Ruby Concurrency compared

Ruby is used everywhere now. In this talk we will compare Ruby concurrency with Node.js, JVM, Erlang and others.
Ruby supports concurrency but with GIL, it can't run threads parallely. We will explore options available that makes this problem irrelevant.
Node.js doesn’t support concurrency or parallelism. Node.js is single threaded. It runs an event loop which makes non blocking IO possible. We will explore why Node.js fits well to only certain types of problems only
JVM supports native threads and can do parallelism. But in JVM memory is still shared among different objects. We will explore JVM architecture in regards with memory. Where JVM gets it wrong.
Erlang/Elixir achieves concurrency and parallelism with shared nothing, immutable data, first class processes, actor model. We will explore whether this approach is better for solving every kind of problem.
Talk will have deep comparison with all of these platforms in regards with what most real world project need,
