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 and optional. After some remarks about constraints and opportunities in the near future, I'll open the floor to discussion, and hope to hear some candid comments about the state of CS at UW and how it might be improved.
About the speaker:
Prabhakar Ragde is a Professor in the School of Computer Science at UW. He was Associate Chair for Curricula during the period that saw the creation of the Bioinformatics and Software Engineering programs, the creation of the BCS degree, and the strengthening of the BMath/CS degree.

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 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.

Finding shortest paths is a problem that comes up in many applications: Google maps, network routing, motion planning, connectivity in social networks, and etc. The domain may be a graph, either explicitly or implicitly represented, or a geometric space.
Professor Lubiw will survey the field, from Dijkstra's foundational algorithm to current results and open problems. There will be lots of pictures and lots of ideas.

Cairo is an open source, cross platform, vector graphics library with the ability to output to many kinds of surfaces, including PDF, SVG and PNG surfaces, as well as X-Window, Win32 and Quartz 2D backends.
Unlike the raster graphics used with programmes and libraries such as The Gimp and ImageMagick, vector graphics are not defined by grids of pixels, but rather by a collection of drawing operations. These operations detail how to draw lines, fill shapes, and even set text to create the desired image. This has the advantages of being infinitely scalable, smaller in file size, and simpler to express within a computer programme.
This talk will be an introduction to the concepts and metaphors used by vector graphics libraries in general and Cairo in particular.

I transitioned from writing software in imperative, object-oriented (OO) programming languages to doing functional programming (FP) full-time, and you can do it, too! In this talk, I'll make a case for using FP for real-world development, cover some cases where common FP language features substitute for design patterns and OOP structure, and provide some examples of translating traditional OO design patterns into functional code.
Due to battery shenanigans, not the entire talk was recorded. Instead, you can get the slides for this talk at [the talks section of her site](<https://hashman.ca/osb-2016/>).

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.
Dr. Bjarne Stroustrup is the original designer and implementer of the C++ Programming Language.

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 direction.
This talk by Richard M. Stallman is broken into two parts: the main talk and the question and answer sessions following the talk. Both are available in only Ogg/Theora format in keeping with Stallman's wishes. They are available under the [ Creative Commons NoDerivs 1.0](<http://creativecommons.org/licenses/nd/1.0/>) license.

No Matter Who's Winning the War on General Purpose Computing, You're Losing
If cyberwar were a hockey game, it'd be the end of the first period and the score would be tied 500-500. All offense, no defense.
Meanwhile, a horrible convergence has occurred as everyone from car manufacturers to insulin pump makers have adopted the inkjet printer business model, insisting that only their authorized partners can make consumables, software and replacement parts -- with the side-effect of making it a felony to report showstopper, potentially fatal bugs in technology that we live and die by.
And then there's the FBI and the UK's David Cameron, who've joined in with the NSA and GCHQ in insisting that everyone must be vulnerable to Chinese spies and identity thieves and pervert voyeurs so that the spy agencies will always be able to spy on everyone and everything, everywhere.
It's been fifteen years since the copyright wars kicked off, and we're still treating the Internet as a glorified video-on-demand service -- when we're not treating it as a more perfect pornography distribution system, or a jihadi recruitment tool.
It's all of those -- and more. Because it's the nervous system of the 21st century. We've got to stop treating it like a political football.

Deep networks can be learned efficiently from unlabeled data. The layers of representation are learned one at a time using a simple learning module, called a "Restricted Boltzmann Machine" that has only one layer of latent variables. The values of the latent variables of one module form the data for training the next module. Although deep networks have been quite successful for tasks such as object recognition, information retrieval, and modeling motion capture data, the simple learning modules do not have multiplicative interactions which are very useful for some types of data.
The talk will show how a third-order energy function can be factorized to yield a simple learning module that retains advantageous properties of a Restricted Boltzmann Machine such as very simple exact inference and a very simple learning rule based on pair-wise statistics. The new module contains multiplicative interactions that are useful for a variety of unsupervised learning tasks. Researchers at the University of Toronto have been using this type of module to extract oriented energy from image patches and dense flow fields from image sequences. The new module can also be used to allow motions of a particular style to be achieved by blending autoregressive models of motion capture data.

Alex Tsay from AeroFS will talk about the high availability distributed file systems they develop. The CAP Theorem outlined the fundamental limitations of a distributed system. When designing a distributed system, one has to constantly be aware of the trade-off between consistency and availability. Most distributed systems are designed with consistency in mind. However, AeroFS has decided to build a high-availability file system instead. In this tech talk, I'll be presenting an overview of AeroFS file system, advantages and challenges of a high-availability file system, and examine the inner workings of AeroFS's core syncing algorithm.

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.

A panel organized by the CS Club on how feminism manifests itself in STEM, specifically CS and Engineering.
Panelists are Dr. Prabhakar Ragde, Swetha Kulandaivelan, and Filzah Nasir. Moderated by Fatema Boxwala.
Due to battery trouble, the first few minutes of audio were lost. The panelists were introduced as Prabhakar from the School of Computer Science, Swetha from 4A Mechanical Engineering, and Filzah as an Engineering grad student.
Sample questions from the panel section are:
- Filzah and Swetha, can you expand on how Engineering tries to keep its curriculum grounded in reality?
- Why would an Engineering 101 instructor tell the class to design urinals?
- Prabhakar, how can men in STEM help women get their voices heard?
<!-- -->
Sample questions from the audience after the panel: - As a woman in CS, how do I know I wasn't hired to meet a diversity target?
- Filzah, you mentioned that "getting to 50%" isn't what you're interested in. Can you expand on that?
- An admittedly selfish argument I've seen on Reddit asks why we should cooperate with marginalized communities when we're not significantly affected by them? (Response at 10 minutes into questions)
- Prabhakar, how has CS changed since you were an undergrad?
<!-- -->
A statistical errata: The Math faculty proportionally gives offers of admission to the 25% of women that apply, and there are no significant disproportionate dropout rates.

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.

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.
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!

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.
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.

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.

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.

I demonstrate the architecture on Progressive Raven's Matrices (RPM), a test of general fluid intelligence.

The traveling salesman problem is easy to state: given a number of cities along with the cost of travel between each pair of them, find the cheapest way to visit them all and return to your starting point. Easy to state, but difficult to solve. Despite decades of research, in general it is not known how to significantly improve upon simple brute-force checking. It is a real possibility that there may never exist an efficient method that is guaranteed to solve every instance of the problem. This is a deep mathematical question: Is there an efficient solution method or not? The topic goes to the core of complexity theory concerning the limits of feasible computation and we may be far from seeing its resolution. This is not to say, however, that the research community has thus far come away empty-handed. Indeed, the problem has led to a large number of results and conjectures that are both beautiful and deep, and on the practical side solution methods are used to compute optimal or near-optimal tours for a host of applied problems on a daily basis, from genome sequencing to arranging music on iPods. In this talk we discuss the history, applications, and computation of this fascinating problem.

Infra sound refers to sound waves below the range of human hearing. Infra sound comes from a number of natural phenomena including weather changes, thunder, and ocean waves. Common man made sources include heating and ventilation systems, industrial machinery, moving vehicle cabins (air, trains, cars), and energy generation (wind turbines, gas plants).
In this talk Richard Mann will present equipment he has built to measure infra sound, and analyse some of the infra sound he has recorded.
Note: In Winter 2016 Richard Mann will be offering a new course, in Computer Sound. The course will appear as CS489/CS689 ("Topics in Computer Science"). This is a project-based course (60% assignments, 40% project, no final). Details at his web page, [\~mannr](<http://www.cs.uwaterloo.ca/~mannr>).

Programming systems that obey hard real-time constraints is difficult. So is programming multiple CPUs that interact to solve a single problem.
On rare occasions it is possible to mix two difficult problems to create one easy problem and multi-CPU real-time is, on the face of it, just such an occasion. Give each deadline its own CPU and it will never be missed. This intuition is, unfortunately, incorrect, which does not, however, prevent it being tried in many real-time systems.
For three decades, fourth year students have been exploring this problem in CS452, using multiple tasks (virtual CPUs) running on a single CPU. It is now time to consider whether modern developments in CPU architecture make it possible to use multiple CPUs in CS452 given the practical constraint of a twelve week semester.
This talk will describe the nature of computation typical of real-time systems, architectural solutions currently employed in the course, and possible architectures for multi-CPU systems.

You've got a game, but you didn't write it. You're running it by emulating the machine it was meant to run on, and the machine it was meant to run on never had support for networking. Now, you want to play with your friend, over the Internet. Oh, and it's not acceptable to incur any latency between your controller and the game while we're at it. Surely that can't be possible, right? Wrong. This talk will discuss the re-emulation technique for netplay used commercially by a system called GGPO and freely in an emulator frontend called RetroArch, and how similar techniques can be applied to make networking work in other scenarios it was never meant for. This will be an unprepared, impromptu talk with no slides, so it should either be a fascinating dive into a little-heard-of technique, or an impenetrable mess of jargon and algorithms. Either way, it should be fun. Professor Richards is the maintainer of the netplay infrastructure for RetroArch, a popular emulator frontend for multiple platforms.

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.

An ideal computer audio system should faithfully reproduce signals of all frequencies in the audible range (20 to 20,000 cycles per second). Real systems, particularly mobile devices and laptops, may still produce acceptable quality, but often have a limited response, particularly at the low (bass) frequencies. Sound/acousic energy refers to time varying pressure waves in air. When recording sound, the acoustic signal will be picked up by microphone, which converts it to electrical signals (voltages). The signal is then digitized (analog to digital conversion) and stored as a stream of numbers in a data file. On playback the digital signal is converted to an electrical signal (digital to analog conversion) and finally returned as an acoustic signal by a speaker and/or headphones. In this talk I will present open source software (Octave/Linux) to measure the end-to-end frequency response of an audio system using the Discrete Fourier Transform. I will demonstrate the software using a standard USB audio interface and a consumer grade omnidirectional microphone. This is joint work with John Vanderkooy, Distinguished Professor Emeritus, Department of Physics and Astronomy.

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.

The interactive proof system model of computation is a cornerstone of complexity theory, and its quantum computational variant has been studied in quantum complexity theory for the past decade. In this talk I will discuss an exact characterization of the power of quantum interactive proof systems that I recently proved in collaboration with Rahul Jain, Zhengfeng Ji, and Sarvagya Upadhyay. The characterization states that the collection of computational problems having quantum interactive proof systems consists precisely of those problems solvable with an ordinary classical computer using a polynomial amount of memory (or QIP = PSPACE in complexity-theoretic terminology). This characterization implies the striking fact that quantum computing does not provide any increase in computational power over classical computing in the context of interactive proof systems.
I will not assume that the audience for this talk has any familiarity with either quantum computing or complexity theory; and to be true to the spirit of the interactive proof system model, I hope to make this talk as interactive as possible -- I will be happy to explain anything related to the talk that I can that people are interested in learning about.

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 [here](<http://mirror.csclub.uwaterloo.ca/csclub/alex-ionescu.pdf>).
**Biography**
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 security to various companies.

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.

How do we make dynamic languages fast? Today, modern Javascript engines have demonstrated that programs written in dynamically typed scripting lan- guages can be executed close to the speed of programs written in languages with static types. So how did we get here? How do we extract precious type information from programs at runtime? If any variable can hold a value of any type, then how can we optimize well?
This talk covers a bit of the history of the techniques used in this space, and tries to summarize, in broad strokes, how those techniques come together to enable efficient jit-compilation of dynamically typed programs. To do the topic justice, Kannan Vijayan will be talking the Monday and Tuesday March 9th and 10th.

Does your program have an overflow error? Will it work with all inputs? How do you know for sure? Test cases are the bread and butter of resilient design, but bugs still sneak into software. What if we could prove our programs are error-free?
Boolean Satisfiability (SAT) solvers determine the ‘satisfiability’ of boolean set of equations for a set of inputs. An SMT solver Satisfiability Modulo a Theory) applies SMT to bit-vectors, strings, arrays, and more. Together, we can reduce a program and prove it is satisfiable, or provide a concrete counter-example. The implications of this are computer-aided reasoning tools for error-checking in addition to much more robust programs.
In this talk Murphy Berzish will give an overview of SAT/SMT theory and some real-world solution methods. He will also demonstrate applications of SAT/SMT solvers in theorem proving, model checking, and program verification.
There are both .pdf slides and a .mp4 recording of the talk. Code samples and spellings of terms are in the slides, consider following along with the slides.

Could you write a good image recognizer for a 100 MHz mobile phone processor with 1 MB heap, 320x240 image, on a poorly-optimized Java stack? It needs to locate and read two-dimensional barcodes made up of square 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.

Concurrency is hard. Well maybe not hard, but it sure is annoying to get right. Even the simplest of synchronization tasks are hard to implement correctly when using synchronization primitives such as locks and semaphores.
In this talk we explore what Software Transactional Memory (STM) is, what problems STM solves, and how to use STM in Haskell. We explore a number of examples that show how easy STM is to use and how expressive Haskell can be. The goal of this talk is to convince attendees that STM is not only a viable synchronization solution, but superior to how synchronization is typically done today.

Do spam filters work? Which is the best one? How might filters be improved? Without standards, one must depend on unreliable evidence, such as subjective impressions, testimonials, incomparable and unrepeatable measurements, and vendor claims for the answers to these questions.
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 filter was 99-percent accurate, would you believe me? Would you know what I meant? Would you be able to translate that 99-percent into the risk of losing an important message?

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.

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 Microsoft."
**Biography:** Stallman has received the ACM Grace Hopper Award, a MacArthur Foundation fellowship, the Electronic Frontier Foundation's Pioneer award, and the Takeda Award for Social/Economic Betterment, as well as several honorary doctorates.
The Question and Answer session (starting shortly after the hour and half mark) posed a number of interesting questions including, "Do you support the Creative Commons license?" and "Can I use ATI and NVIDIA drivers because Mesa isn't nearly as complete?".
The talk is only available in Ogg Theora, in keeping with Richard Stallman's wishes.

Bill Gates in his article "A Robot in every home" in the Scientific American describes how the current robotics industry resembles the 1970's of the Personal Computer Industry. In fact it is not just Microsoft which has already taken a step forward by starting the Microsoft Robotics studio, but robotics researchers around the world believe that robotics and automation systems are going to be ubiquitous in the next 10-20 years (similar to Mark Weiser's analogy of Personal Computers 20 years ago). Natural User Interfaces (NUIs) are going to revolutionize the way we interact with computers, cellular phones, household appliances, automated systems in our daily lives. Just like the GUI made personal computing a reality, I believe natural user interfaces will do the same for robotics.
During the presentation I will be presenting my ongoing software project on natural user interfaces as well as sharing my goals for the future, one of which is to provide an NUI SDK and the other to provide a common Robotics OS for every hardware vendor that will enable people to make applications without worrying about underlying functionality. If time permits I would like to present a demo of my software prototype.

What is the typical monitor resolution of a GIMP user? How many monitors do they have? What size images do they work on? How many layers are in their images? The answers to these questions are generally unknown: no means currently exist for open source applications to collect usage data. In this talk, Professor Michael Terry will present ingimp, a version of GIMP that has been instrumented to automatically collect usage data from real-world users. Prof. Terry will discuss ingimp's design, the type of data we collect, how we make the data available on the web, and initial results that begin to answer the motivating questions. ingimp can be found at http://www.ingimp.org.
The slides from the talk are available here: [ingimp\_uw\_csc\_talk\_6\_27\_2007.pdf](<http://mirror.csclub.uwaterloo.ca/csclub/ingimp_uw_csc_talk_6_27_2007.pdf>).

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.
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.
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!
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.
I will defend this viewpoint with examples and demonstrations from electrical engineering and from classical mechanics.
