The Mac community this week found itself debating an updated Apple Inc. Knowledge Base article that urged users to run antivirus software -- until the document was yanked. Computerworld's Michael DeAgonia breaks the brouhaha down for you.

For years, architects have gone to great lengths to protect their buildings from marauding skaters. But as aesthetic trends move toward folded planes that transition seamlessly from wall to ceiling and back to wall, designers have been looking to their former adversaries for a lesson in flow.

"We have this fascination with buildings becoming topography," says Alejandro Zaera-Polo, a partner at London's Foreign Office Architects, "and skateboarders have that physical experience." So for a park in Barcelona, his firm extended paving stones up the sides of small hills—to shield vegetation from salty sea breezes. At least that's what it told city officials. But skaters got the message. The resulting quarter-pipe landed on the March 2006 cover of Transworld Skateboarding.

Architect Zaha Hadid shares the love. She wanted her Phaeno Science Center in Germany to be an all-inclusive venue for pedestrians and skateboarders alike. Liability issues prevented skate-park designation—though you'd never guess it from the YouTube videos of pro skaters "visiting" the museum. "We design spaces that are flowing and continuous, and—just by coincidence—skateboarders look for that kind of continuity," Dillon Lin, an architect (and skater) at Hadid's firm, says with a wink.

And though the new Oslo Opera House (shown here) was inspired by the image of two glaciers colliding, the architects at Snøhetta didn't call on glaciologists to help fine-tune the details. They enlisted real experts in twisted planes: skateboarders. "We spoke to them about surface textures and the areas they prefer," architect Simon Ewings says. His firm followed up the conversation with a statement in stone.

Snøhetta used different finishes of marble to guide skaters looking for rideable surfaces. Acoustically sensitive parts, like above the auditorium, got rough marble that's unpleasant to wheel over. But other areas silently beckon skaters. Surfaces rise up all over the place to become ledges, curbs, and benches—like the jagged facets of a glacier (or skate park). One particularly tempting spot is a 3-foot-wide railing of smooth stone. Snøhetta architect Peter Dang is, ahem, absolutely sure it's skatable. "Just make sure to fall toward the inside," he advises.

Tricked Out

The new Oslo Opera House is much more than a temple to the vocal arts. It's a palace of thrash, with as many gnarly facets as the best skate parks. Here are some key features and suggested moves.

The proposed acquisition of Macromedia by Adobe is not a done deal. Both companies are under the scrutiny of the SEC, and it must also be approved by stockholders. While Macromedia/Adobe gives this process three to nine months, some industry analysts feel that is being overly optimistic. But assuming that all is goes as planned, Macromedia will cease to exist. Everything will be in the Adobe name and with the Adobe interface.
