Evergreen Notes: Write Notes That Compound Over Time

Evergreen Notes: Write Notes That Compound Over Time

Notes that improve instead of decaying.

Most engineering notes are written once and forgotten. You capture something in a debugging session, paste it somewhere, and find it two years later with no context for why it mattered.

Model Routing: Stop Using One Model for Everything

Model Routing: Stop Using One Model for Everything

The right model for the right task.

Running a 70B parameter model to summarize a 200-word email is wasteful. Running a 3B model to review production code is reckless. Most systems live somewhere in between — and that’s where model routing comes in.

LLM Guardrails in Practice: What Actually Works

LLM Guardrails in Practice: What Actually Works

Control the risk, not just the model.

LLMs are unpredictable. They hallucinate, leak data, generate harmful content, or refuse legitimate requests. Guardrails constrain model behavior without sacrificing capability.

Memory Systems in AI Assistants

Memory Systems in AI Assistants

Working, structured, and retrieval memory for assistants.

Memory turns assistants from reactive to persistent, but it is also where many systems quietly rot. Surveys argue the short-term versus long-term split is no longer enough for modern agent memory; OpenAI and LangGraph SDKs point to a simpler stack — working memory, durable state, and retrieval.

Retrieval vs Representation in Knowledge Systems

Retrieval vs Representation in Knowledge Systems

Search is not knowledge structure

Most modern knowledge systems optimize retrieval, and that is understandable. Search is visible, easy to demo, and feels magical when it works. Type a question, get an answer.

LLM Wiki - Compiled Knowledge That RAG Cannot Replace

LLM Wiki - Compiled Knowledge That RAG Cannot Replace

Compiled knowledge for AI systems

The premise is simple: compiled knowledge is more reusable than retrieved fragments. RAG became the default answer to a straightforward question - how do I give an LLM access to external knowledge?
