Somewhere, Elvis is still alive

Forget one giant Enterprise. Michio Kaku says we could send billions of nanoships to a star instead.

Nanotechnology, one atom at a time, from my chat with him on Hanselminutes.

Billions of tiny starships

Why don't we have Star Wars ray guns? Michio Kaku says the physics works. What's missing is a power pack powerful enough to hold in your hand.

Yes, I brought up my laptop battery.

Why we don't have ray guns

In high school, Michio Kaku built a particle accelerator in his garage. It blew every circuit breaker in the house.

Then I asked what he wrapped the wire around.

He built an atom smasher at home

Kat does not want to look at code after 5. She says that is normal, and it is not a character flaw.

You do not have to code after 5

Kat Excellence walked me through why she chose a CS degree over a bootcamp. Student-only internships, a broader education, and a network that reaches Big Tech.

Why Kat picked college over a bootcamp

Kat uses career envy as a signal. If someone's path makes you jealous, that is data about what you want.

Kat says juniors are the best code reviewers on the team. No context means you catch what the seniors stopped seeing.

Save a 4K wallpaper as a JPEG, then try to get the 4K back. You can't. A prompt is lossy too.

Hand it to someone else and you get a different app. Clone the repo and you get mine.

Prompting is not programming, people.

Prompting is not programming, people

Prompt engineering is not a thing. If two people type the same prompt and get different code, the prompt was ambiguous. That is not programming.

A young man who's a sophomore in high school emailed me to come on his podcast that he does with his friend, and I had so much fun. I decided to make it a crossover episode. Check out "Compile after Class" on this week's episode!

Compile after Class Crossover Episode

Felix Rieseberg came to computing through poetry, and that background gives him a unique lens for explaining language models. A longtime engineer, Felix now gets to watch AI evolve from the inside. In this episode, Scott and Felix explore why language models are surprisingly easy to understand despite feeling magical, what it's like to train a model from noise to coherence, and the bigger philosophical questions about intelligence that AI keeps surfacing. You can learn how AI really works by making your own in a weekend with his free site below.

Maynard Holliday spent 30+ years at the intersection of robotics, nuclear security, and defense technology, most recently serving as the Assistant Secretary of Defense for Critical Technologies. He's worked on everything from helping remediate Three Mile Island to securing tons of Soviet nuclear material in post-Cold War Ukraine to overseeing the Pentagon's critical technology portfolio including AI, hypersonics, and microelectronics. He shares what "trusted AI" really means, why he co-founded Black in Robotics, and how T'Challa and Tony Stark shaped his career more than you'd expect.

Varun Badhwar, CEO and Co-Founder of Endor Labs, joins Scott to explore the expanding software supply chain risk in the age of AI-generated code. They discuss how developers have gone from writing code to assembling it from layers of dependencies like open source, third-party libraries, and now the outputs of AI...and what all this means for security. From hallucinated npm packages that could be squatted on, to developers becoming part of the attack surface themselves, this is a wake-up call for anyone building software today.

Alexandra Lato, VP of Product at Stack Overflow, joins Scott to talk about how Stack Overflow is evolving for the age of AI agents. They explore the new "Stack Overflow for Agents" feature, where a single prompt bootstraps an agent with all the knowledge and APIs of Stack Overflow, and what it means for how developers, agents, and communities share and verify knowledge together.
