The beauty of mathematics Updated 2025-07-16
Ciro Santilli intends to move his beauty list here little by little: github.com/cirosantilli/mathematics/blob/master/beauty.md
The most beautiful things in mathematics are results that are:
Good lists of such problems Lists of mathematical problems.
Whenever Ciro Santilli learns a bit of mathematics, he always wonders to himself:
Am I achieving insight, or am I just memorizing definitions?
Unfortunately, due to how man books are written, it is not really possible to reach insight without first doing a bit of memorization. The better the book, the more insight is spread out, and less you have to learn before reaching each insight.

These are basically technically minded people that Ciro Santilli feels have similar interests/psychology to him, and who write too much for their own good:
Another category Ciro admires are the "computational physics visualization" people, these people will go to Heaven:

The bullying of young Ciro Santilli Updated 2025-07-16
When Ciro Santilli was very young, about 6, he was a fatty, and other evil boys picked on him.
Ciro was even more stupid than as of 2020, and continued to try and hang out with those evil kids to show them he was cool too or that he was strong, and so continued to get hurt.
Advice to his children: stay away from evil people.
The bullied sometimes feels an almost masochistic desire to overcome the bullies' contempt, and to try and either become friends with the bullies, or to overpower them.
You must never give into those thoughts.
If you come across evil people, smile a fake smile to them, and walk away, but never give your back to them, and always be ready to fight.
If they laugh at you, know that you are shit like everyone else, pretend to laugh with them, take their post and repost it on your public profile, and silently stay away from those idiots.
Never show any weakness.
If a fight is likely, always be ready, always have your friends nearby, be as well armed as the enemy, and never be outnumbered.
On the Internet, never care about e-bully posts, either block them immediately, and anyone that likes their posts, or follow Ciro's reply policy.
Call parents or other authorities as soon as there is risk of physical harm. Better a living free pussy than dead or in youth detention for murder. Similar advice applies if you are going to jail I guess.
The Sikh knife, the Kirpan, which Sikhs must carry at all times as a religious obligation, also comes to mind. The Sikh must have been bullied out of the their minds at some point in history, Ciro understands.
Non-violence only works when you have bodies to spare from your followers.
Perhaps it was good to learn those lessons early, before the stakes were too high. Adults fake it much better, and therefore it is harder to learn those lessons from them, but they are still just as evil on the inside.
Ciro Santilli believes that there is a positive correlation between being a software engineer and liking Buddhist-like things.
Maybe it is linked to minimalism and DRY, which software engineers value so greatly.
Even Ciro had to try an unoriginal Buddhist joke intro in one of this Stack Overflow answers.
Ciro also feels that his "minimal reproducible example" scientific language/concept learning method obsession of breaking things into tiny sub-problems has a strong link with Koans.
Some notable Buddhism/programmer examples:
Another thing that points the correlation out is the existence of wattsalan.github.io/ on a github.io about Alan Watts.
The Criterion Collection Updated 2025-07-16
Respect, big respect to those people.

A slow development test cycle will kill your software.
New developers won't want to learn your project, because they would rather shoot themselves.
This means that build time, and the time to run tests, must be short.
5 seconds to rebuild is the maximum upper limit.
Of course, at some point software gets large enough that things won't fit anymore in 5 seconds. But then you must have either some kind of build caching, or options to do partial builds/tests that will bring things down to that 5 second mark.
You also have to spend some time profiling execution and build from scratch times.
A slow build from scratch will mean that your continuous integration costs a lot, money that could be invested in a new developer!
It also means that people won't bother to reproduce bugs on given commits, or bisect stuff.
One anecdote comes to mind. Ciro Santilli was trying to debug something, and more experience colleague came over.
To reproduce a problem, ciro was running one command, wait 5 seconds, run a second command, wait 5 seconds, run a third command:
cmd1
# wait 5 seconds
cmd2
# wait 5 seconds
cmd3
The first thing the colleague said: join those three commands into one:
cmd1;cmd2;cmd3
And so, Ciro was enlightened.

The Employment Test Updated 2025-07-16
That's Ciro Santilli's favorite. Of course, there is a huge difference between physical and non physical jobs. But one could start with replacing desk jobs!
The Google Story Updated 2025-07-16
Has some good mentions, but often leaves you wanting more details of how certain things happened, especially the early days stuff.
Does however paint a good picture of several notable employees, and non-search projects from the early 2000's including:
  • the cook dude
  • porn cookie guy
  • the unusual IPO process
Paints a very positive picture of the founders. It is likely true. They gave shares generously to early employees. Tried to allow the more general public to buy from IPO, by using a bidding scheme, rather than focusing on the big bankers as was usual.
The introduction mentions that Google is very interested in molecular biology and mining genetics data, much like Ciro Santilli! Can't find external references however...
Two of the most compelling areas that Google and its founders are quietly working on are the promising fields of molecular biology and genetics. Millions of genes in combination with massive amounts of biological and scientific data are an excellent match for the Google search engine, the tremendous database the company has in place, and its immense computing power. Already, Google has downloaded a map of the human genome and is working closely with biologist Dr. Craig Venter and other leaders in genetics on scientific projects that may lead to important breakthroughs in science, medicine, and health. In other words, we may be heading toward a time when people can google their own genes.
The book gives good highlight as to why Google became big: search was just an incredibly computationally intensive task. From very early days, Largey were already making up their own somewhat custom compute systems from very early days, which naturally led into Google custom hardware later on. Google just managed to pull ahead on the reinvest revenue into hardware loop, and no one ever caught them back. This feels more the case than e.g. with Amazon, which notoriously had to buy off dozens of competitors to clear the way.

The ideal university Updated 2025-07-16
This is a version of free gifted education but more focused on university.
This is Ciro Santilli's ideal university system. It is a system that actually lives up to the name "Open University":

So far as of the early 2020's, the university that comes closest to some but not all of these principles is the University of the People. It's sad that it's such a crappy unknown thing, but it is what it is.
The Legend of Zelda: Ocarina of Time Updated 2025-07-16
This game was mind blowing to Ciro Santilli and all kids. It felt so real. The perfect contrast between peaceful town work and saving the world. OMG.
The Math Genome Project Updated 2025-07-16
The website was dead as of February 2025. Last archive: web.archive.org/web/20240418004442/http://www.themathgenome.com/ Pings:They were seeking help on May 2024:so its likely the followup death. LinkedIn post gives basic stack: MERN stack, Heroku, Supabase/MongoDB Atlas.
Appears to support multiple proof assistant backends including Lean, Hol and Coq.
A discussion on the Lean Zulip: leanprover.zulipchat.com/#narrow/stream/113488-general/topic/The.20Math.20Genome.20Project/near/352639129. Lean people are not convinced about the model in general it seems however.
TODO not viewable without login?

Built by this dude John Mercer:He must be independently wealthy or something to do such a project? What a hero. But he seems to have jobs. On the side? Hardcore.

Does the website actually automatically check the formal proofs, or is this intended to be implemented at some point? And if yes, is it intended to allow proofs to depend on other proofs of the website (possibly by other people)
Owner:
Hi Ciro, yes we will be releasing in-browser proof assistant environments/checkers (e.g. Lean). Our goal is not to replace the underlying open-source repos (e.g. Mathlib) so the main dependency will be on the current repos; then when statement formalizations and proofs come in and are certified they can be PR'd to the respective repos. So we will be the source of truth for the informal latex code but only a stepping stone and orchestration layer on the way to the respective formal libraries.
So apparently there will be proof checking, but no dependencies between proofs, you still have to pull request everything back and face the pain.
The Matrix (1999) Updated 2025-07-16
Ciro Santilli just keep watching that a gazillion times whenever it showed on TV.
All action scenes are useless crap, but the premise with Ciro's precious simulation hypothesis subject, related physics and the illusion of life.
It is a shame that the key premise of using human bodies to produce energy is completely and impossibly stupid. You would obviously get more energy by directing burning the food you feed into humans.
If the film had been made later, maybe the much more plausible concept of AI alignment would would have been used instead. What a shame.
