Ein deutscher Blogger namens Tony schrieb dass Robert Scoble is gaining on Steve Ballmer. Mit anderen Worten, dass eine Google-Suche nach "Robert Scoble" ungefähr 172.000 Seiten findet, während eine Google-Suche nach "Steve Ballmer" ungefähr 302.000 Seiten zeigt. Er fragte, ob jemand einen anderen Microsoft-Angestellten finden kann...
If you select say five files and then right-click them and choose "Print", they tend to print in a random order. Why is that? The shell invokes the Print verb on each file in turn, and depending on how the program responsible for printing the document is registered, one of several things can happen. These three ways of registering print act...
The RunAs program demands that you type the password manually. Why doesn't it accept a password on the command line? This was a conscious decision. If it were possible to pass the password on the command line, people would start embedding passwords into batch files and logon scripts, which is laughably insecure. In other words, the feature is ...

"How can I find out how many outstanding references there are to a shared memory object?" Even if there were a way to find out, the answer you get would be instantly wrong anyway because th...

Then if you unplug it and replug it into a different USB port, Windows gets a bout of amnesia and thinks that it's a completely different device instead of using the settings that applied when you plugged it in last time. Why ...
I had previously written on how you can retrieve the text under the cursor, and you may have noticed that it produces mixed results. It works great with some programs but not with others. It depends on the program in question. Some programs were written with greater attention to supporting screen readers than others. Internet Explorer, for examp...
A colleague of mine nominated this code for Function of the Year. (This is the same person who was the first to report that a Windows beta used a suspect URL.) I have to admit that this code is pretty impressive. Of all the ways to check the operating system, you have to agree that sniffing at an undocumented implementation detail of memory-mapp...
