As developers, we often shriek a little whenever a new operating system is released. Our most common question is “will my application run?” Enhancements in compatibility have made this question a mute point. Now that we don’t have to spend as much time fixing our applications, we can concentrate on improving them.
As .NET developers, we have often been left behind on major operating system integrations, unless we were willing to dive into unmanaged code. Windows 7 brings new salvation for .NET developers, and it comes in the form of the Windows 7 API Code Pack for......

Operator Overloading: A demonstration using matrices (Matt Gertz)
Published 07 May 07 10:51 AM
Over a decade ago, before I joined Microsoft, I was a doctoral candidate at Carnegie Mellon studying robotics. One of the things that you had to do to get into the doctoral program was pass a qualifier test (“the qual”), which was a three-hour oral examination at the conclusion of the Master’s program. My qual was, without a doubt, the most grueling experience I’d ever gone through – rougher than my actual dissertation several years later, and certainly rougher than a Microsoft interview. (“You just want me to write a program to shuffle a deck of cards? I think I can manage that…”) For the “qual,” it was common knowledge that you’d be expected to memorize and write out on command just about every formula known to mankind about the physics of robotics. To prepare, I wrote down 78 equations that I thought would be fair game during the exam, and I spent on......
