Note: This post is in response to a client asking why a single state store is preferable to a more object-oriented approach with multiple objects, each managing its own state. -------------------------------------------------------------------------------- First, a caveat: I don't have much hands-on experience with React, and I've never used

Thoughts On Setting Up A Greenfield Node Project

Basic Setup The choice is between a "traditional" server-side rendering setup or and API server with client-side rendering. I'm aware of full-stack frameworks like Meteor [https://www.meteor.com/], but that is complete overkill, at least for my current project. I'm looking for something

Functions Versus Methods

When I first started programming, I remember encountering functions and methods. I was familiar with functions from high school algebra, but I had no idea what a method was. They looked similar to functions, and online comments indicated they were essentially interchangeable. When you are getting started, you can think

However attempting to run the project failed with a :dexDebug error. ``` com.android.dex.DexIndexOverflowException: method ID not in [0, 0xffff]: 65536 Error:Execution

I've been working on my first AngularJS [http://angularjs.org/] project since October. It has some strangeness, but on the whole I am impressed. Pros * Single language. I normally work with Ruby on Rails [http://rubyonrails.org/] , which means some JavaScript is inevitable. Now I'm writing
