goal: how to build an awesome CI for your organization.  

Couple of years ago I was webdeveloper at Groupon working on a monlithic RoR webapp. 
We had grown rapidly and the webapp saw incredible amount of work put in. This also bought in lots of cucumber  tests and our build time shot up to 40 mintues. 

My Name is Surya Gaddipati, This is my story of my epic journey to build an awesome CI at groupon. 

CI is often setup as afterthought 
  > Teams consider it unimportant in grand scale of things
  > Teams often don't have the experience, interest

The problem was to find the unique assignment of the ten decimal digits to letters that makes this addition correct:

DONALD + KNUTH = OUTPUT

I like the cleanliness of it, but I'd like some more lines to identify different sections.
It feels a bit too floaty and not enough anchor.
and some border lines would help ground certain sections.

The header is a good example of being anchored, but the rest of the widgets feel unorganized because there's no barrier between them.

Seperate out branch/tab logic from dynamicproject. It doesnt belong there.

use permissions for configure button + add delete project option

include progress bar

ajax query should only return completed
