What it is

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.

Why Hacker News recommends it

A repeated recommendation for anyone interested in VMs, with Click's talks regarded as unusually informative on JVMs, JITs and the user/kernel boundary.
