Evolutionary Programming Converts Darwinism Into Algorithms
Evolutionary computation strategies include a multitude of biologically inspired algorithms for optimizing problems, often those with too many variables to compare all possible scenarios.
AI Tutoring: Genius on My Shoulder
Students are being given access to an incredibly smart digital friend with unlimited patience, programmed to sense the best way to impart knowledge.
Computing Is the Secret Ingredient (well, Not So Secret)
Computer science is both a powerful enabler of rapid advances in all intellectual fields and a disruptor driving furious revolutions in commerce and society worldwide.
Cybersecurity, Nuclear Security, Alan Turing, and Illogical Logic
Cyber deterrence, like nuclear deterrence, depends on our adversaries being rational enough to be deterred by our threats but us not by theirs.
Technology-Driven Changes in Work and Employment
Even when surrounded by ubiquitous computing, humans should be encouraged to do what they do better than machines.
Energy Efficiency: A New Concern For Application Software Developers
Development of energy-efficient software is hindered by a lack of knowledge and a lack of tools.
A Theory Of Pricing Private Data
We describe the foundations of a market in which those seeking access to data must pay for it and individuals are compensated for the loss of privacy they may suffer.
Automatically Accelerating Non-Numerical Programs By Architecture-Compiler Co-Design
HELIX-RC is a compiler/microprocessor co-design that opens loops to parallelization by decoupling communication from thread execution in conventional multicore architectures.
Technical Perspective: A Simple, Elegant Approach to Non-Numeric Parallelization
"Automatically Accelerating Non-Numerical Programs by Architecture-Compiler Co-Design," by Simone Campanoni, et al., proposes a modest hardware extension to support a new parallel execution model for small, non-numeric loops.
Technical Perspective: Pricing Information (and Its Implications)
"A Theory of Pricing Private Data," by Chao Li, et al., introduces a fascinating and complicated issue that arises on the buy-side of the market when buyers are interested in multiple linear functions of the same dataset.
The 37% rule is rarely applicable in real-world situations. It is certainly entirely wrong-headed as advice for getting married.

Cardboard surrounds and protects stuff as it crosses boundaries.
Engineering has been marginalized by the unhealthy belief that engineering is the application of science.
Consumers are sampling virtual reality systems and software, without needing to buy them.
Our behaviors often seem to mimic the procedures that we induce in computers. What questions does that raise?
"When Does Law Enforcement's Demand to Read Your Data Become a Demand to Read Your Mind?" (Sept. 2017) was an important contribution to the ongoing debate over electronic backdoors. I would like to outline several key aspects of that debate that also need to be addressed.
