If you have multiple applications on Heroku and would like to use a single Logentries account for all of them, this is how you do it. Basically, do not use add-ons, and send all drains to your account.

In your Logentries account, click on Add Log
Select Manual
In the form that appears, input the following:
- Log Name: access.log
- Select Set: new set named myapp-{environment}, for instance myapp-staging (at least, this is how I like to name my entries)
- Select the Plain TCP, UDP - logs are sent via syslog option
Click on Create Log Token

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.
