boost last week, when aircraft engine builder Pratt & Whitney
revealed that it used a Linux-based software kernel to test its new

engineers said Linux, long considered ill-suited to real-time
applications, played a key role in highly deterministic, real-time
tests. They said that a Linux-based product known as RTLinuxPro
