Note: I used the wrong link initially when publishing this episode. If you are hearing the wrong conversation, delete the episode and re-download it. Thanks!

Jeaye has a background in C++ systems programming, focusing on games and game engines. After 5 years of that, he co-founded an esports tournament startup written in full-stack Clojure for another 5 years. These days, he’s at Electronic Arts (EA) building tooling used to make some of the world’s top games.

In each space, C++, Rust, Clojure, NixOS, etc, Jeaye aims to make an impact with his open source projects. For Clojure, at first, that was with Orchestra. Now, the flagship is jank.

Chris Nuernberger talks about his work on tvm-clj, unsigned bytes on the JVM, efficient copying of data, neural networks, GPUs

Chris has a wide background across many different areas of computer science and software engineering. He first got into GPGPU programming around 2008 with a research group at CU trying to auto-optimize a simple linear algebra expression (y = Ax + b). He first got into LISP with cmucl after a bout of RSI (pain in hands and fingers) convinced him that mainstream languages at the time (C++, python, C#, Java, ML) didn’t offer enough leverage for the types of projects that he was involved in. He is currently a partner at company named Tech Ascent based in Boulder, Colorado.
