elfsternberg / truetype.latex
Created Apr 17, 2020
Modified Pandoc default.latex template, now with Truetype and Opentype support.
View truetype.latex
% This is the default.latex file from Pandoc with a single change: I
% have added the fontspec, xunicode, and xltxtra packages to the
% fontenc invocation. This change allows you to use your Truetype and
% Opentype fonts with pandoc and make your markdown even prettier than
% ever. Example usage:
% pandoc --pdf-engine=xelatex --template=truetype.latex -V mainfont="Centaur MT Std" -o recipe.pdf

Uncle Bob's "Principles of Programming" lecture, reduced to a small SQL file with examples.
View uncle_bob_1.sql
Microsoft elder Robert Martin, aka "Uncle Bob," has a long series of
videos where he lectures on the joys and benefits of object oriented
programming. One thing he likes to say over and over is that your
data should not be tied up by the choice of representation, and that
the most problematic of all data representations is the choice of a
database far too early in the development process.
In his presentation on the Single Responsibility Principle (which I
