Getting Hugo to work with Mathjax (or vice versa) to create these pages took a little bit of fiddling and some trial-and-error.

Everyone knows Euler’s famous identity, linking the imaginary unit to trigonometric functions: $$ \mathrm{e}^{\mathrm{i} \pi} = -1 $$ But another remarkable identity is also due to Euler, this one linking the set of prime numbers to an analytical function:

This article attempts to give an approachable introduction to the topic of database normalization and to the five Normal Forms.

Having managed to produce this site using the Hugo static site generator, it’s time to reflect and collect my impressions.
