Zettelkasten Explained Simply: How to Get Started
Notes pile up but the system doesn't work: links get saved, summaries get written, and none of it turns out to be usable later. Here's Zettelkasten without a Luhmann biography or an app comparison: what the method actually is, what notes you need, how to link them properly, and the one step to start with today.
AI and Learning: What Helps vs What Just Feels Like Progress
AI made explanations cheap, but it also got good at sounding convincing even when you haven't actually learned anything. Here's which scenarios actually train a skill, which ones just create the illusion of understanding, and the Rust example where I fell for it myself.
How to Connect AI Video Notes to Your Knowledge Base
A shelf of fifty AI video summaries nobody ever reopens isn't a knowledge base, it's an archive. A full pipeline for turning a summary into connected knowledge: separating source from knowledge, letting AI suggest links while you confirm them, and feeding what you already know back into the next video.
Prompt Engineering for Document Analysis
A prompt for document analysis isn't a one-off phrasing, it's a spec for a procedure: role, context, criteria, constraints, and output format.
