From NASA to NASCAR: Space-Age Technology Finds Its Way into Auto Racing

Although it may not be obvious to the untrained eye, a number of technical innovations developed for aerospace and defense applications have found their way into the sport of auto racing. Take thermal barriers and driver “cool suits,” for example. Heat coming from the engine, transmission, exhaust system, oil coolers, etc., can cause temperatures inside the fully-enclosed cockpit of a modern stock car to reach 140- 160°F. Because of its close proximity to the exhaust headers, the metal floorboards beneath the gas pedal can heat up to 330°F or more — hot enough to fry an egg...or a driver’s foot.

Static vs. Dynamic Detection of Bugs in Safety-Critical Code

In the never-ending quest to produce high-quality software, traditional dynamic testing plays a fundamental role. The weakness of dynamic testing is that it is only as good as the test cases. To be effective, a great deal of effort must go into writing or generating good test cases, and doing so can be very expensive.
