Test post

This is a sample post to test the appearance and layout. This site is created using the static site generator Hugo

Here is a code block with syntax highlighting using Chroma

def fib(n):
    a, b = 0, 1
    while a < n:
        print(a, end = ' ')
        a, b = b, a+b
    print()

fib(1000)

Math is rendered using KaTeX. This is an inline expression: $\textcolor{#228B22}{e^{i \theta} = \cos \theta + i \sin \theta}$

And below is a display mode expression:

$$e^z = \lim_{n \to \infty} \left(1 + \frac{z}{n} \right)^n$$
