alt Hacker NewsThis is really great resource, didn't know about it. But one question not related to the website above - why the syscalls vary per architecture if the linux API is the same?
Or is it I am confusing it with the C standard library/POSIX and assuming that it should be the same everywhere?
The Linux kernel API is the same everywhere, but the syscall ABI (numbers, calling convention, entry paths) is specific to a architecture, while it's the C library that wraps those details into the portable POSIX API we code against
