Bluetooth Versus Wireless Mice

Meneguzzi writes “Having stuck with wired mice for years, I have recently been impressed by a couple of cordless mice I’ve used on other people’s computers so much that I now want to buy one to use with my Mac Book Pro. However, while shopping around for the perfect cordless laptop mouse I was stuck with the question of whether to go for a bluetooth mouse or one of the many proprietary cordless mice with tiny USB receivers. To my surprise, there seems to be little literature systematically comparing these two options for attributes like precision, battery life (both for the mouse and the laptop), RF interference, and whatnot. As a Mac user, bluetooth has the advantage that it won’t take up a USB port, and (in theory), would consume less battery than a USB port, but I wonder if this is actually true in practice. On top of that, I noticed that there are far fewer (and less fancy) options for Bluetooth mice than there are for proprietary cordless ones. Logitech, for instance, has a very basic Bluetooth Mouse, while its proprietary options are much fancier. So I was wondering what are the experiences from Slashdotters on this particular type of hardware, and any recommendations.”

Adobe Confirms PDF Zero-Day, Says Kill JavaScript

CWmike writes “Adobe Systems has acknowledged that all versions of its Adobe Reader, including editions for Windows, the Mac and Linux, contain at least one, and possibly two, critical vulnerabilities. ‘All currently supported shipping versions of Adobe Reader and Acrobat, [Versions] 9.1, 8.1.4 and 7.1.1 and earlier, are vulnerable to this issue,’ said Adobe’s David Lenoe said in a blog entry yesterday. He was referring to a bug in Adobe’s implementation of JavaScript that went public early Tuesday. A “Bugtraq ID,” or BID number has been assigned to a second JavaScript vulnerability in Adobe’s Reader. Proof-of-concept attack code for both bugs has already been published on the Web. Adobe said it will patch Reader and Acrobat, but Lenoe offered no timetable for the fixes. In lieu of a patch, Lenoe recommended that users disable JavaScript in the apps. Andrew Storms, director of security operations at nCircle Network Security, said of the suggestion in lieu of patches, ‘Unfortunately, for Adobe, disabling JavaScript is a broken record, [and] similar to what we’ve seen in the past with Microsoft on ActiveX bugs.'”

IE8 Released As Critical Update For XP

Binestar was one of several readers writing in to note that Microsoft is listing IE8 as a critical update to Windows XP. CNet reported a couple of weeks back that Microsoft would be rolling our IE8 to users in a gradual fashion, and requiring an opt-in before installing it. Opinion has been split as to whether IE8 is worth installing or not. Binestar notes delicately, “For those not interested in upgrading to IE8 at this time, the MSDN released information back in January on how to keep IE8 off your machine.”

Competition Seeks Best Approaches To Detecting Plagiarism

marpot writes “Does your school/university check your homeworks/theses for plagiarism? Nowadays, probably Yes, but are they doing it properly? Little is known about plagiarism detection accuracy, which is why we conduct a competition on plagiarism detection, sponsored by Yahoo! We have set up a corpus of artificial plagiarism which contains plagiarism with varying degrees of obfuscation, and translation plagiarism from Spanish or German source documents. A random plagiarist was employed who attempts to obfuscate his plagiarism with random sequences of text operations, e.g., shuffling, deleting, inserting, or replacing a word. Translated plagiarism is created using machine translation.”

Windows 7’s Virtual XP Mode a Support Nightmare?

CWmike writes “Microsoft’s decision to let Windows 7 users run Windows XP applications in a virtual machine may have been necessary to convince people to upgrade, but it could also create support nightmares, analysts said today. Gartner analyst Michael Silver outlines the downsides. ‘You’ll have to support two versions of Windows,’ he said. ‘Each needs to be secured, antivirused, firewalled and patched. If a company has 10,000 PCs, that’s 20,000 instances of Windows.’ The other big problem Silver foresees: Making sure the software they run is compatible with Windows 7. ‘This is a great Band-Aid, but companies need to heal their applications,’ Silver said. ‘They’ll be doing themselves a disservice if, because of XPM, they’re not making sure that all their apps support Windows 7.'”

IBM Computer Program To Take On ‘Jeopardy!’

longacre writes “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. … The team is aiming not at a true thinking machine but at a new class of software that can ‘understand’ human questions and respond to them correctly. Such a program would have enormous economic implications. … The proposed contest is an effort by I.B.M. to prove that its researchers can make significant technical progress by picking “grand challenges” like its early chess foray. The new bid is based on three years of work by a team that has grown to 20 experts in fields like natural language processing, machine learning and information retrieval. … Under the rules of the match that the company has negotiated with the ‘Jeopardy!’ producers, the computer will not have to emulate all human qualities. It will receive questions as electronic text. The human contestants will both see the text of each question and hear it spoken by the show’s host, Alex Trebek. … Mr. Friedman added that they were also thinking about whom the human contestants should be and were considering inviting Ken Jennings, the ‘Jeopardy!’ contestant who won 74 consecutive times and collected .52 million in 2004.”

What We Can Do About Massive Solar Flares

Reader resistant sends in an update to our discussion a month back on the possibility of violent space weather destroying power grids worldwide during the upcoming solar cycle. Wired is running an interview with Lawrence Joseph, author of “Apocalypse 2012: A Scientific Investigation into Civilization’s End,” and John Kappenman, CEO of electromagnetic damage consulting company MetaTech. The piece brings two new threads to the discussion: the recently discovered presence of an unusually large hole in Earth’s geomagnetic shield, magnifying our vulnerability, and possible steps we can take over the next few years to make the power grid more robust against solar flares and coronal mass ejections. There’s also that whole Mayan 2012 thing. Quoting John Kapperman: “What we’re proposing is to add some fairly small and inexpensive resistors in the transformers’ ground connections. The addition of that little bit of resistance would significantly reduce the amount of the geomagnetically induced currents that flow into the grid. In its simplest form, it’s something that might be made out of cast iron or stainless steel, about the size of a washing machine. …we think it’s do-able for ,000 or less per resistor. That’s less than what you pay for insurance for a transformer. [In the US] there are about 5,000 transformers to consider this for. … We’re talking about 0 million or so. It’s pretty small in the grand scheme of things.”
