Create Paper Wallets For Stellar XLM Coins With Angular

February 2, 2018 Nic Raboy

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.

Use Chart.js To Display Attractive Charts In A Vue.js Web Application

January 29, 2018 Nic Raboy

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.

Use Vue.js To Generate Cold Storage Paper Wallets For DigiByte DGB Coins

January 26, 2018 Nic Raboy

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.

January 25, 2018 Nic Raboy

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.

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

Encrypt And Decrypt Data In Node.js With The Crypto Library

January 22, 2018 Nic Raboy

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.

When it comes to storing anything sensitive, whether it be cryptocurrency secrets or something else, you must do so safely and securely. For example, the data must be encrypted at rest and decrypted when used.

We're going to see how to encrypt data with a passphrase using Node.js and decrypt it using that same passphrase when necessary.

Use A Raspberry Pi And A CPU Miner To Mine Altcoins

January 19, 2018 Nic Raboy

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.

With blockchain and cryptocurrencies on the rise, Raspberry Pi devices become great for getting familiar with concepts such as wallets, mining, and synchronized nodes.

We're going to see how to mine Altcoins with a Raspberry Pi and a popular CPU miner.
