Modeling Color Spaces With Blender 35

Posted by samzenpus
from the how-its-done dept.
Mrs. Grundy writes "When creative professionals want to visualize colors in three dimensions, they often use dedicated and sometimes expensive software. Photographer Mark Meyer shows how, with the help of its Python scripting interface, you can create graphics of color models in Blender. He demonstrates plotting in XYZ, LAB, and xyY space, and also includes the Blender file to show how it's done."

Pwnie Express Releases Pwn Pad Ahead of Schedule 24

Posted by samzenpus
from the get-it-early dept.
An anonymous reader writes "The team at Pwnie Express released their Pwn Plug, which combined an off the shelf SheevaPlug with a feature packed open source firmware that turned it into an incredibly capable security tool. Then came the Power Pwn, which hid the same type of functionality into what looked like a standard power strip. Today they've launched their latest product, continuing along the same line of hiding cutting edge open source security tools in plain sight: the Pwn Pad."

from the new-stuff-is-new dept.
adeelarshad82 writes "It's been leaked, teased, accused of being a copy of its predecessor, and celebrated as the likely champion of the mobile ecosystem for 2013. Samsung has finally unveiled the next in their line of globally available smartphones, the Galaxy S4. The phone carries a 5-inch Super AMOLED display with 1080p resolution at 441ppi, weighs only 130 grams and is no more than 7.9mm thick. On the inside, the Exynos based Octo-Core processor clocked at 1.6 GHz and the Snapdragon based Quad-Core 1.9GHz processor power this machine. Galaxy S4 is also packing 2GB of RAM and a 2600mAh battery, and its microSD slot is accessible though the removable rear panel. The S4 will include several new features, such as Air Gesture, Smart Pause, and Smart Scroll. Samsung's vice president of portfolio planning said many of the software improvements in the Samsung Galaxy S4 could make their way into existing Samsung Galaxy S3 phones."

Ask Slashdot: Best Way To Block Noise In a Dorm? 561

Posted by samzenpus
from the keep-it-down dept.
First time accepted submitter zmitch32 writes "I live in a dorm, and I have ADHD, so every little noise distracts me. I know this annoyance isn't limited to those with ADHD, so how does everyone else block out the noise? I can't really cover my walls in soundproof foam because I live in a dorm. I can't just listen to music because I find it too interesting and just end up getting distracted by it. I use ear plugs to block out small noises, but they don't block out human voices very well at all. What do you guys/gals recommend?"

US Cyber Command Discloses Offensive Cyberwarfare Capabilities 136

Posted by samzenpus
from the decker-brigade dept.
MojoKid writes "Earlier this week, the newly minted head of the United States' Cyber Command team and NSA head General Keith Alexander told assembled lawmakers that the U.S. has created an offensive cyberwarfare division designed to do far more than protect U.S. assets from foreign attacks. This is a major change in policy from previous public statements — in the past, the U.S. has publicly focused on defensive actions and homegrown security improvements. General Alexander told the House Armed Services Committee, 'This is an offensive team that the Defense Department would use to defend the nation if it were attacked in cyberspace. Thirteen of the teams that we're creating are for that mission alone.' This is an interesting shift in U.S. doctrine and raises questions like: What's proportional response to China probing at utility companies? Who ought to be blamed for Red October? What's the equivalent of a warning shot in cyberspace? When we detect foreign governments probing at virtual borders, who handles the diplomatic fallout as opposed to the silent retribution?"

Jacob Appelbaum on How OSS Improves Cryptography 35

Posted by timothy
from the dangerous-most-dangerous dept.
destinyland writes "Jacob Appelbaum, the Tor Project's main advocate, argues that Open Source software is necessary 'to both verify and improve' available cryptography. (Adding 'We also need that to ensure that everyone has a reasonable baseline — which is part of the cypherpunk ethos.') In this new interview, he's critical of a general public silence over government encroachments on privacy, but points to the current impact of the Tor network now as something that 'runs, is open and is supported by a large community spread across all walks of life.' And he ultimately identifies Tor as 'part of an ecosystem of software that helps people regain and reclaim their autonomy,' saying the distributed anonymous network 'helps to enable people to have agency of all kinds; it helps others to help each other and it helps you to help yourself.'"

Too Much Gold Delays World's Fastest Supercomputer 111

Posted by timothy
from the other-people's-problems dept.
Nerval's Lobster writes "The fastest supercomputer in the world, Oak Ridge National Laboratory's 'Titan,' has been delayed because an excess of gold on its motherboard connectors has prevented it from working properly. Titan was originally turned on last October and climbed to the top of the Top500 list of the fastest supercomputers shortly thereafter. Problems with Titan were first discovered in February, when the supercomputer just missed its stability requirement. At that time, the problems with the connectors were isolated as the culprit, and ORNL decided to take some of Titan's 200 cabinets offline and ship their motherboards back to the manufacturer, Cray, for repairs. The connectors affected the ability of the GPUs in the system to talk to the main processors. Oak Ridge Today's John Huotari noted the problem was due to too much gold mixed in with the solder."

The Internet's Bad Neighborhoods 77

Posted by timothy
from the wrong-crowd dept.
An anonymous reader writes "Of the 42,000 Internet Service Providers (ISPs) surveyed, just 20 were found to be responsible for nearly half of all the spamming IP addresses — and some ISPs have more than 60% of compromised hosts, mostly in Asia. Phishing Bad Neighborhoods, on the other hand, are mostly in the U.S. Also, there is a silent ticking 'spam' bomb in BRIC countries: if India would have the same Internet penetration rate as the United States while keeping its current ratio of malicious IP addresses, we would observe 200% more spamming IP addresses worldwide. These are just few of the striking results of an extensive study from the University of Twente, in The Netherlands, which scrutinizes the Internet Bad Neighborhoods to develop next-generation algorithms and solutions to better secure networks."

An anonymous reader writes "After running uninterrupted for 3737 days, this humble Sun 280R server running Solaris 9 was shut down. At the time of making the video it was idle, the last service it had was removed sometime last year. A tribute video was made with some feelings about Sun, Solaris, the walk to the data center and freeing a machine from internet-slavery."

Take Hands-Free 360 Degree Panoramic Photos With an iPhone (Video) 109

Posted by Roblimo
from the round-and-round-she-goes-where-she-stops-nobody-knows dept.
In a way, this app is nothing but a cute gimmick. There are many apps that allow you to make panoramic photos on an iPhone, not to mention the panorama feature built into iOS6 -- and plenty for Android, too. But Cycloramic makes your iPhone spin around while standing on edge (on a smooth surface), which is a fine stunt and a great party trick. And it's endorsed by Steve Wozniak, which is a boast few iPhone apps can make. He calls it "Unexpected, fanciful, and useful all at the same time!" Even if it had no practical value whatsoever, you might want to blow 99 cents on Cyclorama just to watch your phone make you dizzy. Most Android phones won't stand on edge. (Tim's won't and neither will mine.) So an Android version would require a stand. Or at least a pattern so we could make our own stands out of cardboard or sheet plastic. But that's a "maybe," and apparently not likely to come along soon. For the moment we'll just have to envy iPhone owners as their phones magically spin around, taking photos now and then as they turn.

Cryptographers Break Commonly Used RC4 Cipher 90

Posted by timothy
from the do-it-one-nanotimes dept.
Sparrowvsrevolution writes "At the Fast Software Encryption conference in Singapore earlier this week, University of Illinois at Chicago Professor Dan Bernstein presented a method for breaking TLS and SSL web encryption when it's combined with the popular stream cipher RC4 invented by Ron Rivest in 1987. Bernstein demonstrated that when the same message is encrypted enough times--about a billion--comparing the ciphertext can allow the message to be deciphered. While that sounds impractical, Bernstein argued it can be achieved with a compromised website, a malicious ad or a hijacked router." RC4 may be long in the tooth, but it remains very widely used.

Adobe Shuts Down Browser Testing Service BrowserLab 40

from the buy-laptops-and-racks dept.
An anonymous reader writes "Adobe has shut down its BrowserLab service, used by many for testing content across multiple desktop platforms. The company pointed its customers to two alternatives: BrowserStack and Sauce Labs. BrowserLab offered cross-browser testing by producing screenshots of websites from various browsers across Windows and OS X platforms. It was very useful for developers looking to support as many different users as possible."

UK Serious Fraud Office Probes Autonomy With ... Autonomy! 34

Posted by timothy
from the audacity-of-autonomy dept.
judgecorp writes "The British Serious Fraud Office (SFO) is investigating whether British software firm Autonomy fiddled its accounts to inflate the price which HP paid for it to a whopping $10 billion. There's a problem though. Autonomy's Introspect software is used to trawl large data sets for information and is in use at the SFO for jobs such as this fraud investigation. It's not just ironic: the SFO says its £4.6 million contract with Autonomy could create a conflict of interest and it may have to pull out of the investigation."

Ask Slashdot: How Do You Stay Fit At Work? 635

Posted by timothy
from the hop-all-the-way-to-the-fridge dept.
Dishwasha writes "What do you do to stay fit? Probably like many of you, this code monkey has lead a fairly sedentary life consisting most on fritos, tab, and mountain dew. Every time I attempt to incorporate exercise in even the most modest amount it never really seems to work out. 'Just do it' or joining and going to a gym just doesn't seem to work and with time being my most precious resource at this point, I would like to incorporate exercise in to my daily work process. Our office recently switched to standing desks, which is great, and I would like to possibly bring in a flat treadmill that fits under the standing desk, but my bosses have balked unless the equipment is whisper silent. We are a small business in a traditional office park with no exercise facility. Do any other geeks out there have a similar set up and would like to share what they use to stay heart healthy and improve circulation during their work day? What other ways do you incorporate exercise in to your geeky or nerdy lifestyle?"
