Here is a note for people who still write their own software. If there are any.
I use homemade software to keep track of the files at LENR-CANR.org, and to convert the EndNote files into the on-line php SQL database format. I was running out of filenames for Jean-Paul's JCMNS journal. I went to make a small change to the program to fix that problem and I discovered the compiler no longer works with the latest version of Windows 10. Yikes. The last time I checked, the vendor for the compiler charged thousands of dollars for an update. It turns out they now have versions of the compilers for free! These are immensely powerful by my standards, with features galore. See: https://www.embarcadero.com/free-tools They have two versions: Pascal (which they call "Delphi"), and C++ (which I call "unstructured"). The latest compiler is such fun I wrote a program to solve Sudoku puzzles. I do not have the patience to solve them by hand. It is fun to watch the computer solve them. I thought I could do it by iterating three procedures but it turns out it takes four. - Jed
