**Note:**
 - Normaly cron send task outputs (echo) via mail. As the MTA (Mail Transfert Agent), may not be set up,
the crontab line redirect the outputs into `/dev/null`.
 - Sudo is needed to update the crontab. It also possible to set up your user crontab with `crontab -e`. In this case, remove `username` from the cron entry.
 - The logs can be seen using (with sudo): `sudo grep CRON /var/log/syslog`
