6 <short>A talk by Richard Mann; School of Computer Science</short>
9 When an observer moves through a 3D scene, nearby surfaces move faster in the
10 image than do distant surfaces. This effect, called motion parallax, provides
11 an observer with information both about their own motion relative the scene,
12 and about the spatial layout and depth of surfaces in the scene.
15 Classical methods for measuring image motion by computer have concentrated on
16 the cases of optical flow in which the motion field is continuous, or layered
17 motion in which the motion field is piecewise continuous. Here we introduce a
18 third natural category which we call ``optical snow''. Optical snow arises in
19 many natural situations such as camera motion in a highly cluttered 3-D scene,
20 or a passive observer watching a snowfall. Optical snow yields dense motion
21 parallax with depth discontinuities occurring near all image points. As such,
22 constraints on smoothness or even smoothness in layers do not apply.
25 We present a Fourier analysis of optical snow. In particular we show that,
26 while such scenes appear complex in the time domain, there is a simple
27 structure in the frequency domain, and this may be used to determine the
28 direction of motion and the range of depths of objects in the scenes. Finally
29 we show how Fourier analysis of two or more image regions may be combined to
30 estimate heading direction.

111 <short>A talk by Simon Law</short>
114 LaTeX is a document processing system. What this means is you describe
115 the structure of your document, and LaTeX typesets it appealingly.
116 However, LaTeX was developed in the late-80s and is now showing its age.
120 How does it compete against modern systems? By being easily extensible,
121 of course. This talk will describe the fundamentals of typesetting in
122 LaTeX, and will then show you how to extend it with freely available
123 packages. You will learn how to teach yourself LaTeX and how to find
124 extensions that do what you want.
128 As well, there will be a short introduction on creating your own
129 packages, for your own personal use.

143 you might be fixing a bug in someone else's part, and need to merge in
144 the change. What a mess!
148 This talk will explain some Best Practices for developing code in a
149 distributed fashion. Whether you're working side-by-side in the lab, or
150 developing from home, these methods can apply to your team. You will

179 If you have used Unix for a while, you know that you've created
180 configuration files, or dotfiles. Each program seems to want its own
181 particular settings, and you want to customize your environment. In a
182 power-user's directory, you could have hundreds of these files.
186 Isn't it annoying to migrate your configuration if you login to another
187 machine? What if you build a new computer? Or perhaps you made a
188 mistake to one of your configuration files, and want to undo it?
192 In this talk, I will show you how to manage your home directory using
193 CVS, the Concurrent Versions System. You can manage your files, revert
194 to old versions in the past, and even send them over the network to
195 another machine. I'll also discuss how to keep your configuration files

209 represent the network of your friends.
213 Originally, webs-of-trust were directed acyclic graphs of people who had
214 identified each other. This way, if there was a path between you and
215 the person who want to identify, then you could assume that each person
216 along that path had verified the next person's identity.

709 <short>A talk by Jim Elliott. Jim is responsible for IBM's in Open Source
710 activities and IBM's mainframe operating systems for Canada and the
714 Linux and Open Source have become a significant reality in the
715 working world of Information Technology. An indirect result has been a
716 "rebirth" of the mainframe as a strategic platform for enterprise
717 computing. In this session Jim Elliott, IBM's Linux Advocate, will provide
718 an overview of these technologies and an inside look at IBM's participation
719 in the community. Jim will examine Linux usage on the desktop, embedded
720 systems and servers, a reality check on the common misconceptions that
721 surround Linux and Open Source, and an overview of the history and current
722 design of IBM's mainframe servers.</p>
724 Jim Elliott is the Linux Advocate for IBM Canada. He is responsible
725 for IBM's participation in Linux and Open Source activities and IBM's
726 mainframe operating systems in Canada and the Caribbean. Jim is a popular
727 speaker on Linux and Open Source at conferences and user groups across the
728 Americas and Europe and has spoken to over 300 organizations over the past
729 three years. Over his 30 years with IBM he has been the co-author of over
730 15 IBM publications and he also coordinated the launch of Linux on IBM
731 mainframes in the Americas. In his spare time, Jim is addicted to reading
732 historical mystery novels and travel to their locales.

750 <short>Metaprogramming your way to stunning effects.</short>
753 Modern graphics processors allow developers to upload small "shader
754 programs" to the GPU, which can be executed per-vertex or even
755 per-pixel during the rendering. Such shaders allow stunning effects to
756 be performed in real-time, but unfortunately aren't very easy to
757 program since one generally has to write them at the assembly level.
759 Recently a few high-level languages for shader programming have become
760 available. Sh, a result of research at UW, is one such language. It
761 allows programming powerful shaders in simple and intuitive ways. Sh
762 is particularily interesting because of the way it is
763 implemented. Instead of coming up with a language grammar and writing
764 a full-fledged compiler, Sh is implemented as a C++ library, and
765 shader programs are effectively written in C++. The actual compilation
766 then takes place in a manner similar to JIT (Just-in-time)
767 compilers. This has many advantages over the traditional approach,
768 including C++'s familiar syntax for users, and much less work for the
771 In this talk I will give an overview of GPUs and the Sh language as
772 well as some interesting details on how Sh was implemented.
773 </p><p> <!-- Is there a bio tag -->
774 Stefanus Du Toit is a research assistant at the University of
775 Waterloo. He has implemented the current version of Sh from scratch
776 and is actively developing it under supervision of Michael McCool, the
777 original designer of the language.

782 title="vi: the visual editor">
783 <short>It's not 6.</short>
786 <p>In 1976, a University of California Berkeley student by the name of
787 Bill Joy got sick of his text editor, ex. So he hacked it such that
788 he could read his document as he wrote it. The result was "vi", which
789 stands for VIsual editor. Today, it is shipped with every modern
790 Unix system, due to its global influence.</p>
792 <p>In this talk, you will learn how to use vi to edit documents
793 quickly and efficiently. At the end, you should be able to:</p>
796 <li>Navigate and search through documents</li>
797 <li>Cut, copy, and paste across documents</li>

1334 January 2) until 4:30 PM of the day before elections (Sunday, January 12).
1335 In order to nominate someone you can either e-mail me directly, by depositing
1336 a form with the required information in the CSC mailbox in the Mathsoc office
1337 or by writing the nomination and clearly marking it as such on the large

1339 Please include the name of the person to be nominated as well as the position
1340 you wish to nominate them for.</p>
1342 <p>Candidates must be full members of the club. This means they must have paid
1343 their membership for the given term and (due to recent changes in the
1344 constitution) must be full-time undergraduate math students.
1345 The same requirements hold for those voting. Please bring your Watcard to
1346 the elections so that I can verify this. I will have a list of members with
1349 <p>The positions open are:</p>
1351 <p><b>President</b> -- appoints all commitees of the club, calls and presides at all
1352 meetings of the club and audits the club's financial records. Really, this
1353 is the person in charge.</p>
1355 <p><b>Vice President</b> -- assumes President's duties in case he/she is absent,
1356 plans and coordinates events with the programmes committee and assumes any
1357 other duties delegated by the President.
1358 This is a really fun job if you enjoy coordinating events!</p>
1360 <p><b>Secretary</b> -- keeps minutes of the meetings and cares for any correspondence.
1361 A fairly light job, good choice if you just want to see what being an exec
1364 <p><b>Treasurer</b> -- maintains all the finances of the club.
1365 If you like money and keeping records, this is the job for you!</p>
1367 <p>Additionally a Systems Administrator will be picked by the new executive.</p>
1369 <p>Last term was a great term for the CSC -- many events, some office renovations
1370 and a much improved image were all part of it. I hope to see the next term's
1371 exec continue this. If you're interested in seeing this happen, do consider

1388 <p>Stephen Kleene developed regular expressions to describe what he
1389 called <q>the algebra of regular sets.</q> Since he was a pioneering

1393 <p>Regular expressions can be powerful tools to manipulate text.
1394 You will be introduced to them in this talk. As well, we will go
1395 further than the rigid mathematical definition of regular
1396 expressions, and delve into POSIX regular expressions which are
1397 typically available in most Unix tools.</p>

1426 <p>Unix was one of the first electronic typesetting platforms. The

1429 Later, Donald Knuth invented a typesetting system called

1434 <p>L<sup><small>A</small></sup>T<small>E</small>X is a macro package

1632 <p>Templates are a useful feature in C++ when it comes to writing
1633 type-independent data structures and algorithms. But that's not all
1634 they can be used for. Essentially, it is possible to write certain
1635 programs in C++ that execute completely at compile-time rather
1636 than run-time. Combined with some optimisations this is an interesting
1637 twist on regular C++ programming.</p>
1639 <p>This talk will give a short overview of the features of templates
1640 and then go on to describe how to "abuse" templates to perform complex
1641 computations at compile time. The speaker will present three programs of
1642 increasing complexity which execute at compile time. First a factorial
1643 listing program, then a prime listing program will be presented. Finally
1644 the talk will conclude with the presentation of a <i>Mandelbrot

1750 What is the next step in the evolution of computer languages?
1751 Intelligent agents? Distributed objects? or visual languages?
1754 Visual languages overcome many of the drawbacks and limitations
1755 of the textual languages that software development is based on
1756 today. Do you think about programming in a linear fashion? Or do
1757 you draw a mental picture of your algorithm and then linearize it
1758 for the benefit of your compiler? Wouldn't it be nice if you could
1759 code the same way you think?
1762 Visual C++ and Visual BASIC aren't visual languages, but Prograph
1763 is. Prograph is a commercially available, visual, object-oriented,
1764 data-flow language. It is well suited to graphical user interface
1765 development, but is as powerful for general-purpose programming as
1766 any textual language.
1769 The talk will comprise a discussion of the problems of textual
1770 languages that visual languages solve, a live demonstration of
1771 Prograph, and some of my observations of the applications of
1772 Prograph to software development.

2124 <p>The Internet and the Web have revolutionized our communications, our access
2125 to information and our business methods. However, there is still much room
2126 for improvement. Frank Clegg will discuss Microsoft's vision for what is
2127 beyond browsing and the dotcom. Microsoft .NET (pronounced "dot-net") is a
2128 new platform, user experience and set of advanced software services planned
2129 to make all devices work together and connect seamlessly. With this next
2130 generation of software, Microsoft's goal is to make Internet-based
2131 computing and communications easier to use, more personalized, and more
2132 productive for businesses and consumers. In his new position of president
2133 of Microsoft Canada Co., Frank Clegg will be responsible for leading the
2134 organization toward the delivery of Microsoft .NET. He will speak about
2135 this new platform and the next generation Internet, how software developers
2136 and businesses will be able to take advantage of it, and what the .NET
2137 experience will look like for consumers and business users.</p>
2139 <h3>The Speaker</h3>
2140 <p>Frank Clegg was appointed president of Microsoft Canada Co. this month.
2141 Prior to his new position, Mr. Clegg was vice-president, Central Region,
2142 Microsoft Corp. from 1996 to 2000. In this capacity, he was responsible for
2143 sales, support and marketing activities in 15 U.S. states. Mr. Clegg joined
2144 Microsoft Corp. in 1991 and headed the Canadian subsidiary until 1996.
2145 During that time, Mr. Clegg was instrumental in introducing several key
2146 initiatives to improve company efficiency, growth and market share. Mr.
2147 Clegg graduated from the University of Waterloo in 1977 with a B. Math.</p>

2194 <p>For doing linux burns. It was allocated money on the budget

2196 burner with that (8x rewrite).</p>
2197 <p>The obvious things to sell are Linux Distros and BSD variants.
2198 Are there any other software that we can legally burn and sell
2203 <p>Just a talk of the topics to be covered, when, where, whatnot.
2204 Mike was right on this one, this should have been done earlier

2208 <dt>Game Contest</dt>
2210 <p>We already put a bit of work into planning the Othello contest
2211 before I read Mike's post. I still think it's viable. I've got
2212 at least 2 people interested in writing entries for it. This

2346 <short>Bored of GNU/Linux? Try this experimental operating
2349 <p>GNU Hurd is an operating system kernel based on the microkernel
2350 architecture design. It was the original GNU kernel, predating Linux,
2351 and is still being actively developed by many volunteers.</p>
2352 <p>The Toronto-area Hurd Users Group, in co-operation with the Computer
2353 Science Club, is hosting an afternoon to show the Hurd to anyone
2354 interested. Jeff Bailey, a Hurd developer, will give a presentation on
2355 the Hurd, followed by a GnuPG/PGP keysigning party. To finish it off,
2356 James Morrison, also a Hurd developer, will be hosting a Debian
2357 GNU/Hurd installation session.</p>
2358 <p>All interested are invited to attend. Bring your GnuPG/PGP fingerprint
2359 and mail your key to sjdutoit@uwaterloo.ca with the subject
2360 ``keysigning'' (see separate announcement).</p>

2367 title="GnuPG/PGP Keysigning Party">
2368 <short>Get more signatures on your key!</short>
2371 GnuPG and PGP provide public-key based encryption for e-mail and
2372 other electronic communication. In addition to preventing others
2373 from reading your private e-mail, this allows you to verify that an
2374 e-mail or file was indeed written by its perceived author.
2377 In order to make sure a GnuPG/PGP key belongs to the respective
2378 person, the key must be signed by someone who has checked the
2379 user's key fingerprint and verified the user's identification.
2382 A keysigning party is an ideal occasion to have your key signed by
2383 many people, thus strengthening the authority of your key. Everyone
2384 showing up exchanges key signatures after verifying ID and
2385 fingerprints. The Computer Science Club will be hosting such a
2386 keysigning party together with the Hurd presentation by THUG (see
2387 separate announcement). See
2388 <a href="http://www.student.math.uwaterloo.ca/~sjdutoit/"> the
2389 keysigning party homepage</a> for more information.
2392 Before attending it is important that you mail your key to
2393 sjdutoit@uwaterloo.ca with the subject ``keysigning.'' Also make
2394 sure to bring photo ID and a copy of your GnuPG/PGP fingerprint on
2395 a sheet of paper to the event.

2638 <short>Abusing template metaprogramming in C++; aka. writing a

2641 <p>Templates are a useful feature in C++ when it comes to writing
2642 type-independent data structures and algorithms. Relatively soon
2643 after their appearance it was realised that they could be used to
2644 do much more than this. Essentially it is possible to write
2645 certain programs in C++ that execute <i>completely at compile
2646 time</i> rather than run time. Combined with constant-expression
2647 optimisation this is an interesting twist on regular C++
2649 <p>This talk will give a short overview of the features of
2650 templates and then go on to describe how to "abuse"
2651 templates to perform complex computations at compile time. The
2652 speaker will present three programs of increasing complexity which
2653 execute at compile time. First a factorial listing program, then a
2654 prime listing program will be presented. Finally the talk will
2655 conclude with the presentation of a <b>Mandelbrot generator running
2656 at compile time</b>.</p>
2658 <p>If you are interested in programming for the fun of it, the C++
2659 language or silly tricks to do with languages, this talk is for
2660 you. No C++ knowledge should be necessary to enjoy this talk, but
2661 programming experience will make it more worthwile for you.</p>

2686 <h3>Frequently Asked Questions</h3>
2688 <p><b>Q: </b>What is GNU/Linux?<br />
2689 <b>A: </b>GNU/Linux is a free operating system for your computer. It is mostly
2690 written by talented volunteers who like to share their efforts.
2693 <p><b>Q: </b>Free?<br />
2694 <b>A: </b>GNU/Linux is available for zero-cost. As well, it allows you such
2695 freedom to share it with your friends, or to modify the software to
2696 your own needs and share that with your friends. It's very friendly.
2699 <p><b>Q: </b>What is an InstallFest?<br />
2700 <b>A: </b>An InstallFest is a meeting where volunteers help people install
2701 GNU/Linux on their computers. It's also a place to meet users, and
2702 talk to them about running GNU/Linux.
2705 <p><b>Q: </b>What kind of computer do I need to use GNU/Linux?<br />
2706 <b>A: </b>Almost any recent computer will do. If you have an old machine
2707 kicking around, you can install GNU/Linux on it as well. If it is
2708 at least 5 years old, it should be good enough.
2711 <p><b>Q: </b>Can I have Windows and GNU/Linux on the same computer?<br />
2712 <b>A: </b>If you can run Windows now, and you have an extra gigabyte (GB) of
2713 disk space to spare; then it should be possible.
2716 <p><b>Q: </b>What should I bring if I want to install GNU/Linux?<br />
2717 <b>A: </b>You will want to bring:</p>
2720 <li>Monitor and monitor cable</li>

2748 Unfortunately, software developers do not read licenses thoroughly, nor
2749 well. In this talk, we will read the entire GNU GPL and explain the
2750 implications of its passages. Along the way, we will debunk some myths
2751 and clarify common misunderstandings.
2754 After this session, you ought to understand what the GNU GPL means, how
2755 to use it, and when you cannot use it. This session should also give
2756 you some insight into the social implications of this work.

2762 title="Metaprogramming GPUs">
2763 <short>A talk by Michael McCool of the Computer Graphics Lab.</short>
2766 Modern graphics accelerators, or "GPUs", have embedded high-performance
2767 programmable components in the form of vertex and fragment shading units.
2768 Recently, these units have evolved from 8-bit computations to floating-point,
2769 and other operations provide array gather, scatter, and summation.
2770 These capabilities make GPUs akin to array processors of the
2771 past, but with a difference: every PC now has one! I am interested
2772 in finding the best way to exploit this computational capacity for not
2773 only graphics but for general-purpose computation.
2775 Current APIs permit specification of the programs for GPUs
2776 using an assembly-language level interface. Compilers for high-level
2777 shading languages are available, such as NVIDIA's Cg, and OpenGL 2.0 and
2778 DirectX will also include standardized shading languages. This talk will
2779 review these. However, compilers for these languages read in an external
2780 string specification, which can be inconvenient.
2782 However, it is possible, using standard C++, to define a high-level
2783 shading language directly in the API. Such a language can be nearly
2784 indistinguishable from a special-purpose programming language, yet
2785 permits more direct interaction with the specification of textures
2786 (arrays) and parameters, simplifies implementation, and enables
2787 on-the-fly generation, manipulation, and specialization of shader programs.
2788 A shading language built into the API also permits the lifting of
2789 C++ host language type, modularity, and scoping constructs into the shading
2790 language without any additional implementation effort. Such an
2791 embedded language could be used to program other embedded processors
2792 (such as DSP chips in sound cards) or even to generate machine language
2793 on the fly for the host CPU.

2834 Whenever a language is designed by a committee, it is common
2835 wisdom to avoid it. Not so with Perl, for it cannot get
2836 worse. However strange these Perl people seem, Perl 6 is a
2837 good thing coming. In this talk, I will demonstrate some Perl
2838 5 programs, and talk about their Perl 6 counterparts, to show
2839 you that Perl 6 will be cleaner, friendlier, and prettier.

2848 Samba is a free implementation of the Server Message Block (SMB)
2849 protocol. It also implements the Common Internet File System (CIFS)
2850 protocol, used by Microsoft Windows 95/98/ME/2000/XP to share files and
2852 SMB was originally developed in the early to mid-80's by IBM and was
2853 further improved by Microsoft, Intel, SCO, Network Appliances, Digital
2854 and many others over a period of 15 years. It has now morphed into CIFS,
2855 a form strongly influenced by Microsoft. </p><p>
2856 Samba is considered to be one of the key projects for the acceptance of
2857 GNU/Linux and other Free operating systems (e.g. FreeBSD) in the
2858 corporate world: a traditional Windows NT/2000 stronghold. </p><p>

2897 <short>Marcus Brinkmann, a GNU Hurd developer, talks about the Hurd server interfaces, at the heart of a GNU/Hurd system</short>
2899 <p>The Hurd server interfaces are at the heart of the Hurd system. They
2900 define the remote procedure calls (RPCs) that are used by the servers, the
2901 GNU C library and the utility programs to communicate with the Hurd system
2902 and to implement the POSIX personality of the Hurd as well as other
2905 <p>This talk is a walk through the Hurd RPCs, and will give an overview of how
2906 they are used to implement the system. Individual RPCs will be used to
2907 illustrate important or exciting features of the Hurd system in general,
2908 and it will be shown how those features are accessible to the user at the
2909 command line, too.</p>
2913 <p>Marcus Brinkmann is a math student at the Ruhr-Universitaet Bochum in
2914 Germany. He is one of maintainers of the GNU Hurd project and the
2915 initiator of the Debian GNU/Hurd binary distribution. He designed and
2916 implemented the console subsystem of the Hurd, wrote the FAT filesystem
2917 server, and fixed a lot of bugs, thus increasing the stability and
2918 usability of the system.</p>

2924 title="A GNU Approach to Virtual Memory Management in a Multiserver Operating System">
2925 <short>Neal Walfield, a GNU Hurd developer, talks about a possible Virtual Memory Management subsystem for the GNU Hurd</short>
2927 <p>Virtual memory management is one of the cornerstones of multiuser
2928 operating systems. Most systems available today place all of the
2929 policy in a monolithic virtual memory manager, VMM, isolated from the
2930 rest of the system. Although secure and lightweight, users have no
2931 way to communicate their anticipated memory needs and usage to the
2932 system pager. As a result, the VMM can only implement a global paging
2933 policy (typically, an approximation of LRU) which may be good on
2934 average but is best for nobody.</p>
2936 <p>With the port of Hurd to the L4 microkernel, this situation is being
2937 readdressed. Due to its more distributed nature, a centralized
2938 resource manager is not only more difficult to implement efficiently
2939 but also contrary to the philosophy of the rest of the system. We are
2940 currently exploring a model whereby each program is fully self-paged
2941 and all compete for memory from a physical memory server. This talk
2942 will first discuss how paging currently works in Mach and other
2943 systems. An argument for an external paging policy will then be
2944 presented followed by the requirements of such a design and the design
