Index Your Foreign Keys

We add indexes to our database in order to speed up read operations. Basically, an index is a sorted copy of a particular set of columns the database uses to quickly look up the attributes of another table, most commonly, foreign keys of relations. There are several ways this can actually be implemented on the database; essentially, we tell the database which values we’ll be looking up most often and »

ActiveRecord Associations & You

I love abstraction. It’s great to compartmentalize complexity and keep your application modular. SQL is not that. Relying on SQL strings in your code ties your implementation directly to the type, structure, and even the version of your database. ActiveRecord (the ORM behind Rails) is great for letting us focus on our application and not worry so much about the database particulars. However, understanding »

(Over)simplify Your Code

One of my eureka moments as a developer came when my programming pair suggested I separate some very simple math in the body of a method into another method. At the time it seemed like overkill to create an entirely new method when the operation was so simple. Wouldn’t that make it more complicated? But I quickly realized the benefits outweighed the cost. The first benefit is code reuse. This is rather »

Open + Download Native Apps with a PhoneGap/Cordova Plugin

Are you working on a PhoneGap/Cordova app that needs to be able to communicate with other native applications? You may want to get the demo code, maybe give it a once over, and then continue reading. Note: This work was completed in a pre-PhoneGap 3.0.0 world. There is now a Plugin Specification Guide that should be adhered to. This code would need to be adapted to fit that structure. Prologue »

Tips for Novice Developers (and why you should become a rubyist)

Work Locally Working locally means that you have an instance of your web app running on your machine. You edit files directly on your machine, rather than uploading every change to the server. It is tempting to edit files directly on your shared server, but don’t do it! It is a very bad practice and will bite you over and over again if you let it become habit. You may start out thinking of a website »
