious technical evolution proposed, Ciro is a huge proponent of free gifted education. Or closely related, creating scholarships that focus on poor students. The entry requirements should be the same, but once you qualify, everyone should have enough money to lead a decent life during their studies.

Then let those kids pass exactly the same university entry exams, and watch them crush the average privileged kids.

This advice is similar to what is mentioned at: what poor countries have to do to get richer. When you don't have money to do everything, you must select a few good bets and focus on them. You can't pay a lot to every public school teacher, so you must select a few select places that need it the most. As those smart bets pay off, you start to have more and more money to expand the system further.

Ciro Santilli studied there for a few years starting in 2007.

In retrospect, doing electrical engineering (and likey the other engineering degrees) felt like taking a trip to the 60s in the United States, due to both the subject matter, and how old the concrete buildings were!

This does not need to be a bad thing. It is in that era (and earlier) that much of the exciting foundations of the field were set, and there is great value in there is value in tutorials written by early pioneers of the field. Not that they were amazing at excting history lessons as they should be. But the course outline suggested that intent.

But that point of view must also be accompanied by the excitement of the great ongoing advances of technology (and impact they had in the past). And on that, they failed.

One day, one day, we will fix that.
