With brown curly hair and a pair of glasses, 19-year-oldNicholas Allegra from New York state, US, looks like a real-life Harry Potter.However, rather than waving a wand, Nicholas is a "wizard " at"jailbreaking ". This is probably why he ended up with an intern­shipat Apple, a job many of his fellow Brown University students dream of.

Jailbreaking is the process of removing the limitations set byApple on devices with the iOS oper­ating system. These devices include theiPhone, iPod Touch, and iPad. It allows users to gain full access to theoperating system and download additional materials that are unavailable through the official Apple App Store.However, it is estimated that Apple loses $100 million (640million yuan) fromjailbreaking each year.

Nicholas, with a famous nickname "Comex", is theteenage hacker behind the jail-breaking site JailbreakMe. com. The site tellsusers how to unlock their iPhones using software that is not approved by Apple.The jailbreaking software he made has been downloaded millions of times byusers around the world.

Then Forbes magazine suggested in an article that Apple's securityteam might need him as a new intern. It seems that they do. Little more than aday after Steve jobs stepped down as CEO, Apple welcomed Nicholas Allegra.Nicholas wrote on his Twitter on August 26 that " It's been really, reallyfun, but it's also been a while and I've been getting bored. So, the week afternext I will be starting an internship with Apple.

Apple is not the only company embracing the skills ofhackers. Facebook recently hired iPhone jailbreaker George "Geohot"Hotz as a full-time employee.

However, there are still hot debates about whether employinghackers is a wise solution. The word "hacker" has always had a doublemeaning. In the press, "hacker" means someone who breaks intocomputers. They steal from people's bank ac­counts, download sensitiveinformation and attack legal websites. Among computer lovers, it means a coolpro­grammer who can make a computer do whatever he wants.

Hiring a hacker does have its advantages. A talented hacker isprobably quite capable of finding problems and suggesting corrections. On theother hand, because of a hacker's former behavior, many people doubt theirmorals .Can the company trust them with its valuable assets ? And can someonewho is so used to working alone in the dark fit into a new role within acompany?

One thing is for sure- Comex isn't the first member of thehacker community to land the job of his dreams. It's likely that he won't bethe last.

    A team of engineers at Harvard University has been inspired by Nature to create the first robotic fly. The mechanical fly has become a platform for a series of new high-tech integrated systems. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.

    “It's extremely important for us to think about this as a whole system and not just the sum of a bunch of individual components (元件),” said Robert Wood, the Harvard engineering professor who has been working on the robotic fly project for over a decade. A few years ago, his team got the go-ahead to start piecing together the components.“The added difficulty with a project like this is that actually none of those components are off the shelf and so we have to develop them all on our own,” he said.

    They engineered a series of systems to start and drive the robotic fly. “The seemingly simple system which just moves the wings has a number of interdependencies on the individual components, each of which individually has to perform well, but then has to be matched well to everything it's connected to,” said Wood. The flight device was built into a set of power, computation, sensing and control systems. Wood says the success of the project proves that the flying robot with these tiny components can be built and manufactured.

    While this first robotic flyer is linked to a small, off-board power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gathering work at rescue sites, in farmers' fields or on the battlefield. “Basically it should be able to take off, land and fly around,” he said.

    Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board could have much broader applications. “You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animals, but using these robots instead,” he said. “So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day to day basis.”

    Reading can be a social activity. Think of the people who belong to book group. They choose books to read and then meet to discuss them. Now the website BookCrossing.com turns the page on the traditional idea of a book group.

    Members go on the site and register the books they own and would like to share. BookCrossing provides an identification number to stick inside the book. Then the person leaves it in a public place, hoping that the book will have an adventure, traveling far and wide with each new reader who finds it.

    Bruce Peterson, the managing director of BookCrossing, says, “The two things that change your life are the people you meet and books you read. BookCrossing combines both.”

    Members leave books on park benches and buses, in train stations and coffee shops. Whoever finds their book will go to the site and record where they found it.

    People who find a book can also leave a journal entry describing what they thought of it. E-mails are then sent to the BookCrossers to keep them updated about where their books have been found. Bruce Peterson says the idea is for people not to be selfish by keeping a book to gather dust on a shelf at home.

    BookCrossing is part of a trend among people who want to get back to the “real” and not the virtual(虚拟). The site now has more than one million members in more than one hundred thirty-five countries.

    Most students, when asked about their best graduation(毕业) gift, would probably reply, “ A car”, or “Money for a house”. Cai Kaiyuan, 21, made a difference choice. As a graduation gift to himself, he decided to work as a volunteer teacher in a distant village in Tibet.

    Cai, a student at Huan Railway Professional Technology College, at first planned to cycle from Sichuan to Tibet. It turned out cycling on a plateau(高原) was quite difficult. And it has kept changing his opinion on life. Cai's hands even became painful while cycling up a 5008-meter-high mountain, where temperatures often dropped to 18 below zero. At night, the ice covered the road and he fell off his bike three times. Little oxygen made him feel sick and weak. “At the most serious moment, I felt that was on the line,” said Cai.

    However, he also gained something unexpected. At Ya' an, a city in Sichuan, he met a group of tourists who are also university students. A girl called Wu Ling told him that she planned to work as a in a primary school in Tibet after her journey. He was impressed by the idea as she looked weak.

    It was not until he reached a family-run hotel in Shigatse that Cai's spirits began to rise. The hotel manager's two daughters enjoyed talking with him. The kids asked about his experiences on his trip, and showed him the beautiful local lakes. “They told me that they always liked to talk to guests, as they wanted to improve their Mandarin,” he said, “Their parents and many locals can only speak Tibetan.”

    Cai was moved by the girls' story. Their situation is worse and the local people have little chance to learn Mandarin because the schools are short of teacher. “1 want to do something to improve the situation for kids like them,” said Cai. His parents finally gave their agreement and his teachers also supported him.

Half a Day

    I walked alongside my father, holding his right hand. All my clothes were new: the black shoes, the green school uniform, and the red cap. They did not make me happy, however, as this was the day I was to be thrown into school for the first time.

    "Why school?" I asked my father. "What have I done?"

    "I'm not punishing you," he said, laughing. "School's not a punishment. It's a place that makes useful men out of boys. Don't you want to be useful like your brothers?"

    I was not convinced. I did not believe there was really any good to be had in tearing me away from my home and throwing me into the huge, high-walled building.

    When we arrived at the gate we could see the courtyard, vast and full of boys and girls. "Go in by you," said my father, "and join them. Put a smile on your face and be a good example to others."

    I hesitated and squeezed his hand firmly, but he gently pushed me from him. "Be a man", he said. "Today you truly begin life. You will find me waiting for you when it's time to leave."

    I took a few steps. Then the faces of the boys and girls came into view. I did not know a single one of them, and none of them knew me. I felt I was a stranger who had lost his way. But then some boys began to glance at me in curiosity, and one of them came over and asked, "Who brought you?"

    "My father," I whispered.

    "My father's dead," he said simply.

    I did not know what to say. The gate was now closed. Some of the children burst into tears. The bell rang. A lady came along and said, "This is your new home. There are mothers and fathers here, too. Everything that is enjoyable and beneficial is here. So dry your tears and face life joyfully."

    Well, it seemed that my misgivings had had no basis. From the first moments I made many friends. I had never imagined school would have this rich variety of experiences.
