Ruby Book Club Podcast

In which Nadia and Saron wrap up the Ruby Book Club podcast! Hear why the show has come to an end, what Nadia and Saron have learnt over the last 2 years, and what they're planning to read next.

Nadia and Saron finish Chapter 8. They discuss the proc object, changing local variables after lambda has already been called, and calling lambda more than once in the same scope.

Nadia and Saron continue with Chapter 8. They look at lambdas and procs, including treating functions as first-class citizens, stack vs. heap memory, and how Ruby saves a string value.

Nadia and Saron start Chapter 8. They discuss blocks! We learn about closures and which is faster: a 'while' loop or passing a block to 'each'.

Nadia and Saron finish Chapter 7! They discuss how Ruby implements hash functions and hash optimisation in Ruby 2.0.

Nadia and Saron start Chapter 7. They talk about hash tables, including how we save and retrieve values from them, hash collisions, and rehashing.

Nadia and Saron discuss constant lookup and finish off Chapter 6.

Nadia and Saron discuss Module#prepend and dive deeper into how modules and submodules behave.

Nadia and Saron discuss the global and inline method caches, including modules into classes and one another.

Nadia and Saron start Chapter 6! They discuss how Ruby implements modules and the method lookup algorithm.

Nadia and Saron continue Chapter 5. They look at the RClass structure some more and look at where Ruby saves class methods. Then they review key takeaways from Chapter 5.

Nadia and Saron continue Chapter 5. They look at the RClass structure, including inheritance, class instance variables vs. class variables, getting and setting class variables, and constants.

Nadia and Saron finish continue Chapter 5, where they delve a bit deeper into the internal structure of a Ruby class, discuss generic objects, look at objects that are so simple that they don’t need a structure, the mystery of instance variables on generic objects, and more.

Nadia and Saron finish off Chapter 4 and start Chapter 5. They look at how Ruby implements keyword arguments and start to look at the inside of a Ruby object, focusing on 'klass' and 'ivptr'.

Nadia and Saron continue with Chapter 4, looking at how Ruby implements for loops internally, the send instruction, calling normal Ruby methods, and calling built-in Ruby methods.

Nadia and Saron get stuck into Chapter 4. They look at how Ruby executes if statements, how Ruby jumps from one scope to another, and catch tables.

Nadia and Saron pick up where they left off in Chapter 3 and dive deeper into special variables, summarize what they've learnt in chapter 3, and look ahead to Chapter 4.

Nadia and Saron take a break from the book to look at some helpful notes that Pat Shaughnessy put together for them based on questions they had in Episodes 7 and 8.

Nadia and Saron look at local and dynamic access of variables in chapter 3 of Ruby Under A Microscope.

Nadia and Saron look at executing a call to a block, paying particular attention to control frame structures, how YARV instructions are constructed, and benchmarking Ruby 2.0 and 1.9 against Ruby 1.8.
