Note that this validation runs both after the file is uploaded and after CarrierWave has processed the image. If your base uploader includes a filter to resize the image then the validation will be run against the resized image, not the original one that was uploaded. If this causes a problem for you, then you should avoid using a resizing filter on the base uploader and put any specific size requirements in a version instead.

So instead of this:

require 'carrierwave/processing/mini_magick'

# SSL self signed localhost for rails start to finish, no red warnings. 

# 1) Create your private key (any password will do, we remove it below)

$ openssl genrsa -des3 -out server.orig.key 2048


# 2) Remove the password

$ openssl rsa -in server.orig.key -out server.key

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.

There are many (old) clients available:

• https://github.com/tpitale/legato (active, supports API v3)
• https://github.com/activenetwork/gattica
• https://github.com/vigetlabs/garb

The Google Analytics API is at v3 (at time of writing).

This example uses Google's Ruby API client to access Analytics. Use https://github.com/google/google-api-ruby-client (Google supported).
