Verifying Quantitative Reliability For Programs that Execute on Unreliable Hardware
We present Rely, a programming language that enables developers to reason about the quantitative reliability of an application — namely, the probability that it...

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...

Technical Perspective: Combining Logic and Probability
In "Probabilistic Theorem Proving," Gogate and Domingos suggest how PTP could be turned in a fast approximate algorithm by sampling from the set of children of...

Probabilistic Theorem Proving
Many representation schemes combining first-order logic and probability have been proposed in recent years. We propose the first method that has the full power...

Technical Perspective: A Breakthrough in Software Obfuscation
In "Hiding Secrets in Software," Garg et al. construct a "one-way compiler" of the type envisioned by Diffie and Hellman.

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...

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.

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: The State (and Security) of the Bitcoin Economy
"A Fistful of Bitcoins" examines, in the context of Bitcoin, what we could learn by studying the patterns encoded in a complete record of every single financial...

A Fistful of Bitcoins: Characterizing Payments Among Men with No Names
Bitcoin has the unintuitive property that while the ownership of money is implicitly anonymous, its flow is globally visible. In this paper we explore this unique...
