TPDP Episode #10: All About The Google App Engine

October 3, 2016 Nic Raboy

There are a few different ways to host applications online. You can spin up your own VPS or container, but those are not easily scalable. Instead there is a nifty service called Google App Engine that is designed for scalable web applications at a very cheap price. In this episode of The Polyglot Developer Podcast, I have guest speaker Terry Ryan from Google to help spread the word on all the things Google App Engine can accomplish and why you should use it.

Build A Time-Based One-Time Password Manager With NativeScript

September 30, 2016 Nic Raboy

Not too long ago I released a time-based one-time password manager called OTP Safe to Google Play and iTunes. That particular application was built with Ionic Framework and I even wrote a tutorial explaining how to make a similar 2FA manager with Ionic 2. Being a hybrid mobile application, there were some performance limitations that came with the Ionic 2 application. This inspired me to convert the application to something native and NativeScript seemed like a solid solution.

Let’s take time-based one-time password management to the next level and create a native mobile application with NativeScript and Angular.

Scan For Bluetooth Enabled iBeacons Via A Raspberry Pi IoT Device

September 26, 2016 Nic Raboy

Lately I’ve been working a lot with iBeacons and Raspberry Pi Internet of Things (IoT) devices. I’ve been building an office monitor for logging foot traffic around the office. I planted a few Raspberry Pi devices around the office and distributed some Gimbal iBeacons to a few of my coworkers so I could determine what part of the office experiences the most heat.

While Raspberry Pi 3 devices come with integrated bluetooth, Raspbian Linux is not configured to support BLE scanning. There are a few packages that must be installed to make BLE scanning possible.

We’re going to see what is necessary to scan for BLE iBeacons using a Raspberry Pi with Raspbian Linux installed.

Deploying Docker Containers On A Raspberry Pi Device

September 19, 2016 Nic Raboy

Recently I’ve been using a good amount of Docker for various deployment pipelines. As everyone knows, I’m a huge Raspberry Pi fan, so I figured it would be a cool idea to bring the two together. After all, Docker was built using Golang which is cross architecture.

We’re going to see how to create Docker containers on a Raspberry Pi and figure out the limitations of using Docker on IoT based architectures.

Record IP Camera Surveillance Video With A Raspberry Pi

September 5, 2016 Nic Raboy

As some of you may know, I have wireless surveillance cameras around my home. Many years back I even released an Android application called SpyFi to be able to view the video feed from these cameras. Up until recently I would have these cameras upload a sequence of images to a remote FTP server every time there was motion. The problem with this is that these were only a sequence of still-images rather than video, and the server was not free or necessarily cheap.

Being that I own a few Raspberry Pi computers, I figured it might be a good idea to utilize them for surveillance storage. The cool thing about this approach is that it is cheaper and that I can record video rather than pictures.

We’re going to take a look at how I’m recording video on a Raspberry Pi device to keep my home safe.

TPDP Episode #9: An Ember In The Land Of Web Frameworks

September 3, 2016 Nic Raboy

We’re nearing the end of 2016 and there are many JavaScript frameworks available to choose from, with more on the way. Each framework offers a unique perspective of front-end development that can be very attractive to solo developers or development teams. This brings us to a very popular JavaScript framework called Ember.js. In this episode of The Polyglot Developer Podcast, I have guest speakers Tracy Lee and Taras Mankovski, who are both Ember experts.

Tracy Lee is a very successful JavaScript developer who sold her start-up and now focuses on her web organization Modern Web, which educates people on different development technologies. Taras Mankovski runs a very popular consulting business called Ember Sherpa which also educates businesses on the Ember.js framework. In the ninth episode of this podcast, An Ember in the Land of Web Frameworks, we explore Ember and the conveniences it offers in the realm of JavaScript and front-end development. This exploration includes tooling and comparisons against other popular frameworks like React and Angular.

Use Mozilla’s LocalForage For Key-Value Storage In Ionic Framework

August 29, 2016 Nic Raboy

A few years ago I wrote an article called Use ngStorage for all Your AngularJS Local Storage Needs, which was intended to be for AngularJS in general. However, I understand many readers were using it in their hybrid Apache Cordova or Ionic Framework applications. There is nothing wrong with this. However, ngStorage is a wrapper for HTML5 local storage which is known to have compatibility issues under certain circumstances. That said, came across localForage, a library by Mozilla, which claims to be a wrapper for local storage, WebSQL, and IndexedDB, offering maximum compatibility.

We’re going to take a look at including localForage in an Ionic Framework Android and iOS application for storing data.
