Leveling up with Git

This past weekend I got to spend 4 days at the Ruby for Good event. This is an event where programmers get together and volunteer their efforts in charitable programming for many needs in our communities. The team I joined up with consisted of 10 developers and most of the team grouped together in about…

101 Ruby Code Factoids

0) ‘methods’ method Since almost everything in Ruby is an Object you can type dot methods on it to see what methods are available.


4.methods - Object.methods
# => [:-@, :+, :-, :*, :/, :div, :%, :modulo, :divmod, :fdiv, :**, :abs, :magnitude, :~, :&, :|, :^, :[], :<<, :>>, :to_f, :size, :bit_length, :zero?, :odd?, :even?, :succ, :integer?, :upto, :downto, :times, :next, :pred, :chr, :ord, :to_i, :to_int, :floor, :ceil, :truncate, :round, :gcd, :lcm, :gcdlcm, :numerator, :denominator, :to_r, :rationalize, :singleton_method_added, :coerce, :i, :+@, :remainder, :real?, :nonzero?, :step, :quo, :to_c, :real, :imaginary, :imag, :abs2, :arg, :angle, :phase, :rectangular, :rect, :polar, :conjugate, :conj, :between?]

Introspection by Design in Ruby

If I have one pet peeve in Ruby it’s knowing state at a certain point in the program’s process. Sure they make plugins for advanced diagnosis of this. And when you start out learning to program it’s common practice to use puts everywhere to see what’s going on. But this causes a lot of back…

Ruby Refinements – Not quite ready for production

I recently looked for a method on Array for a boolean response on its uniqueness. As Ruby currently doesn’t have one I figured it’s easy enough to write one. Now Ruby’s refinements are fairly new and a nice feature to have around. So I decided to write a benchmark for different ways to test the…

Rails Before I started using Rails I was the guy who would type out web projects by hand… I was accustomed to it. I knew what I was working with all the time simply because I wrote it. When I had started reading the docs on Rails I was trying to learn it in this…

Rails Helper Methods

When I had started developing in Rails it was months before I even heard of “Helper Methods”. I did see the folder in the app directory, but I didn’t see any use for it at the time. I mean Rails is pretty much Model-View-Controller, so why would anyone need helper methods? Well once I found…

Learning Your First Programming Language

If the idea of designing software intrigues you; then you’re in the right place. Often times the things that keeps you from moving forward is the “fear of the unknown”, or simply doubting your ability/capacity to learn. If programming looks like some big ominous thing and like it’s more trouble than it’s worth, then you…

“Assume Everything Will Break” Development

In Ruby, and Ruby on Rails, the community is very big on Test Driven Development (TDD). This is good! And it’s especially important when working with a team. But what patterns will you develop in buidling a huge Rails application on your own without tests? Well I’d like to call it “Assume Everything Will Break…
