The Machineries of Doubt & Disinformation: Cigarettes, Climate & Other Electronic Confusions [EE380 Computer Systems Colloquium]

Topic: 
The Machineries of Doubt & Disinformation: Cigarettes, Climate & Other Electronic Confusions
Abstract / Description: 

The tobacco industry has long employed the best marketing techniques and adopted the latest technologies for disinformation. The fossil energy industries have employed similar tactics and technologies. For both, the Internet has proved a fertile ground and by now, similar tactics have gained force in politics.

For example, 2009 "Climategate" theft and use of emails against climate scientists seems a precursor of recent Russian efforts in American & French elections.

This talk uses insights from the well-documented history of tobacco and fossil disinformation machinery to anticipate further attacks on science and political processes, including thoughts about the challenges of informed skepticism in the world of Internet, Twitter and Facebook and electronic cigarettes that monitor and control usage, and may report back to the vendor.

How to Design Addictive Games [EE380 Computer Systems]

Topic: 
How to Design Addictive Games
Abstract / Description: 

A great game seduces its player into flow state. Since we know a lot about what flow state is and what it requires, you might imagine that game's design to be a lot of work, but not mysterious. Yet 99% of all games fail. The vast majority of game designers have never designed an addictive game. In HCI research, games are analyzed based on flow state properties but that's descriptive, not prescriptive. Designing such games remains mystical. Like other performing arts, game design needs accident, luck, inspiration, perspiration, and knowledge. I would like to justify my being invited to talk so on top of the skeleton of flow, I will add some meat that you would not likely hear from anyone else. I will talk about what I learned playtesting my own work and what I was taught by great game designers, in creating games that were indeed addictive. As such, this will be a very idiosyncratic and personal introduction to the art of designing irresistible engagement.

Computers, Programming, Addiction, False News, Alternative Facts [EE380 Computer Systems]

Topic: 
Computers, Programming, Addiction, False News, Alternative Facts
Abstract / Description: 

Today's Internet is powerful and seductive. It's burrowed itself into the way we think, feel, and respond. We have come to depend upon the availability of organized, accessible, searchable information. But with the positive effects, there are negative factors as well, with unforeseen consequences, that change the very way we experience the world.

Archiving and indexing all of the world's information has changed the way we think, but it has its limitations. Very low cost communication and publication have both positive and negative effects. Interactive environments are compelling and sometimes addictive. Social interactions on the Internet are different than they are in "real life". Truth seems less important than it once was.

This talk will identify and explore a few of these issues. Interactive discussion will be encouraged.

Software-centric Visible Light Communication for the Internet of Things [EE380 Computer Systems]

Topic: 
Software-centric Visible Light Communication for the Internet of Things
Abstract / Description: 

Visible Light Communication (VLC) based on LEDs for light emission and reception can be realized using simple components, delegating many of the "hard" problems to software. We present a software-centric approach that supports networking a wide range of devices -- devices that include only simple single LEDs (such as wearables, toys, consumer electronics) as well as LED light bulbs that run Linux and provide a VLC communication fabric (room-area network). One of the benefits of the software-centric approach is easy integration into distributed applications - a necessary condition for a pervasive communication infrastructure for the Internet of Things that requires a wide range of services (localization, time, authentication, etc).

Joint work with Stefan Mangold (Lovefield Wireless, Inc.) and Stefan Schmid (ETH Zurich).

PyWren - pushing microservices to teraflops [EE380 Computer Systems]

Topic: 
PyWren - pushing microservices to teraflops
Abstract / Description: 

Much of cloud computing infrastructure remains hard to use, in spite of decades of both academic research and commercialization. Fortunately, recent technologies developed for web services and internet startups can be repurposed to enable a much lower-friction scalable cloud experience. Our goal is making the power, elasticity, and dynamism of commercial cloud services like Amazon's EC2 accessible to busy applied physicists, electrical engineers, and data scientists, as well as a compelling new capability over Matlab, hopefully encouraging migration. We built PyWren, a transparent distributed execution engine on top of AWS Lambda, which hopefully simplifies many scale-out use cases for data science and computational imaging. We will demo applications built on our framework and seek user input into next directions.

Joint work with Shivaram Venkataraman, Qifan Pu, Ion Stoica, and Ben Recht.

Living in Information Everywhere [EE380 Computer Systems Colloquium]

Topic: 
Living in Information Everywhere
Abstract / Description: 

The term cloud computing increasingly describes not just the technology of large networked data centers, but is a proxy term for the unification of smartphones, apps, IoT, Big Data, and Artificial Intelligence -- in effect, the deployment of computational intelligence to virtually every point on the planet. One may view this as a fulfillment of Moore's Law, or the start of decades-long project that is likely to reshape civilization. As someone who both covers this topic and has been profoundly affected by it, I will speak about the technology, and what historical parallels tell us about the likely impact.

Neuromorphic Chips: Addressing the Nanostransistor Challenge by Combining Analog Computation with Digital Communication [EE380 Computer Systems Colloquium]

Topic: 
Neuromorphic Chips: Addressing the Nanostransistor Challenge by Combining Analog Computation with Digital Communication
Abstract / Description: 

As transistors shrink to nanoscale dimensions, trapped electrons--blocking "lanes" of electron traffic--are making it difficult for digital computers to work. In stark contrast, the brain works fine with single-lane nanoscale devices that are intermittently blocked (ion channels). Conjecturing that it achieves error-tolerance by combining analog dendritic computation with digital axonal communication, neuromorphic engineers (neuromorphs) began emulating dendrites with subthreshold analog circuits and axons with asynchronous digital circuits in the mid-1980s. Three decades in, they achieved a consequential scale with Neurogrid, the first neuromorphic system with billions of synaptic connections. Neuromorphs then tackled the challenge of mapping arbitrary computations onto neuromorphic chips in a manner robust to lanes intermittently--or even permanently--blocked by trapped electrons. Having demonstrated scalability and programmability, they now seek to encode continuous signals with spike trains in a manner that promises greater energy efficiency than all-analog or all-digital computing across a five-decade precision range.
