WARNING: None of this software is packaged for
release. Don't bother fetching it unless you like reading and
fixing other people's code.
I've discovered that if I put off making a piece of software
available for download until I've created a package that's in a
state in which someone could fetch it and use it without reading
and modifying the source, then I'll be putting it off forever. So
I put it here in the hope that (a) it will be useful to those who
understand it, and (b) that someone might volunteer to help me
create a more generally useful package. Most of it is in Perl and
requires Perl 5. Most of it is left uncompressed - it's easier to
view online that way, and it's so small it's hardly worth the
With the above warning in mind, please feel free to mail me with any
questions or problems with any of this software.
Well, substantial enough to have their own Web page,
- Several implementations of two strategies for turning biased
random data (eg from a Geiger counter) into fair random
- A Perl script for making photo
galleries like these.
- I've been playing with Lego Mindstorms, and made a Lego line
follower that goes faster than the normal one with some
- A Perl script that makes maintaining a remote website of
static pages vastly more convenient. No longer under active
development - I use rsync now.
- dials your ISP and runs a bunch of services when you
connect, drops the connection when it goes idle. Logs things. It
used to be setuid on my system before I got cable internet.
- the configuration file I use for ppp-connect on my
- if you get your mail through a smarthost, you can't use the
RBL directly - this script parses "Received" headers and allows
you to use the RBL at one remove.
- the beginnings of an SPKI toolkit in Perl. Currently this
has only one module, for fiddling with S-expressions.
- the Ciphersaber
cryptosystem in four lines of pure Perl.
- an implementation of Shamir and van Someren's algorithm for
finding high entropy stretches of binary files, described in
Playing hide and seek with stored keys.
- I once wanted to use bash in an environment that only set up
the csh environment properly, so this was my solution: this
script runs csh to find out what environment variables it set
up, then emits sh directives to do the same work.
- a teensy calculator for X video mode timings.
