Hiellary? That's funny. Don't be afraid, be yourself. If I could
identify you in less than no-time, imagine what 100s of FBI agents
looking through touched-up emails, with like four lines of text each,
max, provided by our beloved TrumpET BlowsJobs to Czar Putin, can do.
By no-time, I mean less than a commercial break, tweet, or news cycle. Combined!
Just imagine 1000s of FBI/NSA/MI5/KGB/CIA/TLA/... agents all snooping
through their @#smartestphones, their iWatches, sipping their sweet
Starbucks lattes, ... all the while pretending to have deciphered
encrypted tweets. In the meantime, winking at the FitBit Girl|Boy...
Perhaps I ought write TV commercials? Maybe I watch too many? Oye ve!

More details please Sergio. I did read a bit regards Super-K.

I've worked with a few server farms, none as vast as NSA might admit having.

That's a very good point, SergioJi. Time makes me forget stuff too.

That's a bold statement. Demonstrate this time-limit.
