<mediaitem title="Functional Lexing and Parsing">
This talk will describe a non-traditional functional approach to the
classical problems of lexing (breaking a stream of characters into
"words" or tokens) and parsing (identifying tree structure in a stream
of tokens based on a grammar, e.g. for a programming language that
needs to be compiled or interpreted). The functional approach can
clarify and organize a number of algorithms that tend to be opaque in
their conventional imperative presentation. No prior background in
functional programming, lexing, or parsing is assumed.

<mediaitem title="Rapid Prototyping and Mathematical Art">
The combination of computer graphics, geometry, and rapid
prototyping technology has created a wide range of exciting
opportunities for using the computer as a medium for creative
expression. In this talk, I will describe the most popular
technologies for computer-aided manufacturing, discuss
applications of these devices in art and design, and survey
the work of contemporary artists working in the area (with a
focus on mathematical art). The talk will be primarily
non-technical, but I will mention some of the mathematical
and computational techniques that come into play.</p>

<mediaitem title="Off-the-Record Messaging: Useful Security and Privacy for IM">
Instant messaging (IM) is an increasingly popular mode of communication
on the Internet. Although it is used for personal and private
conversations, it is not at all a private medium. Not only are all of
the messages unencrypted and unauthenticated, but they are all
routedthrough a central server, forming a convenient interception point
for an attacker. Users would benefit from being able to have truly
private conversations over IM, combining the features of encryption,
authentication, deniability, and forward secrecy, while working within
their existing IM infrastructure.
In this talk, I will discuss "Off-the-Record Messaging" (OTR), a widely
used software tool for secure and private instant messaging. I will
outline the properties of Useful Security and Privacy Technologies that
motivated OTR's design, compare it to other IM security mechanisms, and
talk about its ongoing development directions.

Ian Goldberg is an Assistant Professor of Computer Science at the
University of Waterloo, where he is a founding member of the
Cryptography, Security, and Privacy (CrySP) research group. He holds a
Ph.D. from the University of California, Berkeley, where he discovered
serious weaknesses in a number of widely deployed security systems,
including those used by cellular phones and wireless networks. He also
studied systems for protecting the personal privacy of Internet users,
which led to his role as Chief Scientist at Zero-Knowledge Systems (now
known as Radialpoint), where he commercialized his research as the
Freedom Network.
<mediaitem title="Privacy by Design">
Globally, issues about information privacy in the marketplace have emerged in tandem with the dramatic and escalating increase in information stored
in electronic formats. Data mining, for example, can be extremely valuable for businesses, but in the absence of adequate safeguards, it can
jeopradize informational privacy. Dr. Ann Cavoukian talks about how to use technology to enhance privacy. Some of the technologies discussed
included instant messaging, RFID tags and Elliptical Curve Cryptography (ECC). Then Dr. Cavoukian explained the “7 Privacy – Embedded Laws” followed
by a discussion on a biometrics solution to encryption.

Dr. Ann Cavoukian, as the Information and Privacy Commissioner, oversees the operations of Ontario's freedom of information and protection of
privacy laws, which apply to both provincial and municipal government organizations. She serves as an officer of the legislature, independent of the
government of the day. Ann joined the Information and Privacy Commission in 1987 as its first Director of Compliance and was appointed Assistant
Commissioner in 1990, responsible for the protection of privacy and compliance with the Freedom of Information and Protection of Privacy Acts. Prior
to her work at the Commission, Ann headed the Research Services Branch of the Ministry of the Attorney General. Ann received her M.A. and Ph.D. in
Psychology from the University of Toronto, where she specialized in criminology and lectured on psychology and the criminal justice system. Ann
speaks extensively on the importance of privacy around the world. Her published works include a recent book on privacy called "Who Knows:
Safeguarding Your Privacy in a Networked World."
<mediaitem title="C++0x - An Overview">
A good programming language is far more than a simple collection of
features. My ideal is to provide a set of facilities that smoothly work
together to support design and programming styles of a generality beyond
my imagination. Here, I briefly outline rules of thumb (guidelines,
principles) that are being applied in the design of C++0x. Then, I
present the state of the standards process (we are aiming for C++09) and
give examples of a few of the proposals such as concepts, generalized
initialization, being considered in the ISO C++ standards committee.
Since there are far more proposals than could be presented in an hour,
I'll take questions.

<mediaitem title="Copyright vs Community in the Age of Computer Networks">
Copyright developed in the age of the printing press, and was designed
to fit with the system of centralized copying imposed by the printing
press. But the copyright system does not fit well with computer networks,
and only draconian punishments can enforce it.
The global corporations that profit from copyright are lobbying for
draconian punishments, and to increase their copyright powers, while
suppressing public access to technology. But if we seriously hope to serve
the only legitimate purpose of copyright -- to promote progress, for the
benefit of the public -- then we must make changes in the other

<mediaitem title="The Free Software Movement and GNULinux Operating System, a talk by Richard Stallman at UCSD">
Richard Stallman will speak about the goals and philosophy of the Free
Software Movement, and the status and history the GNU Operating System,
which in combination with the kernel Linux is now used by tens of millions
of users world-wide.
Richard Stallman launched the development of the GNU operating system in
1984. GNU is free software: everyone has the freedom to copy it and
redistribute it, as well as to make changes either large or small. The
GNU/Linux system, basically the GNU operating system with Linux added, is
used on tens of millions of computers today.
"The reason I care especially, is that there is a philosophy associated
with the GNU project, and this philosophy is actually the reason why there
is a system -- and that is that free software is not just convenient and
not just reliable.... More important than convenience and reliability is
freedom -- the freedom to cooperate. What I'm concerned about is not
individual people or companies so much as the kind of way of life that we
have. That's why I think it's a distraction to think about fighting

<mediaitem title="Riding The Multi-core Revolution">
For decades, mainstream parallel processing has been thought of as
inevitable. Up until recent years, however, improvements in manufacturing
processes and increases in clock speed have provided software with free
Moore's Law-scale performance improvements on traditional single-core
CPUs. As per-core CPU speed increases have slowed to a halt, processor
vendors are embracing parallelism by multiplying the number of cores on
CPUs, following what Graphics Processing Unit (GPU) vendors have been
doing for years. The Multi-core revolution promises to provide
unparallelled increases in performance, but it comes with a catch:
traditional serial programming methods are not at all suited to
programming these processors and methods such as multi-threading are
cumbersome and rarely scale beyond a few cores. Learn how, with hundreds
of cores in desktop computers on the horizon, a local software company is
looking to revolutionize the way software is written to deliver on the
promise multi-core holds.

<mediaitem title="ReactOS - An Open Source OS Platform for Learning">
The ReactOS operating system has been in development for over eight years
and aims to provide users with a fully functional and Windows-compatible
distribution under the GPL license. ReactOS comes with its own Windows
2003-based kernel and system utilities and applications, resulting in an
environment identical to Windows, both visually and internally.
More than just an alternative to Windows, ReactOS is a powerful platform
for academia, allowing students to learn a variety of skills useful to
software testing, development and management, as well as providing a rich
and clean implementation of Windows NT, with a kernel compatible to
published internals book on the subject.
This talk will introduce the ReactOS project, as well as the various
software engineering challenges behind it. The building platform and
development philosophies and utilities will be shown, and attendees will
grasp the vast amount of effort and organization that needs to go into
building an operating system or any other similarly large project. The
speaker will gladly answer questions related to his background, experience
and interests and information on joining the project, as well as any other
related information.
Slides from the talk are available
<a href="">here</a>.
Alex Ionescu is currently studying in Software Engineering at Concordia
University in Montreal, Quebec and is a Microsoft Technical Student
Ambassador. He is the lead kernel developer of the ReactOS Project and
project leader of TinyKRNL. He regularly speaks at Linux and Open Source
conferences around the world and will be a lecturer at the 8th
International Free Software Forum in Brazil this April, as well as
providing hands-on workshops and lectures on Windows NT internals and

You might think that your spam filter works well and couldn't be
improved. Are you sure? You may think that the risk of losing
important mail outweighs the benefit of using a filter. Could you
convince someone who holds the other opinion? If I told you that my

what I meant? Would you be able to translate that 99-percent into
the risk of losing an important message?

modules which might be no more than a few pixels in size. We had to do
that in order to establish Semacode, a local start up company that makes a
software barcode reader for cell phones. The applications vary from
ubiquitous computing to advertising. Simon Woodside (founder) will discuss
what it's like to start a business and how the imaging code works.

Eric LaForest delivers a crash-course on modern stack computing, the Forth
programming language, and some projects of his own. Stack systems have
faster procedure calls and reduced complexity (shorter pipeline, simpler
compilation) relative to their conventional counterparts, as well as more
consistent performance, which is very important for real-time systems.
Many consider stack-based architecture's crowning feature, however, to be
the unrivalled price-to-performance ratio.

<mediaitem title="Rico Mariani: Eighteen Years in the Software Tools Business">
Rico Mariani, (BMath CS/EEE 1988) now an (almost) 18 year Microsoft
veteran but then a CSC president comes to talk to us about the evolution
of software tools for microcomputers. This talk promises to be a little
bit about history and perspective (at least from the Microsoft side
of things) as well as the evolution of software engineers, different types
of programmers and their needs, and what it's like to try to make the
software industry more effective at what it does, and sometimes succeed!
Particularly illuminating are his responses to advocates of
free/open-source software.
