Comparison of our core Rails app using Webrick, Puma, and Unicorn. Almost no effort was made to optimize either application server. Tests were performed on a MacBook Air using `siege` to hit the application homepage.

TL;DR

Unicorn was by far the best performing (5.94 trans/sec over the 1-minute test, 352 total). Puma (3.95 trans/sec, 235 total) appeared to perform no better than Webrick, despite the default behavior of using up to 16 threads. Perhaps increasing its worker count to the number of cores will improve its performance.

I've tried to run multiple Puma workers with the workers directive (per their sample documentaiton), but I receive errors about undefined method 'workers' for #<Puma::Configuration::DSL:0x007ffca4bde798>).

Signing your Git Commits using GPG on MacOS Sierra/High Sierra

Methods of Signing with GPG

There are now two ways to approach this:

  1. Using gpg and generating keys
  2. Using Kryptonite by krypt.co

This Gist explains how to do this using gpg in a step-by-step fashion. Kryptonite is actually wickedly easy to use-but you will still need to follow the instructions

For using a GUI-based GIT tool such as Tower or Github Desktop, follow the steps here for signing with either GPG or Krypt.co.

15 Questions to Ask During a Ruby Interview

Originally published in June 2008

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.
