# This Weekend Learn System Design Fundamentals [FREE 2-hour Architecture Course] **作者**: Quincy Larson **日期**: 2026-04-17T13:06:13.000Z **来源**: [https://x.com/ossia/status/2045126686308450497](https://x.com/ossia/status/2045126686308450497) --- ![Image](/doc/701/image/img_bdd6ebcff147.jpg) freeCodeCamp just published a new FREE course on software system design fundamentals. Here are this week's five freeCodeCamp resources that are worth your time: 1. In this System Design Fundamentals course, you'll learn about databases, scaling, load balancing, and designing APIs with both REST and GraphQL. Once you grasp all these concepts, you'll be able to build better apps, websites, and back-end tools. (2 hour YouTube course): https://www.freecodecamp.org/news/learn-software-system-design/ 2. freeCodeCamp also published a full-length handbook on data quality. It'll introduce you to the types of data errors that silently break systems. Learn how to avoid missing fields, bad formats, logical inconsistencies, duplicate records, and more. You'll also learn how validation works across your front-end, back-end, database, service layer, and test suite. This is well worth bookmarking. (full-length handbook): https://www.freecodecamp.org/news/data-quality-handbook-data-errors-the-developer-s-role-validation-layers/ 3. On this week's freeCodeCamp podcast I interview Mark Mahoney. He worked as a dev then spent 23 years as a computer science professor. He also teaches thousands of devs through his programming courses he built on top of his own open source platform. We talk about why learning programming the hard way is still the right way, how to avoid deskilling yourself with LLM tools, and why now is a great time to study computer science. (1 hour watch or listen in your favorite podcast app): https://www.freecodecamp.org/news/how-to-learn-programming-and-cs-in-the-ai-hype-era-interview-with-dev-and-prof-mark-mahoney-podcast-215/ 4. freeCodeCamp also just published a course on using OpenAI's new Codex tool. Andrew Brown is a CTO who has decades of experience writing code manually. So it's fun to watch him put coding agents through their paces. You'll learn how to manage big context windows, work with sessions, sculpt your project guidance files, and use sandboxing to minimize the ever-present risk that your agents are going to go WarGames on you. (5 hour YouTube course): https://www.freecodecamp.org/news/openai-codex-essentials-ai-assisted-agentic-development-course/ 5. And if you're wanting to get started with Infrastructure as Code, this Terraform tutorial is good eats. You'll learn Terraform's core workflows, then use them to manage applications, databases, networking, secrets, scaling, and deployment pipelines in a massively repeatable way.
