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.

Scala REPL (Read Eval Print Loop)

You can get into a REPL on (OS X or Linux) from your terminal, from two different commands.

If you have scala installed, you can type:

$ scala

Or, more likely, you have sbt installed:

I’m looking forward to the Sass Fundamentals workshop! A few notes to ensure you’re set up in advance are below.

See you soon!

Node.js

You’ll need a relatively recent version (v4.5 or newer, v7 ideally) of node.js installed. On OS X, a great way of doing this without disturbing your existing dev environment is to install NVM. Installation instructions are here.

Participants should have a recent version of Node.js installed on their system (preferably the latest LTS version, which is 6.9.1 as of this writing—but anything from 0.10 on should work). Participants should clone the following repositories and run npm install in each of them prior to the start of the workshop.

Optional: It might be helpful to install Electron globally so that you can use it from the command line in case there are any issues with any of the dependencies in the project above. You can install this through npm install -g electron.

Finally, debugging the main process is easiest using Visual Studio Code, which is available for all platforms (Windows, Linux, and macOS). This is not a hard requirement, but helpful if you'd like to follow along for that small segment of the workshop.

Building a desktop application with Electron

This is a tutorial for building a Markdown-to-HTML renderer using Electron. It is meant to accompany my session on Building a desktop application with Electron at JSConf Colombia.

The slides for the first part of the presentation are available here.

Create database

rake db:create

Create database table

This will creates a migration file in /db/migrate without table definition.

rails g migration create_<TABLE>

1. Clone your fork:

git clone git@github.com:YOUR-USERNAME/YOUR-FORKED-REPO.git

2. Add remote from original repository in your forked repository:

cd into/cloned/fork-repo
git remote add upstream git://github.com/ORIGINAL-DEV-USERNAME/REPO-YOU-FORKED-FROM.git
git fetch upstream
