I am retired from a commercial software company. I worked on custom integrations built with a variety of languages. My current interest is HDF5 with PyTables and/or h5py (which also involves Python and NumPy). My first programming language was FORTRAN (initially WATFIV, then FORTRAN 77). Over the years I've worked with C/C++, Unix and Windoze shell scripting, and some proprietary languages (for custom APIs). What a long, strange trip it's been!
