yt-sum

Summarise YouTube videos from the command line using a local LLM via Ollama.

Fetches transcripts with ytx-cli (no API key required).
Runs summarisation against any Ollama model (Gemma 4, Qwen 3.6, Llama, etc.).
Automatic map/reduce chunking for videos that exceed the model's context window.
Split map + reduce models — use a tiny fast model per chunk, a bigger one for final synthesis.
Throttled parallel map and intermediate-reduce calls.
Hierarchical reduce — iteratively collapses map outputs that don't fit in one reduce call, up to 4 levels deep.

Meta Prompting

In the Generative AI Age your ability to generate prompts is your ability to generate results.

Guide

Claude 3.5 Sonnet and o1 series models are recommended for meta prompting.

Replace {{user-input}} with your own input to generate prompts.

Use mp_*.txt as example user-inputs to see how to generate high quality prompts.

Hardening the USB Armory

As a good crypto nerd, I usually use an entirely encrypted linux FS: / but also /boot using grub LUKS support. It's a good setup but it's not perfect, the BIOS and the bootloader are not protected.

I recently got a USBArmory and I wanted to apply the same (or a better) setup.

I found some useful links but no clear howto. So this is my setup.

via (https://www.linux.com/learn/tutorials/442438-vim-tips-folding-fun)

zf#j creates a fold from the cursor down # lines.
zf/string creates a fold from the cursor to string .
zj moves the cursor to the next fold.
zk moves the cursor to the previous fold.
zo opens a fold at the cursor.
zO opens all folds at the cursor.
zm increases the foldlevel by one.
zM closes all open folds.
