An experimental debugging tool written in Java which allows "rewinding" and seeing what the values of variables were in the past. Works by modifying bytecode. [Freeware]
A command-line utility for reporting the differences between ASCII or binary files, or recursively finding the differences between two directories. [Freeware]
Pure functional language based on function composition rather than application; concatenative language, very like Forth, inputs and outputs stacks, but with higher-level data types and sound mathematical foundation. [Open Source, BSD]
Produces compile-time diagnostics of Fortran code using the Lahey/Fujitsu Fortran 95, Lahey Fortran 90, or Essential Lahey Fortran 90 compilers. Can show warnings, perform a Fortran 90/95 conformance check, warn about use of obsolescent features, forc...
Fortran 90 and 77 codes by W.H. Press and G.B. Rybicki, for fast inversion matrices of an exponential form arising from autocorrelation functions of Ornstein-Uhlenbeck processes.
Has programs from Gaspani for spectral analysis, GENSYS for general synthesis of light curves and line profiles for close binary systems, WINK for eclipsing binary curve prediction, and WUMA for generating line-broadening profiles.
Computational physics development environment written in Fortran 90. It provides an environment where the physics of real systems can be modeled, by discretizing a set of partial differential equations on a mesh and solving the resultant algebraic system.
