In the kernel:
1. Access to hardware performance counters and energy counters
2. Easily loadable custom drivers
3. File system that is not slow as hell ("Getting the modification time of a file ... seems to be about 100 times slower on Windows than it is on Linux"[1])
4. Practical mechanism to allocate large pages
5. Futex
In the ecosystem:
1. Package manager
2. C99 compiler
3. POSIX environment (a lot of scientific libraries and tools depend on it)
