The Terminator need not worry it will be replaced any time soon, but Cornell
University researchers have created a robot that can build copies of itself.
The robot is primitive and doesn’t do anything but self-replicate, but
the principle could be extended to a robot that could at least repair itself
while working in space or in hazardous environments, according to Hod Lipson,
Cornell assistant professor of mechanical and aerospace engineering, and computing
and information science. |
The robot is made up of modular cubes, or “molecubes,” each with
identical machinery and a replication program. They draw power through contacts
on the surface of the lab’s table. The cubes have electromagnets on their
faces that allow them to selectively attach to and detach from one another,
and a complete robot consists of several cubes linked together. Each cube is
divided in a way that allows a robot composed of many cubes to bend, reconfigure
and manipulate other cubes. For example, a tower of cubes can bend at a right
angle to pick up another cube. The robot cannot replicate unless the experimenters
supply it with additional modules.
Wanted: Twenty volunteer bloggers to hype anticipated operating
Microsoft is looking for bloggers to write about the beta release of Longhorn,
the upcoming version of its Windows operating system.
Team 99, as it will be known, will consist mostly of developers and enthusiasts
nominated by Microsoft community members. The blog’s purpose will be “to
tell…the truth about what Longhorn is all about,” as well as point
out any mistakes, according to the blog’s creator, Robert Scoble, a Microsoft
employee. Team members will get a look at pre-release copies of Longhorn before
its summer release, but they will have to sign non-disclosure agreements. The
full version of Longhorn is set to be released in late 2006.

In the June 1995 issue of ADT, David Linthicum, systems
manager at Mobile, argued in “Component Development: Easier Application-Building
Potential for Developers, Users,” for component-based development as an
alternative to object-oriented programming. He maintained that: “The
question is not whether component-based programming will take over application
development. In many respects it already has.” However, “it
will take time before the tools and rules are in place to support a standard
component infrastructure in which all applications can share components through
a common interface.”
Also weighing in on component-based development, Mark Hanner profiles two companies,
Next and Taligent, in “Frameworks Require Component Families.” He
lauds them for having “raised the bar in functionality by providing families
of sophisticated components, such as word processing and 3-D graphics,
that are integrated through common frameworks,” with their respective
products, OpenStep and TalAE.
Dilbert creator Scott Adams is profiled in “Tops in Trends.”
An engineer by day at Pacific Bell, Adams claims that much of the material for
the strip is based on his experiences at work. In fact, Adams says, “the
character Wally comes from a former co-worker who figured it was more profitable
to be the least productive employee and receive a buyout of his contract than
to continue working under the company’s incentive plan.”
It creeps and leaps and glides and slides—and can be seen in everything
from the Apple IMac to the New Beetle. It is The Blob, specifically blobitecture.
Application Development Trends regular contributor John K. Waters examines
this architectural style in blobitecture, Waveform architecture and digital
design (2003, Rockport Publishers). |
The book is a fascinating look at “womblike office cubicles,” potato
chip chairs and other blobjects and globjects, from their humble beginnings
in the 1940s as a rebellion against “Machine Age forms” to today’s
blobmeisters, with their powerful computers and advanced 3-D animation software.
Like its infamous B-movie cousin and with technological advances, blobitecture
is now quite literally “across the floor and right through the door.”
But luckily, we don’t have to beware of this blob.

Manufacturing is 50 percent more likely than other sector to cut IT spending
this year, according to a recent study by Info-Tech Research Group.
Twenty-one percent of manufacturing companies plan to decrease IT spending
this year, compared to an average of 14 percent for other industries, according
to Info-Tech’s Manufacturing Industry 2005 IT Budget & Staffing report.
The information is based on its January survey of more than 1,400 IT decision-makers
at mid-sized companies in the U.S., U.K. and Canada. Companies with fewer than
50 employees spend 20 times more per employee on IT than companies with more
than 500 employees.
Other findings include:
VoIP is the top investment priority for manufacturing companies, followed by
supply chain management and customer relationship management.
Storage is also an important investment priority, specifically in companies
with more than 500 employees.
Spending is varied among the different manufacturing segments. For example,
non-perishable and goods manufacturers spend five times more per employee on
IT than do steel and metal manufacturers.
Desktop hardware and software spending is flat; more than 60 percent of IT decision-makers
in manufacturing do not have plans to purchase new desktop software.
Three MIT pranksters have developed a program that generates computer-science
research papers that are grammatically correct, but made up of jargon and drivel,
so they make absolutely no sense.
Their Web site refers to it as “context-free grammar” and its purpose
is to “auto-generate submissions to conferences that you suspect might
have very low submission standards.”
Sure enough, a generated report, “Rooter: A Methodology for the Typical
Unification of Access Points and Redundancy,” was accepted by the World
Multi-Conference on Systemics, Cybernetics and Informatics 2005 as a non-reviewed
However, conference officials caught on to the ruse in time to disqualify the
paper. Go to http://pdos.csail.mit.edu/scigen/

Scientists and engineers at Los Alamos National Laboratory used a blog to express
their frustration with its director, Dr. George P. Nanos and his leadership
Several bloggers blasted Nanos’ decision to shut down the lab last July,
citing “egregious” safety and security violations when two classified
computer disks disappeared. However, there were no disks. The lab was closed
from July to February, costing taxpayers millions of dollars and the exodus
of talented staffers, according to the blog. The bloggers claim the shutdown
cost $850 million, although Los Alamos officials say it was $120 million, and
federal officials say it was $370 million.
The blog, which went live in January, has recorded more than 140,000 visits
and featured a petition for Nanos’ removal. Doug Roberts, a computer scientist
and a 20-year employee at Los Alamos, created the blog.
Australian scientists believe they have developed an unbreakable code that will
prevent hackers from stealing sensitive information.
Researchers at Melbourne University are growing diamond particles on optical
fibers to transmit information they say will be impossible to attack. The diamonds,
just 1/1000th of a millimeter, send information through a single photon, the
smallest known particle of light. Information, such as credit card data, is
usually sent via laser beams, which send billions of photons, making is easy
for hackers to steal them and crack the code.
The device sends a stream of single photons, and if communication is broken,
the information is corrupted, revealing the breach to the sender and the receiver.
The diamond particles are developed in a 1,500-watt microwave reactor, using
gases containing carbon to grow tiny diamonds over the tip of an optic fiber.
Researchers received a US$2.5 million innovation grant from the Victoria state
government to develop the prototype.
It’s sort of a high-tech version of Trump’s “The Apprentice”
TV show, except this one is a documentary that will focus on four interns hired
to develop software this summer at Fog Creek Software.
“Instead of wasting their talents giving them the usual dull and unimportant
tasks of a typical summer internship, we decided to let the interns create a
complete new software product, from beginning to end, over the course of one
summer,” says Joel Spolsky, founder of FCS, in his widely read Joel on
Software blog for developers (www.joelonsoftware.com).
“With experienced software developers as mentors, the team will design,
program, test and roll out a complete software product over the course of one
hectic summer, going from concept to paying customers in about 10 weeks,”
FCS hired the interns from Yale, Duke and Rose-Hulman. “We’re fairly
confident that three interns can get a beta version out in about 4 weeks,”
Spolsky says. “One chunk of the project is basically an enhancement to
the fogshop e-commerce engine; another chunk is a couple of simple features
added onto an existing open-source program; the third chunk is possibly the
simplest sockets-based server you can imagine that still does something useful.”
Each component is the equivalent of a challenging programming assignment at
Yale or MIT, Spolsky says. The fourth intern will focus on product marketing.
“We’ve been thinking of it as a kind-of serious Apprentice-meets-Real
World, Spolsky says. “Unlike The Apprentice, our business challenge will
be a serious 10-week project that becomes a real product, not four hours of
wrapping chocolate bars disguised as a business challenge.”
