Canada, 2005, fresh off the boat immigrant, just graduated high school in Europe. I had already bought the open source idea years prior and used mostly open source software on Windows. Having recently switched to NVIDIA from ATi, I tested DotA 5.x (Warcraft 3 TFT) on Ubuntu via Wine. It worked great and that was the final hurdle to a full migration. Wiped Windows and installed Ubuntu. I've been using Ubuntu as the primary OS on all my computers ever since. I went through university with a Dell laptop, intentionally purchased to be compatible with Ubuntu. No NDISwrapper shit. The knowledge acquired over this period naturally flowed into my professional career where I've primarily used Ubuntu and RHEL for various use cases. From software development to software deployment and cloud operation in production. These skills keep helping my day to day work in automotive these days.
