About three weeks ago, I splurged and ordered myself a Kindle 2.  I had bounced back and forth between wanting one and not but finally convinced myself that it was time to add another gadget to my repertoire.  And let me say, I love it!!  To alleviate any guilt over spending that kind of [...]

I was having a problem when using Camtasia Studio to do a screen capture of an algebra lecture.  On my laptop, the capture works just fine but on my desktop it was very jumpy.  For those who don’t know, I use a Wacom Tablet, Microsoft OneNote and Camtasia to produce a series of videos [...]

An awesome new feature was recently announced by Google for the contact management tools in Gmail.  If you have multiple contact entries for the same individual in Gmail you can now easily merge them into one.

Be careful what you say.  You MUST assume EVERYONE is listening.

Well over two years ago on this blog (have I really been around that long?), I posted a link to a story that Sudoku had been solved.  (The original link to the Math-Forge Story is broken, so here in alternative version of the story.) While just about every computer scientist and programmer I know [...]

I gave a presentation today to my colleagues at WBU in order to train them on teaching an online mathematics course.  We have offered College Algebra online for the last year and, so far, I have been the sole instructor.  I developed a series of lecture videos and notes for the students.  We are now [...]

In my Fall course of Math Models, I have three groups working on projects to finish up the semester.  One of the groups have an assignment to explore a model of the spread of a forest fire.  The assumptions are that the trees are on a rectangular grid, or a lattice.  The time is a [...]
