My site offers a number of programs created in the course of my work in the history of medieval and oriental astronomy.

    The main programs are
Kairos
    general calendar conversion program.
Deviations
    graphical and numerical analysis of the parameters of historical astronomical canons
StarList
  listing of star coordinates based on the Bright Star List, with
 

Fontlist 5 and Fontlist 6 were developed in order to make it easier to handle a variety of fonts when using MS Word, amd now Word 2007.
Both are fully unicode compliant, listing the fontname in appropriate CJK characters. It will open any file, even when the filename consists of non-ascii characters.

Hanfind is designed to exploit the database UniHan.txt provided by Unicode. Hanfind provides, among other features, a list (sorted by tones) of all the Chinese characters for a given Pinyin reading.

Unicode Search is for those people who have hundreds of fonts on the disk, and need to know which will cover a given set of Unicode blocks. For example if you need to type Classical Greek, you need the blocks "Greek" and "Greek extended". If you want to transcribe oriental languages, you need besides the usual Latin blocks, also "Latin extended Additional". Do you really know which fonts you have for that ? Unicode Search has the answer !
