In networking, efficient and fair use of shared communication channels is critical to minimizing data collisions and maximizing network performance. Two foundational protocols that manage network access in this context are Carrier Sense Multiple Access with Collision Detection (CSMA/CD) and Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA). These protocols are essential to network performance, particularly in Ethernet (for CSMA/CD) and wireless (for CSMA/CA) environments. Let’s dive into the details of how each protocol works, where it’s used, and its significance in network management. What is CSMA? Carrier Sense Multiple Access (CSMA) is the overarching method that allows devices on…

Mastering runCatching in Kotlin: How to Avoid Coroutine Cancellation Issues

stp2y0 CommentsNewsandroid, basic, coding, community, development, engineering, inclusive, kotlin, programming, software

The runCatching function in Kotlin is a powerful tool that lets you handle exceptions within a block of code while preserving the result. However, when working with coroutines, runCatching can introduce unexpected issues. Because it catches all exceptions, including CancellationException, it can interfere with proper coroutine cancellation. In this article, we’ll explore how runCatching works, its potential pitfalls in coroutines, and how to build custom Result extensions to handle exceptions safely without impacting cancellation. What is runCatching? runCatching is a utility function in Kotlin that executes a block of code and wraps the result in a Result object. If the…
