In our concurrency post, we briefly touched on mutexes. But there's more to locking in Go than just sync.Mutex. Go gives you several synchronization primitives, each designed for a specific access pattern. Use the wrong one and you'll either have a race condition, a deadlock, or unnecessary contention killing …

Python's concurrency story is... interesting. If you've ever Googled "Python multithreading", you've probably run into the GIL debate and come away more confused than when you started. Can Python do concurrency? Yes. Is it straightforward? Not exactly. Python gives you three different concurrency models, each suited for different problems. Pick …

"Don't communicate by sharing memory; share memory by communicating." That's the Go proverb that took me a while to truly understand. When I came from a Python/Django background, concurrency meant threads, locks, and race conditions giving me nightmares. Go changed that for me. Not because concurrency is easy (it's …

If you've been writing Go for any amount of time, you've seen ctx context.Context as the first parameter in almost every function. When I first started with Go, I treated it like a formality - just pass it along and don't think about it. That's fine until your HTTP handler …

Kubernetes is great at managing stateless workloads out of the box. You define a Deployment, it creates Pods, handles rolling updates, and restarts them if they crash. But what about stateful applications like databases? What if you want Kubernetes to understand how to create a PostgreSQL replica, take a backup …

If you've been using Git for a while, you've probably been in this situation: you're deep into working on a feature branch, and suddenly you need to switch to another branch to fix a bug or review a PR. The usual approach is to either git stash your work or …

Have you ever needed to use another Git repository inside your own project? Maybe a shared library, a theme, or a set of configuration files maintained separately? Git submodules let you do exactly that - embed one Git repository inside another while keeping their histories independent. Let's understand how they work …

Infrastructure as Code (IaC) is an approach to managing IT infrastructure in which infrastructure resources are managed as code rather than through manual processes. Terraform is a popular open-source tool for implementing IaC. In this article, we'll explore how to use Terraform to manage infrastructure as code and how it …

AWS Lambda is a serverless computing service that allows you to run your code without provisioning or managing servers. Terraform is a popular tool for infrastructure as code, which allows you to manage your infrastructure as code rather than using manual processes. In this article, we'll explore how to use …
