Welcome to my 1994-style homepage.
Various bits of open-source software I've created or contributed to over the years.
A Perl module for building nice OO command-line applications, with sub-commands, option processing,
and automatic generation of help text and man pages. Inspired by MooX::Options and MooX::Cmd
(which are themselves descendents of MooseX::Getopt and MooseX::App::Cmd), but unlike the above,
it's pure-Perl which allows it to be used in easily-distributed "fatpack" apps.
Yet another Perl IRC bot. Based on an old codebase called Sporksbot, but updated to be fully async
(using Net::Async::IRC, Mojo::Pg, Mojo::UserAgent, etc.) and with a few other bells and whistles.
Adds Unicode case folding via the fc operator to perls that lack it. The fc
operator is part of perl itself since version 5.16, but by using this module, it's made available
in any perl from version 5.8 onwards. Contains both pure-perl and XS versions.
An ionospheric propagation prediction tool for HF radio, combining the IRI2016 physics-based model
with realtime ionosonde data and Gaussian Process interpolation, employing a simple ray-tracing engine
to predict usable frequencies. As far as I know, it's the only assimilative model of its type that
is free and open-source. Hosted at prop.kc2g.com.
