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.

Simplified NGINX Load Balancing with Loadcat

by Mahmud Ridwan

NGINX, a sophisticated web server, offers high performance load balancing features, among many other capabilities.

Go Programming Language: An Introductory Golang Tutorial

by Brendon Hogger

Go is a relatively new language with a number of attractive features. It's great for writing concurrent programs, thanks to an excellent set of low-level features for handling concurrency. In many cases, though, a handful of reusable abstractions over those low-level mechanisms makes life much easier. This introductory tutorial walks you through building one such abstraction: a wrapper that can turn any data structure into a transactional service in Go.
