Technical Perspective: An Answer to Fair Division's Most Enigmatic Question
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...
From Communications of the ACM
A Bounded and Envy-Free Cake Cutting Algorithm
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...

Technical Perspective: A Perspective on Pivot Tracing
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...
From Communications of the ACM
Pivot Tracing: Dynamic Causal Monitoring for Distributed Systems
This paper presents Pivot Tracing, a monitoring framework for distributed systems, which addresses the limitations of today's monitoring and diagnosis tools by...

Technical Perspective: Is There a Geek Gene?
"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...
From Communications of the ACM
Evidence That Computer Science Grades Are Not Bimodal
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...
