I thought privacy in China deserved better treatment than was expressed in the foreword of the special section on the China Region (Nov. 2018), that "People in China seem less sensitive about privacy."
Herbert Bruderer explains why the opposite of digital is not analog; Robin K. Hill describes how the challenges of user support are aggravated by indeterminate client responsibility.

The authors of "Distributed Strategies for Computational Sprints" bring the rich theory of allocating scarce resources to the challenge of managing computational sprinting in datacenters.
Thomas F. Wenisch
We describe a computational sprinting architecture in which many, independent chip multiprocessors share a power supply and sprints are constrained by the chips' thermal limits and the rack's power limits.

"Scalable Computation of High-Order Optimization Queries," by Brucato et al., makes a case for marrying the well-established paradigms of constrained optimization (specifically ILP) and traditional SQL querying.
We present a complete system that supports package queries, a new query model that extends traditional database queries to handle complex constraints and preferences over answer sets, allowing the declarative specification and …
