WordNet by Ciro Santilli 37 Updated 2025-07-16
Groups concepts by hyponymy and hypernymy and meronymy and holonymy. That actually makes a lot of sense! TODO: is there a clear separation between hyponymy and meronymy?
Browse: wordnetweb.princeton.edu/perl/webwn Appears dead as of 2025 lol.
The online version of WordNet has been deprecated and is no longer available.
Does not contain intermediat scientific terms, only very common ones, e.g. no mention, of "Josephson effect", "photoelectric effect"

Two Minute Papers by Ciro Santilli 37 Updated 2025-07-16
The approach of this channel of exposing recent research papers is a "honking good idea" that should be taken to other areas beyond just machine learning. It takes a very direct stab at the missing link between basic and advanced!
Memory semantics by Ciro Santilli 37 Updated 2025-07-16
These are the rules which specify what different concurrent read/write memory accesses from different threads/processes can or cannot see.
Notable such set of rules include:
The art of programming by Ciro Santilli 37 Updated 2025-07-16
Just art:
  • useless mathy stuff
  • incredibly nifty little tools that are just so satisfying to use it is mind blowing:
  • media related stuff
Automatic programming by Ciro Santilli 37 Updated 2025-10-18
We use the term "automatic programming" to mean "generating code from natural language".
The ultimate high level of which is of course to program with:which is basically the goal of artificial general intelligence, especially according to The Employment Test definition of AGI.
The term has not always had that sense:
automatic programming has always been a euphemism for programming in a higher-level language than was then available to the programmer
sums it up.
But in the current AI boom, this is the sense that matters, so that's what we will go with.
Lowering and raising by Ciro Santilli 37 Updated 2025-07-16
Lowering means translating to a lower level representation.
Raising means translating to a higher level representation.
Decompilation is basically a synonym, or subset, of raising.

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
