Pettit and his colleague Paul Strefling, sitting in the pilot’s seat between us, are engineers in the business of ride quality. Their job is to program the movable parts on an airplane’s tail and wings—the rudder, elevators, and nearly two dozen ailerons, flaperons, and spoilers—to smooth out its flight automatically when turbulence hits. To get data for the simulator, their team takes full-size Boeing jets on research flights over the Rocky Mountains. They hunt for rough air, then loop through it again and again, like race-car drivers on a test track. They record every flutter and quake using the plane’s sensors, then download them to the simulator’s computers. The flight deck we were in could be swapped with one from a 737 or a 787, and the turbulence reprogrammed for the size and shape of those planes. Then, with the flip of a switch in the control room next door, the cab would start to shake and roll on its piston legs, as if having a seizure.

在一个供应链高度同质化的行业里,当「数字排毒」的新鲜感过去,护眼平板的市场日渐饱和,厂商们该如何拉出差异?
RE# started as a research project to combine multiple things - first we wanted to bring boolean operators back from the 1964 paper where they originated, then we wanted to extend the .NET NonBacktracking engine, which was, the way i see it, being held back by backwards compatibility (i.e., a safe drop-in replacement for the PCRE existing engine, which meant that it had to support the same features and semantics). we wanted to break free from those limitations and see how far we can push the new engine without worrying about compatibility.
