Who Protects The Internet?

For the past five years, John Rennie has braved the towering waves of the North Atlantic Ocean to keep your e-mail coming to you. As chief submersible engineer aboard the Wave Sentinel, part of the fleet operated by U.K.-based undersea installation and maintenance firm Global Marine Systems, Rennie–a congenial, 6’4″, 57-year-old Scotsman–patrols the seas, dispatching a remotely operated submarine deep below the surface to repair undersea cables. The cables, thick as fire hoses and packed with fiber optics, run everywhere along the seafloor, ferrying phone and Web traffic from continent to continent at the speed of light.

The cables regularly fail. On any given day, somewhere in the world there is the nautical equivalent of a hit and run when a cable is torn by fishing nets or sliced by dragging anchors.

Kevin Rose: Apple to Cure Pre-Ness Envy with Cut and Paste

Wired – We don’t know if Digg’s Kevin Rose is diddling with us, but at a live session of the Diggnation show at South by Southwest he offered the scoop on the new iPhone 3.0 operating system, to be officially detailed on Tuesday.

The new update will bring, at last, copy and paste, Kevin says. It works thusly: You double tap a word and it gets magnified, much like the cursor-placing magnification in the current version. You then pinch to choose the highlighted text (which is apparently indicated by a set of quote marks). Last, you choose from a button: cut, copy or paste.

In the video, the crowd goes wild. Rose then tells us “No background apps.” Sensible, as they would be battery killers. Apple is also bringing parity with the Pre, adding everything that Palm’s yet-to-be released new handset will have.

Rose also reports that there will be “no video in this release” (recording, of course — we already have a video player).

Steven Levy’s Ode to Vintage Ports — Farewell, Sweet FireWire

Wired – At one point during last October’s introduction of the latest MacBook laptop, Steve Jobs made a telling remark: “We are just as proud of things we leave out.” He was talking about toxic chemicals. But when the MacBook’s specs were detailed later that day, it became clear that Apple had left something else out that customers would be less happy to lose: the FireWire port.

Can I shed some eye water here over the demise of FireWire—aka the IEEE 1394 interface? Introduced in 1995, it was touted as a panacea, speedily transferring information to and from gear like disc drives, other computers, and especially video cameras. Coming after the madness of the SCSI (“scuzzy”) system, with bulky sockets called terminators and cables so thick they could hold up bridges, FireWire was a godsend. It even won an Emmy.

Losing FireWire got me thinking about all the ports and standards that have vanished over the years, leaving behind a trail of memories and a dumpster’s worth of orphaned peripherals. Our pop-in wires now transmit megabytes in seconds, but there’s a buggy-whip-style frisson in recalling the feel of ridged plastic on your fingertips as you screwed in the socket of an RS-232
