Tips for Technical Writers

Here are slides from a lecture I gave on "Technical Writing: Tips for CS Students".

The SPoX In-lined Reference Monitoring System

SPoX (Security Policy XML) is a purely declarative policy specification language designed to be implemented by In-lined Reference Monitors (IRM's). Rather than performing security checks at an operating system level as is done with traditional Reference Monitors, an IRM modifies untrusted binaries directly so that they become self-monitoring. This allows policies to be enforced on untrusted code without modifying the operating system.

Our Java implementation of SPoX is still preliminary (early beta) but the in-development product can be downloaded below. We are currently in the process of creating useful literature such as a user manual, as well as a larger suite of sample policies to aid the non-expert user.

Derivation Trees

If you write papers about type systems in LaTeX, you may have noticed that it's unpleasantly difficult to typeset nice-looking typing derivations in LaTeX documents. The macros built into LaTeX or available in the amsmath package are designed for typesetting fractions, not derivation trees. One day I finally got tired of trying to make those work and wrote the following LaTeX package for typesetting derivation trees as they really should look.

Line-art Diagrams with Metapost

Metapost is an excellent tool for creating scientific pictures, just like LaTeX is an excellent tool for creating scientific documents. I wrote the following metapost package to make easy line-art pictures for importation into LaTeX documents.

Symbol Lists

While writing my thesis, I wanted to create good list of symbols, similar to LaTeX's built-in macros for creating lists of figures and lists of tables. I wrote the following package for the task:

Song Books

I originally taught myself the internals of LaTeX by writing a massive LaTeX package devoted to the creation of song books. The software I developed can function either as a stand-alone LaTeX package, or as a suite of utilities built atop the MiKTeX and Vim free software packages. The song books I created are currently being used by the Cornell Graduate Christian Fellowship and the Cornell International Christian Fellowship.
