Docker Machine OSX Autostart

This is a simple launchd config that will start your default docker-machine on startup. You can customize the machine that is started by updating lines 11 and 16 with the correct machine name.

Install

1. Copy the file com.docker.machine.default.plist below to ~/Library/LaunchAgents/com.docker.machine.default.plist.
2. Run the following in a terminal: launchctl load ~/Library/LaunchAgents/com.docker.machine.default.plist
3. Profit!

Cryptographic Best Practices

Putting cryptographic primitives together is a lot like putting a jigsaw puzzle together, where all the pieces are cut exactly the same way, but there is only one correct solution. Thankfully, there are some projects out there that are working hard to make sure developers are getting it right.

The following advice comes from years of research from leading security researchers, developers, and cryptographers. This Gist was [forked from Thomas Ptacek's Gist][1] to be more readable. Additions have been added from

// NOTE: this adds a filename and line number to winston's output
// Example output: 'info (routes/index.js:34) GET 200 /index'

var winston = require('winston')
var path = require('path')
var PROJECT_ROOT = path.join(__dirname, '..')

var logger = new winston.logger({ ... })

// this allows winston to handle output from express' morgan middleware
