Yo, empty your computer recycle bin / yeah can. That’s where the files are.

Pihole runs on a 10-15 dollar computer (raspberry pi) and blocks anything you want, and is free as in freedom software. It is also zero cost.

I always use this command as $rm -fr and read it as remove, for real

Uncomplicated firewall is a nice frontend for up tables.

Rsync on a scheduled task is dead simple. If your friend can stomach WSL (Windows subsystem for Linux) being on the machine you might try using that. The command is a one liner:

$rsync -r /path/to/source /path/to/backup

and can be automated with cron.

Free software!!

You try’na sell that laptop whenyour get the other one?
