Subject: Hooked on Gadgets, and Paying a Mental Price Message-ID: <p0624081fc8334d883e53@[10.0.1.3]> Hooked on Gadgets, and Paying a Mental Price By MATT RICHTEL The New York Times June 6, 2010 SAN FRANCISCO - When one of the most important e-mail messages of his life landed in his in-box a few years ago, Kord Campbell overlooked it. Not just for a day or two, but 12 days. He finally saw it while sifting through old messages: a big company wanted to buy his Internet start-up. "I stood up from my desk and said, 'Oh my God, oh my God, oh my God,' " Mr. Campbell said. "It's kind of hard to miss an e-mail like that, but I did." The message had slipped by him amid an electronic flood: two computer screens alive with e-mail, instant messages, online chats, a Web browser and the computer code he was writing. (View an interactive panorama of Mr. Campbell's workstation.) While he managed to salvage the $1.3 million deal after apologizing to his suitor, Mr. Campbell continues to struggle with the effects of the deluge of data. Even after he unplugs, he craves the stimulation he gets from his electronic gadgets. He forgets things like dinner plans, and he has trouble focusing on his family. His wife, Brenda, complains, "It seems like he can no longer be fully in the moment." This is your brain on computers. Scientists say juggling e-mail, phone calls and other incoming information can change how people think and behave. They say our ability to focus is being undermined by bursts of information. These play to a primitive impulse to respond to immediate opportunities and threats. The stimulation provokes excitement - a dopamine squirt - that researchers say can be addictive. In its absence, people feel bored. The resulting distractions can have deadly consequences, as when cellphone-wielding drivers and train engineers cause wrecks. And for millions of people like Mr. Campbell, these urges can inflict nicks and cuts on creativity and deep thought, interrupting work and family life. While many people say multitasking makes them more productive, research shows otherwise. Heavy multitaskers actually have more trouble focusing and shutting out irrelevant information, scientists say, and they experience more stress. And scientists are discovering that even after the multitasking ends, fractured thinking and lack of focus persist. In other words, this is also your brain off computers. ... http://www.nytimes.com/2010/06/07/technology/07brain.html?pagewanted=print ***** Moderator's Note ***** This is your Moderator - on a slow day.

Subject: An Ugly Toll of Technology: Impatience and Forgetfulness Message-ID: <p06240820c8334e266383@[10.0.1.3]> An Ugly Toll of Technology: Impatience and Forgetfulness By TARA PARKER-POPE The New York Times June 6, 2010 Are your Facebook friends more interesting than those you have in real life? Has high-speed Internet made you impatient with slow-speed children? Do you sometimes think about reaching for the fast-forward button, only to realize that life does not come with a remote control? If you answered yes to any of those questions, exposure to technology may be slowly reshaping your personality. Some experts believe excessive use of the Internet, cellphones and other technologies can cause us to become more impatient, impulsive, forgetful and even more narcissistic. "More and more, life is resembling the chat room," says Dr. Elias Aboujaoude, director of the Impulse Control Disorders Clinic at Stanford. "We're paying a price in terms of our cognitive life because of this virtual lifestyle." We do spend a lot of time with our devices, and some studies have suggested that excessive dependence on cellphones and the Internet is akin to an addiction. Web sites like NetAddiction.com offer self-assessment tests to determine if technology has become a drug. Among the questions used to identify those at risk: Do you neglect housework to spend more time online? Are you frequently checking your e-mail? Do you often lose sleep because you log in late at night? If you answered "often" or "always," technology may be taking a toll on you. In a study to be published in the journal Cyberpsychology, Behavior and Social Networking, researchers from the University of Melbourne in Australia subjected 173 college students to tests measuring risk for problematic Internet and gambling behaviors. About 5 percent of the students showed signs of gambling problems, but 10 percent of the students posted scores high enough to put them in the at-risk category for Internet "addiction." Technology use was clearly interfering with the students' daily lives, but it may be going too far to call it an addiction, says Nicki Dowling, a clinical psychologist who led the study. Ms. Dowling prefers to call it "Internet dependence." ... http://www.nytimes.com/2010/06/07/technology/07brainside.html?pagewanted=print

It was used to force modems to terminate a call on lines that would not drop loop current properly at a call termination. Symptom is just what you describe, the modem ends a connection but the phone line is not released for use by others. The modem is not detecting the loop current drop when the modem call ends and so stays "off hook" regardless of what the other end does. The actual command eludes my memory but it would force the modem to release the line regardless of the loop current condition at call termination. I remember not all modems supported the "extended" command but those that did it would stop (and mask) the problem. Hopefully someone here will have the actual command sequence at hand for you but I seem to remember it may have been an S register True it does not fix the possible phone line condition causing the problem but it will force the modem to stop being a part of it.

It helped that I was working for them at the time and had free access to use them on the BBS provided I would give them feedback on how they worked at my place. Now on with the show... I can think of one test that would help eliminate or identify an internal house wiring problem, if your line has a modern telephone demark. The kind with the little rj11 jack you remove and can plug in a telephone to get a direct connection to the phone line. What I would do is wire a rj11 jack into one of those surface mount phone jacks, the kind that accept two male rj11's. Wire both female jacks in parallel so that the common male rj11 can be used for both connections. Yes, just your basic phone line splitter. A store bought splitter can be used provided it is able to be plugged into the telephone line interface box provided it is not one of those Line 1 and Line 2 kind that look for two actual phone lines (numbers using the same common rj11. Then plug a phone into one side and your modem into the other (you may need a long rj11 to rj11 phone cable) and plug the male rj11 of the splitter directly into the phone interface. Try using the modem to call the internet and then terminate the call and then see if the phone on the splitter can draw a dial tone. If the problem goes away while using this rig you most likely have an internal wiring problem. If the problem persists then it's either your modem/phone still causing the problem or most likely a phone line problem for telco to fix. Last remove the setup and test again with your normal house phone jacks to verify the problem is still there. Would not be the first time just reseating a jack or moving wires has "cleared" the problem.

Subject: Thrifty Wi-Fi That Travels With You Message-ID: <p06240829c8335e9b3f4f@[10.0.1.3]> Thrifty Wi-Fi That Travels With You By THOMAS J. FITZGERALD The New York Times June 2, 2010 Wi-Fi is everywhere. Or so it seems until you really need it and there is no coffee house with a free hot spot. Or when you don't want to pay a fee to connect at the airport or a hotel for an hour. Our pockets and bags are filling with Web-connected devices: laptops, smartphones, netbooks, tablets, e-readers and even cameras. But to connect one when Wi-Fi is not available means using a cellphone network, and that usually requires buying a new data plan for each device. The cost-cutting solution might be to create your own Wi-Fi hot spot, a cloud of Internet connectivity for wherever you go. Not only can a personal hot spot provide a single point of access for all of your devices, it can be shared with friends. The options are growing. You can buy a simple, slim unit that fits in a pocket or ones that can shift from 3G to speedier 4G networks. You can convert some cellphones into hot spots, while a few new phones now come with hot spots included. I tried several such options while traveling and in my daily routine to see what they offered. The Novatel MiFi 2200, available from Verizon Wireless ($29.99 with a two-year contract) or Sprint (free after $50 rebate and with a two-year contract), is a Wi-Fi hot spot small enough to slip into a shirt pocket. It is a mysterious-looking object with no screen and a single button. It wirelessly connects to a 3G cellular network just like a phone, but it also broadcasts a Wi-Fi signal to the surrounding area. Devices within a 30-foot range can connect. I used the MiFi while traveling by car from Boston to New York. Having the coverage brought peace of mind when using Google Maps on my iPod Touch and my laptop to guide me around Brooklyn. Still, 3G speeds can be slower than what is available at land-based hot spots. Back at home, downloading my daughter's favorite videos was faster on our home wireless network. ... http://www.nytimes.com/2010/06/03/technology/personaltech/03basics.html

Subject: App Makers Worry as Data Plans Are Capped Message-ID: <p0624082bc83360c9c238@[10.0.1.3]> App Makers Worry as Data Plans Are Capped By CLAIRE CAIN MILLER and BRAD STONE The New York Times June 6, 2010 For the last two years, unlimited data plans have given app-hungry smartphone users an all-you-can-eat buffet. But will customers react to AT&T's new, limited menu by simply eating less? Some software developers fear they will, and if that happens, the caps on data use that AT&T has imposed could also make consumers lose their appetite for the latest innovations. Some developers worry that customers will be reluctant to download and use the most bandwidth-intensive apps and that developers will cut back on innovative new features that would push customers over the new limits. "What created this lively app world we are in was the iPhone on one hand, and unlimited data plans on the other," said Noam Bardin, chief executive of Waze, which offers turn-by-turn driving directions. "If people start thinking about how big a file is, or how fast an application is refreshing, that will be a huge inhibitor." New features on phones encourage more data use and vice versa. The next version of the iPhone, set to debut on Monday at Apple's Worldwide Developers Conference in San Francisco, will include a second, front-facing video camera, according to leaked reports. That could conceivably allow developers like Skype to offer face-to-face video calls from phones - a service that is much more data-intensive. AT&T, the second-largest carrier in the United States after Verizon Wireless, will move to tiered pricing on Monday and will no longer offer new smartphone buyers a simple $30 plan for unlimited data use. Customers will have to estimate how much data they are likely to use on their phone, buy an appropriate plan and then make sure not to exceed their limits. AT&T and some developers say that the new data plans could have the opposite effect and increase data usage by making it more affordable for most people. ... http://www.nytimes.com/2010/06/07/technology/07data.html

Subject: Prisoner of iTunes - the iPad file transfer horror Message-ID: <p0624083dc833dd0f66f5@[10.0.1.3]> Prisoner of iTunes - the iPad file transfer horror The conflict between consumption and productivity By John Lettice The Register 7 June 2010 First the good news - it's light, compact, reasonably capable for typing, and it has enough battery life for you not to be forever worrying about where your next power socket's coming from. These advantages alone are sufficient for me to take the iPad seriously for note-taking and for document viewing and manipulation, and to stop using the MacBook Air as the thing I carry around all the time. You can check out, but you can't leave But the bad news is that - in this iteration at least - the iPad is a conflicted machine. It's a media consumption device, and if it's just that it's an expensive one. Not that Steve Jobs is likely to go broke by selling expensive toys, as the sales figures remind us. But alongside this it has a capability as a productivity tool, and it's here that the problems start to tumble out. That doesn't mean it doesn't have a value there, but it does mean that it has considerable potential to become an infuriating device to use. So let's look at the infuriation: exchanging files, the iTunes tether, and the iPad's status as a big iPhone that can't make phone calls. These are all related. Apple won't let you anywhere near the iPad file system, and each app on the iPad has its own storage space. So if you've been using a file with one app, there's no way you can use it with another app without exporting it and then importing it into the other app. And how do you import and export? ... http://www.theregister.co.uk/2010/06/07/ipad_file_transfer/

What say the telcom oracles? The modem is not going off-hook and is pulling down the line so the line appears off-hook. If this is a quality modem, it will have MOVs and protection diodes on the incoming line. Check them to find out which one is shorted or leaky. --scott -- "C'est un Nagra.

I imagine the schematic is from a Bell System Pratice (BSP) used by all Bell System Companies and also followed by many non-Bell companies. The vacuum tube or diode was only used on phones on four-party lines to provide full selective ringing. It served no pupose on two-party lines and, as an extra cost to the company, was not provided on phones on two-party lines, or for that matter, for phones on four-party lines in offices which used divided code rining.
