Abstract
Many allocation decisions require costs today (or, at least, beginning today ) with benefits extending into the distant future, affecting lives not yet in existence. The leading example today is policy to meet anthropogenic climate change, but that problem is by no means unique. How do we think about the balancing of values? To some extent, the questions have to do with empirical regularities, but to a major extent, they depend on value judgments about our obligations to future generations. The decisions are further complicated by uncertainties about the future.

Abstract
How can you know when someone is bluffing? Paying attention? Genuinely interested? The answer is that subtle patterns in how we interact with other people reveal our attitudes toward them. These predictive patterns seem to be biologically based "honest signals," evolved from ancient primate signaling mechanisms, and we find that they are major factors in human decision making in situations ranging from job interviews to first dates. By analyzing these signals using data from mobile phones, electronic ID badges, or digital media, we can create a "gods eye" view of how the people in organizations interact, and even `see' the rhythms of interaction for everyone in a city.

Abstract
Building large scale distributed application is hard; debugging and profiling them is even harder. Today, almost every web request involves an application running distributedly on many machines in one or more data centers. These applications need to run 24x7, handle inputs that vary by multiple orders of magnitude, and seamlessly accommodate hardware and software upgrades. To successfully build and run such applications it is critical to model and understand their behaviors. In this talk, I will discuss some of our initial efforts to build tools that provide a comprehensive understanding of the behavior of distributed applications, and allow careful offline analysis by faithfully reproducing race conditions and non-deterministic failures that occurred during the original execution.

Abstract
My vision for the 21st Century: Computational thinking will be a fundamental skill used by everyone in the world. To reading, writing, and arithmetic, let's add computational thinking to every child's analytical ability. Computational thinking has already influenced other disciplines, from the sciences to the arts. The new NSF Cyber-enabled Discovery and Innovation initiative in a nutshell is computational thinking for science and engineering. Realizing this vision gives the field of computing both exciting research opportunities and novel educational challenges. The field of computing is driven by technology innovation, societal demands, and scientific questions. We are often too easily swept up with the rapid progress in technology and the surprising uses by society of our technology, that we forget about the science that underlies our field. In thinking about computing, I have started a list of "Deep Questions in Computing,” with the hope of encouraging the community to think about the scientific drivers of our field.
