Community news section:

1. freeCodeCamp just published a new course on AI-assisted software development. You'll learn common terminal workflows and tips for “pair programming” alongside LLM tools. You'll also get exposure to tools like GitHub Copilot, Claude Code, Gemini CLI, and OpenClaw. At the end of the day, the entire goal of using these tools is to build more features without compromising the maintainability of your codebase. (90 minute YouTube course): https://www.freecodecamp.org/news/ai-tools-for-developers/

2. freeCodeCamp also published a beginner level course on AI literacy for everybody that you can also share with your family. First you'll learn about the two traits that definte artificial intelligence: autonomy and adaptivity. Then you'll build your own image classifier right on your own phone or laptop. This course also delves into considerations like algorithmic bias the environmental costs of training and running LLM systems. (1 hour YouTube course): https://www.freecodecamp.org/news/ai-literacy-for-everybody/

3. Learn how to build your own QR code generator using JavaScript. This tutorial will walk you through generating QR codes entirely in a browser without the need for a backend. You'll learn how to validate input, clear previous output, and use a JavaScript library to render the code instantly on the client side. Then you'll see how to extend the project with downloads, custom styling, WiFi support, and more. (7 minute read): https://www.freecodecamp.org/news/how-to-build-a-qr-code-generator-using-javascript/

4. I'm thrilled to announce that the Bad Website Club is back for another Responsive Web Design bootcamp based on freeCodeCamp's curriculum. It starts April 24 and runs for 10 weeks. You can join their Discord community and tune in for live streams. It's lead by volunteer devs who are passionate about helping folks learn CSS and JavaScript fundamentals.

5. Today's song of the week is 2008's Strange Overtones. The Talking Heads singer David Byrne blends his voice with Brian Enos, who handles organs and synths. The entire affair plays over an infectious palm-muted guitar line, and driving bass. This is a perfect mid-week jam. Put it on during during your commute. https://www.youtube.com/watch?v=GvZhpCYWFzs

At age 28 he taught himself PHP programming and started building websites for friends. In 2018 he started streaming himself programming on Twitch, which blew up during the pandemic and has lead to more opportunities as a dev and developer advocate.

We talk about:

- How he learned programming at age 28 and built projects for friends before going pro

- How learning Go made him a better Rust Developer and why you should be a polyglot programmer

- How Chris uses LLM tools but still builds most codebases manually

- Tips for building projects in public for anyone interested in also stream coding

Landon's famous for proving that RAG pipelines can be written in Ruby and popularizing Ruby as a language for building machine learning projects.

He works as an AI Engineer at a enterprise software company and runs a popular newsletter.

We talk about:

- How Large Language Models are just the raw fuel, and harnesses are the real engine to get things done

- Why building your professional network is so helpful for finding clients and landing job interviews

- Why Landon helped port Python machine learning libraries to Ruby, and why he thinks that – now that AI is just an API call away – the Ruby ecosystem is better-positioned than ever.

Community news section:

1. freeCodeCamp just published a new YouTube course that will teach you beginner Front-end Development skills like HTML, CSS, and JavaScript. You can code along at home and build a variety of projects: your own interactive quiz game, a currency converter app, and even a Trello-style kanban board. Along the way you'll learn how to use APIs and local storage to extend the functionality of these bite-sized apps. (12 hour YouTube course): https://www.freecodecamp.org/news/build-19-web-dev-projects-using-html-css-javascript/

2. Learn how to properly test your software and ensure it doesn't break when you add new features. Prolific freeCodeCamp instructor Beau Carnes teaches this course. He'll introduce you to the Testing Pyramid and show you how to balance fast unit tests against complex end-to-end user journeys. You'll also learn how to automate some of this testing using an open source library called Playwright and an LLM testing tool. (1 hour YouTube course): https://www.freecodecamp.org/news/software-testing-with-playwright/

3. More and more apps are relying on probabilistic LLM output alongside deterministic API calls. This makes life harder for devs who now need to ensure that hallucinations don't escape to end users. freeCodeCamp just published this advanced observability tutorial that will teach you emerging best practices and architectural patterns for dealing with this. (40 minute read): https://www.freecodecamp.org/news/build-end-to-end-llm-observability-in-fastapi-with-opentelemetry/

4. Learn how to containerize your MLOps pipelines. This tutorial is the result of hard-won deployment wisdom. The author spent three weeks debugging a Python library error due to dependency conflicts. His eventual answer: containerize entire project with Docker. This tutorial will show you how to structure your containers with multi-stage builds. You'll also learn how to set up experiment tracking with MLflow, versioning with DVC, GPU passthrough, and other advanced techniques. (40 minute read): https://www.freecodecamp.org/news/containerize-mlops-pipeline-from-training-to-serving/

6. Today's song of the week is 2006's Everybody by UK producers Basement Jaxx. If you're familiar with their work, you know you're in for a psychedelic yet silly romp. Between the spoons, bongos, and swooning chorus the song feels like it's held together with duct tape but it works. https://www.youtube.com/watch?v=OrMot81VE8g

1. freeCodeCamp just published a comprehensive DevOps course that will teach you how to deploy your apps to production safely. You'll build your own CI/CD (Continuous Integration / Continuous Delivery) pipeline. Along the way you'll learn about branching strategies, Jenkins Freestyle Jobs, GitFlow, Maven, and more. This is a perfect way to build your skills over spring break. (17 hour YouTube course): https://www.freecodecamp.org/news/ci-cd-in-production-with-jenkins/

2. Learn how to fine-tune an LLM to incorporate your own proprietary data. This is super useful if you need off-the-shelf LLMs to do novel tasks that they weren't originally optimized for. This course will teach you all about Parameter-Efficient Fine-Tuning, and how to use techniques like LoRA and QLoRA to train models on consumer-grade hardware. No data center needed. (12 hour YouTube course): https://www.freecodecamp.org/news/learn-how-to-fine-tune-llms-in-12-hours/

3. Learn how to protect your sensitive data by running your LLMs locally. This quick tutorial will show you how to get up and running with Ollama, Python, LangChain, and LangGraph. It will also walk you through the various trade-offs you face when you avoid sharing your data with big tech companies. (15 minute read): https://www.freecodecamp.org/news/protect-sensitive-data-with-local-llms/

4. Learn how agents are changing the field of software development. This in-depth tutorial will get you hands-on experience with building your own Flutter mobile app using Antigravity and Stitch. You don't even need to know Flutter. You just need to understand the core concepts and make the architectural decisions. You'll quickly see how sophisticated these tools have gotten over the past few months. (40 minute read): https://www.freecodecamp.org/news/learn-how-ai-agents-are-changing-development-by-building-a-flutter-app/

5. Today's album of the week is 1982 jazz fusion classic Mint Jams by Casiopea. This is the perfect record to put on when you want to get a ton of work done, and feel great in the process. For every song, each of the performers gets a solo. That means every track you're going to hear a spicy bass solo, keyboard solo, drum solo, and guitar solo. Love it. https://www.youtube.com/watch?v=6GEI3PpXEAo
