Node.js

Q1: What do you mean by Asynchronous API? ☆☆

Answer: All APIs of Node.js library are aynchronous that is non-blocking. It essentially means a Node.js based server never waits for a API to return data. Server moves to next API after calling it and a notification mechanism of Events of Node.js helps server to get response from the previous API call.

How to set up PulseAudio over Network

PulseAudio actually has great networking capabilities. Especially when combined with Avahi/Zeroconf it is especially easy to set up, though technically it should also be possible without.

Setting up the server

Open /etc/pulseaudio/default.pa
At the end of the file, add load-module module-native-protocol-tcp auth-ip-acl=127.0.0.1;192.168.254.0/24 auth-anonymous=1 to activate networked audio from 192.168.254.0-255 without needing authentication.
Kill pulseaudio, it should be auto-restarted, or restart your login session to activate the changes. You should now be able to set PULSE_SERVER=192.168.254.XXX and have the remote audio working! If not check the firewall settings, PulseAudio seems to open a random port by default.

Setting up automatic configuration and discovery

On both the server and client, install pulseaudio-module-zeroconf and avahi, then after installing make sure Avahi always runs by running systemctl enable --now avahi-daemon

Best practices for PCB Design

Schematics

Power symbols should point upwards
Ground symbols should point downards
Sections should be labeled
Nets should generally not cross
Nets should be labeled
Either global or regular labels are fine
