Looking to create a Software RAID 1 setup for your 2-disk server on Ubuntu Server 20.04?

Let's start with the basics: the official guide by Ubuntu (https://ubuntu.com/server/docs/install/storage) is outdated/wrong. And as of March 2021 it's possible that there's a bug as well with how the bios_grub partitions are created when using multiple disks.

Now on to the solution:

Select "Custom storage layout" when you reach the storage configuration step of the installer.
If the disks have existing partitions, click on each disk under AVAILABLE DEVICES and then select REFORMAT. This will (temporarily) wipe out the partitions.

Send Raw Bytes to Bluetooth SPP with bluetoothctl

bluetoothctl gatt.list-attributes
bluetoothctl gatt.select-attributes <spp - attributes>
bluetoothctl gatt.write "0xhh 0xhh ..."

Using interactive cli

The basic concept of UN-ENCRYPTED VPN is to route all network packets to the client's TUN interface, where the VPN Client Sofware will read the packets from the TUN interface and write them into a buffer which then will be sent via TCP/UDP connection to the VPN Server. The VPN Server Software writes all data to the server's TUN interface so that it can go to the intended recipient. At this point there are important settings a server must be configured with.

# Server side configuration
sysctl -w net.ipv4.ip_forward=1
iptables -t filter -A FORWARD -j ACCEPT
iptables -t nat -A POSTROUTING -j MASQUERADE -s <TUN_IP/MASK>

Step-by-Step GCC

main.c

#include<stdio.h>

int main(int argc, char *argv[])
{
  printf("Hello, World !");
  return 0;
}
