Planets is a fun, interactive program for many-body gravity simulations. The emphasis is on play: it's easy to add in planets, zoom in and out, change the physical constants, save and load configurations, etc. It's designed to be easy enough for a kid to enjoy, but that hardly precludes adults.
Orpie is a fullscreen RPN calculator for the console. Its operation is similar to that of modern HP calculators, but data entry has been optimized for efficiency on a PC keyboard. Features include extensive scientific calculator functionality, units support, base conversions, command completion, configurable keybindings, and a visible interactive stack.
Confluence is a functional programming language for reactive system design, including FPGAs, ASICs, and hard-real-time software. Confluence system descriptions have a large information to linecount ratio. It is typically two to five times more compact than Verilog. Confluence can compile a single body of source code into to Verilog, VHDL, C, and NuSMV.
MyCGR implements the research of the thesis of Peggy Cénac regarding the use of CGR (Chaos Game Representation) to build a new family of tests for the structure of sequences. It can empirically check the level and power of the tests and apply them on DNA sequences. It can generalize the dinucleotide abundance profile to a CGR-based relative abundance profile and use this profile on DNA sequences to build taxonomy trees and to define CGR-trees.
