I found the github and the github.io are very powerful these days, with github I can manage codes with git and download many useful opensource codes, while in github.io I can write some research notes here to share with others.


I have a main domain and blog powered by google blogger which I use to record my thoughts about the daily life in Chinese language. I don’t want to mix the research blog and life blog, so I build a sub domain here. Meanwhile, the markdown language supported by Jekyll is very suitable for write some research notes.


I use the very clear and beautiful theme lagom-orange, thanks for the author james12802 and Matt Swanson.


The Disqus is very good, it is also used in my Chinese blog.

Math Equation

Mathjax, of course, is the first choice. For example the root of equation $ax^2+bx+c=0$ is : \(x_{1,2} = \frac{-b \pm \sqrt{b^2-4ac}}{2a}\)

Code piece

Here is a piece of code in c:

int main()
    printf("hello, world\n");


Maybe I can try write English blog here.
