Miguel Hernandez, the founder of a company specializing in explanatory videos for startups, said he spent about three hours a day for three weeks making an online video course explaining his craft. But, last year, that one video series earned him nearly six figures on the online course platform Udemy. This year, now that he’s created a second course for students (on “How to Create an Awesome Online Course,” of course), he said that if momentum keeps up, “I’ll be making more money selling online courses than through the studio.”

And he’s not the only one finding a new stream of income from Udemy. This morning, the San Fransciso-based startup released the salaries of the top 10 instructors on the 2-year-old platform. In total, the group earned $1.65 million in the last year, with all of them bringing in more than $50,000 on their own and the top individual making more than $200,000. All of the instructors’ top courses focus on Web development, programming and tech entrepreneurship – not a surprise given Udemy’s roots in those field and increasing interest in coding.

The Gowalla development team has released Likeable, a Ruby library to make it simple to add social ‘likes’ to your Ruby classes.

With just a few lines of Ruby, you can track likes using Redis as your data store:

class Comment
  include Likeable

  # ...
end

class User
  include Likeable::UserMethods

  # ...
end

comment = Comment.find(15)
comment.like_count                  # => 0
current_user.like!(comment)         # => #<Likeable::Like ... >
comment.like_count                  # => 1
comment.likes                       # => [#<Likeable::Like ... >]
comment.likes.last.user             # => #<User ... >
comment.likes.last.created_at       # => Wed Jul 27 19:34:32 -0500 2011
