It was almost totally to blame. In later recollections the
president and CEO of the Santa Fe Railroad said he could see the
future of passenger trains when jet airline service came to the
Chicago-Oklahoma City route. Within a week passenger loadings on the
Texas Chief dropped so drastically that the train ceased to be
profitable.

Probably not a major factor in crowding. Southwest Airlines for
a long time wouldn't carry U.S. mail because the Postal Service's
contract are so demanding and rigid that they are not always
compatible with passenger needs and conveniencee. Much of the
overnight mail is now carried by FedEx air under contract. But a
grezt deal of mail is still carried by train, in containers or trailer
moving on fast inter- modal trains whose schedules are not a great
deal slower than passenger train wer in earlier years.
Much of the mail is now carried by truck.

I just meant that the _ability_ to carry the weight involved, with fair
efficiency and economy and using more or the less the same flight crew,
ground crew, and fuselage size, makes it both possible and desirable for
airlines to increase passenger numbers (or seat numbers) up to, if not
well beyond, the density at which passenger comfort begins to be
compromised.

Much of the heavy loading area is not confined to the
northern states. The central part of the country is more
subject to ice storms and freezing rain which adheres to
cables and wires. The dividing line brtween heavy loading
and less severe runs east and west across Oklahoma, for
example.

Vast Spy System Loots Computers in 103 Countries
By JOHN MARKOFF
March 29, 2009
TORONTO - A vast electronic spying operation has infiltrated
computers and has stolen documents from hundreds of government and
private offices around the world, including those of the Dalai Lama,
Canadian researchers have concluded.
In a report to be issued this weekend, the researchers said that the
system was being controlled from computers based almost exclusively
in China, but that they could not say conclusively that the Chinese
government was involved.
The researchers, who are based at the Munk Center for International
Studies at the University of Toronto, had been asked by the office of
the Dalai Lama, the exiled Tibetan leader whom China regularly
denounces, to examine its computers for signs of malicious software,
or malware.
Their sleuthing opened a window into a broader operation that, in
less than two years, has infiltrated at least 1,295 computers in 103
countries, including many belonging to embassies, foreign ministries
and other government offices, as well as the Dalai Lama's Tibetan
exile centers in India, Brussels, London and New York.
The researchers, who have a record of detecting computer espionage,
said they believed that in addition to the spying on the Dalai Lama,
the system, which they called GhostNet, was focused on the
governments of South Asian and Southeast Asian countries.
Intelligence analysts say many governments, including those of China,
Russia and the United States, and other parties use sophisticated
computer programs to covertly gather information.
The newly reported spying operation is by far the largest to come to
light in terms of countries affected.
This is also believed to be the first time researchers have been able
to expose the workings of a computer system used in an intrusion of
this magnitude.
Still going strong, the operation continues to invade and monitor
more than a dozen new computers a week, the researchers said in their
report, "Tracking 'GhostNet': Investigating a Cyber Espionage
Network." They said they had found no evidence that United States
government offices had been infiltrated, although a NATO computer was
monitored by the spies for half a day and computers of the Indian
Embassy in Washington were infiltrated.
The malware is remarkable both for its sweep - in computer jargon, it
has not been merely "phishing" for random consumers' information, but
"whaling" for particular important targets - and for its Big
Brother-style capacities. It can, for example, turn on the camera and
audio-recording functions of an infected computer, enabling monitors
to see and hear what goes on in a room. The investigators say they do
not know if this facet has been employed.

U.S. Police tap into Twitter to keep public informed
Quick blogging tool finds wide following
By Rachel Lebeaux, Globe Correspondent | March 29, 2009
"Rte. 128/I-95 N Northbound at Exit 22: Grove St, Medical emergency:
Lft tw lns clsd. Use cau."
"**TRAFFIC ALERT** Rt 495 SB at Ex 16 (KING STREET), MV crash, all
traffic being diverted off highway to King Street. Avoid Area."
The cryptic communiqués might resemble text messages from teenagers,
but they're actually bits of useful public information from local
police departments, distilled down to 140 characters or less and
disseminated immediately to residents on Twitter, a social networking
platform that was launched in 2006 but has recently seemed to catch
on with everyone from high school students to US senators across the
country.
Police departments in Franklin and Wellesley (Massachusetts) have been
leading the way by using Twitter to push out information on traffic
and other activities. And now the service is gaining popularity, or at
least scrutiny, at other area departments.
Boston's Police Department launched its Twitter account this month,
with the Fire Department expected to follow shortly.
Police in Wayland are thinking about it, and so is Newton's Police
Department, where Lieutenant Bruce Apotheker observed: "We'll take a
look at anything that can assist us in getting information out."
Twitter is a blogging tool that allows users to post short messages,
up to 140 characters, which are then blasted out to their "followers"
- individuals who sign up to receive their Twitter messages, or
"tweets."
Participants can send out tweets as often as they like, allowing them
to share information in real time.
This immediacy drew Wellesley and Franklin police into the fold in
2007, ahead of many departments nationwide.

Is Facebook Growing Up Too Fast?
By BRAD STONE
WHEN Facebook signed up its 100 millionth member last August, its
employees spread out in two parks in Palo Alto, Calif., for a huge
barbecue. Sometime this week, this five-year-old start-up, born in a
dorm room at Harvard, expects to register its 200 millionth user.
That staggering growth rate - doubling in size in just eight months -
suggests Facebook is rapidly becoming the Web's dominant social
ecosystem and an essential personal and business networking tool in
much of the wired world.
Yet Facebook executives say they aren't planning to observe their
latest milestone in any significant way. It is, perhaps, a poor time
to celebrate. The company that has given users new ways to connect
and speak truth to power now often finds itself as the target of that
formidable grass-roots firepower - most recently over controversial
changes it made to users' home pages.
As Facebook expands, it's also struggling to match the momentum of
hot new start-ups like Twitter, the micro-blogging service, while
managing the expectations of young, tech-savvy early adopters,
attracting mainstream moms and dads, and justifying its
hype-carbonated valuation.
By any measure, Facebook's growth is a great accomplishment. The crew
of Mark Zuckerberg, the company's 24-year-old co-founder and chief
executive, is signing up nearly a million new members a day, and now
more than 70 percent of the service's members live overseas, in
countries like Italy, the Czech Republic and Indonesia. Facebook's
ranks in those countries swelled last year after the company offered
its site in their languages.
All of this mojo puts Facebook on a par with other groundbreaking -
and wildly popular - Internet services like free e-mail, Google, the
online calling network Skype and e-commerce sites like eBay. But
Facebook promises to change how we communicate even more
fundamentally, in part by digitally mapping and linking peripatetic
people across space and time, allowing them to publicly share myriad
and often very personal elements of their lives.
Unlike search engines, which ably track prominent Internet presences,
Facebook reconnects regular folks with old friends and strengthens
their bonds with new pals - even if the glue is nothing more than
embarrassing old pictures or memories of their second-grade teacher.

"dominant social ecosystem"? "essential tool"?
Sounds a little exaggerated to me.
Ever since personal computers became affordable and easy to use we
heard all sorts of predictions for all sorts of things--that never
came about.
200 million users sounds impressive--2/3 of the US population--until I
read that that was world wide. World wide that is not an impressive
number.
Now maybe down the road in the future it will have as many users as
people have telephones or TV sets.
Until then, I wish these articles would hold back on the hyperbole.

Social downsizing
One firm's recent layoffs unfold on Twitter, with some people even
getting job offers
By Scott Kirsner, Globe Columnist | March 29, 2009
For several weeks earlier this month, employees at Burlington,
Massachusetts-based Mzinga Inc. sensed there was some bad news
brewing. The company, which sells social media software and services
to help businesses with marketing, customer communications, and
employee education, hadn't been able to raise a new round of
funding. Doors to executives' offices that always remained open were
suddenly shut, and a board meeting was set for March 10.
"Everything came to a standstill," says one former employee, who
requested anonymity so as not to violate the terms of his severance
package. "Everyone knew it was going to be something significant, but
we were just saying, 'What's going on?' "
The situation was pretty typical of the tense times that precede any
layoff: On March 19, about 40 employees - roughly 18 percent of the
workforce - were terminated as part of the company's second round of
cuts in 2009. But what was unusual about Mzinga's situation was how
widely it echoed throughout the universe of bloggers and Twitter
users, since so many of the company's employees and customers - and
the analysts who track its ups and downs - are part of the online
community that shares morsels of information and "status updates" on
a moment-by-moment basis. This was a layoff for our Twittery new
times.
The first public hint that something might be up at Mzinga appeared on
Twitter. On March 16, a Forrester Research analyst named Jeremiah
Owyang wrote to his Twitter audience that he'd been hearing that
"Mzinga is having financial difficulties. They need to brief me
immediately." Later that day, Mzinga's public relations manager
replied, again publicly on Twitter, that she'd set up a time for
Owyang to speak with executives.
Later that day, Owyang posted a short note on his blog, headlined
"Expect changes at Mzinga." Without explaining what was happening at
the company - he hadn't yet spoken to anyone there - he suggested
that Mzinga clients and prospects "stall any additional movement till
they brief me," which he expected to happen one week later. The
subtext of his post was that signing any new deals with Mzinga would
be unwise.

ABOUT NEW YORK
The Officer Who Posted Too Much on MySpace
By JIM DWYER
March 11, 2009
In pictures, Vaughan Ettienne is a champion bodybuilder of surreal
musculature. In conversation, he is polite and thoughtful.
And in the looking glass of his computer screen, he becomes a man of
fierce, profane views on how to keep law and order. A few weeks ago,
he posted a description of his mood on a MySpace account. "Devious,"
he wrote.
The next day, a man accused of carrying a loaded gun would go on
trial in State Supreme Court in Brooklyn - and in large part, the
case rested on the credibility of Vaughan Ettienne, bodybuilder,
Internet user and arresting officer.
What seemed like a simple gun possession case became an undeclared
war over reality: Was Officer Ettienne a diligent cop who found a gun
after chasing an ex-convict weaving through traffic on a stolen
motorcycle? Or was his story a "devious" facade in keeping with the
ruthless character he revealed on social network Web sites?
"You have your Internet persona, and you have what you actually do on
the street," Officer Ettienne said on Tuesday. "What you say on the
Internet is all bravado talk, like what you say in a locker room."
Except that trash talk in locker rooms almost never winds up
preserved on a digital server somewhere, available for subpoena. The
man on trial, Gary Waters, claimed that Officer Ettienne and his
partner stopped him, beat him and then planted a gun on him to
justify breaking three of his ribs.
Suddenly, Officer Ettienne was being held to the words that he wrote
in cyberspace.

I find the use of a _subpoena_ for private writings rather disturbing.
Given that attitude, can any criminal defendant subpoena a cop's
personal diary? Family and friends to see if he discussed the case
with any of them? Details about his private life? Indeed, a
defendant should be able to subpoena all sorts of things about anyone
connected to his case in any way.
This reminds me of schools going after kids who write stuff on their
own computers that are not connected in any way with the school. IMHO
they have no right to do that.
***** Moderator's Note *****
The writings weren't private. YouTube, Facebook, and other such sites
are, by design, public and available to all.
That said, the question becomes "Whose business is it"? The issue is
not what he said or wrote, but rather whether he is entitled to a
private life when not at work: in other words, if a police officer (or
other civil servant) is ever "off duty".
This isn't about computers or social networking sites: the medium is
being confused with the message. Had the officer said these things in
a "cop's bar", he would have been immune from subpoenas because cops
regard such places as safe havens where they may vent their
frustrations with fear of being called to account.
Sooner or later, our society will have to decide that we are not
entitled to demand that policemen be superhuman. So long as we expect
them to behave like cardboard-cutouts of Hollywood steriotypes, we
will continue to see periodic outbursts of repressed anger - remember
Rodney King? - as the all-too-human men who keep a lid on the American
melting pot act out their resentment at the simplistic and
hypocritical way they are judged.

And if a person accused of attacking a cop had made personal writings
about how he liked to attack cops, would you find their subpoena
disturbing?

In this case, the cop had apparently bragged about using illegal
techniques against defendants (he says it was just hot air, making
himself look tough). Frankly, the "private writings" are potential
evidence of commission of crimes by the cop, though of course the cop
may well turn out to be a blowhard rather than an actual criminal.

If being "superhuman" means, conducting themselves within the law, I
would hope not. If it means that society should ignore the matter
when a policeman brags that he has committed crimes, I would hope not.
If we have policemen who brag about activities that may be criminal, I
think as a society we have to pay close attention. Even if the brags
turn out to be lies.

Blowing off steam and pretending to be Rambo are hardly outside the
law, but you're entitled to your opinion.
I once had a confrontation with the father of a teenage girl who had
appeared at a social event in clothes somewhat more revealing than was
customary during my youth. Her father took exception to my wide-eyed
stare, and I responded "Here's a tip - one father to another, OK? -
worry about the guys who _don't_ look"!
In other words, an officer who vents in a public forum is, IMHO, far
less a danger than cops who pretend that the brutal work of policing
doesn't affect their outlook on life.

`Greater use of social network sites is making it harder to maintain

By analysing links between users of social sites, researchers were

The anonymised data is produced by social sites who sell it to

The results suggest web firms should do more to protect users'

If only US perveyors of long distance and cell phones even had 30
second billing in the US! Pretty much all cell phone carriers charge
in full minute increments and also charge as "send to end" meaning
they bill for calls even the connection and ringing time before the
end party answers. Carriers have the ability to charge as accurately
as they choose to, but do not choose to do so since it uses lots more
minutes with the combination of full minute increment billing combined
with send-to-end billing will assure the most possible revenue for all
calls. I dare say that if people were charged the actual usage in
minutes many people could conceivably sign up for plans with less
minutes allowed per month at a lower rate.
