U of M laser mimics helicopter heat signatures to thwart missiles


Researchers at the University of Michigan have developed a new laser-based countermeasure for aircraft, and unlike others we've seen (and we've seen a few) this technology aims to "blind" missiles rather than knock 'em out of the sky. The system uses a mid-infrared supercontinuum laser to mimic the heat signature of a helicopter, and it has no moving parts -- making it rugged enough to last a long time on rotor-based aircraft. The school has even spun off a company, Omni Sciences, to develop the thing, and has received some $1 million in grants from the Army and DARPA to build a second-generation prototype. Of course, questions remain: is it really a wargadget if you can't blow something up with it? And even if it is, where's the fun in that?

Best Way To Archive Emails For Later Searching?

An anonymous reader writes "I have kept every email I have ever sent or received since 1990, with the exception of junk mail (though I kept a lot of that as well). I have migrated my emails faithfully from Unix mail, to Eudora, to Outlook, to Thunderbird and Entourage, though I have left much of the older stuff in Outlook PST files. To make my life easier I would now like to merge all the emails back into a single searchable archive — just because I can. But there are a few problems: a) Moving them between email systems is SLOW; while the data is only a few GB, it is hundred of thousands of emails and all of the email systems I have tried take forever to process the data. b) Some email systems (i.e. Outlook) become very sluggish when their database goes over a certain size. c) I don't want to leave them in a proprietary database, as within a few years the format becomes unsupported by the current generation of the software. d) I would like to be able to search the full text, keep the attachments, view HTML emails correctly and follow email chains. e) Because I use multiple operating systems, I would prefer platform independence. f) Since I hope to maintain and add emails for the foreseeable future, I would like to use some form of open standard. So, what would you recommend?"

Hands-on With the iPad Alternatives On Display at IFA

Barence writes "This week's IFA show has seen a flurry of Android-based alternatives to the iPad emerge from leading manufacturers. The Samsung Galaxy Tab made a strong first impression on PC Pro's reviewer. The 7-inch tablet's TFT screen 'beams forth with rich, saturated colours and wide, wide viewing angles,' the device is capable of Full HD playback and the TouchWiz UI is 'clearly intended to draw customers away from the iFamily.' Elsewhere, ViewSonic has launched a pair of 7-inch and 10-inch tablets, the larger of which dual boots into either Android or Windows 7. 'Our first moments with Windows 7 were surprisingly painless, too: we expected the Atom processor and 1GB of memory to be horrendously sluggish, but it wasn't the case,' PC Pro reports. Finally, Toshiba's 10.1in Folio 100 marries Android 2.2 with Nvidia's Tegra 2 platform to deliver 'mighty graphics crunching power.' The build quality left a little to desire, though. 'The 14mm thick chassis feels lightweight, and even relatively gentle twisting motions left the Folio's plastic body creaking under the stress.'"

Aging Star System Leaves Strange Death Spiral

jamie tips a post at Phil Plait's Bad Astronomy blog about an extremely unusual astronomical phenomenon originating from a binary system about 3000 light years away. Quoting:
"The name of this thing is AFGL 3068. It's been known as a bright infrared source for some time, but images just showed it as a dot. This Hubble image using the Advanced Camera for Surveys reveals an intricate, delicate and exceedingly faint spiral pattern. ... Red giants tend to blow a lot of their outer layers into space in an expanding spherical wind; think of it as a super-solar wind. The star surrounds itself with a cloud of this material, essentially enclosing it in a cocoon. In general the material isn't all that thick, but in some of these stars there is an overabundance of carbon in the outer layers which gets carried along in these winds. ... AFGL 3068 is a carbon star and most likely evolved just like this, but with a difference: it's a binary. As the two stars swing around each other, the wind from the carbon star doesn't expand in a sphere. Instead, we see a spiral pattern as the material expands."

American Business Embraces 'Gamification'

Hugh Pickens writes "JP Mangalindan writes that for years psychologists have studied what makes video games so engrossing — why do players spend hours accruing virtual points working towards intangible rewards and what characteristics make some games more addictive than others? Now, companies are realizing that 'gamification' — using the same mechanics that hook gamers — is an effective way to generate business. For example, when Nike released Nike + in 2008, it 'gamified' exercise. 'Place the pedometer in a pair of (Nike) sneaks and it monitors distance, pace and calories burned, transmitting that data to the user's iPod. The Nike software loaded on the iPod will then "reward" users if they reach a milestone,' writes Mangalindan. 'If a runner beats his 5-mile distance record, an audio clip from Tour de France cycling champ Lance Armstrong congratulates him.' In addition, users can upload their information, discuss achievements online with other users, and challenge them to distance or speed competitions. The result: to date, Nike has moved well over 1.3 million Nike + units."

Programming Things I Wish I Knew Earlier

theodp writes "Raw intellect ain't always all it's cracked up to be, advises Ted Dziuba in his introduction to Programming Things I Wish I Knew Earlier, so don't be too stubborn to learn the things that can save you from the headaches of over-engineering. Here's some sample how-to-avoid-over-complicating-things advice: 'If Linux can do it, you shouldn't. Don't use Hadoop MapReduce until you have a solid reason why xargs won't solve your problem. Don't implement your own lockservice when Linux's advisory file locking works just fine. Don't do image processing work with PIL unless you have proven that command-line ImageMagick won't do the job. Modern Linux distributions are capable of a lot, and most hard problems are already solved for you. You just need to know where to look.' Any cautionary tips you'd like to share from your own experience?"

M2Z's Free, Wireless Broadband Killed In Advance

mspohr writes with a sad excerpt from Fast Company: "Despite a seemingly stout business plan, and all the financial, social, and educational benefits it would bring, the FCC's just turned down M2Z's application for a coast-to-coast free wireless broadband system. ... The FCC is known to have heard complaints about M2Z's plan from existing wireless carriers. Though M2Z's network would've operated at under 1 Mbps peak speeds — meaning it was very slow by today's standards, and probably snail-like by tomorrow's — its free pricing may well have tempted many folks away from spending cash with an established ISP. Those carriers are now reported to be pleased with the FCC's decision, though they argue it's in line with the greater National Broadband Plan. Whenever that actually gets off the ground."

Google Says Microsoft Is Driving Antitrust Review

GovTechGuy writes "On Friday we discussed news that Texas Attorney General Greg Abbott opened a probe into whether Google ranks its search listings with an eye toward nicking the competition. Google suggested the concerns have a major sponsor: Microsoft. In question is whether the world's biggest search engine could be unfairly disadvantaging some companies by giving them a low ranking in free search listings and in paid ads that appear at the top of the page. That could make it tough for users to find those sites and might violate antitrust laws. Abbott's office asked for information about three companies who have publicly complained about Google, according to blog post by Don Harrison, the company's deputy general counsel. Harrison linked each of the companies to Microsoft."

UK's Royal Mail Launches First Intelligent Stamps

An anonymous reader writes "The Royal Mail on Friday issued what it called the world's first 'intelligent stamps,' designed to interact with smartphones using image-recognition technology. The Royal Mail's latest special-issue stamps, devoted to historic British railways, are designed to launch specially developed online content when a user snaps them using an image-recognition application available on iPhone or Android handsets. 'This is the first time a national postal service has used this kind of technology on their stamps and we're very excited to be bringing intelligent stamps to the nation's post,' a Royal Mail spokesman said in a statement. 'Intelligent stamps mark the next step in the evolution of our stamps, bringing them firmly into the 21st century.'"

ACTA Text Leaks; US Caves On ISPs, Seeks Super-DMCA

An anonymous reader writes "Given the history of ACTA leaks, to no one's surprise, the latest
version of the draft agreement (PDF) was leaked last night on KEI's
website. The new version — which reflects changes made during an intense week of negotiations
last month in Washington — shows a draft agreement that is much closer
to becoming reality. Perhaps the most
important story of the latest draft is how the
countries are close to agreement on the Internet enforcement
chapter. In
the face of opposition, the US has dropped its demands on secondary
liability for ISPs but is still holding out hope of establishing a
super-DMCA with digital lock
rules that go beyond the WIPO Internet treaties and were even rejected
by US courts."
