Today Quincy Larson interviews Carl Brown, who runs the Internet of Bugs YouTube channel and has worked as a dev at Amazon, IBM, Sun Microsystems, and startups for over 37 years.
We talk about:
- The hype versus the utility in LLMs and agent code generation tools
- Why you might want to target developer jobs at smaller companies, and how these differ from big tech
- How everyone will face agism eventually. Carl argues that a consulting career is a great escape hatch.

Today Quincy Larson interviews Landon Gray. Hes a software engineer who worked at agencies for years. Then he taught himself AI assisted software development. And now hes helping other devs do the same.
Landons 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.

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 youll 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 doesnt break when you add new features. Prolific freeCodeCamp instructor Beau Carnes teaches this course. Hell introduce you to the Testing Pyramid and show you how to balance fast unit tests against complex end-to-end user journeys. Youll 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 dont 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.

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. Youll also learn how to set up experiment tracking with MLflow, versioning with DVC, GPU passthrough, and other advanced techniques.
