Unexpected consequences of writing a book: Public appearances

Raymond Chen
One of the consequences of being a minor book author is that you can't be a private person any more; you're automatically a public personality. If somebody asks you for an interview, you can't just reject it as a matter of principle. You're now doing it not for yourself but in the service of your book. (Major authors might be able to get ...

The cost of continuously-visible affordances with dynamic states

Serge Wautier asks, "Why are the copy/cut/paste buttons not disabled when there's nothing to copy/cut/paste?", noting that the back/forward buttons do disable themselves when navigation is not possible in that direction. To get to this question, we'll first go back in time a bit to a world without toolbars. In those early days, these dynamic ...

2006 storm aftermath: A look back

It's been about a month since the windstorm that brought the Seattle area to a standstill. Puget Sound Energy has posted a recap of the storm, including what I consider to be a wonderful euphemism: We thank those customers who called to update us with valuable outage status information. Translation: "We would like to acknowledge all the ...

Email tip: Choose a subject line that is meaningful to the recipient, not to the sender

Presumably you want the recipient to read the message. That's why you sent it. It would behoove you to select a subject line which conveys to your reader the purpose of your message. Otherwise your reader is likely to ignore it for being too vague and uninteresting. Here are some actual bad subject lines I've seen. Suppose your Inbox had a...

Iced-over roads + people who can't drive = very expensive (and dangerous) game of billiards

Unbelievable video of people in Portland, OR who should know better trying to drive down an icy road. (Direct WMV link. Interview with the person who shot the video, but you're going to have to put up with the inane local news-anchor chatter. That last link includes images of cars that, yup, struck the fire truck.) It's as if these people ...

Should all windows appear in the taskbar?

January 17, 2007 Jan 17, 2007 01/17/07
Raymond Chen
No new content today, just some follow-up discussion on the topic of windows that don't appear in the taskbar. The rules for which windows appear in the taskbar have been documented in MSDN for years, so changing the rules now would mean doing so after the game has ended. Consequently, this is not the sort of change that can be made lightly...

One Armstrong = 13.5 mph

Raymond Chen
Out of curiosity, I wanted to know how fast Tour de France riders go up l'Alpe D'Huez, the legendary mountain climb. Using information from the Wikipedia page, I calculated that Lance Armstrong's 2004 ascent had an average speed of approximately 13.5 mph (22 kph). Consequently, I invented the Armstrong, a unit of bicycle velocity, ...

EnumChildWindows already enumerates recursively

January 16, 2007 Jan 16, 2007 01/16/07
Raymond Chen
I often see people write code that goes something like this: The intent here was to perform the operation on all the windows in a window tree by operating on the root, then operating on each of the children. Operating on the children is in turn performed recursively, so that we eventually see every window in the tree. Except that if you ...
