Divination by Program Committee

Divination is the practice of an occultic ritual as an aid in decision making. Developments in mathematics and in computer science in the 20th century shed new light on the power of divination.
DEPARTMENT: Letters to the editor

Computational Thinking Is Not Necessarily Computational

I applaud Peter J. Denning's "Remaining Trouble Spots with Computational Thinking" (June 2017), especially for pointing out the subject itself is often characterized by "vague definitions and unsubstantiated claims."

Technical Perspective: A Gloomy Look at the Integrity of Hardware

"Exploiting the Analog Properties of Digital Circuits for Malicious Hardware," by Kaiyuan Yang, et al., assumes semiconductor foundries (and others in chip fabrication) can be malicious, modifying designs to produce devices that …

Exploiting the Analog Properties of Digital Circuits for Malicious Hardware

We show how a fabrication-time attacker can leverage analog circuits to create a hardware attack that is small and stealthy.

Technical Perspective: Humans and Computers Working Together on Hard Tasks

"Scribe," by Walter S. Lasecki, et al., is one of the first in a recent set of crowdsourcing papers that demonstrated how human workers can collaborate with computing systems to accomplish a real-time task that is difficult for …

Scribe: Deep Integration of Human and Machine Intelligence to Caption Speech in Real Time

We discuss how our Scribe system combines human labor and machine intelligence in real time to reliably convert speech to text with less than 4s latency.
