"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...Mark Guzdial From Communications of the ACM | January 2020
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...Elizabeth Patitsas, Jesse Berlin, Michelle Craig, Steve Easterbrook From Communications of the ACM | January 2020
The authors of "Building Certified Concurrent OS Kernels" illustrate that formal verification can scale up to a moderate-size program (6,500 lines of C) that has...Andrew W. Appel From Communications of the ACM | October 2019
In this work, we present CertiKOS, a novel compositional framework for building verified concurrent OS kernels.

We describe a computational sprinting architecture in which many, independent chip multiprocessors share a power supply and sprints are constrained by the chips'...Songchun Fan, Seyed Majid Zahedi, Benjamin C. Lee From Communications of the ACM | February 2019
"Imperfect Forward Secrecy: How Diffie-Hellman Fails in Practice," by David Adrian et al., illustrates the importance of taking preprocessing attacks into account...Dan Boneh From Communications of the ACM | January 2019
We investigate the security of Diffie-Hellman key exchange as used in popular Internet protocols and find it to be less secure than widely believed.
