I think that there's good advice in this article, but a couple counter-points:
- Plenty of software developers work for small- to mid-size companies where the Node or Rails server running on your machine is nearly identical to the one running in production.
- Plenty of software developers work exclusively on the front-end, which means that the computer your code runs on in production is very very similar to the one you develop on (although then you have the added concern of testing on lower-end mobile devices, other browsers, etc)
