Van Jacobson's 2006 Google Tech Talk argues that networking should be rethought around named data rather than host-to-host conversations. He contrasts the circuit and datagram views of the internet and sketches content-centric networking as a replacement for the location-centric TCP/IP model.

Van Jacobson's 2006 Google Tech Talk argues for rethinking networking around named data rather than host-to-host connections. He gives the history and the unsolved problems of the current internet architecture.

A short TV segment on Jill Price, a woman with highly superior autobiographical memory who recalls nearly every day of her life. She describes the good and bad sides of never forgetting.

A condensed film of Dick Proenneke's footage of building a cabin and living alone in the Alaskan wilderness, using hand tools and local materials. It draws on the 8mm films he shot himself.

A short Princeton CITP video describing cold boot attacks, where encryption keys remain in DRAM after power loss and can be recovered. It covers the attack against disk encryption such as BitLocker, FileVault and TrueCrypt.

Matthias Wandel shows his wooden machine that adds binary numbers using marbles. It demonstrates computation with purely mechanical logic.

A binaural audio demo, the 'Virtual Barber Shop', that places a barber moving around your head. It works best with headphones and closed eyes.

The first lecture of Stanford's CS107 Programming Paradigms, taught by Jerry Cain, giving an overview of the course. The course goes from C and assembly through C++, concurrency, Scheme and Python.

A Google Tech Talk by the author of Kilim, a Java library for lightweight actor-style message passing. It argues that message passing can replace shared-memory concurrency and claims performance competitive with or better than Erlang for huge numbers of actors.

Vim author Bram Moolenaar's 2007 Google Tech Talk on habits for efficient text editing: find inefficiencies in your own editing, then learn the Vim commands that fix them.

A demonstration of the 1982 Xerox Star user interface, including its desktop, icons, documents, networking and printing. The uploader argues that Apple's later Lisa and Mac interfaces evolved from these ideas rather than copying them.

Dan Bornstein's Google I/O 2008 talk on the internals of Dalvik, the virtual machine that runs Android code. It covers the motivation for its design, the dex format and its register-based interpreter, plus tips for writing code that suits the platform.

A roughly ten-minute demo of Microsoft's Intentional Programming research system, showing its editor and an unusual way of working with code. It is the first of two clips cut from a longer video.

Second half of a demonstration of the 1982 Xerox Star user interface. It shows how the Star differed from the later Lisa and Mac interfaces, with strengths in networking and printing and little direct manipulation.

A one-minute UK road safety advert showing a family car crash in which an unbelted rear passenger kills his mother in a head-on collision. It is a notoriously graphic public information film.
