Question

Is there some way to run 2 threads at the same time?

I want to have my app run its current function and then bring up another thread running another function, that can change variables in the first thread.

Answer 1

http://ruby-doc.org/core/classes/Thread.html

x = 2
Thread.new do
    x = 3
end
x = 4

For true concurrency having more then 2 cores or 2 processors is required – but it may not work if implementation is single-threaded (such as the MRI).
