Cirocoin by Ciro Santilli 37 Updated 2025-07-16
Good pious Cirists earn Cirocoins.
Cirocoins are the most valuable form of currency that exists at any point.
Cirocoins can only be issued by Ciro Santilli.
Cirocoins are strictly nominal, and cannot be traded by recipients with anyone but Ciro, i.e. they are extremely illiquid.
Cirocoins can be removed from recipients at any point if they commit non-Cirist acts.
It is not possible to give a precise number to how many Cirocoins anyone owns. This is decided on a transaction by transaction basis. Ciro can therefore only inform you if your Cirocoin balance increased or decreased, but any attached number has no value, and thus are equivalent to expressions of type "you gained/lost a Cirocoin".
The following inferior currencies come to mind:

C plus plus is what you get when you want to have all of:
  • ability to write DRY code, which is e.g. impossible in the C
  • low level control, notably not having garbage collection, as possible in the C
  • somewhat backwards compatibility with C
In category theory, a **section** is a concept that arises in the context of functors, particularly when dealing with object mappings between categories. More formally, a section refers to a right inverse to a morphism. Here’s a more detailed breakdown of what this means: 1. **Categories and Functors**: In category theory, a category consists of objects and morphisms (arrows) between those objects.
Red rot is a term that can refer to a couple of distinct issues depending on the context, but it is most commonly associated with two main areas: 1. **In Plant Pathology:** Red rot is a disease that affects plants, particularly sugarcane and other grasses. It is caused by the fungus **Colletotrichum falcatum** and is characterized by the decay of plant tissues and a reddish discoloration of the affected areas.
"Free drift" can refer to different concepts depending on the context, but in a general sense, it often describes a state where something is allowed to move or operate without restraint or control.
These are websites that offer somewhat overlapping services, many of which served inspirations, and why we think something different is needed to achieve our goals.
Notably, OurBigBook is the result of Ciro Santilli's experiences with:
OurBigBook could be seen as a cross between those three websites.
Quick mentions:
Static website-only alternatives:
In this section we will gather some more advanced ideas besides the basic features described at how the website works.

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.
    Figure 5. . You can also edit articles on the Web editor without installing anything locally.

  4. Infinitely deep tables of contents:

    Descendant pages can also show up as toplevel e.g.: ourbigbook.com/cirosantilli/chordate-subclade
All our software is open source and hosted at: github.com/ourbigbook/ourbigbook
