The Glistening Ruby: An interpreted scripting language with an object-oriented heritage

September 30, 2005 8:00 pm | by John R. Joyce, Ph.D. | Articles | Comments

To wrap up our programming topics mini-arc, I'd like to invite you to investigate a relatively new interpreted programming language, Ruby. Unlike many other scripting languages, it was designed from the ground up to be object-oriented. The impact of this object-oriented heritage will be obvious as you examine its functionality. Designed by Yukihiro Matsumoto, a.k.a. 'Matz', in Japan, it was first released on an unsuspecting world in 1995.

Abuzz About ZigBee

Low-power self-organizing data networking Bill Weaver, Ph.D. I recently purchased a 2006 Toyota Corolla with the goal of reducing the frequency of trips to my local filling station. In time, I may begin to miss my close friends behind the counter, but one thing I was startled to miss right away was the throttle cable to the Corolla's VVT-i engine. Similar to the "fly-by-wire" transformation experienced by the U.S. Air Force, "drive-by-wire"...

As with most things, the more familiar are what we usually feel comfortable dealing with on a daily basis. In this case, although there are probably thousands of software packages pertinent to data analysis worldwide, we tend to concentrate on the ones from the U.S. It is therefore a nice change to see what else is out there and review a package from our colleagues in Britain, Australia and New Zealand.

Simulating 3-D flames with unmatched accuracy Horst Simon Remember when "sticker shock" referred to the price of a new car — not the cost of filling the gas tank? Given rising oil prices, getting the most efficiency out of a gallon of gas has implications ranging from personal finances to national policy. Investing in combustion research at national laboratories and universities

Wetness-defying Water?

September 30, 2005 8:00 pm | News | Comments

Now you can extend that truism about oil and water to water and itself. Water and water don't always mix, either. The textbooks say that water readily comes together with other water, open arms of hydrogen clasping oxygen attached to other OH molecules. This is the very definition of “wetness”…
