It's actually worse than you imply. SIP itself is pretty bad. Why in heaven's name does a supposedly modern protocol make use of ASCII text strings for its messages, as if users were sitting at teletypes and had to give commands to the other side? Sure, it was a nice hack for debugging early protocols in the 1970s, but today such syntax is a sin. Worse, SIP was defined with PSTN compatibility as a "non-goal". But it's mostly used for PSTN-linked calls. So the standards are vague, and everybody's implementation is different, so compatibility is a big deal. And it never quite does what the PSTN requires, at least in the US. But the worst of all is that it uses IP. The whole TCP/IP stack is obsolete, a 1970s lab hack run astray. It caught on because Berkeley provided free code in 1982, not on its merits. I suggest people look at the Pouzin Society site http://www.pouzinsociety.org/ to see an alternative, RINA (Recursive InterNetwork Architecture), which takes four decades of learning into account. -- Fred Goldstein k1io fgoldstein "at" ionary.com ionary Consulting http://www.ionary.com/ +1 617 795 2701

Does this go beyond the scope of Gant, or not? Gant hardly made it impossible for police to conduct warrantless searches of vehicles and did not find that inventory searches were unconstitutional. The article doesn't say how long his driver's license had been expired for, but if it's three months or less, it's a fairly minor vehicle code violation in most states and it's unusual that they'd impound the vehicle. What if the passenger were properly licensed and not intoxicated? Would the vehicle impoundment have been unconstitutional if she drove it?

I have to admit that the only business value in my "Smartphone" is the e-mail linking to my Exchange server as I spend most of my time either at client sites or on the road to and from them. It also gives me a convenient alternative to send and receive test e-mails as an external system to the systems I administer. Without that function I'd happily go back to a "normal" phone that only has to be charged 1/4 of the times the more bulky "Smartphone" requires. The only other valuable function I have really used on my "Smartphone" is reading the news online while in the waiting room for medical appointments! The rest of the things it can do are basically time wasting toys, (which explains the appeal to a lot of people). -- Regards, David. David Clayton Melbourne, Victoria, Australia.

Subject: The iPhone 4S, HSPA+, and When HSPA+ is Real 4G Message-ID: <firstname.lastname@example.org> The iPhone 4S, HSPA+, and When HSPA+ is Real 4G by Brian Klug 10/9/2011 A while after the iPhone 4S announcement, I posted a piece on the iPhone 4S' cellular architecture and talked about the new inclusion of HSPA+ alongside CDMA2000 1x/EVDO and some specifications. Since then, there's been some ongoing confusion about whether the device supports HSPA+, whether it's "4G," and just what all that really means. It's funny because this issue came up with the HP Veer 4G on AT&T a while back, and with that particular device I did a similar explanatory article in the context of a This Just In post. I wager the somewhat limited cross shopping (and commercial success of the Veer) resulted in many iOS users missing that discussion, and it's cropping up again for the iPhone 4S. The confusion is really twofold. First is a misunderstanding about 3GPP releases and what features are optional or mandatory. Second is a misunderstanding about HSDPA, HSUPA, and modulation coding schemes. Let's break it down. ... http://www.anandtech.com/show/4943/the-iphone-4s-hspa-when-hspa-is-real-4g

Subject: Early Orders Test iPhone 4S Appeal Message-ID: <email@example.com> Early Orders Test iPhone 4S Appeal By GEOFFREY A. FOWLER And IAN SHERR OCTOBER 8, 2011 Apple Inc. on Friday faced its first test since the death of co-founder Steve Jobs as it began accepting pre-orders for its latest iPhone. Apple and wireless carriers in the U.S. and a half-dozen other countries began taking Internet and telephone orders for the iPhone 4S in the pre-dawn hours. AT&T Inc. said it had "more than 200,000 preorders in the first 12 hours alone" making the iPhone 4S "the most successful iPhone launch we've ever had." A Verizon Wireless spokesman said "our systems were humming very strongly since 3 a.m.," and that executives were "pleased with the sales and the ordering process." ... http://online.wsj.com/article/SB10001424052970203388804576615731788704032.html

Subject: The Steve Jobs I Knew Message-ID: <firstname.lastname@example.org> The Steve Jobs I Knew Walt Mossberg OCTOBER 5, 2011 That Steve Jobs was a genius, a giant influence on multiple industries and billions of lives, has been written many times since he retired as Apple's CEO in August. He was a historical figure on the scale of a Thomas Edison or a Henry Ford, and set the mold for many other corporate leaders in many other industries. He did what a CEO should: Hired and inspired great people; managed for the long term, not the quarter or the short-term stock price; made big bets and took big risks. He insisted on the highest product quality and on building things to delight and empower actual users, not intermediaries like corporate IT directors or wireless carriers. And he could sell. Man, he could sell. As he liked to say, he lived at the intersection of technology and liberal arts. But there was a more personal side of Steve Jobs, of course, and I was fortunate enough to see a bit of it, because I spent hours in conversation with him, over the 14 years he ran Apple. Since I am a product reviewer, and not a news reporter charged with covering the company's business, he felt a bit more comfortable talking to me about things he might not have said to most other journalists. Even in his death, I won't violate the privacy of those conversations. But here are a few stories that illustrate the man as I knew him ... http://allthingsd.com/20111005/the-steve-jobs-i-knew/

Subject: Book Business Sees a Bonanza in a Forthcoming Biography Message-ID: <firstname.lastname@example.org> Book Business Sees a Bonanza in a Forthcoming Biography By JULIE BOSMAN October 6, 2011 It took only hours on Wednesday night for Walter Isaacson's forthcoming biography of Steve Jobs to shoot up the best-seller list on Amazon.com, eventually moving from No. 384 to the No. 1 spot. On Thursday morning, a book buyer at Powell's Books in Portland, Ore., quintupled its order of the book, to 500 copies. Simon & Schuster, the publisher, said it was accelerating the publication, moving the release date to Oct. 24 from Nov. 21. And by the afternoon, the publishing industry was marveling at the potential of the book, simply titled "Steve Jobs," weeks before its release. ... http://www.nytimes.com/2011/10/07/business/media/book-business-has-big-hopes-for-biography-of-steve-jobs.html ***** Moderator's Note ***** Who said we don't honor our dead?

Subject: With Time Running Short, Jobs Managed His Farewells Message-ID: <email@example.com> With Time Running Short, Jobs Managed His Farewells By CHARLES DUHIGG October 6, 2011 Over the last few months, a steady stream of visitors to Palo Alto, Calif., called an old friend's home number and asked if he was well enough to entertain visitors, perhaps for the last time. In February, Steven P. Jobs had learned that, after years of fighting cancer, his time was becoming shorter. He quietly told a few acquaintances, and they, in turn, whispered to others. And so a pilgrimage began. The calls trickled in at first. Just a few, then dozens, and in recent weeks, a nearly endless stream of people who wanted a few moments to say goodbye, according to people close to Mr. Jobs. Most were intercepted by his wife, Laurene. She would apologetically explain that he was too tired to receive many visitors. In his final weeks, he became so weak that it was hard for him to walk up the stairs of his own home anymore, she confided to one caller. Some asked if they might try again tomorrow. Sorry, she replied. He had only so much energy for farewells. The man who valued his privacy almost as much as his ability to leave his mark on the world had decided whom he most needed to see before he left. Mr. Jobs spent his final weeks - as he had spent most of his life - in tight control of his choices. He invited a close friend, the physician Dean Ornish, a preventive health advocate, to join him for sushi at one of his favorite restaurants, Jin Sho in Palo Alto. He said goodbye to longtime colleagues including the venture capitalist John Doerr, the Apple board member Bill Campbell and the Disney chief executive Robert A. Iger. He offered Apple's executives advice on unveiling the iPhone 4S, which occurred on Tuesday. He spoke to his biographer, Walter Isaacson. He started a new drug regime, and told some friends that there was reason for hope. ... http://www.nytimes.com/2011/10/07/technology/with-time-running-short-steve-jobs-managed-his-farewells.html

(That's how come answering an inbound call, while roaming abroad, and instantly hanging up again cost me half what not answering it did.) But, yes, de-activate forward-to-voice-mail (easier said than done, BTW, at least with T-Mobile), and "the option of not answering the phone" is a viable one.
