The movie This Is Spinal Tap introduced the world to the phrase going to eleven. The people over at Windows Media Player were not immune to its charms, alluding to the catchphrase in their advertising campaign. Back in Windows 95, I know that there was at least one person who lobbied the multimedia team to give the Volume Control ...

In response to the recent passing of chess celebrity Bobby Fischer, the Associated Press published an article titled Excerpts from Fischer-Spassky Games. The article consists of excerpts from the organization's coverage of the so-called Match of the Century in 1972. But given the title, I wondered whether the article had merely gone like ...

One of my colleagues has a degree in economics, and sometimes it manifests itself in strange ways. My colleague moved to a new apartment building and rented a parking space in the building's garage.

Back in 2002, I noted with some fascination the opening of Jerry Springer: The Opera in London. (Here's coverage in the New York Times. If you're going to skim the article, at least skim all the way to the end, wherein the real Jerry Springer is asked for his opinion.) Opening with the onstage studio audience chanting "Jer-ry! Jer-ry!", a ...

But what if you want to know when the window is shown, including in the cases where you don't get ? The message is sent at the end of the window state change process. It sort of combines the other state change notifications, , , and . ...
