BOSH command line interface cheatsheet

Introduction

Bosh is a powerful tool to install and manage your Cloud Virtual Machine workloads (VMs), referred to as “deployments”. You can find docs on //bosh.io/docs. Consider using bosh create-env tool to install to a Cloud of your choice a new Bosh Director.

Bosh uses a CPI (Cloud Provider Interface) to talk to the underlying IaaS/Cloud and manage Cloud workloads, just like a computer uses a driver to talk to a printer. CPIs are very similar to the Infrastructure Cloud Providers later implemented in the ClusterAPI technology, but Bosh abstractions apply to any scope of workloads where ClusterAPI is very restrictive, and Bosh concepts map the problem space better than ClusterAPI, reaching better efficiency in the convergence loop towards the expected (healthy) state of workloads.

Director, Stemcell, Release, Deployment, Instance, are words that have a very specific meaning in Bosh context, so we capitalize them here.

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.

What is Relay?

Relay is a new framework from Facebook that provides data-fetching functionality for React applications. It was announced at React.js Conf (January 2015).

App configuration in environment variables: for and against

For (some of these as per the 12 factor principles) 

1) they are are easy to change between deploys without changing any code

2) unlike config files, there is little chance of them being checked
into the code repo accidentally

3) unlike custom config files, or other config mechanisms such as Java

I'm having trouble understanding the benefit of require.js. Can you help me out? I imagine other developers have a similar interest.

From Require.js - Why AMD:

The AMD format comes from wanting a module format that was better than today's "write a bunch of script tags with implicit dependencies that you have to manually order"

I don't quite understand why this methodology is so bad. The difficult part is that you have to manually order dependencies. But the benefit is that you don't have an additional layer of abstraction.
