The design of the selfie compiler is inspired by the Oberon compiler of Professor Niklaus Wirth from ETH Zurich. RISC-U, the target language of the selfie compiler, is inspired by the RISC-V community around Professor David Patterson from UC Berkeley. The selfie garbage collector is inspired by the conservative garbage collector of Hans Boehm. The design of the selfie microkernel is inspired by microkernels of Professor Jochen Liedtke from University of Karlsruhe.
That's quite the pedigree! This is a very interesting project to dig into, starting with the book.
