Ruby Design Patterns - Methods over Attributes

Overview

The objective of this article is to highlight the subtle differences between using class attributes and class methods in Ruby. Both offer a valid way to manipulate the state of an instance of a class. Things can get increasingly complex, hard to test and hard to maintain as more instance variables are introduced. Beginner and intermediate Rubyists often miss this subtle but important point which can introduce bugs that may be hard to fix in their native habitat.

The reasons I prefer to use methods over instance variables:

• Increases predictability of method calls
• Increases predictability when testing

// Sometimes I have a promise chain that returns out of a promise before 
// the the execution is actually completed. Maybe i'm not returning correctly?
// Anyway, might be a common problem for a newb, like me.
// here is a way to add a delay in the promise chain to wait for the previous
// promise to complete. This is NOT best practice, but maybe it can be used as
// a troubleshooting tool.

1. Convert our ".jks" file to ".p12" (PKCS12 key store format):
 
keytool -importkeystore -srckeystore oldkeystore.jks -destkeystore newkeystore.p12 -deststoretype PKCS12
 
1.1. List new keystore file contents:
 
keytool -deststoretype PKCS12 -keystore newkeystore.p12 -list
 
2. Extract pem (certificate) from ".p12" keysotre file:

TypeError: Cannot read property 'getTableName' of undefined or foo.bar is not a function

I've had this error on numerous occasions. Here are a few things to look for:

• Check that the table name that is included in the query is spelled correctly, check that is it defined correctly (for sequelize).
• If you are running tests and using Mockery, check that Mockery is setup correctly. Try removing Mockery and running the test.
• Check that if you are trying to stub with Sinon, that Mockery isn't ALSO trying to stub out the same object.
• Example of stubbing with Sinon instead of Mockery: https://gist.github.com/todgru/e439373af2488eefc30ae8bd1fe3864a

#git Branch

Bits about gits

(freakin awesome http://git-scm.com/book/en/Git-Branching-Basic-Branching-and-Merging)

Also, see JadedEvan's gist about branching. In particular, 'Create a new branch and have it track remote commits'

To create a new branch and switch to that branch:

$ git checkout -b my_new_branch

then ran diskutil list to find the identifier

/dev/disk2s1 in my case
