add some notes on game dev
interval trees and some sources
fix vim tmp file on windows, diff sha style
no need for this post anymore & dilutes quality
switch to new AST traversal, toc metadata option
update pandoc to 1.12
serif & numbered headings, uniform font variables

The numbered headings are something of a hack. It requires gradual
increase/decrease of header usage, i.e. h1 > h2 > h3, not h1 > h3

Switch to serif headings, seems a bit nicer.

Uniform font variables, $font-serif, $font-default, $font-mono
switch tabs to spaces
bulk update to new toc metadata
publish algorithms, cpp, game-dev notes
perceptrons
