I ranted a few years ago about rate hikes disguised as fees or taxes, but Verizon's unabashed deceptive practices still gets me all worked up. Last year, the FCC decided that Verizon didn't have to pay the Universal Service Fund fee any more, but that didn't stop them from charging for it anyway. What galls me is their explanation of the fee the...

Continuing in the extremely sporadic series on the format of resources, today we'll take a look at accelerator tables. This topic is so simple, I'll cover both 16-bit and 32-bit resources on the same day! In 16-bit Windows, the format of an accelerator table resource was simply an array of structures.

The New Yorker reported some time ago on how Navteq gathers map data. This story reminded me that, at least as of a few years ago, Navteq listed the driveway of a colleague of mine as a through road. Drivers came up to his driveway, realized that they've been hoodwinked, and spun their wheels in the gravel in frustration on their way out. He tol...

There are many functions that return strings called "display names". And the only thing you can do with display names is display them. Don't assume that the string actually means anything, because it doesn't. Theoretically, a function like could be implemented as and your program should still work. (Of course, this is merely a ground rule. S...

Jason Doucette asks how slow a machine has to be to be considered a . The answer: Pretty darned slow by today's standards.
