A simple command to convert calendar dates to julian dates. Quite useful in timing situations where you need elapsed time between dates. Also useful for astronomy applications.

Average is a simple and fast command-line Perl utility for calculating basic statistics on a list of numbers (one number per line). It works as a traditional Unix filter and can be used as part of those greatly useful chains of piped commands. It calculates average (arithmetic mean), standard deviation, median, total sum, minimum and maximum values present, and shows the number of processed numbers. Entry can by a text file (any column can be specified, default is the first) or directly in the terminal if Average is run without specifying a file -- in which case, input can be terminated by pressing Ctrl-D. It is possible to choose the output of a single statistic (just the value, no labels), instead of the fully detailed output (default).

DioXygene is a project of a new calculator using a motorola processor. It will have a multitasking operating system and a support of RPL, C and ASM language directly on calc.

This is mostly a pet project of mine. Using the rules for Eschaton set forth in David Foster Wallace's novel "Infinite Jest," I've been developing a program that can be used for a real, live game of Eschaton. It's still in the early stages, and I'm planning on adding more features. Still, the program is featured enough to be used for a real game.

This is a small cgi script, written in perl, which can generate character statistics for player characters in the online game Final Fantasy XI. This is a continuation of Japanese code released under the new BSD license.

Calculates alcohol content by weight and volume based on specific gravity readings. Also determines plato values, calories, refractive index and attenuation. If the values match a style of beer, or cider, it lists the style, and SRM for the style.

MaDiCal was developed to calculate the length of training runs or cycling tours. It loads map images in GIF format. The user first defines the map scale in one of several units and just clicks along the track. The length is calculated on the fly.

PerlCalc is a command line calculator designed for *nix systems. It is fitted with all the necessary geometric formulas and is divided into modules to make it easier to maintain. All in Perl under strict. Give me your feedback and make some patches
