Greg Wright will talk about the design of the Wheeler library, which
adds the ability to do symbolic algebra to Haskell.
Since the earliest days of programming, symbolic algebra has been a
laboratory for the development of functional programming. The talk
will cover a bit of this history to explain basic aspects of the
library: which data structures are used (and why), and the design
choices made to allow symbolic expressions work smoothly with
ordinary arithmetic expressions. A particular strength of the library
is its ability to work with non-commuting objects (for example,
matrices); how this was done will be discussed.
Another key goal of Wheeler is extensibility, allowing users to add
their own mathematical objects. The talk will show how this runs
smack into the so-called "Expression Problem". The second half of the
talk will look at a couple approaches to solving the expression
problem, seeing how close we can get to the goal of extending the
library while still understanding our code.
To show this isn't all just blowing smoke, the Wheeler library will
be demonstrated on a hard real-world problem. As an added bonus, at
no extra charge, the talk will be (mercifully) almost monad free!

Greg Wright is an experienced Haskell hacker, who has worked on a
variety of projects in telecommunications, signals, embedded systems,
and wireless design. He's also an engaging speaker who has presented
multiple times at the Commercial Users of Functional Programming
conference (latest video

Unfortunately this venue has stronger restrictions on attendees
than our usual spot at Pivotal. See my edit to the description.

The NY Haskell Users Group is for all programmers either interested in or
experienced with the Haskell programming language. We want to build a
community of Haskell developers in the New York area that can share
knowledge, projects, and experience, and to generally foster and
encourage strongly typed functional programming, in all languages, all
settings, and all industries. Our events will center around talks, but we
intend to have other sorts of activities, including social hours, code
workshops, and perhaps, eventually hackathons.
