Ciro Santilli 40 Updated 2025-07-16TODO what does this Chinese forum track? New registrations? Their focus seems to be domain name speculation
Some of the threads contain domain dumps. We haven't yet seen a scrapable URL pattern, but their data goes way back and did have various hits. The forum seems to have started in 2006: club.domain.cn/forum.php?mod=forumdisplay&fid=41&page=10127
club.domain.cn/forum.php?mod=viewthread&tid=241704 "【国际域名拟删除列表】2007年06月16日" is the earliest list we could find. It is an expired domain list.
Some hits:

The problem as with many well known science communicators is that he falls too much on the basic side of the the missing link between basic and advanced.
The Lossy Counting Algorithm is a streaming algorithm designed for the estimation of frequency counts of items in a data stream. It's particularly useful when dealing with large volumes of data where it is impractical to store and count each individual element due to memory constraints. The primary goal of the Lossy Counting Algorithm is to maintain an approximate count of elements that may exceed a certain frequency threshold.

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.

- 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
