This is a simple site to demonstrate some concepts in Ruby on Rails and my coding style in general. The functionality is a listing submission site not unlike hacker news where people can submit links and then vote them up or down. It’s simple to use and incorporates some basic bootstrap styling and ajax techniqies for instant feedback.

Each user can submit as many links as they want. They can then vote up or down anyone elses link including their own although they are allowed only one vote per link. The user can change or cancel their votes at any time.

Future support will include:

• Commenting

• User profiles

• Changing and editing links

Some things to note:

1) The query to list all the links is done in a bit of a manual way. This is actually by design because I think its the most efficient way to get the information we need with a single query. The query returns a sum of the votes for each link as well as the current user’s vote for each link so we can display that in a meaningful way. I verified with miniprofiler that this brought improvements to the query time.

2) The ajax voting system gracefully degrades to html/post style voting in case the user is not using javascript.

3) I used bootstrap v. 3 for maximum mobile efficieny. Tests have been done to show Bootstraps flat design is much more suitable for underpowered mobile devices. The app is fully mobile tested.

4) Sign in is required to vote or submit posts, you’ll be redirected if not signed in.
