Title reply because they can't Ctrl+F: How Ciro Santilli manages to write so much
Most of the thread went into pro/anti gay trashtalk due to Ciro using Gay Putin at the time on his Stack Overflow profile as a useless way to protest the Russian invasion of Ukraine.
Some comments:
How does this guy manage to be so active on Stack Overflow? I feel like this disgusting avatar is on at least a quarter of all the active posts.
The answers are always pretty good though.
I came across this schizo's github once, but I had forgotten his name
Obviously severe autism. Also racism homophobia Looks like everything is ok if it's Russia/Chinese...
Reply: it is publicly known that Putin is homophobic as fuck and hates that picture. Therefore we use it. If Putin were heterophobic, we'd post him as hetero.
The only new information:
Reminds me of Xah Lee.
The eye in Ciro Santilli's website banner by Ciro Santilli 35 Updated +Created
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:
Ciro Santilli's website is not mobile friendly by Ciro Santilli 35 Updated +Created
True art cannot be consumed in mobile format.
Motivation by Ciro Santilli 35 Updated +Created
Many subjects have changed very little in the last hundred years, and so it is mind-blowing that people have to pay for books that teach them!
If computers are bicycles for the mind, Ciro wants this website to be the Ferrari of the mind.
Since Ciro Santilli was young, he has been bewildered by the natural sciences and mathematics due to his bad memory.
The beauty of those subjects has always felt like intense sunlight in a fresh morning to Ciro. Sometimes it gets covered by clouds and obscured by less important things, but it always comes back again and again, weaker or stronger with its warmth, guiding Ciro's life path.
As a result, he has always suffered a lot at school: his grades were good, but he wasn't really learning those beautiful things that he wanted to learn!
School, instead of helping him, was just wasting his time with superficial knowledge.
First, before university, school organization had only one goal: put you into the best universities, to make a poster out of you and get publicity, so that more parents will be willing to pay them money to put their kids into good university.
Ciro once asked a chemistry teacher some "deeper question" after course was over, related to the superficial vision of the topic they were learning to get grades in university entry exams. The teacher replied something like:
You remind me of a friend of mine. He always wanted to understand the deeper reason for things. He now works at NASA.
Ciro feels that this was one of the greatest compliments he has ever received in his life. This teacher, understood him. Funny how some things stick, while all the rest fades.
Another interesting anecdote is how Ciro Santilli's mother recalls that she always found out about exams in the same way: when the phone started ringing as Ciro's friends started asking for help with the subjects just before the exam. Sometimes it was already too hopelessly late, but Ciro almost always tried. Nothing shows how much better you are than someone than teaching them.
Then, after entering university, although things got way better because were are able to learn things that are borderline useful.
Ciro still felt a strong emotion of nostalgia when after university his mother asked if she could throw away his high school books, and Ciro started tearing them all down for recycling. Such is life.
University teachers were still to a large extent researchers who didn't want to, know how to and above all have enough time and institutional freedom to teach things properly and make you see their beauty, some good relate articles:
The very fact that you had very little choice of what to learn so that a large group can get a "Diploma", makes it impossible for people to deeply learn what the really want.
This is especially true because Ciro was in Brazil, a third world country, where the opportunities are comparatively extremely limited to the first world.
Also extremely frustrating is how you might have to wait for years to get to the subject you really want. For example, on a physics course, quantum mechanics is normally only taught on the third year! While there is value to knowing the pre-requisites, holding people back for years is just too sad, and Ciro much prefers backward design. And just like the university entry exams, this creates an entry barrier situation where you might in the end find that "hey, that's not what I wanted to learn after all", see also: students must have a flexible choice of what to learn.
We've created a system where people just wait, and wait, and wait, never really doing what they really want. They wait through school to get into university. They wait through university to get to masters. They wait through masters to get to PhD. They wait through PhD to become a PI. And for the minuscule fraction of those that make it, they become fund proposal writers. And if you make any wrong choice along the, it's all over, you can't continue anymore, the cost would be too great. So you just become software engineer or a consultant. Is this the society that we really want?
And all of this is considering that he was very lucky to not be in a poor family, and was already in some of the best educational institutions locally available already, and had comparatively awesome teachers, without which he wouldn't be where he is today if he hadn't had such advantages in the first place.
But no matter how awesome one teacher is, no single person can overcome a system so large and broken. Without technological innovation that is.
The key problem all along the way is the Society's/Government's belief that everyone has to learn the same things, and that grades in exams mean anything.
Ciro believes however, that exams are useless, and that there are only two meaningful metrics:
  • how much money you make
  • fame for doing for doing useful work for society without earning money, which notably includes creating new or better free knowledge such as in academic papers, either novel or review
Even if you wanted to really learn natural sciences and had the time available, it is just too hard to find good resources to properly learn it. Even attending university courses are hit and miss between amazing and mediocre teachers.
If you go into a large book shop, the science section is tiny, and useless popular science books dominate it without precise experiment descriptions. And then, the only few "serious" books are a huge list of formulas without any experimental motivation.
And if you are lucky to have access to an university library that has open doors, most books are likely to be old and boring as well. Googling for PDFs from university courses is the best bet.
Around 2012 however, he finally saw the light, and started his path to Ciro Santilli's Open Source Enlightenment. University was not needed anymore. He could learn whatever he wanted. A vision was born.
To make things worse, for a long time he was tired of seeing poor people begging on the streets every day and not doing anything about it. He thought:
He who teaches one thousand, saves one million.
which like everything else is likely derived subconsciously from something else, here Schindler's list possibly adapted quote from the Talmud:
He who saves the life of one man saves the entire world.
So, by the time he left University, instead of pursuing a PhD in theoretical Mathematics or Physics just for the beauty of it as he had once considered, he had new plans.
We needed a new educational system. One that would allow people to fulfill their potential and desires, and truly improve society as a result, both in rich and poor countries.
And he found out that programming and applied mathematics could also be fun, so he might as well have some fun while doing this! ;-)
So he started Booktree in 2014, a GitLab fork, worked on it for an year, noticed the approach was dumb, and a few years later started building this new version. The repo github.com/booktree/booktree is a small snapshot of Ciro's 2014 brain on the area, there were quite a few similar projects at the time, and most have died.
Ciro is basically a librarian at heart, and wants to be the next:

Grading scale stoles from a Goolge interview by Ciro Santilli 35 Updated +Created
10You literally have written a book.
7 - 9Expert, go-to person on this technology.
5 - 6Solid daily working knowledge. Highly proficient.
3 - 4Comfortable working with this, have to check manual on some things.
1 - 2Have worked with it previously but either not much, or rusty.
I copied this grading scale mechanism from a failed Google interview ;-)
One problem with it is that I am always very hesitant to put a 5 on anything, who can not look at the documentation?
It is also hard to scope things right. Who can claim to be a C++ or Linux kernel expert, even if you wrote a book about it, since those are such humongous topics?
As a result, I haven't updated this in a while, and things may be out of date.
If your project does something that interests me, I can what it takes to contribute. Tell me what I must know, how long I have to learn it, and I'll call you back when I've mastered it.
Unmigrated sections of the old version of Ciro Santilli's website by Ciro Santilli 35 Updated +Created
It is interesting to see how your own ideas shift with time, and Ciro Santilli doesn't think the following are very important anymore, so he was lazy to migrate them.
When he did the original website Ciro was in a "I must show off my skills to get a job mindset", but then after he landed a few jobs he moved to a "CV websites are useless, just do amazing projects and showcase them on your website to help them succeed" mindset.

Ciro Santilli's love advice by Ciro Santilli 35 Updated +Created
In the field of Love and Friendship, Ciro is a big believer in the merciless application of tit for tat. Never desire someone's love if you give and what comes back is not proportional. Cut your attempts to reach out immediately in such cases.
Never tell a woman you like her before she is in your bed.
If someone likes you and you don't like them as much, make that clear to them. Don't put this off, be it for compassion, curiosity, loneliness, or narcissism.
youtu.be/Sb0VHGnhX4M?t=174 from Video "Charles Bukowski Scandanavian TV interviews":
The way to get a woman is not to have money, not to look nice, not to have a nice personality. The way to get a woman, is to always be available, night or day. Any time you phone, you're there, or you're at the bar. They know that you are available at all times. It is very, very important to a woman.
Cirocoin by Ciro Santilli 35 Updated +Created
Good pious Cirists earn Cirocoins.
Cirocoins are the most valuable form of currency that exists at any point.
Cirocoins can only be issued by Ciro Santilli.
Cirocoins are strictly nominal, and cannot be traded by recipients with anyone but Ciro, i.e. they are extremely illiquid.
Cirocoins can be removed from recipients at any point if they commit non-Cirist acts.
It is not possible to give a precise number to how many Cirocoins anyone owns. This is decided on a transaction by transaction basis. Ciro can therefore only inform you if your Cirocoin balance increased or decreased, but any attached number has no value, and thus are equivalent to expressions of type "you gained/lost a Cirocoin".
The following inferior currencies come to mind:
Social media as a public utility by Ciro Santilli 35 Updated +Created

Rooting for sport teams is stupid by Ciro Santilli 35 Updated +Created
Since Ciro Santilli is Brazilian, this is understandably a common conversation opener.
And rightly so, since soccer in particular is truly ridiculously popular in Brazil, where "what is your local soccer team?" is just as valid a conversation starter as "Which city are you from?".
So here goes Ciro's 2020 cynic answer:
I currently root actively against Brazil.
The ironic reason is simple: maybe is Brazil loses more on this useless art, then maybe people will get tired of it, and instead invest on more useful and beautiful arts.
Notably, what Ciro really wants people to root for are:
  • the number of Brazilian Nobel Prizes, which is zero, yes, zero, as of 2020, despite a population of 210 million people. But thank God for our one Field Medal, what an epic start, even though Mathematics is useless.
  • the number of high tech companies that have a global impact, which is likely extremely low as of 2020, and must contain only a few mammoths that dominate some local commodity market and therefore got enough money from that to expand a bit of technology worldwide. But they were mostly not classic tech startups that did world innovation from the start.
  • how low your country's Gini coefficient is
Don't get Ciro wrong.
Observing professionals who do it amazingly can be beautiful.
But why the F do you have to root for a team unless your wife or children are playing in it (and even then..., how will that help?)?
What will you get from that?
Even if it is your national team, why does it matter if they win or lose?
Hooliganism just takes that uselessness to a hole new level.
Now some confessions.
A five year old Ciro will never forget when the feeling of Brazil won the 1994 World Cup on the penalties and everyone went mad that evening.
A nine year old Ciro stopped watching the 1998 World Cup Final of Brazil vs France half way during the 3-0 massacre and went to his front garden to kick his soccer ball on the metallic fence gate which represented a goal.
After that, Ciro went through puberty he guesses, and noticed that the natural sciences are just cooler than this soccer watching bullshit.

How to diagnose a genius by Wilhelm Ostwald (1909) by Ciro Santilli 35 Updated +Created
www.nature.com/articles/081121a0. paywalled after more than 100 years, thanks Nature.
From the abstract:
Much money, his student went on to say, is spent by various Governments in attempting to discover those people whose thorough education may be expected to bring in a return of value to the State, and the question how best to discover latent genius is an eminently practical one. After cogitation, Prof. Ostwald came to the conclusion that it is those students who cannot be kept on the rails - that is, who are not contented with methodical teaching - who have within them the seeds of genius
Ciro Santilli couldn't agree more... notably students must have a flexible choice of what to learn.
Students must be allowed to progress as fast as they want by Ciro Santilli 35 Updated +Created

Is this the society that we really want?
From True Genius: The Life and Science of John Bardeen Chapter 2 "Roots":
John ([Bardeen].) and Bill ([his brother]) entered the combined seventh-eighth grade at "Uni High," Wisconsin's University High School, in the same year-John from third grade and William from fifth.
Established in September 1911, the school had been conceived as a laboratory for training high school instructors and for testing progressive ideas in education. In its philosophy and organization, Uni resembled the Dewey School. The students were accelerated as much as possible to keep lessons challenging. One goal was to "introduce pupils to high school methods and subjects before they reached the 9th grade." The fourth quarter, offered during the summer, allowed students who had missed work or had fallen behind to catch up. It also enabled the brightest students to complete senior high school in only three years
...
Even with the disruption of Althea’s death, John completed all his Uni High course work by age thirteen. But as he was "a little leery about graduating so young," he and Bill decided to attend Madison Central High School for two years, taking additional mathematics, science, and literature courses not offered at Uni. By the time John had turned fifteen and Bill seventeen, the two had completed every course of interest at Madison Central. There was no longer any reason to postpone entering college. In the fall of 1923 they both entered the freshman class at the University of Wisconsin.

Students must have a flexible choice of what to learn by Ciro Santilli 35 Updated +Created
This is one of the main reasons why Ciro Santilli invested in OurBigBook.com.
Ciro believes that the only thing students must be forced to learn is to speak read and write English and that a teacher's main job after that is to help students find their next big goals and also ties into the backward design philosophy.
Everything else, the student must choose.
This idea is generally known as self-directed learning.
This is most notable in University entry examinations of poor countries, where students often have to waste one extra year of their lives to go through preparation for the useless university entry exams. And then, surprise surprise, if they actually get in, they find that this is not what they really wanted to do, and they just go through to the end miserably because they understandably they don't want to risk another year of their lives.
Ciro saw this first hand École Polytechnique which was way freer than his university in Brazil.
Steve Jobs's university dropout stories from Steve Jobs' 2005 Stanford Commencement Address also come to mind.

How to become a good programmer? by Ciro Santilli 35 Updated +Created
Or: how to learn X.
This pops up on Reddit every week.
The right question is: what is the most awesome project I can do to improve the world?
Then, once you decide to try one, if that involves programming, only then learn to program to achieve that goal. And don't stop learning what's needed until you either get the thing done, or decide that it is actually not a good idea, or not possible, or that there is something else more important to be done first.
But if doesn't involve programming, then don't learn to program, and learn whatever you actually need to reach that goal instead.
Having that goal is the only way to be motivated to do something.
This is the essence of backward design.

Intro to OurBigBook
. Source.
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:
    • to OurBigBook.com to get awesome multi-user features like topics and likes
    • as HTML files to a static website, which you can host yourself for free on many external providers like GitHub Pages, and remain in full control
    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.
