Other blogs about Ruby or Rails have already touched some of the tips I’m going to show, but it never hurts to remind you these small recipes aimed at Ruby novices:

My assignment this week, as senior Ruby on Rails developer for TrexGlobal (an US startup with some cool online apps for real estate investors that help you save lots of dollars on your taxes) was to add tests for some of the controllers in place.
Yes, I know, we should have used TDD(Test Driven Development) [...]

My cool colleagues from Trex Global gave me an unusual assignment this week: profile the current implementation of our first two apps, DeferEm and DepreciateEm.
Among the requests, the usual ones:

Request response duration
Execution profile of flow (path taken, time in methods)
SQL Queries made
Analyze and Identify performance bottlenecks – in-memory, sql query exec

Warning! This is not a full-blown tutorial, rather a quick step-by-step intro on what you have to do to run Rails on your Mac, if you are a noobie who just heard of Rails and wants to have it running on his computer ASAP:

Step 1 – Get Rails – Rumours say that in the [...]
