E-learning websites must keep content free, only charge for certification by
Ciro Santilli 35 Updated 2025-04-24 +Created 1970-01-01
Another thing that is fine charging for is dedicated 1-to-1 tutor time. This is something Udacity is doing as of 2022.
www.investopedia.com/articles/investing/042815/how-coursera-works-makes-money.asp has a good mention:and it links to: www.freecodecamp.org/news/massive-open-online-courses-started-out-completely-free-but-where-are-they-now-1dd1020f59/, very good article!
MOOCs were first created by people with utopian visions for the internet. This means the idea for platforms like Coursera was likely conceived without a business plan in mind. Nonetheless, Coursera has managed to monetize its platform. It is worth noting, however, that monetization has lead to the effective elimination of the original MOOC idea, which is predicated on ideals like free and open access, as well as the building of online communities.
That is a fundamental guiding principle of OurBigBook.com. The educational content must be licensed CC BY-SA!
Perhaps the most reliable way of reaching this state is E-learning websites must allow students to create learning content.

- www.classcentral.com/about amazing, they can make money just from ads! I wouldn't expect that they could scale like TripAdvisor, because travelling means very local knowledge, I would expect there to be much fewer MOOCs and for them to be more easily findable on Google. Good thing though, this website.
Steve Jobs' 2005 Stanford Commencement Address by
Ciro Santilli 35 Updated 2025-04-24 +Created 1970-01-01
Ciro feels that this resonates a lot with his OurBigBook.com.
Supercut:
The minute I dropped out I could stop taking the required classes that didn't interest me, and begin dropping in on the ones that looked far more interesting.And much of what I stumbled into by following my curiosity and intuition turned out to be priceless later on.Because I had dropped out and didn't have to take the normal classes, I decided to take a calligraphy class to learn how to do this.If I had never dropped in on that single course in college, the Mac would have never had multiple typefaces or proportionally spaced fonts.Of course it was impossible to connect the dots looking forward when I was in college. But it was very, very clear looking backward 10 years later.Again, you can't connect the dots looking forward; you can only connect them looking backward. So you have to trust that the dots will somehow connect in your future. You have to trust in something — your gut, destiny, life, karma, whatever. This approach has never let me down, and it has made all the difference in my life.
Then:
You've got to find what you love.Your work is going to fill a large part of your life, and the only way to be truly satisfied is to do what you believe is great work.And the only way to do great work is to love what you do. If you haven't found it yet, keep looking.So keep looking until you find it.Don't settle.
And:Mirror and morning are not required though, a computer screen will do just fine: www.reddit.com/r/depression/comments/6jtamj/im_at_work_just_staring_at_my_computer_screen/
When I was 17, I read a quote that went something like: "If you live each day as if it was your last, someday you'll most certainly be right."
And then he quotes form the Whole Earth Catalog, a paper Atlas from the '70s he admired:
Stay Hungry. Stay Foolish
The key and central motivation for studying Lie groups and their Lie algebras appears to be to characterize symmetry in Lagrangian mechanics through Noether's theorem, just start from there.
Notably local symmetries appear to map to forces, and local means "around the identity", notably: local symmetries of the Lagrangian imply conserved currents.
More precisely: local symmetries of the Lagrangian imply conserved currents.
TODO Ciro Santilli really wants to understand what all the fuss is about:
Oh, there is a low dimensional classification! Ciro is a sucker for classification theorems! en.wikipedia.org/wiki/Classification_of_low-dimensional_real_Lie_algebras
The fact that there are elements arbitrarily close to the identity, which is only possible due to the group being continuous, is the key factor that simplifies the treatment of Lie groups, and follows the philosophy of continuous problems are simpler than discrete ones.

This is good, and very close competitor to OurBigBook.com.
But they killed local build, so they are going to die.
Ciro Santilli's self perceived compassionate personality by
Ciro Santilli 35 Updated 2025-04-24 +Created 1970-01-01
Ciro Santilli fantasizes that he is more compassionate than average.
He feels that this manifests itself notably through his desire/ability to create amazing documentation content and notably for free.
Also related is Ciro's worry about social inequality and how to reduce it.
In school, especially before university, Ciro felt that he always treated "the ugly/unpopular" (it is horrifying that such perception of a person exists! but true) girls really well, which led some of them to like him romantically. In part this was de to Ciro Santilli's self perceived compassionate personality and enter through the narrow gate approach to life. But was also partly Ciro's fault, he should have been clearer that he was not truly interested, but he was also lonely, curious about how it was like having girlfriend, and it feels good to have someone like you. This was a sin.
He also feels like he treated working class employees (and don't forget, this is Brazil, e.g. his building janitors in São Paulo lived in the nearby favela!) with extreme equality, sometimes even better, than other richer people.
One thing Ciro does not do however is give money to beggars on the street. Those beggars do make Ciro feel extremely bad for not giving, but he feels that they must be drug addicts to be out on the street like that, and that this money would be better invested in OurBigBook.com. But maybe this is just wrong. How fucked up the world is, how far away are we from unconditional basic income???
Once Ciro was hanging out with one of his father's on a group tourist, and she was a lesbian borderline/actually activist social reform person, and she promptly gave to a beggar without batting an eye, and that made a big impression on Ciro, making him feel even worse about himself.
It must be said that at times this compassion can be a weakness see Ciro's trip to the Municipal Market of São Paulo.
