    RubyMotion is a framework that lets you build iOS applications in Ruby. It gives you all of the benefits of the Ruby language, but because the code you write is compiled to machine code, you gain all of the raw performance of developing in Objective-C. In this tutorial, you'll build a painting application from scratch. I'll show you how to incorporate Interface Builder into your workflow and how to properly test your application.Read More…

    Using simple SQL queries to retrieve data is, at times, not the most efficient and scalable way of performing search operations in an application. Using a full-featured search engine can save you from writing a lot of code and also from your application suffering in performance.

    Writing Robust Web Applications - The Lost Art of Exception HandlingRails education retina preview2
    56 shares
    As developers, we want the applications we build to be resilient when it comes to failure, but how do you achieve this goal? If you believe the hype, micro-services and a clever communication protocol are the answer to all your problems, or maybe automatic DNS failover. While that kind of stuff has its place and makes for an interesting conference presentation, the somewhat less glamorous truth is that making a robust application begins with your code. But, even well designed and well tested applications are often lacking a vital component of resilient code - exception handling.Read More…

    When you first get introduced to New Relic, it's easy to be overwhelmed by all the features. But like with most tools, as you slowly climb the learning curve and get familiar with the features provided out of the box, you begin to wonder how it all hangs together under the hood and if there is more you can do with what you have at hand.Read More…

    5 Reasons Why New Relic Is a Developer's Best Friend34932
    27 shares
    Once you start digging around New Relic you begin to realise just how many interesting features the service has to help monitor the performance and health of your application. It was truly difficult to pick just five things to talk about, so rather than focusing on the obvious features let's look at some of the less hyped functionality that New Relic provides and how we can use it in interesting and sometimes unorthodox ways. When we left you last time, we had a basic 'Hello World' Rails application (called New Relic_rails1, living in ~/project/tmp/New Relic). We will continue using this app, extend it and see if we can use it to demonstrate the features of New Relic that we'll be looking at.Read More…
