foldroid is a mail folder selection tool. For people who use mutt or a similar text mode mail reader, foldroid is a convenient tool to navigate through your mail folders. It shows how many messages are in each folder and how many of them are new. This, combined with a tool like procmail to sort mail messages of mailing lists into separate folders, makes selecting the right folder to read easy. Foldroid works best when you run it in a screen session, because it then starts every instance of mutt in its own screen.
ntdisp, short for NtD In System Programming, is a system for programming LPC and STM32 (and possibly other) embedded devices. It provides three different frontends, a GObject-based library (for developers), a commandline utility (for computer geeks), and a GTK+3 frontend (for less geeky users).
