density

Chris Celio of UC Berkeley compares the RISC-V, ARM and x86 instruction sets, with quantitative data on instruction counts and code density. It examines how the compressed extension fares against Thumb and x86.

David MacKay's TEDxWarwick talk uses basic arithmetic to show how much land and energy renewables would need to power a country like the UK. It explains the limits of sustainable options and why they should still be pursued.

Jim Keller gives a UC Berkeley EECS colloquium arguing that Moore's Law is not dead. He surveys upcoming technologies and the multiple innovation curves that can keep transistor density and performance scaling.

Michael Abrash of Valve explains what affordable VR hardware will be capable of within a couple of years, and describes a prototype showing what that level of hardware can do.
