Dear God What Am I Doing? Concurrency and Parallel Processing

dieses Thema wird vorgestellt von Adam Hawkins

bei Ruby Usergroup Hamburg - April 2013, gehostet durch Alexander Greim

I gave this talk at RubyConf AU last week. I also gave this same talk at wroc_love.rb I'd like to share with my german friends as well!

Here's a situation we've all be in at one point. We have a program. We want to make that program faster. We know about threads, processes, fibers. Then you start programming and you have no clue what to do. I was there. It sucks. This talk guides you down the rabbit hole and brings out the other side.

Points covered:

  • Threads, Fibers
  • Processes, Forking, Detaching
  • Parellelism vs Concurrency
  • The many many different ways I crashed my computer learning these things
  • Gotchas of each
  • Common ways you shoot yourself in the foot
  • Celluoid

This is a learning and informative talk. It's target at intermediate developers who have ruby experience but never written any multi threaded code.
