IOT RECIPE 1: ARDUINO YUN + MONGODB + D3JS
Abstract I briefly talked about this solution in my introduction to this series but wanted to dive into more details here. Let's start with my current favorite Microcontroller, the Arduino Yun. You may recall this MCU has both a Arduino and a Linux processor, and we will be using both. On the Linux side we will write a simple agent in Node. This agent will get sensor values and POST them to our

Ionic – The Application Layout
In Part 3 we created the basic service for making API calls to get challenge data. In Part 4, let's talk a bit about our final application layout. This post is part of an ongoing series: Part 1: Dip Your Toe In Part 2: A Few of My Favorite Things Part 3: The API Service Part 4: Application Layout Part 5: Wiring Up the Search Screen Layout Ok - we've got some building blocks in place now, so

I Got Engaged With Swift
Misleading title alert: I didn’t get engaged to Swift, but Swift certainly had a place in my recent engagement. The story that follows is about how I am a sap, a geek, and a mediocre coder. I consider myself a very lucky guy. Many years ago I met a wonderful woman who accepts me for all my geeky qualities and supports me in all my ridiculous endeavors. I’ve known for years she would become my

Swiftly Build Your Cred in Our New iOS Topcoder Community
In today's world, I've seen recruiters ask for 5 years of Swift programming language experience despite the fact the language itself is only been out for a little over a year! Demand for Swift experience is clearly on the rise. Which is why we are excited to announce our first vertical community focused solely on iOS (iOS.topcoder.com). Here you'll be able to show your skills, compete in real

Node-RED for Topcoder Challenges with IBM Bluemix & Watson
For the past week I’ve been obsessed with Node-RED. If you are not familiar with it, Node-RED is an open source IBM technology for “wiring together hardware devices, APIs and online services in new and interesting ways”. Since Node-RED is built on Node.js, this makes it ideal to run at the edge of the network on low-cost hardware such as an Arduino or Raspberry Pi as well as in

A #Swift Series Part 3 – A Little Bit of Init
This time around, I want to talk about a complicated topic, initializers. I want to scratch the surface, perhaps go a little bit deeper, but not overwhelm you with too much information. To this end, I’m going to provide a framing device for initializers first then some appropriate context that will help you better digest (no pun intended, as you’ll soon figure out) how initializers work. Some

Five Time-Tested Tips for Beginning Developers
It’s always hard to learn something new, and programming is no exception. It’s unlike anything you’ve ever done in school. You might’ve learned a foreign language or two, but none are constructed or used like programming is. For example, if you learn Spanish, you might have to write a short recipe for making peanut butter and jelly sandwiches. All you’d have to do is find the right

Deliver Better User Experiences with the IBM Design Language
When looking to learn about design — specifically design languages and patterns — there is no one-size-fits-all solution. And as members of the Topcoder Studio Community, you aren’t simply looking to design to impress, but to solve real business problems. The IBM Design Language can help our community have a common core language/design base. Understanding IBM’s six universal experiences

Ionic – The API Service
In Part 2 we did some configuration and setup some useful addons. In Part 3, we'll get started in earnest and create a service to make the API calls for our app and track the results. We'll be querying topcoder challenge data. This post is part of an ongoing series: Part 1: Dip Your Toe In Part 2: A Few of My Favorite Things Part 3: The API Service Part 4: Application Layout The Challenge

New IBM Fun Challenge with Node-RED and Watson Translation Services!
We are kicking off another sweepstakes type challenge with IBM Watson and Node-RED. What is Node-RED you ask? Think of it as Unix Pipes or the old Yahoo! Pipes on steroids. It’s an easy to use drag-n-drop interface to connect lightweight nodes to process streams of events. We put together a quick demo to get you stated. The app takes audio from an existing file (.WAV) or your
