Home Page

This site is basically my English blog. The main topics will include programming, mathematics, and online courses review.

My Chinese blog is "www.ran-blog.com." The main difference between these two websites are:

  • "www.ranblog.com" is more about teaching something that I have already been familiar with.
  • "www.ran-blog.com" is more about documenting what I have learned.

Regarding membership, you can read this article.
