Ruby Chops: Flexible Sort

So I was messing with the comparable module and the <=> method.  I implemented as I would in Java.  Then I played with sort_by and thought that was awesome. Which led me to writing my own method that would allow me to pass in a collection and attributes to be sorted by. The objects in the collection would have to implement my Sortable module. This was more for academic fun and try to keep my mind sharp. If anyone sees a cooler way to do it then please post it here.

My experience of using Sinatra on my Mac was straightforward. Like most things using Ruby and Mac: it just worked. However, I found out the students at the high school use MS Windows. Fortunately, I have a Windows XP virtual machine running in VMWare so I could prepare that way. I used to teach computer science and web development at Spokane Community College and am aware of teaching Ruby in a Windows lab environment. …

AngularJS 101: A Beginner's Tutorial

Below is the PDF article I submitted to Software Developer's Journal for their series they did on AngularJS.

It's behind a paywall and thus hidden from most of the world. That sucks... which is why I'm posting my article here for all to see.
