Google, one of the world's outstanding tech companies, was attacked. It wasn't its search engine that was attacked or its advertising platform or even its social network. Google⁺. Instead, it was a building.

    Two web security experts hacked (侵入) into its Wharf 7 office in Sydney, Australia, through Google's building management system (BMS). One of them, Billy Rios, says, “My colleague and I have lot of experience in web security, but it is not something that people couldn't learn. Once you understand how the system works, it is very simple.

    They found the system on Shodan, a search engine that lists devices connected to the Internet, and then ran it through their own software to identify who owned the building. In the case of the Google hacking, the researchers had no immoral purpose and just informed Google about what they found.

    According to Mr Rios, who runs security company Whitescope, there are 50, 000 buildings currently connected to the Internet, including research institutes, churches and hospitals, and 2, 000 of those are online with password protection, Martyn Thomas, a professor of IT at Gresham College in the UK, says, “It is beyond doubt that attempts to attack building management systems are happening all the time.”

    Making a building smart generally means connecting the systems that control heating, lighting and security to the Internet and the wider corporate network. There was a strong reason for doing this, said Andrew Kelly, principal security consultant at defence company Qinetiq.

    “Energy savings are the biggest factor in connecting building management systems to the corporate network,” he says. “It gives those who run the building better control and offers between 20% to 50% in energy savings,” he adds.

    But it also makes them less secure. And if any of these feels like a Hollywood filmy, think again.

    In the past, people who graduated from college felt proud of their academic achievement and confident that their degree would help them find a good job.

     However, in the past four years the job market has changed dramatically. This year's college graduates are facing one of the worst job markets in years. For example, Ryan Stewart, a graduate of San Jose University, got a degree in religious studies, but no job prospects. He points out that many people already working are getting laid off and don't have jobs, so it's even harder for new college graduates to find jobs.

    Four years ago, the future looked bright for the class of 2013. There were many high-tech job opportunities. Graduates received many job offers, and they were able to get jobs with high salaries and benefits such as insurance and paid vacations. However, “Times have changed and it's a new market,” according to Cheryl Allmen- Vinnidge of the San Jose State Career Center.

    Allmen-Vinniage says students who do find jobs started preparing two years ago. They worked during summer vacations, they have had several internships（实习）, and they have majored in one of the few fields that are still hot, like chemical engineering, accounting, or nursing, where average starting salaries have actually increased over last year. Other popular fields (like information system management, computer science, and political science) have seen big reduction in starting salaries.

    Ryan Stewart (he had hoped to become a teacher) may just end up going back to school. “I'd like to teach college some day and that requires more schooling, which would be great in bad economy.” he said.

    In conclusion, these days, to some students a degree may not be a ticket to instant wealth. For now, they can only hope its value will increase over time.

    Most advertising in ancient times was word-of-mouth, that is, people liked something and told others about it. But even then, people advertised by putting inscriptions (题字) on walls, for example to display political slogans and to offer household goods for sale. Also, in Rome and Greece, in ancient times, it was common for people to use papyrus, a kind of paper, to advertise things they had lost or found. The tradition of wall or rock painting as a way of advertising goods is even more ancient.

    Painting developed in the 15th and 16th centuries, and this increased the forms of advertising. Handbills — small printed notices and advertisements — became common. Then, by the 17th century, advertisements started appearing in weekly newspapers in England. In the 19th century mail order catalogues appeared, promoting all kinds of goods.

    Finally, advertisements in the 1960s became more creative and more interesting. Also, they began to draw attention to the 'unique selling points', the USPs of products. These are the qualities that make a product different from competitors' products.

    These days, advertisers have come up with new ways of promoting their products. For example, product placement is now common. This is advertising in TV programmes or films by having a character, preferably played by a famous actor, use a particular product. For example, Tom Cruise's character in the movie, Minority Report, had a computer with the Nokia logo (商标) on it, and his watch was clearly made by Bulgari.

    TV commercials are a very effective medium for advertisers, though these are very expensive. If an organization wants to have a 30-second TV advert during the annual Superbowl game in the United States, they have to pay about $2.5 million.

    Perhaps the most interesting development is the use of famous personalities to endorse (代言) a product. The basketball player, Michael Jordan, endorsed Nike products and wore them while playing.

    Getting well-known personalities to endorse a product can be very expensive, but endorsements certainly increase a product's sales, especially if the personality has a positive image in the eyes of the public.

    Jane Austen has often been considered a woman who led a narrow, inhibited life and who rarely traveled. These assertions are far from the truth. Jane Austen traveled more than most women of her time and was quite involved in the lives of her brother, so much that it often interfered with her writing. Like most writers, Jane drew on her experiences and her dreams for the future and incorporated them into her writing. Her characters reflect the people around her; the main characters reflect parts of herself. In Sense and Sensibility and Pride and Prejudice, Elinor Dashwood and Elizabeth Bennet reflect aspects of Jane Austen and dreams she had that were never fulfilled.

    The biographies about Jane Austen describe the facts of her life in a step-by-step manner. They tend to be repetitive since she did not leave behind a rich fabric of day-to-day life. Yet Jane Austen is known not because of the factual details of her life; she is not remembered two hundred years after her death because she had six siblings and was a wonderful aunt to her nieces and nephews. Rather, Jane Austen is remembered because of what she wrote. Only through reading her literature does one get a taste of the real Jane Austen, the Jane Austen who dreamed and made plans for the future that failed to materialize. Only by analyzing June Austen's characters do we get an understanding of the true author.

    Sense and Sensibility's Elinor Dashwood mirrors Jane Austen's strait-laced sense of propriety (礼节) and her concern and care about family members. For example, after her father died, Jane managed to gather herself together and send her father's pocket compass and pair of scissors to her brother Frank as a memento of their father. Elinor in Sense and Sensibility is the sister who holds down the family and discusses the practicality of situations. She too distributes cherished mementos of her father when he dies. Elinor is the sister who is concerned with the welfare of her relations and takes it upon herself to look after their well-being.

    Jane can also be considered the backbone of her family. After she dies, the family is not as close as they were during her lifetime. Jane became very close with two of her nieces, Fanny Austen and Anna Austen. She counseled them on men and marriage when they reached the age of choosing a suitor. She often helped with delivering her sister-in-law's babies. During her thirties, she lived with her brother Frank for several weeks. She cooked the meals for his family and cared for his children while his wife was confined to her bed. Like the character she creates in Elinor, she sticks by her family and helps them when they need her.

    Austen's life closely parallels that of Elizabeth Bennet in Pride and Prejudice. Austen begins the novel with the line, “It is a truth universally acknowledged that a single man in possession of a good fortune must be in want of a wife”. This statement reflects the opinion of the time that a woman had to be married or else she had no social standing. Just as Elizabeth and her sisters feel immense pressure to get married and procure a good match, so too did Jane. Until she was twenty-five she still retained a small spark of hope that she would one day marry and have children.

    The most significant similarity between Jane and Lizzy is their close relationships with their sisters. Jane and her sister Cassandra were extremely close. When they moved into a house in Chawton, they shared a bedroom. They were dependent upon each other and supported each other in all aspects of their lives. They supported each other's decisions and wrote to each other when apart. Lizzy and her older sister Jane were extremely close. They too supported each other's decisions and were always there for the other. They discussed suitors and marriage just as Jane and her sister must have done.

    All of Jane's female characters end up happily married, a state Jane herself never felt. A woman was defined in terms of her husband; if she did not marry, she had nothing. Well into her twenties, Jane still had dreams of getting married. When she was twenty-five, Harris Bigg-Wither, a brother of her good friends, proposed marriage to Jane. At first she accepted: she would become mistress of a large estate, and be able to ensure the comfort of her parents to the end of their days. Most importantly, she would have children and raise a family of her own. The next day, however, Jane reneged the proposal. She did not love him and did not want a marriage based on nothing but money. After this proposal, Jane gave up all hopes of ever having a family of her own. Instead, she fulfilled her dreams through her characters and found “passion” through them. All her characters marry for love (which happens to also be financially advantageous). They make Jane's dreams become a reality within her imagination. _____ . As children reflect upon the parents and often mirror aspects of their parents, so too did many of Jane's characters mirror herself and the people around her.

    Though pigs may never fly, a two-year-old pig in Franschhoek, South Africa is proving they sure can paint! Meet Pigcasso, the world's first known pig artist whose masterpieces are selling for thousands of dollars to benefit Farm Sanctuary S. A. , Africa's only registered shelter for rescued farm animals.

    Joanne Lefson, who saved Pigcasso from a slaughterhouse(屠宰场) two years ago, discovered the animal's artistic talent accidentally. The South African activist says, of the numerous toys presented to keep the then four-week-old piglet entertained, it was the paintbrushes that seemed to attract her the most. "They were the only thing she didn't eat," Lefson quips.

    The rescuer decided to present the pig with canvas and paint and see what happened. To her delight, Pigcasso began creating works of art that can best be described as "abstract expressionism". Now weighing a hefty(重量）450 pounds, the celebrated pig, who loves to paint the area's scenic landscapes, has a dedicated "studio" at Farm Sanctuary S.A. where she resides. Lefson says, "I do not force her to paint. She paints when she wants to."

    Pigcasso's artwork, which has thus far been sold online, is currently on display at Cape Town's picturesque Victoria ~ Alfred Waterfront. Dubbed "Oink", the pop-up exhibition will run through March 5before heading to London-Paris-Berlin, and Amsterdam. Lefson says its main aim is to highlight the effect of animal agriculture on the planet and inspire change.

    While Pigcasso is the first pig and first nonhuman to headline an exhibition, she is not the first animal to create masterpieces. Elephants, sea lions, and even penguins have shown similar artistic talent--in exchange for some treats, of course!

    Moving flight times from night to day could reduce air travel's contributions to global warming, a new study suggests. Scheduling more (lay time flights may reduce the influence of contrails ——the visible lines of white steam that many planes leave behind them in the sky.

    The role of contrails in climate change is still being studied, but some scientists believe they contribute to the greenhouse effect by trapping heat in the atmosphere.

    Nicola Stuber, first author of the study, suggests that contrails' overall impact on climate change is almost as big as that of aircraft^? s carbon dioxide emissions (排放)over a hundred-year period. Aircraft are believed to be responsible for 2-3% of human carbon dioxide emissions. Like other high, thin clouds, contrails reflect sunlight back into space and cool the planet. However, they also trap energy in the atmosphere and increase the warming effect.

    Stuber and other scientists believe that the effect of the contrails is big. "On average, the green-house effect controls the effects of contrails, said Stuber, a meteorologist at England's University of Reading." The warming effect is far greater for contrails left by night flights," Stuber added. "The cooling effect only happens (luring the day when the sun is up. During the night the greenhouse warming is no longer balanced and that is why the contribution of night-flight is so large."

    Most commercial airline traffic occurs during daylight hours. For example, only one in four United Kingdom flights is a night flight, but those flights create some 60% of the warming created by contrails, the study reports.
