When building a NativeScript application with Angular, there are certain scenarios where you might want to share functions and variables across the pages of the application. There are other scenarios where you might want to pull similar functions into a class for code cleanliness. Both of these scen...

I don’t typically write product reviews, but since I’m a huge advocate for the Internet of Things (IoT) and smart home technologies, I think it makes sense to share some opinions. I own an Amazon Echo and a second generation Amazon Echo Dot. Today (November 4th), I received my Google Home that start...

Continuous integration (CI) and continuous deployment (CD) are terms that I hear thrown around quite frequently. I’ve been a software developer for a long time, but it is only recently that I’ve welcomed these terms into my life. CI and CD is the automated process of running various tasks such as un...

I recently wrote about how to use a SQLite database within a NativeScript Android and iOS application that was built with Angular. This was more or less a revisit to the vanilla NativeScript tutorial on the same subject I had written earlier in the year. What happens when you have a massive amount o...

Quite a bit of time ago when I first started using NativeScript, I wrote a tutorial around using a SQLite database with it. Now just to be clear, this was with vanilla NativeScript, before Angular was available. Heck, the previous article was using JavaScript and not even TypeScript. Well, times hav...

I recently wrote a tutorial for navigating a NativeScript Angular application using the Angular Router. In this tutorial I demonstrated how to create a multiple page application, navigate between pages, and even pass simple string parameters between the pages during navigation. However, what happens...

Unless you want a very boring single page application, you’re going to want some form of page navigation with multiple pages available. Previously I wrote a tutorial for navigating between routes in a vanilla JavaScript NativeScript application, but with Angular in full force, it probably makes sens...

As someone who has developed both hybrid web applications and native applications, I understand the differences and advantages each brings to the table. While I agree that you can do some pretty neat things with a hybrid web application built with frameworks like Ionic, I no longer think it is as gr...

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 De...

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 wer...

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 c...

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 Do...

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 ever...

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 ...

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. Ho...

A few years back I created an Android and iOS application called OTP Safe that managed time-based one-time passwords. This application was made with the first version of Ionic Framework and at the time was great because it accomplished more than the Google Authenticator application. Now that Ionic 2...

As you know from the guides that I put out, I’m a Raspberry Pi collector. I collect the full size units as well as the Pi Zero units. In a previous post I explained how to emulate ethernet over a USB as a way to connect to a Pi Zero that is not using WiFi or ethernet. However, what happens when you ...

By now you’re probably aware that I’m all about Amazon Alexa skills since I’m a proud owner of an Amazon Echo. I had released a Alexa skill called BART Control and published a guide on creating a simple skill with Node.js and Lambda. If you went through my Node.js and Lambda guide you probably found...

Writing tests is a very important part of mobile application development, but not everyone does it. It could be laziness, it could be because you don’t know how. I fall into the category that I’m often too lazy to write tests. I don’t have time to write tests, I just want my application done. That i...

When it comes to modern JavaScript development, there are a few different ways to handle asynchronous events or data. You could use promises and callbacks, but as great as they are, present certain limitations. This is where RxJS comes into play with its reactive programming model. In this episode o...

Recently I published my first skill for Amazon’s Alexa voice service called, BART Control. This skill used a variety of technologies and public APIs to become useful. In specific, I developed the skill with Node.js and the AWS Lambda service. However, what I mentioned is only a high level of what wa...

Ionic Framework has been around for a few years now and has completely changed the way people develop hybrid mobile applications. With Angular out and Ionic 2 nearing stable release, the Ionic 1 and AngularJS predecessor will be a thing of the past and forgotten. What if you’ve gone all in with the ...

When it comes to saving data in an Ionic 2 mobile application, there are many ways to get the job done. You can use the classic HTML5 local storage, but run the risk of compatibility problems between all available devices. You can use SQLite, which is part of Ionic Native, but that will only work fo...

Not too long ago I wrote an article regarding how to create a RESTful API using the Go programming language, but in it I only used mock data rather than an actual database. What happens if we want to use a database with Golang? What database, or more importantly, what kind of database should be used...

When it comes to Ionic 2 there are many ways that you can store your data. For example you could use HTML5 local storage, Mozilla’s localForage library, or Ionic’s SQLite extension that is part of Ionic Native. With these options available, I get a lot of requests for information on Ionic’s less adv...

So I recently picked up some more Raspberry Pi 3 units. You’re probably thinking I’m building my own T1000 (Terminator reference) with these things. No, actually I got these units for work to play around with some IoT projects around the office at Couchbase. I have a few offices that I visit at Couc...

When it comes to software development there are many different items to develop for. I’ve spent most of my developer life creating applications for the web, desktop, and mobile, but when it comes to possibilities it doesn’t end there. In recent years the Internet of Things (IoT) has been taking over...

I’ve written a few articles about how I’m using my many Raspberry Pi units. Recently I wrote about using a Raspberry Pi as an automatic network backup server, but I didn’t talk about expanding the storage beyond the micro or standard sized SD card. What if you want to utilize a much larger USB hard ...

Angular is all the rage right now. It is a significant step in the right direction from its predecessor AngularJS 1 for numerous reasons, one being its decoupling from the document object model (DOM). This separation allows for applications to be built beyond the web browser. Take for example, the m...

I play around with iBeacons quite frequently. I created my own Internet of Things (IoT) iBeacon project as well as an AngularJS wrapper for using iBeacons in an Ionic Framework application. This time around I figured I’d take my iBeacon adventure to the next level and try to use them in a native And...
