if you're using something else, you probably know what to do 😉

Windows 10 Pro

Windows 10 Pro ISO

Create a fresh Windows 10 Pro ISO file with Microsofts Media Creation Tool. (I created a Windows 10 Pro 64 bit German ISO image)

Save the created image on your SmartOS global zone.

cp ... /zones/Windows10_64de.iso

AptX & AAC on MacOS Bluetooth

AptX works on Catalina (10.15.4), tested with the Sony WH-1000XM3.

Run the following commands in terminal: (Bluetooth Explorer is no longer needed)

sudo defaults write bluetoothaudiod "Enable AptX codec" -bool true
sudo defaults write bluetoothaudiod "Enable AAC codec" -bool true

Reboot both your system and headphones.

If you're using a high-end bluetooth headset on your Macbook Pro it's likely your mac is using an audio codec which favors battery efficiency over high quality. This results in a drastic degradation of sound, the SBC codec is the likely culprit, read more about it here.

Find out what codec you're using

Play a song on your headphones
Option (⌥) click the Bluetooth button at the top of your screen
If you're using AAC or aptX, you can stop here—those are the highest quality codecs.

Change your codec to AAC or aptX

Low-Latency Live Streaming for your Desktop using ffmpeg and netcat

Preamble:

In this post I will explore how to stream a video and audio capture from one computer to another using ffmpeg and netcat, with a latency below 100ms, which is good enough for presentations and general purpose remote display tasks on a local network.

The problem:

	# Arch linux samba setup guid

	1. sudo pacman -Sy samba
	2. copy attached file at /etc/samba/smb.conf

	3. Edit config file
	a. In global section add following lines
	# ios based config
	fruit:nfs_aces = no
	fruit:aapl = yes
