Not too long ago you’ll remember I wrote a full stack tutorial on developing a full stack movie database with the Go programming language. In that tutorial we made use of NoSQL as the database, Golang as the backend, and Angular as the client frontend. However, I realize that not everyone is a Go de...

When building a great application, it is a good idea to plan for proper testing of each of the components that make the application tick. Through unit testing, we can test each function within the application as a separate entity, to make sure it performs based on our testing criteria. But how do yo...

Back when I had just started to learn NativeScript I had created a tutorial for using the native device clipboard for copying and pasting. The previous tutorial demonstrated this functionality in a vanilla JavaScript application. In an effort to clean up any loose ends, I figured it would be a good ...

In pretty much every mobile application that I’ve ever made, I’ve had a need to use some form of alert dialog. The problem with this is that standard alert dialogs are boring and can actually make your application less attractive. This is where Fancy Alerts come in. In NativeScript, there is a plugi...

So I was researching object storage and I came across the open source distributed object storage software, Minio. This lightweight software was written with Golang and accomplishes similar things to that of Amazon S3. After all they are both object storage solutions. The difference here is that Mini...

I am pleased to announce that the latest episode of The Polyglot Developer Podcast has been released to popular podcasting networks such as, but not limited to, iTunes and Pocket Casts. In this episode titled, Getting the Help You Need on Stack Overflow, Blogs, and Forum Boards, I revisit something ...

When it comes to configuring a Raspberry Pi for the first time, there are a few options, many of which can be a pain. This includes configuration of a Raspberry Pi and the smaller Pi Zero. Previously I had written about using a Raspberry Pi as a headless unit, but in that tutorial there was an ether...

With all the technologies and platforms available, it opens the door to infinite possibilities for development and further validates the need of being a full stack developer. There are many stacks in existence, but one of my personal favorites includes Golang, Angular, and NoSQL. So how do you apply...

Back when I had just started working with NativeScript, about a year ago, I wrote a tutorial for displaying Toast notifications in Android. While still valid, it demonstrated these notifications using vanilla NativeScript and JavaScript. Not only that, but the notifications were only for Android. Si...

I’ve been all about websockets lately. Up until recently RESTful APIs have been my whole world, but they don’t accomplish everything and what they do accomplish may not be the best fit. Not too long ago I got my Onion Omega2 Internet of Things (IoT) device with a bunch of accessories and I’ve been p...

Recently I was prototyping an application in NativeScript with Angular, but was feeling too lazy to set up the Angular Router to do multiple page navigation. Typically when I run into this scenario I use the prompt dialog, but this time I needed something more than data input. This lead me to the mo...

More than a year ago when I started playing around with vanilla NativeScript I encountered the camera module. Previously I had even written a tutorial on using the camera in a vanilla NativeScript application. The NativeScript framework has come a long way and now includes Angular support so I figur...

I’ve kept this on the down-low the past few months, but I’m pleased to announce that a chapter I’ve contributed has been included in the incredibly popular ng-book 2! The chapter I’ve contributed is a deep dive into NativeScript development for the Angular developer. After learning every possible th...

It doesn’t just take a good idea when it comes to making a great mobile application. Sometimes it takes a little flair in the user interface department to make a good mobile application into a great mobile application. For example, when you have a user login screen, you could just ask for username a...

I’ve been playing around with sockets and websockets recently. Not too long ago I wrote about creating a real-time chat application using Golang and Angular that made use of websockets. In that example we created a chat server using the Go programming language and a client facing web application usi...

So I was a recent Kickstarter backer for the Onion Omega2 Internet of Things (IoT) device. My package finally came and I wanted to see what I can do with it. My package included the Omega2, expansion dock, and OLED display so I figured it would be cool to write an application that displayed to the s...

I’m an English only speaker, reader, and writer, so when I download an application from iTunes or Google Play, it is going to be in English. There are many people like this, but possibly in a language other than English. When I release my English-only application, how much of the world am I neglecti...

If you’re like me, you run a WordPress blog and are terrified of the thought of something going wrong. With core updates, theme updates, plugin updates, and server component updates, there is a lot of room for error. This is where a WordPress backup could help ease your mind. WordPress recommends ta...

It has been a long year being an advocate of technology and I thought it would be a good idea to share everything that has happened to The Polyglot Developer and all of its networks. Last year, in 2015, I started a tradition of sharing my WordPress, YouTube, and course statistics. We are approaching...

Over the past few years I’ve become dependent on wearable technology, a compliment to my smart phones. For the past year I’ve been using a Pebble Time smartwatch, but since Pebble recently sold out to Fitbit and shutdown shop, I was left looking for a replacement to my soon to be disabled smartwatch...

I’ve been hearing a lot about websockets lately and how they can accomplish real time communication between applications and servers. They act as a compliment and possible alternative to RESTful APIs that have been around for significantly longer. With websockets you can do real time messaging for t...

Continuing down the road of Golang development I thought it would be a cool learning example to develop a URL shortener application similar to that of TinyURL or Bitly. I think these are great examples because not only does it teach you how to develop a RESTful API that uses a datasource, but it als...

Observables. Native To The Web Platform? One of the common misconceptions in the web world is that RxJS is an “Angular thing”. What most developers don’t realize is that Observables are on their way to becoming native to the web, and if you aren’t already using them to handle asynchrony, you are not...

Almost two years ago I wrote an article explaining how to determine if a number is prime or not using JavaScript. It turns out this article became more popular than I thought it would, and if I had to guess, it might be because it is a good computer science and overall interview question for new car...

I figured I would change it up a bit and get into the basics of Golang and common Computer Science study material taught in school, but often used in software engineering type positions. We’re going to revisit a post I wrote back in 2015 regarding the Fibonacci number and generating the sequence in ...

CSS is usually a subject I avoid due to me being artistically illiterate, but recently a student of mine asked me an interesting question regarding theming an Angular NativeScript application with dynamic CSS files loaded at runtime. Given the nature of Angular, it becomes difficult to load files at...

I recently received a request from one of my followers for a tutorial on using Google Admob in a NativeScript Angular application. Not too long ago I had demonstrated Google Admob in a vanilla NativeScript project, but I hadn’t yet given it a shot with Angular. In case you’re unfamiliar with Admob, ...

After months of receiving requests, I am finally pleased to announce that my course, NativeScript for the Angular Developer, is now available on Udemy. This Angular and NativeScript course is similar to the previous course I released titled, NativeScript 101, with the exception that this time we’re ...

Sending emails from your mobile application is often a critical aspect. For example, what if you want to be able to collect user feedback, wouldn’t email be one of the better solutions? Now let’s add to this scenario and say that the user doesn’t have email configured on their mobile device. How doe...

I’ve been keeping up with Angular since the beta releases and if you have too you’ll know that navigation has changed about one hundred times between then and the now stable release. Navigation with the Angular Router component is a tricky subject, but understanding it is necessary for pretty much e...
