About me

I am Chen-Pang He (何震邦), studying medicine in Taipei Medical University.

I started writing web pages since 2000 and fell in love with C++ in high school. I tried to make some software of numerical linear algebra on my own, but aborted upon meeting Eigen and improved its modules of matrix function and of Kronecker product.

About this site

This site is to help Integration by me, whose content is in mathematics and computer science.

I set up this site becuase GitHub Pages uses Jekyll, enabling me to write modularized stylesheets in Sass, which can also be loaded across sites.

On this site, content is under CC BY-SA 4.0, source code under GPLv3+, but the upstream is under more permissive MIT License. I choose free media as possible.

If you have no time for these tl;dr licenses, you only have to remember that this site is free software. You have the Four Freedoms:

  1. The freedom to run the program as you wish, for any purpose
  2. The freedom to study how the program works, and change it so it does your computing as you wish. Access to the source code is a precondition for this.
  3. The freedom to redistribute copies so you can help your neighbor.
  4. The freedom to distribute copies of your modified versions to others. By doing this you can give the whole community a chance to benefit from your changes. Access to the source code is a precondition for this.
