Building an NFL Game Predictor While I Slept: The Ralph Wiggum Paradigm in Action I went to bed. 53 minutes later, I had a working NFL game prediction microservice. The Ralph Wiggum paradigm turned a concept document into a deployed applic...

Writing software while sleeping to predict NFL games.
53 minutes. 25 tasks. Conference Championship picks:
Broncos 100% 🐴
Seahawks 94% 🦅
Patriots fans, I'm sorry.

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.

The T in vibe coding stands for testing (Part 2): What independence actually means Using a different LLM for testing sounds like it would create independence. It doesn't. The moment any model sees your implementation, it reasons about what ...

"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 Vibe coding's dirty secret - AI-generated tests only prove the code does what the AI thought it should do. At 39C3, security researcher Johann Rehberger show...

The T in vibe coding stands for testing.

At 39C3, Rehberger showed AI coding assistants getting hijacked via prompt injection. He calls them "ZombAIs."

When AI writes code AND tests, that's not verification.

maybe the A in our DNA stands for Autobahn 🤷

a generated image of a fast car in front of a jacket

I used a product image of a jacket and placed a generated car in front of the jacket. Therefore, I used #ControlNet and #StableDiffussion and then mixed everything together. Unfortunately the denim jacket doesn't fit to a fast car.
