Ciro Santilli feels that this user has a surprisingly similar contribution pattern (one of the top necromancers) and subjects (Python, Bash) to Ciro Santilli.
Ciro tried to contact him to say hi, but it was hard to find a contact. kenorb, feel free to send Ciro a hi one of those days. Ciro knows kenorb knows Ciro exists because kenorb has in the past starred some of Ciro's stuff, e.g. github.com/cirosantilli/bitcoin-inscription-indexer from Cool data embedded in the Bitcoin blockchain.
His GitHub github.com/kenorb gives name Rafal W. and links to some trading stuff: github.com/EA31337, especially compatible with his stated location of London.
Rafal is Rafael in Polish: en.wikipedia.org/wiki/Rafał It would normally have the l with a stroke, but ASCII.
His LinkedIn sys the R3 company he works at is actually a blockchain company: en.wikipedia.org/wiki/R3_(R3CEV), FOREX appears to be his on-the-side.
They intentionally projected the idea of a semi scary and cool secret society/cult/Fascist/Gestapo/non-racist Ku Klux Klan-like organization
Khômiss members would wear a face cover whenever they would go out "on duty", notably to break a student's door with a fire axe when some student had fucked up particularly bad.
The Khômiss had an ambivalent character: while on one hand they would punish students that they felt had fucked up, they were actually semi approved by the school's head.
And conversely, they could also play pranks on the school head, e.g. vandalizing their office with funny objects if they had made some decision that was particularly unpopular to the students. This also likely with tacit approval, and as a way to be a "cool independent organization that also represents the students".
As such, the Khômiss aimed to be a sort of a "conscience" of the cohort, punishing the evil deeds of either side.
They were apparently unfortunately disbanded by the school in 2013 it seems, just after Ciro Santilli left. They took some poor student out by car and left him more than 1km outsie of the school for some reason. But he had a cell phone and walked came back, so doesn't feel that serious. Likely the political correctness of the times just caught up with them.

The most powerful GUI file manager ever?? Infinite configurability??
Ciro Santilli wasted some time on it before he gave up on file managers altogether and started using only the CLI with a few aliases.
Ahh, Ciro Santilli was certain this was some slang neologism, but it is actually Greek! So funny. Introduced into English in the 19th century according to: www.merriam-webster.com/dictionary/kudo.
Ciro Santilli enjoyed watching the temple flashback moments on YouTube.
Combat in the USA is of course terribly ridiculous due to guns Are Worthless.
Both of them attended Montessori education at some point. Interesting! Mentioned in a talk by Sergey and highlighted at The Google Story.
They stepped down from leading Google roles in 2019: www.npr.org/2019/12/03/784570156/google-founders-brin-page-step-down-pichai-takes-over-as-alphabet-ceo
As The Google Story puts it about Largey:Ciro Santilli likes that.
Scholarship was not just emphasized in their homes; it was treasured.
The exact same problem appears over and over, e.g.:
- transportaion: the last mile of the trip when everyone leaves the train and goes to their different respective offices is the most expensive
- telecommunications: the last mile of wire linking local hubs to actual homes is the most expensive
- electrical grid: same as telecommunications
Ciro Santilli also identified knowledge version of this problem: the missing link between basic and advanced.
On May 19, 2020, Lazlo announced on the Bitcoin Forum at: bitcointalk.org/index.php?topic=137.msg1195Ciro Santilli remembers his father always telling him how when Ciro was small, he would try to grasp the value of money by converting it into how many pizzas he could buy. Well, at least he was not alone.
I'll pay 10,000 Bitcoins for a couple of pizzas.. like maybe 2 large ones so I have some left over for the next day. I like having left over pizza to nibble on later. You can make the pizza yourself and bring it to my house or order it for me from a delivery place, but what I'm aiming for is getting food delivered in exchange for bitcoins where I don't have to order or prepare it myself, kind of like ordering a 'breakfast platter' at a hotel or something, they just bring you something to eat and you're happy!
User bitcoin2paysafe then asks the fundamental practical question:and Lazslo replies:
In which country do you live?
Jacksonville, Florida
zip code 32224
United States
User ender_x then points out afterward:so it is a slightly bad deal even then!
10,000... Thats quite a bit.. you could sell those on www.bitcoinmarket.com/ for $41 USD right now..
Three days later Lazlo's asks again on the thread:and one day later he confirms that the sale was made without naming the buyer:where "jercos" is presumably the Bitcoin Forum username of the buyer. en.bitcoin.it/wiki/Jercos gives his identity as Jeremy Sturdivant.
Pictures: heliacal.net/~solar/bitcoin/pizza/Thanks jercos!
www.thesun.co.uk/news/15049566/other-bitcoin-pizza-jeremy-sturdivant-fortune-hanyecz/ mentions Jeremy sold too early however:
The cryptocash disappeared when Sturdivant used it to "cover expenses" while travelling the US with his girlfriend.
Laszlo's secondary pizza event
. Source. web.archive.org/web/20210217220810/http://heliacal.net/~solar/bitcoin/lightning-pizza/ documents another pizza event, as we have different pizza boxes from the most widely known one: web.archive.org/web/20211219130004/http://heliacal.net/~solar/bitcoin/pizza/ Only image thumbs are archived however. web.archive.org/web/20211016070745/https://www.thesun.co.uk/news/15049566/other-bitcoin-pizza-jeremy-sturdivant-fortune-hanyecz/ however shows a large version that The Sun got their hands on before the takedown.
heliacal.net is presumably his personal website? But is was down as of 2023. But we have Wayback Machine archives of course :-) Latest working one of that page 2021: web.archive.org/web/20211219130004/http://heliacal.net/~solar/bitcoin/pizza/ And some other stalking:Laszlo is truly, literally, the nerd who got very very very lucky!!!

On June 12, 2010 Laszlo re-offers:and on August 4 user MoonShadow takes him up:but finally Laszlo withdrawls the offer:so we understand that the sales happened multiple times!!! Also, we understand that he was probably a miner.
This is an open offer by the way.. I will trade 10,000 BTC for 2 of these pizzas any time as long as I have the funds (I usually have plenty). If anyone is interested please let me know. The exchange is favorable for anyone who does it because the 2 pizzas are only about 25 dollars total, maybe 30 if you give the guy a nice tip. If you get me the upgraded extra large ones or something, I can throw in some more bitcoins, just let me know and we'll work something out.
Well I didn't expect this to be so popular but I can't really afford to keep doing it since I can't generate thousands of coins a day anymore. Thanks to everyone who bought me pizza already but I'm kind of holding off on doing any more of these for now.
TODO list all of the potential sales.

When Ciro Santilli was studying electronics at the University of São Paulo, the courses, which were heavily inspired from the USA 50's were obsessed by this one! Thinking about it, it is kind of a cool thing though.
That Wikipedia page is the epitome of Wikipedia failure to explain things in a way that is of any interest to any learner. Video 1. "Tutorial on LC resonant circuits by w2aew (2012)" is the opposite.
Tutorial on LC resonant circuits by w2aew (2012)
Source. - youtu.be/hqhV50852jA?t=239 series LC circuit on a breadboard driven by an AC source. Shows behaviour on oscilloscope as source frequency is modified. We clearly see voltage going to zero at resonance. This is why thie circuit can be seen as a filter.
- youtu.be/hqhV50852jA?t=489 shows the parallel LC circuit. We clearly see current reaching a maximum on resonance.
Introduction to LC Oscillators by USAF (1974)
Source. - youtu.be/W31CCN_ZF34?t=740 mentions that LC circuit formation is the root cause for Audio feedback with a quick demo. Not very scientific, but cool.
LC circuit by Eugene Khutoryansky (2016)
Source. Exactly what you would expect from an Eugene Khutoryansky video. The key insight is that the inductor resists to changes in current. So when current is zero, it slows down the current. And when current is high, it tries to keep it going, which recharges the other side of the capacitor.Founder: Peter Armstrong
ruboss.com/ documents their stack, a somewhat similar choice to OurBigBook.com as of 2021, notably Next.js. But backend in Ruby on Rails. They actually managed Apollo/GraphQL, which Ciro Santilli would have liked, but din't have the patience for.
The founder/CEO Peter Armstrong www.linkedin.com/in/peterburtonarmstrong/ He looks like a nice guy.
"More complex and general" integral. Matches the Riemann integral for "simple functions", but also works for some "funkier" functions that Riemann does not work for.
Ciro Santilli sometimes wonders how much someone can gain from learning this besides the beauty of mathematics, since we can hand-wave a Lebesgue integral on almost anything that is of practical use. The beauty is good reason enough though.
Ciro Santilli dislikes the fact that they take themselves too seriously. Ciro prefers the jokes and tech approach.
PNG reference implementation. Ahh, if feels good to have a dominating open source reference implementation.

Follows the "certified teacher only" approach which is in Ciro Santilli's opinion a fatal flaw of most elearning systems out there, OurBigBook.com won't suffer from that!

- some don't even have a free license, e.g.: phys.libretexts.org/Bookshelves/Quantum_Mechanics/Quantum_Mechanics_(Fowler)/00%3A_Front_Matter/04%3A_Licensing
TODO how does it work exactly? Do they ask for permission from authors in every case, including when the content has open license? Or when it has open license, do they just do it? In some cases, the notes have no license, so they must have asked.
TODO what is the source code that authors write? LaTeX or something else? LaTeX feels extremely likely given that it is what most original materials were already written in.
They are attempting a "model up this entire university" thing: phys.libretexts.org/Courses which is good. E.g. they have a bunch of "quantum mechanics ones under: phys.libretexts.org/Bookshelves/Quantum_Mechanics
Appears to be UC Davies-based mostly.
They claim to use this closed source backend: www.nice.com/resources/cxone-expert-knowledge-management? Seriously? For a publicly funded project with low-tech requirements?? It is mind blowing.
Some issues:
- the internal cross references are somewhat broken as of 2022.
- their URLs are HUGE! All components of every ancestor are in it. E.g. check this out: phys.libretexts.org/Bookshelves/Quantum_Mechanics/Introductory_Quantum_Mechanics_(Fitzpatrick)/12%3A_Time-Dependent_Perturbation_Theory/12.13%3A_Forbidden_Transitions Insane.
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.

What is Lie theory? by Mathemaniac 2023
. Source. That makes Ciro Santilli most mad about this film is the fact that the dude was passionate about writing, and when he became a genius, rather than write the best novels ever written, he decided instead to play the stock market instead. This paints an accurate picture of 2020's society, where finance jobs make infinitely more money than other real engineering jobs, and end up attracting much of the talent.
Another enraging thing is how his girlfriend starts liking him again once he is a genius, and instead of telling her to fuck off, he stays with her.
The other really bad thing is the ending. He fixed the drug by himself? He scared off De Niro just like that?
Ciro Santilli's LinkedIn profile: www.linkedin.com/in/cirosantilli/ see also: accounts controlled by Ciro Accounts.
LinkedIn fully complies with censorship imposed locally by the Chinese government, and does so in a non-transparent way: cirosantilli.com/china-dictatorship/linkedin.
It is hard to understand what the point of that website is, as it is basically just a more closed version of Facebook, but alas, it has flourished as the only place where people post more useful content compared to Twitter and Facebook. In any case, Ciro just applies the same unfollow policy to all of them: aggressively filter your social media follows.
