Corner cases and documentationOne day, Lauren was playing with the MIT command module simulator’s display-and-keyboard unit, nicknamed the DSKY (dis-key). As she toyed with the keyboard, an error message popped up. Lauren had crashed the simulator by somehow launching a prelaunch program called P01 while the simulator was in midflight. There was no reason an astronaut would ever do this, but nonetheless, Hamilton wanted to add code to prevent the crash. That idea was overruled by NASA. “We had been told many times that astronauts would not make any mistakes,” she says. “They were trained to be perfect.” So instead, Hamilton created a program note—an add-on to the program’s documentation that would be available to NASA engineers and the astronauts: “Do not select P01 during flight,” it said. Hamilton wanted to add error-checking code to the Apollo system that would prevent this from messing up the systems. But that seemed excessive to her higher-ups. “Everyone said, ‘That would never happen,’” Hamilton remembers. But it did.
The mistake that led to the invention of CorningWareDr. Stookey had not planned to invent it. Experimenting at Corning one day in 1953, he put photosensitive glass into a furnace, intending to heat it to 600 degrees.“When I came back, the temperature gauge was stuck on 900 degrees, and I thought I had ruined the furnace,” he said in an interview several years ago. “When I opened the door to the furnace, I saw the glass was intact and had turned a milky white. I grabbed some tongs to get it out as fast as I could, but the glass slipped out of the tongs and fell to the floor. The thing bounced and didn’t break. It sounded like steel hitting the floor.”
For the preserving of that force we have to thank not the foresight of those recording companies but their ignorance and even philistinism when it came to black culture. They knew next to nothing about the music and even less about what new trends in it might appeal to consumers. Nowhere was this truer than at Paramount. These were businessmen, Northern and Midwestern, former salesmen. Their notions of what was a hit and what was not were a Magic Eight Ball. So, when the mid-1920s arrived, and Paramount went looking farther afield for new acts, they compensated by recording everything and waiting to see what sold. Not everything, but a lot. A long swath of everything. The result was an unprecedented, never-to-be-repeated, all-but-unconscious survey of America’s musical culture, a sonic X-ray of it, taken at a moment when the full kaleidoscopic variety of prerecording-era transracial forms hadn’t yet contracted. Hundreds of singers, more thousands of songs.
