Creator of Mozilla rr, of which Ciro Santilli is a huge fan of!
He quit Mozilla in 2016 to try and commercialize an rr extension called Pernosco.
But as of 2022, he advertised himself as part of "Google Research", so maybe that went under, sample source: archive.ph/o9622. TODO when did he start? There's apparently an unrelated homonym: www.linkedin.com/in/rob-ocallahan/
He's apparently very religious, and very New Zelandish, twitter.com/rocallahan auto-describes:
Christian. Repatriate Kiwi.
Terry A. Davis and D. Richard Hipp come to mind. One is tempted to speculate a correlation even, the proportion amongst systems programmers feels so much higher than in other areas of programming! Maybe it is because you have to be a God to do it in the first place.

Ron Maimon Updated 2025-07-26
Ron is mostly known for simultaneously:
Ron seems to share a few philosophies which Ciro greatly agrees with as part of Cirism, which together with his knowledge of physics, make Ciro greatly respect Ron. Such philosophies include:
However he also subscribes to some theories which Ciro Santilli considers conspiracy theories, e.g. his ideas about the Boston Marathon bombing that got him banned from Quora (a ban which Ciro strongly opposes due to freedom of speech concerns!), but the physics might be sound, Ciro Santilli does not know enough physics to judge, but it often feels that what he says makes sense.
chat.stackexchange.com/transcript/message/7104585#7104585 mentions that he was at Cornell University and did all but dissertation, but he mentions that he was still self-taught:
Eugene Seidel: On your personal info page you write that you are not a physics Ph.D. but does that mean you were a physics undergrad in college then went to grad school and finished ABD... or are you entirely self taught?
Ron Maimon: ABD. I am self- taught though, I only went to school for accreditation. I had a thesis worth of work at the time I left grad-school,
Eugene Seidel: ok thanks
Ron Maimon: I was just kind of sickened by academic stuff that was going on--- large extra dimensions were popular then.
Eric Walker: Anyway, thanks Ron -- I'll get back to you with more questions soon, I'm sure.
Ron Maimon: Also I was at Cornell, my advisor left for Cincinnatti, and I was not in very good standing there (I was kind of a jerk, as I still am). Some friends wanted to start a biotech company called "Gene Network Sciences", and I joined them.
This is corroborated e.g. at: web.archive.org/web/20201226171231/http://pages.physics.cornell.edu/~gtoombes/Student_Index.html (original pages.physics.cornell.edu/~gtoombes/Student_Index.html down as of 2023).

Saylor Academy Updated 2025-07-16
This is an interesting initiative which has some similarities to Ciro Santilli's OurBigBook project.
The fatal flaw of the initiative in Ciro Santilli's opinion is the lack of user-generated content. We will never get there without UGC and algorithms, never.
Also as of 2021, it mostly useless business courses: learn.saylor.org unfortunately.
But it has several redeeming factors which Ciro Santilli aproves of:
The founder Michael J. Saylor looks a bit crooked, Rich people who create charitable prizes are often crooked comes to mind. But maybe he's just weird.

Scott Hassan Updated 2025-07-16
The guy who coded the initial version of BackRub, the first version of Google Search, but left before the company formed. TODO how did he meet Largey Brage? Why did he leave Google?
In 1997 he cofounded eGroups, a mailing list management website, together with the mysterious Carl Victor Page, Jr., Larry Page's older brother. eGroups was sold to Yahoo! in 2000 for $432m, just before the Dot-com bubble burst.
As of 2021 his net worth was of "only" $1b, even though his original Google shares would have been worth $13b. He must have sold too much too early to do other cool stuff. archive.ph/IgkMI:
When Mr. Page and Mr. Brin founded Google in 1998, Mr. Hassan bought 160,000 shares for $800. When Google went public in 2004, the shares were worth more than $200 million. The shares, now in Google’s parent company, Alphabet, would be valued at more than $13 billion today [2021].
Did Largey give him this nice deal as a way to thank him for helping start the company, or was it just that they had no big hopes and $800 seemed right? youtu.be/pmXDtTD6vQY?t=146 suggests the stocks were part of his compensation for 3 months of coding work. Also mentioned at: nypost.com/2021/08/20/google-founder-created-revenge-site-against-estranged-wife
In 2001, Scott married a Vietnamese chick called Allison Huynh from university and they had three children.
In 2014 Hassan asked for a divorce, and the proceedings were a shitshow, lasting more than 7 years.
In 2004 he tried strike a $20 million[ref] post-nuptial after Google went public, which she declined, so things were already crappy back then.
Then, during the divorce, Scott even created a revenge website for her as well. He's so petty! Down as of 2024 of course. There are only some weird redirect archives now: web.archive.org/web/20210915000000*/https://allisonhuynh.com redirecting to sites.google.com/view/allisonhuynhcom
To be fair, he did work on a lot of cool stuff after BackRub for which he deserves credit, not the least the company that created the Robot Operating System, which is a cool sounding open source project, which is awesome. But this divorce story is so damning! He should just own up to it, split the cash, and move on... The fact that the Google money came from an investment before marriage likely complicates things.
The fact that he does not have a Wikipedia page as of 2022 is mind blowing, especially after divorce details. Maybe Ciro Santilli will create it one day. Just no patience now. OK, done it June 2022: en.wikipedia.org/wiki/Scott_Hassan let's see if it lasts. The page lasted but ended up being Ciro Santilli's first edit war, how exciting:
Looking a the history, he just kept revealing different IPs and continuously reverting, which other people put back in. Another of his IPs:
  • 24.234.111.66 is marked as being from Las Vegas online.
There is also an interesting edit from 2600:1700:5470:5c50:7566:9580:1b60:ab41 which mentions without source the little known fact
after working at Washington University's Medical Libraries Group (having been recruited out of SUNY Buffalo for the summer).
so it could be Hassan adding some actually good and interesting information to the article. That one however also has an edit to en.wikipedia.org/wiki/Ernest_Nagel so maybe it's not him.

1 - 2Have worked with it previously but either not much, or rusty.
I copied this grading scale mechanism from a failed Google interview ;-)
One problem with it is that I am always very hesitant to put a 5 on anything, who can not look at the documentation?
It is also hard to scope things right. Who can claim to be a C++ or Linux kernel expert, even if you wrote a book about it, since those are such humongous topics?
As a result, I haven't updated this in a while, and things may be out of date.
If your project does something that interests me, I can what it takes to contribute. Tell me what I must know, how long I have to learn it, and I'll call you back when I've mastered it.
Stack Overflow Updated 2025-07-16
The best place to get answers to programming questions as of 2019. Google into Stack Overflow is always the best bet.
An overview of Ciro Santilli's Stack Overflow contribution can be found at: Ciro Santilli's Stack Overflow contributions.
Figure 1.
Stack Overflow in a nutshell
. Source.
As the "WTF look at my points" guy, Ciro Santilli approves of this meme. A few more elements could be added, notably deletion of the last link-only answer, but good enough.
By the profile image, the "Grammar Nazi" editor is actually appropriately the notorious serial editor Peter Mortensen. Ciro Santilli welcomes grammar fixes, but more subjective style fixes can be a bit annoying.
Stack Overflow is doomed Created 2024-07-29 Updated 2025-07-16
Stack Overflow does have an super naive reputation and moderation system and overly restrictive subject matter, which Ciro Santilli wants to improve upon with OurBigBook.com.
However, it is the best that we have now, and if you use it like Ciro, you won't get tired:
  • monitor only rare tags that you know a lot about, let others answer duplicates on big tags for you
  • only answer on bigger tags when you find a better answer than can be found on the page
  • accept that sometimes things are bound to go wrong, that reputation is meaningless, and move on
What else would you expect from a naive algorithm system that has 10 million newbies asking stuff?
The key problem of Stack Overflow is closurism. The answer close feature is just not made for purpose. The sole purpose of "closing" should be to prevent easy reputation farming. What it should do instead, is remove points gained from duplicates and off topic questions. But it should not prevent new answers. The disk space costs nothing, and Google doesn't care about the closed status of a question.
As of 2024, the only competitor of Stack Overflow is Reddit (besides LLMs, which do nothing but extract data from those two and other sites). Reddit removed the mandatory thread locking after 6 months, but still lacks the Q&A focus required for greatness. Its community however is much more chill and doesn't close and downvote the fuck out of everything.
The Final Encyclopedia (Paul Allen) Updated 2025-07-16
The Google Story Chapter 21. A Virtual Library mentions that Paul Allen was interested in trying to create something like the "Final Encyclopedia" from this book. This is somewhat the same motivation for Google Books and Google's activities more broadly, as shown in their organise the world's information mission statement.
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 Materials Project Created 2024-12-13 Updated 2025-07-16
Signup required for any search, bastards. But it's free. Once you have a URL however it is visible without login, so you could just Google it too.
Long story short, the project is so far a complete failure on the most important metric: number of regular users, which current sits at exactly one: myself.
There were notable users who found the project online and who actually tried to use the website for some content and provided extremely valuable feedback:Unfortunately after the period of a few weeks they stopped using it to follow their other priorities instead. Which is of course totally fine, however sad.
I still believe that the OurBigBook Web feature is a significant tech innovation that could make the website go big.
I also believe that the project gets many fundamentals of braindumping right, notably the infinitely deep table of contents without forced scoping, e.g.:
- Mathematics
  - Calculus
does not make Calculus have an ID orr URL of mathematics/calculus, rather it's just calculus.
But there is a fundamental difficulty in reaching critical mass to that self-sustaining point, as people don't seem to be convinced by these logical "my system is better" argument alone, as opposed to having them Google into stuff they need now and then understand that the project is awesome.
A closely related critical mass issue is that existing big multiuser knowledge base websites such as Stack Overflow and Wikipedia have a tremendous advantage on PageRank. No matter how useless a Wikipedia article about something is, it will always be on top of Google within a week of creation for title hits. And since the main goal of publishing your stuff is to get it seen, it makes much more sense for writers to publish on such existing websites whenever possible, because anywhere else it is way way less likely to be seen by anybody.
Even I end up writing way more on Stack Overflow than on OurBigBook as a programmer. But I still believe that there is a value to OurBigBook, for the usual reasons of:
  • it allows you to organize a more global view of a subject, i.e. a book. Even I write answers on Stack Overflow, I also tend to organize links to these answers in a structured ways here, see e.g. big topics such as SQL
  • deletionism and overly narrowness of allowed topics/style
Perhaps what saddens me the most is that even on GitHub stars/Twitter/Hacker news terms there is almost no interest in the project despite the fact that I consider that it has innovations, while many other note taking apps as well in the thousands of stars. Maybe I'm just delusional and all the tech that I'm doing is completely useless?
Part of the issue is probably linked to the fact that most other note taking apps focus on "help me organize my ideas so I can make more money" and often completely ignore "I want to publish my knowledge", and stuff that helps you make money is always easier to sell and promote.
OurBigBook on the other hand a huge focus on "I want to publish me knowledge". It aims almost single mindedly in being the best tool ever for that. However this doesn't make money for people, and therefore there are going to be way less potential users.
I do believe strongly that all it takes is a few users for the project to snowball. For some people, once you start braindumping, it is very addictive, and you never want to stop basically. So with only a few of those we can open large parts of undergrad knowledge to the world. But these people are few, and so far I haven't been able to find even a single one like me, and on top of that convince them that I have created the ultimate system for their knowledge publishing desires.
Another general lesson is that I should perhaps aimed for greater compatibility with existing systems such as Obsidian. Taking something that many people already know and use can have a huge impact on acceptance. E.g. anything that touches Obsidian can reach thousands of stars: github.com/KosmosisDire/obsidian-webpage-export. Note taking apps that aim for "markdown" compatibility also tend to fare better, even if in the end you inevitably have to extend the Markdown for some of your features. And WYSIWYG, which I want but don't have, is perhaps the ultimate familiarity.
Another issue compared to other platforms is that OurBigBook just came out late. Obsidian launched in 2020. Roam Research and Trillium Notes also came earlier. And it is hard to fight the advantage already gained by those on the "I'm going to take some personal notes" area. I do believe however that there a strong separation between "these are my personal notes" and "I want to publish these". Once you decide to publish your knowledge, you immediately start to write in a different way, and it is very hard to convert pre-existing "private" notes into ones suitable for public consumption.
Updates / Post OurBigBook job search round 2025 Created 2025-05-07 Updated 2025-07-16 2025-07-16
I shouldn't be doing this on funded OurBigBook time which is until the end of May, but I was getting too nervous and decided to start a casual job search to test the waters.
In particular I want to see if I can get past the HR lady step without toning down my online profiles. If nothing works out for the next round I'll be hiding anything too spicy like:
Another interesting point is to see if French companies are more likely to reply given that Ciro Santilli studied at École Polytechnique which the French worship.
Figure 1. . Ciro's profiles may be a bit too much for the HR ladies who reject his job applications on the spot. To be fair, perhaps not enough years of experience for certain applications and job hopping may have something to do with it too. But since they don't ever tell you anything not to get sued, we'll never know.
I'm looking in particular either for:
I spent the last two weeks doing that:
I'll make sure to add two weeks of OurBigBook work after May to make up for this.
Updates / Quick fun with the Common Crawl web graph Created 2025-02-26 Updated 2025-11-05
I wanted to do a quick exploration of open PageRank implementation and data.
My general motivation for this is that a PageRank-like algorithm could be useful for more accurate user and article ranking on OurBigBook, see: Section "PageRank-like ranking"
But it could also be just generally cool to apply it to other graph datasets, e.g. for computing an Wikipedia internal PageRank.
A quick Google reveals only Open PageRank, but their methods are apparently closed source.
Then I had a look at the Common Crawl web graph data to see if I could easily calculate it myself, and... they already have it! See: Section "Common Crawl web graph official PageRank"
Their graph dumps are in BVGraph graph file format, which is the native format of the WebGraph framework, which implements the format and algorithms such as PageRank.
The only thing I miss is a command line interface to calculate the PageRank. That would be so awesome.
The more I look at it the more I love Common Crawl.

Usenet personality Updated 2025-07-16
Ciro Santilli does the same via Google searches and Twitter/Reddit searches for himself, you can't invent anything new nowadays:
Kibo was known for his high-volume but thoughtful posts, but achieved Usenet celebrity circa 1991 by writing a small script to grep his entire Usenet feed for instances of his name, and then answering personally whenever and wherever he was mentioned, giving the illusion that he was personally reading the entire feed.
Who bought Laszlo Hanyecz pizza? Updated 2025-07-16
TODO who bought the Bitcoins? Is anyone else besides Jeremy Sturdivant
The original forum thread bitcointalk.org/index.php?topic=137.msg1195 suggests multiple purchases were made, until he had to withdrawl the offer. Perhaps an easier question is how many pizzas he got in the first place.
www.reddit.com/r/Bitcoin/comments/13on6px/comment/jl55025/?utm_source=reddit&utm_medium=web2x&context=3 mentions without source:
I know. Laszlo Hanyecz estimates that he spent 100,000 BTC on pizza in 2010. Laszlo is the man that invented GPU mining and he mined well over 100,000 BTC.
One source is: bitcoinmagazine.com/culture/the-man-behind-bitcoin-pizza-day-is-more-than-a-meme-hes-a-mining-pioneer
Related thread from May 2023: bitcointalk.org/index.php?topic=5453728.msg62286606#msg62286606 "Did Laszlo Hanyecz exchange 40000 BTC for 8 pizzas, not 10000 BTC for 2 pizzas?" but their Googling is so bad no one had found the 100,000 quote before Ciro.
As per bitcoin.stackexchange.com/questions/113831/searching-the-blockchain-based-on-transaction-amount-and-or-date at blockchair.com/bitcoin/outputs?s=time(asc)&q=value(1000000000000),time(2010-05-18..2010-08-05) we can list all the transactions made between the offer and withdrawal dates for value exactly 10k. There are only about 20 of them, and including someone the 22nd of May, so it is extremely likely that this will contain the hits. No repeated recipients however, so it is hard to progress with more advanced analytics tools
Some of the transactions are:
8 d1a429c05868f9be6cf312498b77f4e81c2d4db3268b007b6b80716fb56a35ad (29 May) is a common looking transaction with a single input from 1Bc7T7ygkKKvcburmEg14hJKBrLD7BXCkX and two outputs, one likely being the change to 1GH4dRUAagj67XVjr4TV6J9RFNmGYsLe7c and the other the actual value to 138eoqfNcEdeU9EG9CKfAxnYYz62uHRNrA.

x86 custom instructions Updated 2025-07-16
Intel is known to have created customized chips for very large clients.
This is mentioned e.g. at: www.theregister.com/2021/03/23/google_to_build_server_socs/
Intel is known to do custom-ish cuts of Xeons for big customers.
Those chips are then used only in large scale server deployments of those very large clients. Google is one of them most likely, given their penchant for Google custom hardware.

YouTube Updated 2025-07-16
Ciro Santilli publishes videos of this not-so-common visual programming experiments on his YouTube channel occasionally: www.youtube.com/c/CiroSantilli. Ciro should however not be lazy and also upload each video produced to Wikimedia Commons, since YouTube does not offer a download option even for videos marked with a Creative Commons license: www.quora.com/Can-I-download-Creative-Commons-licensed-YouTube-videos-to-edit-them-and-use-them/answer/Tarmo-Toikkanen!
This is also where Ciro's downtime converged to in his early 30's, since he long lost patience for stupid video games and television series.
Ciro developed one interesting technique: while scrolling through YouTube's useless recommendations, when he understands what a channel is about, he either immediately:
  • subscribes if it is amazing and then "Don't recommend channel"
  • otherwise just "Don't recommend channel" immediately
This helps to keep this feed clean of boring stuff he already knows about. There is unfortunately an infinite amount of useless videos out there however on the topics of:
and no matter how much you say you don't want to hear about them, YouTube juts keeps on sending more.
Things Ciro hates about YouTube:
  • you can't follow or ignore a subject, only indirectly tell the algorithm about that. Once you click a popular cat video, you will be forced to watch cat videos for all eternity.
