In the spring of 2011, inside a cramped Stanford University dorm room, a 22-year-old Bobby Murphy sat at his laptop writing the code that would make digital messages…

Brad Cox co-created Objective-C by merging C with Smalltalk message passing, powering every Apple app for decades and pioneering the Software ICs concept of reusable software components.

In the world of software development, few tools inspire the kind of devotion — and the kind of jokes — that Vim does. “How do you exit Vim?”…

Most people who design software think about it in terms of tools — menus, buttons, inputs, outputs. Brenda Laurel looked at a computer screen and saw a stage.…
