CNET says the 15-year-old encryption technology used to secure voice communications on GSM cellular networks (like AT&T’s) will be cracked wide open in a few months. Skype, which encrypts voice communications using a variety of standards-based technologies, avoids this problem, at least for Skype-to-Skype calls.
So says a recent Stanford University study. Your brain is not engineered to do more than one conscious thing at once. The apparent efficiency of multitasking is an illusion. You are actually dividing your attention into tiny slices and adding to your workload the complex task of deciding which piece of incoming information to pay attention to, then refocusing your attention. Of heavy multitaskers, one professor said, “Everything distracts them.” Said another, “”We kept looking for what they’re better at, and we didn’t find it.”
Multitaskers are bad at the tasks they are doing, bad at remembering, and even bad at switching tasks, despite all the practice they get.
Just cut it out already. You are hooked on overstimulation and trying to rationalize it. Quit bragging about it and get some help.
Twenty of the busier underground Metro stations, including major transfer points Metro Center, L’Enfant Plaza and Gallery Place, will soon get improved wireless service from all the major carriers: AT&T, Sprint Nextel, T-Mobile and Verizon. Since 1993, Metro has given Verizon the exclusive right to subterranean cell service, so this will be a big improvement for all those iPhone users on Metro (some Sprint phones were allowed to roam on Verizon’s network, so Pre users may already be surfing the tunnels).
The enhanced service begins October 16, 2009. The remaining 27 underground stations should be wired up by 2012. Metro says phone, text and internet services will be available.
Service will be based in stations, so surfing the web on the train when traveling between stations is likely to be spotty.
Money made it happen, Metro says:
Verizon Wireless, Sprint Nextel, AT&T and T-Mobile will build, operate, maintain and own the new wireless network that is currently being installed. The firms also will build a second wireless network, which Metro will own, operate and maintain for Metro’s own public safety and operational communications. The second network will support future plans to launch The Metro Channel, which will provide riders with rail and bus service information, news and advertising via monitors in stations, trains and buses.
The wireless contract will generate a minimum of nearly $25 million during the initial 15-year term and an additional $27 million during the five, two-year renewal terms. Other FCC licensed and unlicensed carriers may gain access to the networks either through entering into agreements with Metro or the group of carriers, which would produce additional revenue for the transit agency.
A new company called Swebapps promises to make an iPhone app for your business for $250-$450, plus a monthly $25-$35 fee. You choose, Chinese-menu style, from numerous possible “buttons,” which essentially serve as bookmarks for content stored on Swebapps’ servers. More buttons cost more money. The idea seems to be to make a mini-website in the form of an iPhone app.
I guess clients might think it is cool that I have an iPhone app even though they could get the same info by surfing to my website. But my prediction is that almost all clients would use such an app exactly once. On the other hand, do I care? Once I make an impression as “the guy with the iPhone app — so cool!” does it matter whether the client actually uses the app? Then again, this thing looks awfully plain (bordering on ugly) so maybe I would become “the guy with the lame iPhone app.”
The price is fairly modest if you have an actual revenue-generating business, but the pain in the ass of coordinating yet another web presence may be the biggest cost.
