The Amazing FunctionMap!
FunctionMap is a handy class that allows a set of object transformations to be mapped at run time without having to define a bunch of extra interfaces and without having to evaluate the transformations at the time the mapping is created. Suppose we have an object: class NumberPair { double a; double b; } and… Read more
Ruby Modules
There are two common usages for modules in Ruby: namespacing and mixing in. An example of namespacing can be seen in the Math module: Math::PI # 3.14159…. Math.log10(100) # 2.0 Mixing in a module will extend that class with additional constants and methods. Here’s an example where we’ll create our own module and mix it… Read more

Fun puzzle from Cryptography Research
We got a package from our friends at Cryptography Research today. It was a puzzle inside a puzzle, worthy of being a significant plot device in a Dan Brown novel. It took us several minutes to open, then the real fun began in cracking the cryptography. Date: Wed, Dec 22, 2010 at 2:08 PMSubject: Re:… Read more
