LLM Wiki

A pattern for building personal knowledge bases using LLMs.

This is an idea file, it is designed to be copy pasted to your own LLM Agent (e.g. OpenAI Codex, Claude Code, OpenCode / Pi, or etc.). Its goal is to communicate the high level idea, but your agent will build out the specifics in collaboration with you.

The core idea

Most people's experience with LLMs and documents looks like RAG: you upload a collection of files, the LLM retrieves relevant chunks at query time, and generates an answer. This works, but the LLM is rediscovering knowledge from scratch on every question. There's no accumulation. Ask a subtle question that requires synthesizing five documents, and the LLM has to find and piece together the relevant fragments every time. Nothing is built up. NotebookLM, ChatGPT file uploads, and most RAG systems work this way.

Problem

Your host machine (MacOS) get's an ip address from your VPN provider and possibly some routes to the remote network, but your VPN provider has no clue about other networks inside your host machine. That's what blocks UTM (QEMU) virtual machines from accessing the vpn network. UTM generates a new network for vm's and route entries for it automatically. This network is not known at the other side of the VPN, so although your PINGs reach the VPN the receiver of that ping does not know where to send it back.

Note on sizes: a lot of those might be inaccurate as there might be many microservices required aside from the core release/docker image. I haven't tested these recently so I'm not sure

Certighost (CVE-2026-54121)

Authors: @h0j3n, @aniqfakhrul
Date: July 24, 2026

---

Certighost is an Active Directory Certificate Services (AD CS) vulnerability that allowed a low-privileged domain user to impersonate a Domain Controller and achieve domain compromise in the tested AD CS configuration. The issue was addressed in the July 2026 security updates.

The vulnerable path is an AD CS enrollment fallback known as a chase during directory-object resolution. By supplying request attributes such as cdc, an attacker could cause the Certification Authority (CA) to ask an attacker-controlled host for identity data belonging to a Domain Controller. The CA then used that data while issuing a certificate.
