Building software with AI is not all about prompting. Adding rule-based checks and tests makes results safer and more reliable. In this in-depth tutorial, @sumit_analyzen teaches you how to use a practical coding loop technique to get better results from AI. freecodecamp.org/news/how-to-gu…

Proper documentation makes your REST API usable. Without proper docs, other devs won't know how to work with your API. Here, Dominic shows you how to generate an OpenAPI specification and use Scalar to serve them from your Node.js app. freecodecamp.org/news/rest-api-…

Getting a web dev job today is more competitive than ever. You need more than just a portfolio to land a job. Here, Ilyas goes over strategy, skills prep, applications, interviews, and more so you make smarter decisions while looking for your next role. freecodecamp.org/news/the-ultim…

For today's coding challenge, you'll get an integer greater than 1. Your task is to return its prime factorization as an array of numbers in ascending order. See if you can solve it on the freeCodeCamp mobile app.

RAG can fail in various ways even when it finds the right chunk. The problem is often context budgeting: the chunk was found, but it didn't fit into the final prompt. In this guide, Sviatoslav shows how to handle small context windows with document summaries, chunk summaries, raw chunks, and traceable prompt budgets. freecodecamp.org/news/how-to-ha…

Typed error handling is useful, but rewriting the same Result pattern in every Dart project can get old. In this guide, @devseyi explains how DartExceptor works, a lightweight Dart 3 package for visible, compiler-friendly failures. You'll use Trace, Ok, Err, split, map, mapError, and bind to handle errors across clean architecture layers. freecodecamp.org/news/how-to-us…

Some scheduled jobs don't need a separate worker, crontab, or Kubernetes CronJob. If the work is already SQL, PostgreSQL can run it directly with pg_cron. In this guide, @Iyiola_dev_ shows you how to schedule cleanup jobs, refresh materialized views, build rollup tables, manage permissions, and more. freecodecamp.org/news/how-to-sc…

Fine-tuning one small language model is manageable, but a whole fleet can get messy. In this guide, Tejas shows you how to prevent model rot across domain-specific SLMs. You'll build a model registry, route versions through a gateway, use semantic versioning, and deploy updates to edge devices with manifest-based delivery. freecodecamp.org/news/how-to-bu…

Not every React performance issue needs useCallback or useMemo. Sometimes the better fix is moving state and logic closer to where they're used. In this guide, @_jongbo explains how to refactor a search page, avoid unnecessary memoization, prevent unstable-reference bugs, and use React DevTools before optimizing. freecodecamp.org/news/how-to-av…

AI agents don't always fail by crashing. Sometimes they fail by running forever. In this guide, @dannwaneri teaches you how to build a production-safe agent loop in Python. You'll define exit conditions, enforce token and turn limits, write an append-only SQLite audit trail, and add human review before downstream systems receive output. freecodecamp.org/news/how-to-bu…

Hey my weekend warriors freeCodeCamp has some banger (pretty advanced) software engineering tutorials in this week's 5 links worth your time. Check it.

For today's coding challenge, you'll get a rental timestamp, a return timestamp, and a rental tier. You'll need to return the cost of the rental (including any late fees) based on certain rules. Check it out on the freeCodeCamp mobile app.

When you're shipping features, understanding what they cost is often critical. To improve your financial literacy here, this FinOps roadmap takes you from cloud-cost awareness to true leadership. Ayobami covers AWS bill analysis, tagging, right-sizing, Savings Plans, cleanup automation, dashboards, chargeback models, and lots more. freecodecamp.org/news/the-2026-…

Your CI/CD pipeline doesn't have to just fail and wait for someone to investigate. In this course, Farzeen shows how to build a self-healing DevOps workflow with GitHub, OpenAI, and n8n. You'll analyze failing logs, generate patches, open pull requests, secure secrets, trigger webhooks, and notify your team automatically. freecodecamp.org/news/build-a-s…

Cloud text-to-speech is great until every spoken sentence adds cost, latency, and third-party data exposure. In this guide, @djibril_mg shows you how to run private TTS right on mobile hardware with QVAC. You'll build a React Native app that loads a Supertonic model, generates speech offline, wraps PCM samples into WAV files, and plays them with a waveform UI. freecodecamp.org/news/how-to-ru…

When you're building a website, your tech stack matters...but it's not the whole story. In this article, @manishmshiva explains what really makes websites succeed in 2026. You'll learn why performance, hosting, structured data, content quality, UX, and AI search visibility often matter more than framework choice. freecodecamp.org/news/building-…

Learning Kubernetes isn't all about memorizing commands. It really clicks when you start building like a platform engineer. In this course, you'll learn everything from core concepts to advanced industry standards like using Prometheus & Grafana for observability. freecodecamp.org/news/master-ku…

The future of software is code that reasons. And learning Python is your first step. In this video course, you'll learn Python fundamentals, NumPy, Pandas, SQL, Flask, LLMs, and everything else you need to dive into AI Agent development. freecodecamp.org/news/learn-pyt…

For today's coding challenge, you'll get an array representing some movies in your streaming service's cart, along with a string representing your subscription tier. You'll need to return the total cost of the movies. Check it out on the freeCodeCamp mobile app.

Building a game is a great way to improve your programming skills. It makes you consider things like performance, user input, and structure while getting creative with your problem-solving. In this guide, @manishmshiva walks you through some of the key skills game dev helps you sharpen. freecodecamp.org/news/improve-y…
