FCFS RWLock is a first-come first-served readers/writers lock for POSIX threads. FCFS means that the first thread to request control of the lock will gain it, based on the constraints of a readers/writers lock. FCFS RWLock is well documented and commented, so it can easily be used as a reference implementation.
Install Kernel (ik) is a bash script that installs the Linux kernel and automatically sets up LILO or GRUB. It also saves your kernel configuration each time you do an install. This allows you to restore the newest configuration file when you make a new kernel. This script is intended for two groups of people; people new to compiling kernels, and people who are tired of moving files around and editing their bootloader configurations every time they install a new kernel.
arrayfrombuffer allows a programmer to use Numerical Python arrays whose contents are stored in buffer objects, including memory-mapped files. Loading an array from a file is easy, requiring only a module import and a single function call. Loading the array is quick because it doesn't require any copying from one part of memory to another. Arrays created with arrayfrombuffer are also highly memory-efficient, since only the array data that you are currently using gets loaded into memory. When an array is modified, only the modified parts get written back out to disk. These arrays can also be bigger than physical memory.
