Facter is a cross-platform Ruby library for retrieving facts from operating systems. It supports multiple resolution mechanisms, any of which can be restricted to working only on certain operating systems or environments. Facter is especially useful for retrieving things like operating system names, IP addresses, MAC addresses, and SSH keys. It is easy to extend Facter to include your own custom facts or to include additional mechanisms for retrieving facts.

With the inherent support for SMP and preemptive scheduling in Linux, concurrency is a critical factor which has to be considered while designing kernel modules or device drivers. Avoiding race conditions can be a difficult task. Linux, as in any other OS, provides many synchronization primitives to manage concurrency. Semaphores and Mutexes are part of them.
