Start up local Docker Machine on OSX automatically.

Notice

This script is no longer required with Docker for Mac which includes an option to run Docker at startup and doesn't use docker-machine to administer the local Docker engine.

Requirements

  • Docker Machine + Docker
  • curl
  • A Virtualbox-driven Docker Machine called "default" docker-machine create --driver virtualbox default (this is the default with Docker toolkit).

# And add help text after each target name starting with '\#\#'
help: ## Show this help.
@fgrep -h "##" $(MAKEFILE_LIST) | fgrep -v fgrep | sed -e 's/\\$$//' | sed -e 's/##//'

Latency numbers every programmer should know

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs
