Notes and deep dives on software engineering.
Concurrency and parallelism are essential concepts for building efficient software. Learn the difference between concurrency and parallelism, how CPU cores and I/O affect them, and when to use approaches like threads, processes, and asynchronous programming in real-world applications.
Processes and threads are fundamental to how modern software executes. Learn the difference between them, how they share resources, and how concepts like concurrency and parallelism apply to real-world applications, web servers, and background workers.
Synchronous and asynchronous execution are two fundamental ways backend systems handle work. One waits for tasks to finish before moving forward, while the other allows work to continue independently. In this article, we break down the difference with practical backend and Django examples and clarify why asynchronous doesn’t necessarily mean faster.
Webhooks are the backbone of modern application integrations, enabling systems to communicate in real time without constant polling. In this article, you'll learn what webhooks are, how they work, how they differ from traditional APIs, and why they're essential in production systems.
