#Setting up Nginx on Your Local System ###by Keith Rosenberg

##Step 1 - Homebrew The first thing to do, if you're on a Mac, is to install homebrew from http://mxcl.github.io/homebrew/

The command to type into terminal to install homebrew is:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

## ============================================================================== ##
## function to update a field - basically converts longs to dates for date fields ##
## since json has dates as a long (milliseconds since unix epoch) and geodb wants ##
## a proper date, not a long.
## ============================================================================== ##
def updateValue(row,field_to_update,value):
    outputfield=next((f for f in fields if f.name ==field_to_update),None)  #find the output field

Local SSL websites on macOS Sierra

These instructions will guide you through the process of setting up local, trusted websites on your own computer.

These instructions are intended to be used on macOS Sierra, but they have been known to work in El Capitan, Yosemite, Mavericks, and Mountain Lion.

NOTE: You may substitute the edit command for nano, vim, or whatever the editor of your choice is. Personally, I forward the edit command to Sublime Text:

alias edit="/Applications/Sublime\ Text.app/Contents/SharedSupport/bin/subl"
