Debian 13 Trixie with BTRFS
Introduction
I am installing Debian 13 Trixie (recently released as Debian Stable) on a Virtual machine (VM) using the B-TRee File System (BTRFS). The Debian installer supports installing a BTRFS volume to a partition, and creating a single sub volume within. With the terminal I will be modifying a BTRFS volume that spans multiple drives, and contains multiple sub volumes.
A portion of this work will need to be done outside the Debian installer. The most common methods involve either mid install break out or post install. I have not found any information on pre install procedures for this. Looking at the way the Debian installer works this may not be possible.
In this article I will be doing a post install file system modification. To me this seems the most straight forward and easy to understand method.

Basic Alternating Current (AC) Circuit
What is Alternating Current, and why do we need it?
Lets discuss some of the fundamentals of Alternating Current or AC. Historically Electrical usage was originally all Direct Current or DC. In fact most of our devices still use DC internally. However AC is much more efficient than DC for transmitting power over great distances. This is why we get AC delivered to an outlet and our device converts it to DC.
DC, in general is much easier, and less complex to use than AC, as alternating the flow of current can change the characteristics of even simple circuits. I want to look at some of the basic fundamentals of AC as they apply to a simple electric circuits.
