ECMA-55 Minimal BASIC is a compiler for "Minimal BASIC" as specified by the ECMA-55 standard. The target is AMD64/EM64T/x86-64 machines running a modern Linux distribution (a 3.x kernel). This compiler will create Assembly Language output files. These must be assembled into object files and linked to create an executable. The Assembly dialect used is that of GNU gas.
YASP is a simple and open protocol for building networks with small microcontrollers. It is designed to have a small footprint for easy implementation with minimal hardware resources, but without sacrifice advanced features and future growth. The protocol scalability is implemented using variable length fields. The physical layer use the NRZ encoding as in RS-232, but using dominant and recessive bus states to provide a reliable way to detect collisions.
GeekOS is a tiny operating system kernel for x86 PCs. Its goal is to be simple enough for beginners to understand and modify, but realistic enough to be interesting and fun. The primary development environment for GeekOS is Linux or Windows using gcc, nasm, and the Bochs PC emulator.
rtldi is an ELF program interpreter that makes it possible for executables to use their own ld-linux.so.2 and libc.so.6 and associated shared libraries, independent of the default versions installed in /lib and any other executable. It facilitates the simultaneous interoperation of programs that were originally linked using different generations of glibc6. In theory it should not be necessary, but in practice glibc6 has not always been backward compatible.
