I come from a hardware and embedded background, where most of my code has been sequential and concurrency is handled fairly explicitly. High-level asynchronous programming has been much…
My local Chrome fleet worked well until several target sites began applying stricter detection and additional checks. The same Playwright scripts now lose about half of their parallel…
My local Chrome fleet worked well until several target sites began applying stricter fingerprinting and automated-traffic checks. The same Playwright scripts now lose roughly half of their parallel…
I come from a mostly hardware and embedded background, where code generally follows a clear sequential flow. High-level asynchronous programming has been difficult for me to understand, especially…
I'm learning Java and trying to understand how Thread.sleep(1000) works in this loop. The code updates a progress bar, pauses for one second, and catches InterruptedException if the…
I'm learning Java and trying to understand what happens when I call Thread.sleep(). In this loop, the progress bar is updated and then the current thread pauses for…
I have about 1–2 years of experience with PHP and Laravel, and I'm planning to move into Go to expand my career options. For people who use Go…
I have a basic C11 thread pool that works well for fire-and-forget jobs, but I now want callers to wait for a particular task to finish. Tasks are…
I have a basic multithreaded task pool in C11 that works well for fire-and-forget jobs. I now want to add a function that waits for one particular task…
I'm new to web development and still getting used to how server-side applications handle persistence. For a small amount of data—such as whether a user prefers chocolate or…
I am trying to optimize a C++20 program by splitting work across 12 threads. The single-threaded version works, but after adding threads and several std::barrier synchronization points, the…
I'm writing a Bash script that processes a list of tasks in parallel, with a fixed limit such as four jobs at once. I want to implement this…
I am trying to parallelize a C++20 program that computes Grundy values for Grundy's game. The sequential version works, but after adding twelve worker threads and several std::barrier…
I understand the basic story that Java source is compiled into bytecode and that the JVM eventually executes or JIT-compiles that bytecode into machine instructions. Beyond that, I…
I'm diving into the concepts of concurrency and parallelism, but I'm a bit confused about how they're related. Originally, I thought concurrency meant that tasks only seem to…
I'm trying to wrap my head around the internals of Python, specifically the Global Interpreter Lock (GIL). Is it true that each process has its own GIL, or…
I'm trying to figure out how to cancel task1 from within task2 using Python's asyncio module. I attempted to call t1.cancel(), but it doesn't seem to stop task1…
I'm really interested in diving deep into high-performance web development, especially on the backend. I want to learn how to achieve higher requests per second, reduce CPU usage,…
Hey folks! I've been diving into async programming in JavaScript and I'm finding concurrency and race conditions to be pretty challenging. I'm using Promises, async/await, and even tools…
I'm curious if Go is a solid option for building a web backend. I've worked with frameworks like Ruby on Rails and Django before—has anyone switched to using…
