Stakeout Solution

#Stakeout

Congratulations! You are the new elite hacker in a group of villainous ne'er-do-wells.

Luckily this group is more saavy than your last band of ruffians, and they are looking to software (and you) to improve their take. The con man for the team, has gone door-to-door down each street posing as a termite inspector so he could covertly total the valuable goods in each house. Normally the gang would just rob all the valuable homes, but there's a catch! Whenever a house is robbed in this wealthy neighborhood, the police watch it and the neighboring houses for months.

# This is a simple refactoring exercise.
#
# What to do?
#
# 1. Look at the code of the class CorrectAnswerBehavior
# 2. Try to see what it does by running `ruby refactoring_example.rb`
# 3. Record characterisation tests by running `ruby refactoring_example.rb --record`
# 4. Make the code beautiful;)
# 5. You are allowed to modify only the code between markers (REFACTORING START/REFACTORING END).
# 6. Test must pass! You can run them with command `ruby refactoring_example.rb --test`

Crafting Code

Crafting Code

Here's the thing. Computers are nothing more than really fast light switches. On & off millions of times per second. All it cares about is ones & zeroes.

So when it comes to code, and more specifically crafting code, who are we really writing code for?

We're writing it for ourselves, our teammates or our customers - basically other humans. We're using code to express ideas, human ideas in terms of a computer language. As developers, we're tasked with creating sets of instructions to be carried out by our dumb servants to execute these ideas.

If the computer doesn't particularly care about code (other than a clean compile) - what are some of the tools we can use to craft our code for human consumption?

Import/exporting database info from Heroku

Importing/Exporting a Postgres DB from Heroku

In the following scenario, we have the following apps on the Heroku server:

  • Staging Server: staging-stackoverfluff
  • Production Server: stackoverfluff

In addition, each developer has a local development environment.

The goal is to move production data over to the staging server, and also provide production data to each of the developers. Here's what we will do.
