The Sounds of Tech Past 231

itwbennett writes "If you're of a certain generation, the screech of a modem, the stuttering song of the dot matrix printer, and the wet slap of a mimeograph machine can transport you to simpler (or at least slower) times. JR Raphael has rounded up 20 tech sounds on the brink of extinction for your listening torture. We're only sorry we don't have smell-o-vision to bring you that sweet mimeograph scent."

Should Cities Install Moving Sidewalks? 698

Posted by timothy from the that-and-bicycle-elevators dept.
theodp writes "The real problem nowadays is how to move crowds,' said the manager of the failed Trottoir Roulant Rapide high-speed (9 km/h) people mover project. 'They can travel fast over long distances with the TGV (high-speed train) or airplanes, but not over short distances (under 1 km).' Slate's Tom Vanderbilt explores whether moving walkways might be viable for urban transportation. The first moving sidewalks were unveiled at Chicago's 1893 Columbian Exposition, and at one point seemed destined to supplant some subways, but never took root in cities for a variety of reasons. Vanderbilt turns to science fiction for inspiration, where 30 mph walkways put today's tortoise-like speed ranges of .5-.83 m/s to shame. In the meantime, Jerry Seinfeld will just have to learn to live with 'the people who get onto the moving walkway and just stand there. Like it's a ride.'"

You are correct that it's a good rule of thumb to just never use identifiers that start with an underscore, but there are exceptions.

From http://web.archive.org/web/20040209031039/http://o akroadsystems.com/tech/c-predef.htm#Groups:

Respect that first entry in the table below: never make up any identifier that starts with an underscore.

(Actually, you can legally use an identifier that starts with an underscore if the second character is a lower-case letter or a digit, and the identifier is used inside a function or a function prototype or as a structure member or label. Easier just not to use leading underscores!)

The parent post uses them inside a function and the second character is lower-case.
