A computer virus is alive and well on the International Space Station (ISS).

Nasa has confirmed that laptops carried to the ISS in July were infected with a virus known as Gammima.AG.

The worm was first detected on earth in August 2007 and lurks on infected machines waiting to steal login names for popular online games.

Nasa said it was not the first time computer viruses had travelled into space and it was investigating how the machines were infected.

Orbital outbreak

Space news website SpaceRef broke the story about the virus on the laptops that astronauts took to the ISS.

Nasa told SpaceRef that no command or control systems of the ISS were at risk from the malicious program.

The laptops infected with the virus were used to run nutritional programs and let the astronauts periodically send e-mail back to Earth.

The laptops carried by astronauts reportedly do not have any anti-virus software on them to prevent infection.

There's a global computing effort dedicated to moving vast volumes of data around the world. You already knew that, but this one isn't being used to pirate movies. It's the computational support system for the work that will take place at the Large Hadron Collider, and it's the largest scientific computing project to date.

Today, the European Organization for Nuclear Research (CERN) has announced that the LHC will go online on September 10.

But the only data CERN's Large Hadron Collider (LHC) has produced thus far is a thoroughly debunked urban myth—that the particle accelerator buried under the Swiss-French border will create an apocalyptic black hole.

Will the efforts of the world find the Higgs boson, or will scientists who should know better succumb to the temptation of hosting the largest game of Counter Strike ever seen? We'll have to wait and see.

Fix found for net security flaw

clipper's remarks: I read about the problem this morning and the fix tonight. Just that the first announcement was delayed till the fix was found and a bit of dramatics. Well done though.

Clip Source: news.bbc.co.uk

Computer experts have released software to tackle a security glitch in the internet's addressing system.

The flaw, discovered by accident, would allow criminals to redirect users to fake webpages, even if they typed the correct address into a browser.

Internet giants such as Microsoft are now distributing the security patch.

Security expert Dan Kaminsky said that the case was unprecedented, but added: "People should be concerned but they should not be panicking."

"We have bought you as much time as possible to test and apply the patch," he said. "Something of this scale has not happened before."

Mr Kaminsky discovered the error in the workings of the Domain Name System (DNS) about six months ago.

DNS is used to convert web addresses written in words - such as www.bbc.com - into the numerical sequences used by computers to route internet traffic around the world.

The flaw revolves around the way that the servers that translate words into numbers handle the requests they get.

A blind person goes to a library computer and uses WebAnywhere to read e-mail and consult an online bus schedule.

ScienceDaily (June 27, 2008) — Visions of future technology don't involve being chained to a desktop machine. People move from home computers to work computers to mobile devices; public kiosks pop up in libraries, schools and hotels; and people increasingly store everything from e-mail to spreadsheets on the Web.

But for the roughly 10 million people in the United States who are blind or visually impaired, using a computer has, so far, required special screen-reading software typically installed only on their own machines.

New software, called WebAnywhere, launched today lets blind and visually impaired people surf the Web on the go. The tool developed at the University of Washington turns screen-reading into an Internet service that reads aloud Web text on any computer with speakers or headphone connections.

ScienceDaily (June 20, 2008) — One litre of fuel would serve the UK for a year and oil reserves would last the expected lifetime of the solar system - if efficiency in the car industry had improved at the same rate as in the computer world - a leading computer scientist will tell an audience in Manchester, UK on Friday 20 June 2008.

Professor Steve Furber CBE, ICL Professor of Computer Engineering at The University of Manchester, will deliver the inaugural Kilburn Lecture to mark Digital 60 Day -- the 60th anniversary of The Baby computer, designed and built at The University of Manchester in 1948.

In his lecture entitled 'The Relentless March of the Microchip', Professor Furber will note that computers are now 50 BILLION times more energy-efficient than the 'Baby', which weighed roughly one tonne and took up a whole room.

TOKYO (AP)-- A California-based computer scientist, a philosophy professor and a molecular biologist will each receive US$460,000 after being selected Friday as winners of this year's Kyoto Prizes for achievement in the arts and sciences.

Computer scientist Richard Karp, a professor at the University of California, Berkeley, won the prize in advanced technology for his work in measuring how difficult certain computational problems are to solve -- a fundamental step in designing computer algorithms.

The award in arts and philosophy will go to Canadian professor Charles Taylor for developing a social philosophy that allows individuals from diverse backgrounds to keep their identities and still live peacefully together.

Currently, BlueGene/L is the most powerful computer in the world

A supercomputer built with components designed for the Sony PlayStation 3 has set a new computing milestone.

The IBM machine, codenamed Roadrunner, has been shown to run at "petaflop speeds", the equivalent of one thousand trillion calculations per second.

The benchmark means the computer is twice as nimble as the current world's fastest machine, also built by IBM.

It will be installed at a US government laboratory later this year where it will monitor the US nuclear stockpile.

It will also be used for research into astronomy, genomics and climate change.

"We are getting closer to simulating the real world," Bijan Davari, vice president of next generation computing systems at IBM, told BBC News.

It would be of particular use for calculating risk in financial markets, he said.

"The latency of the calculations is so small that for all practical purposes it is real time."

A New Way To Protect Computer Networks From Internet Worms

clipper's remarks: A good discovery, if we plebs can afford the spin off.

Clip Source: www.sciencedaily.com

ScienceDaily (Jun. 5, 2008) — Scientists may have found a new way to combat the most dangerous form of computer virus. The method automatically detects within minutes when an Internet worm has infected a computer network.

Network administrators can then isolate infected machines and hold them in quarantine for repairs.

They discovered how to contain the most virulent kind of worm: the kind that scans the Internet randomly, looking for vulnerable hosts to infect.

The key, they found, is for software to monitor the number of scans that machines on a network send out. When a machine starts sending out too many scans -- a sign that it has been infected -- administrators should take it off line and check it for viruses.

clipper's remarks: That's a lot of malware cleaners to sell. They are at freebie sites

Clip Source: www.theage.com.au

An OECD study into online crime says that increased activity by cyber criminals has left an estimated one-in-four US computers infected with malware.

The report, entitled Malicious Software (malware): a Security Threat to the Internet Economy, gives an impression of two worlds engaged in an uneven war of virus invasion and belated defence.

Cyber crime, to steal data, spy and attack government and business computer systems "is a potentially serious threat to the internet economy," the study, published on Friday, warns.

Organisations involved in "fighting malware offer essentially a fragmented local response to a global threat," the Organisation for Economic Cooperation and Development says.

"Over the last 20 years, malware has evolved from occasional 'exploits' to a global multi-million-dollar criminal industry ... Cyber criminals are becoming wealthier and therefore have more financial power to create larger engines of destruction."

Internet serves up 30 years of spam

clipper's remarks: 100 billion spam messages are sent everyday, Is that all, you say?

Clip Source: www.abc.net.au

Today marks the 30th anniversary of the computer phenomenon - spam email.

Now a nuisance for tens of millions of computer users worldwide, three decades ago someone sent what is considered to be the very first spam email.

Now 100 billion spam messages are sent everyday - three quarters of all the messages sent.

They are expensive to block and can slow down or crash computers across continents.

Spam reputedly got its name from a skit by the British television comedy show Monty Python's Flying Circus, in which a group of Vikings in a restaurant that serves all of its food with spam tinned meat, sing a song repeating the word ad nauseam.

Virus art ... clockwise from left, an artist's depiction of a phishing attack, sex dating spam, encoded trojan attack and email worm.

Cyber threats like NetSky, Mydoom and Parite are the bane of IT departments around the globe, but artist Alex Dragulescu has found subtle beauty deep within the dangerous computer code that can bring down networks and bombard email inboxes with murderous spam.

Dragulescu has peeled back the code behind the world's worst tech bugs and rendered stunning images from it. The Romanian-born MIT researcher and artist was commissioned to do the artwork by MessageLabs, a computer security company that sought to put a face - or at least a shape - on computer viruses.

Dragulescu found interesting, recurring patterns. He used the data to coax pointy green tentacles from the dreaded 'Mydoom' email worm and grew pretty peach petals from the epicenter of the 'Degreediploma5' spam file.

"Hello, Dave." Like a casting call for "2001 A Sapce Odyssey," the American Institute for Advanced Architectures (IAA) has designed the worlds first exaflop computer -a machine that would give HAL extreme paranoia. Unless you work for NASA or Dr Scorpio, exa- isn't a prefix you'll have seen much: it means a billion billion. A quintillion. Eighteen zeroes. Frickin' loads.

An exaflop computer could perform a thousand million billion FLoatin point Operations Per Second (FLOPS), made even more impressive by the fact our most advanced computers currently can't do one percent of that.

Who owns the Internet?

clipper's remarks: If you need to check on "basics overlooked at the time". this may help.

Clip Source: computer.howstuffworks.com

Imagine you're in a room full of people from different countries, and everyone only speaks his or her native language. In order to communicate, you'd have to come up with a standard set of rules and vocabulary. That's what makes the Internet so remarkable: It's a system that lets different computer networks communicate with each other using a standardized set of rules. Without rules, these computer networks wouldn't be able to communicate with each other.

Think for a minute about the scope of the Internet. It's a collection of inter-networked computer systems that spans the entire globe. It depends on several sets of rules called protocols. These protocols make it possible for computer communication across networks. It also relies on a huge infrastructure of routers, Network Access Points (NAPs) and computer systems. Then there are the satellites, miles of cable and hundreds of wireless routers that transmit signals between computers and networks.
