Native Secure Enclave backed ssh keys on MacOS

It turns out that MacOS Tahoe can generate and use secure-enclave backed SSH keys! This replaces projects like https://github.com/maxgoedjen/secretive

There is a shared library /usr/lib/ssh-keychain.dylib that traditionally has been used to add smartcard support to ssh by implementing PKCS11Provider interface. However since recently it also implements SecurityKeyProivder which supports loading keys directly from the secure enclave! SecurityKeyProvider is what is normally used to talk to FIDO2 devices (e.g. libfido2 can be used to talk to your Yubikey). However you can now use it to talk to your Secure Enclave instead!

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.

This is a step-by-step guide to install an OPNsense VM using serial instead of VGA output. It's more resource efficient and allows you to connect to the serial console from Proxmox terminal, allowing things like copying / pasting text.

1. Go to the OPNsense download page and select the correct image:

Architecture: amd64
Image type: serial
Mirror location: something in or close to where you live

This will permanently block revokes and some ppq stuff.
Use this together with the profile to block some domains "without" a DNS.
Even if you don't have the profile, after applying this your device just cannot register revokes anymore. So you'll just not be able to install the app, but you will not get permanently blacklisted.

note this may lead to side effects. I am not sure. However, it does work.

AS ALWAYS, USE AT YOUR OWN RISK.

Basically all u need to do is run these commands one by one in a terminal on a jailbroken device:
