Some users are reporting Kernel Panics (Purple Screen) after upgrading to the kernel 7.0.0-28 generic.
To solve this, you need to roll back to an older kernel version. This is accomplished following those steps:
The system should boot as normal.

Some devices, like Bluetooth decoders, have problems with some noise when connected to amplifiers or receivers. Apparently, most of times the issue is a ground loop. That can happen in several devices, like those generic MP3/Bluetooth boards, or those USB powered adapters intended to use in older car units, when the same power supply delivers energy to the amplifier and to the Bluetooth receiver.
One fix is to power the Bluetooth receiver with another power supply. This can work in a car, where instead of using the head unit USB port, you use a cigarette lighter outlet or a power bank. But in the case of a custom speaker like, that is not feasible, or at least impractical.
Enter the DC-DC isolated converters, like the B1212S and others DC-DC isolators. They ta

Pi-Hole's primary function is to be a DNS server with the ability to block domains, usually used for advertising, tracking or other unwanted sites. It also features a built-in DHCP Server.
Usually, your router will also have a built-in DHCP server, pre-configured from factory, and for most users this is perfectly fine. But in some cases you may want to run another DHCP server instead of relying on your router's one. This guide will help you understand how a DHCP server works and how to configure it without disturbing your network.
If you already know the networking basics, you can cut to the chase and read just the configuration part
To Linux evertything is a file.
When you run mkfs.ext4 /dev/sdx or mkfs.ext4 /dev/sdx1 or even mkfs.ext4 /tmp/dummyfile it doesn't care where it is creating your filesystem, it just does.
Let's demonstrate:
dd if=/dev/zero of=testfile bs=1G count=1 oflag=direct status=progress
