Exercise: Calculating the array mode: Write a method "mode" which takes an Array of numbers as its input and returns an Array of the most frequent values. If there's only one most-frequent value, it returns a single-element Array. For example, mode([1,2,3,3]) # => [3]
mode([4.5, 0, 0]) # => [0]
mode([1.5, -1, 1, 1.5]) # => [1.5]
mode([1,1,2,2]) …

Ideas are cheap. Make a prototype, sketch a CLI session, draw a wireframe. Discuss around concrete examples, not hand-waving abstractions. Don't say you did something, provide a URL that proves it.
Nothing is real until it's being used by a real user. This doesn't mean you make a prototype in the morning and blog about it in the evening. It means you find one person you believe your product will help and try to get them to use it.

Support for PostgreSQL `interval` type in Rails 4. Although ActiveRecord supports `interval` by default, it turns it into a string (and tells Postgres the column is type string, too). This means you don't get any proper interval goodness. By sticking this code into an initialiser, ActiveRecord will create proper `interval` column types in Postgr…
