/*
  The "hello world" of neural networks: a simple 3-layer feed-forward
  network that implements an XOR logic gate.

  The first layer is the input layer. It has two neurons a and b, which
  are the two inputs to the XOR gate.

  The middle layer is the hidden layer. This has two neurons h1, h2 that
  will learn what it means to be an XOR gate.

The Open Information Pledge

I believe in the freedom of information, free as in money, and free as in freedom. That this is a fundamental requirement for empowerment.

Ideas

I understand that ideas are not copyrightable. I expect that you understand this too. I expect that we can both regard all ideas discussed to be of Public Domain, as they are.

Implementations

I understand that the implementation of ideas is copyrightable.

Setup Mac OS X

I've done the same process every couple years since 2013 (Mountain Lion, Mavericks, High Sierra, Catalina) and I updated the Gist each time I've done it.

I kinda regret for not using something like Boxen (or anything similar) to automate the process, but TBH I only actually needed to these steps once every couple years...

1. make staging.rb in config/environments - copy production.rb for starters
2. in database.yml , application.yml , cloudinary.yml ... any .yml file , copy the production block and name it staging
2b.   if you are using Resque - make a staging env in initializers/resque.rb
2c. add staging constants for any system-wide URLs 
3. heroku create --remote staging <staging_app_name> --addons [any add ons here].
     create the staging area of the config file
    <staging_app_name> is the part of the url before '.herokuapp.com'  -- muy importante , dont forget 
4.  heroku config:add RACK_ENV=staging RAILS_ENV=staging --remote staging
     set up the rails environment vars
5. git push staging master

eXtreme Go Horse (XGH) Process

Source: http://gohorseprocess.wordpress.com


1. I think therefore it's not XGH.
In XGH you don't think, you do the first thing that comes to your mind. There's not a second option as the first one is faster.

2. There are 3 ways of solving a problem: the right way, the wrong way and the XGH way which is exactly like the wrong one but faster.
XGH is faster than any development process you know (see Axiom 14).
