freeCodeCamp Podcast

Today Quincy Larson interviews Jason Lengstorf. He's a college dropout who taught himself programming while building websites for his emo band. 22 years later he's worked as a developer at IBM, Netlify, run his own dev consultancy, and he now runs CodeTV making reality TV shows for developers.
 
We talk about:
 - How many CEOs over-estimated the impact of AI coding tools and laid off too many devs, whom they're now trying to rehire
 - Why the developer job market has already rebounded a bit, but will never be the same
 - Tips for how to land roles in the post-LLM résumé spam job search era
 - How devs are working to rebuild the fabric of the community through in-person community events

2. Before modern Large Language Models, scientists and developers worked with more fundamental Natural Language Processing tools. freeCodeCamp just published a handbook that will help you understand the tools that power chatbots, machine translation, text summarization, and more. You'll learn how computers analyze syntax, model semantics, and interpret context. Then you'll use popular Python libraries to apply those concepts to real projects.

#194 First dev job at 45 – Interview with self-taught freeCodeCamp grad Eric Carlson

Kaleb Garner is a software engineer working at a medical technology app company. He got a scholarship to play baseball at a state university, but a serious knee injury ended his career and he dropped out.
 
After moving back in with his parents and working at an optometry office, he decided to teach himself programming. He used freeCodeCamp and 100Devs to learn for free, and got his first front end developer job when he was only 19. He has since expanded his skills to work on large legacy Python and C# codebases.
 
We talk about:
 - How his Major League Baseball goals and his dream of becoming a doctor ended in the same catastrophic semester
 - His grind to get his first developer role after only 20 carefully researched job applications
 - Getting laid off right before his wedding and losing all discipline in his frantic job search
 - Tips for making your skillset and your network layoff-resilient

1. freeCodeCamp just published an in-depth Harvard course that will teach you SQL and relational databases. You'll learn key concepts like CRUD operations (Create, Read, Update, Delete). You'll also learn how to normalize data, join tables, and index your databases for faster performance. You'll use real-world datasets and write your own queries in SQLite, before moving on to working with PostgreSQL and MySQL. (11 hour YouTube course): https://www.freecodecamp.org/news/learn-databases-and-sql-from-harvard-university
 
2. This advanced Python Machine Learning course will teach you the history of computer vision architectures. You'll learn about design philosophies like LeNet, AlexNet, Xception, and Vision Transformers. You'll see side-by-side comparisons, and learn how they've progressed over the past few decades. (5 hour YouTube course): https://www.freecodecamp.org/news/the-history-of-deep-learning-vision-architectures
 
3. freeCodeCamp also published this handbook that will teach you all about JSON Web Tokens, which are key to modern authentication and security. You'll learn their history and how they work, through a series of helpful diagrams and code examples.

#193 From injured athlete to software engineer with Kaleb Garner

Evan You is the creator of the popular Vue JavaScript library for front end development and the Vite JavaScript build tool that a lot of devs use as a boilerplate for their new projects. He's a self-taught developer based in Singapore.
 
He shares tips for:
 - Getting involved in open source
 - Leading open source projects and attracting sponsors
 - And how to use AI as a thinking assistant rather than just as a coding assistant
 
We also talk about his thoughts on the Chinese open source scene, a new documentary that just came out about Vite, and his new project: Void 0.
 
Links from the news section:
 
1. freeCodeCamp just published a new in-depth course that will teach you full stack development fundamentals from the ground up. It covers front end development tools like HTML, CSS, and JavaScript. Then it moves to back end development tools like Node, SQL, and TypeScript. You can code along at home and build a variety of projects while getting exposed to a ton of concepts. (47 hour YouTube course): https://www.freecodecamp.org/news/become-a-full-stack-developer-with-one-video/
 
2. We also just completed work on this new Go programming course where you build your own movie streaming app. Go is a fast back end language, and here we're pairing it with the Gin-Gonic web server framework. As you build this project, you'll also integrate your movie database with OpenAI's API to analyze data and give your users personalized movie recommendations.

3. When browsing the web, you may see the error message that something has been "blocked by CORS policy." CORS stands for Cross-Origin Resource Sharing. When fetching data, if the domain of the requester is different from the domain of the receiver, your browser will reject that request. It's an important security measure, but it can also be a headache for developers trying to maintain their web apps. Luckily, freeCodeCamp just published this tutorial – chock full of theory and code examples – to help you understand the basics.

4. You've probably heard people throw around terms like Deep Learning, Machine Learning, and Generative AI. But what do they mean in relation to one another? This quick article breaks down the jargon for you in plain English. (10 minute read): https://www.freecodecamp.org/news/machine-learning-vs-deep-learning-vs-generative-ai/
