Selfie: tiny self-compiling C compiler, MIPS emulator and MIPS hypervisor
This is a really, really cool project. Some fun quotes:<p>> In fact, selfie goes one step further by implementing microkernel functionality as part of the emulator and a hypervisor that can run as part of the emulator, on top of the emulator, and even on top of itself, all with the same code.<p>> The design of the compiler is inspired by the Oberon compiler of Professor Niklaus Wirth from ETH Zurich. The design of the selfie microkernel is inspired by microkernels of Professor Jochen Liedtke from University of Karlsruhe.<p>As someone who is vaguely trying to learn more about / get involved in kernel development, the easiest place to start figuring things out is in simpler kernels like this or Minix. (Then followed by OpenBSD. Then later on NetBSD / FreeBSD. Then much, much further, Linux. [Haven't spent time looking into Illumos yet but it's on the list.]) But I haven't actually been able to contribute much more than ports to any of these yet.
