I don't even see anyone using iPhones here in Silicon Valley -- it's all Android. Earlier this week I attended the first annual Plug Computer Developer Camp hosted by Marvell (http://www.marvell.com/) in Santa Clara CA. Ugh, talk about information overload. :-) There were a ton of sessions focused on interfacing between Plug computers and Android; nothing for iPhone. A computer I received for attending the Camp is a Globalscale (http://www.globalscaletechnologies.com/ Guruplug Server which is about the same size as my SheevaPlugs and it features both WiFi and Bluetooth. What is neat about its WiFi is that it can be quickly changed from an AP (Access Point) to a Client. Note also the Server-Plus has two gigabit Ethernet ports vs. the Server's one. An amazing thing about these Plug computers is low power operation; I measured mine (using a Kill-A-Watt) to vary from 4 to 5 watts. From the factory the SheevaPlugs come with Ubuntu and the GuruPlugs with Debian installed. These are all based on 1.2GHz to 2GHz ARM computers which are used in many cellphones. I don't (yet) have pictures of my GuruPlug Server but you can see one of my SheevaPlugs here (pictures from 2009): http://thadlabs.com/PIX/SheevaPlug_first.jpg http://thadlabs.com/PIX/SheevaPlug_labelled.jpg http://thadlabs.com/PIX/SheevaPlug_underside.jpg http://thadlabs.com/PIX/Sheevaplug_Webmin.jpg http://thadlabs.com/PIX/SheevaPlug_ext_HD.jpg More info about Plugs at the above URL for Globalscale and here: http://plugcomputer.org/, and http://computingplugs.com/index.php/Main_Page Another manufacturer of Plug computers is Ionics (who uses the Marvell Sheeva 2 GHz 88F6282 RISC ARMs): http://www.ionicsplug.com, and http://www.ionics-ems.com ***** Moderator's Note ***** Ah, but WHY does Google have the right answer? Is Android going to change the way consumers use cell phones? I doubt it. Will it change the functionality? No. So, where's the advantage? Compared to the cost of the phone, or the revenue cell carriers receive, the license fees for existing phone software are probably not enough of a factor to make Android a game-changer. My 2¢.

Subject: Why we love Ct. librarians, and admire Nicholas Merrill Message-ID: <Pine.NEB.firstname.lastname@example.org> Nicholas Merrill owned an ISP in NYC, was served with an FBI "National Security Letter" - along with an associated gag order. He fought it. Connecticut librarians received them, too, and with the gag orders as well. They fought back. Reporter Amy Goodman is co-host of a widely admired radio (and now tv) program, Democracy Now. Loosely affiliated with WBAI/Pacifica Radio in NYC and fed to affiliates around the world. She interviewed Mr. Merrill a week ago. Given that tens of thousands of NSLs have been served each year, many of which have been handed over to telecom and similar groups, the interview illustrates a disturbing practice. "We begin today's show with a guest here in New York who has been under an FBI gag order for the past six years. In early 2004, an FBI agent visited Nicholas Merrill and handed him a national security letter that ordered him to hand over detailed private records about some of his customers. At the time, Merrill was running an internet service provider in New York called Calyx.

All toll calls must be 11D. >(Local calls can be dialed with 10 or 11D.) I wasn't discussing dialing plans that included toll alerts. (My area has never had toll-alerting dialing plans.) I'm stating that a typical cell phone subscriber would request telephone number assignment from a particular area code without concern for rating point, a concept he won't even be aware of applying to inbound calls to cell phones. Depending on local calling plans available, a call to a cell phone in the home area code could very well include distance-rated charges because the rating point assigned to the cell phone could be a great distance from the caller's exchange, even though it's a home area code call. Local calls in my area, at various times, depending on the calling plan, some calls were time-and-distance rated as toll calls, on the state-wide long distance calling schedule, even though on other calling plans they could have been time-and-distance rated as measured service, a cheaper rating plan that never applied to (what would eventually be called) in-state interLATA calls. On still other plans, the same local call could be included in the pre-paid area. In the mid '80's, we went to another plan for local calls that changed everyone's rates in that calls within 8 miles (later 15 miles) were flat rate untimed and calls beyond were time-and-distance rated on something that had been similar to the measured rates for local calls, and only in-state inerLATA calls were rated on the state-wide toll schedule. When we got "competition" for "local toll", generally, calls within 15 miles were untimed or prepaid (there was a choice), and calls beyond were rated on the schedule of the carrier one selected. All Chicago area codes include points that are more than 15 miles in between so there's great potential for calls to home area code cell phones to have distance charges under all the scenarios I described. But a cell phone subscriber won't likely be aware of it and won't request a cell phone number assigned to a rating point that could avoid distance charges for some of his inbound callers, like family members. Well, not until he saw his next residential phone bill.

Depends where you are. Where I live, people are quite aware of the difference between an Ithaca and a Binghamton number. They're both 607 numbers, but different LATAs so for most landlines it's an expensive toll call from one to the other. FWIW, we do not have and have never had toll alerting, either. In New Jersey, people know Trenton vs. Atlantic City numbers for the same reason, again no toll alerting but inter-LATA toll. R's, John

It appears to be the same ETC technology, but it doesn't interoperate with EZPass and Fastlane. Their web site says they're working on it. >I've read where parking can be paid for by cellphone. Any toll >facilities thinking of allowing for that? Not that I've heard, but you can pay for airport parking at LGA, JFK, EWR, ALB, SYR, and ACY with your E-Zpass, as well as some parking lots in Atlantic City and parking for the NY State Fair in Syracuse next week. See you there. R's, John

Pogue got it wrong. It is the DNS, but it's not how the web works. He's probably thinking about what he could have learned from a textbook in the 19900s, when TCP/IP was still sort of fresh, and seemed to work the way it did in the early 1980s when it first went public. But it doesn't work like that any more. TCP/IP is obsolete, sensescent, and held together by a remarkable collection of bailing wire and spit. DNS is just one of the old wads of chewing gum. When I look up www.google.com here, I get 184.108.40.206, not the number he gets. This is to be expected. DNS and the web go together like SPAM (that's the Hormel stuff, not the lower-case email stuff) on a bagel. TCP/IP was designed when the ARPANET had a few hundred host computers, mainly timesharing systems, and each was connected to one of the government-owned IMPs (as its routers were called then). Since the early pre-TCP/IP (it used NCP for its first decade or so) ARPANET wanted to get going and prove packet switching before it thought about addressing, it simply copied the telephone network of the 1960s. The first part of the NCP address identified the IMP; the second part identified the port on the IMP. When TCP was developed around 1975 (IP was split off of it in 1978, in Version 4, hence it began as "IP version 4"), they simply copied NCP's semantics. Which were already wrong. An IP address thus does not identify a computer. It identifies a connection to a network from a computer. Two connections? Two addresses. Each router thus has multiple addresses, one on each port. Heck, even the phone network is well beyond this nowadays... And because it's identifying the underlying link, not the node, an IP address is not an "internet" address (layer 3); it is simply a synonym for a layer 2 (link) address! There is no true layer 3 address in TCP/IP. But now let's move on. Addresses pretend to identify host computers. But the web rarely has a one-on-one relationship between host and IP address. Take a small web site like mine, http://www.ionary.com/ . It's hosted at an ISP's server, and the IP address is shared among many web sites. You really think anyone's getting a dedicated computer and IP address out of a hosting plan that costs under $20/month? Of course not. HTML, however, is smarter than IP; it's one of the best-designed application protocols. It sends the actual URL to the server. So the server is responding to the URL, not to the IP address. The server may have a default service associated with its own address, but everybody else is only reachable via the URL. And that's the way it should be. Applications, like the web, should only be addressed at the application layer. Underlying plumbing, like IP, should be hidden. So that's the case where a lot of small web sites (URLs) share an IP address. What about Google? That's the opposite case: One web site needs many, many servers. This isn't what DNS was built for. What we have here, instead, is a case of *anycast*: Many devices all share the same identity, and any one of them can field the question. In the telephone world, this is akin to "multiple appearance directory number - single call appearance" (MADN-SCA), or a call distributor. Contrast this with multicast, which is MADN-multiple call appearance (one number rings multiple phones). Anycast is far more common, but gets less attention. How is anycast done with TCP/IP? On a small basis -- a few servers in one location -- it's typically done with a distributor like a "Big Iron" box. This is a specialized router that receives the HTTP request and forwards it to one of a group of servers. But what happens when one distibutor can't handle it? That's when you have to start hacking DNS, as Google does. In such a case, DNS does not return a single address to a request. It distributes the requests among multiple IP addresses. So the one cached in the DNS server my ISP is using might not be the one cached in the DNS server yours is using. And it may change. It can also be done more cleverly, looking at the IP address that's making the request, and returning the IP address of the distributor that's closest (in Internet terms, like hops, or being on the same ISP) to the requester. This is how content delivery networks (CDNs), like Akamai, work, too. They return the IP address of the nearest Akamai server. So it's really all about work-arounds. If you use a third-party DNS server like OpenDNS, as Pogue suggests, you get the IP address in the OpenDNS cache, or from the server that they are directed to (DNS is a hierarchy of referring servers). This may be the one closest to them, not you, and thus not even the ideal choice.
