A customer wanted to know how they could find out the directory that the user dropped a file onto. As we already noted, users can drop files onto things other than directories, so the question itself comes with incorrect hidden assumptions. This is another one of those cases where you have to ask the customer, "What are you really trying to do?" ...

Quantum Hoops is a new documentary which follows the college basketball program at the California Institute of Technology through its 2007–2008 season.

When talking about why people buy computers, there are two broad categories, "replacement computers" (those which replace an older machine being retired) and "new placement computers" (those which do not).

(When I mentioned to one of my colleagues that I paid a brief visit to his native country, he replied, "I hope it went okay." Off my confused expre...

This is a holdover from very early versions of the C language where structure tags, union tags, and typedefs were kept in the same namespace. Consequently, you couldn't say .

March 25th is the Feast of The Annunciation according to the Catholic Church calendar, the day on which the archangel Gabriel announced to Mary that she would conceive a child, the Son of God. Why March 25th? The date was arrived at by the follo...

When you go through Windows header files, you'll see types with names , , , and so on. What's the difference between these types and the uncapitalized ones? Well, there isn't one any more.
