KentuckyFC writes "If you live in the city of Bath in the UK and carry a Bluetooth-enabled device, your movements may have been secretly monitored in an experiment designed to test surveillance techniques in prisons. Researchers from Bath University recorded the movements of 10,000 Bluetooth-enabled devices during their 6-month trial. They say the experiment was a test of a technique for monitoring the interactions between prisoners in jail that could be used to work out which inmates have become closely associated. The work was prompted by revelations that the Madrid train bombers who devastated the city in 2004 first met in a Spanish prison (abstract)."

Ian Lamont writes "Apple has filed a patent for IM on portable devices, which could mean that it's getting ready to launch an IM client for the iPhone. The filing is titled 'Portable Electronic Device for Instant Messaging', and covers methods for sending, receiving, and viewing ongoing conversations. The proposed GUI is similar to Apple's current interface for SMS. As for why iChat wasn't enabled for the iPhone earlier, there's some interesting background and analysis here, which also includes a discussion of AIM for the iPhone. IM also came up in the discussions last year about the most-wanted features in iPhone 2.0."

westlake writes "Walter Bender, the former executive director of MIT's Media Lab, and, in many ways, the tireless workhorse and public face of OLPC, has resigned from OLPC after being reorganized and sidetracked into insignificance. The rumor mill would have it that 'constructionism as children [learn] learning' is being replaced by a much less romantic view of the XO's place in the classroom and XO's tech in the marketplace."

Santi Onta writes "Today Lenovo retired the last NON-widescreen laptop they offered (the T61 14.1) from the market, and Lenovo is just an example (Apple, Sony, HP, etc. are the same). I understand the motivation behind all the laptop manufacturers to move to widescreen: they can still advertise that they offer 14.1 or 15.4 screens, but the screen area is smaller, and thus they save more money. Some people might like widescreens (they are useful for some tasks), but any developer knows that vertical space matters! Less vertical space = less lines of code in the screen = more scrolling = less productivity. How can laptop manufacturers still claim that they look after their customers when the move to widescreens is clearly a selfish one? I just wish they offered non-widescreen laptops, even if it were for a plus (that I'd be more than happy to pay)." I've always preferred the widescreen aspect ratio -- vertical matters, but having two nice wide columns always mattered more to me. Until this reader's submission, I hadn't realized that it was such a contested issue. Does this matter?

Oleg.salenko points out a ComputerWorld story with some bad news for Russia's wireless users, which starts out "Business travelers to Russia might want to keep their laptops and iPhones well-concealed — not from muggers, necessarily, but from the country's recently formed regulatory super-agency, Rossvyazokhrankultura (short for the Russian Mass Media, Communications and Cultural Protection Service)... Rossvyazokhrankultura's interpretation of current law holds that users must register any electronics that use the frequency involved in Wi-Fi communications, said Vladimir Karpov, the deputy director of the agency's communications monitoring division, according to an English commentary provided by website The Other Russia."

otakuj462 writes "Many participants in OLPC's 'Give 1 Get 1' program of last November are now encountering what has come to be known as the 'stuck key' problem, in which one or more of the keys on their XO-1 laptop's built-in keyboard become stuck in an activated position, or are activated when adjacent keys are pressed. As of January 30th, the official word from OLPC is that the root cause of this problem is unknown because '[t]here are several manufacturers of the keyboards.' ('So far we don't know of any _reliable_ method of fixing the keyboard or the exact root cause.') It is unknown just how widespread this problem currently is, as the 30-day manufacturer's warranty has already expired for most G1G1 participants. However, the OLPC forums are full of reports. OLPC is currently deploying the XO-1 to children in Mongolia and Peru, as well as other developing nations. If OLPC is actively deploying units with known, critical hardware bugs, without a dedicated support infrastructure in place, to children who have never seen a computer before, should they still be considered to be a responsible organization? Did OLPC deploy their hardware too soon?"

NW writes "While universities like MIT, Berkeley and CMU don't tend to shout as loudly about their latest tech innovations as do Google, Cisco and other big vendors, their results are no less impressive in what they could mean for faster, more secure and more useful networks, computers, etc. Here's a good roundup of 25 of them, from studies on putting T-Rays to use in computers to advancing wireless to the next level to outsmarting terrorists on the Web."

BarlowBrad writes "Yesterday my house was broken into and among other things two laptops were stolen. Getting past the feeling of violation, I am looking to the future and how to both prevent theft and recover computers should it happen again. I have found various services that claim to track and recover stolen laptops such as LoJack for Laptops, Computrace, GadgetTrak and Undercover, but I (obviously) have no experience with any of them. I also know that Intel will be coming out with a new anti-theft technology chip, but that isn't supposed to come out until the fourth quarter and I'll be replacing the laptops before then. Does Slashdot have a recommendation between these services or suggestions for another?" Read on for a related question about automating this process.

MaineCoasts writes "The Times Online reports that European sellers of the iPhone are braced for 'significant losses' on unsold inventories of first-generation iPhones which must be cleared away for the new 3G versions expected in June. The three European distributors of the iPhone 'sold 330,000 units to the end of December, but industry sources say that European sales of the iPhone were forecast to be between 500,000 and 600,000.'"

Ninjakicks writes "Hard drives are typically one of the more significant performance bottlenecks in any system today. An evaluation of Lenovo's new ultra portable Thinkpad X300 notebook shows a fast solid state hard drive can substantially improve the performance of a system. This is especially true of a low-end, low power processor and integrated graphics, in addition to reducing overall power consumption. Despite its 1.2GHz CPU the Thinkpad X300 is actually able to outperform some desktop replacement notebooks equipped with dual 7200RPM hard drives in RAID 0 in productivity benchmarks, and in data transfers. Interesting results, especially considering the X300's ultra portable form factor."

alphadogg writes "Despite the fact that it's often considered an illegal act, a sizeable percentage of the UK/US internet-using population 'borrows' unsecured Wi-Fi access. This is according to a study conducted by the group Accenture. 'The Accenture study found that computer users are still engaging in some unsafe computing practices. Nearly half of all respondents said that they used the same password for all of their online accounts, and only a quarter of them have ever encrypted files on their computers.'" My guess is the actual figure is higher than that.

An anonymous reader writes "After months of rumors, the new 8.9in screen Eee PC is out in the open and the first review is online. As well as the larger screen you get 1GB RAM, 20GB Storage and a multi-touch touchpad. It costs more than the old Eee PC, but it definitely sounds like it's worth the extra cash." I always thought the appeal of the original was the ridiculously low price, coupled with the ease of hacking. Not sure if the sequel will meet that challenge.

An anonymous reader writes "This weekend I spent half a day surfing the web looking for a new laptop. I just want (to be able to switch to) 1650x1280, or at least ...x1024, and a *non*-Glossy Display . To my surprise I found out that many vendors leave me not that much choice: ...x800, and glossy, i.e., higher-reflective type screens seem to have become the promoted defaults. Should I give up on my non-glossy wishes, or should I start flaming vendors?" I still can't understand the glossy screens. They make my eyes hurt almost immediately in any sort of ambient light, and do nothing in low light. Glossy laptop screens are like TVs on the shelf in the store with their colors all whacked out to look brighter. Once you get them into the real world, you realize that the colors are just wrong.

cheapbob writes "Recently HP officially unveiled a budget ultraportable laptop aimed to compete with the likes of Asus Eee PC. According to Compal, one of Dell's assemblers, Dell is also going to enter the budget ultra-portable market soon. All of these devices lack many of the features associated with larger-sized laptops, such as optical drives and large amounts of storage space, yet demand for them is very high. Initial reviews of these devices unsurprisingly expose them to be underpowered and lacklustre. What's the appeal? What do you think is the perfect balance of features and price point for a budget laptop?"

mattnyc99 writes "Last month we learned that the UK has approved in-flight mobile, effective immediately. Popular Mechanics has a follow-up on why the phones-on-planes ban is here to stay in the United States. Statements from the FCC and FAA confirm that any chance to overturn it remains dead on arrival — even though new "pico-cell" networks cut down interference with phones on the ground. American Airlines is looking like it will have onboard Wi-Fi within the next couple months, just the same. PM does note, however, that if the European mobile rollout is a success, US carriers might just have to give into demand."

canadacow writes "iPhone developers enrolled and active in the iPhone OS 2.0 beta program got a nasty surprise today when Apple inadvertently 'expired' the recently released version. While for a beta program this typically would not be an issue, Apple has yet to release a new deployment of the iPhone OS. So developers like myself who use their iPhone for both actual phone and iPod use are bricked. Of note, this particular expired build is just 11 days old."

Ryan writes "HP had unveiled their version of a miniaturized laptop for school kids. The tiny device boasts speeds up to 1.6 gigahertz. They haven't yet decided on a name, but 'netbooks' is one possibility. They will be used for surfing the Internet and doing other basic tasks like word processing. The company plans to have 50 million units available in the marketplace by 2011. Optical drives have been left out to prevent kids from playing 'unauthorized games.' Weighing less than 3 pounds with a tiny 8.9 inch screen, the machines start below $500 for a Linux-based model. Prices are expected to be higher for Windows Vista models."

eldavojohn writes "Now that Verizon has beaten Google in the 'block C' spectrum auction, what are they going to do with it? Well, as of today they've revealed their plans for world domination: they plan to speed up wireless internet connections. It may come as no surprise that they'll also be making this available for other manufacturer's devices. AT&T plans to do the same with their auction winnings, 'AT&T was second to Verizon, winning $6 billion in spectrum licenses, which it also plans to use for high-speed Internet service. But its executives said they didn't bid for the portion subject to the open-access rules. The parts it did land cost AT&T nearly three times as much per unit of spectrum than the portion Verizon bought.'"

An anonymous reader writes to share that while the new items at CTIA may be a bit underwhelming, there are still a few things that should fuel interest. "The Pro-700 is a rugged device certified to military standards for dust, shock and vibration which should get a few of the rabble smearing mud across their cheeks in readiness for the forthcoming assault. For the rest of us it offers a single-number option and the ability to black or allow incoming one-to-one push-to-talk calls. With Sprint Mobile Sync, an online tool that lets users manage all of their contact information online, including setting up groups for PTT and text/voice messaging the Pro-700 is a formidable package."

webarnold writes "A new concept computer is being designed to look like a tea cup. Using holographic projectors, view your data inside the cup, 'spilled' onto the table, or transfer it to other Cup PC users by pouring data into their cup." Acceptance of something like this seems a bit far-fetched given current tech, but no nomad-space comparisons are being made.
