Car batteries are inappropriate for this type of usage; their internal
plates are w-a-y too thin -- they're designed for starting a car quickly
then accepting a continuous recharge, period.
The correct types of batteries are marine deep discharge trolling
batteries and the similar kind for powered wheelchairs and golf carts.
These batteries have extremely thick lead plates and are also quite a
bit heavier by volume (typically 50+ pounds per battery).
One of my hobbies is astronomy and I know what works and what doesn't
to operate a computerized scope and accessories from dusk to dawn.
I get the 85aH (Amp/Hour) or greater capacity batteries at discount
stores like Costco and they're also available at marine suppliers; the
wheelchair batteries can be found at Sears and similar. I use battery
cases from sporting goods suppliers such as Cabelas because one doesn't
want these batteries "naked" and exposed -- they have enough current to
vaporize a screwdriver, for example. :-)
Some of my smaller scopes work fine with "jumpstart" batteries such as
these http://thadlabs.com/PIX/battery_packs.jpg [note the cases from
Cabelas on the right side] per http://thadlabs.com/PIX/LX200+DS80.jpg,
but the deep-cycle batteries are mandatory for prolonged use or high-
power use such as the SBIG STV device at the left in the LX200+DS80
photo.
Another advantage of "external" batteries for a UPS is the UPS won't
be ruined when the internal batteries go belly-up and leak; I've lost
numerous UPS systems (APC, Best, etc.) over the years that way (with
internal batteries only).
***** Moderator's Note *****
I don't think car batteries get a continuous recharge: IIRC, the
voltage regulator interrupts the circuit from the alternator to the
battery when the proper voltage is reached.
However, this brings up a good question: are car batteries suitable
for use in any backup service? Despite their shortcomings, their
price/performance ratio might justify the compromises.

Telling Friends Where You Are (or Not)
By JENNA WORTHAM
March 14, 2010
AUSTIN, Tex. - As Jordan Viator roams the conference rooms, dimly lit
bars and restaurants here at the South by Southwest Interactive
conference, she often pulls out her cellphone and uses the Foursquare
service to broadcast her location.
Such a service might sound creepy to the privacy-minded. But it came
in handy for Ms. Viator when she arrived Friday at a party in a bar
called Speakeasy and could not find anyone she knew. Her friends who
also use Foursquare could see where she was, and some joined her a
few minutes later.
"I only share my location with people I am comfortable meeting up
with, and when I want to be found," said Ms. Viator, a 26-year-old
communications manager at a nonprofit company.
Mobile services like Loopt and Google's Latitude have promoted the
notion of constantly beaming your location to a map that is visible
to a network of friends - an idea that is not for everybody.
But now there is a different approach, one that is being popularized
by Foursquare.
After firing up the Foursquare application on their phones, users see
a list of nearby bars, restaurants and other places, select their
location and "check in," sending an alert to friends using the
service.
This model, which may be more attractive than tracking because it
gives people more choice in revealing their locations, is gathering
speed in the Internet industry. Yelp, the popular site that compiles
reviews of restaurants and other businesses, recently added a
check-in feature to its cellphone application. And Facebook is
expected to take a similar approach when it introduces location
features to its 400 million users in coming months.
If checking in goes mainstream, it could give a lift to mobile
advertising, which is now just a tiny percentage of overall spending
on online ads. If a company was able to pitch offers to people who
say they are at a particular spot, it would "allow for the sharpening
of mobile advertising," said Anne Lapkin, an analyst at the research
firm Gartner.
The check-in idea got its start in 2004, when Foursquare's
predecessor, a service called Dodgeball, started to let people tell
their friends where they were with a text-message blast.
Most cellphones at the time did not have GPS location features, "so
using text to check in was a necessity," said Dennis Crowley, who
created the service with a classmate in the Interactive
Telecommunications Program at New York University.
In 2005, Mr. Crowley sold Dodgeball to Google, which eventually shut
it. He decided to expand on the idea with Foursquare.

How Privacy Vanishes Online
By STEVE LOHR
March 16, 2010
If a stranger came up to you on the street, would you give him your
name, Social Security number and e-mail address?
Probably not.
Yet people often dole out all kinds of personal information on the
Internet that allows such identifying data to be deduced. Services
like Facebook, Twitter and Flickr are oceans of personal minutiae -
birthday greetings sent and received, school and work gossip, photos
of family vacations, and movies watched.
Computer scientists and policy experts say that such seemingly
innocuous bits of self-revelation can increasingly be collected and
reassembled by computers to help create a picture of a person's
identity, sometimes down to the Social Security number.
"Technology has rendered the conventional definition of personally
identifiable information obsolete," said Maneesha Mithal, associate
director of the Federal Trade Commission's privacy division. "You can
find out who an individual is without it."
In a class project at the Massachusetts Institute of Technology that
received some attention last year, Carter Jernigan and Behram Mistree
analyzed more than 4,000 Facebook profiles of students, including
links to friends who said they were gay. The pair was able to
predict, with 78 percent accuracy, whether a profile belonged to a
gay male.
So far, this type of powerful data mining, which relies on
sophisticated statistical correlations, is mostly in the realm of
university researchers, not identity thieves and marketers.
But the F.T.C. is worried that rules to protect privacy have not kept
up with technology. The agency is convening on Wednesday the third of
three workshops on the issue.
Its concerns are hardly far-fetched. Last fall, Netflix awarded $1
million to a team of statisticians and computer scientists who won a
three-year contest to analyze the movie rental history of 500,000
subscribers and improve the predictive accuracy of Netflix's
recommendation software by at least 10 percent.
On Friday, Netflix said that it was shelving plans for a second
contest - bowing to privacy concerns raised by the F.T.C. and a
private litigant. In 2008, a pair of researchers at the University of
Texas showed that the customer data released for that first contest,
despite being stripped of names and other direct identifying
information, could often be "de-anonymized" by statistically
analyzing an individual's distinctive pattern of movie ratings and
recommendations.
In social networks, people can increase their defenses against
identification by adopting tight privacy controls on information in
personal profiles. Yet an individual's actions, researchers say, are
rarely enough to protect privacy in the interconnected world of the
Internet.
You may not disclose personal information, but your online friends
and colleagues may do it for you, referring to your school or
employer, gender, location and interests. Patterns of social
communication, researchers say, are revealing.

***** Moderator's Note *****
I've said before that the current generation of twenty-somethings is
the first in history to give up the last bastion of privacy: the names
of their friends. Social media, starting with Instant-messenger
programs and ranging up to applications that disclose a cellphone
user's lattitude and longitude, have allowed database designers to
compile social maps which will be eagerly sought after by marketers of
all kinds.
We're not yet at the point where our chopsticks have continuously-
scrolling advertisements on them, but I think that the "younger"
generation will soon realize that technology isn't always their
friend.

Subject: Power outages and batteries
Message-ID: <siegman-8403E3.08390818032010@sciid-srv02.med.tufts.edu>
As an extension to the thread on keeping communications hardware running
on battery power during power outages and other emergencies:
I have 10 kW of commercially installed photovoltaic panels on the roof
of my house [1]. But when the grid goes down, this system goes down
also, for reasons I think I understand [2].
Adding a full-bore battery setup to this installation to capture some or
all the multiple kW that could be generated and used or stored even when
the grid was out for multiple days, would clearly be a large and
unreasonably expensive installation.
Seems to me, however, with a minor addition to the DC-to-AC inverter
electronics one might be able to switch to a backup DC-to DC mode where
the panels just trickle-charged a small set of low-voltage backup
batteries of the kind used in lanterns, power tools, or electronics at
say a few hundred watts charging rate. If we had a multi-day outage, we
could at least charge up some of these batteries each day, and use some
that charge for minimal purposes each night.
I've not gotten around to exploring the possibility of such a capability
with the vendor who installed our system, and I'm aware of the existence
of much smaller solar-to-battery units available at retail. I'm just
wondering if anyone on this group has seen any mention of this kind of
backup DC-to-DC trickle-charging capability built into any larger
residential solar systems?
[1] If anyone is curious why this large a system on a single-family
residence, it's a large old empty-nester house with half its area
converted into three rental apartments, so more or less 4 households
under one roof; PG&E will nonetheless only allow one meter; domestic
rates are sharply tiered; the house layout is near optimal solar-wise;
and we got in early on an good installation plan. So, it's saving us
enough on my electric bills that it should pay for itself over a decade
or so
[2] My understanding is the inverters need the grid AC to drive the
inverter electronics and keep them synched and running properly.
***** Moderator's Note *****
The only solar installation I've seen in person was a "standalone"
design, with the arrays used to charge batteries that handle the house
load at night or during cloudy days. The family has a generator to use
when the batteries get too low, since they're too far from the pole
line to have any outside feed.
I assume that it's possible to have both a battery-backup system, and
to sell power back to the electric utility, although I now realize
I've never seen such a system described.
The funny thing about solar is that a very small increase in cell
efficiency would push it over the edge into "gotta have" status. I'll
bet many major corporations are working on it right now.

There's nothing to wonder about, this is exactly the case in major metro
areas. When I first tried to get DSL in the early 2000s, Ameritech tried to
turn it on for me, but it turned out they had absolutely no idea how I got
service, what state the wires were in, and what else was hooked up to them
(I was listed as 19,000 feet from my central office, we've since gathered
that this is database code for "damifino"). They eventually gave up, and I
didn't get DSL until 2 years later after SBC took over and from what I can
tell, trashed lots of the old plant and started over. This turned out to
be nice for me, because they set up a brand spanking new uverse vrad just
one street over a couple months ago and I have stupid fast internet now,
and crackle-free phone service for the first time ever. *

In some (not all) applications older infrastructure had heavier and
more rugged construction than later construction. Some reasons
include:
--Longer term outlook: Companies expected they'd be around for awhile
and that the infrastructure needs would be stable. Thus, they were
willing to invest for the long term. For example, central office
switches were expected to last decades and were built accordingly.
--Cheap capital: Capital was cheaper going way back, so companies
could raise money to pay for the heavy infrastructure. In the 1960s
and 1970s capital became quite expensive.
--Limited material options: Not so much for telephone equipment, but
way back they didn't know as much about long term durability and
strength of materials. In order to prevent failure they were
conservative and used heavy designs. This allowed a long service
life. As time went on, they realized they could get away with lighter
designs. They also discovered substitute materials later on that were
cheaper and functional, but not necessarily as long lasting.
--Business freedom: Going way back there was less or no government
regulation and companies had more freedom to do as they chose.
Originally telephone service was expensive; a nickel per neighborhood
call (dime for across a big city) meant the equivalent of $2 or $4
today. By the 1960s telephone companies were under great pressure to
hold rates down and from unions to raise wages so they sought cheaper
methods that weren't as durable. Some Bell companies felt this rate
pressure more than others, and I believe what became NYNEX was subject
to quite a bit of rate pressure, perhaps not enough to pay for proper
service in areas that were costly to serve. (Maintaining the massive
underground wire plant in NYC must be very expensive, especially they
must dodge subways and numerous other utilities.)

It seems to me that the distinction in LAN PHY technologies between
broadband and baseband stems from the time during which there were
competing technologies such as IBM PC-LAN (broadband, using CATV
frequencies and physical media, with a head-end concentrator and
translator terminating the cable) and baseband technologies like
arcnet, ethernet, IBM PC-LAN baseband, etc. which applied the
datastream directly to the medium (e.g. manchester, nrzi, etc)

Hi Bill,
In short U-verse is one of AT&T uses to sell DSL/TV services using
Fiber. The VRAD (Video Ready Access Device) equipment does the actual
termination of the fiber trunks. They are big bulky boxes that AT&T
puts above ground if at all possible. From them you can get DSL and
or Digital TV plus what ever else AT&T can talk you into paying for.
Here is a link for more info on the subject.
http://en.wikipedia.org/wiki/Video_ready_access_device
And here is a link showing a picture of one style of equipment cabinets they
are using in neighborhoods:
http://i88.photobucket.com/albums/k185/clevelanddiary/vrad1_mapledale.jpg
Seems many of them use lithium batteries that were catching fires or
just plain exploding with enough force to blow the cabinets 50 feet
from the base. I hear that a company that supplied many of the
batteries to AT&T went bankrupt leaving them with the task of finding
their own replacements for the defective batteries that had not
already self immolated.

It is my understanding that the standard inverters do indeed require a
running connection to the grid to allow them to remain in phase, and if
you are going to have a system that will still power your own property in
the event of grid failure it has to be able to firstly isolate the grid
connection and then make any appropriate phase adjustment when the grid
returns and it reconnects.
I believe these setups exist, but are probably a bit more pricey than the
standard inverter.

That is an excellent point - I painted myself into a semantic corner
with my somewhat dubious assertion. Ethernet over twisted pair does
indeed have more in common with true baseband signalling systems like
RS-232 and T1/DS1 than it does with modulated carrier systems. There
is also an error in my original post that I should correct: I said
that the symbol rate is lower that the content bitstream, I meant to
say higher. I may never be able to think of it as true baseband
because of the extra signal transitions in manchester encoded ethernet
that don't actually carry data. This could lead to more semantic hand-
wringing on my part, because the extra transitions don't actually
qualify as symbols precisely because they don't carry data.... (These
are the kind of things that keep me up at night.)

Measured DC current (12V) on my FIOS box is .48 Amp. It rises
to .57 A when off-hook. The backup battery is 7.2 AH, and the
installer told me it's supposed to give around 12 hours of
backup. Of course, that's assuming the battery is kept
reasonably current. Replacing it is a "user responsibility".

Simple. They aren't. This is yet another example of a useless piece of
legislation pushed through because the people demand they "do
something". I wonder how many in the state capitol even understood the
technology they were attempting to regulate?

That is great, with all the noise I have been making with AT&T here in
Riverside to get U-verse, I agreed to let them put it on a corner of my
lot, it is city right of way, but I had to agree to it. I already had
one explosion when an underground transformer that the city installed on
the side of my house in 1977; it went up in 1985 and we then found out
it had PCS's in it.
