If you’re a fan of the Raspberry Pi, you might have stumbled upon my tutorial for interacting with a Raspberry Pi Zero using nothing more than a USB cable. If you recall, the standard Raspberry Pi Zero has no WiFi, no Bluetooth, and no Ethernet. Alright, so let’s assume that you’re able to interact ...

A couple of days ago, while recovering from some flu, I managed to catch up a bit of me reading. If you know anything about the life of an independent contractor, you’d know that there’s never time for your personal projects or hobbies, so this was a most welcome break. One of my favorite blogs is t...

When building a web application there is a good chance you’re going to need to work with images eventually, even if it is something as simple as allowing a user to upload a profile image. In theory this is a simple task, but in reality, your website theme is probably anticipating images of a certain...

Amazon and a lot of cloud vendors such as Microsoft and Google have services around machine learning (ML), artificial intelligence (AI), and virtual assistants. A popular one that might come to mind is Amazon Alexa, something I’ve written quite a few tutorials around over the years. The concept arou...

I recently wrote a tutorial titled, Configuring Visual Studio Code for Arduino Development, because I’ve been exploring the Internet of Things (IoT). Up until recently I’ve only had hands on experience with Raspberry Pi, but I’ve been expanding my knowledge with Arduino. I have an Arduino Uno and a ...

I’ve been playing around with an Arduino Uno recently, something new to me since I’ve always only used Raspberry Pi hardware. Many Arduino devices, or at least the Uno like I have are inexpensive and a lot of fun to play around with. However, the development experience out of the box isn’t exactly w...

When building an application that allows users to have accounts, you have to ensure that access to these accounts is secure. When building a user account system, an important factor to keep in mind is how passwords are stored. Storing passwords as plain text is a complete rookie move that leaves you...

If you’re studying computer science, at some point you’re going to be exposed to the Quicksort algorithm. Even if you’re not a computer science student, chances are this particular algorithm will come up at some point in time as part of an interview. I’ve been asked about it plenty of times in inter...

Dart is a programming language developed by Google and made popular by Flutter, their mobile development framework for cross-platform application development. The Dart language is a general-purpose language, built to be used for far more than just mobile development, and, in this short tutorial, I w...

When it comes to the fundamentals of computer programming, arrays will almost always make an appearance. Being able to store a collection of values could be beneficial to a near endless amount of use-cases. To continue the back to the basics programming series, in this tutorial we’ll explore standar...

When it comes to client and server communication, there are quite a few approaches towards solving the problem. You could create a RESTful API or GraphQL API on your server and consume it on-demand with your client, or you can go the socket approach and interact in real-time through events. There is...

In this back to the basics tutorial, we’re going to be exploring loops in C++, something that you’ll take with you well into your software development career, regardless of programming language. The content in this tutorial is targeted at new developers or those that would like to start learning C++...

The latest episode of The Polyglot Developer Podcast has been published and it is the first one on the show to be on the topic of game development!

I mentioned a few months ago that I was going to periodically go back to the basics when it comes to computer programming and application development. Building a Hello World Example C++ Application was a first example of what I was talking about. However, in this previous example, much of our work w...

As you know, The Polyglot Developer is a static generated website that is built with Hugo. Given the nature of static generated websites, they are generally much faster than the CMS alternatives, but just because they’re fast, doesn’t mean they pass all of Google’s tests by default. In an ongoing ef...

When working with Go or any programming language for that matter, there is almost aways a need to validate the data that the user provides before you start working with it or storing it in a database. A sloppy way to validate data would be to use a series of if/else conditions, switch statements, an...

As you might know, sponsored advertisements are one of the things that are funding The Polyglot Developer and everything it accomplishes, so keeping sponsors happy and supplying them the metrics they need is very important. However, in most circumstances, more specifically when it comes to banner cr...

Almost two years ago I had written a tutorial around 2FA in a Node.js API with time-based one-time passwords. If you’re unfamiliar, two-factor authentication is becoming the norm, which it wasn’t necessarily back in 2017. If you’re managing user accounts in your web applications, it is critical that...

I am pleased to announce that the latest episode of The Polyglot Developer Podcast is now available on pretty much every popular podcast network. This episode, which is episode 25 of the show, is all about two-factor authentication (2FA) and the things you should be familiar with when it comes to im...

While I haven’t done too much with Serverless Framework and Functions as a Service (Faas) recently, I did in the past and it isn’t something that I’ve forgotten. In the past I demonstrated how to deploy Node.js functions to Amazon Web Services (AWS) Lambda that contain native dependencies. While not...

While REST APIs are amongst the most popular when it comes to client consumption, they are not the only way to consume data and they aren’t always the best way. For example, having to deal with many endpoints or endpoints that return massive amounts of data that you don’t need are common. This is wh...

If you’ve been following along, you’re probably familiar with my love of Node.js and the Go programming language. Over the past few weeks I’ve been writing a lot about API development with MongoDB and Node.js, but did you know that MongoDB also has an official SDK for Golang? As of now the SDK is in...

To continue on my trend of MongoDB with Node.js material, I thought it would be a good idea to use one of my favorite Node.js frameworks. Previously I had written about using Express.js with Mongoose, but this time I wanted to evaluate the same tasks using Hapi.js. In this tutorial we’re going to de...

One of the most powerful commands that you could learn, grep is essentially a robust search tool. It gets its name from the acronym it stands for which is global regular expression print. This is just a fancy way of saying “to search for specific strings or patterns (using regular expressions) withi...

When creating a web application that handles user information it is a good idea to protect anything considered sensitive rather than storing it as plaintext within a database. The goal is to make it as difficult as possible for a malicious person to obtain access to this sensitive information. Rathe...

As you know, based on a few of the tutorials that I’ve published recently, I have a YubiKey that I’ve been learning how to take full advantage of. In previous tutorials I demonstrated how to implement U2F in your web application, but most YubiKey devices do so much more than just U2F authentication....
