Quantum Espresso

I am on the mailing list for The Abdus Salam International Centre for Theoretical Physics, and I recently received an e-mail from that advertises an upcoming conference with a very compelling acronym (ESPRESSO).

Here is an excerpt from the e-mail: In collaboration with the Quantum ESPRESSO Foundation and CECAM, the Abdus Salam International Centre for Theoretical Physics (ICTP), Trieste, Italy, is organizing an Advanced Quantum-ESPRESSO Developers' Training Workshop to be held in Trieste from 19 to 30 January 2015.

What, so classical espresso is no longer good enough?
