Notes From "Practical Object-Oriented Design In Ruby" by Sandi Metz
View poodir-notes.md

Chapter 1 - Object Oriented Design

The purpose of design is to allow you to do design later, and it's primary goal is to reduce the cost of change.

SOLID Design:

  • Single Responsibility Principle: a class should have only a single responsibility
  • Open-Closed Principle: Software entities should be open for extension, but closed for modification (inherit instead of modifying existing classes).
  • Liskov Substitution: Objects in a program should be replaceable with instances of their subtypes without altering the correctness of that program.
  • Interface Segregation: Many client-specific interfaces are better than one general-purpose interface.

// Just before switching jobs:
// Add one of these.

// This started as a tweet with a joke of "C++ pro-tip: #define private public",
// and then it quickly escalated into more and more evil suggestions.
// I've tried to capture interesting suggestions here.

Using strace and lsof
View gist:1384523

Using strace and lsof to debug blocked processes

You can use strace on a specific pid to figure out what a specific process is doing, e.g.:

strace -fp <pid>

You might see something like:

select(9, [3 5 8], [], [], {0, 999999})   = 0 (Timeout)

Lambda: standard

# Creating a lambda
l = lambda { |name| "Hi #{name}!" }

# Executing the lambda
l.call("foo") # => Hi foo!
