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.

mTLS 配置

对于mTLS的配置的证书来说，有如下的提示。

三个文件。对于大多数系统，如：MySQL, Redis，PostgreSQL。会需要三个文件：CA证书 + CERT 和 KEY。可以在我的这个开源项目（https://github.com/haoel/mTLS/tree/main/certs ）中找到我生成的CA，以及 Server 和 Client的 .crt 和 .key 文件。生成的方法也在我的那个开源项目中了。
两个文件。对于有的系统，比如：MongoDB，他只要两个文件，一个是CA，一个是 pem 文件，对于pem文件，你可以直接把上面的 .crt 和 .key 合并了就好了。如：cat server.crt server.key > server.pem
JKS文件。对于一些系统，比如：Kafka 和 Zookeeper。他要的不是上面的明文的格式，他要的是一种jks的格式，这是Java的格式。怎么从上面的明文的方式转到jks的文件。需要经过下面几步。
