Harvey OS, Bringing Plan9 to the Earth

Harvey is an effort to get the Plan 9 code working with gcc and clang. According to the team: “Our aim is to provide a modern, distributed, 64 bit operating system that does away with Unix’s wrinkles and allows for new ways of working. At this point we have an AMD 64 bit kernel with many changes and improvements. For example, a new modern, simplified syscall system. We use gdb to investigate problems and we can compile in Linux or OSX using Harvey’s headers and libs; no need to change anything else. It’s fast compiling the whole system and boots quickly. Though we are working in many other features, all Plan 9 traditional userland is available. At this moment, we are working to move console and mouse out of kernel, ttyfs file server in user space, and improved ANSI/POSIX environment where gcc or clang can live, and we plan to add X11 with rio-like multiplexing, bash and other shells and many other well known things that people want in their machines. We are focusing in server set up for now, but keeping in mind end-user. All of this, of course, keeping classic and beautiful distributed features of old Plan 9.”
