Dodoid gives an in-depth look at an SGI Onyx RealityEngine2, a $250,000 graphics supercomputer from 1993, covering its history, a physical overview, a teardown and some demos and games.

A short unscripted demo of writing FizzBuzz in JavaScript with a generator function on a steno keyboard, typos included. It gives a feel for what real coding in stenography looks like.

A short demo reel of the 1985 Silicon Graphics IRIS 2400 workstation animating flat-shaded polygons on a 68010 CPU. It shows the early SGI graphics that preceded their later fame.

A SIGGRAPH demo from Yoichi Ochiai's group of aerial and volumetric graphics drawn by focused femtosecond lasers with computational holography. The plasma points can be touched.

A brief toast by lithography expert Chris Mack at SPIE Advanced Lithography 2014, humorously declaring the end of Moore's Law. His argument centers on the cost per transistor no longer falling.

Christof Paar's university lecture introducing Galois fields and finite-field arithmetic as used in AES. It covers the mathematics behind the AES S-box.

A short National Geographic piece showing a laser system that tracks and kills mosquitoes, filmed in slow motion, as part of anti-malaria efforts. It comes from Intellectual Ventures' 2010 work.
