If you're writing web applications with Ruby there comes a time when you might need something a lot simpler, or even faster, than Ruby on Rails or the Sinatra micro-framework. Enter Rack.

Rack describes itself as follows:

Rack provides a minimal interface between webservers supporting Ruby and Ruby frameworks.

Before Rack came along Ruby web frameworks all implemented their own interfaces, which made it incredibly difficult to write web servers for them, or to share code between two different frameworks. Now almost all Ruby web frameworks implement Rack, including Rails and Sinatra, meaning that these applications can now behave in a similar fashion to one another.

At it's core Rack provides a great set of tools to allow you to build the most simple web application or interface you can. Rack applications can be written in a single line of code. But we're getting ahead of ourselves a bit.

Update: I no longer work for the company and this challenge is no longer used, but I'll leave the gist here in case people want to practice.

Alphasights Technical Challenge

Using Ruby on Rails we would like you to create a simple expert search tool. The application should fulfill the requirements below. The source code must be placed in a public repo on GitHub. The application should be deployable on Heroku.

• I enter a name and a personal website address and a member is created.
• When a member is created, all the heading (h1-h3) values are pulled in from the website to that members profile.
• The website url is shortened (e.g. using http://goo.gl)
• After the member has been added, I can define their friendships with other existing members. Friendships are bi-directional i.e. If Sasha is a friend of Ash, Ash is always a friend of Sasha as well.

Lambda: standard

# Creating a lambda
l = lambda { |name| "Hi #{name}!" }

# Executing the lambda
l.call("foo") # => Hi foo!

Cover Letter

My name is Ivo and I am an Italian agile software developer who loves coding and solving problems in a simple yet creative fashion. During my years of web development I have grown a strong passion for fronted development which led me to a good understanding of its underlaying technologies. I love hacking the hell out of web apps and getting a grasp of cutting edge technologies in order to keep up with time and deliver the best user experience possible.

While user experience still plays a big role in what I enjoy doing, I've learnt how important it is to write stable yet maintainable and scalable backend solutions. Even though I started out with PHP, I soon naturally came closer to the NodeJS environment while still embracing more "elegant" technologies such as Ruby or Java either adopting frameworks or by implementing architectures from scratch.

I discovered the Agile Manifesto and eXtreme Programming back while joining XPeppers in 2013 and I’ve tried my best to apply either values and prin

# You have your csv data and it looks like so... It's in a file named "my_data.csv" and we want to import it into a table named "my_things".

"1", "Something", "0.50", "2013-05-05 10:00:00"
"2", "Another thing", "1.50", "2013-06-05 10:30:00"

# Now you want to import it, go to the command line and type:
