What are some real-world examples of race conditions?

Race conditions occur when multiple processes access shared resources concurrently, leading to unpredictable outcomes. A classic example is the ATM withdrawal scenario, where two users attempt to withdraw money simultaneously, potentially causing one to overdraw their account.

Can you explain how this affects software development?

In software development, race conditions can lead to bugs that are hard to reproduce. They can cause data corruption, crashes, or security vulnerabilities, making it crucial to implement proper synchronization mechanisms.

What are some strategies to prevent race conditions?

To prevent race conditions, developers can use techniques like locking, semaphores, and atomic operations. These methods ensure that only one process can access a resource at a time.

Are there any famous incidents caused by race conditions?

Yes, one notable incident is the Therac-25 radiation therapy machine, which had a race condition in its software, leading to patients receiving lethal doses of radiation.
