I was going to write about why C# doesn't have "const", but Stan Lippman already discussed this in A Question of Const, so now I don't have to. (And another example of synchronicity: After I wrote up this item and tossed it into the queue, Eric Gunnerson took up the topic as well.
Windows lets you hibernate the entire machine, but why can't it hibernate just one process? Record the state of the process and then resume it later. Because there is state in the system that is not part of the process. For example, suppose your program has taken a mutex, and then it gets process-hibernated. Oops, now that mutex is abandoned...

Ctrl+Alt is a special key combination used for entering extended characters.
When you're dealing with application compatibility, you discover all sorts of things that worked only by accident. Today, I'll talk about some of the "creative" ways people mess up the IUnknown::QueryInterface method. Now, you'd think, "This interface is so critical to COM, how could anybody possible mess it up?" Forgetting to respond to IUnk...
David Cumps discovered that certain text files come up strange in Notepad. The reason is that Notepad has to edit files in a variety of encodings, and when its back against the wall, sometimes it's forced to guess. Here's the file "Hello" in various encodings: This is the traditional ANSI encoding. This is the Unicode (little-endian) ...
