In the spirit of "It's fun to make lists", tell the forum what software you use in your field of study - with emphasis on what programs you use, rather than what general purpose computer languages you use. How much of your software is used because its a favorite of a particular department at a particular university ? Physicists and astronomers often make posts with acronyms designating programs I've never hear of - what are their full names? What do they do? Electrical engineers use programs to set up "programmable logic devices". Are there lots of programs of this type? Nothing much to report, myself - I'm retired and my only work is serving as executor of an estate - for which LibreOffice writer and calculator come in handy.
