QR Codes storing addresses and URLs may appear in magazines, on signs, buses, business cards, or on just about any object that users might need information about. Users with a camera phone equipped with the correct reader application can scan the image of the QR Code to display text, contact information, connect to a wireless network, or open a web page in the phone's browser. This act of linking from physical world objects is known as a hardlink or physical world hyperlinks. Google's mobile Android operating system supports the use of QR codes by natively including the barcode scanner (ZXing) on some models and the browser supports URI redirection, which allows QR Codes to send metadata to existing applications on the device. ... http://en.wikipedia.org/wiki/File:Japan-qr-code-billboard.jpg A giant QR Code [on the side of a building] linking to a website, to be read with a mobile phone. I've even used it -- I was walking with friends in Menlo Park one night and happened to pass a store we were interested in which didn't have the hours posted [at least, not where we could find them!], but they did have a sign in the window with a QR Code on it. No problem: I pulled out my Android phone, tapped the icon for the "Barcode Scanner" app, pointed at the sign, and in just a few seconds was on the store's web page reading their hours. Their phone number was also there, so if I'd tapped on that text string the phone would have dialed it.[1] -Rob [1] Yes, the phone's browser will do this even if the number doesn't have an explicit HTML anchor tag (link) on the page! [Probably because AFAIK there isn't a URL "dial://" scheme, is there?]

It's now quite routine when browsing in a store to pick up some item, scan its barcode with your phone, and hit the "Comparison Shopping" or "Web Search" button in the app to see what others are charging for the item.

High volume low value transaction processing firms don't care about individual customers - doing so costs too much money. Customers are a statistical set and outliers are a cost to be avoided. Customer service is designed to satisfy the majority and resolve common problems (see how easily the supermarket gives you your money back if a product is faulty). The telco (at some point) makes/made a call about the degree of flexibility it wants to build into its transactional processes & systems. The more flexible the systems and processes are the more expensive they are to develop, operate and maintain. Increased flexibility means more sophisticated (=expensive) training for the front line operators and their supervisors, and more complex(=expensive) management controls and audit systems to minimise fraud and errors. More flexibility equals fewer lost customers, less flexibility means more lost customers. The equation becomes one of trading off, for each class of flexibility, the potential number of customers who will be retained by the capability vs the cost of implementing that capability. A telco that decides to go for the "high volume/low cost/low price operator" model will probably choose to lock down the flexibility its systems and processes afford to front line staff to keep the cost of the process (both development and operations) low. As a consequence they will expect to lose customers whose requirements fall outside the very narrow set that they wish to offer - they are assuming that their set meets the needs of a high proportion of the market who will be attracted by the resulting low price. A telco whose brand positioning has a higher service component will make a different call and your requirement may fall inside their set. For whatever reasons, your needs fell outside the set of things that your operator wanted (was even capable?) of providing - you therefore fell into the set of customer they were willing to see leave. Its not evil, or stupid, just a decision call for their business portfolio managers. You may feel they are making a bad decision, but in the end they will survive or fail on what the statistical mass does. -- Peter R Cook

The first-sale doctrine is an affirmative defense to copyright infringement that allows legitimate owners of copies of copyrighted works to resell those copies. That defense, the court said, is "unavailable to those who are only licensed to use their copies of copyrighted works."

Subject: Finding a Smartphone to Fit Your Needs, Under $100 Message-ID: <p062408c9c8b0abc05d12@[192.168.1.70]> Finding a Smartphone to Fit Your Needs, Under $100 By FARHAD MANJOO September 8, 2010 So you want to buy a smartphone? After enduring the taunting of your friends, you are at the end of the contract on your creaky three-year-old not-so-smartphone. The device doesn't do e-mail or the Web, and it can't find your position on a map. There is only one problem. Now that you have decided to step into 2007, the choices baffle you. The mobile phone industry has changed enormously since you last shopped. There are several new companies making devices, the phones have an alphabet soup of hardware options, and they run software that can do all kinds of amazing things. For some shoppers, though, the powers of modern smartphones may be overkill. Perhaps you would like to occasionally send e-mail or get access to the Web from your phone, but you don't really care about playing games or editing movies. For you, is there an entry-level smartphone, a phone that will let you do some of the fantastic things your pals keep bragging about, but that won't cost too much or require a college course in using it? For the last few weeks, I have been testing several phones from the four major carriers - AT&T, Verizon, Sprint and T-Mobile. Although there is no official definition for what makes a phone "smart," the industry does have a few generally recognized criteria. A smartphone is usually capable of getting access to your e-mail. It can display Web pages in a way that doesn't distort them too much, and it can connect to the Internet using a cellular data connection (known as 3G) or your home wireless system (Wi-Fi). I defined "entry level" as any smartphone that costs less than $100 when you sign up for a new contract. These parameters did, of course, exclude the kings of the smartphone market - Apple's iPhone 4, Droid 2 from Motorola and the HTC EVO 4G. But you will be surprised what you can get for not much money upfront. A few of the best phones that I looked at cost less than $50, and some were completely free with a new contract. But that is just the price of the phone. When you step into the world of smartphones, the real sticker shock comes on your monthly bill. Most carriers require you to sign up for a data plan when you buy a phone that provides access to the Internet. These can add $15 to $30 a month over what you are used to paying for your dumbphone. ... http://www.nytimes.com/2010/09/09/technology/personaltech/09basics.html

Subject: Apps as Tour Guides Through New York Museums, Step by Step Message-ID: <p062408cac8b0ac497d22@[192.168.1.70]> Apps as Tour Guides Through New York Museums, Step by Step By BOB TEDESCHI September 8, 2010 The next time you're about to visit a museum, do yourself a favor and drop in on your favorite app store first. Most institutions have not yet created a mobile app, but as a group, museums are headed in that direction. In the last few months, free apps were released by the Museum of Modern Art and the American Museum of Natural History, in New York; the Los Angeles Museum of the Holocaust; and the San Francisco Museum of Modern Art (which also has an Android app). I recently tested the newest museum apps for New York. While they take distinctly different approaches, they demonstrate the vast potential for technology to help people make the most of a museum visit. They can also point to a restroom in a hurry. ... http://www.nytimes.com/2010/09/09/technology/personaltech/09smart.html

It shouldn't be too difficult, right? Yet the options available from Apple, the company that makes the software and hardware for those devices, can either be very expensive or very slow. There are essentially two options from Apple. You could pay $100 for a yearly Mobile Me account, gaining access to an iDisk drive that lets you drag and drop files into a cloud-based hard drive. These can then be retrieved from other computers and mobile gadgets running Apple's iOS 4 software. The alternate and less expensive option involves plugging an old-fashioned U.S.B. cord into your mobile device and then going to get lunch as iTunes slowly syncs your files. Or you can use a free third-party application. Although a number of file-sharing services have existed for a while, a new free product called ZumoCast, which had its debut on Wednesday, takes the idea of self-sharing to a new level by offering the ability to create a personal file-sharing cloud. ... http://bits.blogs.nytimes.com/2010/09/08/zumocast-offers-a-personalized-cloud/

But it may also open a window to better communication. By Kate Tuttle, Globe Staff | September 11, 2010 If teens want to talk to each other, they text. And text. A Pew Research Center survey reported earlier this year that text messaging has eclipsed phone calls and e-mail as the primary way that teenagers communicate with one another. Adults, increasingly, are in on it, too, according to a new Pew survey, with 72 percent now sending and receiving texts, compared to just 65 percent last year. Parenting in the texting age raises a number of vexing questions: Should parents text their teens, whether to nudge them out of bed in the morning or check in on their homework progress in the evening? Can teenagers open up about things more easily via text than in face-to-face conversations? Can anyone over 40 really read those tiny letters without squinting (or reading glasses)? The answers, in my house anyway, are yes, yes, and not me. My 17-year-old daughter, Addie, and I text several times a day, on topics ranging from the logistical (Me: "Did you remember to pack your tennis racket?'' Addie: "Yes, and can we pleeeeaaasssee go to cvs after school? I need makeup!'') to the profound ("Me: I'm sorry I yelled at you.'' Addie: "Me too''). On the logistical stuff, we've got company. Bethany Allen, 39, a mother of three in Belmont, says she and her teens text each other "constantly,'' mostly to check in and report on - as she says - stuff like, "Oh, this happened at school, or I got this grade on a test.'' For Allen, texting is a way to keep in touch, a technology she appreciates. "I just feel like I'm always in the loop. Literally, we text more than we talk,'' she says. "If anything, it's brought us closer together.'' Dr. Laura Prager, a child psychiatrist at Massachusetts General Hospital and mother of two teenagers, texts with her kids. It's a method she adopted when her older child, a son now in college, went through a phase of not answering her phone calls. "But if I texted him,'' she says, "he answered me right away.'' For a teenager who's out and about, at school or sports practice, texting is infinitely preferable to fielding phone calls from mom, especially in front of peers, Prager points out. ... http://www.boston.com/lifestyle/family/articles/2010/09/11/texting_can_distance_teens_from_parents_but_it_can_also_lead_to_better_communication/

What made it really bad was there wee a bunch of fires burning and First Responders had major communications problems with their AT&T phones. My Sprint phone and router worked fine as did my company Verizon phone. From all the chatter I saw on the local web page, AT&T lost a lot of their customer base up there. It turned out to be a Hardware problem at a main cell site and the parts had to come from out of state, and the techs either had to come from Reno, Nv. or Sacramento to fix it. At the least AT&T should have told their customers what was going on, but from what was said the customer support; at least first level was overseas. When I have problems with Sprint or my DSL or wireline I make sure I make the calls during the day, that way I'll get a US tech support site, but at least with DSL I have a special number to call which gets me to a NOC center for employees a can locate the problem fast and right where it is located. -- The only good spammer is a dead one!!

Subject: Re: In the pursuit of new customers, wireless companies forget their existing ones Message-ID: <20100912180147.289065pspgysh008@webmail.uslec.net> For possible future reference for mobile subscribers who may wish to play hardball with their arrogant carriers, what's the least costly way to use number portability to "park" your mobile number elsewhere and come back as a "new" subscriber to take advantage of incentives denied to existing subscribers? In the face of arrogant mobile carrier policies towards existing loyal customers, the "take your ball and go home" strategy may be the only effective way to deal with these louts. Also, sometimes speaking directly with carriers' "retention" departments can yield positive results when nothing else works. -Ed ***** Moderator's Note ***** You could buy a per-minute phone from Virgin Mobile or similar provider, and use your current number there, and then ask your former carrier for "winback" deals. Be careful, though: they pay close attention to billing addresses and similar info, so you'll have to do it for _real_ to make it work. Bill Horne Moderator
