nMage is a (hopefully!) high performance 3D Game Engine written in Go being developed live, with recordings posted on YouTube.
This project is being built with the goals being (in no particular order):
Sharing knowledge about less popular/less taught (e.g. compared to web dev), yet very powerful computing topics by building things and explaining as we go
Showing the development process of large, high performance software, including things like: learning unfamiliar topics, reading docs, fixing bugs and profiling and optimizing
To build a good game engine that can actually be used to develop games
