A community about writing your own operating system; this includes projects like bootloaders, kernels, as well as some userland related topics like login- and display managers.
best community ever btw, i once wanted to create this operating system called GULA-GUG Basilisk, never got to it fully but i wrote/designed the "terminal" haha. Though i really love that terminal and its functions i still can't really live without it and use it everyday on my mac…
