Engye – transfer files between any two devices by scanning a QR code▲15
Early in April I needed to print some tax forms at the library, first time in forever, and I began to wonder: what's the easiest way to get a file onto a public computer?

Last year, with all the talk about "AI replacing programmers," I got curious. As a developer with no…
