Check out: OurBigBook.com, the best way to publish your scientific knowledge. 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: 100k USD = I quit me job and work on it one year full time. Status: ~144k / 200k USD reached: 1st year locked-in, 2nd year stretch goal open at 200k USD. 1M USD = I retire and do it forever. How to donate: Section "Sponsor Ciro Santilli's work on OurBigBook.com".
I reached 100k USD after a 1000 Monero donation, so I quit my job for 1 year starting 1st June 2024 to solve as many STEM courses as I can from a world leading university to try and kickstart The Higher Education Revolution. If I reach 200k USD, then I'll do it for two years instead. A second year greatly improve chances of success: year one I solve a bunch of courses, year two I come guns blazing with the content 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.

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.
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:

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?".
Figure 4.
YellowRobot.jpg
. Source.
JPG 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:
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
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.
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.

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.
Figure 6.
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.

Birch and Swinnerton-Dyer conjecture in two minutes by Ciro Santilli

He put it there after working a bit on Section "How to use an Oxford Nanopore MinION to extract DNA from river water and determine which bacteria live in it" :-) And he would love to document more experiments like that one Section "Videos of all key physics experiments", but opportunities are extremely rare.
A quick 2D continuous AI game prototype for reinforcement learning written in Matter.js, you can view it on a separate page at cirosantilli.com/_raw/js/matterjs/examples.html#top-down-asdw-fixed-viewport. This is a for-fun-only prototype for Ciro's 2D reinforcement learning games, C++ or maybe Python (for the deep learning ecosystem) seems inevitable for a serious version of such a project. But it is cute how much you can do with a few lines of Matter.js!

    "The Hashling" presumably refers to a cute fictional crab-like animal that somehow inhabits the alternate reality created Blockchain network's incredible hashrate. Yet another soulless NFT collection would later be created with that name as well: magiceden.io/ordinals/marketplace/hashlings.
    But that is not all! Immediately after the ASCII art encoded as one constant, the remaining constants of the input script except for the last one encode a raw PNG image with a hand drawing of the creature:
    https://raw.githubusercontent.com/cirosantilli/media/master/bitcoin-inscription-indexer/data/bin/a96bda1363e8968f45b05e3c1940ba37b18de53de0157d453ca9bfc44913768c.png
    The last constant is then the only thing that matters and spends the incoming output.
    The ASCII art and image are also inscribed 16 more times on the blockchain: github.com/cirosantilli/bitcoin-inscription-indexer/blob/master/data/hashling. 453c9511ca76361c8c44b4302ce1b5d8d5c98a938b548478ef931baaa7d70e62 also has the image without any ASCII strings.
    Peter Todd is the author of Peter Todd's hash collision puzzles. @BraveTheWorld is presumably twitter.com/BraveTheWorld, but it is less clear what are they.

    and we've decoded it manually in Vim.
    Both blocks were mined by AntPool, so they weren't mining themselves to enforce ordering. So how is ordering assured? TODO are transactions actually contiguous in the block or are there other transactions interspersed? According to:
    bitcoin-core.cli getblock 00000000000000000baf6e3006fd05a1c5dbca3d430012180f8098cbe8b8ce22
    many of the transactions are contiguous but we haven't checked all of them.

    The message is encoded with OP_RETURN payloads across multiple transactions, 40 bytes per transaction. They actually managed to upload two almost fully consecutive transaction blocks and in the correct order. Could they be miners?
    Some of the payloads contain newlines, you are just supposed to paste all payloads together to form the image. Our reconstruction here is manual however, lazy to script it properly.

    vaardig regulerend de orde van de dag
    Is in Dutch of course, literally:
    skillfully regulating the order of the day
    Given the date and language, it appears to be a reference to Koningsdag, Dutch national holiday that celebrated the birthday of their King at the time, King Willem-Alexander. Born in 1956, he would have been turning 60 at the time, so a nice round number in 2016 when these birthday candles were inscribed.

    .
    Contains ASCII art of a large letter A. Has some custom encoding we didn't have the time to investigate which makes it deformed in our dumps, so we fixed it manually. The associated message reads:
    !Study Math and Computer Science at Augustana College!
    and so we understand that the ASCII art is formatted to look like the font of the logo of that university from Illinois.

Lines are completely scrambled, so either there is an index somewhere, or it was meant as a puzzle. This is the best we've managed to unscramble so far:

    At firs we thought it was some kind of tribute to the Cannes Film Festival, but given the string "Titanium" and the fact that all people mentioned on another section of the art work for advertisement companies, we understand that it is instead almost certainly about the "Cannes Lions International Festival of Creativity", previously "International Advertising Festival", which has a "titanium" prize category, e.g. as mentioned at: www.thedrum.com/news/2018/06/22/cannes-lions-winners-titanium-glass-grand-prix-good-and-more:
    The highly coveted Titanium Lions - created to honor marketing work that doesn't fit neatly into traditional categories
    The part with the at signs '@' which we believe represents the lion is the hardest one and we've perhaps gotten some lines wrong, corrections are welcome.

    The actual code appears to be:
    OPRETURNISMYFRIEND
    a reference to OP_RETURN. It is steganographically encoded diagonally across the skull's eyes. Ciro Santilli only saw this after grepping:
    grep @ data/out/0538.txt
    which made all non @ signs stand out due to the terminal's syntax highligh. This image was uploaded one line per transaction with a few interruptions that we removed manually, and there were was a previous partial attempt a bit before: at tx f8102999c0aaf7681deec383eb8e7946f093e94a116a21e367e9ed6b7c32d1fb so either a failure, or maybe it was intentional to obfuscate things a bit.

    The website is also mirrored at yiping.de. The navigation is a bit confusing, but yang.yiping.de/?cat=10 contains a blog with many entries, presumably by her husband
    • the first post is from slightly before her death on 2020-09-01 and documents their 2019 trip to San Francisco apparently to visit family. She could be a COVID-19 casualty.
    • yang.yiping.de/?p=367 gives transliterated names of her three children: Kaibin, Ella and Martin
    • yang.yiping.de/?p=638 has some mentions of work colleagues, but not enough to easily identify where she worked

    ZN inscription
    .
    This ASCII art had been previously noted by sroose and decoded by brando2131 on Reddit, and was brought to our attention by Bagfoot OP446 on twitter. Ciro Santilli had previously spotted the art, but failed to decode it. "ZENON NETWORK" is inscribed just after the art confiming the meaning of the characters, but it does not appear in our ASCII dumps presumably because the string it is too short and surrounded by non-ASCII.
    Each line is encoded with OP_RETURN, is 38 bytes long, and starts and ends in 6 spaces, leading to 26 non-whitespace characters per line. The lines appear in scambled order and it is unclear if there is any logic in the ordering or if it was just meant as a little puzzle. But given the nearby "ZENON NETWORK" inscription, this decoding is overwhelmingly likely correct.
    The following lines also show up in our ASCII dump:
      ;4Fdzw1k=zzzzzzzzzzzzzzzz;      
  ,vtv3f5aKY0jGQglP9a1AGw==.      
  ;BynQtpeUyWTXKGTrGhdV2Q==;      
  ;tVMd3L1CKM4wFmyxEEEUV2bY;
    They seem like Base64 encoded data due to the = sign padding, but nothing human readable comes out of them, so their meaning remains currently unknown.

Force of Will Updated 2025-02-22 +Created 1970-01-01
View more
ASCII art of a Force of Will, a famous and powerful Magic: The Gathering card first printed in 1996.
This is Ciro Santilli's personal favorite ASCII art he has found in the blockchain so far. Also Ciro could not find any other previous source of this, so there is some chance it is original. One can dream.
The choice of card is probably linked to the function of the card in the game of Magic: The Gathering. This card essentially prevents the opponent from casting a spell they are about to cast. The presumed intended meaning of this art is further accentuated by the old card type term "interrupt" (late renamed to "instant"), which suggests that "this ASCII art is an interruption to the normal monetary transactions of the blockchain".
One of also reminded of the prayer wars interruption attempts. We could not however identify anything specific that this ASCII art might have tried to interrupt besides the normal flow of monetary transactions.
If one goes full art critic mode, it is also tempting to draw a parallel between the card's "You may pay 1 life" alternative casting cost (as opposed to 5 mana, 3 and two blue, which is a very large cost for most games) as being a reference to the money spent by the uploader of the art to upload it.
TODO understand exactly how it was encoded and why it is so weird. The UUUU has a slightly weird encoding which we fixed by hand here TODO understand.

The associated message contains the Arecibo message as ASCII 0's and 1's. When properly cut at the newlines, they draw the message as ASCII art, as the original Arecibo encoding intends, here's a version with the 0's replaced by spaces to make it more readabale:

Cycle graph (algebra) Updated 2025-02-22 +Created 1970-01-01
View more
How to build it: math.stackexchange.com/questions/3137319/how-in-general-does-one-construct-a-cycle-graph-for-a-group/3162746#3162746 good answer with ASCII art. You basically just pick each element, and repeatedly apply it, and remove any path that has a longer version.
Immediately gives the generating set of a group by looking at elements adjacent to the origin, and more generally the order of each element.
TODO uniqueness: can two different groups have the same cycle graph? It does not seem to tell us how every element interact with every other element, only with itself. This is in contrast with the Cayley graph, which more accurately describes group structure (but does not give the order of elements as directly), so feels like it won't be unique.

FFmpeg filter graph Updated 2025-02-22 +Created 1970-01-01
View more
Filter graphs are a thing of great beauty. What an amazingly obscure domain-specific language, but which can produce striking results with very little!!!
ffplay -autoexit -nodisp -f lavfi -i '
sine=frequency=500[a];
sine=frequency=1000[b];
[a][b]amerge, atrim=end=2
'
which creates a graph:
                              +--------+
[sine=frequency=500]--->[a]-->|        |
                              | amerge |-->[atrim]-->[output]
[sine=frequency=1000]-->[b]-->|        |
                              +--------+
and plays 500 Hz on the left channel and 1000 Hz on the right channel for 2 seconds.
So we see the following syntax patterns:
  • sine, amerge and atrim are filters
  • sine=frequency=500: the first = says "araguments follow"
    • frequency=500 sets the frequency argument of the sine filter
    • for multiple arguments the syntax is to separate arguments with colons e.g. sine=frequency=500:duration=2
  • ;: separates statements
  • [a], [b]: sets the name of an edge
  • ,: creates unnamed edge between filters that have one input and one output
A list of all filters can be obtained ith:
ffmpeg -filters
and parameters for a single filter can be obtained with:
ffmpeg --help filter=sine

Nested set model Updated 2025-02-22 +Created 1970-01-01
View more
This is particularly important in SQL: Nested set model in SQL, as it is an efficient way to transverse trees there, since querying parents every time would require multiple disk accesses.
As a tree:
  • Root 1
    • Child 1.1
      • Child 1.1.1
      • Child 1.1.2
    • Child 1.2
      • Child 1.2.1
      • Child 1.2.2
As the sets:
 __________________________________________________________________________
|  Root 1                                                                  |
|   ________________________________    ________________________________   |
|  |  Child 1.1                     |  |  Child 1.2                     |  |

|  |________________________________|  |________________________________|  |
|__________________________________________________________________________|
Consider the following nested set:
0, 8, root
  1, 7, mathematics
    2, 3, geometry
      3, 6, calculus
        4, 5, derivative
        5, 6, integral
      6, 7, algebra
  7, 8, physics
When we want to insert one element, e.g. limit, normally under calculus, we have to specify:
  • parent
  • index within parent
so we have a method:

Satoshi uploader Updated 2025-02-22 +Created 1970-01-01
View more
By "Satoshi uploader" we mean the data upload script present in tx 4b72a223007eab8a951d43edc171befeabc7b5dca4213770c88e09ba5b936e17 of the Bitcoin blockchain.
The uploader, and its accompanying downloader, are Python programs stored in the blockchain itself. They are made to upload and download arbitrary data into the blockchain via RPC.
These scripts were notably used for: illegal content of block 229k. The script did not maintain its popularity much after this initial surge up loads, likely all done by the same user: there are very very few uploads done after block 229k with the Satoshi uploader.
Our choice of name as "Satoshi uploader" is copied from A Quantitative Analysis of the Impact of Arbitrary Blockchain Content on Bitcoin by Matzutt et al. (2018) because the scripts are Copyrighted Satoshi Nakamoto on the header comment, although as mentioned at Hidden surprises in the Bitcoin blockchain by Ken Shirriff (2014) this feels very unlikely to be true.
A more convenient version of those scripts that can download directly from blockchain.info without the need for a full local node can be found at: github.com/cirosantilli/bitcoin-inscription-indexer/blob/master/download_tx_consts.py by using the --satoshi option. E.g. with it you can download the uploader script with:
./download_tx_consts.py --satoshi 4b72a223007eab8a951d43edc171befeabc7b5dca4213770c88e09ba5b936e17
mv 4b72a223007eab8a951d43edc171befeabc7b5dca4213770c88e09ba5b936e17.bin uploader.py
The scripts can be found in the blockchain at:
The uploader script uses its own cumbersome data encoding format, which we call the "Satoshi uploader format". The is as follows:
  • ignore all script operands and constants less than 20 bytes (40 hex characters). And there are a lot of small operands, e.g. the uploader itself uses format www.blockchain.com/btc/tx/4b72a223007eab8a951d43edc171befeabc7b5dca4213770c88e09ba5b936e17 has a OP_1, data, OP_3, OP_CHECKMULTISIG pattern on every output script, so the OP_1 and OP_3 are ignored. I.e., it is P2FMS.
  • ignore the last output, which contains a real change transaction instead of arbitrary data. TODO why not just do what with the length instead?
  • the first 4 bytes are the payload length, the next 4 bytes a CRC-32 signature. The payload length is in particular useful because of possible granularity of transactions. But it is hard to understand why a CRC-32 is needed in the middle of the largest hash tree ever created by human kind!!! It does however have the adavantage that it allows us to more uniquely identify which transactions use the format or not.
This means that if we want to index certain file types encoded in this format, a good heuristic is to skip the first 9 bytes (4 size, 4 CRC, 1 OP_1) and look for file signatures.
Let's try out the downloader to download itself. First you have to be running a Bitcoin Core server locally. Then, supposing .bitcon/bitoin.conf containing:
rpcuser=asdf
rpcpassword=qwer
server=1
txindex=1
we run:
git clone git://github.com/jgarzik/python-bitcoinrpc.git
git -C python-bitcoinrpc checkout cdf43b41f982b4f811cd4ebfbc787ab2abf5c94a
