This is the most popular freeCodeCamp course we've published all month. And we published 2 FREE banger books this week, too. Hit 'em.

Kotlin is sooo much easier to program in than Java, and it's compatible with Android and the JVM. freeCodeCamp just dropped a 10 hour course to teach you how to use it. Check it!

I've started publishing my book reviews on the freeCodeCamp forum. My first one: Slaying the Dragon, a history of TSR and D&D. 🐉⚔️

Be VERY careful with algo trading. But yes, the python app you build in this course really does work. And freeCodeCamp published some banger books this week, too.

I had a blast making this documentary in Hong Kong. 40 minute watch. And fCC published some free courses and books this week, too. Enjoy.

freeCodeCamp commissioned this art by @readyplayermari with characters from our English curriculum. What do you all think? Is it campy enough for you?

BTW freeCodeCamp has a PLATINUM transparency rating from Candid, which ranks charities by transparency. freeCodeCamp is a simple charity with a simple mission: create FREE learning resources for EVERYONE. Y'all can donate knowing we'll do just that. 🏕️donate.freecodecamp.org

A massive thanks to all y'all who attended @CommitYourCode last week. freeCodeCamp is proud to be among the 3 charities selected to receive donations from ticket sales. We'll put this $6,407.70 toward building more FREE open source learning resources for everyone. 🫶 🏕️

fCC is keeping the FREE books and courses rolling hot off the press. Good pickups this week.

A lot of heavy engineering courses in this week's roundup. Keep pushing forward with your skills! 🏕️

A camper solved all 365 days of the freeCodeCamp daily coding challenge without AI assistance, wrote about their journey, and shared their solution repo. 🥳 Some serious consistency and work ethic on display here.💪 Forum thread: forum.freecodecamp.org/t/sol…

Learn DSA through sweet graphical explainers (free 1 hour course)

Only 10 days until Commit Your Code in Dallas! Tickets are only $40. Join me and hang out with inspiring devs. commityourcode.com/

This weekend learn how to do reinforcement learning in C. Because why not. FREE 2 hour course freeCodeCamp just dropped this week, and 4 other resources you should check. 1. freeCodeCamp just published a course that will teach you how to code your own reinforcement learning framework from scratch in pure C. You'll implement the systems that help your agent observe its environment, choose actions, receive rewards, and improve through experience. I'd normally attempt this in Python, but considering that Python itself is written in C, this'll give you a much deeper understanding of what's happening under the hood. (2 hour YouTube course): freecodecamp.org/news/buildi… 2. The world runs on crusty old legacy codebases. Some of these were elegantly written by devs who knew what they were doing. But a lot of it is spaghetti that no one had the guts to touch. Until now. This new freeCodeCamp guide will show you how to use AI tools to understand legacy codebases, document their behavior, and modernize them incrementally. You'll also learn where human review and automated tests fit into the process. (25 minute read): freecodecamp.org/news/modern… 3. Learn how to roll your own multi-agent system that reviews pull requests for you. You'll learn how to slice n' dice the review process for your new team of specialized agents. You've got a security expert agent, one focused on code quality, testing, documentation. You'll voltron their powers using the fan-out and fan-in pattern. No course would be complete without an exploration of AI failure modes, database design, and orchestration tools. (3 hour YouTube course): freecodecamp.org/news/learn-… 4. Wanna build your own Discord bot using Python? This handbook has got you covered. Everything from registering your bot, configuring its permissions, connecting it to your custom Python scripts, responding to messages, and other events. You'll also learn how to lock down sensitive credentials like your bot token. (full length handbook): freecodecamp.org/news/how-to… 5. Finally, learn how to build your own multi-agent financial research system using the open source LangChain Deep Agents harness. You'll create specialized agents that can investigate a market, coordinate their work, and synthesize their findings into a research report. If you're into finance, this is a solid primer on multi-agent systems and context management. Go get that alpha. (full length handbook): freecodecamp.org/news/build-… You've probably read this before, but the freeCodeCamp community is building tons of interactive courses on math, programming, computer science, world languages, and more. All of these are open source and available to everyone. If you've read this far, you should totally join the 9,103 chill people who support our charity's mission each month: freecodecamp.org/donate Quote of the Week: “Don’t comment bad code. Rewrite it.” — Brian Kernighan and P. J. Plauger, authors of the seminal C book The Elements of Programming Style way back in 1974

This weekend learn some low-level game dev! Make pixel graphics in C with this FREE 2-hour course. Here are this week's 5 learning resources worth your time: 1. freeCodeCamp just published a course that will teach you how low-level computer graphics work by coding your own software renderer in C. You'll learn how to represent images as pixel data, draw graphics to the screen, and transform 3D objects into 2D images. This'll teach you what's really happening under all those layers of abstraction in modern game engines like Unreal. (2 hour YouTube course): freecodecamp.org/news/master… 2. Learn how Cross-Site Request Forgery attacks work from the ground up. This handbook explains the browser mechanics that make CSRF attacks possible, and how malicious websites can exploit a user's authenticated session. (full length handbook): freecodecamp.org/news/csrf-f… 3. If you're studying engineering but don't know much about Python, this is a good place to start. You'll install a development environment, then learn the absolute basics. Run calculations, analyze data, and visualize your results. You'll get plenty of practice turning mathematical models into code. (4 hour YouTube course): freecodecamp.org/news/python… 4. freeCodeCamp also published a handbook that will teach you emerging best practices for building agents that interact with multiple users. Think the creepy merchant from Resident Evil 4. What're ya' sellin'? First you'll learn how authorization flows work. Then you'll manage access tokens and give your agents narrowly scoped access to external tools like GitHub and Slack. (full length handbook): freecodecamp.org/news/ai-age… 5. Finally, learn how to test AI-powered features in your Flutter apps. Model output is stochastic (read: unreliable) which makes traditional testing approaches a lot freakin' harder. This handbook will show you how to isolate model integrations, control dependencies, and write reliable tests without making unnecessary calls to external APIs. If you're building mobile apps with AI features, this is well worth bookmarking. (full length handbook): freecodecamp.org/news/how-to… The freeCodeCamp community is kicking butt and taking numbers. I hope you are too. If you've got some funds to spare, join the 9,031 kind folks who support our charity and our mission: freecodecamp.org/donate Quote of the Week: “C has the power of assembly language. And the convenience of... assembly language.” — Dennis Ritchie, creator of the C programming language

If you feel behind, don't worry. You're only 81 minutes behind.

I made a "sus phone" for the apps I don't trust with my data.

Even if you're not one of the devs Anthropic is letting sit for this exam, this is still 13 HOURS of FREE learning to plow through this weekend.

Learn some Python this weekend. 🐍 On the house, as always.
