Tom Murphy (suckerpinch) shows 'reverse emulation', using a Raspberry Pi in an NES cartridge to give an unmodified NES new abilities such as playing SNES games. The video starts in a strange way and gets stranger.

Bobby Powers presents Mesh, a drop-in malloc replacement that eliminates memory fragmentation in unmodified C/C++ programs by compacting memory. The talk covers how it works despite C's fixed object addresses, and its benefits for programs like Redis.

David Sachs of InvenSense explains how gyroscopes, accelerometers and compasses work on their own and together, demonstrated on a modified Android handset. He covers sensor fusion algorithms and why rotation math such as Euler angles matters.

Emery Berger's CppCon 2019 talk introducing Mesh, a drop-in malloc replacement that compacts memory in unmodified C and C++ programs. It tackles fragmentation by merging pages without changing pointers.

Charlie Miller and Chris Valasek present their DEF CON 23 talk on remotely compromising an unmodified Jeep, pivoting from the entertainment system to the vehicle's internal networks to send control messages. They aim to show the reality of car hacking.
