Writing software while sleeping to predict NFL games.
An AI agent, a Docker sandbox, and 53 minutes later: a working ML microservice.
Conference Championship predictions:
โข Broncos over Patriots (100%)
โข Seahawks over Rams (94%)

AI writes code. AI writes tests. What could go wrong?
Mutation testing result: 85% of bugs caught.
After hiding the implementation from the AI: 92%.
Property tests found 11 real bugs all others missed.

"Just use a different LLM for tests."
Doesn't work.
The moment any LLM sees your code, it reasons about what it does, not what it should do.
Independence needs different information, not different systems.

The T in vibe coding stands for testing.
At 39C3, Johann Rehberger () showed how AI coding assistants can be hijacked through prompt injection. He calls compromised agents "ZombAIs."
The attack surface exists because we stopped looking. When the AI writes code AND tests, that's not verification. That's confirmation.
Super excited to share that Iโll be speaking at PyCon+Web 2025 on January 25th in Berlin! ๐คโจ My talk, "๐๐ฑ๐ด๐ฒ ๐๐ ๐๐ถ๐๐ต ๐ ๐ถ๐ฐ๐ฟ๐ผ๐ฃ๐๐๐ต๐ผ๐ป ๐ฎ๐ป๐ฑ ๐ง๐ฒ๐ป๐๐ผ๐ฟ๐๐น๐ผ๐ ๐ณ๐ผ๐ฟ ๐ ๐ถ๐ฐ๐ฟ๐ผ๐ฐ๐ผ๐ป๐๐ฟ๐ผ๐น๐น๐ฒ๐ฟ" is going to dive into the fascinating world where AI meets tiny tech.
It's like fitting an elephant or mammoth into a shoebox! ๐๐ฆ
Canโt wait to meet all the amazing Python and web enthusiastsโletโs make it awesome! ๐

Imagine having devices that can understand voice commands without relying on the internet! Iโll show how to run machine learning models on a tiny microcontroller, enabling AI-powered features like wake words and handwritten number recognition. Join me and learn more about Edge AI and TinyML.
