When hiring Ruby on Rails programmers, knowing the right questions to ask during an interview was a real challenge for me at first. In 30 minutes or less, it's difficult to get a solid read on a candidate's skill set without looking at code they've previously written. And in the corporate/enterprise world, I often don't have access to their previous work.

To ensure we hired competent ruby developers at my last job, I created a list of 15 ruby questions -- a ruby measuring stick if you will -- to select the cream of the crop that walked through our doors.

What to expect

Candidates will typically give you a range of responses based on their experience and personality. So it's up to you to decide the correctness of their answer.

    desired_capabilities: {
      "chromeOptions" => {
        "args" => %w{ window-size=1024,768 }
      }
    }
  )

This allows you to access the development server of your app without starting rails server. This means you can access multiple development site at the same time. Useful if you have an API app and another app to work together with.

Setup

# install
curl get.pow.cx | sh

Install with Homebrew

brew install redis

Set up launchctl to auto start redis

$ ln -sfv /usr/local/opt/redis/*.plist ~/Library/LaunchAgents

/usr/local/opt/redis/ is a symlink to /usr/local/Cellar/redis/x.y.z (e.g., 2.8.7)

The easiest way to load the Mysql Time Zone tables from your Mac OS time zone fields is via this command:

mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root mysql

However, on many systems like mine that will fail because some of the time zone information is incompatible with the database schema for the time zone tables.

Therefore, you'll want to load the time zone information into a text file and edit it to only include the time zones you need. (Or, attempt to find the data breaking the import.)

mysql_tzinfo_to_sql /usr/share/zoneinfo > zone_import.sql

Wall Clock Time versus CPU Time

An important difference to note is the how time is reported by various measurement methods. Wall clock time is the actual time passed in terms of human perception whereas CPU time is the time spent processing the work. CPU time doesn't include any delays waiting on resources to free up such as thread interrupts or garbage collection.

The Work to Measure

To keep things simple, we'll create a Ruby Proc and just repeatedly call that Proc for each of the measurement methods below.
