C. R. Oldham

I am an experienced technologist currently working for SaltStack as Principal Engineer of the backend team for SaltStack Enterprise. While I have spent the bulk of my career in software architecture and engineering, team management, and DevOps, I did take a 6-year hiatus to start and run the Utah chapter of HopeKids.

I enjoy hiking, books, small-scale computing (microcontrollers like Arduino and ESP8266/ESP32, Raspberry Pi, Nerves), distributed and event-driven computing, as well as video games.

I work a lot in Python, run macOS and Linux, have been experimenting with Elixir, Erlang, and Go.

The domain name stands for a paraphrase (“Not conformed but transformed”) from a quote from the book of Romans: “And do not be conformed to this world, but be transformed by the renewing of your mind…”

Nickel the element is a transition metal. It is hard, but malleable and ductile when sufficient force is applied. It is resistant to corrosion, conducts electricity, and is not very reactive.
