SYINF shows in brief a system's CPU brand and model, RAM size, disk space, operating system, regional parameters, and current date and time. It can run in interactive (menu) or batch mode. There are two versions, in the C and C++ languages. They have been tested on 20 (15) compilers, 26 (25) operating systems, and 18 architectures. (Figures in parentheses are for the C++ version.) Both versions are conveyed in source code form only, each as a single ~35 KB source text file.
iBodyFat calculates your body fat percentage and keeps a log of your results. Two different calculations are presented for each measurement made. The body fat percentage formulas used by iBodyFat are the girth body fat calculations invented by the U.S. Navy and professional body builder and writer Hugo Rivera. For taking girth body fat measurements, no special equipment is needed. All that is required is a vinyl tape measure.
SHTns is a high-performance Spherical Harmonic Transform library. It was designed for numerical simulation (fluid flows, mhd, etc.) in spherical geometries, but can be used for any kind of problem involving scalar or vector spherical harmonics. It is very fast, thanks to careful vectorization and runtime tuning. It supports multi-threaded transforms via OpenMP. It features scalar and vector transforms, synthesis and analysis, and flexible truncation and normalization. A Python interface is included.
headstak is a stack-based task list. Before you start a task, or when you are interrupted while working on a task, you push the current job onto a stack. When the interruption finishes, or when the task is complete, you pop it from the stack - leaving you facing the job you were working on beforehand at the top of the stack. Run it and it should appear on your status bar as a little stack of stuff on a head. It is activated with the Control-Command-0 global hotkey.
Cube Trains is a puzzle game where you build elevated railways in a city. It features 3D puzzles, unlimited undo/redo, and smart placement of pieces. The non-linear level graph means you don't have to beat a level before unlocking the next one. The game comes with a built-in level editor, so you can build and share your own corners of the city.
