Ciro Santilli 37 Created 2024-07-29 Updated 2025-07-16A dimension in a system of units is something like length, weight or time, without considering how to assign numerical values ot them, which requires units of measurement such as the meter, kilogram or second.
Talking about dimensions can be useful when explaining new derived units without worrying about the exact units involved. See e.g. this table: en.wikipedia.org/w/index.php?title=Lumen_(unit)&oldid=1233810964#SI_photometric_units
Stack Overflow does have an super naive reputation and moderation system and overly restrictive subject matter, which Ciro Santilli wants to improve upon with OurBigBook.com.
However, it is the best that we have now, and if you use it like Ciro, you won't get tired:What else would you expect from a naive algorithm system that has 10 million newbies asking stuff?
- monitor only rare tags that you know a lot about, let others answer duplicates on big tags for you
- only answer on bigger tags when you find a better answer than can be found on the page
- accept that sometimes things are bound to go wrong, that reputation is meaningless, and move on
The key problem of Stack Overflow is closurism. The answer close feature is just not made for purpose. The sole purpose of "closing" should be to prevent easy reputation farming. What it should do instead, is remove points gained from duplicates and off topic questions. But it should not prevent new answers. The disk space costs nothing, and Google doesn't care about the closed status of a question.
As of 2024, the only competitor of Stack Overflow is Reddit (besides LLMs, which do nothing but extract data from those two and other sites). Reddit removed the mandatory thread locking after 6 months, but still lacks the Q&A focus required for greatness. Its community however is much more chill and doesn't close and downvote the fuck out of everything.

Ciro Santilli 37 Created 2024-07-29 Updated 2025-07-16 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!
Intro to OurBigBook
. Source. 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.
