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.

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.

mac 에서 docker-desktop을 대체하기

https://gist.github.com/leoh0/3b3c908f0e931d7c620d273c77ea3757

docker-desktop 를 2022년 1월 31일까지 대체해야 하기에 다들 여러 방법을 사용하실 것 같은데 windows에서는 사실 wsl2 를 사용하면서 docker 를 그대로 깔아서 쓸 수 있다는 것 때문에 큰 제약없이(eg. wsl이 결국 브릿지를 거치기 때문에 vpn등 사용시 mtu 조절이 필요할 수 있는 제약이 있음)사용 가능한데 맥은 사실 linux 스택을 그대로 사용할 수 없기때문에 vm을 올려야 하는 상태입니다.

불편한 점

하지만 이에 따라 여러가지 불편한 점들이 있습니다.

# Put this function to your .bashrc file.
# Usage: mv oldfilename
# If you call mv without the second parameter it will prompt you to edit the filename on command line.
# Original mv is called when it's called with more than one argument.
# It's useful when you want to change just a few letters in a long name.

Proxmox PVE Host Config Backup Script

This script can be used to backup essential configuration files from the Proxmox Virtual Enivronment (PVE) host.

The script will create backups using tar with specified backup prefix and date and time stamp in the file name. Script will also delete backups that are older then number of days specified.

Create backup script file

To create backup script that will be executed every day we can create backup script in /etc/cron.daily/ folder. We need to make it writeable by root (creator) only, but readable and executable by everyone:

touch /etc/cron.daily/pvehost-backup

# This script intend to mimic TimeMachine exclude list.
# As the exclude list can evolve between backups it has to be rebuilt before every backup
# Apple uses 5 types of excludes, four from the /System/Library/CoreServices/backupd.bundle/Contents/Resources/StdExclusions.plist file
# and files from applications where metadata says to not backup, these can be found usinf
# sudo mdfind "com_apple_backup_excludeItem = 'com.apple.backupd'"
