All of my old Windows workstations and laptops inherited from work get Linux installed on them, then I do virtual machines and containers from there. 

With .NET Core running on Linux, it's easier to port tools and utilities to and from Windows and Linux. Along with other cross platform tools and languages, it's a good time to be a developer. 

I'm still working on replacing some low level hobby project drivers and such that are written in C/C++ with Ada. We shouldn't be dealing with C/C++ buffer overflows and the related security issues in this current year.
