Meet the 2,100-Year-Old Computer From Ancient Greece

More Details Paint 2,100 Year Old Greek Computer as Calendar

If your definition of computer is a beige box with a keyboard and mouse sprouting out of the back, then prepare to have your horizons expanded a bit. Back in 1900, a device called the Antikythera Mechanism was discovered in a ship's wreckage near a Greek island of the same name. For years researchers weren't really sure what the thing did, but recent examinations -- published on Wednesday in 'Nature' magazine -- are shedding much more light into its ability to function as a calendar, and even to track the Olympic games.

It's believed the device used a set of gears to correlate lunar months to calendar months. Recent high-resolution X-ray scans have enabled researchers to read engravings on the device, identifying the names of months and, interestingly, the words relating to the locations of the Olympic games.

The four-year cycle of years leading to the competitions was a common way for Greek citizens to mark the passage of time, with the games themselves taking on religious significance. This year's Olympics are taking on a rather different significance when it comes to computers, unfortunately. [Source: The New York Times and AP]

Man Arrested for Running Into Burning Building to Get Computer

Man Saves Computer From Burining Building, Not Treated as HeroWe've all seen the stories where a noble passer-by runs into a burning building to save a stranded baby or animal before the firemen are able to get there and do the same. Such people usually receive 15 minutes of fame on the local news, the key to the city, and, of course, an overwhelming feeling of well-being.

Given our reliance on computers today, a lot of people are also quite devastated if their precious data is destroyed by fire, but a word of caution: Should you be thinking of pulling the hero move next time a house burns down, then the legal charges filed against a Minnesota man for doing just that might make you think twice.

The man, 53-year-old Nicholas Guy, lived in an apartment complex with a number of other tenants in Winona, Minnesota. The fire department responded to a call placed at 7:43pm and was on the scene attempting to put out a blaze that started on the first floor before spreading to the attic. Guy, who was drunk, disobeyed police orders and snuck into the building to retrieve his computer, but then needed help to get back out again.

He was charged with disorderly conduct and for obstructing a fire scene, crimes that won't land him in jail, but could result in some hefty fines. [Source: Winona Daily News]

Inventor of First Business Computer Dies



What if the latest technology news came not out of Microsoft or Apple but instead from McDonald's or Pizza Hut? It would be surprising news, to say the least. Even so, it turns out that one of the biggest advances in computer tech for business was developed by an English food company back in 1951, and its principal designer, David Caminer, died on June 15 at the age of 92.

Caminer is credited by Guinness World Records with creating the world's first business computer on behalf of his employer, J. Lyons & Co, which operated a chain of bakeries and food shops. While other companies, such as IBM, soon overtook the British firm (due to what Caminer said was arrogance and a failure to appreciate the rapid pace of technology by his employer), it is Caminer who gets the credit for devising the business machine. Its first task was to calculate costs, prices and margins of that week's baked output.

Caminer's goal was to speed up the logistics and payroll process for Lyons, which besides running stores also served events at Wimbledon and Windsor Castle. While it took an accountant eight minutes to calculate an employee's pay, the computer, called LEO (short for Lyons Electronic Office), needed only 1.5 seconds. Although the LEO 1 has less than 100,000th the power of a current desktop personal computer it did have all those cool vacuum tubes. They hummed.

What was one thing Caminer did have in common with other great technology inventors? No college degree. (But to all you kids out there, Switched says "Be cool. Stay in school.")

The real innovation of Caminer's machine was that it could be loaded with different programs to work on different tasks. And thus modern business computing was born. [Source: The Seattle Times]

$50 PC Will Teach Chicago School Kids



Here's another entry in the expanding line of low-cost computer technology that's geared towards the classroom: Innovations for Learning, a Chicago-based nonprofit, recently debuted its $50 Teachermate handheld, which now joins the OLPC XO and Intel Classmate in the quest to teach kids how to compute on the cheap. The bare-bones PC comes with 512MB of RAM, an SD slot (for external memory), a tiny 2.5-inch display, and a microphone and speaker. It lacks Wi-Fi (wireless connectivity) or Ethernet, however, so the Teachermate won't be able to go online. Because the handheld device also lacks a keyboard, it forces the user to maneuver around the onscreen interface with just a four-way directional pad and three buttons.

Innovations for Learning will be launching the new computers in over 500 Chicago public elementary schools during the next two years. While both the OLPC and Intel Classmate are built on freely-available open-source software -- which makes them more versatile and upgradeable -- the Teachermate currently only runs a small proprietary set of classroom management tools and reading and math educational software.

The Teachermate will be available soon on Amazon, for those who are interested in trying it out on their own.

Sears One-Ups Wal-Mart With $185 PC

Sears One-Ups Wal-Mart with $185 Linux PC
We have a new reigning champion in the competition for the world's cheapest desktop computer. Sears.com is now selling a Mirus-built, Linux-based desktop PC for $285. We know, we know -- what about the OLPC XO or the Wal-Mart Everex Green PC?" ) Well, friends, what makes the Sears Mirus PC cheaper, for a limited time anyway, is a $100 mail-in rebate, making it total out to $185, which is $15 cheaper than the Green PC and $3 cheaper than the XO.

The Intel Celeron-based system also comes with 1-gigabyte of memory, giving it significantly more horsepower than anything else out at this price point.

The Mirus is part of a larger trend towards low cost, low power, Linux-running systems (Linux is an open-source operating system that's generally more stable than Windows and Mac operating systems). The OLPC XO, the Asus Eee, the Green PC, and the upcoming Intel powered MIDs are all aimed at users who just need typical daily computer functions such as word processing, image and music management, and Web access. Linux already owns the server market (almost every Web site you visit is sitting on a Linux-based server), and is now beginning to make a mark on the low-cost PC market.

If things continue along this route, 2008 will be the year that Linux finally becomes a household word.

MacBook Design Flaw Can Lead to Permanent Data Loss



Apple MacBook and MacBook Pro owners should be aware of a design flaw that may lead to unrecoverable data loss, claims Retrodata, a data-recovery firm based out of the United Kingdom. The company says that MacBooks manufactured in China and equipped with a 2.5 inch Seagate SATA hard drive with a Firmware version 7.01 may have faulty read/write heads that become dislodged from the hard drive's arm, scratching the magnetic platter surface and causing irrecoverable data loss.

For those customers who wish to know whether they are at risk, Retrodata suggests going to the System Profiler and checking the Serial ATA for the Firmware Revision number. If the computer has Firmware version 7.01, data should be backed up immediately, the company urges. Models affected may include ST96812AS and ST98823AS.

Not so fast, say specialists from other data-recovery companies like DiskEng. While Apple has been silent and Seagate insists that they are looking into the matter, these parties suggest that thousands of instances of the same problem must first be seen and diagnosed before a design flaw can be pronounced for an entire line of hard drives. Some say specific factors such as temperature and read/write head oscillation may be to blame for damaging some computers rather than a general design shortcoming that affects them all.

Just to be safe, consumers should check whether their computer has the specific hard drive in question, and should back up their files if that is the case. Those concerned should also monitor Apple and Seagate pronouncements regarding the issue.

Junk-Food-Detecting Shopping Carts Coming Soon?

Shopping Cart Detects Junk Food
Sure, you've got TV and your friends to remind you not to eat certain foods and tell you that you're a fatty, but what if your shopping cart told you before you even got out of the super market?

US-based technology company EDS imagines such a world, where intelligent shopping carts scan bar codes on food as you load them into your cart, giving you nutritional and ethical information about the products (as well as price) you're about to eat. While the carts don't exist yet, they were outlined in a research paper published by EDS this week.

The concept carts are fitted with touch-screen computers that track the nutritional value of everything loaded into your cart. They tell you when you've exceeded a certain caloric limit or when your cart contains too many saturated fats, sodium, or carbohydrates. These smart-carts also save on packaging, since labels could be shed if consumers had access to nutritional information stored on the bar codes.

Says EDS, "It's high-time that the humble barcode is recognized as a practical and cost-effective solution to consumers' thirst for information."

The Computer That Reads Your Mood



Imagine a future where your computer knows when you're feeling stressed and adjusts to you accordingly. The same system can also, say, sense when an air traffic controller is feeling burned out, and pass the next airplane landing on to someone else -- automatically.

Well, with $445,000 from the National Science Foundation, researchers at Tufts University are hoping to make such a system a reality.

The project uses near infrared light to monitor blood flow in the brain. The near infrared light passes through the human body, but is absorbed by oxygenated and deoxygenated hemoglobin in blood cells. Researchers believe that by watching for increased flow of oxygenated blood to certain areas of the brain, they can monitor stress levels. Eventually, these stress levels could be checked automatically by a computer, which would adjust its interface in subtle ways to relieve said stress. (Or just force you off the system if you're doing something life-or-death-threatening like landing planes!)

Researchers made no mention of specifically how the computer might change its interface, only that it would be lightweight changes -- maybe dimmer lighting or fewer onscreen animations? -- to reflect the often subtle and imperfect information they glean from the readings.

Sweaty Man Electrocuted By PC - and Other Gadget-Related Deaths

PC Power SupplySeems tech has a contract out for geeks.

Let this be a warning to all of you: Don't touch the inside of your PC when you are wet. According to Shanghai Daily, a young man, simply identified as "Wu," was shocked to death by his PC.

Wu took the case off the outside of his PC to prevent it from overheating. For some unexplained reason, he was not running the air conditioner in his home, so he wasn't wearing that much clothing. At some point, his sweaty leg came in contact with his PC's innards and Wu was dealt the deadly jolt -- 380 volts right from his PC's power supply.

Let's not forget that gadgets are electric, after all, and these kinds of deaths can happen just like that, so follow the precautions you'd take with any other electricity-powered device (like don't touch it if you're wet!).

But electrocution is not the only hazard that can come with a gadget. Take a look at some of the other tech-related deaths we have covered in the past few months (surprisingly, there are a lot more than just these).

We hope each of the following examples will serve as some kind of warning for you:

Don't Mess With Sun

Moving your company to cheap new office space in downtown Baghdad? Sun Microsystems has you covered with Project Blackbox, a prototype datacenter built inside of a giant metal shipping container. It's a 'portable,' instant computing infrastructure (space for up to 500 CPUs) that can be quickly and easily deployed anywhere.

And it's no coincidence that this monster shares its name with the indestructible flight recorder used on planes. Just witness this fairly dated, but nonetheless amazing video in which Sun subjects its Blackbox to a magnitude 6.7 earthquake on a simulator in Northridge, CA. It survives with just a few bumps and bruises. More importantly, it keeps running, with just a few failures technicians chalk up to power cords shaking loose (skip to about halfway through the video).
