the days before "open source" was defined.
- PIA (1999-2001)
on Github: ssavitzky/pia-server
- A web server and templating engine for HTML and XML, with
functional-programming semantics and XML syntax. It makes a
single pass through the input file, making it suitable for
low-memory applications. Ugly, but remarkably efficient.
Originally written in Perl, rewritten in Java, partially
rewritten to use the newly-defined DOM, and later ported to
C. Note that the earliest versions were roughly contemporary
with the development of PHP, and predated both XML and the DOM.
I designed the language and wrote the XML/HTML
parser, the interpreter, and the DOM library. This will also give
you a good idea of how I like to organize a project, with
HEADER.html files in most if not all directories. (These are
gradually being replaced with README.md as things get moved to
- These are the tools I use to manage multiple websites, songbooks,
recording projects, and so on. Also a
good example of how I organize projects and use Makefiles as a
way of aggregating commonly-used code snippets.
- Silvermine Resources products
- I wrote this suite of programs for my late father's now-defunct consulting company. They ran under
MS-DOS, and provide a simple
mc-like interface for
transferring and converting files written by a variety of
different Perkin-Elmer spectrophotometers and other devices. The
project involved writing drivers for several different
filesystems, and used
make for incremental backups
and production as well as compilation.
