Technical Perspective: On Heartbleed: A Hard Beginnyng Makth a Good Endyng

When a serious security vulnerability is discovered in the SSL/TLS protocol, one would naturally expect a rapid response. "Analysis of SSL Certificate Reissues and Revocations in the Wake of Heartbleed," by Zhang et al., paints…

Time-Inconsistent Planning: A Computational Problem in Behavioral Economics

Time-Inconsistent Planning

We propose a graph-theoretic model of tasks and goals, in which dependencies among actions are represented by a directed graph, and a time-inconsistent agent constructs a path through this graph.

Technical Perspective: A Graph-Theoretic Framework Traces Task Planning

In "Time-Inconsistent Planning: A Computational Problem in Behavioral Economics," Kleinberg and Oren describe a graph-theoretic framework for task planning with quasi-hyperbolic discounting.

Analysis of SSL Certificate Reissues and Revocations in the Wake of Heartbleed

Analysis of SSL Certificate Reissues and Revocations in the Wake of Heartbleed

We use Heartbleed, a widespread OpenSSL vulnerability from 2014, as a natural experiment to determine whether administrators are properly managing their X.509 certificates.
