A step-by-step guide to containerising a FastAPI application with Docker and deploying it to the cloud for consistent, production-ready delivery. Modern applications rarely live in isolation. They move between laptops, staging servers, and production environments. Each environment has its own quirks, missing libraries, or slightly different configurations. This is where many “works on my machine” […]
In the world of big data, performance isn’t just about bigger clusters – it’s about smarter code. Spark is deceptively simple to write but notoriously difficult to optimize, because what you write isn’t what Spark executes. Between your transformations and actual computation lies an invisible translation layer – the logical plan – that determines whether […]
Feature flags are powerful tools that let you control which features are visible to users without deploying new code. They enable gradual rollouts, A/B testing, and instant feature toggles, which are all essential for modern software development. In this article, we’ll build a real, production-ready feature flag system, not just a simple boolean toggle. Specifically, […]
Your UI doesn’t “randomly” refuse to update. In most cases, it’s rendering cached data, which is data that was saved somewhere so the app doesn’t have to do the same work again. Caching is great for performance, but it becomes a pain when you don’t realize which layer is reusing old data. If you’ve ever […]
Harvard University’s CS50 is one of the most popular beginner computer science courses in the world. We just released the entire 25-hour CS50 course on the freeCodeCamp.org YouTube channel. This is the most recent version updated for 2026, with an all-new section about the impact of artificial intelligence on computer science. David J. Malan is […]
Today Quincy Larson interviews Tapas Adhikari. He’s a software engineer who runs a firm of 20 developers who build projects for companies around the world. He’s also a prolific teacher, having written 300 programming tutorials – including 47 for freeCodeCamp – and runs a popular English and Bangla-language YouTube channels. We talk about: The changing […]
Prioritization in product management is hardly about what metric takes precedence over the other. Of all the roles a product manager plays, one of the most difficult is deciding what to work on next. Why? Because everything feels urgent. Engineers want to fix technical debt, users want improvements, stakeholders have more opinions than practical solutions, […]
Relational databases are used in many different types of software. We just posted a course on the freeCodeCamp.org YouTube channel that will help you learn relational database design from the ground up. This course covers SQL fundamentals, entity-relationship modeling, normalization (1NF through BCNF), data types and constraints, indexing strategies, and query optimization. This course is […]
Creating complex objects can get messy. You’ve probably written constructors with too many parameters, struggled with optional arguments, or created objects that require multiple setup steps. The builder pattern solves these problems by separating object construction from representation. In this tutorial, I’ll show you how to implement the builder pattern in Python. I’ll also explain […]
