Setting up a blog

I am configuring this blog if I want to communicate, write or document things using markdown and figures. This post is to test if I can write some code with syntax highlight and some math.

Here’s an example c++ code:

// hi.cpp
#include <iostream>
int
main(int argc, const char **argv) {
  // prints hi to stdout
  std::cout << "Your program has " << argc << " arguments" << std::endl;
  return 0;
}

This is how to compile it:

$ g++ -O3 -Wall -o hi hi.cpp

And this is how you run it

$ ./hi arg1 arg2 arg3
Your program has 4 arguments

This is a path to a link, and below is an equation:

\[x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}\]
