Hardware backwards compatibility

Backwards compatibility applies not only to software. It also applies to hardware. And when hardware goes bad, the software usually takes the blame. The HLT instruction tells the CPU to shut itself down until the next hardware interrupt. This is a big win on laptops since it reduces power ...

Windows XP ships with a number of icon overlays. The black clock is particularly baffling because you sometimes see it even if your system is not equipped with Hierarchical Storage Management. When this happens, it's because some program (...

Sometimes you run into a conflict where you need the controls laid out in one Z-order to get hit-testing to work, but need a different order to get keyboard TAB order working. For example, consider this dialog template, which has been simplified for expository purposes. The...

Windows brings out the Rorschach test in everyone
Windows brings out the Rorschach test in everyone

It seems that no matter what you do, somebody will get offended. Every Windows 95 box has an anti-piracy hologram on the side. The photographer chose his infant son as his model, since the human face is very hard to copy accurately. The baby sits next to a computer, and as you turn the hologram...

I've decided to change the color scheme to match my latest knitting project:  A pumpkin hat. (Previous food-themed hats were raspberry and eggplant.) I just got a call from the yarn store that the yarn for my sweater has come in, and I can't wait...

What is in the "Windows 95 Special Edition" box?

At the Windows 95 Launch and at various other marketing events, guests were given a copy of "Windows 95 Special Edition". What is so special about the box? Answer: The box. The contents of the box are exactly the same as a regular copy of Windows 95. The only thing special ...
