I have a request for hacker news, in remembering Tom Lord: do you have any of his code lying around? It's hard to find. In addition to GNU arch, I know he once worked on these things:

* a c library called hackerlab

* a Scheme implementation called Pika Scheme

* a regular expression library called rx (may have been renamed to rgx)

* an embeddable VM called Furth

* a graph reduction engine/functional language runtime of some sort

http://web.archive.org/web/*/http://regexps.srparish.net/src... has a few versions of hackerlab and pika.

hackerlab is also part of tla distributions (since the latter uses the former extensively)

hackerlab contains (some version of) rx.

A few of those links lead to actual tarballs, but sadly, the pika one does not. :(
