Gifted education by Ciro Santilli 37 Updated +Created
If school weren't bullshit, 99% of students would be in gifted education for what they truly love and are good at.
What is sad about many programs is that they are exclusivist and non scalable, selecting people some how and non scalably educating them. We need a more "here's some projects let's do them whoever can" approach to things, maybe like Google Summer of Code.

One thing that annoys Ciro Santilli about that website are the footnote overload. Ciro likes linear things.

Crystal radio by Ciro Santilli 37 Updated +Created
This was the first generation of commercially successful radios.
It uses a crystal detector as its diode, which is a crucial element of the radio, thus its name.
They were superseded by transistor radios, which were much more reliable, portable and could amplify the signal received.

Automated theorem proving by halting problem reduction by Ciro Santilli 37 Updated +Created
If you can reduce a mathematical problem to the Halting problem of a specific turing machine, as in the case of a few machines of the Busy beaver scale, then using Turing machine deciders could serve as a method of automated theorem proving.
That feels like it could be an elegant proof method, as you reduce your problem to one of the most well studied representations that exists: a Turing machine.
However it also appears that certain problems cannot be reduced to a halting problem... OMG life sucks (or is awesome?): Section "Turing machine that halts if and only if Collatz conjecture is false".

@cirosantilli/_file/webpack/webpack/no-js-inject by Ciro Santilli 37 Updated +Created
This example shows how you could manually include the dist/index.js that is output from webpack into your index.html.
This is generally not what you want to do, because what you actually want to do is to use a Js output name with a hash in it, so that browsers only need to refetch when the name changes.
And to do that, we have to let webpack dynamically inject that unpredictable hash as done in webpack/template with:
new HtmlWebpackPlugin({
  filename: 'index.html',
  // Inject the include to our hashed filename,
  // since it is not deterministic due to the hash.
  inject: true,
  template: path.resolve(__dirname, 'index.html'),
}),

E. Coli K-12 MG1655 gene of unknown function by Ciro Santilli 37 Updated +Created
UniProt for example describes YaaX as "Uncharacterized protein YaaX".
As function is discovered, they then change it to a better name, e.g. to names such as the E. Coli K-12 MG1655 transcription unit thrLABC proteins all of which have a clear name due to threonine.
There are many other y??? as of 2021! Though they do tend to be smaller molecules.

CIA 2010 covert communication websites / CGI comms by Ciro Santilli 37 Updated +Created
We've come across a few shallow and stylistically similar websites on suspicious ranges with this pattern.
No JS/JAR/SWF comms, but rather a subdomain, and an HTTPS page with .cgi extension that leads to a login page. Some names seen for this subdomain:
  • secure.: most common
  • ssl.: also common
  • various other more creative ones linked to the website theme itself, e.g.:
    • musical-fortune.net has a backstage.musical-fortune.net
The question is, is this part of some legitimate tooling that created such patterns? And if so which? Or are they actual hits with a new comms mechanism not previously seen?
The fact that:
  • hits of this type are so dense in the suspicious ranges
  • they are so stylistically similar between on another
  • citizenlabs specifically mentioned a "CGI" comms method
suggests to Ciro that they are an actual hit.
In particular, the secure and ssl ones are overused, and together with some heuristics allowed us to find our first two non Reuters ranges! Section "secure subdomain search on 2013 DNS Census"

Pinned article: ourbigbook/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.
    Figure 5. . You can also edit articles on the Web editor without installing anything locally.
