I'm looking for readings, blogs, books, opinions about PMing software meant for developers/engineers

I was thinking about this excellent article called Product Management for the Enterprise by Blair Reeves.

Is there something like this for when your customers look a lot yourself? Or when they know what great software looks like? Or when they have strong opinions about features?

How is building software for engineers and software teams different to other customers? What are the nuances?

Thanks for any help/direction!
