1. freeCodeCamp just published a Linux course that will teach you how to use some of the open source operating system's most powerful features. It's designed with both Linux beginners and intermediate users in mind. You'll learn Linux's file system with hard links, soft links, permissions, and root accounts. You'll also learn how to use grep, a command line tool for finding what you need inside large datasets. This course also includes interactive labs, so you can apply the new skills you're learning.

2. One of the most exciting areas of AI at the moment is Retrieval Augmented Generation (RAG). This freeCodeCamp Python course will teach you how to combine your own custom data with the power of Large Language Models (LLMs). You'll use LangChain, Mistral AI, Ollama, and more. You'll learn straight from Per Borgan, a software engineer, teacher, and long-time friend of mine.

3. On this week's freeCodeCamp podcast I interview designer and developer Colby Fayock. We talk about his journey from designing truck wraps to working as a software engineer. He also shares his day-to-day life building APIs and SDKs, and how he uses AI at work. Believe it or not, Colby doubled as a male model at ThinkGeek, which was kind of like The Sharper Image but for Star Wars fans. I think you'll enjoy our conversation.

5. The Black-Scholes Equation is the most important mathematical formula that most people have never heard of. Black-Scholes completely revolutionized corporate finance when it was discovered in 1973. This tutorial will explain how the formula works, and how you can implement it in Python. Then you'll use it to predict the price of concert tickets, and learn about its many other real-world applications.

Quote of the Week: *"Innovation must lead infrastructure for a simple but compelling reason: Innovation produces new types of products and markets, and it is virtually impossible to know how to run those markets efficiently before they are created."* — Myron Scholes, Nobel Prize winning economist and co-creator of the Black-Scholes Equation
