While this has some of the metrics features that Ciro Santilli wants to implement for OurBigBook.com, it limits the number of articles your readeres can read.
How the fuck can you publish on a website that limits the number of views for your articles?!?! When all it has is static pages + some metrics?!?!
Evil. Just learn to use GitHub Pages for God's sake.

Decent encyclopedia of mathematics. Not much motivation, mostly statements though.
Unlike Wikipedia, they have a more sane forum commenting system, e.g. a page/forum pair:
Wikipedia edit request by Ciro Santilli 40 Updated 2025-07-16
So, it turns out that Wikipedia does have a (ultra obscure as usual) mechanism for pull requests. You learn a new one every day.
Jimmy Wales by Ciro Santilli 40 Updated 2025-07-16
One thing to note is that Jimmy was a finance worker before starting wikipdia, e.g. he had capital to hire Larry Sanger.
Maybe that's the way to go about it, make money first, and later on change the world.
Starting just after the beginning of the Internet can't hurt either. Though tooling must have been insane back then.
Coursera by Ciro Santilli 40 Updated 2025-07-16
Some courses at least allow you to see material for free, e.g.: www.coursera.org/learn/quantum-optics-single-photon/lecture/UYjLu/1-1-canonical-quantization. Lots of video focus as usual for MOOCs.
It is extremely hard to find the course materials without enrolling, even if enrolling for free! By trying to make money, they make their website shit.
The comment section does have a lot of activity: www.coursera.org/learn/statistical-mechanics/discussions/weeks/2! Nice. And works like a proper issue tracker. But it is also very hidden.
SmartNIC by Ciro Santilli 40 Updated 2025-07-16
A network interface controller that does more than just the base OSI model protocols, notably in a programmable way.

Kaplansky's theorem on projective modules, formulated by David Kaplansky, provides a significant result in the theory of modules over rings. The theorem states that any projective module over a ring is a direct summand of a free module if and only if the ring is a certain type of ring known as a "Baer ring.

The term "supermodule" can refer to different concepts depending on the context in which it is used. Here are a few interpretations: 1. **Mathematics**: In the context of algebra, specifically in module theory, a "supermodule" typically refers to a module over a superring or a Z-graded ring. A supermodule has a decomposition into even and odd parts, which is important in the context of supersymmetry in theoretical physics and other areas of advanced mathematics.
Class II genes typically refer to a category of genes involved in the immune system, particularly those that encode for Major Histocompatibility Complex (MHC) class II molecules. MHC class II molecules play a crucial role in the immune response by presenting antigens to CD4+ T cells, which are key players in the adaptive immune system.
The Cycle of Quantification and Qualification refers to a framework used in various fields, including research, project management, and quality assurance, to assess and improve the performance or quality of processes, products, or services. Here's a breakdown of the concepts: 1. **Quantification**: This involves measuring and analyzing data to obtain numerical values that can represent performance, quality, or other relevant metrics. Quantification provides a factual basis for understanding how well something is functioning.
A hypersensitive site, often referred to in the context of molecular biology and genetics, is a region of DNA that exhibits a heightened level of sensitivity to digestion by certain nucleases, such as DNase I. These regions are typically associated with active regulatory elements, such as enhancers, promoters, and transcription factor binding sites.

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 2.
    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
