The envy-free cake-cutting problem stood its ground for two decades, until it was cracked by Aziz and Mackenzie. Their solution is presented in "A Bounded and Envy...Ariel D. Procaccia From Communications of the ACM | April 2020
We report on our algorithm that resolved the well-studied cake cutting problem in which the goal is to find an envy-free allocation of a divisible resource based...Haris Aziz, Simon Mackenzie From Communications of the ACM | April 2020
Instead of handing trace records off to a collector for long-term storage and future processing, the system described in "Pivot Tracing: Dynamic Causal Monitoring...Rebecca Isaacs From Communications of the ACM | March 2020
This paper presents Pivot Tracing, a monitoring framework for distributed systems, which addresses the limitations of today's monitoring and diagnosis tools by...Jonathan Mace, Ryan Roelke, Rodrigo Fonseca From Communications of the ACM | March 2020
"Automating Visual Privacy Protection Using a Smart LED," presents a new technique to address the issue of cameras capturing proprietary or private information—it...Marco Gruteser From Communications of the ACM | February 2020
We introduce LiShield, which automatically protects a physical scene against photographing, by illuminating it with smart LEDs flickering in specialized waveforms...Shilin Zhu, Chi Zhang, Xinyu Zhang From Communications of the ACM | February 2020
"Evidence that Computer Science Grades Are Not Bimodal" uses empirical methods to determine if belief in innate differences may explain why CS teachers see a bimodality...Mark Guzdial From Communications of the ACM | January 2020
There is a common belief that grades in computer science courses are bimodal. We devised a psychology experiment to understand why CS educators hold this belief...Elizabeth Patitsas, Jesse Berlin, Michelle Craig, Steve Easterbrook From Communications of the ACM | January 2020
OpenPiton research is one of the watershed moments in the fundamental shift toward the construction of an open source ecosystem for implementing prototype chips...Michael B. Taylor From Communications of the ACM | December 2019
We present OpenPiton, an open source framework for building scalable architecture research prototypes from one core to 500 million cores.
