Learning (the basics of) calculus online?

So, in the Coursera course I'm taking, there is a bit in one of the lectures where the instructor basically says

"""
Ok, so dealing with this problem requires some fancy math. If you're not familiar with how to deal with this kind of problem, you have two options:

1) Take a discrete mathematics course.

2) Do it the easy way! You can just convert these problems to integrals and solve them with calculus! Ta da!!
"""

*sigh*. This from a class that only requires "some math".

Ok, confession time: I've been in IT for well over a decade. I hang out with MIT folk without completely failing to fit in. And yet, the last time I touched calculus was when I failed it in 1997. This is (in part) why I consider myself an "IT person", but not a computer scientist.

BUT. In 1997 I was a lot less together than I am now, and I'm a little curious as to whether I could tackle it better now.

I know at least a few people out there are newfangled alt-ed types and/or mathy types, so question:

If I decided to, just for kicks, take another stab at integrals and see if I could get it, is there some interactive or otherwise novel ed 2.0 thing out there online that you'd recommend I look at, or is this one of those things were we ultimately come back to "suck it up and read a textbook"?

BOS PSA: West Nile Virus

I don't want to contribute to or encourage undue hysteria, but this email from a local mailing list seems pretty straightforward and level-headed:

"""
You may have already heard that a Cambridge resident was diagnosed August 15th with West Nile Virus (WNV), a mosquito borne disease. A second Cambridge resident was diagnosed early this week and infected mosquito pools of water have been found in the city.

Be smart about avoiding mosquito bites - its not that hard. Use insect repellent especially dawn, dusk and at night and keep your exposed skin to a minimum. The Recreation Department is providing repellent at its events on Russell Field.

You can also help eliminate mosquito breeding grounds by not having standing water on your property. That includes water in pot saucers, rain barrels, pet bowls, bird baths, clogged rain gutters and kiddie wading pools.

The symptoms of WNV are flu-like but most people don't have symptoms.

If you want to stay updated ask to be added to the westnile@cambridgema.gov email.
