Mom Artifacts Server Setup Guide

Share HTML files, visualizations, and interactive demos publicly via Cloudflare Tunnel with live reload support.

What is it?

The artifacts server lets Mom create HTML/JS/CSS files that you can instantly view in a browser, with WebSocket-based live reload for development. Perfect for dashboards, visualizations, prototypes, and interactive demos.

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!

UGREEN DXP4800 Plus TrueNAS Status LED Guide

The following is a quick guide on getting basic status LED functionality working with TrueNAS running on the UGREEN DXP4800 Plus. Theoretically, it should work on all models (with some small revisions to the script), but I only have a DXP4800 Plus. :)

This guide is for cron job that runs a script to update the LEDs every couple minutes, but I'm sure the following can be modified for blinky LEDs as well.

	sudo pacman -S ruby ruby-rdoc gcc make

	gem update --user-install
	gem install jekyll --user-install

	# finally add $HOME/.gem/ruby/2.7.0/bin to your PATH variable

	float D_GGX(float linearRoughness, float NoH, const vec3 h) {
	// Walter et al. 2007, "Microfacet Models for Refraction through Rough Surfaces"

	// In mediump, there are two problems computing 1.0 - NoH^2
	// 1) 1.0 - NoH^2 suffers floating point cancellation when NoH^2 is close to 1 (highlights)
	// 2) NoH doesn't have enough precision around 1.0
	// Both problem can be fixed by computing 1-NoH^2 in highp and providing NoH in highp as well

	// However, we can do better using Lagrange's identity:
