Python FastAPI Tutorial (Part 19): Deploy with Docker - Serverless Containers and Custom Domain

In this video, we'll be learning how to deploy our FastAPI application using Docker and Google Cloud Run. We'll containerize our app by writing a multi-stage Dockerfile, set up a serverless PostgreSQL database with Neon, deploy our container to Cloud Run, and configure a custom domain with HTTPS. We'll also add security headers to our application through middleware. This is a different approach from the VPS deployment in the previous video, where instead of managing our own server, Google handles the infrastructure for us and our app can scale to zero when nobody's using it.

Python FastAPI Tutorial (Part 18): Deploy to a VPS - Security, Nginx, SSL, and Custom Domain

In this video, we'll be learning how to deploy our FastAPI application to a VPS (Virtual Private Server) so that it's live and accessible on the internet. We'll walk through the entire process, starting with a fresh Ubuntu server and hardening it with SSH key authentication, a firewall, and brute force protection. From there, we'll set up Nginx as a reverse proxy, enable HTTPS with a free SSL certificate from Let's Encrypt, point a custom domain to our application, and use systemd to manage the app as a service so it starts on boot and restarts automatically if it crashes. By the end of this video, you'll have a secure, production-ready FastAPI deployment with a real domain name. Let's get started...

Python FastAPI Tutorial (Part 17): Testing the API - Pytest, Fixtures, and Mocking External Services

In this Python FastAPI tutorial, we will learn how to test our FastAPI application using Pytest, HTTPX's AsyncClient, and mocking tools like Moto. We'll start by setting up our test structure and fixtures in conftest.py, including a transactional rollback pattern for fast and isolated database tests. From there, we'll write tests for our API routes covering authentication, CRUD operations, file uploads, ownership checks, and background tasks. We'll also learn how to mock external services like AWS S3 and email sending, so our tests don't depend on real infrastructure. By the end of this video, you'll have a solid set of real-world testing patterns that you can apply to your own FastAPI projects. Let's get started...

How to friction-max your learning with software engineer Jessica Rose [Podcast #216]

Today Quincy Larson interviews Jessica Rose. She's a dev and teacher who's worked on open data projects at Mozilla and lots of open source projects. We talk about: - How the whole world is hard, and how embracing that difficulty rather than avoiding it can make you a better thinker - The Bad Website club, a free online bootcamp where people learn front end development together that starts this April - Why building "silly little things" is one of the best things you can do as a learner Links from our discussion: - Bad Website Club announcement: https://www.freecodecamp.org/news/bad-website-club-bootcamp-based-on-freecodecamp-rwd-cert/ - Study Jess mentions about AI and worker productivity: https://www.raconteur.net/technology/ai-meaningful-work Community news section: 1. freeCodeCamp just published a new Python course that will teach you how to program your own aerial drone. You don't need to own a drone. You'll use the PySimverse simulator to practice autonomous flight. First you'll learn the basics of drone components, 3D movement, and common computer vision tasks. Then you'll learn about navigation, image capture, hand gesture control, autonomous following, and more. (2 hour YouTube course): https://www.freecodecamp.org/news/master-ai-drone-programming/ 2. freeCodeCamp also published a massive course that will teach you how to program NVIDIA's H100 GPUs using CUDA. You'll learn about CUTLASS optimizations, multi-GPU scaling, and the primitives developers use to train large models. (24 hour YouTube course): https://www.freecodecamp.org/news/cuda-programming-for-nvidia-h100s 3. If you've ever wanted to build a video editor or live streaming tool that runs entirely in a browser, this handbook is worth bookmarking. You'll see how the WebCodecs API can give you low-level, hardware-accelerated control over video processing. You'll learn key concepts like video frames, codecs, containers, and muxing. (full length handbook): https://www.freecodecamp.org/news/the-webcodecs-handbook-native-video-processing-in-the-browser/ 4. Kubernetes doesn't have a built-in user database. Instead it relies on a chain of authenticators. This course will teach you how x509 client certificates work, why they're not ideal for human users in production, and how to instead deploy your own self-hosted browser-based OpenID Connect login. (29 minute read): https://www.freecodecamp.org/news/how-to-authenticate-users-in-kubernetes-x509-certificates-oidc-and-cloud-identity/ 5. The song of the week is 1983's "Oblivious" by Scottish New Wave band Aztec Camera. I love the song's Django Reinhart-style Flamenco guitars, mischevous bass line, and stereo percussion. Believe it or not, front man Roddy Frame was only 18 years old when he wrote the song, sang it, and played it's iconic guitar solo. https://www.youtube.com/watch?v=NdVb4Iuq0e8

Python FastAPI Tutorial (Part 16): AWS S3 and Boto3 - Moving File Uploads to the Cloud

In this video, we'll be learning how to make our file storage production-ready by moving uploaded images from local disk into AWS S3. We'll walk through creating an S3 bucket, configuring the bucket policy and IAM permissions, and integrating boto3 into our FastAPI application. We'll also refactor our image processing to separate it from the storage layer and handle boto3's blocking calls properly in our async app. By the end of the video, you'll have a production-ready file storage setup that can scale beyond a single server.

How to learn programming and CS in the AI hype era – interview with prof Mark Mahoney [Podcast #215]

Today Quincy Larson interviews Mark Mahoney. He worked as a dev before becoming a computer science professor. He's taught computer science for 23 years at Carthage College, a 180-year-old US university. He's also taught thousands of developers through his free programming courses built on top of his own open source course platform, Playback Press. We talk about: - Why learning programming the hard way is still the right way - How to not deskill yourself when programming with LLM tools - And why now is a great time to study computer science Support for this podcast comes from the 10,113 kind folks who donate to our charity each month. Join them and support our mission at https://donate.freecodecamp.org Get a freeCodeCamp tshirt for $20 with free shipping anywhere in the US: https://shop.freecodecamp.org Links from our discussion: - Playback Press, Mark's free interactive courses: https://playbackpress.com/books - Mark's personal website: https://markm208.github.io/ - One of the many vibe-coded projects Mark mentions: https://markm208.github.io/vibeCodingInClassTools/git-workflow-simulator.html - Mark's tutorials on freeCodeCamp: https://www.freecodecamp.org/news/author/markm208/ Community news section: 1. freeCodeCamp just published a new course on AI-assisted software development. You'll learn common terminal workflows and tips for “pair programming” alongside LLM tools. You'll also get exposure to tools like GitHub Copilot, Claude Code, Gemini CLI, and OpenClaw. At the end of the day, the entire goal of using these tools is to build more features without compromising the maintainability of your codebase. (90 minute YouTube course): https://www.freecodecamp.org/news/ai-tools-for-developers/ 2. freeCodeCamp also published a beginner level course on AI literacy for everybody that you can also share with your family. First you'll learn about the two traits that definte artificial intelligence: autonomy and adaptivity. Then you'll build your own image classifier right on your own phone or laptop. This course also delves into considerations like algorithmic bias the environmental costs of training and running LLM systems. (1 hour YouTube course): https://www.freecodecamp.org/news/ai-literacy-for-everybody/ 3. Learn how to build your own QR code generator using JavaScript. This tutorial will walk you through generating QR codes entirely in a browser without the need for a backend. You'll learn how to validate input, clear previous output, and use a JavaScript library to render the code instantly on the client side. Then you'll see how to extend the project with downloads, custom styling, WiFi support, and more.

Lessons from 15,031 hours of coding live on Twitch with Chris Griffing [Podcast #214]

Today Quincy Larson interviews Chris Griffing is a software engineer and prolific streamer of live coding on Twitch. He spent 10 years as a "snowboard bum" doing odd jobs at ski resorts to facilitate him spending as much time on the mountain as possible.
