TL;DR: In this paper, the authors proposed a method to identify one or more events associated with users on a social graph, by generating at least one directed acyclic graph (DAG), where each node on the DAG represents a node in the social graph where an event of the type occurs and each edge on the edge represents a propagation of the event from a first node of the edge to a second node of an edge.

TL;DR: In this article, the authors discuss CUECARD, the program that won the 2008 Computer Olympiad computational pool tournament, and isolate the factors that contributed to the performance so that the lessons can be transferred to other, similar domains.

TL;DR: In this paper, the compromised password mitigation module comprises a compromised password collection module, compromised password storing module, a logging module, account protection module and user database, which is used when evaluating access to determine whether a submitted password matches both a compromised passwords hash and an actual password hash.

TL;DR: It is shown that useful choice rules satisfying both notions of non-manipulability, and for the transferable utility case provide bounds on the level of Condorcet consistency.
