Free Software I Have Found to Be Useful:
I am very much a fan of free software (by which I mean software I can
legally obtain and/or use without paying for) I am an even bigger fan
of open source software (although not all of these links are to open
source programs). I have noticed that a lot of the time a challenge
with using free software is finding it in the first place, and for that
reason I have compiled a list of links and brief descriptions of things
I have found useful. Some names used here may be trademarks of their
respective owners.

This free vector graphics package has been a lifesaver more times than
I can count. I use it pretty much exclusively to produce drawings to
demonstrate things for papers.
Has most of the same functionality as Matlab, but is available for
free. Has proven very useful for my netbook where I do not have Matlab
installed.
This image manipulation program has proven very useful on many
occasions. I very often use it for resizing and cropping images before
putting them into a paper.
A high level program for creating LaTeX documents. I have found this
very useful for writing longer documents without having to remember all
of the LaTeX commands. It has a very intuitive interface and is nice
especially for someone who is just starting with LaTeX.
A lower level LaTeX editing program for editing the code directly. I
have found this very useful in some cases, I find that it is useful to
have both a lower level program for editing the code directly as well
as a higher level program such as LYX.
A very nice program for graphically exploring the universe of the
Mandelbrot and Julia sets. I haven't found much use for it
professionally, but it is a lot of fun to use.
A web design program which is intuitive and easy to use, and allows you
to easily edit the html code directly if necessary. This is the program
I used to create this webpage.
A website which allows one to do similar mathematical calculations to
what Wolfram Mathematica can do, but for free. The calculations time
out, so this cannot be used for heavy computation, but I have found it
very nice if one uses it as a more powerful graphing calculator. It is
also very useful for explain things to students.
