Programming From Scott Orgera, your About Programming Editor In honor of the frigid temperatures gripping most of the United States this winter, this week's newsletter shows you how to calculate wind chill using PHP - among other things. Brrr! Can You Sell Open Source Software? Maybe it's because "open source" describes at least two separate things -- a way of licensing software as well as a strategy for creating it -- but there's often confusion around what open source software is and how exactly it can be used. You've probably heard people ask where open source software can run, how to get involved in open source software projects, and even how to start an open source software project, but there's one question more than any other that seems to really stump people: Can you sell open source software?

This got me thinking about wind chill. You see the temperature alone (in the -20 to 0 range) isn't cold enough to shut down everything. It's the addition of the wind that makes the temperatures feel so terribly frigid and dangerous. This inspired me to write a little program to calculate the wind chill.

Another type of collection of variables is the hash, also called an associative array. A hash is like an array in that it's a variable that stores other variables. However, a hash is unlike an array in that the stored variables are not stored in any particular order, and they are retrieved with a "key" instead of by their position in the collection.
