I think that one of the best ways to stay current with whatever tools, languages, etc. that you’re working with is to take a look and see what other communities are doing with their tools.
For what it’s worth, I also think that bringing experience from previous projects and/or jobs to new projects and/or jobs is important – you get a chance to continue doing all of the things that worked well, a chance to avoid the things that didn’t work, and a chance to discover a new set of things that work and things that don’t.
One of the more popular tools to come out as of late is Docker. There are a lot of really cool things about it, and there are a lot of articles already being written about it. I recently read one that struck a chord with me and with WordPress-related development.
Especially this quote:
Logging is a critical part of running an application. It’s often undercooked because it’s been here for so long no one think about it anymore. But trust me, when things stop logging, admins start crying.

Yes, it’s a good read for anyone who likes to see how other developers are doing their thing in another area of the industry and there’s a number of points made that I think many people who have been working in software for a number of years can identify with, but I couldn’t help but ask myself if I’m doing (or we’re doing) enough logging in the WordPress projects I’m (or we’re) deploying.
