You’ll find this post in your _posts directory. Go ahead and edit it and re-build the site to see your changes. You can rebuild the site in many different ways, but the most common way is to run jekyll serve, which launches a web server and auto-regenerates your site when a file is updated.

To add new posts, simply add a file in the _posts directory that follows the convention YYYY-MM-DD-name-of-post.ext and includes the necessary front matter. Take a look at the source for this post to get an idea about how it works.

Code

Jekyll also offers powerful support for code snippets:

ruby

def print_hi(name)
  puts "Hi, #{name}"
end
print_hi('Tom')
#=> prints 'Hi, Tom' to STDOUT.

python

from numpy import np
import matplotlib.pyplot as plt
x = np.range(10)
y = np.sin(x)
plt.plot(x, y)
plt.show()

C++

int main()
{
 return 0;
 }

Math

The time mean velocity $\langle v \rangle_{\Delta t}$ is defined as the mean value of the instantaneous velocities $N_{\Delta t}$ pedestrians. $v_i(t)$ is calculated by use of the displacement of pedestrian $i$ in a small time interval $\Delta t^\prime$ around $t$:

$v_i(t)=\frac{\vec{x_i}(t+\Delta t^\prime/2)-\vec{x_i}(t-\Delta t^\prime/2))}{\Delta t^\prime}.$
