Výměna pronajatého ONT (Comtrend) za FS XGS-SFP-ONT-MAC-I zastrčený přímo do SFP+ portu routeru. Vyřešeno v červenci 2026 — od té doby v provozu. Všechno níže je ověřené na reálné lince O2/CETIN: výstupy v tomto textu jsou skutečné, ne ilustrační (jediné dvě odvozené věci — baby-jumbo MTU a průběh VEIP setu v 1U — jsou v textu výslovně označené).

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.
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.
Thought I should post my guide on how to do this, as I've struggled with this for quite some time now. I wanted something to bypass the NAT/router as I did not have the option of port-forwarding. I will also be moving quite some in the upcoming year, so dynamic IP was almost a given. And obviously I wanted it to be cheap. This does it all.
This is free, no port-forwarding required and no static IP required. Wildcard domain and SSL certificate supported. It works with Cloudflare tunnels, Cloudflare DNS, Nginx Proxy Manager and obviously TrueNAS SCALE.
I am not a professional, if you see a flaw in this design, please let me know!

I've recently joined Amazon Dublin from India and got opportunities to interview with Meta London, Zalando Berlin & some other companies. I extensively researched about companies hiring internationally which support visa & relocation for Tech roles. So sharing list of companies:
Do consider to STAR, if it helped you.
