I accidentally discovered how to compress a semester of learning into 48 hours.

A grad student at MIT showed me his NotebookLM setup. I thought he was just organized. Then I watched him pass a qualifying exam on a subject he'd never studied before.

Here's exactly what he did:

First: he didn't upload a textbook.

He uploaded 6 textbooks, 15 research papers, and every lecture transcript he could find on the subject.

Then he asked NotebookLM one question:

"What are the 5 core mental models that every expert in this field shares?"

Not "summarize this." Not "explain this topic."
Mental models. The stuff that takes professors years to develop.

But the next part is what broke my brain.

He followed up with:

"Now show me the 3 places where experts in this field fundamentally disagree, and what each side's strongest argument is."

In 20 minutes he had a map of the entire intellectual landscape of the field:
the debates, the consensus, the open questions.

Most students spend a full semester just figuring out what those debates even are.

Then he did something I've never seen before.

He asked:

"Generate 10 questions that would expose whether someone deeply understands this subject versus someone who just memorized facts."

He spent the next 6 hours answering those questions using the source material. Every wrong answer triggered a follow-up:

"Explain why this is wrong and what I'm missing."

By hour 48, he could hold a conversation with his thesis advisor without getting destroyed.

The tool didn't change. The questions did.

Most people treat NotebookLM like a fancy highlighter.
These students are using it like a private tutor who has read everything ever written on the subject.

The difference between a semester and 48 hours isn't the amount of content.

It's knowing which questions to ask.

Researchers say an advanced Linux malware framework was built in weeks with AI help, guided by a single skilled developer using an AI agent—resetting expectations for what one actor can build.

This is very interesting!!

I wrote an IDA plugin that queries #ChatGPT and explains decompiled functions. It's still very bleeding edge, but you can find the code here and try it out:

Christina Yuna Lee was a digital producer @splice. She was 35 y.o. Korean-American and a graduate of @RutgersU. She lived in a 6 story walk-up in Chinatown. On Sunday morning, a stranger followed her home and murdered her. May she find rest. May her family & friends find comfort.

I played DiceCTF this weekend and solved a V8 challenge. I bypassed the latest "Virtual Memory Cage" protection in V8 and here is how I achieved it XD https://t.co/5ihr5Tmsrh

Today I discovered my best C++ RE automation technique yet, which is alarmingly simple. Every name and type in this screenshot was applied automatically, no manual work. Details eventually when I finish my research binge.

This is strongly unacceptable! Disrespectful to the authors' immense effort to produce quality work, artificially slows progress in the field, and destroys students' excitement for academic research.
