Should you drink with your kids?
One night he acquired a bottle of Canadian whiskey, and somehow we persuaded three girls from the tennis camp to join us in his dorm room. Not bothering with glassware, we passed the bottle around until it was empty. I remember eating some watermelon Daly had bought. The evening ended when I regurgitated the whiskey and melon onto one of the girls. Daly and another player on the Razorback golf ...
متن کاملKIDs are non-generic
We prove that the space-time developments of generic solutions of the vacuum constraint Einstein equations do not possess any global or local Killing vectors, when Cauchy data are prescribed on an asymptotically flat Cauchy surface, or on a compact Cauchy surface with mean curvature close to a constant, or for CMC asymptotically hyperbolic initial data sets. More generally, we show that non-exi...
متن کاملWeighing Down "The Unbearable Lightness of PIN Cracking"
Responding to the PIN cracking attacks from Berkman and Ostrovsky (FC 2007), we outline a simple solution called salted-PIN. Instead of sending the regular user PIN, salted-PIN requires an ATM to generate a Transport Final PIN from a user PIN, account number, and a salt value (stored on the bank card) through, e.g., a pseudo-random function. We explore different attacks on this solution, and pr...
متن کاملWeighing Down “The Unbearable Lightness of PIN Cracking” (Extended Version)⋆
Responding to the PIN cracking attacks from Berkman and Ostrovsky (FC 2007), we outline a simple solution called salted-PIN. A randomly generated salt value of adequate length (e.g. 128-bit) is stored on a bank card in plaintext, and in an encrypted form at a verification facility under a bank-chosen salt key. Instead of sending the regular user PIN, salted-PIN requires an ATM to generate a Tra...
متن کاملYou Are What You Eat ?
eat’, both in terms of portions and composition. When we think of this axiom, we conjure visions of ample food portions, rich in energy, high in fat, and associated with persons of equally ample body size proportions and body fat composition. However, these relationships are more complex than they may appear at first glance. The physical, physiological and behavioural manifestation of the compl...
