The Church-Turing Thesis: Logical Limit or Breachable Barrier?
In its original form, the Church-Turing thesis concerned computation as Alan Turing and Alonzo Church used the term in 1936—human computation.
Framework for Implementing a Big Data Ecosystem in Organizations
Featuring the various dimensions of data management, it guides organizations through implementation fundamentals.
Autonomous Tools and Design: A Triple-Loop Approach to Human-Machine Learning
In addition to having a detailed understanding of the artifacts they intend to create, designers need to guide the software tools they use.

Deception, Identity, and Security: The Game Theory of Sybil Attacks
Classical mathematical game theory helps to evolve the emerging logic of identity in the cyber world.
Face2Face: Real-Time Face Capture and Reenactment of RGB Videos
Face2Face is an approach for real-time facial reenactment of a monocular target video sequence (e.g., Youtube video). Our goal is to animate the facial expressions of the target video by a source actor and re-render the manipulated output video in a photo-realistic fashion.
Technical Perspective: Photorealistic Facial Digitization and Manipulation
If facial performance capture is possible for conventional RGB videos in real time, then believable facial expressions can be transferred effortlessly from one person to another in a live-action scenario. This capability is demonstrated by the system of Thies et al. detailed in "Face2Face: Real-Time Face Capture and Reenactment of RGB Videos."

How to Implement Any Concurrent Data Structure
We propose a method called Node Replication (NR) to implement any concurrent data structure.
Bringing the Web Up to Speed with WebAssembly
WebAssembly is the first mainstream language designed from the start with a formal semantics. It not only demonstrates the feasibility of applying formal techniques, but also that they lead to a remarkably clean and simple design.
Promoting Common Sense, Reality, Dependable Engineering
Peter G. Neumann traces a lifetime devoted to identifying computing risks.
Technical Perspective: WebAssembly: A Quiet Revolution of the Web
"Bringing the Web Up to Speed with WebAssembly," by Rossberg et al., gives an overview of the initial design of WebAssembly, a new low-level programming language for Web-based software.
Technical Perspective: Node Replication Divides to Conquer
In "How to Implement Any Concurrent Data Structure," Calciu et al. show that a concurrent data structure can be built automatically and that its performance is actually competitive with state-of-the-art designs for a series of important workloads.
