This section is about functions that operate on numbers such as the integers or real numbers.
Ahh, this brings good memories of Ciro Santilli's musical formative teenage years scouring the web for the best art humanity had ever produced in certain generes. And it still is a valuable resource as of the 2020's!

Ciro Santilli 35 Updated 2025-01-21 +Created 1970-01-01Some people have been creating YouTube channels that just post and go over a large number of Stack Exchange questions, some of them with a quick random intro video. Perfectly legal due to CC BY-SA but really weird stuff!
- Roel Van de Paar www.youtube.com/@RoelVandePaar. This one seems to be the OG. As of June 2024 it had 2M videos (!), 161K subscribers and only 47M views. youtube.fandom.com/wiki/Roel_Van_de_Paar mentions "he has the highest number of uploads of any YouTube channel". Interestingly at www.linkedin.com/in/roelvandepaar/?originalSubdomain=au he says he is a test engineer at MariaDB.
- Peter Schneider www.youtube.com/@peterschneiderQandA e.g. www.youtube.com/watch?v=GBQhrKRpUdI "How to put a newline special character into a file using the echo command and redirection operator?" from unix.stackexchange.com/questions/191694/how-to-put-a-newline-special-character-into-a-file-using-the-echo-command-and-re)Stackexchange
- Sophia Wagner www.youtube.com/@SophiaWagnerQandA. As of June 2024 it had 14k videos and only 88k views, so she made 88 bucks on it.
- E.g. www.youtube.com/watch?v=elIlkJneVBI "Vertically stack multiple images using ImageMagick" goes over superuser.com/questions/290656/vertically-stack-multiple-images-using-imagemagick
- www.youtube.com/@LukeChaffeyTechInfo Luke Chaffey, an Indian-American dude, e.g. www.youtube.com/watch?v=wmx6mN_G83s "Do Boost Geometry nearest queries always sort results ordered by smallest distance first?"
- www.youtube.com/@pythonoracle The Python Oracle. Speech synthesis, with different accents. Cute!
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:
- 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-calculusArticles 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.

View it live at: ourbigbook.com/go/topic/derivative - 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.
- to OurBigBook.com to get awesome multi-user features like topics and likes
- as HTML files to a static website, which you can host yourself for free on many external providers like GitHub Pages, and remain in full control
