<mediaitem title="How Browsers Work">
<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.

<mediaitem title="General Purpose Computing on Graphics Cards">
<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.

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.

<mediaitem title="How to build a brain: From single neurons to cognition">
<abstract>
<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. In this talk I demonstrate how the ideas underlying these simple forms of representation can underwrite a representational hierarchy that scales to support sophisticated, structure-sensitive representations.

pointer architecture (SPA), which is built on this hierarchy
and allows the manipulation, processing, and learning of structured
representations in neurally realistic models. I demonstrate the
architecture on Progressive Raven's Matrices (RPM), a test of
general fluid intelligence.

<mediaitem title="A Brief Introduction to Video Encoding">
<abstract>
<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.
</p>
<p>
With the recent introduction of digital TV and the widespread success
of video sharing websites such as youtube, it is clear that the task
of lossily compressing video with good quality has become important.
Similarly, the complex algorithms involved require high amounts of
optimization in order to run fast, another important requirement for
any video codec that aims to be widely used/adopted.

Hi! I'm Jeff Potter, author of Cooking for Geeks (O'Reilly Media, 2010), and I'm doing a "D.I.Y. Book Tour" to talk
about my just-released book. I'll talk about the food science behind what makes things yummy, giving you a quick
primer on how to go into the kitchen and have a fun time turning out a good meal.
Depending upon the space, I’ll also bring along some equipment or food that we can experiment with, and give you a chance to play with stuff and pester me with questions.

<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.

I'll survey the evolution of our computer science curriculum over the
past thirty-five years to try to convey the reasons (not always entirely
rational) behind our current mix of courses and their division into core

some candid comments about the state of CS at UW and how it might be
improved.

<p>
The OpenCL contest will be split into two sections of participants: Open Submission and Problem Set.
</p>
<ul>
<li>
If you choose to participate in the Open Submission section, you will be able to submit any project which runs in the OpenCL environment. Your submission will be judged subjectively by a panel of three judges.
</li>
<br />
<li>
On the other hand, if you participate in the Problem Set section, you will be required to implement several programs to solve a set of problems (released on the 24th). Your submissions will be judged objectively by an electronic judge. In this section, you will be scored on correctness and efficiency.
</li>
<br />
<li>
You may choose to work in a team of up to three people, or alone.
</li>
</ul>
<p>
In order to process your registration, we'll need your Quest ID, an email address, and your choice of team/section participation. Please fill out the form below:
</p>
<p>
<form action="register.cgi" method="post">

<section title="UNIX 102 Reference Material">
<p>
This page contains some <a href="http://programmerryangosling.tumblr.com/">links</a> to material covered during UNIX 101 and 102,
as well as some extracurricular content for you to review in your free
time.
</p>
<p>
The text file for the great editor race is available <a href="queue.txt">here</a>.
</p>
<p>
To begin with the first exercise, you will need the following file.
To download it and untar it, execute the following commands:
<pre>
wget http://csclub.uwaterloo.ca/unix102/vim_exercise.tar
tar -xvf vim_exercise.tar
</pre>
</p>
<p>
You can also download the <a href="unix101.pdf">slides</a> or <a href="cheatsheet.pdf">cheatsheet</a> handout from UNIX 101.
</p>
</section>
<section title="vim References">
<p>
First and foremost, make sure you have tried running vimtutor. This
program is available on the CSC systems, as well as the student.cs and
student.math environments. Try the following commands from a shell:
<pre>
ssh userid@linux.student.cs.uwaterloo.ca
vimtutor
</pre>
This <a href="http://newbiedoc.sourceforge.net/text_editing/vim.html#BUILT-IN-HELP-VIM">document</a> from sourceforge should also prove to be useful.
</p>
</section>
<section title="bash References">
<p>
From the GNU bash reference manual (a very good source of information,
albeit a little arcane and verbose):
</p>
<ul>
<li><a href="http://www.gnu.org/software/bash/manual/bash.html#What-is-a-shell_003f">What is a shell?</a></li>
<li><a href="http://www.gnu.org/software/bash/manual/bash.html#Redirections">Redirecting input/output</a></li>
<li><a href="http://www.gnu.org/software/bash/manual/bash.html#Pattern-Matching">Globbing</a></li>
<li><a href="http://www.gnu.org/software/bash/manual/bash.html#Quoting">Quotes/escapes</a></li>
<li><a href="http://www.gnu.org/software/bash/manual/bash.html#Compound-Commands">Conditional and looping constructs</a></li>

</ul>
<p>
Here are some example bash scripts covered in today's lecture:
</p>
<ul>
<li>Simple script whose parameters are any number of text files, that will
print all the files and filenames to standard output: <a href="appender.sh">appender</a></li>
<li>RunC clone, that takes in a filename and executes all the tests it
can find for it in the current directory: <a href="walkc.sh">WalkC</a></li>
<li>Script that scrapes concert website for tickets and sends emails/text
messages when tickets are available: <a href="tickets_email.sh">tickets_email</a></li>
</ul>

<section title="Regular Expression References">
<p>
This
<a href="http://www.regular-expressions.info/quickstart.html">page</a>
is a good brief reference for regular expressions.
</p>
</section>
<section title="git References">
<p>
Look to the <a href="http://gitref.org/index.html">gitref</a> for a git
reference, of course. As well, here's an article I found claiming to list
the <a href="http://sixrevisions.com/resources/git-tutorials-beginners/">top 10 git tutorials</a>.
Whether or not that's true, you should still learn something.
Here is also a brief review of the commands we intended to cover today.
</p>
<p> This clones a copy of the codebase for you to work on locally:
<pre>
git clone
</pre>
This "pulls" (updates with) any new changes others have made since you last
worked on the code, so they are now part of your local code:
<pre>
git pull
</pre>
This adds new files to the git repository:
<pre>
git add [files]
</pre>
This commits any of the changes that you've recently made in [files] (or -a
for everything), getting ready to "push" the changes to other users:
<pre>
git commit [files] (-a)
</pre>
This "pushes" (sends) your changes back to the "master" repository,
allowing other people working on the project to "pull" your changes.
<pre>
git push
</pre>
</p>
</section>
<section title="Beyond UNIX 10X">
<p>
You might be surprised - almost all the information on this page was at
one point found using Google. Remember, your best resources for learning
more about UNIX are your friends, your manpages, and the internet. So
fire up your favorite search engine, and get learning!
