While staring in wonder at some of the incredible images, it's natural to ask how such feats are possible. "GAN Dissection: Visualizing and Understanding Generative Adversarial Networks" gives us a look under the hood to see what kinds of things are being learned by GAN units, and how manipulating those units can affect the generated images. February saw the 16th edition of the Usenix Symposium on Networked Systems Design and Implementation. Kalia et al. blew me away with their work on fast RPCs (remote procedure calls) in the datacenter. Through a carefully considered design, they show that RPC performance with commodity CPUs and standard lossy Ethernet can be competitive with specialized systems based on FPGAs (field-programmable gate arrays), programmable switches, and RDMA (remote direct memory access). It's a fabulous reminder to ensure we're making the most of what we already have before leaping to more expensive solutions.

First, we need to consider where the data is being processed and stored and what the privacy and systems implications of these policies are. Second, we need to develop systems that generate actionable insights from this diverse, hard-to-interpret data for non-tech users. Solving these challenges will allow IoT systems to deliver maximum value to end users.

Miners go to extreme lengths to maximize their revenue and often find creative ways to do so that are sometimes at odds with the protocol. Cryptocurrency protocols should be placed on stronger foundations of incentives. There are many areas left to improve, ranging from the very basics of mining rewards and how they interact with the consensus mechanism, through the rewards in mining pools, and all the way to the transaction fee market itself.

While messaging protocols such as Signal provide privacy guarantees, Albert's selected research papers illustrate what is possible at the cutting edge: more transparent endpoint authentication, better protection of communication metadata, and anonymous broadcasting. These papers marry state-of-the-art cryptography with practical, privacy-preserving protocols, providing a glimpse of what we might expect from tomorrow's secure messaging systems. Second, James Wilcox takes us on a tour of recent advances in verified systems design. It's now possible to build end-to-end verified compilers, operating systems, and distributed systems that are <i>provably</i> correct with respect to well-defined specifications, providing high assurance of well-defined, well-behaved code. Because these system components interact with low-level hardware like the instruction set architecture and external networks, each paper introduces new techniques to balance the tension between formal correctness and practical applicability. As programming language techniques advance and more of the modern computing stack continues to crystallize, expect these advances to make their way into production systems.

These changes (a.k.a. digital) will profoundly change how enterprises operate. Software is at the heart of this digital world, but the software toolsets and languages were conceived for the host-based era. The issues that already plague software practice (such as high defects, poor software productivity, information vulnerability, poor software project success rates, etc.) will be more profound with such an approach. It is time for software to be made simpler, secure, and reliable.

It's a giant problem space, but the necessary tools and technology are here today. We just need to define the problem a little better. Networks Wed, 30 Aug 2017 16:07:29 GMT Jacob Loveless 3136953
