'Securely' wiping drives: My method of choice is to simply dd over the drive.

sudo dd if=/dev/zero of=/dev/sdX status=progress && sudo dd if=/dev/random of=/dev/sdX status=progress && sudo dd if=/dev/zero of=/dev/sdX status=progress && sudo dd if=/dev/random of=/dev/sdX status=progress

Quite simply, it zeros the whole drive followed by writing random gobbledygook, then repeating the process. This ensures the drive is as scrambled as reasonable to prevent possible recovery of any kind (short of using an explosive device).

NOTE: For SSDs you would only need to write /dev/random twice as the write process on SSD devices is proceeded by a zero signal prior to performing the write. Therefore:

sudo dd if=/dev/random of=/dev/sdX status=progress && sudo dd if=/dev/random of=/dev/sdX status=progress

produces the same result. Writing zeros only wears the drive that little bit faster.

How about `sudo apt-get install love`?

I'm trying to connect to a VPN server at home but when I open the OpenVPN app on my phone the status hangs at "Looking up DNS name". If I enter the IP address directly into the app, it connects. I have checked and my IP is updating in DuckDNS ok. Why wouldn't DuckDNS not pass on the IP?

Is there an ISO for Ubuntu Mate 14.04 for PPC? I have been having issues with 16.04 that seem to be related to the graphics driver. My research suggests the old Radeon driver hasn't been updated and may not as it has been made obsolete (or something like that) . I'm hoping I can get 14.04 to run better using the older driver.
The machine is my son's MacBook G4 with a PowerPC processor and a Radeon 9550 gpu.

I have just finished setting up an OpenVPN server and have setup DuckDNS to manage my dynamic IP from my ISP. However my phone cannot resolve the domain name. Using my current IP works, so it isn't a problem with my port forwarding or other settings. The DuckDNS home page has the correct current IP, so the IP updating is working ok.
