  • Introduction To Concurrent Programming: A Beginner's Guide (Publication)
    Concurrency allows programs to deal with a lot of tasks at once. But writing concurrent programs isn't a particularly easy feat. Dealing with constructs such as threads and locks and avoiding issues like race conditions and deadlocks can be quite cumbersome, making concurrent programs difficult to write. In this article, Toptal Freelance Software Engineer Marko Dvečko gives us an overview of some concurrent programming models. He explains how each of these models gives structure to the programs we write and shows how to avoid certain concurrency issues that can come with these models.
