An example of an AI chatbot conversation about Ruby concurrency concepts and implementation.
What is concurrency in Ruby and how does it work?
Concurrency in Ruby refers to the ability to run multiple tasks simultaneously. It allows for better resource utilization and can improve performance, especially in I/O-bound applications.
Can you explain the difference between threads and processes in Ruby?
Sure! In Ruby, threads are lightweight and share the same memory space, making them faster for context switching. Processes, on the other hand, are heavier and have separate memory spaces, which makes them safer but slower to create.
How do I create a thread in Ruby?
You can create a thread in Ruby using the Thread.new method. For example: Thread.new { puts 'Hello from a thread!' }.
What are some common pitfalls when using concurrency in Ruby?
Common pitfalls include race conditions, deadlocks, and the Global Interpreter Lock (GIL) in MRI Ruby, which can limit true parallel execution.
