"Rappers" on the roof of the electrostatic precipitator knock the accumulated dust free, letting it fall into the storage hopper. Each rapper is the size and shape of a baseball bat. Inside is an electromagnet that pulls a steel plunger upward, then allows it to fall again, producing a sharp knock. The rappers are energized at seemingly random intervals, producing a haunting, syncopated music. (The rhythm seemed more modern jazz than rap.)
Today population forecasts are based on extensive and reliable data. However, no such demographic base exists for the world's growing population of machines and devices. Now may be the time to take machine demography seriously and enter into real discussions about machine population control.
The couple of years in question here saw one of the largest bureaucracies anywhere undergo a convulsion in which it tried to reconceive itself as a non- or even anti-bureaucracy, which at first might sound like nothing more than an amusing bit of bureaucratic folly. In fact, it was frightening; it was a little like watching an enormous machine come to consciousness and start trying to think and feel like a real human.
People mix the terms UI and UX together. UX is tricky because it doesn’t refer to any one thing. Interface design, visual styling, code performance, uptime, and feature set all contribute to the user’s “experience.” Books on UX further complicate matters by including research methods and development methodologies. All of this makes the field confusing for people who want to understand the fundamentals.
That’s why I avoid teaching the term ’UX.’ It means too many things to too many different people. Instead I focus on individual skills. Once you understand the individual skills, you can assemble them into a composite system without blurring them together. For software design, the core skill among all user-facing concerns is user interface design.
