Crash course in Dev for Ops? I schooled in CompSci where we were primarily taught Java, but what I learned there is that my passion is systems, so I've always worked the ops side. I'm handy with scripting, so I'm not looking for a site to teach me Ruby, but something to explain more in-depth what you devs do all day. I want to understand the culture better and how you digest the sheer number of files in your projects -- the intangibles. 

If I learned today I was being moved to a development team on Monday, what would I want to read this weekend?
Since you've tagged this question as "culture", I'm assuming you're not interested in a specific application, but in the broader questions of workflow and management.

I'd probably start with "The DevOps Handbook"; it's a good overview of different things to consider, without diving too deep.

"Continuous Delivery" by Jez Humble is also often referenced; I haven't read much of it yet, but it covers the concepts of source control &amp; automation of builds.

If you're starting to get into applications at scale (this may be too much of an assumption), another good book is "The Practice of Cloud System Administration" by Limoncelli et al.
