Create An Email Subscription Popup With jQuery

February 7, 2018

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 not everyone appreciates an annoying popup, but it was great for me because I was getting a lot of new email subscribers very quickly.

Since having dropped WordPress, I haven't been able to find a plugin that offered similar functionality to what I had. This inspired me to create my own plugin using jQuery that I could use anywhere, including my Hugo powered blog. We're going to see how to create our own opt-in style popup for collecting email leads.

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 Couchbase and Raspberry Pi IoT Devices.

My first attempt at scanning and analyzing iBeacon data was done with Java and Node.js. The Raspberry Pi devices were using Java, and the data was being offloaded to a Node.js server. The problem with this is that Java is too heavy for the low spec Internet of Things (IoT) devices.

Fast forward to round two of playing with iBeacon devices and a Raspberry Pi. We're going to see how to use Golang to scan for BLE signals and parse the data to determine if they are iBeacon.

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 titled, Generate Cold Storage Paper Wallets for Ripple XRP Coins with Angular.

In this tutorial, we're going to see how to accomplish the same task of generating a cold storage paper wallet with Angular, but this time we'll be doing it for Stellar XLM coins.

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 favorite is Chart.js. It is a vanilla JavaScript library, so including it within a framework can be a little intimidating.

We're going to see how to work with Chart.js within a project that uses the Vue.js JavaScript framework.

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 know Ripple isn't the only technology on the block.

In case you're unfamiliar with paper wallets, they are nothing more than printouts that contain your private and public key information. It is separated from the internet and the paper wallets can be placed in a cold storage location like a locked safe or a bank.

We're going to see how to use JavaScript and the Vue.js framework to generate DigiByte DGB wallet information that includes QR codes for easy scanning.

As you may or may not know, The Polyglot Developer is happy to accept guest contributions from the developer community. To find out more, check out the article titled, Write Guest Articles on The Polyglot Developer Blog. With that said, I've been receiving a lot of questions regarding Markdown, the format in which these blog articles are crafted.

The Polyglot Developer uses Hugo which is similar to Jekyll in the sense that articles are written in Markdown and then built into HTML. Don't worry, Markdown is not bad and you'll see how much more convenient it is than writing in other formats.

We're going to get a quick look at producing content in Markdown so it can be published on the web.
