PCOL writes "When Conquistadors came to Peru from Spain in 1532, they were astonished to see Inca suspension bridges achieve clear spans of at least 150 feet at a time when the longest Roman bridge in Spain had a maximum span of 95 feet. The bridges swayed under the weight of traffic terrifying the Spanish and their horses, even though, as one Spaniard observed, they were almost as "sturdy as the street of Seville." To build the bridges, thick cables were pulled across a river with small ropes and attached to stone abutments on each side. Three of the big cables served as the floor of the bridge, two others served as handrails and pieces of wood were tied to the cable floor before the floor was strewn with branches to give firm footing for beasts of burden. Earlier this year students at MIT built a 70-foot fiber bridge in the style of the Incan Empire. The project used sisal twine from the Yucatan Peninsula and anchored it by wrapping it around massive concrete blocks. The weekend's burst of activity was preceded by 360 hours of rope-twisting as the 50 miles of sisal twine was turned into rope. Working together as a group was part of the exercise. "A third of the time was spent learning to work together," one of the students said. "But after a while, we were banging those cables out.""

mcpublic writes "The team of 'digital archaeologists' who developed the technology behind the Intel Museum's 4004 microprocessor exhibit have done it again. 36 years after Intel introduced their first microprocessor on November 15, 1971, these computer historians have turned the spotlight on the first application software ever written for a general-purpose microprocessor: the Busicom 141-PF calculator. At the team's web site you can download and play with an authentic calculator simulator that sports a cool animated flowchart. Want to find out how Busicom's Masatoshi Shima compressed an entire four-function, printing calculator into only 1,024 bytes of ROM? Check out the newly recreated assembly language "source code," extensively analyzed, documented, and commented by the team's newest member: Hungary's Lajos Kintli. 'He is an amazing reverse-engineer,' recounts team leader Tim McNerney, 'We understood the disassembled calculator code well enough to simulate it, but Lajos really turned it into "source code" of the highest standards.'"

Gary writes "A team from the University of Tokyo has genetically engineered a mouse that does not fear cats. By tweaking genes to disable certain functions of the olfactory bulb (the area of the brain that receives information about smells directly from olfactory receptors in the nose) the researchers were able to create a 'fearless' mouse that does not try to flee when it smells cats, foxes and other predators. 'The research suggests that the mechanism by which mammals determine whether or not to fear another animal they smell -- and whether or not to flee -- is not a higher-order cerebral function. Instead, that decision is made based on a lower-order function that is hardwired into the neural circuitry of the olfactory bulb.'"

An anonymous reader writes to mention that hardware hacking enthusiasts can now get their hands on the guts of the Everex TC2502 Linux PC for just $60 (USD). The compact x86-compatible "gOS Dev Board" offers a lightweight Linux-based OS designed for use with Google Apps. " Along with a Firefox browser supporting the Google toolbar, gOS includes local productivity applications, such as OpenOffice.org. However, its main goal is "coherently packaging Google Apps to give users the idea that they can use Google as their main environment," explained Paul Kim, of Everex. "

An anonymous reader writes "A six-person startup is readying a product resembling nothing so much as a set of electronic Legos for device designers. The idea is to provide a set of snap-together components from which engineers can build 'anything,' the company claims, without having to learn solid state electronics. Both hardware and software (Linux/Java phoneME/OSGi) are open source, so that over time, the Lego box will grow, the company hopes. Initially, there's an ARM11-powered base with built-in wifi, and modules for camera, GPS, motion detector, LCD display, keyboard, touchscreen, and stereo speakers. Ooh, and a mysterious 'teleporter,' too."

billdar writes "Terrasoft Solutions posted an article on their development of a stereo vision object detection system built upon Sony's PS3 for Axion Racing's entry into the DARPA Urban Challenge. The PS3 running Yellow Dog Linux replaced one of the on-board Dell servers to process the realtime stereoscopic sensor data. The whole system was developed and integrated onto the vehicle in ten days. So far, Spirit has been making the competition's highlight reels."

Apparently fed up with the lousy service she received from a botched Comcast installation of "triple-play", and a completely humiliating experience at a customer service center, 75-year-old Mona "The Hammer" Shaw took her claw hammer back to the customer service center and bludgeoned the office equipment into tiny plastic pieces."

An anonymous reader writes to mention that IBM Developer Works has a quick look at some of the different projects that are working on replacing proprietary BIOS systems with streamlined code that can load a Linux kernel much faster. Most of the existing BIOS systems tend to have a lot of legacy support built in for various things, and projects like LinuxBIOS and OpenBIOS are working to trim the fat.

An anonymous reader writes "In the summer of 2008, teams from a host of countries will compete in The Microtransat Challenge with the hope of gaining the honor of having built the first autonomous sailboat to cross the Atlantic. The results of Microtransat 2007, a smaller scale preliminary race, were recently announced. The winner was the team from Austria; team RoBoat, for having completed 24 hours of autonomous sailing. I am strongly considering joining this competition before the year is out, and would appreciate any insight from the Slashdot community. The boats can be up to 4 meters in length, and therefore capable of carrying a full-sized onboard computer (operating system of your choice). Time is limited however, so I would like to avoid as many hardware issues as possible and get straight to the difficult problem of writing the AI. So how would you design a seamless interface between sensors and actuators to the high-level code?"

An anonymous reader writes to tell us that some crazy California enthusiasts have built a 21-foot long model of an X-Wing. While this might be impressive in its own right, this model actually flies. Powered by four solid-fuel rocket engines the group has high hopes for their launch next week. Let's hope the built-in R2 unit makes it out ok.

christian.einfeldt writes "James Burgett of the Alameda County Computer Resource Center calls himself a 'tattooed freak' and a recovering drug addict, but CNN is calling him a hero (video) for diverting tons of computers from landfills, installing Ubuntu Linux on them, and giving them out to schools, non-profits, and poor people. Burgett's filmed interview is currently leading a CNN contest among videos of 'ordinary people' whom CNN considers everyday heroes, narrowly edging out the video of a man who is saving gorillas from extinction. In his interview, Burgett points out that the people working for him are also recovering drug addicts or recovering mental illness patients." Update: 10/02 23:46 GMT by KD : Reader stefanlasiewski posted a journal article describing how, bewilderingly, the state of California is threatening to shut down Burgett's ACCRC.

iCry writes "It was rumored last week, and Apple has now confirmed it: 'Apple said today that a firmware update to the iPhone due to be released later this week "will likely result" in SIM-unlocked iPhones turning into very expensive bricks... So what are users of SIM-unlocked iPhones to do? Not run the latest software update, that's for sure. Users can instead pray to the hacking deities — the famed iPhone Dev Team that released the free software unlock, and iPhoneSIMfree, which released a commercial software unlock — to write applications that will undo the unlocks, as it were, if those users want to run the latest iPhone software.'"

An anonymous reader writes "With Steve Jobs' recent announcement of his intention to fight off the independent iPhone developers, the question worth asking is: How will Apple try to defeat the hackers: Software updates, or lawsuits? Will Apple risk losing its most frequently (ab)used legal tool, the Digital Millennium Copyright Act, in order to try and punish the developers of the iPhone unlocking tools? This CNET article explores the legal issues involved in this, which make it perfectly legal to reverse engineer your own iPhone, but illegal to share your circumventing source code with others."
