how can i ssh into a server, and read a pid file and bring back the #?


Easiest way is with backticks.

Bring a UIView to the front for `UICollectionViewController`
You want to move the "View" aka "Progress View" outside of the collection view and below the photo browser in that hierarchy, which would cause it to be the front-most element in the view. The lower something is, the more forward it is. You can then also use autolayout ("Editor" -> "Align/Pin/Arrange/etc") to reposition or center your progress view.

BookshelfJs failing to bring in nested relationship on create
I'm not completely clear what you are trying to achieve, but here is how I would generally set things up. First I'd create a base model (assuming its saved as base.js), I think you are going to have some problems with circular dependencies, so using the Bookshelf registry plugin would be good: var config = { client: // whatever client you are using, connection: // url to your database }; var
