Allan Blomquist demonstrates the internal programming and debugging tools Tomorrow Corporation uses to make games, including live modification of a running game and time-travel debugging.

Cliff Click of Azul Systems asks what a JVM is supposed to do, in a Google Tech Talk from 2011. He covers the services a JVM provides, such as garbage collection and compilation, and the messy reality beneath the abstractions.

An excerpt from the 1983 BBC series Fun to Imagine in which Richard Feynman describes how he and a mathematician friend counted in their heads in different ways, one verbally and one visually. It shows that people can reach the same goal through quite different mental methods.

Liz Rice builds a container from scratch in about 100 lines of Go, showing that a container is not a lightweight VM but a set of Linux kernel features and flags.

The first 3.5 hours of Tony Alicea's Udemy course on JavaScript's inner workings, covering topics such as first-class functions, closures, prototypal inheritance and how the language behaves under the hood.
