- To create a private Ethereum network
- To deploy a simple contract to your private Ethereum network
- To interact with a contract on your private Ethereum network
The need for this tutorial arises from outdated Ethereum documentation, resulting in hair-pulling, heartburn, and insomnia.
Isolate your development environment, and your private Ethereum network, from any real Ether you might have. It’s easy to compromise your machine and lose real money if you slip up.
Step 1: Set up a virtual server and install Ethereum command-line tools
Many tutorials guide you through deploying contracts using the Ethereum wallet GUI. I’m using the Go Ethereum client (geth) and encourage others to learn how to use the command line interface (CLI). The better you understand the Ethereum client’s internal workings and the anatomy of a blockchain, the more power to you. It doesn’t matter which hostingservice you…

In 2015, couples spent an average of $32,641 on their wedding.
I don’t know about you, but a price tag like this gives me anxiety. This is one of several reasons we eloped.
Yes, we eloped. It was a lovely, teeny-tiny ceremony in October 2013 in Woodinville, WA.
When it comes up, I get a lot of questions. There are several reasons we made this choice, and I don’t regret it.
If your dream is to have a huge ceremony, that’s fine. However, I bring this up because I’ve had conversations with brides-to-be admitting they never wanted a huge ceremony and feel completely overwhelmed.

I’ve been learning and using React, and I like it’s general approach to building UIs. I really like the unidirectional data flow, though I’m still on the fence about virtual DOM. I get the benefits and really like that it makes testing really easy. However, I am not sold on its being unquestionably better than directly manipulating the DOM or Google’s Incremental DOM. Nevertheless, React, Om, Elm, and others have proven it a viable and fast approach.
I liked many similar attributes of WPF and XAML when I…

As our culture of Christian-y leaders, icons, and unapproachable gurus of influence continue to graduate disciples who are more interested in platform building than bending their knees, we’ve inadvertently, and ironically buried a generation of young hopefuls in a canyon of “well done my good and famous servant” darkness. The good news, however, is that it only takes a flicker of light to conquer a canyon of darkness.
I was recently blessed with one the most encouraging emails I’ve ever received. And it came from one of the wisest, kindest, and youngest people I’ve had the privilege of being connected with on this seven year journey of living by faith, and writing about the results. Jordan S. is a seventeen year old high school student, who has been on quite a journey of her own. As a result, this bright young light has been used by God to not only…
