It's an open source note taking system that can publish from lightweight markup files in your computer both to a multi-user mind melding dynamic website, or as a static website. It's like Wikipedia + GitHub + Stack Overflow + Obsidian mashed up. Source code: github.com/ourbigbook/ourbigbook.
Sponsor me to work on this project. For 200k USD I will quit my job or not get a new job and work on OurBigBook full time for a second year to try and kickstart The Higher Education Revolution. Status: ~44k / 200k USD. At 2M USD I retire/tenure and work on open STEM forever. How to donate: Section "Sponsor Ciro Santilli's work on OurBigBook.com".
I first quit my job 1st June 2024 to work on the project for 1 year after I reached my initial 100k goal mostly via a 1000 Monero donation. For a second follow up year, I increased my requirement to 200k USD to give me more peace of mind. So the total donation so far is 144k, and if I reach a total of 300k USD, then I'll work on the project for a second year. A second year greatly improve chances of success: year one I improved my tech, year two I come guns blazing to solve courses and expand further.
Mission: to live in a world where you can learn university-level mathematics, physics, chemistry, biology and engineering from perfect free open source books that anyone can write to get famous. More rationale: Section "OurBigBook.com"
Explaining things is my superpower, e.g. I was top user #39 on Stack Overflow in 2023[ref][ref] and I have a few 1k+ star educational GitHub repositories[ref][ref][ref][ref]. Now I want to bring that level of awesomeness to masters level Mathematics and Physics. But I can't do it alone! So I created OurBigBook.com to allow everyone to work together towards the perfect book of everything.
My life's goal is to bring hardcore university-level STEM open educational content to all ages. Sponsor me at github.com/sponsors/cirosantilli starting from 1$/month so I can work full time on it. Further information: Section "Sponsor Ciro Santilli's work on OurBigBook.com". Achieving what I call "free gifted education" is my Nirvana.

Besides that, I'm also a freedom of speech slacktivist and recreational cyclist. I like Chinese traditional music and classic Brazilian pop. Opinions are my own, but they could be yours too. Tax the rich.
Let's create an educational system with:
- no distinction between university and high school, students just go as fast as they can to what they really want without stupid university entry exams
- fully open source learning material
- on-demand examinations that anyone can easily take without prerequisites
- granular entry selection only for space in specific laboratories or participation in specific novel research projects
I offer:
- online private tutoring for:
- any STEM university course
- passionate younger STEM students (any age) who want to learn university level material and beyond. Can your kid be the next Fields Medalist or Nobel Prize winner? I'm here to help, especially if you are filthy rich! I focus moving students forward as fast as they want on and on producing useful novel tutorials and results
Let your child be my Emile, and me be their Adolfo Amidei, and let's see how far they can go! I will help take your child:and achieve their ambitious STEM goals!- into the best universities
- into the best PhD programs
- educational consulting for institutions looking to improve their STEM courses
- do you know that course or teacher that consistently gets bad reviews every year? I'll work with the teacher to turn the problem around!
- are you looking to create a consistent open educational resources offering to increase your institutions internationally visibility? I can help with that too.
My approach is to:For minors, parents are welcome to join video calls, and all interactions with the student will be recorded and made available to parents.
- propose interesting research projects. The starting point is always deciding the end goal: Section "Backward design"
- learn what is needed to do the project together with the student(s)
- publish any novel results or tutorials/tools produced freely licensed online, and encourage the student to do the same (Section "Let students learn by teaching", digital garden)
I have a proven track of explaining complex concepts in an interesting and useful way. I work for the learner. Teaching statement at: Section "How to teach". Pricing to be discussed. Contact details at: Section "How to contact Ciro Santilli".
I am particularly excited about pointing people to the potential next big things, my top picks these days are:I am also generally interested in:
- quantum computing
- AGI research, in particular AI code generation, automated theorem proving and robotics
- assorted molecular biology technologies
- 20th century physics, notably AMO and condensed matter
- the history of science, and in particular trying to look at seminal papers of a field

ASCII art of a Force of Will Magic: The Gathering card inscribed in the Bitcoin blockchain
. Artist unknown, uploaded December 2014. Part of Section "Cool data embedded in the Bitcoin blockchain" where Ciro Santilli maintains a curated list of such interesting inscriptions.
This was a small project done by Ciro for artistic purposes that received some attention due to the incredible hype surrounding cryptocurrencies at the time. Ciro Santilli's views on cryptocurrencies are summarized at: Section "Are cryptocurrencies useful?".
YellowRobot.jpgJPG image fully embedded in the Bitcoin blockchain depicting some kind of cut material art depicting a yellow robot, inscribed on January 29, 2017.
Ciro Santilli found this image and others during his research for Section "Cool data embedded in the Bitcoin blockchain" by searching for image fingerprints on every transaction payload of the blockchain with a script.
The image was uploaded by EMBII, co-creator of the AtomSea & EMBII upload mechanism, which was responsible for a large part of the image inscriptions in the Bitcoin blockchain.
The associated message reads:This is one of Ciro Santilli's favorite AtomSea & EMBII uploads, as it perfectly encapsules the "medium as an art form" approach to blockchain art, where even non-novel works can be recontextualized into something interesting, here depicting an opposition between the ephemeral and the immutable.
Chiharu [EMBII's Japanese wife] and I found this little yellow robot while exploring Chicago. It will be covered by tar or eventually removed but this tribute will remain. N 41.880778 E -87.629210
At twitter.com/EMBII4U/status/1615389973343268871 EMBII announced that he would be giving off shares of that image on Sup!?, a Bitcoin-backed NFT system he was; making. In December 2023, he gave some shares of the robot to Ciro Santilli.
2010 Wayback Machine archive of starwarsweb.net
. This website was used as one of the CIA 2010 covert communication websites, a covert system the CIA used to communicate with its assets. More details at: Section "CIA 2010 covert communication websites".
Ciro Santilli had some naughty OSINT fun finding some of the websites of this defunct network in 2023 after he heard about the 2022 Reuters report on the matter, which for the first time gave away 7 concrete websites out of a claimed 885 total found. As of November 2023, Ciro had found about 350 of them.
2010 Wayback Machine archive of noticiasmusica.net
. This is another website that was used as one of the CIA 2010 covert communication websites. This website is written in Brazilian Portuguese, and therefore suggests that the CIA had assets in Brazil at the time, and thus was spying on a "fellow democracy".
Although Snowden's revelations made it extremely obvious to the world that the USA spies upon everyone outside of the Five Eyes, including fellow democracies, it is rare to have such a direct a concrete proof of it visible live right on the Wayback Machine. Other targeted democracies include France, Germany, Italy and Spain. More details at: USA spying on its own allies.

Some people from them contacted Ciro Santilli after Ciro's initial publishing of CIA 2010 covert communication websites.
After a quick Discord chat with them, it was apparent that these people were really cool and knowledgeable.
Also many of them seem to think university is broken and just go hack straigh away.
Also they don't seem to need sleep. Go figure!
With pepole like this, there's hope for Brazil: Section "What poor countries have to do to get richer".
The CIA really likes this registrar, e.g.:

"Sources and methods" seems to be an official CIA/NSA terminology to talk about the main categories things that whistleblowers were not supposed to whistleblow.
It came to Ciro Santilli's attention in the Reality film about Reality Winner, and are words she apparently used extensively and which are quoted e.g. at www.theguardian.com/us-news/2022/jul/25/reality-winner-leaked-file-on-russia-election-hacking-because-public-was-being-lied-to
The term is more broadly used however outside of the NSA, e.g. it is also present on this website which talks about the CIA 2010 covert communication websites fiasco.
Sponsor Ciro Santilli's work on OurBigBook.com 1000 Monero donation Anonymity of the donation Updated 2025-05-23 +Created 1970-01-01
The first sensation Ciro Santilli got was as if God himself had come down from heaven to toy with an unsuspecting human being. God running an experiment. Or perhaps an AGI that had already secretly taken over. Not very different.
Like with God, this was the answer to Ciro's prayers on Twitter. A one way conversation that leaves you uncertain of the details.
Whichever the case, Ciro is going to put on the best show he possibly can for your money, documenting every step along the way in usual fashion!
Ciro ran this over and over in his head, and the only big risk of anonymity is that if this money is ever proven to be from the proceeds of crime, he would have to give it back to the government and "lose one year's salary he would have otherwise gained".
However, that worst case scenario is not bad enough. If anything, it was a great excuse to quit his job for his family and wife is already worth it. Ciro could do it and survive, though situation would deteriorate slowly. But he was a coward previously.
Ciro does however feel that there is good chance that it is legitimate.
Ciro Santilli's Stack Overflow contributions are exceptional, he's amazing right! He deserves this! Of course, there is danger in this rationale which scammers could exploit. But bro, if scammers are going to send 100k USD to me, then please continue to do so!
Also which criminal would be stupid enough to donate proceeds of crime to a highly public person who is going to clearly announce it?
Just be warned, if you come with a baseball bat trying to get the money back by force, I will call the police immediately and by God you will not get it!!
Given this, Ciro just keeps thinking about the likely profile of the donor:
But the "why anonymous if not criminal" question remains. Generally rich people want recognition both for:Two options that come to mind:
- reputation washing
- to make their donation mechanisms higher profile which allows raising more and attracting better candidates and reach greater impact
- rich crypto dude that doesn't want thieves to know he is rich
- more public rich person that doesn't want association with Ciro Santilli's naughty projects, notably Ciro Santilli's campaign for freedom of speech in China, but perhaps also CIA 2010 covert communication websites, which could hurt business.
- crazy rich person with a philosophy of "if they knew who I was it might interfere with what they do". AKA a God.
This is an update to the article: Section "CIA 2010 covert communication websites"

There must have been a massive Johnny Carson amongst the contractors at that time, given that we previously also knew about
alljohnny.com, a site dedicated fully to him! Both of these sites also serve as some of the earliest examples we've got so far, dating back to 2004 and 2005.

. Source. This one was a previously known website featuring Johnny Carson.Another cool discovery is that I found the Getty Images source of the Jedi boy on their Star Wars themed site starwarsweb.net: web.archive.org/web/20101230033220/http://starwarsweb.net/ The photo can still be licensed today as of 2025: www.gettyimages.co.uk/detail/photo/little-jedi-royalty-free-image/172984439. I found it by searching for "jedi boy" on gettyimages.co.uk. The photo is credited to username
madisonwi, presumably an alias of a photographer from Madison, Wisconsin. Inspired by this I reverse image searched and found the source of many other stock images from other websites, and I pinged their authors whenever I could locate them e.g. x.com/cirosantilli/status/1899750172260806711.

. There were two small advances that led to the discovery of new domains:
- while looking for a way to procrastinate I decided to scrape justdropped.com/drops/ for fun. That website lists expired domain names and see if it would yield any new results.I had already scrapped other expired domain websites before and used that data, and I hoped that this one would provide some new domain hits, even though it had very large overlap with the other websites I had scraped domains from previously.Such domain name lists tend to contain all SCAM domains in existence, since those inevitably expire once the scammers are caught.
- even more importantly, I noticed by chance that I was being too strict on a small part of my fingerprinting which was excluding a few good domains, by removing any hits that had multiple archives of the Communication mechanism
With those two new developments, I then kicked off my pre-existing search pipelines searching for domain names with the word
news on them, an amazingly efficient heuristic because many of the websites were disguised as news aggregators, and after a few hours theses new hits emerged. A few of those also led to the discovery of new IPs which then led to new domains.One entirely new IP range was found around fastnews-online.com from 208.93.112.105 to 208.93.112.125. There were many domain names with very promising names in the range, but unfortunately for some reason most didn't have Wayback Machine Archives so I didn't count them as hits as per my guidelines.
2009 Wayback Machine archive of fastnews-online.com
. Also the newly found todaysengineering.com at 208.254.38.39 appears to form an IP range with the previously known nejadnews.com at 208.254.38.56, but I couldn't find any other domains in the region with our current data sources.

. All other domains either slot into previously known IP ranges, or more commonly don't currently have a known IP, though they would likely just slot in existing ranges if we had better data.
Thanks to Jack Rhysider from the Darknet Diaries podcast for pointing me to the existing of the 2022 Reuters article that kickstarted my research on the subject!
One outcome of this update is that I've increased my jq level to better automate the maintenance of the hits.json file were I store all the known websites in JSON format. I love that tool so much, I managed to merge two JSONs with it removing duplicates and then sort the JSON as desired. Beauty.

Updates 60 new CIA website screenshots discovered on CQ Counter Updated 2025-05-23 +Created 2025-04-15 2025-05-23
This is an update to the article: Section "CIA 2010 covert communication websites"
While procrastinating I suddenly remembered that cqcounter.com/siteinfo/ has screenshots of many many old websites, and I decided to look at possible hits in known IP ranges for which the Wayback Machine archive was broken.
Luckily I had already maintained a clear list of known domains in IP ranges which had no or broken wayback machine archive, so I just went over those.
This led to finding 60 novel screenshots of previously examined domains that are in common CIA-style, thus confirming them as hits beyond reasonable doubt in my mind. This also publicly revealed for the first time how a few new websites looked like, and what was their content, and in particular the target language, which could sometimes not be easily determined from the domain name alone.
This novel CQ Counter screenshot interpretation, plus a few new random discoveries and a slight relaxation of fingerprint requisites described described below moves us to 473 hits up from the previous 397!
The newly found websites were all just soulless bulk or mildly cute like the vast majority of them, but I did find found a few new screenshots of CIA websites that targeted other democracies:
I've also decided to now classify garanziadellasicurezza.com (Italy) as a hit due to various forms of supporting evidence being present. The archive is very broken however unfortunately.
The fingerprint of "having a visually similar CQ Counter screenshot" is definitely weaker than a Wayback Machine archive as we only have a screenshot and can't inspect the HTML to find the communication mechanism. But when the screenshot is perfectly in CIA style and in a known IP range, the evidence is too strong and we'll consider it as a hit moving forward.
I'm also going to reclassify a few previously known domains in confirmed IP ranges as hits as hits either when:This is a slight moving of goalposts, but those cases just feel overwhelmingly probably.
- they have Wayback Machine archives with matching visual style
- they have broken Wayback Machine archives but with indication of comms or known HTML elements like rss-item
I love how this project has led me to use whatever random sources come in hand! CQ Counter is the ONLY website that I know of besides the Wayback Machine that has historical screenshots of a huge number of domains. Their database is VERY complete. But they are so obscure!
They even have the old IP of the domain. But because they don't have reverse IP to domain reverse search, and are heavily CAPTCHAed preventing search engines from properly indexing them, we can't use them to fill in existing IP ranges... So the search for the most complete DNS database that doesn't cost 15k USD like DomainTools continues www.reddit.com/r/OSINT/comments/1j8uasm/does_domaintools_offer_historical_reverse_ip_ie/
Interestingly a large number of the websites with broken Wayback Machine are from regions outside of the USA, presumably being slower to load from Wayback Machine US-based servers makes he archives more likely to break.
Updates Backing up CIA website archives for research and posterity Updated 2025-05-23 +Created 2025-05-23
I've downloaded and uploaded copies of the archives of the CIA websites as follows:
- all cqcounter screenshots where cqcounter was the best source to: github.com/cirosantilli/media/tree/master/cia-2010-covert-communication-websites/screenshots/cqcounter. That commercial website does not inspire much trust, e.g. now the main pages like cqcounter.com/site/internationalwhiskylounge.com.html are giving an error:so I'm glad to have saved their precious screenshots at a safer place.
[1114: The table 'access' is full] ( 1114 : The table 'access' is full ) - all Wayback Machine archives to: github.com/cirosantilli/cia-2010-websites-dump. The exports were done with github.com/StrawberryMaster/wayback-machine-downloader by Felipe x.com/opapeldetrouxa which is an up-to-date fork of github.com/hartator/wayback-machine-downloader and the tool seemed to work very well. I've also edited that better working fork at the top answer of: superuser.com/questions/828907/how-to-download-a-website-from-the-archive-org-wayback-machine/957298#957298
The cqcounter dumps don't offer too much information, but having the wayback machine ones could actually reveal new fingerprints and other website information leaks.
Starting December 2004 the "Submit your favored carlson quote" was mind blowingly switched to point to https://washington.serversecured.net/~alljohnn/cgi-bin/memlog.cgi thus likely leaking the control site URL. Beauty. It previously pointed to web.archive.org/web/20040901162621/https://secure.alljohnny.com/cgi-bin/memlog.cgi
mynepalnews.com actually has several archives for a /stats path which contains HTML reports generated by Webalizer, an analytic tracker that tracks the source of incoming traffic!!! It is hard to believe that the CIA would have left that there. Particularly ridiculous is the presence of
inurl:cgi server_software at web.archive.org/web/20110204095809/http://mynepalnews.com:80/stats/usage_200805.html which is almost certainly a Google dork search, which we know is something that the Iranians used to find the websites. That search hits under /cgi-bin/check.cgi. That page is itself os some interest containing SERVER_ADMIN = mmadev@mmadev.com. web.archive.org/web/20110204095815/http://mynepalnews.com:80/stats/usage_200806.html also reveals several request IPs. Even if this is not a CIA website, there's a chance we could find the IP of the Iranian counter-intelligence in these IP list, it's mind blowing. There's lots of referrer spam too as well. Further HTML inspection however seems to show close relationship to that HTML and other confirmed hits.globaltourist.net, if is actually a hit, likely has a a 2003 archive, which would be our earliest hit archive so far.
A fun fact is that looking at the source code of: web.archive.org/web/20130828122833/http://euronewsonline.net/euro_bus.php we noticed an interesting comment:which clarifies that the CIA likely used Adobe ImageReady to cut up the images for Split header images:We also understand that the tool likely outputs the layout to HTML directly, and leaks the adobe projects filenames (.pds files) in the process.
<!-- ImageReady Slices (enewsweather.psd) -->Adobe ImageReady was a bitmap graphics editor that was shipped with Adobe Photoshop for six years. It was available for Windows, Classic Mac OS and Mac OS X from 1998 to 2007. ImageReady was designed for web development and closely interacted with Photoshop

Updates Getting a list of all currencies from Wikidata with SPARQL Updated 2025-05-23 +Created 2024-11-18
This one was way harder than my previous fun with "find the oldest people who won a given prize" (Nobel Prize/Oscar) mastodon.social/@cirosantilli/112689376315990248 because unlike those prizes where all the decisions are centralized, countries are much more complicated beasts, with changing currencies and international recognition.
This was a good experience to see a few ways in which Wikidata is inconsistent, with the same concept being expressed in multiple different ways, e.g. "end time" property of the current vs the superior "end time" qualifier.
Particularly bad is the notion of a "deprecated rank", that should really not exist.
This is exactly the type of semi interactive data munching that I like to do, a bit in the same vein as CIA 2010 covert communication websites and Cool data embedded in the Bitcoin blockchain.
As you might imagine, the secret services use exactly this type of knowledge modelling to do their dirty business, e.g. Gaffer by the GCHQ.
This is the best monstrosity I had the patience to come up with:It got quite close to the ISO 4217 list.

I also had one more fun with: opendata.stackexchange.com/questions/15750/structured-data-for-nobel-prizes/21847#21847 getting some basic info about Nobel Prize winners, and noticed one, John Sulston, 2002 Nobel Prize in Physiology and Medicine laureate, who likely has the wrong place of birth on his Nobel Prize profile: www.nobelprize.org/prizes/medicine/2002/sulston/facts/ which is funny. I suggested the change now. Edit they fixed it after I pointed it out:
Another highlight was 1913 Nobel Prize in Chemistry laureate Alfred Werner who born either in Mulhouse in Alsace, France, or in "Yo no sé qué me pasó" ("I don't know what happened to me" in Spanish), a 1986 song by Mexican singer Juan Gabriel.

Updates Post OurBigBook job search round 2025 Updated 2025-05-23 +Created 2025-05-07 2025-05-23
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.
- prominently seeking funding for OurBigBook on my LinkedIn profile
- CIA 2010 covert communication websites references. This will be my first job hunt since I have published that article. Wish me luck.
- gay Putin profile picture on Stack Overflow
Gay Putin, currently used in Ciro Santilli's Stack Overflow profile
. 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:
- machine learning-adjacent jobs in companies that seem to be doing something that could further AGI, e.g. automatic code generation or robotics would be ideal
- quantum computing
- systems programming, which is what I actually have work experience with
I spent the last two weeks doing that:
- one week browsing everything of interest in London and Paris and sending applications to anything that seemed both relevant and interesting. Maintaining an application list at: Section "Job application by Ciro Santilli".
- one week on a very laborious but somewhat interesting take home exercise for Linux kernel engineer a Canonical, makers of Ubuntu.I had a week to finish 5 practical coding and packaging questions, and I tried to do everything as perfectly as possible, but I somewhat underestimated the amount of work and wait needed to do everything and didn't manage to finish question 4 and missed 5. Oops let's see how that goes.At least this had a few good outcomes for the Internet as I tried to document things as nicely as I could where they were missing from Google as usual:
- I re-tested Linux Kernel Module Cheat and made some small improvements. Things still worked from a Ubuntu 24.10 host (using Docker to Ubuntu 22.04), and I also checked that kernel 6.8 builds and GDB step debugs after adding the newly required config
CONFIG_DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT, also mentioned that at: Why are there no debug symbols in my vmlinux when using gdb with /proc/kcore? - I contributed some simple updates to github.com/martinezjavier/ldd3 getting it closer to work on Linux kernel v6.8. That repository aims to keep the venerable examples from Linux kernel module book LDD3 alive on newer kernels, and is a very good source for kernel module developers.
- How to compile a Linux kernel module?: wrote a quick Ciro-approved tutorial
- Dynamic array in Linux kernel module: I gave an educational example of a dynamic byte array (like std::string) using the kvmalloc family of allocators
- quickemu: this is a good emulator manager and I think I'll be using it for Ubuntu images when needed from now on. I wrote:
- How to run Ubuntu desktop on QEMU?: an introductory tutorial to the software as their README is not that good as is often the case. It's hard for project authors to predict what new users want or not. This is my second answer to this question, the previous one focusing on a more manual approach without third party helpers.
- How to share folder between guest/host? (Quickemu): I explained how to setup a 9p mount to share a directory between guest and host
- Error :: You must put some 'source' URIs in your sources.list: updated this answer for Ubuntu 24.04. This issue comes up when you want to do either of:which don't work by default, and my answer explains how to do it from the GUI and CLI. The CLI method is specially important for Docker images. Since Ubuntu doesn't offer a stable CLI method for this, the method breaks from time to time and we have to find the new config file to edit.
sudo apt build-dep sudo apt source - What is hardware enablement (HWE)?: I learned a bit better how Ubuntu structures its kernel releases for each Ubuntu release
Some of the main issues I had were:- compiling Linux kernel for Ubuntu is extremely slow. I was used to compiling for embedded system with Buildroot, which finishes in minutes, but for Ubuntu is hours, presumably because they enable as many drivers as possible to make a single ISO work on as many different computers as possible, which makes sense, but also makes development harder
- my QEMU setup for Ubuntu was not quite as streamlined and I relearned a few things and set up quickemu. By chance I had recently come across quickemu for testing OurBigBook on MacOS, but I had to learn a bit how to set it up reasonably too
- I re-tested Linux Kernel Module Cheat and made some small improvements. Things still worked from a Ubuntu 24.10 host (using Docker to Ubuntu 22.04), and I also checked that kernel 6.8 builds and GDB step debugs after adding the newly required config
This is the most accessible DNS database online, as it does not require login or payment.
They have reasonable data. It's not fully complete as Ciro Santilli saw on CIA 2010 covert communication websites, but it is very valuable.
Tested as of 2025, they seem to have removed the pre-IP checks on web interface, and just instead use Cloudfare to check that you are human from time to time, which allows for a lot manual searching to be done! Awesome!
Previously, tou could only get about 250 queries on the web interface, then 250 queries per free account via API. They check your IP when you signup, and you can't sign in twice from the same IP. They also state that Tor addresses are blacklisted. They also normalize dots in gmail addresses, so you need more diverse email accounts. But they haven't covered the
.gmail vs .googlemail trick.Their data is also quite disjoint from the data of the 2013 DNS Census. There is some overlap, but clearly their methodology is very different. Some times they slot into one another almost perfectly.
