With two busy teens, scheduling a family vacation can be tough. Rather than try for something longer right now we just went up to Nantahala Outdoor Center and Nantahala Village for the weekend. Fun time.
Not really a security post this time despite the title although I am waiting on a tool to do its job. Sometimes you just need to wait by doing something else.
Why do developers need secure development training as well as their regular training? The answer to that starts with a side trip into the aviation world.
Have you ever wondered why the windows on commercial airliners have rounded corners instead of square ones?
In the 1950s when jet service was fairly new there were a series of crashes of de Havilland DH 106 Comets, the first production commercial jetliner. During the investigations into the crashes it was discovered that the hulls experienced metal fatigue, something that was little understood at the time, and could fail catastrophically. As the cabin was pressurized and depressurized over and over and encountered repeated changes in temperature while changing altitude it cause metal fatigue that weakened the structure. In some areas of the structure there were special stress points that experienced more problems than others. One of these special stress points were the corners of the square cornered windows on the original versions of the Comet. The square corners caused levels of stress two to three times greater than the rest of the fuselage. The metal was going to fail after a number of flight cycles with one of the crashes coming from as few as 900 flights. Continue reading “Secure Development Training – Learning from Failure”
