Ciro Santilli 40 Updated 2025-07-16Crazy shady crypto people seem to like Ciro Santilli, so this is in order.
Giving to Ciro Santilli is the worst possible way to launder your money, as donations amounts are clearly publicly disclosed (though not donor identities if they with to remain anonymous), and clear records kept of every donation made (including private note of donor identities if known). Also suspicious donations are promptly reported to the authorities.
Donation refunds upon donor's requests are only made at our discretion, and may be declined, unless required by law of course. This is to reduce the risks of us unknowingly serving as money mules or aiding money laundering.
Ciro Santilli believes that he is not require to report large donations to either:But note that Ciro will preventively report if there are any further suspicious aspects to any donations received.
- charities have to report anonymous donations of £25,000 or more as "serious incident", but Ciro Santilli does not have a registered charity: www.gov.uk/guidance/how-to-report-a-serious-incident-in-your-charity, related: docs.ourbigbook.com/project-governance
- dealers selling goods over 10,000 euros for cash must make a Suspicious Activity Report (SAR) www.gov.uk/guidance/money-laundering-regulations-high-value-dealer-registration. However Ciro Santilli does not sell any goods, only provides services, and services are excluded from the report requirements
TypeScript is good. It does find errors in your JavaScript. But it is a form of "turd polishing". But Ciro Santilli would rather have a polished turd than a non-polished one.
Part of the reason TypeScript became popular is due to the universality of asset bundlers. Once you are already using an asset bundler, changing the
.js extension into .ts to get a less shitty experience is an easy choice.The other big reason is that JavaScript is so lose with type conversions, notably undefined happily converting to strings without problems, and any missing properties of Object happily being undefined. We should actually use ES6 Map everywhere instead of using Objects as maps.
Since TypeScript is not the default form of the language however, it inevitably happens that you need to add external types for a gazillion projects that are using raw JavaScript, and sometimes fight a lot to get things to work. And so we have: github.com/DefinitelyTyped/DefinitelyTyped. Not sure if this is beautiful, or frightening.
But in the end, as with other type of static linters, TypeScript generally transforms a few hard to debug runtime issues, into a bunch of stupid to solve compile time issues, which is generally a good thing.
The fact that this it parses comments JSDoc comments in JavaScript files is quite amazing.
Examples under typescript. Run each one of them with:Helper:
npx tsc example.ts
node example.jstsr() (
# ts Run
f="$1"
npx tsc "$f"
node "${f%.*}.js"
)
tsr example.ts- typescript/inferFromInit.ts. Should fail with:since TypeScript infers the type of
ifrom first assignment asstring, and we then attempt anumberassignment later on - typescript/inferAfterInit.ts. Does not fail, as the first assignment cannot be computationally determined at runtime without breaking computer science.
- typescript/js-from-ts/main.ts: call JavaScript file typescript/js-from-ts/notmain.js from TypeScript.TODO we are unable to make it typecheck that require, i.e. make that fail, but we've seen cases in complex codebases where that did happen and www.typescriptlang.org/docs/handbook/intro-to-js-ts.html has infinite information on supporting it. So... how to make it fail??
npx tsc jsFromTs.ts && node jsFromTs.js - typescript/functionArgument.ts: basic argument tests
- typescript/functionOptionalArgument.ts:
f(n?: number)
- typescript/functionOptionalArgument.ts:
- typescript/functionOptions.ts:
f({n, s}: {n: number, s: string})
Some major annoyances of TypeScript:
- destructuring assignment in function arguments requires repeating all arguments:
- stackoverflow.com/questions/12710905/how-do-i-dynamically-assign-properties-to-an-object-in-typescript how to dynamically assign properties to objects without defining explicit interfaces? We really need a syntax of type:
const myobj = { i: 2, [s string], } if (something) { myobj.s = 'asdf' }
Basic class example.
Ciro like to interpret this as him having "a creative personality" with the tradeoff of generally not being amazing at his well defined jobs.
Ciro is obsessed by that which is "quirky". This also often has a parallel with "naughty". He often fantasizes about an imaginary parallel between that feeling and Jobs and Wozniak's blue box.
Ciro's natural fight-or-flight response is to hide in a little corner, and try to solve the problem out. Then get distracted and start procrastinating. And then he tries to solve the unsolvable. Someone Ciro barely new once told him quite correctly:This is also perhaps why Ciro likes prison decks in Magic: The Gathering. You just sit on your corner, making yourself safer and safer, until the opponent can't do you any harm and concedes.
In the event of war, you would be the type that hides away and makes the bombs.
There are of course infinitely many videos on the "entrepreneurial mindset" online, and it is impossible to know if they are bullshit, or if everyone just feels like that, but OK, just let Ciro feels that he is specially creative will you?
Creative people continuously step outside of the domain of evaluation structures
If you are creative and you go off on tangents all the time, there's some probability that one of those tangents is going to be exactly what is needed at the time, and you are going to become hyper-successful as a consequence[but the probability of that being the right time and place for the idea is extraordinarily low]The sensible thing to tell anybody is "you shouldn't do it, your probability of success is so low, that its better to just to something sensible".
Ciro also one heard a story, likely apocryphal, but still nonetheless resonated with him, that went something like this (TODO find source, Google wasn't helping, stuff that happened before website as usual):
The newly hired manager of some subsection of DuPont (or some other gigantic chemical company) came into the office, and found a chemical engineer, completely drunk in the middle of the day.Outraged, the manager searched for this colleagues who explained.Ah, don't mind John (or some other name), the guy invented Teflon (or some other substance) which accounted for 20% of our revenue last year. Even if he does not do anything else in his entire career, his salary won't make any difference compared to those gains, and we take the chance that he might invent something else later.
Ciro likes this story because although he does not drink, he feels his work mind works in a related way. Often, when there is something really hard he knows needs doing he hides, and distracts himself with less important tasks, or by watching crap on YouTube, because he knows that the hard task will hurt his mind. Then one day he wakes up and says: OK, fuck it, let's do it, and does it.
Once Ciro got a performance review from a colleague that said:This is closely related to effortless effort.
If Ciro spent as much effort on his job as he does on side projects, he'd be the most amazing worker.
Yes, low conscientiousness, give it to me.

Pinned article: 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.
