They make computers out of software, now

Systems problems are traditionally solved in either hardware or the operating system. Hardware is too expensive to experiment with, while OS-based solutions suffer from the chicken-and-egg problem of moving the world to your improved OS. The virtual machine monitor (VMM) presents a sweet spot between these two extremes. VMM-based solutions can solve a problem in software, once, and yet solve it for all popular operating systems and applications.

I'll be using a new, VMM-based tool called VProbes both to demonstrate the scope of what the VMM can intercept, and and as an example of a feature that would be difficult to implement in other layers. VProbes provides a globally coherent, safe, programmable, interactive window into a running machine, from its CPUs to memory to peripherals.

About Keith Adams

Keith Adams has worked on VMware's virtual machine monitor (VMM) since graduating from Brown University in 2000. At VMware, he's helped to bring support for virtual multiprocessors, hardware CPU and MMU virtualization, and dynamic instrumentation to the VMM.

Secure Browsing with the OP Browser

The modern web browser has evolved from a relatively simple client application designed to display static data into a complex networked operating system tasked with managing many facets of online experience. Support for dynamic content, multimedia data, and third-party plug-ins greatly enriches the browsing experience at the cost of increased complexity of the browser itself, resulting in a plague of security vulnerabilities that provide hackers with easy access to systems. To address the root of this problem, we designed and implemented the OP web browser. We have partitioned the browser into smaller subsystems, isolated each subsystem, and made all communication between subsystems simple and explicit. Finally, we have used formal methods to prove the correctness of the communications between subsystems and the ability to limit the effects of compromised subsystems.

About Sam King

Dr. Samuel T. King is an assistant professor in the Computer Science department at the University of Illinois. His research interests include security, experimental software systems, operating systems, and computer architecture. His current research focuses include defending against malicious hardware, designing and implementing secure web browsers, and applying machine learning to systems problems.

Nerd Life

Sprinkled amongst both Generation X and Generation Y is a curious, new population. The Nerd. The Geek. A group which has spent the last two decades moving from the dark technological fringe to a mainstream demographic.

In this presentation, Rands will first explore the traits of the nerd. How is it that we're able to rampantly consume information? How many people do we really know? Why is it that we must solve puzzles? How is it that we're so good at context switching and so bad at relating to people? And is all this nerdery going to help or hinder my career? It's going to help.

In the second part of this presentation, Rands will explain the role of the nerd in high tech and discuss entry strategies into your favorite company. We're going to talk about simple ways to leverage your nerd tendencies to get you in the right door talking to the right people.

About Rands

Rands is a denizen of Northern California where he's learned the tricks of the trade and earned a living working at a variety of innovative companies including Apple, Netscape Communications, Symantec Corporation, Borland International, and a start-up that blew through a pile of cash before it faded into nothingness.

Late at night, Rands is the author of the technology, management, and nerd weblog where he wonders why managers are so bad at the one thing they should do well, whether nerd traits are a hindrance to a healthy career, and wonders about the best damned gel pen on the Planet Earth. Rands wrote and published a book called "Managing Humans". He's been spotted at various conferences around the world, but mostly he'd like to be holed up in his Cave with an occasional early morning escape to the sweet, sweet surf in Santa Cruz.

Haskell, static typing, type witnesses and darcs

Roundy will introduce the strongly, statically typed language Haskell, and discuss some of the advantages of static typing, particularly in combination with type inference. He will introduce the concept of "type witnesses", a programming trick to enable the compiler to enforce correctness constraints far beyond what is gained from ordinary static typing. Along the way, Roundy will explain how darcs differs from its "competitors", and provide a brief introduction to the patch formalism it uses.

About David Roundy

David is an assistant professor in the Physics Department at Oregon State University, working in the field of Computational Condensed Matter Theory. He created darcs in 2002 after becoming interested in the problem of how to describe and manipulate changes. Around the same time, David learned the Haskell language, and hasn't been the same since. While not working on darcs or physics, David enjoys reading, knitting, crocheting and playing harmonica, but not all at the same time.

A language for the social web: why and how Facebook developed the Facebook Markup Language (FBML)

The Facebook development Platform launched its first API over two years ago, in August 2006. Since its launch it has grown to support over 400,000 external developers developing thousands of social applications and has become the most popular social platform on the web.

This is the story of the technical evolution of Platform, from data assessors to a simple REST API to the full-fledged development platform that it is today. We will discuss the interesting challenges we faced in regards to user privacy, the development of the Facebook Mark-up Language (FBML) as well as the inherent performance issues involved in safeguarding the privacy of over +100 million users and how developers can assist us solving them. We'll also talk about the future of Platform and FBML with Facebook Connect and the rest of the open web.

Computational Linguistics: What is it and what (if any) are its unifying themes?

In a well-known cartoon, Randall Munroe characterizes computational linguistics as a field "so ill-defined that" practitioners "can subscribe to any of dozens of contradictory models and still be taken seriously." As with any humor, there is a serious point here. Indeed, it is often quite hard to see what the substantive claims of computational linguistics are, and how one's model could be falsified (other than by presenting another model that has a lower error rate).

Part of the problem is that a large amount of what counts as computational linguistics is essentially natural language engineering, where the point is simply to find something that works. And part of the problem is a widespread view that has computational linguistics as little more than applied machine learning. Nonetheless, there are models and problems that serve as unifying themes in the field. Among these are the widespread use of finite-state methods, recent work on grammar induction and the growing field of computational modeling of evolutionary language change. Each of these is interesting not only as a computational problem, but also because of the light it may shed on human language.

About Richard Sproat

Richard Sproat is Professor of Linguistics and Electrical & Computer Engineering at the University of Illinois at Urbana-Champaign, and a fulltime faculty member of the Beckman Institute for Advanced Science and Technology. He is also a Visiting Scientist at Google Labs. Prior to coming to UIUC in 2003, Sproat worked for 18 years at AT&T Bell Labs (and its offshoots Lucent Bell Labs and AT&T Labs) on computational linguistics and speech technology. He has authored a number of books, including Morphology and Computation (1992, MIT Press), the 1997 volume (as editor) Multilingual Text-to-Speech Synthesis: The Bell Labs Approach (Springer), A Computational Theory of Writing Systems (2000, Cambridge University Press), and (with Brian Roark) Computational Approaches to Morphology and Syntax (2007, Oxford). His newest book Language, Technology and Society (forthcoming, Oxford), traces the history of language technology, starting with the first such technology, writing, up through modern computer speech and language systems, explains how these systems work, and discusses their social and cultural impact.

Keep Your Shoes On

We are all being terrorized on a daily basis. We make bad decisions in the face of poorly defined but vigorously promulgated fears. And, as developers, we end up creating worse code as a result.

Let's stop being reactive. And let's stop being afraid. And let's create some wonderful, liberated, code.

About Dave Thomas

Straight from the man himself: Dave Thomas is a programmer. He also writes and publishes books.

Latest Developments in Robotic Hardware

Robots have been around for about half a century. Until about a decade ago, robotic arms were strictly confined to caged robotic work cells to protect the safety of people who might otherwise be harmed by high robotic joint torques/forces. The past decade has seen a couple of trends where a cage for safety is no longer practical. The first trend is robotic mobility. It's not practical to build a fixed cage around a mobile robot, considering, for example, Vecna's BEAR robot, designed to rescue wounded soldiers from an active battlefield, or the iRobot Roomba robotic vacuum cleaner.

The second trend is a growing reliance on robots that are necessarily in direct contact with people, such as medical patients during robotically-assisted surgery or rehabilitation. For example, Barrett's robotic WAM arm reduces the invasiveness of knee-implant surgery to improve outcome and shorten hospital recovery time. But robot surgery requires direct physical contact between robot and patient, again challenging the role of a cage. The talk will cover these examples and others that show the recent trends away from traditional fixed robotic work cells in cages. It will also show innovative ways to improve safety as these trends continue.

About William Townsend

Bill Townsend founded Barrett Technology in 1988, credited as maker of the world's "most advanced robotic arm" in the special Millennium Edition of the Guinness Book of World Records. Barrett's WAM arm and BarrettHand products operate in 15 countries around the globe today; and the WAM is the only arm approved by the FDA for force-controlled (haptic) surgery, having performed 100s of successful knee-implant surgeries across the US.

Bill holds engineering PhD and MS degrees from MIT and a BS from Northeastern. He has been awarded 8 US patents and won several professional awards including The Robotic Industries Association's Joseph Engelberger Award in 2003 for pioneering the first haptic robot in the 1980s and best-paper-of-the-year award from UK-journal, Industrial Robot, in 2005.

Studies in the Ballistic Arts

It has been said that close only counts in horseshoes and hand grenades--as long as you count nukes as a kind of hand grenade. But what exactly are you aiming at, and how close is close enough? This talk will be about the past, present, and future of Perl, with a few pointers on how to launch your project, how to steer it while you still can, and when to let it fly off on its own trajectory.

About Larry Wall

Though trained primarily as a linguist, Larry Wall has been working with computers for the last 35 years or so. He is most famous for writing the "patch" program and inventing the Perl programming language, but he prefers to think of himself as a cultural hacker whose vocation in life is to bring a bit of joy into the dreary existence of programmers. Larry is currently employed by Netlogic Microsystems in Mountain View, California.
