Subject: Why the Verizon iPhone is already too late Message-ID: <p06240877c887cf130a2f@[]> Why the Verizon iPhone is already too late Apple should have gone to Verizon in 2009 - before Android took off By Wilson Rothman msnbc.com updated 8/10/2010 9:05:49 AM ET Verizon Wireless might get an iPhone this January? It's about time. Or is it too late? New reports show that Google's Android is eating the iPhone's lunch. And by clinging to AT&T exclusivity and staying clear of Verizon, Apple is effectively serving up that lunch on a shiny silver platter. For a decade, Apple played Ice Man in a calculated dogfight of product design and marketing. It rarely made a misstep, and its successes were legendary as a result. This year, Apple has not shown itself to be so level-headed. You could cite Antennagate or the missing white iPhone as evidence Apple is losing its cool, but these are mishaps, destined to follow previous iPhonapocalypses and Applegeddons into the void of the forgotten past. No, the biggest reason is that it miscalculated how much a prolonged exclusivity with AT&T would cost. The deal has been lucrative - God knows AT&T pays well for the privilege - but the downside has been that Apple has let a reasonable iPhone copy become the No. 1 selling smart phone platform in America. It let this happen, by simultaneously creating a burning desire for an app-driven touch-screen smart phone, and then denying it to two-thirds of the American populace. That might be an old rant, but the detrimental result of this decision - or rather, the detrimental result of sustaining the decision for so long - are only now becoming apparent. ... http://www.msnbc.msn.com/id/38635041/ns/technology_and_science-wireless/

There are three LATAs that cross the Illinois-Wisconsin state line due to how communities are wired up. Two are mostly Wisconsin with a finger into Illinois. The third is just North Antioch, Wisconsin, an unincorporated area wired to the switch in Antioch, Illinois. The state used LATA boundaries but called the in-state LATAs and Illinois portion of interstate LATAs "market service areas", assigned numbers unique to Illinois because we didn't want to use the national numbering scheme, and regulated away. Two separate numbering schemes is pointless but at least the boundaries are the same. For regulatory purposes, the New York public service commission had exactly the same authority regardless of a LATA's interstate nature.

Physically or electrically? The model 15 printers I had had separate keyboard and printer mechanics and electrical wiring. Though the stock Teletype wiring was very complex (allowing for polar relays and lots of other options), the machine came down to two wires to power the motor, two wires to drive the printer selector magnets, and two wires from contact closures on the keyboard. They COULD be wired for full duplex, relying on a remote echo, but were often wired in series for a local echo and half duplex operation. On punched tape, I used to maintain Alden fax machines that printed weather maps in an FAA flight service station. The people would do a weather observation, punch a tape, and put it in the reader. Later, the reader would be polled from central location, and the tape would be sucked through the reader. That's the only place I've seen polled tape reading, though it probably was used elsewhere.

It saves line time because as you say the operator can't keep up with the transmission for any long period of time. It saves operator time when the circuit is heavily loaded and a central controller polls the out stations for traffic to be sent. This allows the operator to prepare the message and put it into the reader and then go away and do other things. Then the other use of paper tape was for message relaying without having to re-keyboard the messages. > An absolute non-issue with any 5-level TeleType(r) machine I ever > encountered. They were physically not capable of full duplex operation. They were perfectly capable of full-duplex operation - there is no fixed connection between the keyboard and the typing unit. But probably just about never operated where the typing unit was not connected to get local copy during keyboarding. >>Even the newer Teletype 33/35 keyboards were not easy to use. Some of >>the numeric shift characters did not match standard typewriters and >>the keyboard was 'heavy'. The 32/33 keyboards were pretty awful, but then those were cheap machines. The 35 keyboard was not bad. There was an issue in the design of keyboards for ASCII. To make a mechanical keyboard there had to be a simple relationship between the bits of the characters and the characters on the key tops, so that the shift and control keys affected all the other keys in the same manner. A standard was issued which allowed two different keyboard arrangements. One was called "typewriter paired" and had the keys arranged as was typical for typewriters at the time. The other was called "bit paired" and met the requirement for mechanical keyboards. Use of the "typewriter paired" arrangement required some electronic translation between bit patterns the keys could easily generate and those of the ASCII code. Of course in the modern PC keyboard the keys generate arbitrary binary numers for each key and software translates those into ASCII or any other code desired.

Perhaps when the FCC > office moved out of San Francisco. A participant in nyc.transit had a comment on the above: "Well, that was MY office from 1967 to 1995! The FCC office and that of its predecessor agencies had been in those same quarters since 1912, and the paging system was OLD - it used pre-WW-II vacuum tubes that were no longer available in the early 1970s when the oscillator failed! Each staff member was identified with a single letter, usually related to their first or last name (mine was P). We didn't have to do much training for the receptionists - just a list of who has what letter - and there was a large board on the wall opposite the front desk with the code for each person and an indicator of whether that person was in the office, had not yet arrived or had left for the day, or was temporarily out of the office. The equipment was replaced with a more modern oscillator in the mid 70s. In 1980, the office was moved from the third floor of the San Francisco Customhouse to the fourth floor, incident to an upgrade of the building, and the "code line" was replaced by a conventional PA system. The building was designated as a National Historical Customhouse (built in 1906 right after the earthquake). I was the agency's representative to the Relocation and Upgrade Committee and I could have written a Master's thesis on what it takes to make upgrades and repairs to such a structure. In 1986 the office telephone system was upgraded to one that included a paging function and the outboard PA system was retired. We took this system with us when we moved to an industrial park in Hayward, CA (a suburb) in 1990, and when that office was moved to another location in 2000 (after I retired as the District Director) the new telephone system had an integrated paging function as well. Memories, memories...... and it's OK to repost this story to the group where the original posting came from."

While maintaining the speed and uniform spacing on 60/66 circuits by manual keying was indeed virtuallly impossible, most press operators could readily do that speed punching tape, and with no more latency than that required for the small loop of tape under the sensor bar (maybe 1 or 2 seconds, most 5-bell ("Bulletin") material was sent by breaking the tape and starting cold on a new strip of tape. A press operator could do this more quickly than direct keyboarding. Only the most extremely urgent mateiral was sent by direct keyboarding ("Flash"), 10 bells or more. This was an extremely rare occurrence. "Japan surrenders.," e.g. The wire stays idle after a flash, with a bulletin following with a normal text lead, usually within a few seconds, the bulletin often being dictated to the operator. Most press operators could get the tape well below the sensor bar and feeding continuously within a minute or less. Many operators could put the tape on the floor, so far ahead of the distributor that the tape hung down to the floor. Wes Leatherock wesrock@aol.com wleathus@yahoo.com ***** Moderator's Note ***** The "sensor bar" that Wes refers to was a mechanical arm which hung down beside the tape reader on a Moder 19 or similar machine: if the operator who was typing the original text onto the punched tape wasn't fast enough to keep up with the reader, then the tape would become taut and the sensor arm would rise, interrupting the reader's feed mechanism. I don't know how an operator could "get ahead" of the reader: the Model 19's keyboard was drivin by the same shaft as the printing mechanism, so I don't understand how it was possible to exceed the reader's speed.
