This is a guide for Scala and Java development on Windows, using Windows Subsystem for Linux, although a bunch of it is applicable to a VirtualBox / Vagrant / Docker subsystem environment. This is not complete, but is intended to be as step by step as possible.
Read the entire Decent Security guide, and follow the instructions, especially:
Upon completion you will have a sane, productive Haskell environment adhering to best practices.

2015-01-29 Unofficial Relay FAQ
Compilation of questions and answers about Relay from React.js Conf.
Disclaimer: I work on Relay at Facebook. Relay is a complex system on which we're iterating aggressively. I'll do my best here to provide accurate, useful answers, but the details are subject to change. I may also be wrong. Feedback and additional questions are welcome.
Relay is a new framework from Facebook that provides data-fetching functionality for React applications. It was announced at React.js Conf (January 2015).

Attic is the holy grail of backups:
RHEL/CentOS don't have native Python 3 packages. Attic requires Python 3.2+.
We'll install Python 3 using IUS repositories here: https://iuscommunity.org/pages/About.html
Always better to use managed than unmanaged installations, which are hard to manage later on.
