My fingerprint: F3CE E9F3 1BDF 1268 DBF2  32C7 FB44 2070 C024 2E80

Actions:
  Principle: I didn't want to destroy any hardware because I'm not rich.

  Environment: a small room, where I was alone.

  Preparation: My host computer is a MacBook Pro with macOS 10.13.3. I 
installed VirtualBox (www.virtualbox.org). I downloaded a Ubuntu desktop iso 
image from https://www.ubuntu.com and I created a VM in VirtualBox. I enabled 
"Disk Image Encryption" in the VM. I tured off its Bluetooth adapter. In the 
beginning I left the network adapter connected to the host's. After installing 
Ubuntu in the VM, I installed curl.
  
  Other installs in the guest VM (still dependent on network adapter connected 
to the host's at this stage):
   curl in shell
   Rust from https://www.rust-lang.org/ 
   Powers of Tau source from https://github.com/ebfull/powersoftau  

  Ceremonial step:
   cargo run --release --bin compute   # with network connection on
  At the step where the program asks for keyboard input, Gustavo turned the 
VM (guest) network connection off and the host connection off also. 

   The input may have included counts of letters in words I read today, words I 
read today in English and in Russian, and people that I counted today. It may 
have included names of people. I also may have played a song by Beethoven in 
the keyboard as if it were a piano. And I may have played the fingering of a 
Bach violin concerto as if the keyboard were a violin fingerboard. And I may 
have typed random keys in the keyboard.

   At the end of the computation (it tooks almost 3 hours), I copied to 
clipboard the BLAKE2b hash of the response file. Then I rebooted the VM. After 
that, created a volume share between guest and host. I then saved the response 
file in the host computer. Then I deleted the VM, including all of its 
(encrypted) files. After, around 7 pm UTC-6 I uploaded the response file to the 
URL given to me by email ( it began with 
https://s3-us-west-2.amazonaws.com/powersoftau/p6RZ )
