• Introduction
• Syntax (https://gist.github.com/y8/218075c437b13b8dd3f0)

• Short on OOP theory
  • Objects, properties
  • Encapsulation, polymorphism
  • Classes, inheritance

• Object Model
  • Variables: lvar, ivar, cvar, gvar, const
  • Object, Module, Class
  • Everything is a pointer to object, memory management, GC, RValue & inline objects
  • Inheritance, Mixins, Method Lookup
  • Eigenclass, ruby great mystery
  • Scopes, lexial, logica, execution. Opening/Closing/Inheritance (scope gates), role of self
  • Blocks: it’s an argument
  • Methods: definition/removal, signature, scope
  • Closures, Continuations

• Execution
  • Exceptions
  • trow, catch, callcc
  • Operator precedence
  • eval, SAFE_MODE
  • Scope evaluation: class_eval, instance_eval
  • require, load, autoload
  • Hooks: const_missing, method_missing, inherited
  • ENV, ARGV

• Built-in types
  • Integer, Float, Bignum
  • String, Symbol
  • Array, Enumerable, lazy loading, decomposition
  • Hash
  • Regexp
  • IO: File, UDP/TCP/UNIX Sockets

• Parallelism
  • Main problems: race conditions, deadlock, livelock, simultaneous access, data integrity
  • IPC, fork, pipe
  • Thread, Mutex, Queues
  • Fiber
  • DRB (???)
  • Reactors (EventMachine, ???)
  • Actors (celluloid, ruby-concurrency)

• Tools
  • rake
  • rubygems (including internal mechanisms)
  • bundler
  • rvm, chruby, rbenv
  • extensions, ffi

• Testing
  • rspec, minispec, mspec
  • test-unit, minitest

• Debugging, profiling, benchmarking
  • pry, ruby-debug, debug2, buybug
  • dtrace
  • benchmark, benchmark-ips
  • lineprof, ruby-prof
  • rubyben.ch

• Other implementations around
  • rbx, live metrics, console, JIT
  • jruby, Truffle, Graal, Total Awesomness
  • mruby, embedded, ARM demo

• Practice
  • OOP
    • Simple ORM (or maybe proper SMPP driver?)
      • testing
      • profiling
  • Tools
    • making a gem
    • rake tasks
    • simple c extension
  • Parallelism
    • fork, ipc — small server
    • threads — blocking IO (driver to server?)
    • fibers – ???
    • EM — messaging
    • DRB — ???
    • Actors — simple in-memory game server

• Bonus Track
  • VM basics, AOT, JIT, opmiziations
