Server-side I/O Performance: Node vs. PHP vs. Java vs. Go

By Brad Peabody

Understanding the Input/Output (I/O) model of your application can mean the difference between an application that deals with the load it is subjected to, and one that crumples in the face of real-world uses cases. Perhaps while your application is small and does not serve high loads, it may matter far less. But as your application’s traffic load increases, working with the wrong I/O model can get you into a world of hurt.

ARM Servers: Mobile CPU Architecture For Datacentres?

By Nermin Hajdarbegovic

Boring. That’s a word many people use to describe the server industry, although unexciting and uneventful would be a better fit. This is not necessarily a bad thing, because when something “exciting” happens to a server, it usually involves blue smoke and downtime. Luckily, the server space is about to get a bit more exciting, thanks to the introduction of servers based on ARM processors. In this post, Toptal Technical Editor and resident chip geek Nermin Hajdarbegovic explains why ARM processors could end up powering a server near you, and what this means for the software industry. The potential implications of ARM servers are huge, but there is no cause for alarm. This industry segment does not tend to evolve fast, and developers will have plenty of time to get ready.

Bottle is a minimalist Python web framework. It is lightweight, fast, and easy to use, and is well-suited to building RESTful services. In this article, I'll provide a walkthrough of how to build a RESTful API service using Bottle.

How to Use Rails Helpers: A Bootstrap Carousel Demonstration

By Carlos Ramirez III

One of the most misused, misunderstood, and neglected of all the Rails built-in structures is the view helper. Helpers often get a bad reputation for being a dumping ground for one-off methods used across the entire application's view layer. But what if your helpers could be more semantic, better organized, and even reusable across projects? What if they could be more than just one-off functions sprinkled throughout the view, but powerful methods that generated complex markup with ease leaving your views free of conditional logic and code? Let's see how to do this when building an image carousel, with the familiar Twitter Bootstrap framework and some good old-fashioned object-oriented programming.
