The problem

Cocalc exports notebooks to LaTeX using a default provided by nbconvert when File > PDF via LaTeX is clicked in the menu.

I wanted to be able to customize the default LaTeX settings (found at /ext/jupyter/nbconvert/templates/latex), however this contains read-only files on the system. So, I created a local config, but they do not automatically override the system settings. After interpreting the docs, I found how to override the system default.

The recipe

1. First, copy the folder /ext/jupyter/nbconvert/templates/latex to /home/user/.local/share/jupyter/nbconvert/templates/latex.

Overfitting happens in education; it's called specialization.
