+  <abstract>
+    <p>
+      Veteran Mozilla engineer Ehsan Akhgari presents a talk on the internals of web browsers.
+      The material ranges from the fundamentals of content rendering to the latest innovations in browser design.
+    </p>
+    <p>
+      Web browsers have evolved. From their humble beginnings as simple HTML
+      rendering engines they have grown and evolved into rich application
+      platforms. This talk will start with the fundamentals: how a browser
+      creates an on-screen representation of the resources downloaded from
+      the network. (Boring, right? But we have to start somewhere.) From
+      there we'll get into the really exciting stuff: the latest innovations
+      in Web browsers and how those innovations enable — even encourage —
+      developers to build more complex applications than ever before. You'll
+      see real-world examples of people building technologies on top of
+      these "simple rendering engines" that seemed impossible a short time
+      ago.

+  <abstract>
+    <p>
+      GPGPU (general purpose graphics processing unit) computing is an
+      expanding area of interest, with applications in physics, chemistry,
+      applied math, finance, and other fields. nVidia has created an
+      architecture named CUDA to allow programmers to use graphics cards
+      without having to write PTX assembly or understand OpenGL. CUDA is
+      designed to allow for high-performance parallel computation controlled
+      from the CPU while granting the user fine control over the behaviour
+      and performance of the device.
+    </p>
+    <p>
+      In this talk, I'll discuss the basics of nVidia's CUDA architecture
+      (with most emphasis on the CUDA C extensions), the GPGPU programming
+      environment, optimizing code written for the graphics card, algorithms
+      with noteworthy performance on GPU, libraries and tools available to
+      the GPGPU programmer, and some applications to condensed matter
+      physics. No physics background required!

+<mediaitem title="Analysis of randomized algorithms via the probabilistic method">
+  <abstract>
+    <p>
+      In this talk, we will give a few examples that illustrate the basic method and show  how it can be used to prove the existence of objects with desirable combinatorial  properties as well as produce them in expected polynomial time via randomized  algorithms.  Our main goal will be to present a very slick proof from 1995 due to  Spencer on the performance of a randomized greedy algorithm for a set-packing  problem.  Spencer, for seemingly no reason, introduces a time variable into his  greedy algorithm and treats set-packing as a Poisson process.  Then, like magic,  he is able to show that his greedy algorithm is very likely to produce a good  result using basic properties of expected value.
+    </p>
+    <p>
+      The probabilistic method is an extremely powerful tool in combinatorics that can be
+      used to prove many surprising results.  The idea is the following: to prove that an
+      object with a certain property exists, we define a distribution of possible objects
+      and use show that, among objects in the distribution, the property holds with
+      non-zero probability.  The key is that by using the tools and techniques of
+      probability theory, we can vastly simplify proofs that would otherwise require very
+      complicated combinatorial arguments.
+    </p>
+    <p>
+      As a technique, the probabilistic method developed rapidly during the latter half of
+      the 20th century due to the efforts of mathematicians like Paul Erdős and increasing
+      interest in the role of randomness in theoretical computer science.  In essence, the
+      probabilistic method allows us to determine how good a randomized algorithm's output
+      is likely to be.  Possibly applications range from graph property testing to
+      computational geometry, circuit complexity theory, game theory, and even statistical
+      physics.
+    </p>
+    <p>
+      In this talk, we will give a few examples that illustrate the basic method and show
+      how it can be used to prove the existence of objects with desirable combinatorial
+      properties as well as produce them in expected polynomial time via randomized
+      algorithms.  Our main goal will be to present a very slick proof from 1995 due to

+      result using basic properties of expected value.
+    </p>
+    <p>
+      Properties of Poisson and Binomial distributions will be applied, but I'll remind
+      everyone of the needed background for the benefit of those who might be a bit rusty.
+      Stat 230 will be more than enough. Big O notation will be used, but not excessively.

+    <p>
+      Theoretical neuroscience is a new discipline focused on constructing mathematical models of brain function.  It has made significant headway in understanding aspects of the neural code.  However, past work has largely focused on small numbers of neurons, and so the underlying representations are often simple.

+    <p>
+      In this talk, I will go over the concepts used in video encoding (such as motion estimation/compensation, inter- and intra- frame prediction, quantization and entropy encoding), and then demonstrate these concepts and algorithms in use in the MPEG-2 and the H.264 video codecs. In addition, some clever optimization tricks using SIMD/vectorization will be covered, assuming sufficient time to cover these topics.

+      With the recent introduction of digital TV and the widespread success
+      of video sharing websites such as youtube, it is clear that the task

+<mediaitem title="The Art of the Propagator">
+  <abstract>
+    <p>
+      We develop a programming model built on the idea that the basic computational elements are autonomous machines interconnected by shared cells through which they communicate. Each machine continuously examines the cells it is interested in, and adds information to some based on deductions it can make from information from the others. This model makes it easy to smoothly combine expression-oriented and constraint-based programming; it also easily accommodates implicit incremental distributed search in ordinary programs.
+
+      This work builds on the original research of Guy Lewis Steele Jr. and was developed more recently with the help of Chris Hanson.

+<mediaitem title="Why Programming is a Good Medium for Expressing Poorly Understood and Sloppily Formulated Ideas">
+  <abstract>
+    <p>
+      I have stolen my title from the title of a paper given by Marvin Minsky in the 1960s, because it most effectively expresses what I will try to convey in this talk.
+    </p>
+
+    <p>
+      We have been programming universal computers for about 50 years. Programming provides us with new tools to express ourselves. We now have intellectual tools to describe "how to" as well as "what is". This is a profound transformation: it is a revolution in the way we think and in the way we express what we think.
+    </p>
+
+    <p>
+      For example, one often hears a student or teacher complain that the student knows the "theory" of some subject but cannot effectively solve problems. We should not be surprised: the student has no formal way to learn technique. We expect the student to learn to solve problems by an inefficient process: the student watches the teacher solve a few problems, hoping to abstract the general procedures from the teacher's behavior on particular examples. The student is never given any instructions on how to abstract from examples, nor is the student given any language for expressing what has been learned. It is hard to learn what one cannot express. But now we can express it!
+    </p>
+
+    <p>
+      Expressing methodology in a computer language forces it to be unambiguous and computationally effective. The task of formulating a method as a computer-executable program and debugging that program is a powerful exercise in the learning process. The programmer expresses his/her poorly understood or sloppily formulated idea in a precise way, so that it becomes clear what is poorly understood or sloppily formulated. Also, once formalized procedurally, a mathematical idea becomes a tool that can be used directly to compute results.
+    </p>
+
+    <p>
+      I will defend this viewpoint with examples and demonstrations from electrical engineering and from classical mechanics.
