 This sparked and interesting memory for me.  I was once working with a
 customer who was producing on-board software for a missile.  In my analysis
 of the code, I pointed out that they had a number of problems with storage
 leaks.  Imagine my surprise when the customers chief software engineer said
 "Of course it leaks".  He went on to point out that they had calculated the
 amount of memory the application would leak in the total possible flight time
 for the missile and then doubled that number.  They added this much
 additional memory to the hardware to "support" the leaks.  Since the missile
 will explode when it hits it's target or at the end of it's flight, the
 ultimate in garbage collection is performed without programmer intervention.

practice of defining tech through derision and scorn. "We excluded people. Directly. All of us. Even if we didn’t intend to, it does not matter. We make fun of the things others care about, make them feel small, make them feel like their achievements didn’t matter. Make them feel like they’re not welcome."
