Recently I’ve had to rewrite portions of a PHP legacy application that was written in a company’s proprietary legacy framework, in order for it to be test friendly and much more maintainable. In order to accomplish this, I’ve added a few key Symfony components to their framework. The result was that the application was easier
In my development environment I’ve been using Vagrant with Virutalbox for a while now; however, even with NFS, with the VM properly provisioned with enough resources, and running under Linux, the environment’s performance was still just barely tolerable. It’s performance compared to Ubuntu natively on a Samsung 850 pro SSD left me wishing for more..
Node.js relies on asynchronous Input and Output (I/O) in order to increase the computing efficiency and speed of an application. This article will take a basic look at what asynchronous programming actually means, and why asynchronous I/O is important in a language like Node.js. For Node.js performance to be actualized, a certain programming paradigm must
Everyone always talks about the Node.js event loop and how its important, but what exactly is it responsible for? Well… Let’s take a look! 😀 The event loop (event queue) in Node.js is a loop that is responsible for processesing incoming requests. This loop “contains” a queue of requests, and each request in the event
JavaScript Invocation patterns can be tricky for developers new to the language. This tutorial will take a look and review the four different invocation patterns that JavaScript offers, and the behavior that is expected when using them. A function invocation in JavaScript refers to passing control and parameters to another function during execution. This may
Running a Node.js application along side other non node web applications can work well if configured correctly. This tutorial will show you how to easily configure a Virtual Host to proxy Node.js application requests through Apache. First, we need to make sure that we have Node.js running on a port other than the port Apache
JavaScript Async & Callbacks Asynchronous calls and callbacks are how JavaScript is able to respond to user events that occur after the browser has loaded the DOM. This type of programming is commonly referred to as event-driven programming. In event-driven programming, once an event occurs, its registered callback to that event fires off its functionality.
Replication in MySQL is keeping databases somewhat “in sync”, minus the latency at least.. So let’s pray to the computer gods (maybe Ava in Ex Machina?) 🙂 that we don’t run into any weird, complex, race conditions.. There are multiple ways to do data replication in MySQL and if your database isn’t very big, then
The Decorator Pattern is a highly used Object Oriented structural design pattern, that gives the ability to attach additional responsibilities to an object dynamically, without sub-classing. When this pattern is used correctly, it can be extremely powerful due to the flexibility it offers. So… Grab yourself a cup of coffee, or better yet… Some of
