What made your test runner faster? We would be very interested in porting those optimizations to ex_unit.

Elixir hasn’t done away with behaviours. They exist in the language and are used to implement features in the standard library itself and many libraries in the ecosystem. You don’t have to go to Erlang documentation to learn about them sinc

Yes, memory bandwidth is one of the biggest slow downs of ray tracing. Rasterization access memory very linearly which makes it very easy to cache and easy to optimize in hardware on the GPUs. But ray tracing access memory very randomly, tw

Yes. But the "constant factor" will be very large, even larger than for traditional ray tracing, for some global illumination algorithms, even when you chose to only render a small part of the scene. For example photon mapping requires a pr

Purity has nothing to do with green threads. Many languages that doesn't have the concept of purity have green threads, like Erlang or Go. In fact, green threads are not a part of Haskell, but a part of the runtime. Purity is just a nice th
