+ - 229 Ask Slashdot: How to catch Photoshop plagiarism 4

Submitted by jemenake
jemenake (595948) writes "A friend of mine teaches electronic media (Photoshop, Premiere, etc.) at a local high-school. Right now, they're doing Photoshop, and each chapter in the book starts with an "end result" file which shows what they're going to construct in that chapter, and then, given the basic graphical assets (background textures, photos, etc.), the students need to duplicate the same look in the final-result file.

The problem, of course, is that some students just grab the final-result file and rename it and turn it in. Some are a little less brazen and they rename a few layers, maybe alter the colors on a few images, etc. So, it becomes time-consuming for her to open each file alongside the final-result file to see if it's "too perfect".

When I first discovered that she was doing this, my first reaction was that there's got to be some automated way of catching the cheaters. Of course, my first idea of just doing MD5 hashes of each file won't work, since most kids alter the file a little bit.

A second idea I had was to alter the final-result file in a way that isn't obvious, like removing someone's shoelace, mis-spelling a word in the background, or removing/adding some dust-specks. (I know map publishers and music transcribers use this trick to catch copiers). But this still requires that she look for the alteration in each file. I'd think that Photoshop, after all these years, would have some kind of scripting language which also supports some digital watermarking, but I've just never dabbled in that realm.

And, of course, I guess another solution would be for her to not provide the end-result file in Photoshop format, but to export it as a flat image. But I'm still intrigued by the notion of being able to "fuzzily" compare two photoshop files or images to find the ones which are too similar in certain aspects (color histograms, where the edges are, level of noise, whatever).

Anybody else have any clever ideas for this?"

Submitted by
Nerval's Lobster
Nerval's Lobster writes "Google is following up last month’s Samsung Chromebooks with a new, lower-priced one developed by Acer. Retailing for $199, the 11.6-inch Acer C7 Chromebook features an Intel Celeron 847 processor, 2GB of DDR3 memory, a 320GB hard drive, three USB 2.0 ports and an HDMI port for various cords and auxiliary devices. It’s designed for portability, weighing 3.05 pounds and measuring an inch thick. Boot time is reportedly less than 18 seconds.

If the new Chromebook has a weakness, it’s the advertised 3.5 hours of battery life. That’s less than the MacBook Air (which features anywhere from 5-7 hours’ battery life, depending on specs) and many of the Windows-backed Ultrabooks, some of which claim up to 11 hours of battery life depending on usage. It’s also far less than the posted battery life for tablets such as Apple’s iPad and Google’s Nexus 7, which are widely viewed as the most prominent competition to laptops in the extra-portable category."

He costs just $25,000 and works for what amounts to $4 an hour.

Baxter is a step forward in robotics with mass potential. It has a face and sensors to tell it when people are near. It's about as close to a humanoid robot as we can get, and Brooks said it's just the beginning.

"Within 10 years, we're going to see humanoid robots," said Brooks, who was a co-founder of iRobot, maker of iRoomba, the vacuum cleaner robot."

The document, uncovered by Maurizio Morabito, puts comments by the BBC that the meeting was held under Chatham House rules, and that that the seminar drew on top scientific advice in an interesting light. In a bizarre co-incidence, four of the BBC's attendees at the seminar have resigned in the last few days."

Submitted by
ananyo
ananyo writes "Many people dislike the clashing dissonances of modernist composers such as Arnold Schoenberg. But what’s our problem with dissonance?
There has long been thought to be a physiological reason why at least some kinds of dissonance sound jarring. Two tones close in frequency interfere to produce 'beating': what we hear is just a single tone rising and falling in loudness. If the difference in frequency is within a certain range, rapid beats create a rattling sound called roughness. An aversion to roughness has seemed consistent with the common dislike of intervals such as minor seconds.
Yet when cognitive neuroscientist Marion Cousineau of the University of Montreal in Quebec and her colleagues asked amusic subjects (who cannot distinguish between different musical tones). to rate the pleasantness of a whole series of intervals, they showed no distinctions between any of the intervals but disliked beating as much as people with normal hearing.
Instead the researchers propose that harmonicity is the key. Notes contain many overtones — frequencies that are whole-number multiples of the basic frequency in the note. For consonant 'pleasant sounding' intervals the overtones of the two notes tend to coincide as whole-number multiples, whereas for dissonant intervals this is no longer the case.
The work suggests that harmonicity is more important than beating for dissonance aversion in normal hearers (abstract)."

Microsoft

+ - 126 Windows Head Leaves Microsoft

Submitted by
Hugh Pickens writes
Hugh Pickens writes writes "The Guardian reports that in a shocking move move that comes just two weeks after the launch of Windows 8, Steven Sinofsky, the head of the Windows division at Microsoft is to leave the company. Sinofsky had been at the company for 23 years and had been seen by some as a future chief executive of the software giant but according to reports, there had been growing executive friction between Sinofsky and other top executives at the company. "This is shocking news. This is very surprising," says Brendan Barnicle, an analyst at Pacific Crest Securities. "Like a lot of people, I thought Sinofsky was in line to potentially be Ballmer's successor." Sinofsky's place will be taken by Julie Larson-Green, another Windows executive who has been at Microsoft nearly as long as Sinofsky – joining in 1993 – and will be in charge of hardware and software for Windows. "If this had happened before Windows 8 shipped, I would have worried about potential delays," says Al Hilwa, program director for application software at the research company IDC. "The strategy of folding PC, tablet, phone and set-top into a single platform and ecosystem is the right strategy, and likely will continue to be the strategy of record.""

Submitted by Artefacto
Artefacto (1207766) writes "The Ksplice team has made available a git repository with the changes Red Hat made to the kernel broken down. They are calling this project RedPatch.

This comes in response to a policy change Red Hat had operated in early 2011 with the goal of undercutting Oracle and other vendor's strategy of poaching RedHat's customers. The Ksplice team says they've doing the work they're now making available since the policy was implemented; they claim to be now making it public because they "feel everyone in the Linux community can benefit from the work".

For Ksplice, we build individual updates for each change and rely on source patches that are broken-out, not a giant tarball. Otherwise, we wouldn’t be able to take the right patches to create individual updates for each fix, and to skip over the noise — like a change that speeds up bootup — which is unnecessary for an already-running system. We’ve been taking the monolithic Red Hat patch tarball and breaking it into smaller commits internally ever since they introduced this change.

At Oracle, we feel everyone in the Linux community can benefit from the work we already do to get our jobs done, so now we’re sharing these broken-out patches publicly.

RockDoctor (15477) writes "A man has been bailed by a New Zealand court for allegedly planning to [...] throw horse manure at [the Prince of Wales and Duchess of Cornwall].

The 76-year-old "known anti-royalist" was ordered to stay at least 500 metres (550 yards) away from the royal couple
(BBC)

Very obviously therefore, the Republican (sense: anti-imperialist, e.g. Brutus Senior or Junior ) campaigner is working out how to throw shit from significantly more than 500m away.
I can think of two [edit : three] credible technologies : a trailer-mounted trebuchet ; a shit-atomiser sited over 500m upwind and producing a miasma blowing downwind ; or a remote-controlled plane fitted with a real-time camera and a shit-dispenser.
Can Slashdot come up with better suggestions for assisting this vital free speech task?

As a corollary, the mechanism for dispensing shit from the model plane needs a name. Preferably a "backronym", such as an "ADAM — Automated Dispenser of Aerial Manure" or a JAMIE ... which I can't think of anything for. (Yes, those names are suggested by the Mythbusters and their "shit hits the fan" experiments.)"

Security experts have identified thousands of resulting Stuxnet infections. On Monday, multinational energy giant Chevron became the first U.S. company to admit that it, too, was infected by Stuxnet.

"'Escaped' continues to be a puzzling term when applied to a virus that relied on numerous Microsoft zero-day vulnerabilities and propagation vectors," said Sean McBride, the director of analysis for Critical Intelligence, in a SANS newsletter. "On the other hand, if your system was not the single underground facility in Iran that Stuxnet was intended to disrupt, the infection was benign. Such collateral damage is part of the price industry gets to pay for — what was then — two more years of Iran [being] without a nuclear weapon.""

His last post, fittingly, was entitled 'Updating Windows 8 for General Availability.' The OS was officially launched at the end of last month. According to the All Things D blog, there was growing tension between Sinofsky and other members of the Microsoft executive team, who didn't see him as enough of a team player. But Microsoft's official position is that the decision was a mutual one. Sinofsky had only good things to say about his former employer."
