Is What WikiLeaks Does Journalism? Good Question

Is What WikiLeaks Does Journalism? Good Question: "


While the U.S. government tries to determine whether what WikiLeaks and front-man Julian Assange have done qualifies as espionage, media theorists and critics alike continue to debate whether releasing those classified diplomatic cables qualifies as journalism. It’s more than just an academic question — if it is journalism in some sense, then Assange and WikiLeaks should be protected by the First Amendment and freedom of the press. The fact that no one can seem to agree on this question emphasizes just how deeply the media and journalism have been disrupted, to the point where we aren’t even sure what they are any more.


The debate flared up again on the Thursday just before Christmas, with a back-and-forth Twitter discussion involving a number of media critics and journalists, including MIT Technology Review editor and author Jason Pontin, New York University professor Jay Rosen, PhD student Aaron Bady, freelance writer and author Tim Carmody and several other occasional contributors. Pontin seems to have started the debate by saying — in a comment about a piece Bruce Sterling wrote on WikiLeaks and Assange — that the WikiLeaks founder was clearly a hacker, and therefore not a journalist.


Pontin’s point, which he elaborated on in subsequent tweets, seemed to be that because Assange’s primary intent is to destabilize a secretive state or government apparatus through technological means, then what he is doing isn’t journalism. Not everyone was buying this, however. Aaron Bady — who wrote a well-regarded post on Assange and WikiLeaks’ motives — asked why he couldn’t be a hacker and a journalist at the same time, and argued that perhaps society needs to have laws that protect the act of journalism, regardless of who practices it or what they call themselves.


Rosen, meanwhile, was adamant that WikiLeaks is a journalistic entity, period, and journalism prof and author Jeff Jarvis also echoed this point. Tim Carmody argued that the principle of freedom of the press enshrined in the First Amendment was designed to protect individuals who published pamphlets and handed them out in the street just as much as it was to protect large media entities, and Aaron Bady made a point that I have tried to make as well, which is that it’s difficult to criminalize what WikiLeaks has done without also making a criminal out of the New York Times.



This debate has been going on since before the diplomatic cables were released, ever since Julian Assange first made headlines with leaked video footage of American soliders firing on unarmed civilians in Iraq. At the time, Rosen — who runs an experimental journalism lab at NYU — called WikiLeaks “the first stateless news organization,” and described where he saw it fitting into a new ecosystem of news. Not everyone agreed, however: critics of this idea said that journalism had to have some civic function and/or had to involve journalists analyzing and sorting through the information.


Like Rosen and others, I’ve tried to argue that in the current era, media — a broad term that includes what we think of as journalism — has been dis-aggregated or atomized; in other words, split into its component parts, parts that include what WikiLeaks does. In some cases, these may be things that we didn’t even realize were separate parts of the process to begin with, because they have always been joined together. And in some cases they merge different parts that were previously separate, such as the distinction between a source and a publisher. WikiLeaks, for example, can be seen as both.


And while it is clearly not run by journalists — and to a great extent relies on journalists at the New York Times, The Guardian and other news outlets to do the heavy lifting in terms of analysis of the documents it holds and distributes — I think an argument can be made that WikiLeaks is at least an instrument of journalism. In other words, it is a part of the larger ecosystem of news media that has been developing with the advent of blogs, wikis, Twitter and all the other publishing tools we have now, which Twitter founder Ev Williams I think correctly argued are important ways of getting us closer to the truth.


Among those taking part in the Twitter debate on Thursday was Chris Anderson, a professor of media culture in New York who also writes for the Nieman Journalism Lab, and someone who has tried to clarify what journalism as an ecosystem really means and how we can distinguish between the different parts of this new process. In one post at the Nieman Lab blog, for example, he plotted the new pieces of this ecosystem on a graph with two axes: one going from “institutionalized” to “de-institutionalized” and the other going from “pure commentary” to “fact-gathering.” While WikiLeaks doesn’t appear on Anderson’s graph, it is clearly part of that process.


Regardless of what we think about Julian Assange or WikiLeaks — or any of the other WikiLeaks-style organizations that seem to be emerging — this is the new reality of media. It may be confusing, but we had better start getting used to it.

Samuel Sevian, 9, is youngest US national chess master

Samuel Sevian, 9, is youngest US national chess master: "Samuel Sevian, 9, likes to read, watch Disney's 'Suite Life on Deck' on TV, and play soccer. He's also the youngest United States 'National Master' in chess. He earned the title earlier this month. From the San Jose Mercury News:


 Live Media Site568 2010 1220 20101220  Ssjm1221Chesskid~1 Gallery
Samuel spends at least two hours a day studying chess moves in books, playing with his dad, and practicing on Skype with his coach, international master Andranik Matikozyan, who lives in Los Angeles, where the Sevians are heading for Christmas.



'I met Samuel three years ago in Santa Monica at a tournament when he was 7,' Matikozyan said. 'When I saw him playing, I was amazed. I thought, 'This kid is really talented.' '


Sevian said his son does very well in school, too, often maxing out on his math scores.


'He is obviously very gifted,' said Don Callejon Principal Hans Barber. 'On Thanksgiving break, we gave kids a math challenge, and he won. He has a problem-solving mind.'


Barber gave Samuel lots of credit, too, for attending tournaments, doing so well in school and 'holding it all together.' Samuel is 'too intense' to participate in the school's chess club, but Barber is sure that he inspired other students to take up the game...



'I like the tactics and the combinations,' said Samuel, who comes from a culture where chess players are held in high esteem. The Sevian family is from Armenia.


'In Armenia, chess is very big,' (his father) Armen Sevian said. 'It's certainly not a geek sport. Chess players are compared to rock stars.'

Molecular biologist on the dangers of pornoscanners

Molecular biologist on the dangers of pornoscanners: "Jason Bell, 'a molecular biologist and biophysicist... a Ph.D. candidate in Steve Kowalczykowski's lab at UC Davis,' has posted a detailed critique of the research on the safety of airport backscatter radiation scanners. His specialty is the 'molecular mechanism of how mutations in the breast cancer susceptibility gene, BRCA2, result in cancer,' and he's posted a detailed, lay-friendly explanation of the scientific concerns expressed by the UCSF team that believes that they are unsafe for use.


Which brings me to how the scanner works. Essentially, it appears that an X-ray beam is rastered across the body, which highlights the importance of one of the specific concerns raised by the UCSF scientists... what happens if the machine fails, or gets stuck, during a raster. How much radiation would a person's eye, hand, testicle, stomach, etc be exposed to during such a failure. What is the failure rate of these machines? What is the failure rate in an operational environment? Who services the machine? What is the decay rate of the filter? What is the decay rate of the shielding material? What is the variability in the power of the X-ray source during the manufacturing process? This last question may seem trivial; however, the Johns Hopkins Applied Physics Laboratory noted significant differences in their test models, which were supposed to be precisely up to spec. Its also interesting to note that the Johns Hopkins Applied Physics Laboratory criticized other reports from NIST (the National Institute of Standards and Technology) and a group called Medical and Health Physics Consulting for testing the machine while one of the two X-ray sources was disabled (citations at the bottom of the page).


These questions have not been answered to any satisfaction and the UCSF scientists, all esteemed in their fields and members of the National Academy of Sciences have been dismissed based on a couple of reports seemingly hastily put together by mid-level government lab technicians. The documents that I have reviewed thus far either have NO AUTHOR CREDITS or are NOT authored by anyone with either a Ph.D. or a M.D., raising serious concerns of the extent of the expertise of the individuals and organizations evaluating these machines. Yet, the FDA and TSA continue to dismiss some of the most talented scientists in the country...


Furthermore, when making this comparison, the TSA and FDA are calculating that the dose is absorbed throughout the body. According the simulations performed by NIST, the relative absorption of the radiation is ~20-35-fold higher in the skin, breast, testes and thymus than the brain, or 7-12-fold higher than bone marrow. So a total body dose is misleading, because there is differential absorption in some tissues. Of particular concern is radiation exposure to the testes, which could result in infertility or birth defects, and breasts for women who might carry a BRCA1 or BRCA2 mutation. Even more alarming is that because the radiation energy is the same for all adults, children or infants, the relative absorbed dose is twice as high for small children and infants because they have a smaller body mass (both total and tissue specific) to distribute the dose. Alarmingly, the radiation dose to an infant's testes and skeleton is 60-fold higher than the absorbed dose to an adult brain!

Accurately weighing a pulsating giant

Accurately weighing a pulsating giant: "






Cepheid variables are a
class of stars with a luminosity that changes as a function of time. Cepheids are well-studied
astronomical bodies—they were first discovered in 1784—and
subsequent work has been able to identify a precise relationship
linking their luminosity and pulsation period. Because of this
well-defined relationship, they have been employed as standard candles
and used to accurately measure intergalactic distances. In fact, it was
calculations based on Cepheids that led Hubble and Humason to formulate
Hubble's law and conclude that the Universe was expanding.



Despite all that we know, however, there is a problem when it comes to Cepheids. Calculations of their mass based on two
different stellar theories leads to two very different numbers. In fact, using
the theory of pulsating stars will result in a mass prediction 20
percent less than that arrived at using the theory of stellar evolution. This problem has troubled astrophysicists since the 1960s.



To resolve this discrepancy,
astronomers need an independent measurement of the mass of a Cepheid to
see which theory—if either—is correct. Prior attempts at mass
measurements have given estimates
to within only 15 to 30 percent accuracy, not enough to resolve the
discrepancy between the two theories. An independent measurement, to get the right precision, requires a Cepheid to be one half of a pair of binary
eclipsing stars that orbit each other in a plane that would be seen
edge-on from Earth. Since neither Cepheids or binary eclipsing stars in
such orbital arrangements are common, a combination of both is
exceedingly rare.



This week's
edition of Nature contains a letter reporting on just such a rare find.
OGLE-LMC-CEP0227 is a stellar pair in the Large Magellanic
Cloud that orbits us in the right orientation and contains a Cepheid
star. According to the paper, the Cepheid variable star pulsated every
3.8 days and the two orbited each other every 310 days.



By measuring the orbits of both
stars, as well as the contraction-and-expansion of the Cepheid over the
entire orbit, astronomers were able to determine the Cepheid's mass to within 1 percent error. The
observed mass matched exactly with that predicted by the theory of
stellar pulsation; the larger mass predicted by the theory of stellar
evolution was shown to be largely in error.

Future work by the group
will involve looking for more such binary systems. With more data on
hand, they believe they can much more accurately pin down the distance
between Earth and the Large Magellanic Cloud, a
result that will greatly increase the accuracy of our cosmic-scale distance estimates.

What does stoning a person to death entail?

What does stoning a person to death entail?: "201011241146

Canada's National Post created a two-page spread to explain the procedure for stoning condemned adulterer to death.

Since 1980, at least 150 men and women have been stoned to death in Iran, said Farshad Hoseini, head of the International Committee against Execution, who has compiled a report on the practice from media reports and human rights organizations.

However, he cautions in the report, 'It should be pointed out that obtaining a true and complete list of the victims is extremely difficult, if not totally impossible, due to the regime's systematic censorship of such news.'

He added, 'Stoning in Iran is a political tool in the hands of an Islamic regime to oppress the society as a whole in one of the most savage ways. The overwhelming majority of the victims of stoning are women. Stoning in Iran is therefore a tool, among many such religious, oppressive tools, for keeping women in their place.'

Some Android apps caught covertly sending GPS data to advertisers

Some Android apps caught covertly sending GPS data to advertisers: "




The results of a study conducted by researchers from Duke University, Penn State University, and Intel Labs have revealed that a significant number of popular Android applications transmit private user data to advertising networks without explicitly asking or informing the user. The researchers developed a piece of software called TaintDroid that uses dynamic taint analysis to detect and report when applications are sending potentially sensitive information to remote servers.



They used TaintDroid to test 30 popular free Android applications selected at random from the Android market and found that half were sending private information to advertising servers, including the user's location and phone number. In some cases, they found that applications were relaying GPS coordinates to remote advertising network servers as frequently as every 30 seconds, even when not displaying advertisements. These findings raise concern about the extent to which mobile platforms can insulate users from unwanted invasions of privacy.

Scientific estimate puts total BP oil spill at 4.4 million barrels [Disaster]

Scientific estimate puts total BP oil spill at 4.4 million barrels [Disaster]: "
Research published in Science shows that the BP oil leak pumped out approximately of 4.4 million barrels of oil before being completely capped. That's around 185 million gallons, or 700 million liters. Scientists from Columbia University's Lamont-Doherty Earth Observatory studied high resolution footage of the plume, and used a technique known as optical plume velocimetry to gauge the volume. From this, they state that between 22 April and 3 June the output was 56,000 barrels per day, ±21%, after which it increased to 68,000 barrels per day, ±19%, until it was capped on the 15th of July. This is a rate substantially higher than those originally put forth by the Government or BP, which originally started at just 1,000 barrels per day, but in line with current estimates. More »

Extreme X-rays may be signature of lame black hole

Extreme X-rays may be signature of lame black hole: "




Last summer, we reported on an extremely bright object that may have been an intermediate mass black hole. The existence of black holes this size has been hotly debated, in part because we've never observed one. The object, 2XMM J011028.1-460421 or (more
conveniently) HLX-1, is a source of ultraluminous X-rays near the
spiral galaxy ESO
243-49. Newly reported results, appearing in an upcoming edition of The Astrophysical Journal, confirm that HLX-1 is over 100 times brighter than typical objects in
its class, and a factor of 10 times more luminous than its nearest
peer.


The prior work could not conclusively rule out the possibility that the X-rays were produced by a foreground star or background galaxy. With new observations made using the European Southern Observatory's Very Large Telescope
in Chile, the researchers were able to obtain an optical spectrum of
HLX-1. With this spectrum, it was possible to calculate a
precise distance between HLX-1 and Earth.


Using some more advanced techniques, it was possible to separate the light from HLX-1 and the light generated by ESO
243-49. The analysis proved that HLX-1 is indeed part of ESO
243-49, and not one of the alternatives, like a supermassive black hole in the center of a distant
galaxy, or a source in our own galaxy. Given its location, the previous brightness
calculations are correct.

While still not conclusive, these new
findings strengthen the case that HLX-1 is an intermediate mass black
hole. According to Sean Farrell, one of the authors, 'This [the result] is very difficult to explain without the presence of an
intermediate mass black hole of between ~500 and 10,000 times the mass
of the Sun. HLX-1 is therefore (so far!) weathering the scrutiny of the
international astronomy community.' The team has secured time on the Hubble Space Telescope to take the
highest resolution images of the host galaxy to date in the hopes of learning
more about this intriguing object.

SD, SDHC and SDXC cards get speed injection

SD, SDHC and SDXC cards get speed injection: "

The SD Association has announced that it has increased the speed of its latest edition of SD memory cards, by creating a new, dual-row pin memory card design.

The new system is fully backwards compatible with readers, in that it doesn't alter the shape or size of the cards and it has been designed for use with both full-size and micro versions of SD.

No new system is complete without a fancy number after it, so the SD Association is calling this now generation of cards SD 4.0.

HD support

'Our innovative dual-row pin design ultimately lets consumers using equipped products to manage the massive storage capacity found on SDXC memory cards at incredible speeds,' explained Norm Frentz, chairman of the SD Association about the new setup.

'SD can now support high definition video from Hollywood movie studios, television broadcasts, or HD videos taken on your latest vacation. SD is a very popular, extremely portable and easy-to-use storage medium that has enhanced the enjoyment and portability of music, photos and data.'

The new speedier versions of SD have a UK release date of 2011, after the 4.0 specification is finalised.
