Looking for TeX? Joshua is a (somewhat experimental) mirror of the Comprehensive TeX Archive Network. That means that all (well, almost all) of the TeX material that you need can be found here. The binaries to run TeX, the TeX and LaTeX style files, and the documentation are all here. In case there is too much here, you can also search for TeX files. On that page you can also search Graham William's Catalogue, and there are a few FAQ-type links. (Joshua. is experimental in that I may be trying out stuff to put up on the main CTAN site.)
Saint Michael's Mathematics Department? This is the home machine for the Saint Michael's College Mathematics Department. There is a great deal of information on our program. Also here is our department's current course schedule. You may also want to check out the overall Saint Michael's College home page.
My Linear Algebra book? Here you can find a downloadable copy of my Linear Algebra, an undergraduate text. There is an in-depth description on that page, but briefly: this text features standard coverage (linear reduction, vector spaces, linear maps, determinants, and eigenvalues), proves things but carefully covers the needed computations also, and has extensive exercises, all with worked-problem answers. It has been class-tested a few times, and is suitable for a person to use as a main text in a class, or as a supplemental book, or for self-study. I think it's pretty good!
Me, Jim Hefferon? My page. Here you can find materials for my classes, such as syllabii and some slides from lectures. Old exams of mine are here, so if you are taking a class with me you can use them to give you a hint of what you might see. I've also included some business such as office hours. Finally, what would a home page be without some good links? I've got some for TeX and LaTeX, for Linux, and for a few other things.
Open-sourced and Free software is a great idea. We can build on good work that other folks have already done, and not just make the fifty-first implementation of something.
