Ciro Santilli 37 Updated 2025-05-23 +Created 1970-01-01Stuff that is beautiful but useless because it does not make food or houses cheaper.
Or from Ciro Santilli's best random thoughts:
Without technology, one cannot survive. Without art, one cannot live.
But that sure enough has a Jesus semi-precursor, and likely many others: man shall not live by bread alone.
Mostly video games of course.
First when he was really young, about 5, Ciro played a lot of NES, but he doesn't remember things from that era very well. Contra, Ninja Turtles, Battle Tanks, Duck Hunt, and some modern "real world jet" top to bottom rail shooter (TODO identify) are definitely some of the games he clearly remembers playing, see also: Figure "Five year old Ciro Santilli playing NES on a joystick". Nintendo hard was truly a thing back then.
As an honorable mention, Ciro remembers his teenage/young adult neighbours in Jundiaí playing some DOS games on their computer, notably there was a 3D racing one. This must have been around 1995/1997, so using some of the very earliest GPUs. Those games felt so incredibly advanced, including the required setup to play them, which required some command-line commands. It felt like some kind of black magic! But Ciro didn't really play them however.
Ciro then skipped the SNES and handhelds, which he played only through friends because he was cheap (but also because Brazil is a poor country remember, and imports are pretty expensive). He clearly remembers playing Super Mario World for the SNES and Pokemon on friends' Gameboys of course.
Ciro then went straight to 5th generation with the Nintendo 64 in 1994 which his parents bought for him during a trip to the United States. Once again, because he was cheap, the only game he bought was Super Mario 64, which likely came with the console? He played that game to death.
Then came Ocarina of Time, which blew everyone's minds, and Ciro would go to Blockbuster to rent it for the weekend, and again play to death with his friends. You had to arrive early at Blockbuster to rent it, otherwise other people would rent all copies!!!
The only time Ciro got robbed as of 2020 was when an older teenager stopped his bicycle in front of Ciro and took his rented Golden Eye 64 copy away from his hand, and run off. Poor drug addict.
Ciro always felt that the PS1 had a much uglier aesthetics than the N64, and didn't like the console. Playing a bit of Final Fantasy VI on his memory did stick deeply to his mind however. Ciro later played all good PS1 RPGs on emulation during University of São Paulo during amazing solitary nights.
And on the PC, Ciro was particularly touched by Age of Empires II and Diablo II.
As a young teenager Ciro would also play Counter-Strike with his friends at LAN houses. Playing that game would make Ciro extremely anxious, his hands got all cold, and it was a lot of fun.
After this Ciro grew up and notice that the only fun game is that of becoming become rich and famous in the real world.
Outside of video games, Ciro got midly addicted to Magic: The Gathering in his early teens.
Random fun mentions:

You just couldn't resist Googling it and clicking this page, could you? You naughty, naughty bearded programmer nerd. Yes, I'm talking to you.
TODO it is quite hard to actually find non-automatically generated ASCII art of people fucking, most of them are just sexy/horny women drawn by bearded nerds, likely and based on sticky physical paper porn magazines from the 80's, good old days.

OMG, Ciro Santilli only learned about this in 2021 after: twitter.com/ryancdotorg/status/1375484757916672000
If you are going to make a television series, do make it a limited one. Plan one story, and execute it amazingly. Don't let things drag on and on.
There is a lot of "who kills who" useless fluff, and everything to do with the wife is boring, but too much gold otherwise.
It is amazing to see how seasons got better and better until the finale. The last season was amazing, Ciro Santilli actually watched all episodes of that one! This is clearly seen on the evolution of metacritic scores.
Ciro Santilli enjoyed watching the temple flashback moments on YouTube.
Combat in the USA is of course terribly ridiculous due to guns Are Worthless.
Pinned article: ourbigbook/introduction-to-the-ourbigbook-project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- 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-calculusArticles 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.
