+Quote of the Week: *“The real skill for working with AI is communication. If you can’t explain precisely what you want, the tool will churn out junk. Soft skills suddenly matter a lot.”* — Software Engineer Nick Taylor on this week's freeCodeCamp podcast

+1. freeCodeCamp just published a new course that will teach you how to gracefully answer common LeetCode-style questions you'll get asked during developer job interviews. It covers essential data structures and algorithmic patterns. You'll build up your intuition so you can recognize which patterns to apply, and how to avoid brute force solutions. You'll start by learning fundamental data structures like Arrays, Sets, and Hashmaps. Then you'll bust out Python and learn about Big O Notation, before moving on to more advanced concepts like Sliding Windows, Binary Search, Backtracking, and Priority Queues. (1 hour YouTube course): https://www.freecodecamp.org/news/data-structure-and-algorithm-patterns-for-leetcode-interviews/
+
+2. And if you want to go much deeper into Python Machine Learning, this week we also published a comprehensive Computer Vision course. You'll use the open source PyTorch library to implement one of the most influential convolutional neural networks: Visual Geometry Group Networks (VGGNets). You'll learn the theoretical origins of VGGNets and the math that powers them. Then you'll fire up Colab and start implementing one for yourself. Whenever you're looking for courses on advanced topics like this, remember to use freeCodeCamp's search bar. We have thousands of tutorials, books, and full-length courses like this.

+
+3. Want to get a developer job? Be shameless. That's the advice of this week's freeCodeCamp podcast guest, Namanh Kapur. He's a senior software engineer at LinkedIn and has a ton of hot takes on where the field is heading. He shares tips for how to interact with recruiters, which foundational developer skills he thinks you should prioritize learning, and how to get hired in what he calls the “post-LeetCode world.” (1 hour watch or listen in your favorite podcast app): https://www.freecodecamp.org/news/we-are-truly-in-the-hackathon-era-namanh-kapur-interview-podcast-180/
+
+4. Not every codebase is run by a team of developers. A lot of projects are built by a single person who's just iterating on their ideas and trying to find customers. That's where this week's Ultimate Tool Stack for Indie Hackers comes in. Manish breaks down a lot of Lean Startup Methodology and translates it into specific tools you can use to quickly build the first version of your products. He covers prototyping tools, payment gateway tools, analytics, and more. (10 minute read): https://www.freecodecamp.org/news/ultimate-tool-stack-for-indie-hackers/
+
+5. freeCodeCamp also published this quick guide for more experienced developers. It shares some practical tips for incorporating AI tools into your day-to-day programming workflows. Author Spruce Emmanuel doesn't pull any punches or sugar-coat any of his observations about the utility of these tools or the future of manually writing most code. (12 minute read): https://www.freecodecamp.org/news/how-to-use-ai-effectively-in-your-dev-projects/
+
+Quote of the Week: *“Let's get one thing straight: AI is here to help, not to replace. Your job, my job, was never just to write code. Writing code was always just a part of it. Our real job is to build software solutions that work.”* — Spruce Emmanuel, developer and prolific freeCodeCamp contributor, in his article on incorporating AI tools into your software development workflows

+1. freeCodeCamp just published this comprehensive guide to AI app security and the most common vulnerabilities. You'll learn about Threat Modeling, Prompt Injection, Data Poisoning, supply chain risks, and more. (1 hour YouTube course): https://www.freecodecamp.org/news/learn-how-to-build-security-into-ai/
+
+2. JavaScript is the most popular language on the planet. But it's also super duper prone to errors. Luckily, freeCodeCamp just dropped this comprehensive handbook to help you understand how JavaScript's error handling works. You'll learn about Try-Catch, Error Rethrowing, the Finally keyword, and the Error Object itself. We also show tons of example code that you can scrutinize and learn from.

+
+3. On this week's podcast, I interview a developer who had to apply to 800 jobs, but eventually landed one. Braydon Coyer started out building mobile apps in high school. At one point his iPhone game even out-sold Angry Birds for a day or two. He shares tons of strategies for applying for developer roles, sane ways to integrate AI into your developer workflows, and how to switch from mobile app dev to full stack dev. This dude is a blast.

+
+4. I'm a huge fan of data visualization, and I love me some D3.js. So I was jazzed about this new course that'll help you shore up your Data Viz fundamentals. You'll go from bare-bones scatter plots to dynamically updating charts with fancy animations. If you want to learn how to make your data more accessible and more fun, this course is for you. (90 minute YouTube course): https://www.freecodecamp.org/news/learn-interactive-data-visualization-with-svelte-and-d3/
+
+5. As you may know, freeCodeCamp is a big open source project. And we have tons of developers who jump in to help us improve our curriculum and our codebase. But it's common for many of them to lose steam and drop off the map. This guide will help ensure that this doesn't happen to you. It'll give you actionable tips for setting open source goals, finding the right projects to get involved in, engaging with fellow devs, and more.

+Quote of the Week: *"When I was learning to code, the big picture didn’t click until I needed to solve real problems. That’s when variables and arrays started making sense — not in theory, but in practice."* — Software Engineer Braydon Coyer on this week's freeCodeCamp podcast

+1. freeCodeCamp just published this comprehensive course that will teach you how to build apps using the LAMP Stack – Linux, Apache, MySQL, PHP. This is a classic toolchain that a huge number of websites still use to this day. You can code along at home and build your own clone of Google Calendar – complete with multi-appointment support and booking conflict logic. Then you'll use JavaScript to add a dynamic user interface. This project will help you expand your horizons and get in some serious reps.

+
+2. You may have heard the term “vibe coding”, where you write the specifications for your app, then hand it over to code generation agents who write the code for you. This approach has been a bit polarizing in the developer community, with vocal critics and vocal advocates. My advice is don't listen to any of them. Think for yourself. freeCodeCamp just published this course that will introduce you to vibe coding tools like n8n – an open source workflow automation tool – so you can wire together APIs and services without needing to write a ton of code manually. (2 hour YouTube course): https://www.freecodecamp.org/news/how-to-vibe-code-with-help-from-n8n/
+
+3. On this week's podcast I interview Joe Hill. He's a software engineer who works on a data platform for NASA. Joe taught himself programming for 4 years while working as a janitor. As the single father of two Autistic boys, he first used his programming skills to build an iPad app to help them learn how to talk. He shares tons of practical tips for learning new skills and for getting things done inside big orgs.

 1. We just published a full-length interactive book by computer science professor and freeCodeCamp contributor Dr. Mark Mahoney. It will teach you the foundations of both back end and front end web development. You'll learn some Node, Express, SQLite, GraphQL, Web Components, React, and more. Mark even built his own open source “code playback” system to walk you through the book's code step-by-step with detailed explanations. Pretty cool.
