Recently, large datacenters in space have been proposed. See Starcloud, Axiom, Thales Alenia, Google Suncatcher, SpaceX. Aside from the launch cost and many other challenges, one principal question is: How doe s GPU, producing significant amounts of heat, get rid of thermal energy? And even the solar panels, with efficiencies of around 30%, turining 70% of all incoming energy into thermal - how do …

Hash-based authentication is an effective way of protecting passwords in software systems. Hashing obscures the original passwords, such that it cannot be recovered in case of a database breach. However, as demonstrated by our paper titled Hash-Based Authentication Revisited in the Age of High-Performance Computers, the practical security depends on which hashing algorithm is used as well as the …
