Project Overview <span>Python-Mastery</span> is an educational project led by renowned Python instructor David Beazley (GitHub ID: dabeaz), aimed at advanced developers. This project focuses on the “internal protocols” and “control semantics” that are widely used but not deeply understood in the Python language, with the goal of helping … Read more
Basics of Coroutines A coroutine is a special software construct that allows a program to pause and resume execution without losing the current execution context. Unlike threads and processes, coroutines run within a single thread and achieve concurrency through a scheduling mechanism, reducing the overhead of context switching and improving program execution efficiency. Coroutines are … Read more
The premise of this article: This is a non-technical article that discusses what coroutines are and the current usage of coroutines, rather than insisting on their necessity. In Linux, coroutine switching is a type of lightweight context switching, which is more efficient than thread switching. Coroutines are a lighter execution unit than threads, typically managed … Read more
Here, I will explain these three concepts from a simple and microcontroller engineer’s perspective, ensuring you understand them at a glance. 🚀 1. Preemptive Scheduler Core: Tasks can be “forcefully interrupted”, and the CPU’s control can be taken away by higher priority tasks at any time. ✔ Features Uses interrupts + priority to control task … Read more
Kafka mentioned that the Android SDK has also been implemented. We attempted to refactor by migrating from OkHttp to Ktor. This is not just a library replacement, but a shift in mindset—from a “callback-based Java style” to a “structured concurrency Kotlin style.” Asynchronous and Concurrency Model of Kotlin/Ktor <span>RealTimeTranscribeClient</span>’s Ktor refactored version demonstrates the Kotlin … Read more
Developers often require a powerful and flexible operating system to support their embedded applications. QuarkTS is an open-source operating system designed to fill the gap between RTOS and bare metal, offering features such as priority cooperative scheduling, time control, inter-task communication, hierarchical state machines, and coroutines, along with C++ and Arduino support, making it an … Read more

Have you ever found yourself trapped in the “callback hell” of asynchronous programming? Have you lost the logic of your code in layers of nested lambdas? C++20 coroutines were born to rescue you from this predicament. 1. What Are We Talking About When We Talk About Asynchronous Programming? Consider a simple requirement: asynchronously read data … Read more
