Ruby's

What is the rule or pattern? Kent said, "I am in terror of not understanding stuff." Learn to feel good about ambiguous situations. "Most of the problems being dealt with by programmers are caused by programmers." Programming at its best is an act of empathy. "Patterns are what you get when you run out of language." Composed Method Double Dispatch coerce Collection management Know your language features Ruby and Smalltalk solve common problems. Shortcut Method Naming patterns Question: I recognize some ideas from SBPP in later works by other authors, e.g. I think “Clean Code” by Robert Martin can be seen as the heir to SBPP. Do you agree? Question: What’s your opinion about the future of Smalltalk? Question: Do you think the latest Smalltalk’s community efforts such as Pharo, Seaside, Amber (previously known as JTalk), etc. could put Smalltalk again in the limelight? Question:  Do you think Smalltalk is worth learning by current programmers? Objects are just an inch under the class. Question: I thought I heard a couple of years ago that you were working on a “Ruby Best Practice Patterns” book with one of the ex-Hashrocket guys. Any truth to this? Any plans for making a ruby version of this book? Question: Any chance of an e-book version of SBPP appearing? Question: How does he balance between learning new or current things versus going back to old (say more than 10 yrs old) publications?

Addressability AJAX Architectural style for building systems Fielding's REST Paper Client/Server Stateless Caching Uniform Interface Code on Demand HATEOAS HTML yields a larger payload than a binary protocol Stateless enables scaling because with all required information in the request it can go to any server prepared to handle it. Cookie-based sessions lean more toward stateless The PUT HTTP verb is misconstrued by Rails PUT does not mean "edit" it's an "upsert" (create or update) PUT is idempotent POST is more generic and non-idempotent Powerful Caching You are supposed to PUT the entire resource rather than the delta.

If Ruby or Rails programmers aren't programming in an object oriented way does it matter? The goal isn't to do OO for OO's sake. Polymorphism Tell, don't ask Encapsulation Case switching on the object's class can be refactored to take advantage of Polymorphism Law of Demeter: Am I allowed to know this? Single Responsibility Principle Ask "What does this object do?" rather than building around the data contained in the object. Presenters (The Presenter Pattern) Steven Kabnik's Post on Object Oriented Programming and the Presenter Pattern in Rails The problem with Helpers In OO, you're allowed to add more Objects (or Classes) Building your models without referencing ActiveRecord Business objects that reference ActiveRecord data access objects Object Thinking The database is the last bastion of non-object oriented thinking Behavior centric vs data centric design The impedance mismatch between the database and the object oriented designs Inheritance Object Oriented Design centers around maintainability and complexity Don't use generators Create classes and evolve them into models as you need the persistence Rather than asking for data, tell a class to do something for you Three small things to watch out for: Switch/case on class Arrays and hashes or arrays of hashes of arrays (Primitive Obsession) Subclassing Array or Hash forwardable delegate Don't inherit from String Enumerable module Rake's FileList Skinny Controllers Is REST simply a way of pulling the impedance mismatch from the database all the way up to URL's?
