How Generation Y really feels about online privacy | CNET Blog | Digital Media Literacy + Cyber Arts + Performance Centers Connected to Fiber Networks | Scoop.it

A group of consumer panelists shared their candid thoughts on online privacy during a tell-all panel discussion on Generation Y and digital media at CES.

 

Six extremely articulate young adults ages 18 to 28 fielded questions from moderator Xavier Kochhar and the audience about their social media preferences and attitudes. On the topic of privacy, Darius, a 22-year-old fashion designer who uses Twitter "for therapy" summed up the group's attitude with this statement: "We live in public."

 

Darius was keenly aware that everything he shares on Twitter or other social media platforms is "out there," which has made him extremely conscious about what he posts. "I would expect people to be more conscious," he said.

 

The other panelists shared Darius' view and discussed the ways in which they went about keeping their content private. Jordan, a 20-year-old student and environmentalist, said she changed her Facebook settings specifically because of how the social network handles tagging. "I have to filter myself," she said, explaining that she was concerned that some photos or check-ins she was tagged in on Facebook would send the wrong message to employers and colleagues.

The Guggenheim Puts 109 Free Modern Art Books Online | Open Culture

The Guggenheim Puts 109 Free Modern Art Books Online | Open Culture | Digital Media Literacy + Cyber Arts + Performance Centers Connected to Fiber Networks | Scoop.it

Back in January, 2012, we mentioned that the Guggenheim (the Frank Lloyd Wright-designed modern art museum in NYC) had put 65 art catalogues on the web, all free of charge.

We’re happy to report that, between then and now, the number of free texts has grown to 109. Published between 1937 and 1999, the art books/catalogues offer an intellectual and visual introduction to the work of Alexander Calder, Edvard Munch, Francis Bacon, Gustav Klimt & Egon Schiele, Fernand Léger, and Kandinsky. Plus there are other texts (e.g., Masterpieces of Modern Art and Abstract Expressionists Imagists) that tackle meta movements and themes.

Anyone interested in the history of the Guggenheim will want to spend time with a collection called “The Syllabus.” It contains five books by Hilla Rebay, the museum’s first director and curator. Together, they let you take a close look at the art originally housed in the Guggenheim when the museum first opened its doors in 1939.

Sun Ra’s Full Lecture & Reading List From His 1971 UC Berkeley Course, “The Black Man in the Cosmos” | Open Culture

Sun Ra’s Full Lecture & Reading List From His 1971 UC Berkeley Course, “The Black Man in the Cosmos” | Open Culture | Digital Media Literacy + Cyber Arts + Performance Centers Connected to Fiber Networks | Scoop.it

A pioneer of “Afrofuturism,” bandleader Sun Ra emerged from a traditional swing scene in Alabama, touring the country in his teens as a member of his high school biology teacher’s big band. While attending Alabama Agricultural and Mechanical University, he had a out-of-body experience during which he was transported into outer space.


As biographer John Szwed records him saying, “my whole body changed into something else. I landed on a planet that I identified as Saturn.” While there, aliens with “little antenna on each ear. A little antenna on each eye” instructed him to drop out of college and speak through his music. And that’s just what he did, changing his name from Herman Blount and never looking back.

Whether you believe that story, whether Sun Ra believes it, or whether his entire persona is a theatrical put-on should make no difference. Because Sun Ra would be a visionary either way.


Combining Afrocentric science fiction, esoteric and occult philosophy, Egyptology, and, with his “Arkestra,” his own brand of free jazz-futurism that has no equal on earth, the man is truly sui generis. In 1971, he served as artist-in-residence at UC Berkeley and offered a spring semester lecture, African-American Studies 198, also known as “Sun Ra 171,” “The Black Man in the Universe,” or “The Black man in the Cosmos.”


The course featured readings from—to name just a few—theosophist Madame Blavatsky, French philosopher Constantin Francois de Chasseboeuf, black American writer and poet Henry Dumas, and “God,” whom the cosmic jazz theorist reportedly listed as the author of The Source Book of Man’s Life and Death (otherwise known as the King James Bible).

NASA sets asteroid mission, demo technologies | Michael Cooney | NetworkWorld.com

NASA sets asteroid mission, demo technologies | Michael Cooney | NetworkWorld.com | Digital Media Literacy + Cyber Arts + Performance Centers Connected to Fiber Networks | Scoop.it

NASA officials today said they have picked the specific asteroid mission and offered new details for that mission which could launch in the 2020 timeframe.

Specifically, NASA’s associate administrator Robert Lightfoot said the Asteroid Redirect Mission (ARM) will rendezvous with the target asteroid, land a robotic spacecraft on the surface, grab a 4 meter or so sized boulder and begin a six-year journey to redirect the boulder into orbit around the moon for exploration by astronauts.

+More on network World: How to protect Earth from asteroid destruction; Quick look: NASA’s ambitious asteroid grabbing mission+

There had been a discussion about grabbing an entire asteroid and bringing it back to Lunar orbit but that proved to be more complicated and costly – about $100 million more than the boulder-grabbing scheme, Lightfoot said.

Lightfoot said NASA has so far identified three valid asteroid candidates for the mission: Itokawa, Bennu and 2008 EV5, though it is focusing on the 2008EV 5 asteroid for now. Lightfoot said EV5 has a number of attractive qualities, namely it not been visited by other spacecraft missions, it has been extensively observed, its orbit is well known and it is a carbonaceous asteroid – the most common type of asteroid and contains a number of elements scientists are interested in studying up close.

DuoPad adds touchscreen-like functionality to existing PCs | Dave LeClair | GizMag.com

DuoPad adds touchscreen-like functionality to existing PCs | Dave LeClair | GizMag.com | Digital Media Literacy + Cyber Arts + Performance Centers Connected to Fiber Networks | Scoop.it

With Windows 8, and continuing into Windows 10, Microsoft has created an OS with a bit more of a touchscreen focus. As a solution, many computer makers are selling laptops and all-in-ones with touchscreens, but what about users who already have a computer? The DuoPad trackpad aims to bring a touchscreen-like feel to PCs in a way that is surprisingly cool.

A standard trackpad would see the user simply moving the mouse pointer around on the screen, but with the DuoPad, the user's hand is captured by a high-resolution IR camera and then an image of it is placed on the screen. From there, users can tap, pinch, swipe, and make other movements that would work on a touchscreen.

Users can adjust the opacity and color of the hand that's shown on the screen, which should allow them to fine-tune the look to meet their needs. They can also darken the outline around the superimposed hand, to make it easier to see when low opacity is selected.

The NASA Gemini program: 50 years on | Anthony Wood | GizMag.com

The NASA Gemini program: 50 years on | Anthony Wood | GizMag.com | Digital Media Literacy + Cyber Arts + Performance Centers Connected to Fiber Networks | Scoop.it

March 23 marked the 50th anniversary of the launch of Gemini III – the first manned mission of the now-legendary Gemini program. Following hot on the heels of the Mercury missions, and only a short time after President Kennedy's famous speech in which he announced his intent to put a man on the Moon by the end of the decade, Gemini was tasked with testing the technologies and techniques that would lead America to victory in the space race.

Whilst the earlier Mercury program was hailed a success, the Russians (then the Soviet Union), had triumphed by putting the cosmonaut Yuri Gagarin in space ahead of the Americans. Temporarily defeated, but not beaten, NASA knew that there were other firsts to achieve – the race to the Moon was on, and national pride was at stake like never before.

To lay the groundwork for an eventual Moon landing, a number of key technologies had to be developed and honed. This was the purpose of Gemini. The program had four primary goals – to test the effects of prolonged exposure to space on a team of two astronauts, to successfully execute rendezvous and docking maneuvers with a second spacecraft in orbit, to perfect re-entry and landing, and finally, to assess the physical and psychological effects of weightlessness and confinement on the crews of the Gemini missions.

The program ran from 1962 to 1966, and saw the launch of two initial uncrewed test missions, seven target vehicles, and 10 crewed missions. The total cost for the Gemini program ran to nearly US$1.3 billion in 1967, which paid for the testing of cutting-edge technologies.

Searching for the origins of life with the James Webb Space Telescope | Dario Broghino | GizMag.com | Digital Media Literacy + Cyber Arts + Performance Centers Connected to Fiber Networks | Scoop.it

Hubble has been a boon to deep space exploration, gifting us iconic pictures of the skies and revealing new insights into the history of the early universe. For the next big step in space astronomy, NASA, ESA and the Canadian Space Agency (CSA) are raising the stakes even higher with one of their most ambitious projects in decades: building the largest space telescope ever ... the James Webb Space Telescope.

The James Webb Space Telescope, JWST for short, will have seven times the light-collecting capability of Hubble, span the size of a tennis court, and be so sensitive it could spot a single firefly a million kilometers away.

This "absolutely impressive piece of engineering," as NASA administrator Charles Bolden put it, includes technologies that make this spacecraft unlike any other and will allow us to learn about Earth-like exoplanets, help us understand how life began on Earth, and image the cosmos as it was only millions of years after the Big Bang, further back in time than ever before.

'Largest ever asteroid impact' found in Australia | BBC News

'Largest ever asteroid impact' found in Australia | BBC News | Digital Media Literacy + Cyber Arts + Performance Centers Connected to Fiber Networks | Scoop.it

The surface crater has long since disappeared from central Australia's Warburton Basin but geophysical modelling below the surface found evidence of two massive impacts, said Dr Andrew Glikson, who led the ANU team.

"It would have been curtains for many life species on the planet at the time," said Dr Glikson.

But the team, which published its findings in the geology journal Tectonophysics, has not been able to connect the impact to any known extinction.

"It's a mystery - we can't find an extinction event that matches these collisions," said Dr Glikson. "I have a suspicion the impact could be older than 300 million years."

Your Face Scares Me: Understanding the Hyperrational Adolescent Brain | Todd Finley Blog | Edutopia.org

Your Face Scares Me: Understanding the Hyperrational Adolescent Brain | Todd Finley Blog | Edutopia.org | Digital Media Literacy + Cyber Arts + Performance Centers Connected to Fiber Networks | Scoop.it

Take off your snarky hat. Adolescents get a bad rap, says Dr. Daniel Siegel, and he should know. He's a clinical professor of psychiatry at the UCLA School of Medicine, founding co-director of the Mindful Awareness Research Center, Distinguished Fellow of the American Psychiatric Association, Executive Director of the American Psychiatric Association, and author of many books, videos, and articles on the mind. Despite his endless awards and titles, Siegel displays in lectures the warm avuncularity of James Taylor in an off-the-rack suit as he urges parents and educators to stop viewing adolescence as a grim and crazed space that kids need to cross through quickly. Why? Because teens will perceive these attitudes and act accordingly.

Siegel’s recent and sobering book, Brainstorm: The Power and Purpose of the Teenage Brain, relies on recent neurobiology research to explain how the mind works during adolescence, the ages between 12 and 24. It's not just adding five years onto a ten-year-old’s brain, he says. Teenagers get a whole new brain. More to the point, his book sensibly frames how adolescents' brain developments and concomitant personality traits serve a grand purpose -- preparation to leave the nest.

According to Siegel, there are several unique features of the adolescent mind that deserve the awareness of teachers who "alloparent" (perform parenting duties without technically being a guardian).

Stellar viewing: The solar eclipse in pictures | Anthony Wood | GizMag.com

Stellar viewing: The solar eclipse in pictures | Anthony Wood | GizMag.com | Digital Media Literacy + Cyber Arts + Performance Centers Connected to Fiber Networks | Scoop.it

Friday morning bore witness to a stunning solar eclipse, as our Moon traversed the face of our parent star, blocking its light in a beautiful example of the intricate orbits negotiated by the planets and moons that make up our solar system. For those able to secure a pair of protective glasses and be charmed enough to gaze through cloud-free skies, the sight was a spectacular one – a rare meeting of two celestial bodies that have accompanied each of us through every day and night of our lives.

Even when direct viewing was made impossible thanks to either a woefully short supply of glasses or a frankly spiteful weather system, hope was not lost. The event was streamed live online via the robotic observatory service Slooh, who carried a webcast of the event from Norweigan Svalbard – a little archipelago far enough North to lie in the zone of totality, and thus see the Moon fully eclipse the Sun.

As the celestial ballet unfolded, ESA minisatellites Proba-2 and Proba-V documented the event from space, capturing images of the eclipse itself, and the resultant shadow cast onto the Earth's surface. This rare view from space was shared by astronauts aboard the ISS, who tweeted some of their favorite snaps of the occasion.

The next total solar eclipse is due to take place in March 2016, however the zone of totality will rarely touch the land, making it a challenging prospect for astronomy enthusiasts hoping to directly view the event. An easier time will be had of it in August 2017, when the zone of totality will run the length of the American mainland.

A replay of the Slooh webcast can be found online.

Why Virtual Reality Is Happening Now | Kyle Russell | TechCrunch.com

Why Virtual Reality Is Happening Now | Kyle Russell | TechCrunch.com | Digital Media Literacy + Cyber Arts + Performance Centers Connected to Fiber Networks | Scoop.it

Since the Oculus Rift first made waves with its successful Kickstarter, there’s been a consistent line of criticism based in the notion, “why would it work this time?”

It’s a fair question — you can go back decades and see myriad failed attempts to build virtual reality gear for the masses.

“Many very smart people have attempted to do this! What didn’t they see that Oculus and its compatriots see today? People didn’t want a Virtual Boy in 1995, why would they buy a Rift in 2015?”

That perspective misses one of the most important (and, almost always, obvious in hindsight) factors in tech: the actual technology that makes up a product.


Take a look at the actual pieces that, when put together in the right way, result in an Oculus headset. You’ve got a high pixel density LCD screen, a gyroscope and camera for positional tracking, and a 3D environment processed in real-time by a desktop computer or (in the case of the Oculus-compatible Gear VR, a phone!).


All of these things are only available at affordable prices to consumers thanks to advancements in other areas that have taken place over decades — specifically, smartphones and video games.


Was it possible for a hardware maker to build a display with a resolution greater than 1080p for a VR headset even ten years ago? Nope — it would have been prohibitively expensive for consumers and would use way too much power for portable devices to be a possibility without obnoxiously large external battery packs.

For instance, let’s say that to get the best experience in VR, your ~5.5-inch screen has to be 4K and refresh 120 times per second. In 2003, a screen with approximately that resolution would have run you $8,400, and would only refresh 12 times per second. Oh yeah, and it used as much power as a small desktop computer.


The current Oculus dev kit uses a 1080p screen from a Samsung Galaxy 3 and can refresh 75 times per second. The Gear VR uses the Galaxy Note 4’s 1440p screen. Progress!

Craig Miller's curator insight, March 26, 9:00 PM

A great article which explains a moore's law like correlation between computing power and virtual reality quality. It explains the trend of virtual reality head sets getting either more powerful each one or two years or the same head set becoming cheaper.  It shows a trend of virtual reality head sets getting better as computers do which could mean we will continue to increase the power of virtual reality over time.

Thomas Blake's curator insight, Today, 1:48 AM

In the past virtual reality has been attempted but never became very popular as it was always lacking in some department, whether it be the 3D effects, computer graphics or display technology. However at this point in time virtual reality is the next step for video games.  We finally have the technology for advanced enough graphics and high pixel density displays for it to be viable to make the virtual reality believable. Such an evolutionary step has not been achieved since the mid 90's when video games switched from using 2D sprites to 3D models.

Massive Underground City Found in Cappadocia Region of Turkey | Jennifer Pinkowski | National Geographic

Massive Underground City Found in Cappadocia Region of Turkey | Jennifer Pinkowski | National Geographic | Digital Media Literacy + Cyber Arts + Performance Centers Connected to Fiber Networks | Scoop.it

When the invaders came, Cappadocians knew where to hide: underground, in one of the 250 subterranean safe havens they had carved from pliable volcanic ash rock called tuff.

Now a housing construction project may have unearthed the biggest hiding place ever found in Cappadocia, a region of central Turkey famous for the otherworldly chimney houses, cave churches, and underground cities its residents carved for millennia.

Discovered beneath a Byzantine-era hilltop castle in Nevşehir, the provincial capital, the site dates back at least to early Byzantine times. It is still largely unexplored, but initial studies suggest its size and features may rival those of Derinkuyu, the largest excavated underground city in Cappadocia, which could house 20,000 people.

In 2013, construction workers demolishing low-income homes ringing the castle discovered entrances to a network of rooms and tunnels. The city halted the housing project, called in archaeologists and geophysicists, and began investigating.


A 300-year-old paper trail between the local government and Ottoman officials suggested where to begin. “We found documents stating that there were close to 30 major water tunnels in this region,” says Nevşehir mayor Hasan Ünver.

In 2014, those tunnels led scientists to discover a multilevel settlement of living spaces, kitchens, wineries, chapels, staircases, and bezirhane—linseed presses for producing lamp oil to light the underground city. Artifacts including grindstones, stone crosses, and ceramics indicate the city was in use from the Byzantine era through the Ottoman conquest.

NASA's Curiosity rover finds nitrogen on Mars | David Szondy | GizMag.com

NASA's Curiosity rover finds nitrogen on Mars | David Szondy | GizMag.com | Digital Media Literacy + Cyber Arts + Performance Centers Connected to Fiber Networks | Scoop.it

In another hopeful sign that Mars was once habitable, NASA's Curiosity rover has detected nitrogen in the soil of the Red Planet for the first time.

NASA says that the nitrogen was detected indirectly in the form of nitric oxide when soil samples were heated using the mass spectrometer and gas chromatograph on Curiosity's Sample Analysis at Mars (SAM) instrument.

The instruments detected various nitrogen compounds, including nitric oxide, which is produced by the breakdown of nitrates, in amounts that indicate that nitrates were a much more probable source than alternatives.

Nitrates (NO3) are nitrogen-bearing molecules containing nitrogen and oxygen that are basic to biology and are found in DNA, proteins, and many other organic molecules.

On Earth, nitrogen is mostly found in the form of nitrogen gas in the atmosphere, but plants and bacteria are able to "fix" the nitrogen molecules into nitrates, so they can be used by other organisms. However, they can also be produced by lightning or, in the case of Mars, carried down by meteorites.

A Loss For Words--Can Dying Languages Be Saved? | Judith Thurman | The New Yorker

A Loss For Words--Can Dying Languages Be Saved? | Judith Thurman | The New Yorker | Digital Media Literacy + Cyber Arts + Performance Centers Connected to Fiber Networks | Scoop.it

It is a singular fate to be the last of one’s kind. That is the fate of the men and women, nearly all of them elderly, who are—like Marie Wilcox, of California; Gyani Maiya Sen, of Nepal; Verdena Parker, of Oregon; and Charlie Mungulda, of Australia—the last known speakers of a language: Wukchumni, Kusunda, Hupa, and Amurdag, respectively. But a few years ago, in Chile, I met Joubert Yanten Gomez, who told me he was “the world’s only speaker of Selk’nam.” He was twenty-one.

Yanten Gomez, who uses the tribal name Keyuk, grew up modestly, in Santiago. His father, Blas Yanten, is a woodworker, and his mother, Ivonne Gomez Castro, practices traditional medicine. As a young girl, she was mocked at school for her mestizo looks, so she hesitated to tell her children—Keyuk and an older sister—about their ancestry. They hadn’t known that their maternal relatives descended from the Selk’nam, a nomadic tribe of unknown origin that settled in Tierra del Fuego. The first Europeans to encounter the Selk’nam, in the sixteenth century, were astonished by their height and their hardiness—they braved the frigid climate by coating their bodies with whale fat. The tribe lived mostly undisturbed until the late eighteen-hundreds, when an influx of sheep ranchers and gold prospectors who coveted their land put bounties on their heads. (One hunter boasted that he had received a pound sterling per corpse, redeemable with a pair of ears.) The survivors of the Selk’nam Genocide, as it is called—a population of about four thousand was reduced to some three hundred—were resettled on reservations run by missionaries. The last known fluent speaker of the language, Angela Loij, a laundress and farmer, died forty years ago.

Many children are natural mimics, but Keyuk could imitate speech like a mynah. His father, who is white, had spent part of his childhood in the Arauco region, which is home to the Mapuche, Chile’s largest native community, and he taught Keyuk their language, Mapudungun. The boy, a bookworm and an A student, easily became fluent. A third-grade research project impassioned him about indigenous peoples, and Ivonne, who descends from a line of shamans, took this as a sign that his ancestors were speaking through him. When she told him of their heritage, Keyuk vowed that he would master Selk’nam and also, eventually, Yagán—the nearly extinct language of a neighboring people in the far south—reckoning that he could pass them down to his children and perhaps reseed the languages among the tribes’ descendants. At fourteen, he travelled with his father to Puerto Williams, a town in Chile’s Antarctic province that calls itself “the world’s southernmost city,” to meet Cristina Calderón, the last native Yagán speaker. She subsequently tutored him by phone.

If it is lonely to be the last of anything, the distinction has a mythic romance: the last emperor, the last of the Just, the last of the Mohicans. Keyuk’s precocity enhanced his mystique. A Chilean television station flew him to Tierra del Fuego as part of a series, “Sons of the Earth,” that focussed on the country’s original inhabitants. He was interviewed, at sixteen, by the Financial Times. A filmmaker who knew him put us in touch, and we met at a café in Santiago.

Alan Lomax's Massive Archive Goes Online | Joel Rose | NPR.org

Alan Lomax's Massive Archive Goes Online | Joel Rose | NPR.org | Digital Media Literacy + Cyber Arts + Performance Centers Connected to Fiber Networks | Scoop.it

Folklorist Alan Lomax spent his career documenting folk music traditions from around the world. Now thousands of the songs and interviews he recorded are available for free online, many for the first time. It's part of what Lomax envisioned for the collection — long before the age of the Internet.

Lomax recorded a staggering amount of folk music. He worked from the 1930s to the '90s, and traveled from the Deep South to the mountains of West Virginia, all the way to Europe, the Caribbean and Asia. When it came time to bring all of those hours of sound into the digital era, the people in charge of the Lomax archive weren't quite sure how to tackle the problem.

"We err on the side of doing the maximum amount possible," says Don Fleming, executive director of the Association for Cultural Equity, the nonprofit organization Lomax founded in New York in the '80s. Fleming and a small staff made up mostly of volunteers have digitized and posted some 17,000 sound recordings.

"For the first time, everything that we've digitized of Alan's field recording trips are online, on our website," says Fleming. "It's every take, all the way through. False takes, interviews, music."

ESO's APEX observations shed light on 17th-century star collision | Chris Wood | GizMag.com

ESO's APEX observations shed light on 17th-century star collision | Chris Wood | GizMag.com | Digital Media Literacy + Cyber Arts + Performance Centers Connected to Fiber Networks | Scoop.it

The European Southern Observatory's (ESO) Atacama Pathfinder Experiment telescope (APEX) has been used to solve a 340 year-old astronomical mystery. The findings reveal that an object that appeared in the sky in the 17th century was not a nova as astronomers at the time believed, but actually a rare stellar collision.

Accounts of the event, where a star suddenly appeared in the sky, have long been of interest to astronomers. Named in part for its year of discovery, Nova Vulpeculae 1670 was easily visible to the naked eye when it first appeared, but its remnants are now so faint that submillimeter observations were required to shed light on the mysterious event.

What has puzzled both modern and historical astronomers about Nova Vul 1670 is the manner of its apparent arrival and subsequent disappearance. According to historical accounts, the object was clearly visible in the night sky for two years after its first appearance, before disappearing and reappearing twice, and then finally vanishing.

While astronomers have studied the patch of sky for centuries, it wasn't until the 1980s that a faint nebula was detected, and even then, available technology wasn't equal to the task of deciphering what had actually been witnessed more than 300 years ago. The new observations finally answer the centuries-old riddle.

Ground was broken at the future six-acre (2.4-hectare) site of the new Space Fence radar system in a special ceremony last month on Kwajalein Atoll in the Marshall Islands. The ceremony marked the official start of construction of the system that will replace the Air Force Space Surveillance System (AFSSS) in tracking objects in orbit, including commercial and military satellites and debris from collisions.

Beating out Raytheon, Lockheed Martin was awarded a US$914,699,474 contract on June 2 of last year by the US Air Force to develop its Space Fence system design and deliver the first site, consisting of a radar and Space Fence operations center. In addition to the radar arrays and on-site operations center, the Kwajalein installation will also include an annex to the island's current power plant to ensure continuous operation.

The new system will replace the AFSSS, which began operations in 1961 and ceased operations in September 2013. It used a VHF radar system capable of detecting objects down to about 75 cm (29.5 in) in size, while the higher wave frequency (or shorter wavelength) of the S-band ground-based radars to be used in the new Space Fence will allow it to detect much smaller objects.

Crypto-ransomware attack encrypts New Jersey school district network | Ms. Smith | NetworkWorld.com

Crypto-ransomware attack encrypts New Jersey school district network | Ms. Smith | NetworkWorld.com | Digital Media Literacy + Cyber Arts + Performance Centers Connected to Fiber Networks | Scoop.it

New Jersey school district Swedesboro-Woolwich is a victim of crypto-ransomware.

When Swedesboro-Woolwich school district, which has four elementary schools with a total of about 2,000 students, was hit with crypto-ransomware, big guns showed up to investigate. After the district's network was locked up due to ransomware on March 22, the local Woolwich Police, the New Jersey State Police Cyber Crimes Unit, the FBI and Homeland Security are all investigating.

In an announcement about the malware, the school district said:

Forensic analysis is being performed by the NJ State police. At this point there appears to be no data breach. The files affected were mainly Word documents, Excel spreadsheets and .pdf files created by staff members. Data for the student information system as well as other applications is [sic] stored offsite on hosted servers and was not affected by the virus.

It's also thrown a kink in the school district's scheduled Partnership for Assessment of Readiness for College and Careers (PARCC) exams, which are "high-quality, computer-based K–12 assessments in Mathematics and English Language Arts/Literacy." The crypto-ransomware "has affected the district's entire operations from internal and external communications to its point-of-sale for school lunches. It also has prevented any students from taking the scheduled PARCC exams, which are entirely computerized."

South Jersey Times first reported that Superintendent Terry Van Zoeren said, "There's basically no tech service happening in Swedesboro-Woolwich right now. Essentially our network has been taken over and has been made nonoperational."

Roger Smith's curator insight, March 25, 5:59 PM

I want to know why these organisations do not have business continuity and disaster recovery that make them cyber resilient.  This comment is absolute bull!


"We are operating as if it's about 1981 again," Van Zoeren said. The network administrator received a message with complex directions to forward $500 in bitcoins -- a digital currency popular on underground online markets."

NASA's Curiosity finds new ingredient of life on Mars | Sharon Gaudin | ComputerWorld.com

NASA's Curiosity finds new ingredient of life on Mars | Sharon Gaudin | ComputerWorld.com | Digital Media Literacy + Cyber Arts + Performance Centers Connected to Fiber Networks | Scoop.it

After already finding evidence of water on Mars, NASA’s Curiosity rover has discovered another key element necessary for life on the Red Planet.

NASA said Tuesday that the robotic rover has, for the first time, detected nitrogen on the Martian surface. The nitrogen – found in the form of nitric oxide – could be released during the natural breakdown of nitrates, which are molecules that contain the type of nitrogen that can be used by living organisms.

The discovery does not mean there is life on Mars.

NASA scientists don't believe the nitrogen discovered was created by life on Mars. The nitrogen is likely ancient and could have been deposited there by meteorite impacts and lightning.

The discovery provides scientists with another piece of the puzzle suggesting that ancient Mars once was capable of supporting life.

The detection of nitrogen is a milestone for Curiosity, which was sent to Mars for the sole purpose of finding out if the planet was ever capable of supporting life, even in microbial form.

The world's best teacher lives in rural Maine and doesn't care about test scores | Lauren Gambino | The Guardian

The world's best teacher lives in rural Maine and doesn't care about test scores | Lauren Gambino | The Guardian | Digital Media Literacy + Cyber Arts + Performance Centers Connected to Fiber Networks | Scoop.it

Ms Atwell’s school in the rural town of Edgecomb, Maine, is no ordinary place of learning. Then again, Nancie Atwell is no ordinary teacher.

At her school, all classrooms have libraries, standardized tests are forbidden, classes are small, every religious and cultural holiday is celebrated, and students pick the topics they write about and the books they read. And read they do: her students wolf down about 40 books per year, well above the national average.

Earlier this month, Atwell was named the winner of a competition to find the world’s best teacher. She accepted the Global Teacher Prize, dubbed the Nobel Prize of teaching, at a ceremony in Dubai.

Atwell chose to dedicate the entire award – $1m worth – to the Center for Teaching and Learning (CTL), the nonprofit demonstration school she founded 25 years ago, which she said is in need of structural upgrades, including a new roof and furnaces, and many more books. “We will have a very healthy book-buying fund,” Atwell told the Guardian. “It’s the thing we never have enough of.”

Atwell’s prolific teaching career spans four decades and several school districts. She is also the author of nine books for teachers, including In the Middle, which sold half a million copies. Her goal, she said, is to make the classroom a place for “wisdom and happiness”, rather than one of stress and frustration.

The world’s top educator, however, said she never intended to become a teacher. Instead, she fell into the position while trying to figure out what to do with an English degree. After graduation, she took a student teaching position as a “fallback plan”.

“I fell in love with teaching,” she said. “I felt like I was home. I love literature and I really loved adolescents, I found out. And to have relationships with kids around books and to talk to kids about books seemed like the best gig in the world.”

Prehistoric hunt suggests humans arrived in North America earlier than previously thought | Laura Santhanam | PBS News Hour

Prehistoric hunt suggests humans arrived in North America earlier than previously thought | Laura Santhanam | PBS News Hour | Digital Media Literacy + Cyber Arts + Performance Centers Connected to Fiber Networks | Scoop.it

Bone fragments from seven horses and a camel suggest that the First Americans hunted and butchered these animals in North America at least 13,300 years ago after migrating from northeast Asia, hundreds of years earlier than previously thought.

According to a study published today in the Proceedings of the National Academy of Sciences, these bones suggest that people were active at the Wally’s Beach location near Calgary, Alberta. That’s about 300 years before the Clovis people emerged — a group of prehistoric humans who had been previously considered the first settlers of the Americas, having arrived 13,000 years ago.

This finding is consistent with the last decade of research into who were the real ancestors of the Native Americans, explained Michael Waters, an anthropologist from Texas A&M University and director for the Center for the Study of the First Americans.


“It represents to us just more evidence that people were in the Americas before Clovis and that these people had some kind of weaponry that we haven’t found yet,” Waters said. “From 15,000 years on, they were moving across the landscape, hunting horse, camel, mastodon and mammoth.”


When he first looked in to the site at Wally’s Beach, Waters wondered if the estimated dates of the animal remains, originally pinned at roughly 13,000 years ago, were wrong. He noted the absence of distinctive Clovis tools, such as flaked-off stone spearheads made at the end of the Ice Age, at the Wally’s Beach site.

Precision planetary lander technology tested by NASA | David Szondy | GizMag.com

In anticipation of more ambitious planetary missions, NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, in collaboration with Masten Space Systems in Mojave, California, has recently been testing new landing technologies using an Autonomous Descent and Ascent Powered-flight Testbed (ADAPT). Aimed at developing new systems for landing on Mars and other planets with much greater precision, a new imaging landing system and algorithm were tested using the demonstration vehicle on two successful flights.

Making a precision landing on Earth from space is a remarkable achievement, but for a robotic probe landing on another planet without the benefit of ground control, GPS, or navigation beacons, that's another matter entirely. Relying on pre-programmed instructions and onboard instruments, landers like Curiosity must settle for aiming at ellipses covering hundreds of square miles. Also, because landers don't include imaging systems for controlling navigation, they are literally flying blind.

Israel: 500,000-Year-Old 'Swiss Army Knife' Discovered | Macrina Cooper-White | HuffPost,com

Israel: 500,000-Year-Old 'Swiss Army Knife' Discovered | Macrina Cooper-White | HuffPost,com | Digital Media Literacy + Cyber Arts + Performance Centers Connected to Fiber Networks | Scoop.it

A set of half-a-million-year-old stone tools -- including what's being called a prehistoric "swiss army knife" -- have scientists going gaga.

The tools were found alongside the remains of butchered animals, such as an elephant rib bone bearing cut marks (see photo above), at a dig site in Revadimin, Israel in 2004.

Now, researchers who recently analyzed the finds have discovered the tools are covered in animal fat, and are calling them the first direct evidence of the use of stone tools by ancient human ancestors for animal butchery.

"Archaeologists have until now only been able to suggest scenarios about the use and function of such tools. We don't have a time machine," Prof. Ran Barkai, an archaeologist at Tel Aviv University's Department of Archaeology and Ancient Near Eastern Cultures and one of the researchers, said in a written statement. "It makes sense that these tools would be used to break down carcasses, but until evidence was uncovered to prove this, it remained just a theory."
