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.

GitHub Search Syntax for Finding API Keys/Secrets/Tokens

As a security professional, it is important to conduct a thorough reconnaissance. With the increasing use of APIs nowadays, it has become paramount to keep access tokens and other API-related secrets secure in order to prevent leaks. However, despite technological advances, human error remains a factor, and many developers still unknowingly hardcode their API secrets into source code and commit them to public repositories. GitHub, being a widely popular platform for public code repositories, may inadvertently host such leaked secrets. To help identify these vulnerabilities, I have created a comprehensive search list using powerful search syntax that enables the search of thousands of leaked keys and secrets in a single search.

Search Syntax:

(path:*.{File_extension1} OR path:*.{File_extension-N}) AND ({Keyname1} OR {Keyname-N}) AND (({Signature/pattern1} OR {Signature/pattern-N}) AND ({PlatformTag1} OR {PlatformTag-N}))

Fixing slowdowns in KDE (6 or newer)

Recently I took to debugging reasons that my machine was having issues with lag when typing into the KDE application launcher. I'm also a heavy user of KRunner, and I was also having lag when using it. To summarise, when I begun I had all of the following symptoms

1. The KDE launcher ('Start Menu') was randomly and intermittently freezing and sometimes taking a long time to come up
2. KRunner (Called 'Plasma Search' in the UI and settings) was freezing and hitching, and sometimes only only coming up after a long delay.
3. When opening Dolphin, sometimes it would take up to 10 seconds to launch!
4. Even opening kate from the terminal took a long time to launch
5. Entering 'edit mode' of the panels freezes for a very long time, eventually delivering all keyboard/mouse events at once.
