"While I've developed programs for a variety of different operating systems, my favorite by far is Linux. I believe that Linux is the operating system of choice for autonomous vehicle manufacturers, including Tesla. This due to its economy and the large, open-source community of people and tools. I especially like working with Ubuntu since it works so well with autonomous vehicle development tools, and embedded Linux, a deterministic, Real-Time Operating System version of Linux. If you don't already have an Ubuntu machine, I can install a VM with Ubuntu."
