Create virtual audio sinks for pipewire automatically using a system (user) service. With the patchbay software helvum the audio can then be routed/multiplexed for e.g. obs. It per default loops back to the default audio output.

# Create the script to unload the sink automatically
mkdir -p ~/.local/bin
nano ~/.local/bin/unload-virtual-sink.sh
chmod +x ~/.local/bin/unload-virtual-sink.sh
# Create the service

Installed programs:

sudo pacman -S ollama
# AUR
yay -S open-webui
# > provides system service to start on Port 8080

Strings in C

Basics

the C programming language has a set of functions implementing operations on strings (character/byte strings) in its standard library
- e.g. length, copying, concatenation, tokenization, searching
for character strings, the standard library uses the convention that strings are null-terminated:

	CC = gcc
	CFLAGS = -Wall -Wextra -O2

	TARGET = dikstra
	SRCS = main.c
	OBJS = $(SRCS:.c=.o)

	all: $(TARGET)

	$(TARGET): $(OBJS)

	// printf -> print to console
	#include <stdio.h>
	// malloc -> heap memory allocations
	#include <stdlib.h>


	// Data of the Linked List
	typedef struct NodeData {
	int num;
	} NodeData;

	function Invoke-ElevatedCommand {
	param (
	[string]$Command
	)
	$ExpandedCommand = "Write-Host `"Command: `"$Command`"; $Command; Read-Host 'Press Enter to exit window and continue'"
	Write-Host "Invoke-ElevatedCommand: `"$Command`""
	$process = Start-Process powershell.exe -Verb RunAs -ArgumentList "-NoProfile -ExecutionPolicy Bypass -Command `"$ExpandedCommand`"" -PassThru
	$process.WaitForExit()
	}
