Beware of bugs in the above code; I have only proved it correct, not tried it.

Donald E. Knuth

Here is a list of the codes I wrote for my convenience. I put all of them on github. Feel free to use them if you need.

sorting network: a LaTeX program that draws sorting networks similar to the CLRS book.

everTex: a Chrome extension that shows formulas in EverNote’s web interface. It uses MathJax to do the display, so all formulas to be rendered should be written in LaTeX syntax, surrounded  by $$…$$, $…$, or $$…$$.
