Does Anyone Make a Photo De-Duplicator For Linux? Something That Reads EXIF? 243

postbigbang writes "Imagine having thousands of images on disparate machines. many are dupes, even among the disparate machines. It's impossible to delete all the dupes manually and create a singular, accurate photo image base? Is there an app out there that can scan a file system, perhaps a target sub-folder system, and suck in the images-- WITHOUT creating duplicates? Perhaps by reading EXIF info or hashes? I have eleven file systems saved, and the task of eliminating dupes seems impossible."

Ask Slashdot: It's 2014 -- Which New Technologies Should I Learn? 387

An anonymous reader writes "I've been a software engineer for about 15 years, most of which I spent working on embedded systems (small custom systems running Linux), developing in C. However, web and mobile technologies seem to be taking over the world, and while I acknowledge that C isn't going away anytime soon, many job offers (at least those that seem interesting and in small companies) are asking for knowledge on these new technologies (web/mobile). Plus, I'm interested in them anyway. Unfortunately, there are so many of those new technologies that it's difficult to figure out what would be the best use of my time. Which ones would you recommend? What would be the smallest set of 'new technologies' one should know to be employable in web/mobile these days?"

Submission + - CERN antimatter experiment produces first beam of antihydrogen (web.cern.ch)

An anonymous reader writes: "Matter and antimatter annihilate immediately when they meet, so aside from creating antihydrogen, one of the key challenges for physicists is to keep antiatoms away from ordinary matter. To do so, experiments take advantage of antihydrogen’s magnetic properties (which are similar to hydrogen’s) and use very strong non-uniform magnetic fields to trap antiatoms long enough to study them. However, the strong magnetic field gradients degrade the spectroscopic properties of the (anti)atoms. To allow for clean high-resolution spectroscopy, the ASACUSA collaboration developed an innovative set-up to transfer antihydrogen atoms to a region where they can be studied in flight, far from the strong magnetic field."

Submission + - Physicists explain 'gravity-defying' chain trick (nature.com)

ananyo writes: Leaping up out of a jar in an arc before falling to the floor, the fountain-like motion of a chain of beads has puzzled millions around the world with its apparently gravity-defying behaviour. Now physicists think they have an explanation.
British science presenter Steve Mould, who made the experiment famous, explained the phenomenon as simply one of inertia: the falling chain has downward momentum, causing an upward momentum in beads leaving the pot. This, in turn, makes them leap before gravity can slowly reverse their momentum.
Mould’s explanation was clever, but wrong, says physicist John Biggins of the University of Cambridge, UK. The only way to account for the rise is for the chain to receive a 'kick' from the pot from which it is being pulled. This challenges not only the explanation given by Mould, but the conventional mathematics of chains, Biggins says.

Submission + - Request for Funding OpenBSD HQ's Electricity

An anonymous reader writes: The OpenBSD Project started a Request for Funding our Electricity. As Undeadly.org writes:

OpenBSD supports a wide range of hardware architectures, and for practical and logistical reasons there are few places in the world that have them all in one place except OpenBSD headquarters [...] But keeping all this hardware running involves a considerable electricity bill, and Theo de Raadt (deraadt@) is asking for help, preferably in the form of a company willing to specifically sponsor the project's electricity bill.

Donations are greatly appreciated and bigger donations can go to the OpenBSD Foundation which will help with details and can provide receipts.

James Gosling Grades Oracle's Handling of Sun's Tech 223

snydeq writes "With the four-year anniversary of Oracle's Sun Microsystems acquisition looming, InfoWorld reached out to Java founder James Gosling to rate how Oracle has done in shepherding Sun technology. Gosling gives Oracle eyebrow-raising grades, lauding Oracle's handling of Java, despite his past acrimony toward Oracle over Java (remember those T-shirts?), and giving Oracle a flat-out failing grade on what has become of Solaris OS."

Panoramic Picture Taken By China's Moon Lander 125

Taco Cowboy writes "Perhaps it's not much, but China has released a panoramic view of the moonscape where their lander has landed. They 'stitched' up some 60 photos taken by 3 cameras on the Chang'e 3 lander, taken from 3 different angles — Vertical, 15 degrees up, and 15 degrees down. From the picture, there is a significant sized crater is seen, several meters wide, off to the left of Yutu, the (jade rabbit) moon rover, and located only about 10 meters away from the Chang'e-3 lander."

Submission + - Sweden is closing many prisons due to lack of prisoners. (rtoz.org)

rtoz writes: Sweden is taking steps to close many prisons due to lack of prisoners.

This year alone, four prisons and a detention center got closed in Sweden.

The percentage of the population in Sweden prison is significantly lower than in most other countries.

And,the Swedish prison system is not generally severe. For example, the top-of-the-line prison in Sollentuna, Sweden includes cells with comfortable mattresses and private bathrooms. After prisoners hit the weight room, they can cook up a meal in the state of the art kitchen before kicking back and watching TV on the couch. Sweden’s prison authorities are quick to point out that every square inch of the prison can be seen on a security camera.

Though the Sweden Government is taking steps to close the prisons, crime rate in sweden is not reduced. Actually Crime rate it getting increased in Sweden. It seems they are planning to take steps for preventing the crimes than focusing on sentencing the people involve in criminal activities.

Saturn In All Its Glory 75

The Bad Astronomer writes "On Oct. 10, 2013, the Cassini spacecraft took a series of wide-angle pictures of Saturn from well above the plane of the rings. Croatian software developer and amateur astronomical image processor Gordan Ugarkovic assembled them into a stunning mosaic (mirrored on Flickr), showing the planet from a high angle not usually seen. There's a lot to see in this image, including the rings (and the gaps therein), moons, and the planet itself, including the remnants of a monstrous northern hemisphere storm that kicked off in 2010. It's truly wondrous."

Come Try Out Slashdot's New Design (In Beta) 1191

Slashdot's biggest redesign effort ever is now in beta and you're invited to help guide it. This redesign has been shaped by feedback from community members over the past few months (a big thanks to those of you who participated in our alpha testing phase!), and we'd like your thoughts on it, too. This new design is meant to be richer but also simpler to use, while maintaining the spirit of what Slashdot is all about: News for Nerds. Stuff that matters. Read on for the details of what's included, or read this blog post. Update: 10/02 19:16 GMT by T : Since this post went live, we've been reading through the comments below as well as your (hundreds!) of emails. These are all valuable, as we continue to implement our current features into the Beta. Keep 'em coming; we love the feedback. Please keep in mind that this is called Beta for a reason; we've still folding in lots of improvements. One important thing to bear in mind is that the images are optional: check out the Classic mode by clicking on the view selection widget (just above the stories) on the Beta page.

Are the NIST Standard Elliptic Curves Back-doored? 366

IamTheRealMike writes "In the wake of Bruce Schneier's statements that he no longer trusts the constants selected for elliptic curve cryptography, people have started trying to reproduce the process that led to those constants being selected ... and found it cannot be done. As background, the most basic standard elliptic curves used for digital signatures and other cryptography are called the SEC random curves (SEC is 'Standards for Efficient Cryptography'), a good example being secp256r1. The random numbers in these curve parameters were supposed to be selected via a "verifiably random" process (output of SHA1 on some seed), which is a reasonable way to obtain a nothing up my sleeve number if the input to the hash function is trustworthy, like a small counter or the digits of PI. Unfortunately it turns out the actual inputs used were opaque 256 bit numbers, chosen ad-hoc with no justifications provided. Worse, the curve parameters for SEC were generated by head of elliptic curve research at the NSA — opening the possibility that they were found via a brute force search for a publicly unknown class of weak curves. Although no attack against the selected values are currently known, it's common practice to never use unexplainable magic numbers in cryptography standards, especially when those numbers are being chosen by intelligence agencies. Now that the world received strong confirmation that the much more obscure and less widely used standard Dual_EC_DRBG was in fact an NSA undercover operation, NIST re-opened the confirmed-bad standards for public comment. Unless NIST/the NSA can explain why the random curve seed values are trustworthy, it might be time to re-evaluate all NIST based elliptic curve crypto in general."

Russia Issues Travel Warning To Its Citizens About United States and Extradition 369

mendax writes "The New York Times reports that the Russian government is warning its citizens to not travel to countries that have an extradition treaty with the United States, noting that 'detentions of Russian citizens in various countries, at the request of American law enforcement, have become more frequent.' The article reports the Russian foreign ministry as saying,'Experience shows that the judicial proceedings against those who were in fact kidnapped and taken to the U.S. are of a biased character, based on shaky evidence, and clearly tilted toward conviction.'"
