Lightning Network User Use Cases

The Lightning Network is a layer 2 payment network built on top of Bitcoin (and other cryptocurrencies).

It is denominated in the currency of the blockhain upon which it sits (first and primarily Bitcoin), and disputes are settled entirely by the base blockchain (Bitcoin).

Like Bitcoin, it is decentralized. Ultimately, the utility, speed and cost of the network will be defined by

1. Install Homebrew http://brew.sh/

2. Install Jack (route audio tool) http://jackaudio.org/. Current stable version from official website doesn't work with
MacOS Sierra (I use 10.12.3) so you need to download beta version from there https://yadi.sk/d/JwT10b7v3Dm5yy.
After installing reboot your computer.

3. Install Darkice (audio streamer) via brew.

The Complete Guide to Nested Forms in Phoenix

I recently spent some time dealing with nested forms in Phoenix. Nested forms are great when you want to create multiple database records in a single transaction and associate them with each other. I am new to Phoenix and really struggled to find any resources that helped me with my specific problem. I decided to document what I learned in the process in hopes of helping others that are new to Elixir and Phoenix.

Here is my attempt at a one stop shop to learn everything you will need to know about nested forms. If you would like to view the GitHub repo you can check it out here.

Thanks to Heartbeat and Jose for excellent blog posts on nested forms. Also shoutout to Josh for showing me some examples at Ruby

The experience of using Node.JS with TypeScript, ts-node, and ESM is horrible.

There are countless guides of how to integrate them, but none of them seem to work.

Here's what worked for me.

Just add the following files and run npm run dev. You'll be good to go!
