🥇 Instead of sending Ether, use the withdrawal pattern
🥈 If you really need to send Ether, use a safe wrapper like OpenZeppelin's Address.sendValue(addr, amount)
🥉 If you really need to send Ether without dependencies, use (bool success, ) = addr.call{value: amount}("")

You have a repository, call it alice/repo. You would like to transfer it to the user bob, so it will become bob/repo.
However, you make heavy use of the GitHub Pages feature, so that people are often accessing https://alice.github.io/repo/. GitHub will helpfully redirect all of your repository stuff hosted on github.com after the move, but will not redirect the GitHub Pages hosted on github.io.
This is a quick-and-dirty guide to setting up a Raspberry Pi as a "router on a stick" to PrivateInternetAccess VPN.
Install Raspbian Jessie (2016-05-27-raspbian-jessie.img) to your Pi's sdcard.
Use the Raspberry Pi Configuration tool or sudo raspi-config to:

Hi Nicholas,
I saw you tweet about JSX yesterday. It seemed like the discussion devolved pretty quickly but I wanted to share our experience over the last year. I understand your concerns. I've made similar remarks about JSX. When we started using it Planning Center, I led the charge to write React without it. I don't imagine I'd have much to say that you haven't considered but, if it's helpful, here's a pattern that changed my opinion:
The idea that "React is the V in MVC" is disingenuous. It's a good pitch but, for many of us, it feels like in invitation to repeat our history of coupled views. In practice, React is the V and the C. Dan Abramov describes the division as Smart and Dumb Components. At our office, we call them stateless and container components (view-controllers if we're Flux). The idea is pretty simple: components can't
| import { Component } from "React"; | |
| export var Enhance = ComposedComponent => class extends Component { | |
| constructor() { | |
| this.state = { data: null }; | |
| } | |
| componentDidMount() { | |
| this.setState({ data: 'Hello' }); | |
| } | |
| render() { |
