Incremental, Iterative Data Processing with Timely Dataflow
We describe the timely dataflow model for distributed computation and its implementation in the Naiad system.

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.

Technical Perspective: Why Didn't I Think of That?
Until now, the database in a Web application has been treated as a global variable, accessible to all. In "Ur/Web: A Simple Model for Programming the Web," Adam...

Enhancing Symbolic Execution with Veritesting
In this article, we present a new technique for generating formulas called veritesting that alternates between static symbolic execution (SSE) and dynamic symbolic...

Technical Perspective: Software Is Natural
"On the Naturalness of Software" by Hindle et al. takes an entirely new approach to providing tools to help build software.
From Communications of the ACM
On the Naturalness of Software
We begin with the conjecture that most software is natural, with all the attendant constraints and limitations — and thus, like natural language, it is also likely...

Technical Perspective: Program Synthesis Using Stochastic Techniques
The authors of "Stochastic Program Optimization" have developed a stochastic search technique and applied it to program optimization.
From Communications of the ACM
Stochastic Program Optimization
By encoding constraints of transformation correctness as terms in a cost function, and using a Markov Chain Monte Carlo sampler to explore the space of all possible...

Technical Perspective: Treating Networks Like Programs
"Software Dataplane Verification" takes existing static checking of networks to a new level by checking the real code in the forwarding path of a Click router using...
From Communications of the ACM
Software Dataplane Verification
We present the result of working iteratively on two tasks: designing a domain-specific verification tool for packet-processing software, while trying to identify...
