Stanford's youngest instructor on InfoSec, AI, catching cheaters - Rachel Fernandez [Podcast #217]

Today Quincy Larson interviews Rachel An Fernandez. She's a computer science student at Stanford and the youngest instructor at the entire university. She recently helped organize TreeHacks, Stanford's annual hackathon, which narrowed 15,000 applicants down to just 1,000 participants. They built projects over a single weekend and competed for a million dollars in prizes. Rachel grew up in Westminster, a small California town with a largely Mexican and Vietnamese population. 70% of students at her high school had family incomes so low that qualified for free school lunches. And Rachel was the first student from there to get into Stanford in years. We talk about: - The state of computer science education in 2026 - Her thoughts on C++, a language she teaches at Stanford, and its continued importance - And her tips for how devs should use AI tools without "deskilling" themselves Support for this podcast comes from the 10,113 kind folks who donate to our charity each month.

You'll learn how to automate your routine daily tasks by piping together triggers and actions. By the end of the course, you'll have your own Model Context Protocol server that can share info between your productivity apps and your agents. (4 hour YouTube course): https://www.freecodecamp.org/news/reclaim-your-time-master-automation-with-zapier/ 2. freeCodeCamp also published a full-length handbook on data quality. You'll learn the most common ways that bad data enters a system, and how to prevent them. You'll get exposure to the different layers where data validation needs to happen: front end, back end, database, business logic, and data ingestion. The handbook will also walk you through testing strategies to keep bad data out of your projects.

AI Governance may sound like something only managers need to worry about. But in practice, it's us developers who have to actually build the responsible AI systems. You can bookmark this new freeCodeCamp handbook and code along with four hands-on Python projects: a model card generator, a bias detection pipeline, an audit trail logger, and a human-in-the-loop escalation system.

This 2024 banger features a heavily syncopated bass line that I think you'll love. The singer subtly alternates between French and Italian. And the music video is unique and all good vibes as well. https://www.youtube.com/watch?v=YC0ErOoQcUA
