For today's coding challenge, you'll build a phone number formatter. See if you can do it on the freeCodeCamp mobile app.
A system can appear healthy even when something is going wrong behind the scenes. In this handbook, @irvingpictures shows you how to use Bash and Python for real-world DevOps automation. You'll detect AWS cost spikes, trace service logs, find infrastructure drift, validate secret rotation, and automate canary rollbacks. freecodecamp.org/news/how-to-us…
AI coding agents can work with your code, but they can't always see what's happening in your browser. In this tutorial, Achiya shows you how to connect an AI agent to Safari on macOS using Safari MCP. You'll automate logged-in browser workflows and learn when native browser automation beats headless tools. freecodecamp.org/news/how-to-co…
AI coding agents can build quickly, but unstructured workflows can create fragile software. In this handbook, Qudrat shows you how to build a software factory with Claude Code. You'll create specialized agents, an orchestrator, hooks, and review workflows for safer production development. freecodecamp.org/news/how-to-bu…
Medical images can contain patient identifiers in both their metadata and visible pixels. In this tutorial, Lakshmi shows you how to build an AI-powered de-identification pipeline for clinical research. You'll use MONAI, OCR, and NER to detect and remove sensitive information from DICOM images. freecodecamp.org/news/build-ai-…
AI features often produce shared outputs, which can distort standard user-level A/B tests. In this tutorial, Rudrendu shows you how to use cluster randomization for LLM-based tools in Python. You'll model direct and spillover effects, calculate confidence intervals, and identify where experiments can break down. freecodecamp.org/news/cluster-r…
Flutter developers can now use Dart for both their frontend and their Firebase backend. In this handbook, @atuohaa explains Dart Cloud Functions and the Firebase Admin SDK. You'll learn how to build, test, and deploy functions, share models across your stack, and navigate current limitations. freecodecamp.org/news/how-to-us…
For today's coding challenge, you'll need to return the longest word in a sentence. Seems pretty straightforward, right? Just read the rules first! Check it out on the freeCodeCamp mobile app.
If you want to broaden your skills as a developer, learning about databases and SQL is a good way to go. And this course from Harvard will teach you database and SQL basics to get you started. You'll learn about querying and writing to databases, database design, and how to optimize and scale your DBs, too. freecodecamp.org/news/learn-dat…
If you want to build an AI project that's more than just an API wrapper, this course is for you. In it, Ayush takes you through everything from generating ideas to deploying your app. He also talks about how you can monetize your skills by selling your project idea to clients. freecodecamp.org/news/build-and…
When you're first learning to code, you likely build simple projects like todo apps. And this is great for getting started - but eventually you'll want to build more complex things to showcase your skills. In this tutorial, @sprucekhalifa helps you go from "Hello World" to building real world applications. freecodecamp.org/news/how-to-go…
If you're preparing for technical interviews, you may be working through a bunch of LeetCode problems. And this is helpful, but you should really understand the key concepts behind these DSA problems first. In this visual handbook, Eda goes over the Data Structures & Algorithms concepts you'll need to know - for both LeetCode & job interviews. freecodecamp.org/news/leetcode-…
System design addresses how different parts of a system communicate, manage data, & handle requests. And this course teaches you the key concepts by building a YouTube clone. Along the way you'll incorporate 3 key services: upload, watch, & transcoder. freecodecamp.org/news/learn-hig…
Many devs are using Retrieval Augmented Generation - or RAG - to improve their LLM's capabilities. And in this course, you'll learn RAG fundamentals, along with key model context protocol concepts. The course uses the Python SDK and covers chunking strategies, working with AI agents, and lots more. freecodecamp.org/news/learn-rag…
For today's coding challenge, you'll get the first line of a CSV file, and you'll need to return an array containing the headings. Check it out on the freeCodeCamp mobile app.
Relational databases are used all the time in software development - so as a dev, you should know how they work. In this course, you'll learn relational database design from the ground up. It covers SQL filtering and aggregation, primary, candidate, and super keys, ER diagrams, Normal forms, access control, and more. freecodecamp.org/news/learn-rel…
The Linux operating system powers the majority of the world's servers. So it's a great tool to know. And this course will teach you Linux basics. You'll learn how to manage & troubleshoot a wide range of systems & you'll practice the concepts with labs. freecodecamp.org/news/free-linu…
Becoming a full-stack developer takes a lot of work - and there are lots of skills to learn. To make your journey a little easier, here's 48 hours worth of coursework that'll help get you there. You'll start with basics like HTML & CSS, dive into JavaScript, learn key tools like React and Node.js, and lots more. freecodecamp.org/news/become-a-…
What better way to understand a powerful tool like Claude Code than to build your own version of it? In this handbook, @wagslane walks you through coding your own AI agent. You'll use Python and Gemini and learn about multi-directory projects, how AI tools work under the hood, functional programming, and more. freecodecamp.org/news/build-an-…
With a traditional word processor, you act as the writer, layout designer, and typesetter. LaTeX automates many design mechanics so you can focus on content. In this 41-hour course, you'll learn document structure, math notation, citations, formatting, & more. freecodecamp.org/news/learn-lat…
