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.

Popular MCP Servers — What Each Service Actually Does

A quick-reference list of the 176 MCP servers from the Claude Code MCP registry, with plain-English descriptions of what the underlying service is — not just what the MCP connector does.

Notion	Wiki/docs/database workspace — teams use it for internal documentation, project tracking, and knowledge bases	Search, update, and automate workflows across your Notion workspace
Slack	Team messaging/chat platform — channels, DMs, threads, and integrations for workplace communication	Send messages, create canvases, and fetch Slack data

Which GGUF is right for me? (Opinionated)

Good question! I am collecting human data on how quantization affects outputs. See here for more information: ggml-org/llama.cpp#5962

In the meantime, use the largest that fully fits in your GPU. If you can comfortably fit Q4_K_S, try using a model with more parameters.

Q: What are the specific goals of developer relations?

There's no simple answer here, but I like to think of developer advocacy/evangelism/relations/etc as an extension of one (or more) of your company's core functions: product, sales, marketing and support. When I was a developer evangelist at Twilio, my team supported the Marketing org, so the team goals aligned with Marketing goals (driving signups).

Often you'll encounter a team of "Developer Advocates". The Google Chrome org has a team of Developer Advocates for example. These folks tend to align more with the Product organization, and their goals/metrics likewise align with the broader goals/metrics of the Product org.

Q: How do you measure it?

You can use the baseline metrics associated with your functional groups (i.e. top of funnel signups for Marketing) and then layer on metrics that capture the impact that the team is having in isolation from the overall organization. Example: developers who signed-up for your product because an evangelist

👀📎 It looks like you're preparing to MC a conference...

🚨 GIANT DISCLAIMER: This stuff is far from authoritative. But it's what I think works for me, and what I enjoy in an MC when I'm attending a conference.

Biggest tip - enjoy yourself.

Adding "Copy" (to Clipboard) Button

If you would like to add a button to your fenced code blocks so that users may copy the code, you can do so in Docusaurus. You will have to add some code to your Docusaurus project, as seen below.

Under static/js, create a file called code-block-buttons.js with the following:

// Turn off ESLint for this file because it's sent down to users as-is.
/* eslint-disable */
window.addEventListener('load', function() {

For example, to override the AppBar (https://material-ui-next.com/api/app-bar/) root class we can do the following:

First method (override Material UI classnames):

1 - Add the property classes in the AppBar component:

    <AppBar classes={{root: 'my-root-class'}}

Using auto-generated UTM tagged URLs within Google AdWords along with auto-tagging for Google Analytics

The Challenge

You want to use Google AdWords' auto-tagging for a deep integration with Google Analytics, but you need to use UTM parameters with your other analytics and marketing systems, but don't want to manually tag all of your ads.

The Solution

Within AdWords, you can use ValueTrack and custom parameters along with a tracking template to automatically generate a tagged URL with all of the information you need. A tracking template which populates the query string with campaignid, adgroupid and keywork looks like this:

{lpurl}?campaignid={campaignid}&adgroupid={adgroupid}&term={keyword}

	<img{% if image.title \| kebab != image.slug %} alt="{{ image.title }}"{% endif %} src="{{ image.getUrl('thumb') }}">

	Example Usage:

	{% if entry.images \| length %}
	{% for image in entry.images %}
	<img{% if image.title \| kebab != image.slug %} alt="{{ image.title }}"{% endif %} src="{{ image.getUrl('thumb') }}">
	{% endfor %}
	{% endif %}

	<script>
	// app ID
	var intercomSettings = {
	app_id: "{{IC - Dynamic app ID}}"
	};

	// Verifies and cleans all GTM variables
	function pushGTMVariablesToIntercom(gtmKey, gtmValue) {
	if("{{User - Account - Type}}" != "Guest"){
	if(gtmValue != null && gtmValue != "" && gtmValue != "undefined") {
