>I've seen your stuff in r/DIY and it looks like your main interest (outside of your work as an RoR dev) is hardware. Do you code for fun or do anything on the software side as well?

No, software is just to mostly just to support myself. I know there's a push for being passionate, but sometimes the thing we love about our work is just that it lets us do the things we love. Also internet issues in China make coding even with a VPN not so fun. I'd like to be able to just do hardware projects if I could.
