eXtreme Go Horse (XGH) Process

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).

A simple test to load a series of web pages in Chrome on MacOS repeatedly until the battery runs out.
on run
set imessage_id to "" -- leave blank to skip sending periodic iMessage progress updates, put your iMessage ID here to get updates as the script runs
set delay_seconds to 5 -- Don't set to 0, it runs too fast. 0.75 is a good setting for "go fast".
set computer_name to do shell script "scutil --get ComputerName"
set os_version to do shell script "sw_vers -productVersion"
set os_build to do shell script "sw_vers -buildVersion"
set _uptime to do shell script "uptime"

Moving to ES6 from CoffeeScript

Moving to ES6 from CoffeeScript

I fell in love with CoffeeScript a couple of years ago. Javascript has always seemed something of an interesting curiosity to me and I was happy to see the meteoric rise of Node.js, but coming from a background of Python I really preferred a cleaner syntax.

In any fast moving community it is inevitable that things will change, and so today we see a big shift toward ES6, the new version of Javascript. It incorporates a handful of the nicer features from CoffeeScript and is usable today through tools like Babel. Here are some of my thoughts and issues on moving away from CoffeeScript in favor of ES6.

While reading I suggest keeping open a tab to Babel's learning ES6 page. The examples there are great.

Punctuation

Holy punctuation, Batman! Say goodbye to your whitespace and hello to parenthesis, curly braces, and semicolons again. Even with the advanced ES6 syntax you'll find yourself writing a lot more punctuatio

# In your test_helper.rb
class ActiveRecord::Base
mattr_accessor :shared_connection
@@shared_connection = nil
def self.connection
@@shared_connection || retrieve_connection
end
end
