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?"

avirrey writes "The Technology Review has an interesting article on a Gibson Self-Tuning Guitar. Purist argue that you shouldn't need a guitar that self-tunes. Others argue that this will allow an artist to change tuning with one 'favorite' guitar, instead of having to swap out between songs." Ok I know what I think- freakin' sweet. Only technology will guarantee my sucking on the electric will at least be reasonably in-tune suckiness. Dear Gibson, Slashdot really needs to review your guitar. We'll need several review units and we lost your return address.

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."

Stonent1 writes "Early next month Panasonic is going to release a DVD recorder that can store HD content on standard DVDs. The new device is expected to be a boon for the backer of the Blu-ray format; Blu-ray uses discs several times more expensive than standard DVD media. While the DVD discs won't have the capacity of a Blu-ray disc, the content will be of similar visual quality. 'The company said it will start selling three models of new DVD recorders capable of recording full HD programs on conventional DVD discs on November 1. The high-end model with a 500-gigabyte hard disk drive is likely to sell for 130,000 yen, Matsushita said.'" Update: 10/02 16:18 GMT by Z : Rewritten to clarify.

An anonymous reader writes "Apple's reasoning for keeping the iPhone a closed platform is that they don't want to 'potentially gum up the provider's network'. An article in the New York Times, though, points out that there are hundreds of phones out there working on open platforms that don't seem to be causing network interference. AT&T and Palm, in fact, welcome experimentation on their platforms. In AT&T's case ... on every phone but the iPhone. 'Hackers who have explored the workings of the phone say it uses the frameworks and structures that Apple uses on its other platforms to enable development; it just hasn't been documented. So if Apple is going to allow applications later, is there any reason -- other than vindictiveness or obsessive interest in control -- that it would want to cut off those developed by the pioneers who figured things out ahead of the official launch?'"

An anonymous reader wrote to mention the wonderful news: "A research group funded by U.S. Air Force Research Laboratory is developing a battery which can provide continuous power to your laptop for 30 years! Betavoltaic power cells are constructed from semiconductors and use radioisotopes as the energy source..." Except, not so much. ZDNet's Mixed Signals blog with Rupert Goodwins explains why (as always) if it sounds too good to be true, it probably is: "The sort of atomic structures that generate power when bombarded with high energy electrons are the sort that tend to fall apart when bombarded with high energy electrons. While solar cells have the same problem, it's to a much lesser extent. There's a lot of research into making materials that don't suffer so much, but it remains a serious issue ... while it's true that a tritium-powered battery will eventually turn into an inert, safe lump of nothing much, and while it's also true that a modest amount of shielding will keep the radioactivity within the the battery the while, there's the small problem that if you break the battery during its life the nasties come out."

flowolf writes in with news that Apple seems to be having difficulty getting to grips with a Bluetooth problem on MacBooks. Bluetooth goes unavailable intermittently from what users are assuming is a hardware problem, and while it's out the machines won't stay in sleep mode. Complaints started last spring on the Apple forum, which is still quite active. Many people have had to send their MacBooks for repair more than once without a satisfactory resolution.

DCC writes "TechARP has gotten some juicy news from Intel. This time, it's the top secret details of the Intel 45nm desktop processors, both Yorkfield and Wolfdale with benchmarks and pricing included! 'As promised earlier, Intel will launch their 45 nm processors by the end of this year. In fact, we have been told that the launch date had already been set at November 11, 2007, so mark your calendars. [...] Code-named Yorkfield XE, the Intel Core 2 Extreme QX9650 will be a quad-core processor built from two 45 nm Wolfdale processor dies. It will displace the Core 2 Extreme QX6850 (Kentsfield) processor as the top desktop processor model until Q3, 2008'"

An anonymous reader writes "InfoWeek blogger Alex Wolfe reports that some iPhone users are mad as heck at Apple for bricking up their device in response to non-Apple-authorized software downloads. In a discussion thread on Apple's own iPhone forum, one user posts that he's 'Seeking respondents for possible class action lawsuit against Apple Inc. relating to refusal to service iPhones and related accessories under warranty.' Some who have replied to the post agree that Apple is being unbelievably arrogant and is ripe for legal action. But others say Cupertino is well within its rights to control its own device." Apple seems to have removed the cited post, but it is reproduced as screenshots in the article.

Update: 10/02 02:42 GMT by KD : Reader Cleverboy wrote in to note that the screenshots present in the article are of a posting on Macosrumors, not Apple's forum, and to question the conclusion that Apple removed any posting. The article has been updated since this story went live to make clear that the original posting by user "myndex" was on the Apple forum and was (apparently) removed by Apple; and that the screenshot is of a mirror post myndex made to Macosrumors.

DJ notes that TechARP has up a look at Intel's plans to rebrand their processors, including what must be a leaked internal chart of the old and new landscape of product names. This story doesn't seem to have been picked up anywhere else yet. Quoting: "We just heard from an anonymous source that Intel will be rebranding their processors in 2008... These new brand names will come into effect on the first day of 2008. Intel hopes that these new brands will not only leverage the strong Core 2 brand but also make it less confusing for the consumer. At the moment, the Intel Centrino mobile platform has five different logos with brands like Centrino, Centrino Duo and Centrino Pro. Starting from January 1, 2008, Intel will consolidate the Centrino Duo and Centrino brands under the Intel Centrino brand, and rename the Centrino Pro as Intel Centrino with vPro Technology."

An anonymous reader sends us to a blog posting arguing that, as hardware prices fall below $250 for laptops and desktops, Linux should gain as the Microsoft tax stands out in sharper relief. "In previous years, if you were spending US$1500 and up on a laptop, the Microsoft tax you were paying didn't seem like such a big deal. XP or Vista was pre-installed, fairly convenient... But as the price of hardware for small basic machines comes down, (think under US$250 by the end of next year), then software price starts to become a big issue. Why would you pay the price of your new laptop again just for the software, when all you want to do is really basic things?"

Ian Lamont writes "Mike Elgan at ComputerWorld has an interesting analysis of the small computing market, and predicts that the market is primed to take off. He admits that small computers have been tried before and failed ('Every single UMPC device that has been shipped or announced suffers from lousy usability, high prices, poor performance, ill-conceived user interfaces, or any combination of the above') but he points to several recent products — and a rumor — that he says changes the playing field and paves the way for the first-ever successful small computer, from Apple. The products are the iPhone and the iPod touch. The rumor: Apple Insider has sources who claim that Apple is actually working on a 'modern day Newton' to be released in the first half of 2008. The device will supposedly have a version of Mac OS X Leopard and a touch interface, according to Apple Insider. A lot of people just aren't buying it. They point to the fact that the first Newton eventually flopped. A few note that similar Newton II rumors have been trotted out in years past, as well as a high-profile hoax. Nothing ever came of them." Would you buy if the Newton came back?

mhollis writes "Field experience has confirmed that if you have a hacked iPhone, it will become an iBrick if you use Software Update to install the latest update on your iPhone. The BBC reports: '[Apple's] warning has now proved correct as many owners are reporting their phones no longer work following installation of the update. Apple requires iPhone owners to take out a lengthy contract with AT&T in the United States but there are a number of programs on the net that unlock the device for use with other networks.' The only 'solution' is to unhack your iPhone."
