Bidwell (named for Shelford Bidwell, the inventor of the first true fax machine way back in the late 1800s) is a set of Perl scripts that are designed to run as a cron job on a Unix-like system to download emails from a POP3 account and send their contents to a CUPS or lpr printer.
Mr.Java is a Java IDE that is one step above a command line interface, but not quite as confusing as an IDE. It will compile for you, add libraries to your class path, and run the whole thing, with three simple buttons. Drag a library or Java source file over the window, and it will be put in the right folder. When running programs, the stout is written to a file cleverly named “stdout”, and the std err is cleverly written to file named - you guessed - stderr.
