Mobile development is a necessity for every modern business, but there are many ways to get the job done. Many will tell you to go pure native, some will tell you to go hybrid, and others will tell you to use a framework to go cross-platform native. We’re going to review my top three picks for mobil...

In this tutorial we will build a simple Vue.js application which will demonstrate the power of using Vuex as a central data store, where the data will be asynchronously retrieved using Axios for the API requests. A basic level of HTML, CSS and JavaScript will be beneficial but is not required. The p...

I’ve been developing applications both as a hobby and professionally for quite some time now. I’ve released top ranking mobile applications to the various app stores and even sold the rights to applications. One question I get asked quite a bit is in regards to how I come up with those ideas and exe...

Sometimes the best examples towards learning a new framework is through a simple user login sample. Login involves many concepts, including forms, data binding, routing, and potentially HTTP to a remote service, all of which are core concepts in any web application. We’re going to see how to impleme...

When working with single page web applications (SPA), chances are you’re going to be using a router or some kind of parent and child component structure. In these scenarios, the parent components probably hold their own functions and variables that may at some point in time need to be accessed by th...

As you may or may not know, The Polyglot Developer is currently using Hugo, which is a static site generator. When getting started with Hugo, the themes and documentation don’t say much when it comes to having more than one possible author producing content. For example, as mentioned in my previous ...

Over the past month or so, in my free time, I’ve been working towards creating an affordable hardware wallet for various cryptocurrencies such as Bitcoin. Right now many cryptocurrency enthusiasts are using the Ledger Nano S hardware wallet, but those are very expensive and rarely in supply. I own s...

About a month ago I had written about creating and importing private keys as well as generating public addresses for Bitcoin and several other cryptocurrencies using the Go programming language. This previous tutorial had more of an emphasis on creating cryptocurrency wallets with Golang than anythi...

Earlier this month I had written a tutorial for detecting nearby BLE iBeacon devices using a Raspberry Pi Zero W and an application written with Golang. It was a great example of accomplishing something with Go and very little code. Scanning for BLE devices is a great use case for Internet of Things...

A few weeks ago I thought I’d try to install Node.js on my Raspberry Pi Zero W to use it as a simple API server that I could take with me on the road. I have installed Node.js so many times before, including on a standard Raspberry Pi, that I figured it would be just as easy to do on the Pi Zero. I ...

I don’t typically write about these topics since they aren’t on the subject of development and operations, but this week Google AdSense put my account on restricted probation for violating its policies, something I hadn’t intentionally planned on doing. After receiving an email from Google and visit...

As you’re probably well aware from my previous Raspberry Pi articles, I’m a hoarder. I have several Raspberry Pi Zero as well as the wireless edition and various attachments that go with them. When I was first getting started with the original Pi Zero, I had a tough time trying to figure out how to ...

Over the past month or so I’ve demonstrated how to generate address information for a variety of cryptocurrency Altcoins using technologies like Node.js, Vue.js, and Angular. The thing about my previous tutorials are that they all used the JavaScript stack in some sense. What if we wanted to adventu...

I am pleased to announce that the latest episode of The Polyglot Developer Podcast is now available for download. The episode titled, Going FaaS on Serverless with OpenWhisk focuses on the development and deployment of functions to be deployed on a serverless cloud platform. In this episode I’m join...

Being able to encrypt and decrypt data within an application is very useful for a lot of circumstances. Let’s not confuse encryption and decryption with hashing like that found in a bcrypt library, where a hash is only meant to transform data in one direction. Not too long ago I wrote about in a pre...

When you’re building a business, the experts all say that you should make your list building strategy a priority. Using social networks like Twitter and Facebook for your marketing is great, but those might not be around forever. Email has been around for a long time and it will likely exist a long ...

After having thought about it for quite some time, I’ve finally decided to start a developer user group in my home town of Tracy, California. This group titled, The Tracy Developer Meetup, was started to give developers living outside of the Bay Area, a chance to collaborate with other developers in...

With Android and iOS so obtainable and development so easy, people often forget the importance of desktop applications. I have a phone and tablet, but I depend on my desktop applications much more. However, the development of these applications are not difficult. With frameworks like Electron, devel...

As you’ll recall, The Polyglot Developer was once using WordPress. Back when I was using WordPress, I was using a plugin called Icegram, which is similar to SumoMe and OptinMonster, but it allowed me to present popups after a period of time to prompt users to subscribe to my newsletter. I get that n...

Last year I had worked on an interesting project at my day job, Couchbase, where I scanned for BLE iBeacon devices from a few Raspberry Pi IoT devices and uploaded the information to a remote server for analysis. I wrote about this experiment in an article titled, Collecting iBeacon Data with Couchb...

Continuing down my adventure of learning about and investing in various cryptocurrencies, I thought I’d explore Stellar, which is what I understand to be, a competitor to Ripple. If you’ve been keeping up, you’ll remember that I had written about creating a Ripple XRP paper wallet in a tutorial titl...

Job hunting can be one of the most time and energy consuming tasks we have to do. Unfortunately there isn’t a perfect formula but some tips could definitely help to alleviate the process or at least know that you are not alone. In the following article I will try to provide you with some tips and tr...

Charts are a great way to illustrate data within an application. No one likes trying to make sense of raw data or looking at it via a table. Instead a nice bar chart or line graph can paint a perfect picture of what’s going on. There are a lot of charting libraries available, but my personal favorit...

To continue on my technical journey of cryptocurrency coin management, I figured it would be a good idea to share how to create a paper wallet for DigiByte DGB coins. A few weeks back I had written a tutorial titled, Generate Cold Storage Paper Wallets for Ripple XRP Coins with Angular, but we all k...

This course, is the fifth course that I’ve released and the first that hasn’t been on the topic of mobile application developme...

As you’ve probably noticed from the previous few articles, I’ve been doing a lot of development around cryptocurrency wallets using Node.js. Up until now, I’ve only been writing about interacting with different currencies. However, I haven’t discussed how to safely store your wallet information. Whe...

I’m a big fan, and hoarder, of Raspberry Pi devices. If you’ve seen my previous Raspberry Pi tutorials, you’ll know I like using them for hardware and software projects. These microcomputers use very little energy and have decent processors and memory, making them great for a diverse set of projects...

A few weeks back I had written an article titled, Send And Manage DigiByte DGB Coins With Node.js, which had explained how to interact with DigiByte coins via Node.js and the CLI. We saw how to keep track of a wallet, compare against the market value, and send DGB to other wallets. The catch here wa...

So you’ve been doing a lot of research around the blockchain and the various cryptocurrencies. Don’t worry, I’ve been doing a lot of the same research. There is so much in the news and on social media around this subject, it would be a good idea to educate yourself. When it comes to cryptocurrencies...
