Built on Authlogic they provide the views and controllers that Authlogic does not provide . Great for a drop-in authentication system . If you later need something more custom you can keep the Authlogic base and replace the controllers views with your own stuff .

  • Overloading Operators in Ruby

    Updated: 2012-01-31 21:39:18
    Ruby allows you to overload the arithmetic operators (as well as a few others).  This allows you define what a + b mean, even though a and b are types that you have defined.  This can lead to some very compact and expressive high-level code, as well as allowing you to implement some idiomatic Rubyisms (such as ...Read Full Post

  • Partitioning Strings

    Updated: 2012-01-26 14:11:18
    The 'split' method isn't the only fish in the sea.  The 'partition' method is similar, but doesn't consume the split string.

  • The Curious Case of the Flip-Flop Operator

    Updated: 2012-01-26 04:26:29
    The Flip-Flop operator is an odd thing.  It uses the range syntax, but doesn't produce a Range object.  Sometimes, it's true, sometimes it's false, but most of the time it's just confusion.  Should you be using it in your code?  That's up to you, but you really should know about the flip-flop operator, should you ever encounter it.

  • Ranges

    Updated: 2012-01-24 04:55:09
    Most languages don't have any concept of a "range."  To iterate over some numbers, you either define a minimum and maximum and iterate with a typical loop, or use a combination of comparison operators.  Ruby, on the other hand, has Ranges out of the box, and they can be used in a number of intuitive ways....Read Full Post

  • Using the Enumerable Module

    Updated: 2012-01-19 03:23:32
    Did you know that you can make any of your classes act like Ruby collections?  You can use any of the methods you'd typically use on collections (like Arrays and Hashes) on your classes by simply implementing the each method and including the Enumerable module.  Also, if the elements of your collection implement the spaceship () operator, your collection can even be sorted! Read more about using the enumerable module.

  • Why JRuby?

    Updated: 2012-01-13 21:45:24
    Java.  That single word is enough to turn many programmers away.  If you're one of those people (and even if you aren't), you should read on why you should be using JRuby.  It's perhaps not what you think it is, and certainly has its advantages.
