About me

I am an experienced software developer, currently residing in Japan. Those interested may view my résumé (current as of 2019/6/9).

Software projects

Game software
I have worked on several ports of game software, including the iPad ports of the award-winning games Aquaria and FTL: Faster than Light. I have also developed a cross-platform toolkit, among other projects.
Gentoo Linux resources
Various resources and documents related to the Gentoo Linux operating system.
A recompiling translator for machine code (current version: 0.2, last updated 2019/10/10).
A robust and fast decoder library for Ogg Vorbis audio streams (current version: 1.16, released on 2023/7/14).
PlayStation 2 Linux files (Japanese only)
Various files useful for PS2 Linux development, including instructions on installing Linux alongside game data (English translation also provided) and a filesystem module for accessing the PS2's native filesystem format.
PSP game clock
A simple game clock for use in games like chess or Go to track each player's remaining time.
Services for IRC Networks
Services was one of my first major software development projects, developed and maintained over a period of 15 years. It was also one of the first open-source IRC service software packages, and it has spawned numerous derivatives adding different sets of features.

Other things

Console RPG information
Many years ago, I created a set of Final Fantasy 1 maps as an aid in playing that game.
Dragonfire Internet Services: A Retrospective
A retrospective on Dragonfire Internet Services, the web service provider I ran as a university student from late 1995 through early 1999.
The Parable of the Toaster
A view on system design principles.
Photo album
Pictures from various trips I've taken. (Only Japanese captions at present.)
Things Seen in Japan
I recently came into possession of a copy of this illustrated depiction of life in Japan by English writer Clive Holland, published in 1907. As the book's copyright has expired, I have published it on the web (click the link above) for your reading pleasure. The descriptions and photographs make for a fascinating contrast with modern-day Japan.
