#Ruby Interview Questions

What are blocks for?

Plain old english: Ways of grouping code we want to run. The simplest explanation for a block is that it is a chunk of code between {} or do...end, that can't be stored in a variable and isn't an object. A block is just part of the syntax of a method call. It doesn’t mean anything on a standalone basis and can only appear in argument lists.

What are the difference between p and puts?

The difference is subtle, but p prints the true value of an object, rather than a string-ified version of the object. This will make more sense soon, but for the sake of simplicity, we'll use the p command throughout the exercises, as we'll want to see the true values of our code returned to the output window.

Ubuntu 12.04 Ruby on Rails Development Environment

I haven't set up an install guide for the latest ubuntu release, largely because the last set of instructions worked pretty closely with the latest and greatest Ubuntu, 12.04 Precise Pangolin, however when installing today, I found that there were enough differences in the way that I configure my setup to justify an update, so here it goes. Yes, I'm late to the party, but a quick google search didn't find anything that I felt was as complete for my requirements as my previous install guides, so here I go.

As always with my install guides, I have included here is just about everything you'll need (and then some) to get started with ruby on rails development with Ubuntu 12.04 as a platform. These are my settings and preferences, and this is certainly not the only way of doing things, so keep that in mind.

Step 1: Get the repos ready and run updates.

sudo apt-get update && sudo apt-get upgrade
