Technical Perspective: Jupiter Rising
As "Jupiter Rising" makes clear, many of the Internet mechanisms for maintaining large-scale networks are suboptimal when the datacenter is largely homogeneous,...

Jupiter Rising: A Decade of Clos Topologies and Centralized Control in Google's Datacenter Network
We present our approach for overcoming the cost, operational complexity, and limited scale endemic to datacenter networks a decade ago.

Hiding Secrets in Software: A Cryptographic Approach to Program Obfuscation
Can we hide secrets in software? Can we make programs unintelligible while preserving their functionality? Why would we even want to do this? In this article, we...

A Differential Approach to Undefined Behavior Detection
This paper studies undefined behavior arising in systems programming languages such as C/C++. We introduce a new static checker called STACK that precisely identifies...
