How to install OpenCV 4.4.0 with CUDA 11.3 in Ubuntu distro 20.04

First of all install update and upgrade your system:

    sudo apt update

Then, install required libraries:

The use of the I2C DS3231/3232 from Armbian SBC has a few quirks, most tutorials on the internet works but only if you have internet connection.

In cuba we can sometimes use Armbian on devices that are not internet connected, so most tutorial fails and after a power failure or reboot you get a non working system because some apps/soft warns and fail with a "date in the future" message.

I have crafted a way to use it as a real systemd service (yes, it's a legacy service...)

Create a file named: rtc_ds1307 in /etc/init.d/ you can use the command below (root privileges are required)

```
nano /etc/init.d/rtc_ds1307

Emulating a Raspberry Pi with QEMU

Goal: Emulate a Raspberry Pi with QEMU in order to run the Raspbian O/S (based on Debian Linux).

The current setup is not ideal. For one thing, the maximum RAM allowed using the "versatile-pb" firmware is 256 Mb. In addition, only the most basic peripherals, a keyboard and mouse, are supported.

A number of articles have been written on this topic. Most are outdated, and the few recent ones are missing key information.
