# Hello world!
This is powered by rikidown (see below); some previous text alluded a different software I was considering that ultimately got dropped because it was not using propert Markdown format. This seems to be working much better.

[skubelb](skubelb.md) is a simple kubernetes load balancer/proxy tool; the intended use case is to provide ingress from a free-tier GCP VM to hosts that live at dynamic IPs. Originally, this was used to expose a GKE instance hosted on spot VMs to the internet, and deal with the constantly changing IPs.

I acquired a used server for a very reasonable cost; it has 80x3.0ghz ARM cores, 128 GiB of RAM, and uses 70w of power. Power where I live is super expensive, so I'm very excited to have this beast available for minimal power cost.

The Git repo for my FluxCD configuration is not public because I'm not confident that I've correctly removed all private keys from it (notably, the keys to access the kubernetes dashboard). In principle it should still be fine because access to the k3s control plane is restricted to my local network, but all the same... I don't trust you.

## Large language model (LLM)
LLM models are tensor networks that an activation matrix activates, resulting in an output matrix.

The most practical, and common approach, is to change the text we are asking the model to
autocomplete. This can come in many forms, but I see there as being N primary ways:
1. Add more data to the request. This can include copy-pasting stuff, using 'retrieval augmentation'
to pull related information from dataset (or from a search engine)
2. Allow loading more context as requested by the model; this can include tool-calling
1. Add more data to the request. This can include copy-pasting stuff, using 'retrieval augmentation' (also known as Retrieval-Augmented Generation or RAG) to pull related information from a dataset (or from a search engine). Basically, before sending the prompt to the LLM, the client does a search to find additional context. There are lots of tools for doing this, but the most popular seem to be from the AI community, and work by converting the user input to a 'vector' of NLP tokens, using a specialized 'vector database' to find other 'chunks' of related inputs, then add those to the message before sending it to the LLM.
2. Allow loading more context as requested by the model; this can include tool-calling. This is a super powerful capability; developers generally implement this by telling the LLM how to structure its output to make tool calls, then attempting to parse the LLMs output to detect tool calls, run the tools, and append the result to the message going into the LLM.
Everything is one of these 2 techniques. The vast majority of systems that are being advertised are
effectively just storing context (or summarized context), adding it to your prompt, and stripping it out

This is a very simple Markdown-wiki renderer. I use it with Obsidian, because it has a fancy UI and I like shiny things, BUT, Obsidian does not seem to be open source. And this makes me sad.
Irregardless; the tool is simple, and not super optimal. In particular, it will render the markdown page for every single request, which is fairly expensive. It might be better to render the pages when the git repo is updated/cloned, but I'm lazy.

There are dangers to alcohol; it is an addictive substances, for me at least, because it is fun. It helps me relax, forget about the daily worries, and even feel comfortable expressing myself on this forum when I normally wouldn't. Balancing the expression of "I'm comfortable saying this AND its appropriate", and saying or doing absolutely terrible things is a challenge. If you catch yourself apologizing for your behavior after a few drinks, consider whether you are having trouble acting correctly under the influence.
