Political correctness by Ciro Santilli 40 Updated 2025-07-16
Ciro Santilli believes it generally hurts more than it helps.
Especially when you can't even mention censored things to criticize them. You have to pretend they never existed. So people will forget about them, and do them again in the future.
And when companies do it just to look good, even though it has absolutely no real impact on the lives of those who are discriminated against.
This section tries to explain how the discoveries were made in more detail.
Some of the subsections are quite readable, while others are mostly data dumps and work logs, so bear with us.
Here we list of suspected domains for which the correct IP was apparently not found since there are no neighbouring hits.
These are suspicious, and suggest either that we didn't obtain the correct reverse IP, or a change in CIA methodology from an older time at which they were not yet using the obscene IP ranges.
For example, in the case of inews-today.com, 2013 DNS Census gave one IP 193.203.49.212, but then viewdns.info gave another one 66.175.106.146 which fit into an existing IP range, and which assumed to be the correct IP of interest.
A similar case happened when we found IP 212.209.74.126 for headlines2day.com with dnshistory.org: dnshistory.org/historical-dns-records/a/headlines2day.com.
It is also possible that some of them are simply false positives so they should be taken with a grain of salt. Further reverse engineering e.g. of comms or HTML analysis might be able to exclude some of them.
It is interesting to note that Reuters seems to have featured disproportionately many hits from that range, one wonders why that happened. It is possible that they chose these because they actually didn't have any nearby hits to give away less obvious information, though they did pick some from the ranges as wel.
In what follows we list the domains with possible reverse IPs and what was explored so far for each. We consider IPs not in a range to be uncertain, and that instead their domains might have been previously in a range which we

This is a dark art, and many of the sources are shady as fuck! We often have no idea of their methodology. Also no source is fully complete. We just piece up as best we can.
In order to explore IPs in known IP ranges, what we need are good DNS databases.
Does not appear to have any reverse IP hits unfortunately: opendata.stackexchange.com/questions/1951/dataset-of-domain-names/21077#21077. Likely only has domains that were explicitly advertised.
We could not find anything useful in it so far, but there is great potential to use this tool to find new IP ranges based on properties of existing IP ranges. Part of the problem is that the dataset is huge, and is split by top 256 bytes. But it would be reasonable to at least explore ranges with pre-existing known hits...
We have started looking for patterns on 66.* and 208.*, both selected as two relatively far away ranges that have a number of pre-existing hits. 208 should likely have been 212 considering later finds that put several ranges in 212.

Starting at twitter.com/shakirov2036/status/1746729471778988499, Russian expat Oleg Shakirov comments "Let me know if you are still looking for the Carson website".
He then proceeded to give Carson and 5 other domains in private communication. His name is given here with his consent. His advances besides not being blind were Yandexing for some of the known hits which led to pages that contained other hits:
Unfortunately, these methods are not very generalizable, and didn't lead to a large number of other hits. But every domain counts!
Added ourbigbook --format-source automatic code formatting. I implemented it for the following reasons:
  • I want to do certain automatic modifications to source code on web, e.g.:
    • allow users to select the parent article of a new article on the web UI, but that is currently doable only with \Include macros
    • allow users to edit the source only for a specific header
  • later on, much later, this will allow WYSIWYG export to plaintext
This also ended up having one unexpected benefit: whenever a new feature is added that deprecates an old feature, by converting the large corpus from github.com/cirosantilli/cirosantilli.github.io to the new feature I can test the new preferred feature very well.
For example, converting \x[blue cat] en masse to the new insane syntax <blue cat> found several bugs with the new insane syntax.
This seemed somewhat easy at first, so I started it as a way of procrastinating more urgent Web features (web scares me, you know), but it ended being insanely hard to implement, because there are many edge cases. Also, most bugs are not acceptable, as they would corrupt your precious source code and potentially output.
But well, it is done!

Whichever problem you present a German, they will look for a mechanical solution to it!
Diophantine equation by Ciro Santilli 40 Updated 2025-07-16
Sometimes systems of Diophantine equations are considered.
Problems generally involve finding integer solutions to the equations, notably determining if any solution exists, and if infinitely solutions exist.
The general problem is known to be undecidable: Hilbert's tenth problem.
The Pythagorean triples, and its generalization Fermat's last theorem, are the quintessential examples.
Lorentz covariance by Ciro Santilli 40 Updated 2025-07-16
Same motivation as Galilean invariance, but relativistic version of that: we want the laws of physics to have the same form on all inertial frames, so we really want to write them in a way that is Lorentz covariant.
This is just the relativistic version of that which takes the Lorentz transformation into account instead of just the old Galilean transformation.
Distributive property by Ciro Santilli 40 Updated 2025-07-16
One of the defining properties of algebraic structure with two operations such as ring and field:
This property shows how the two operations interact.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.

    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
