 | Defying Experts, Rogue Computer Code Still Lurks | 8.27.2009 | It is still out there.
Like a ghost ship, a rogue software program that glided onto the Internet last November has confounded the efforts of top security experts to eradicate the program and trace its origins and purpose, exposing serious weaknesses in the world’s digital infrastructure.
The program, known as Conficker, uses flaws in Windows software to co-opt machines and link them into a virtual computer that can be commanded remotely by its authors. With more than five million of these zombies now under its control — government, business and home computers in more than 200 countries — this shadowy computer has power that dwarfs that of the world’s largest data centers.
Alarmed by the program’s quick spread after its debut in November, computer security experts from industry, academia and government joined forces in a highly unusual collaboration. They decoded the program and developed antivirus software that erased it from millions of the computers. But Conficker’s persistence and sophistication has squelched the belief of many experts that such global computer infections are a thing of the past.

| Lost in the Cloud | 7.20.2009 | EARLIER this month Google announced a new operating system called Chrome. It’s meant to transform personal computers and handheld devices into single-purpose windows to the Web. This is part of a larger trend: Chrome moves us further away from running code and storing our information on our own PCs toward doing everything online — also known as in "the cloud" — using whatever device is at hand.
Many people consider this development to be as sensible and inevitable as the move from answering machines to voicemail. With your stuff in the cloud, it’s not a catastrophe to lose your laptop, any more than losing your glasses would permanently destroy your vision. In addition, as more and more of our information is gathered from and shared with others — through Facebook, MySpace or Twitter — having it all online can make a lot of sense.
The cloud, however, comes with real dangers.

| Data Center Overload | 6.15.2009 | It began with an Xbox game.
On a recent rainy evening in Brooklyn, I was at a friend’s house playing (a bit sheepishly, given my incipient middle age) Call of Duty: World at War. Scrolling through the game’s menus, I noticed a screen for Xbox Live, which allows you to play against remote users via broadband. The number of Call of Duty players online at that moment? More than 66,000.
Walking home, I ruminated on the number. Sixty-six thousand is the population of a small city — Muncie, Ind., for one. Who and where was this invisible metropolis? What infrastructure was needed to create this city of ether?
We have an almost inimical incuriosity when it comes to infrastructure. It tends to feature in our thoughts only when it’s not working. The Google search results that are returned in 0.15 seconds were once a stirring novelty but soon became just another assumption in our lives, like the air we breathe. Yet whose day would proceed smoothly without the computing infrastructure that increasingly makes it possible to navigate the world and our relationships within it?
Much of the daily material of our lives is now dematerialized and outsourced to a far-flung, unseen network. The stack of letters becomes the e-mail database on the computer, which gives way to Hotmail or Gmail. The clipping sent to a friend becomes the attached PDF file, which becomes a set of shared bookmarks, hosted offsite. The photos in a box are replaced by JPEGs on a hard drive, then a hosted sharing service like Snapfish. The tilting CD tower gives way to the MP3-laden hard drive which itself yields to a service like Pandora, music that is always “there,” waiting to be heard.
But where is “there,” and what does it look like?

| Contractors Vie for Plum Work, Hacking for U.S. | 6.1.2009 | MELBOURNE, Fla. — The government’s urgent push into cyberwarfare has set off a rush among the biggest military companies for billions of dollars in new defense contracts.
The exotic nature of the work, coupled with the deep recession, is enabling the companies to attract top young talent that once would have gone to Silicon Valley. And the race to develop weapons that defend against, or initiate, computer attacks has given rise to thousands of “hacker soldiers” within the Pentagon who can blend the new capabilities into the nation’s war planning.

| G.E.’s Breakthrough Can Put 100 DVDs on a Disc | 4.28.2009 | General Electric says it has achieved a breakthrough in digital storage technology that will allow standard-size discs to hold the equivalent of 100 DVDs.
The storage advance, which G.E. is announcing on Monday, is just a laboratory success at this stage. The new technology must be made to work in products that can be mass-produced at affordable prices.
But optical storage experts and industry analysts who were told of the development said it held the promise of being a big step forward in digital storage with a wide range of potential uses in commercial, scientific and consumer markets.
“This could be the next generation of low-cost storage,” said Richard Doherty, an analyst at Envisioneering, a technology research firm.
The promising work by the G.E. researchers is in the field of holographic storage. Holography is an optical process that stores not only three-dimensional images like the ones placed on many credit cards for security purposes, but the 1’s and 0’s of digital data as well.
The data is encoded in light patterns that are stored in light-sensitive material. The holograms act like microscopic mirrors that refract light patterns when a laser shines on them, and so each hologram’s recorded data can then be retrieved and deciphered.

| Computer Program to Take On 'Jeopardy!' | 4.28.2009 | YORKTOWN HEIGHTS, N.Y. — This highly successful television quiz show is the latest challenge for artificial intelligence.
What is “Jeopardy”?
That is correct.
I.B.M. plans to announce Monday that it is in the final stages of completing a computer program to compete against human “Jeopardy!” contestants. If the program beats the humans, the field of artificial intelligence will have made a leap forward.
I.B.M. scientists previously devised a chess-playing program to run on a supercomputer called Deep Blue. That program beat the world champion Garry Kasparov in a controversial 1997 match (Mr. Kasparov called the match unfair and secured a draw in a later one against another version of the program).
But chess is a game of limits, with pieces that have clearly defined powers. “Jeopardy!” requires a program with the suppleness to weigh an almost infinite range of relationships and to make subtle comparisons and interpretations. The software must interact with humans on their own terms, and fast.

| How the Internet Got Its Rules | 4.9.2009 | TODAY is an important date in the history of the Internet: the 40th anniversary of what is known as the Request for Comments. Outside the technical community, not many people know about the R.F.C.’s, but these humble documents shape the Internet’s inner workings and have played a significant role in its success.
When the R.F.C.’s were born, there wasn’t a World Wide Web. Even by the end of 1969, there was just a rudimentary network linking four computers at four research centers: the University of California, Los Angeles; the Stanford Research Institute; the University of California, Santa Barbara; and the University of Utah in Salt Lake City. The government financed the network and the hundred or fewer computer scientists who used it. It was such a small community that we all got to know one another.
A great deal of deliberation and planning had gone into the network’s underlying technology, but no one had given a lot of thought to what we would actually do with it. So, in August 1968, a handful of graduate students and staff members from the four sites began meeting intermittently, in person, to try to figure it out. (I was lucky enough to be one of the U.C.L.A. students included in these wide-ranging discussions.) It wasn’t until the next spring that we realized we should start writing down our thoughts. We thought maybe we’d put together a few temporary, informal memos on network protocols, the rules by which computers exchange information. I offered to organize our early notes.
What was supposed to be a simple chore turned out to be a nerve-racking project.

| Vast Spy System Loots Computers in 103 Countries | 3.30.2009 | 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.

| A Software Populist Who Doesn’t Do Windows | 1.12.2009 | THEY’RE either hapless pests or the very people capable of overthrowing Windows. Take your pick.
In December, hundreds of these controversial software developers gathered for one week at the Google headquarters in Mountain View, Calif. They came from all over the world, sporting many of the usual signs of software mercenaries: jeans, ponytails, unruly facial hair and bloodshot eyes.
But rather than preparing to code for the highest bidder, the developers were coordinating their largely volunteer effort to try to undermine Microsoft’s Windows operating system for PCs, which generated close to $17 billion in sales last year.
All the fuss at the meeting centered on something called Ubuntu and a man named Mark Shuttleworth, the charismatic 35-year-old billionaire from South Africa who functions as the spiritual and financial leader of this coding clan.
Created just over four years ago, Ubuntu (pronounced oo-BOON-too) has emerged as the fastest-growing and most celebrated version of the Linux operating system, which competes with Windows primarily through its low, low price: $0.

| Archimedes and the 2000-year-old computer | 12.22.2008 | MARCELLUS and his men blockaded Syracuse, in Sicily, for two years. The Roman general expected to conquer the Greek city state easily, but the ingenious siege towers and catapults designed by Archimedes helped to keep his troops at bay.
Then, in 212 BC, the Syracusans neglected their defences during a festival to the goddess Artemis, and the Romans finally breached the city walls. Marcellus wanted Archimedes alive, but it wasn't to be. According to ancient historians, Archimedes was killed in the chaos; by one account a soldier ran him through with a sword as he was in the middle of a mathematical proof.
One of Archimedes's creations was saved, though. The general took back to Rome a mechanical bronze sphere that showed the motions of the sun, moon and planets as seen from Earth.
The sphere stayed in Marcellus's family for generations, until the Roman author Cicero saw it in the first century BC. "The invention of Archimedes deserves special admiration because he had thought out a way to represent accurately by a single device for turning the globe those various and divergent movements with their different rates of speed," he wrote. "The moon was always as many revolutions behind the sun on the bronze contrivance as would agree with the number of days it was behind it in the sky."
Until recently, historians paid scant attention to this story: the description suggests a sophisticated mechanical device, beyond anything the ancient Greeks were thought to have been capable of. Furthermore, Cicero had no technical training, and did not explain how the device worked. He could have made the story up for effect.
Now, however, research on the battered remains of a mysterious ancient device suggests that Cicero was telling the truth. While the Antikythera mechanism is not the same one seen by Cicero - it was not made until a century later - it proves that clockwork mechanisms like the one he described really did exist, and that ancient Greek technology was far more advanced than thought. Freshly deciphered inscriptions on its dials also hint at the origins of this technology.
 The device was discovered more than a century ago by sponge divers from the Aegean island of Symi. In 1900, after a gale blew them off course, they took shelter by a barren islet called Antikythera. When the storm abated, they went diving. Instead of sponges, the divers found a large heap of bronze and marble statues. They had happened upon an ancient shipwreck.
The Greek government immediately hired the men to salvage the wreck. It was dangerous work: during the 10-month expedition one of the men died and two were paralysed as a result of the bends. But they brought back incredible treasures: bronze and marble statues, jewellery, glassware and furniture, including an ornate bronze throne.
In all the excitement, nobody noticed a corroded lump of rock dumped in a crate in the courtyard of the National Archaeological Museum in Athens. That changed a few months later when it cracked open, revealing traces of gearwheels, precisely marked circular scales and inscriptions in ancient Greek.
The battered artefact became known as the "Antikythera mechanism", and it caused excitement and consternation. Until then, not one gearwheel, pointer or scale had been found from antiquity. Nor have any been found since; the Antikythera mechanism remains unique.
