Middleton high schoolers know about 'iPhone' scams; simply delete ...

February 4, 2013 ? 1:36 pm

By Robb Hicken/BBB?s chief storyteller

Speaking with students at Middleton High School last week as part of a ?Know Your Options? session, I found out just what they thought about smartphones.

I was not surprised to see that the upper classes were tuned into staying in touch by smartphone. Fewer of the younger students ? freshmen and sophomores ? owned the devices.

Of the upper classmen, nearly half already had a smartphone. And, of those who had a phone, none reported falling for the ?you?ve won a gift card? text scam. Their response was short and simple: Don?t know who it is? Delete.

The students said the texts they receive the most are: You?ve won an iPhone 5 or a $1,000 Walmart prize.

Smart students because most knew what lay in store should they click the link for the alleged prize. Clicking the link may download a harmful virus to their mobile device.

It?s important to remember that a smart phone is basically a hand-held computer, and is susceptible to viruses, malware or spyware just like a laptop or a desktop computer.? In addition, most students understood that by the time they were in college they would be using smartphones or a tablet for multiple tasks ? from paying bills to writing class papers.

I passed along ?these tips:

  • Never reply to an email that is asking you for personal information. Even if the email appears to be from a trusted source, this may be a phishing attack, where someone is trying to illegitimately obtain your personal or financial information. Delete the email immediately.
  • Do not click on any links from sources that you are unfamiliar with. This may be a phishing attack, where someone is trying to redirect you to a website that may automatically trigger malicious code and infect your computer. If you really want to check out a link sent to you by email, research the company or individual first to confirm they are trustworthy. If so, then manually retype the link into a secure web browser.
  • Keep anti-spyware, anti-virus and anti-spam software up to date. While you are ultimately responsible for keeping personal and financial information private, these technologies are designed to help keep phishing attacks to a minimum.
  • Never give personal information over the phone. Take the time to verify what the caller is claiming by visiting BBB.org to look up the organization they are representing.
  • A true sweepstakes will not make its winner pay fees. Many scams involve mailing or wiring a portion of the prize back for fees or taxes. Legitimate prizes do not come with processing fees and taxes are paid directly to the Internal Revenue Service (IRS) after winnings are collected.

More often, text messages like these ? including claims you have won merchandise or gift cards from popular stores and brands ? are phishing scams. Clicking the link leads you to a form that asks you to provide your personal information so in order to claim your prize. The scammers either use that information to open fraudulent accounts in your name or sell it to others.

The Channels : SBCC student wins award for script in SBIFF

MCLSBIFF03

Gabriella Guillen walks off with a $500 gift certificate for Samy's Camera after winning the Santa Barbara International Film Festival's 10-10-10 Student Screenwriting Competition with her screenplay 'Paradise Cafe.'

A City College student won the Santa Barbara Film Festival?s tenth annual 10-10-10 Student Screenwriting Competition with her dark comedy script, ?Paradise Cafe.?

Gabriella Guillen earned her award after the ten-minute films were aired and judged at 1 p.m. on Sunday, February 3 at the Lobero Theatre. The competition?s assigned genre was comedy, but each screenplay had an entirely different approach to the prompt, resulting in a dramatic win.

?I didn?t think I had a chance at all,? Guillen said. ?I was thinking ?This is so dark, no one is going to laugh, no one is going to like it.? I was so nervous. I was sure I wasn?t going to win.?

The 10-10-10 Student Filmmaking and Screenwriting Competition brings together student writers, filmmakers and industry professionals that mentor the students throughout the competition.

The screenwriters have ten days to complete a ten-minute screenplay, which is then assigned a student director who has ten days to film, direct and edit the short film. Guillen worked closely with her director, Benjamin Goalabre.

?My director was great. He was very accepting and every draft I turned in, he loved, so it was really nice to work with him,? Guillen said.

Her screenplay, ?Paradise Cafe? distorts the stereotypical genie-in-a-bottle fairytale with its bar setting and reluctant protagonist. Though it provided laughter throughout, its haunting finale left audience members with hairs raised.

?I originally wanted it to be a dark comedy because I was afraid of comedy. I?m much better at darker things, honestly, so going into it I knew what I wanted to do,? Guillen said.

This is her third year as a City College student. Beginning as a film production major, she has experienced a change of interest.

?I?m a film production student, but the past couple semesters I?ve been taking writing classes so I?m actually leaning more towards writing now,? Guillen said. ?Last semester I took a writing for television class with Ed Caplan and he pushed me towards entering [the competition].?

Outside of the Lobero, high school and college students congregated with other contestants, press and SBIFF workers. The theater quickly filled to maximum capacity speckled with parents, press and judges, but mostly young, eager faces.

?Paradise Cafe? director and City College student, Benjamin Goalabre, explained that filmmakers had to draw screenplays from a hat at random.

?I picked the best script, obviously,? Goalabre said. ?We worked together and it went really well. She won because she had the best story.?

Guillen and Goalabre?competed with other City College students. Student director Johan Bodell led his team in creating ?Killer Raise,? a horror comedy that was one of five college-level finalists in the competition.

?Even if we don?t win, it?s a good experience,? Bodell said. ?We can submit the film to other contests and see what happens.

The winning film will be shown at the Santa Barbara Film Festival?s closing night festivities in the Arlington Theatre.

An artists' spat over Putin and his adoption ban joins a long tradition in Russian politics

MOSCOW - When famed viola player Yuri Bashmet declared that he "adored" President Vladimir Putin, he stirred little controversy in a country where classical musicians have often curried favour with the political elite.

But political drama spilled into the orchestra pit last month when Bashmet refused to condemn a new law prohibiting Americans from adopting Russian children, and in response the beloved singer Sergei Nikitin cancelled his appearance at a concert celebrating the violist's 60th birthday.

The spat joins a long Russian tradition of artists who have jumped ? or been dragged ? into the political fray. From composer Dmitri Shostakovich, who lived in fear of arrest under dictator Josef Stalin, to the cellist Mstislav Rostropovich, who returned to a liberalizing Soviet Union in 1991 and took up arms to defy Communist hardliners, Russian musicians and other artists have had a habit of becoming politicized figures.

At the core of the argument today is a question about what an artist's role should be in Putin's Russia: Attracting generous state funding for bigger and better artistic projects? Or challenging the political system in a way most ordinary citizens cannot afford to do?

Some of Russia's cultural figures brought their star power to the anti-Putin rallies that rocked Moscow last winter. Others were recruited to back up Putin as he ran for a third term as Russia's president. As the expression goes: "A poet in Russia is always more than a poet."

Actor and theatre director Yevgeny Mironov appeared in a pro-Putin campaign ad in which he gave heartfelt thanks to Putin for keeping Russia ? and his Moscow theatre ? afloat. Some of his fellow actors loudly refused.

Actress Chulpan Khamatova, who depends on government support for charity work for children, filmed a similar pro-Putin ad, but the delivery was tortured, as if she were speaking under duress. And she was one of the many cultural figures who signed a petition condemning the adoption bill.

The ban, which went into effect Jan. 1, proved controversial even among many Putin loyalists in the intelligentsia, who see the Kremlin as playing politics at the expense of Russia's orphans. Tens of thousands of people took part in a Jan. 13 protest march through Moscow, one of the largest anti-Putin demonstrations the city had seen in many months.

The adoption ban was in response to the Magnitsky Act, a U.S. law that imposes sanctions on Russians accused of involvement in the prison death of whistleblowing lawyer Sergei Magnitsky and other rights abuses.

Yuri Norshteyn, Russia's most beloved animator, took Putin to task over Magnitsky during an awards ceremony on Jan. 19. Norshteyn noted that Putin had attributed Magnitsky's death to heart failure, but said that in fact the lawyer had died because of "a failure of Putin's heart."

The audience erupted with cheers and applause.

Discontent over the adoption ban entered the classical music world at a news conference Bashmet gave ahead of his birthday jubilee concert on Jan. 24. The floppy-haired violist, who is the conductor of two Moscow orchestras and a famed soloist in his own right, gave an equivocal answer when asked about his stance on the adoption ban, refusing to condemn the law in its entirety.

In an interview with The Associated Press on Jan. 27, Bashmet said he didn't think the fate of children should be decided by anti-American legislation, but he asserted that the adoption ban would end up helping Russia's orphans by raising awareness within the country about the tens of thousands of children in need of families.

"There are things that need to be decided within the country, and it's good that this question has been raised in such a controversial way, so that now the president has decreed that it will be at the centre of attention," Bashmet told the AP. "Our government is now responding to this, to the betterment of these children."

That stance didn't sit well with Nikitin, a bard in the Russian folk tradition. He said that it didn't bother him if "Bashmet adores the president," but his ambiguous justification of the adoption ban took things too far.

"This (the adoption issue) doesn't have anything to do with politics," Nikitin said. "It's about being humane, being humanitarian, about morality."

Bashmet may be an extreme example of an artist showing affection for Putin, but classical musicians have rarely been immune to politics.

Valery Gergiev, director of the Mariinsky Theater in St. Petersburg, has been outspokenly supportive of the Putin regime. After Russia and Georgia fought a brief war in 2008 over the breakaway Georgian region of South Ossetia, he conducted a concert in front of a destroyed government building in the South Ossetian capital.

The cellist Rostropovich, whose support for Soviet dissidents had led to his exile in the United States in the 1970s, returned to the Soviet Union as the Communist regime was crumbling. Wielding a Kalashnikov, he stood with protesters who had rallied around Boris Yeltsin in defiance of Communist hardliners trying to take power in the August 1991 coup.

Other musicians have been much less willing participants when it comes to politics, doing their best to avoid the political fray. This was particularly true when the risks were greater, as they were in Soviet times, when even a discordant note or a suggestive motif could bring accusations of deviating from the political line.

The composer Shostakovich received a scathing critique of his experimentalism in 1936, infamously titled "Muddle Instead of Music" and published in the Soviet Union's most important newspaper. With the Stalinist purges moving at full throttle, Shostakovich backed away from some of his more avant-garde music, taking more care to adhere to the political line.

But Shostakovich, like his contemporary Sergei Prokofiev, was also protected by his status. Great musicians of the Soviet period became a source of patriotism and a means of challenging the West's dominance. Despite the heavy weight of Stalinist repression, Shostakovich and Prokofiev created some of the most cherished, experimental and at times critical music of the 20th century.

After Stalin's death, many of Shostakovich's and Prokofiev's compositions that were interpreted as anti-fascist during the dictator's life were recast as artistic protests against the Stalinist terror.

Nikitin believes in the examples set by Prokofiev and Shostakovich ? great artists who were among the few people who could attempt to oppose, even if only through their music, the existing regime.

"The government and state officials, including the president, should be grateful to these artists, that they give them the opportunity to experience this kind of art, and in this way to make life in our country richer," he said.

In Soviet times, cinema also was under strict government censorship. When Stalin was in power, he decided personally which films could be shown and which were to be stashed "on the shelf." Despite this, the Soviet era is remembered as the height of Russian filmmaking, from the early experimentalism of Sergei Eisenstein to the charming, Oscar-winning "Moscow Doesn't Believe in Tears."

After the 1991 collapse of the Soviet Union, things changed drastically for the film industry. A style called "chernukha," or blackness, became the vogue among many Russian filmmakers, who made dark and violent movies showing contemporary life as a bleak moral vacuum. Others, like director Nikita Mikhailkov, took a different tack by producing upbeat, patriotic films, attracting generous funding in the process.

IRL: Skooba Cable Stable, Kanex mySpot and the HTC One X+

Welcome to IRL, an ongoing feature where we talk about the gadgets, apps and toys we're using in real life and take a second look at products that already got the formal review treatment.

We've got some practical considerations on our minds this week. Sensible things, like managing a mess of cables or getting online from hotel rooms. We've found some products that serve us well on both fronts, but there's still at least one conundrum we can't quite resolve: is it better to get a cheapie One X or a slightly faster One X+? We'll hash that one out after the break -- and you can do the same in the comments.

Iran says US offer of direct talks a 'step forward, but...'

Iranian Foreign Minister Ali Akbar?Salehi responded positively to the US offer, but blamed previous negotiation failures on the US.?

By Adrian Croft and Alexandra Hudson,?Reuters / February 3, 2013

Iran said on Sunday it was open to a US offer of direct talks on its nuclear program and that six world powers had suggested a new round of nuclear negotiations this month, but without committing itself to either proposal.

Skip to next paragraph

' + google_ads[0].line2 + '

Diplomatic efforts to resolve a dispute over Iran's nuclear program, which Tehran says is peaceful but the West suspects is intended to give Iran the capability to build a nuclear bomb, have been all but deadlocked for years, while Iran has continued to announce advances in the program.

Iranian Foreign Minister Ali Akbar?Salehi said a suggestion on Saturday by US Vice President Joe Biden that Washington was ready for direct talks with Iran if Tehran was serious about negotiations was a "step forward."

"We take these statements with positive consideration. I think this is a step forward but ... each time we have come and negotiated it was the other side unfortunately who did not heed ... its commitment," Mr. Salehi?said at the Munich Security Conference where Mr. Biden made his overture a day earlier.

He also complained to Iran's English-language Press TV of "other contradictory signals," pointing to the rhetoric of "keeping all options on the table" used by US officials to indicate they are willing to use force to keep Iran from obtaining a nuclear weapon.

"This does not go along with this gesture [of talks] so we will have to wait a little bit longer and see if they are really faithful this time," Salehi?said.

Iran is under a tightening web of sanctions. Israel has also hinted it may strike if diplomacy and international sanctions fail to curb Iran's nuclear drive.

In Washington, Army Gen. Martin Dempsey, the top US military officer, said in an interview broadcast on Sunday that the United States has the capability to stop any Iranian effort to build nuclear weapons, but Iranian "intentions have to be influenced through other means."

General Dempsey, chairman of the Joint Chiefs of Staff, made his comments on NBC's program "Meet the Press," speaking alongside outgoing Defense Secretary Leon Panetta.

Panetta said current US intelligence indicated that Iranian leaders have not made a decision to proceed with the development of a nuclear weapon.

"But every indication is they want to continue to increase their nuclear capability," he said. "And that's a concern. And that's what we're asking them to stop doing."

The new US secretary of state, John Kerry, has said he will give diplomacy every chance of solving the Iran standoff.

The best chance

With six-power talks making little progress, some experts say talks between Tehran and Washington could be the best chance, perhaps after Iran has elected a new president in June.

Negotiations between Iran and the six powers ??Russia, China, the United States, Britain, France, and Germany ??have been deadlocked since a meeting last June.

EU officials have accused Iran of dragging its feet in weeks of haggling over the date and venue for new talks.

Salehi?said he had "good news," having heard that the six powers would meet in Kazakhstan on Feb. 25.

A spokesman for EU foreign policy chief Catherine Ashton, who coordinates the efforts of the six powers, confirmed that she had proposed talks in the week of Feb. 25 but noted that Iran had not yet accepted.

Kazakhstan said it was ready to host the talks in either Astana or Almaty.

Salehi?said Iran had "never pulled back" from the stuttering negotiations with the six powers. "We still are very hopeful. There are two packages, one package from Iran with five steps and the other package from the [six powers] with three steps."

Iran raised international concern last week by announcing plans to install and operate advanced uranium enrichment machines. The EU said the move, potentially shortening the path to weapons-grade material, could deepen doubts about the peaceful nature of Iran's nuclear program.

Prime Minister Benjamin Netanyahu said on Sunday that Israel's mission to stop its arch-enemy from acquiring nuclear weapons was "becoming more complex, since the Iranians are equipping themselves with cutting-edge centrifuges that shorten the time of [uranium] enrichment."

"We must not accept this process," said Netanyahu, who is trying to form a new government after winning an election last month. Israel is generally believed to be the only country in the Middle East with nuclear weapons.

Iwata: Cloud gaming not the future | Nintendo Everything

February 2nd, 2013 Posted in General Nintendo, News, Posted by Valay

Satoru Iwata told investors at a financial results briefing earlier this week that Nintendo does not believe ?cloud gaming is the future?. Although he acknowledged that it has its advantages (and disadvantages), Nintendo is ?trying to work hard on a future where gaming only consoles are not gone.?

An unofficial translation from the meeting reads:

?There are things you can do with cloud gaming and there are things you cant do. We don?t agree that cloud gaming is the future and we are trying to work hard on a future where gaming only consoles are not gone. Unified platforms are for us not platforms that are one but rather platforms that have the same development architecture. This also means that there could be more platforms.?

Shigeru Miyamoto, who was also in attendance, spoke about the challenge of creating new development environments for Wii U and 3DS:

?We needed to create new development environments for Wii U and 3DS unlike Wii which reused the GameCube architecture. We are unifying our development teams to accommodate this challenge and minimize the losses while preparing the shift. I think handhelds and consoles will coexist as the aim is different.

Mutant gene gives pigeons fancy hairdos

Friday, February 1, 2013

University of Utah researchers decoded the genetic blueprint of the rock pigeon, unlocking secrets about pigeons' Middle East origins, feral pigeons' kinship with escaped racing birds, and how mutations give pigeons traits like a fancy feather hairdo known as a head crest.

"Birds are a huge part of life on Earth, and we know surprisingly little about their genetics," especially compared with mammals and fish, says Michael D. Shapiro, one of the study's two principal authors and an assistant professor of biology at the University of Utah. "There are more than 10,000 species of birds, yet we know very little about what makes them so diverse genetically and developmentally."

He adds that in the new study, "we've shown a way forward to find the genetic basis of traits ? the molecular mechanisms controlling animal diversity in pigeons. Using this approach, we expect to be able to do this for other traits in pigeons, and it can be applied to other birds and many other animals as well."

The study appears Jan. 31 on Science Express, the website of the journal Science. Shapiro led the research with Jun Wang of China's BGI-Shenzhen (formerly Beijing Genomics Institute) and other scientists from BGI, the University of Utah, Denmark's University of Copenhagen and the University of Texas M.D. Anderson Cancer Center in Houston.

Key findings of the study of pigeons, which first were domesticated some 5,000 years ago in the Mediterranean region:

  • The researchers sequenced the genome, or genetic blueprint, of the rock pigeon, Columba livia, among the most common and varied bird species on Earth. There are some 350 breeds with different sizes, shapes, colors, color patterns, beaks, bone structure, vocalizations and arrangements of feathers on the feet and head ? including head crests that come in shapes known as hoods, manes, shells and peaks.

The pigeon is among the few bird genomes sequenced so far, along with those of the chicken, turkey, zebra finch and a common parakeet known as a budgerigar or budgie, so "this will give us new insights into bird evolution," Shapiro says.

  • Using innovative software developed by study co-author Mark Yandell, a University of Utah professor of human genetics, the scientists revealed that a single mutation in a gene named EphB2 causes head and neck feathers to grow upward instead of downward, creating head crests.

"This same gene in humans has been implicated as a contributor to Alzheimer's disease as well as prostate cancer and possibly other cancers," Shapiro says, noting that more than 80 of the 350 pigeon breeds have head crests, which play a role in attracting mates in many bird species.

  • The researchers compared the pigeon genome to those of chickens, turkeys and zebra finches. "Despite 100 million years of evolution since these bird species diverged, their genomes are very similar," Shapiro says.
  • The study turned up more conclusive evidence that major pigeon breed groups originated in the Middle East, and that North American feral pigeons ? which are free-living but not wild ? are close relatives of racing pigeons, named racing homers.

A Genome for the Birds, a Gene for Head Crests

The study assembled 1.1 billion base pairs of DNA in the rock pigeon genome, and the researchers believe there are about 1.3 billion total, compared with 3 billion base pairs in the human genome. The rock pigeon's 17,300 genes compare with about 21,000 genes in people.

The researchers first constructed a "reference genome" ? a full genetic blueprint ? from a male of the pigeon breed named the Danish tumbler. They did less complete sequencing of two feral pigeons and 38 other pigeons from 36 breeds.

Shapiro says his team's study is the first to pinpoint a gene mutation responsible for a pigeon trait, in this case, head crests.

"A head crest is a series of feathers on the back of the head and neck that point up instead of down," Shapiro says. "Some are small and pointed. Others look like a shell behind the head; some people think they look like mullets. They can be as extreme as an Elizabethan collar."

The study found strong evidence that the EphB2 (Ephrin receptor B2) gene acts like an on-off switch to create a head crest when mutant, and no head crest when normal. It also showed the mutation and related changes in nearby DNA are shared by all crested pigeons, so the trait evolved just once and was spread to numerous pigeon breeds by breeders. They ruled out the alternate possibility the mutation arose several times independently in different breeds.

The researchers analyzed full or partial genetic sequences for 69 crested birds from 22 breeds, and 95 uncrested birds from 57 breeds. They found a perfect association between the mutant gene and the presence of head crests.

"The way we tracked this trait was innovative," Shapiro says. "We used gene-finding software from Mark Yandell's group that was developed to find mutations that control human diseases. We adapted this software to find mutations that control interesting traits in pigeons. This should be extendable to other animals as well."

The scientists also showed that while the head crest trait becomes apparent in juvenile pigeons, the mutant gene affects pigeon embryos by reversing the direction of feather buds ? from which feathers later grow ? at a molecular level.

Other genetic factors ? not identified in the new study ? determine what kind of head crest east pigeon develops: shell, peak, mane or hood, according to Shapiro.

Tracking the Origins of Pigeons

A 2012 by Shapiro study provided limited evidence of pigeons' origins in the Middle East and some breeds' origins in India, and indicated kinship between common feral or free-living city pigeons and escaped racing pigeons.

In the new study, "we included some different breeds that we didn't include in the last analysis," Shapiro says. "Some of those breeds only left the Middle East in the last few decades. They've probably been there for hundreds if not thousands of years. If we find that other breeds are closely related to them, then we can infer those other breeds probably also came from the Middle East. That's what we did."

"We found that the owl breeds ? which are pigeon breeds with very short beaks and that are very popular with breeders ? likely came from the Middle East," he says. "They are very closely related to breeds we know came from Syria, Lebanon and Egypt."

Shapiro says the study also "found a lot of shared genetic heritage between breeds from Iran and breeds we suspect are from India, consistent with historical records of trade routes between those regions. People were not only trading goods along those routes, but probably also interbreeding their pigeons."

As for the idea that free-living pigeons descended from escaped racing pigeons, Shapiro says his 2012 study was based on "relatively few genetic markers scattered throughout the genome. We now have stronger evidence based on 1.5 million markers, confirming the previous result with much better data."

The scientists analyzed partial genomes of two feral pigeons: one from a U.S. Interstate-15 overpass in the Salt Lake Valley, and the other from Lake Anna in Virginia.

"Despite being separated by 1,000 miles, they are genetically very similar to each other and to the racing homer breed," Shapiro says.

He notes that pigeons were one of evolutionist Charles Darwin's "favorite examples of how selection works. He used this striking example of artificial selection [by breeding] to communicate how natural selection works. Now we can get to the DNA-level changes that are responsible for some of the diversity that intrigued Darwin 150 years ago."
