John Lin reveals a rewritten voxel engine demonstrated in a Crystal Islands scene, with much finer voxel detail, fast collision, fracture and path-traced global illumination.

Glenn Vanderburg argues at the O'Reilly Software Architecture Conference that software development is an engineering discipline, even if immature. He contends the discredited body of knowledge called software engineering has led people to wrongly reject the label.

Hamish Coleman describes reverse engineering the keyboard controller in a Thinkpad and reflashing it with custom firmware. He covers how Lenovo secures its firmware, and his ongoing work on the protocol between the BIOS and the vendor flash tool.

A Linear engineer talks about scaling the company's sync engine, which keeps client data local and synchronized. It follows an earlier talk on the same system.

A GameTrailers walkthrough from E3 2012 of an Unreal Engine 4 real-time tech demo with Epic's Alan Willard. It shows live code changes and hot reloading while the game runs.

Hillel Wayne reports on interviews with 17 people who have worked as both software and traditional engineers. He argues the fields are fundamentally the same and have much to learn from each other.
