The firing squad synchronization problem

December 2001 BIGNUM BAKEOFF contest: rules, rules clarification (I), rules clarification (II), results. Comments by Heiner Marxen on his entry and a tar file containing commentary by Ralph Loader on his entry.

SimCity 2000 for MS-DOS file format; unofficial partial information

Bouwkamp codes of all simple perfect squared rectangles of orders from 9 to 16, and Bouwkamp codes of all perfect squared squares of orders from 21 to 24 (and some of orders from 25 to 27.) A brief explanation of the Bouwkamp code and squared rectangles is here. Also, the program I used to produce the squared rectangles is available as a shar file (66K), a compressed tar file (18K), or a zip file (19K). It is distributed under the GNU GPL.

Programs

astroutils

astroutils consists of two filters, astro2csv and csv2astro. astro2csv transforms astronomical data files from CDS format to CSV format; csv2astro does the reverse. astroutils is available as a compressed tar file (13K) and is distributed under the GPL. The current version of astroutils is 0.01.

bfdb

bfdb is an optimizing interpreter, debugger and compiler for the BF programming language. bfdb has the following features:

bfdb is available as a compressed tar file (72K) and is distributed under the GPL. The current version of bfdb is 0.03.

dumpisofs

dumpisofs is a utility which checks ISO 9660 filesystems for consistency, prints their headers, and prints their directory trees.

dumpisofs is available as a compressed tar file (28K) and is distributed under the GPL. The current version of dumpisofs is 0.001.

globe

globe constructs a three-dimensional model of a globe, which can be given relief or color on its surface as specified by input altitude or color maps. The model can also be made hollow or cut into pieces. globe is distributed with the program e2g2e, which changes the vertical reference of an altitude map from the WGS84 ellipsoid to the EGM96 geoid, or vice-versa.

globe is available as a compressed tar file (1.75M) and is distributed under the GPL. The current version of globe is 0.01. Also available are collections of altitude and color maps for the Earth (78M), Mars (63M), and the Moon (62M) for use with globe.
