Microsoft to Offer Free Virus Protection Software for
Windows
By ScottGilbertsonNovember 19, 2008

Microsoft plans to offer Windows users a new antivirus
package designed to protect the OS from viruses, spyware,
rootkits and trojans. The new software is tentatively code-
named Morro, and will be available for free to Windows XP,
Vista and 7 users sometime in the second half of 2009.
The new software will reportedly use very minimal resources,
which means it should work well with older PCs. If fact,
Microsoft says Morro has been specially designed for older
PCs and low-spec machines popular in developing nations. In
addition to its minimal processor demands, Morro has been
developed to use very little bandwidth,making it ideal for those
without broadband connections.
Morro will replace Microsoft's current, paid service, Windows
Live OneCare, which has been available on a subscription
basis for $50 per year.
While a free, antivirus solution that ships withWindows would
be a boon for the average user, it could also mean trouble for
third-party software solutions. Given that a bundled solution
could raise antitrust concerns -and would no doubt see
competitors likeMcAfee and Grisoft reaching for the lawyers-
Microsoftwill be offeringMorro as a separate download.
Assuming Morro can deliver decent security it should be a
welcome free addition to Windows, but we don't suggest
throwing away your third-party software just yet. Antivirus
software suites will likely continue to hold an edge over Morro
by offering additional handy tools - like passwordmanagers,
identity theft protection and browser-based phishing
protection.
Still, if you've been runningWindowswith no antivirus software
at all,Morrowill no doubt be better than nothing, and it's hard to
arguewith free.

GadgetDesigners Push the Limits of Size, Safety
By Brian X. Chen, August 28, 2008

Just as small, fast-moving mammals replaced lumbering
dinosaurs, pocketable gadgets are evolving to fill niches that
larger, deskbound computers can't reach. But as they shrink,
these gadgets are faced with problems mammals face, too,
such as efficiently dissipating heat.

The recent example of Apple's first-generation iPod nanos
causing fires in Japan raises the question of whether
increasingly innovative product designs are impinging on
safety. The nano incident illustrates how risk can increase as
devices decrease in size, says Roger Kay, an analyst at
EndpointTechnologies.

"As [gadgets] get smaller, the tradeoffs become more difficult,
the balance becomes more critical and there's less room for
error," Kay said. "I'm not surprised it's happening to the nano
because that's the small one. You're asking it to do a lot in a
very, very small package and that's pushing the envelope.”

There's no question that industrial designers' jobs have
become much more difficult as the industry demands ever
more powerful and smaller gadgets. With paper-thin
subnotebooks, ultrasmall MP3 players, and pinkie finger-
sized Bluetooth headsets becoming increasingly popular, it's
questionable where exactly designers draw the line between
innovation and safety.

Subways: The New Urban Status Symbol
Business Week - December 5, 2007
by Jennifer Fishbein

It seems like everywhere you turn these days, a new
high-speed train is whisking more passengers across longer
distances faster than ever before. A [NOUN] to Paris from
London is quicker than flying; Japanese bullet trains traverse the
320 miles from Tokyo to Osaka in two and a half hours; and
magnetic levitating trains in Shanghai cut through the city at 268
miles per hour. But while high-speed trains may grab all the
glamour, the more mundane business of subway construction is
what's driving the biggest growth for transportation companies.
Indeed, the world is seeing an unprecedented boom in new
subways and expansion to existing systems. Thanks to surging
economic growth and urban populations, demand for subways is
soaring in China and India. Lots of other places around the
world also are building new lines, from Dubai to Santo Domingo,
capital of the Dominican Republic. And many European and
American cities ? including even such improbable locales as Los
Angeles and Phoenix ? have caught the transit bug.

Problem-Solving and Prestige

Some cities build out of necessity. Rising prosperity
prompted Dubai residents to buy so many cars that they realized
they could [ADVERB] longer drive these cars because they
were stuck in traffic. Others are keen on the environmental
benefits of metros, which produce far less pollution and
encourage drivers to leave cars at home. Some places, mainly
in the Middle East, are looking to diversify their oil-dependent
economies. And others, to be honest, are chasing an urban
status symbol. Building a metro won't turn any old town into
Paris or London, but it does tell the world that you've arrived.

"You have in some cases a prestige issue, which is more
the case in young cities in need of an image," says Jean-Noël
Debroise, vice-president for product and strategy at Alstom
(ALSO.PA), the French transport company that has built a
quarter of the world's metros.

Rennes is an example of the new trend. The city of about
212,000 people in northwestern France was looking to raise its profile when it installed a metro in 2002. It raised the bar by
opting for a driverless system made by Siemens ? just like the
shiny new No. 14 line in Paris ? protecting passengers from the
French penchant for transit strikes. Turin, Italy, did the same to
help win its bid for the 2006 Winter Olympics; its driverless
system opened just before the games. Even the Spanish island
of Mallorca inaugurated a short metro line in April in hopes of
luring even more tourists to its capital, Palma. Alas, it closed
indefinitely in September due to flooding, amid charges of
mismanagement.

A Boon for Transit Builders

The world's three largest metro manufacturers, Montrealbased
Bombardier (BBDB.TO), Alstom, and Munich-based
Siemens (SI) report high demand for mass transit, including
tramways and light-rail systems that run both under and
[PREPOSITION] ground. The global subway market was worth
9.3 billion dollars in 2005 and is projected to grow at a rate of
2.7% per year until 2015, according to a 2007 study by the
European Railway Industry Assn. Subway lines [TO BUILD] or
extended in 20 European cities and five Middle Eastern ones,
and dozens of towns are constructing light-rail systems, reports
the Brussels-based International Association of Public
Transport.

The size of a city determines its need for a metro system.
Cities of a few million people ? or those anticipating huge
population growth ? really can't do without a mass transit
system. But cities of one or two million inhabitants can choose
between a subway and a surface tramway, which costs far less
but also runs more slowly. [CONJUNCTION] funding is an issue,
cities usually will spring for a subway, says Debroise. "The
tramway has a very old image of the 19th century, with horses in
the streets," he says.
