Ciro's Edict #8 Article metadata shown next to every header Updated 2025-07-01 +Created 1970-01-01
This is a major feature: we have now started to inject the following buttons next to every single pre-rendered header:
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.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.
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.
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.
- what is the best content for subject X.For example, if you are reading
cirosantilli/riemann-integral
and it is crap, you would be able to click the buttonwhich leads you to the URL: ourbigbook.com/subject/mathematics. This URL then contains a list of all pages people have written about the subjectVersions by other authors
mathematics
, sorted by some algorithm, containing for example: - who knows the most about subject X. This can be found by visiting: ourbigbook.com/users/mathematics "Top Mathematics users", which would contain the list of users sorted by the algorithm:
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).

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:and for the second smaller one:the third one being an OP_RETURN message.

This event received some coverage:
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 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.
Somewhat midway between a syllabary and an alphabet: you write out consonants, and vowels are "punctuation-like-modifiers".
There are unlisted articles, also show them or only show them.
