#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.

Security inspections

At the beginning of each month, we carry out a brief, high-level security inspection. The purpose is to be a sanity check for head-slapping, trivial vulnerabilities that no one expected would be in the code but somehow managed to creep in anyway.

Who's responsible?

One of @alice, @bob or @charlie should do the inspection if no one else has the time.

How often?

Architectural Questions

• Are responsibilities well defined?
• Are the collaborations well defined?
• Is coupling minimized?
• Can you identify potential duplication?

Using better_errors on Ubuntu with SublimeText 2

After I installed the fantastic better_errors gem, I was disappointed to notice that linking to your text editor doesn't work correctly on Ubuntu (at least, it didn't for me). Here's how I fixed it.

First, create a new desktop entry:
