Comment digiKam is what you want. (Score 2) 243

DigiKam will do everything you want. It works by creating hashes. You set your level of similarity and digiKam will find the files. It can handle multiple locations, and even "albums" on removable media. If you have a lot of images it can be slow, but if you limit any particular search you can greatly improve performance. It is available for Linux and Windows both.

Submission + - New Real Life Laser-Rifle Cuts Through Metal Like A Blowtorch (gizmodo.com)

dryriver writes: We've seen real laser guns before, pulling off tricks like starting small fires, or popping black balloons. That's cool, sure, but it's got nothing—and I mean nothing—on this crazy handheld laser rifle that eats metal for breakfast. Developed by TWI this laser-cutter was initially designed for use by robots, but a few recent tweaks including a pistol-grip and a trigger made it into a human-sized rifle that spits invisible fire like some crazy laser dragon. The rifle is designed specifically with nuclear decommission in mind, specifically chopping up huge pieces of metal infrastructure into bite-sized bits are easily disposed of. And while it's definitely suited for that, it has some short-comings compared typical rifles. That range is pretty low, for instance. And it's not exactly mobile. Also it requires quite the get-up. But damn is it incredible to watch.

Nothing to see here -- keep moving.

Seriously, the costs of the "specially treated glass" will probably exceed the costs of most of the alternatives. And what kind of a usable life can we hope to get from this? Will we have to clean it and recoat it every month?

An interesting academic exercise, but not much more. Let's try news on something practical.

Submission + - Vaccine developed against Ebola (bbc.co.uk)

Lurching writes: Scientists have developed a vaccine that protects mice against a deadly form of the Ebola virus.

First identified in 1976, Ebola fever kills more than 90% of the people it infects.

The researchers say that this is the first Ebola vaccine to remain viable long-term and can therefore be successfully stockpiled.

The results are reported in the journal Proceedings of National Academy of Sciences.

Submission + - Reverse Robocall Turns Tables On Politicians (itworld.com) 2

jfruhlinger writes: "One of the great banes of election season is that any politician can shell out a few pennies per voter and phone-spam thousands of people who'd rather not hear a recorded pitch. But turnabout's fair play, and now a service called reverse robocall will deliver your recorded message to elected officials as often as you'd like for a nominal fee. If you got someone who you'd like to call repeatedly, check them out."

Submission + - Gas Powered Fuel Cell To Fix Electric-Car Range An (greencarreports.com)

thecarchik writes: While electric-car advocates may avoid the issue, some buyers simply won't choose a plug-in car that can't travel unlimited distances. That's where the Chevy Volt-style range extender comes in, though the Volt adds unlimited range by burning gasoline in a conventional engine to generate electric power.

Now a new type of fuel cell offers the potential for a different kind of range extender, one that removes the enormous practical problem facing hydrogen fuel cells: the lack of a distribution infrastructure to fuel vehicles that require pure hydrogen to feed their fuel cells.
Researchers at the University of Maryland have managed to shrink the size and lower the operating temperature of a solid-oxide fuel cell by a factor of 10, meaning it could conceivably produce as much power as a car engine but occupy less space.

The advances come from new materials for the solid electrolyte, as well as design changes, and the researchers feel they have further avenues for improvement left to explore.

ananyo writes: Nano-sized flakes of graphene oxide can be spun into graphene fibres several metres long, researchers in China have shown. The strong, flexible fibres, which can be tied in knots or woven into conductive mats, could be the key to deploying graphene in real-world devices such as flexible batteries.

Comment Missing info (Score 1) 3

Some critical data is missing from this "report".

Salaries stated for Government workers do NOT include their retirement, medical, etc. costs. What a contractor charges does include those costs for their people. Including those costs will make the comparison more equitable, if not tip it the other way.

Doing business with the Federal Government is expensive for a company just because of the amount of paperwork and tracking that is required. Those costs are not part of the internal Federal IT costs.

A very small percentage of federal contractors work in Government facilities. Those that do get charged for at a considerably lower rate than those that work in contractor facilities. All of the facility, training, retirement, etc. costs cited are overhead - added as a percentage of the direct contract costs. Federal contractors go through incredible machinations to cut those overhead costs. They are a major component of a competitive bid, and you can easily lose a bid if they are higher than your competitor.

Government IT can often be cheaper than contractor, but not always, and Government personnel regulations and processes can make hiring new IT personnel a year-long (or more) nightmare. Personnel limits imposed by Congress, whether designed to cut Federal numbers or to benefit contractors, can also make an agency or department go outside for IT support.

The full reasons and costs are NOT easy to tease out, and a simple analysis does NOT get you the real reasons/problems, nor does it provide for valid fixes.

Does Famous Exoplanet 'Fomalhaut b' Really Exist? 40

astroengine writes "The first exoplanet ever to be directly imaged by the Hubble space telescope may not exist. In 2008, the world was in awe of the famous 'Eye of Sauron' image of the star Fomalhaut's dusty ring — plus a slowly moving object that was identified as Fomalhaut b, a gas giant world approximately three times the mass of Jupiter. However, due to a strange orbital misstep detected between 2008 and 2009 photographs, the validity of Fomalhaut b's detection is being questioned, generating some controversy in the exoplanet community."

SCADA Problems Too Big To Call 'Bugs,' Says DHS 92

chicksdaddy writes "With the one year anniversary of Stuxnet upon us, a senior cybersecurity official at the Department of Homeland Security says the agency is reevaluating whether it makes sense to warn the public about all of the security failings of industrial control system (ICS) and SCADA software used to control the U.S.'s critical infrastructure. DHS says it is rethinking the conditions under which it will use security advisories from ICS-CERT to warn the public about security issues in ICS products. The changes could recast certain kinds of vulnerabilities as 'design issues' rather than a security holes. No surprise: independent ICS experts like Ralph Langner worry that DHS is ducking responsibility for forcing changes that will secure the software used to run the nation's critical infrastructure. 'This radically cuts the amount of vulnerabilities in the ICS space by roughly 90%, since the vast majority of security "issues" we have are not bugs, but design flaws,' Langner writes on his blog. 'So today everybody has gotten much more secure because so many vulnerabilities just disappeared.'"

Submission + - Full Duplex Wireless Tech Could Double Bandwidth (computerworld.com)

CWmike writes: "Rice University researchers announced on Tuesday that they have successfully demonstrated full-duplex wireless tech that would allow a doubling of network traffic without the need for more cell towers. Professor Ahutosh Sabharwal said the innovative technology requires a minimal amount of new hardware for both mobile devices and networks. However, it does require new standards, meaning it might not be available for several years as carriers move to 5G networks, he added. By allowing a cell phone or other wireless device to transmit data and receive data on the same frequency, unlike with today's tech, the new standard could double a network's capacity. Rice has created a Wireless Open-Access Research Platform (WARP) with open source software that provides a space for researches from other organizations to innovate freely and examine full-duplex innovations."

Is this the last gasp for SCO or will they try to appeal this to the Supreme Court? The betting lines open at 11...
