How To Come Up With An App Idea And Execute In Development

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 execute on them for a successful release. Being a solid developer is one thing, but having a solid plan is another.

I’m going to share my process so you can be more successful with your web and mobile application releases.

Simple User Login in a Vue.js Web Application

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 implement a simple login form in a web application that uses the Vue.js JavaScript framework.

Access And Change Parent Variables From A Child Component With Vue.js

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 the child component. Take for example an application that has authentication. The parent component might manage the authentication state while the child component might be a login form, secure content, or something else. When logging in, you might need to change the authentication state of the parent. This is just one of many possible examples where the child and parent need to interact.

We’re going to see how to interact with a parent component from a child component in an application created with the Vue.js JavaScript framework.

Manage Multiple Authors On A Static Blog Created With Hugo

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 article, this site is always accepting guest contributions for technical content. There have been several tutorials contributed, but when it comes to credit, I want these tutorials to show under the authors name, not my name just because I’m the owner of the blog.

We’re going to see how to work with data templates in Hugo to create and use different authors for different articles.

Create A Bitcoin Hardware Wallet With Golang And A Raspberry Pi Zero

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 several Raspberry Pi Zero and thought it would be a perfect opportunity to take what I know about Raspberry Pi and Golang to create a wallet for a fraction of the price as the industry leading wallets.

We’re going to see how to create a hardware wallet, which I’m calling the Open Ledger Micro, using Golang and a Raspberry Pi Zero.

Create And Sign Bitcoin Transactions With Golang

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 anything.

The next step in making Bitcoin and other cryptocurrencies useful is to be able to transfer or send them to other people. Sending Bitcoin is part of a process known as creating and broadcasting a transaction.

While we won’t be actually broadcasting a transaction in this tutorial, we’re going to figure out how to create an unsigned transaction, then sign it, using the Go programming language and some popular Bitcoin packages.

Use Node.js And A Raspberry Pi Zero W To Scan For BLE iBeacon Devices

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 (IoT) devices like the Raspberry Pi Zero W, and Golang isn’t the only great language around. I, like many others, do a lot of Node.js development as well.

We’re going to see how to scan for BLE iBeacon devices using Node.js and the popular Node.js BLE (Noble) library.
