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.

    Persuasion is the art of convincing someone to agree with you. According to the ancient Greeks, there are three basic tools of persuasion : ethos, pathos, and logos.

    Ethos is a speaker's way of convincing the audience that she is trustworthy, honest and reliable. One common way a speaker can develop ethos is by explaining how much experience or education she has in the field. After all, you're more likely to listen to advise about how to take care of your teeth from a dentist than a fireman. A speaker can also create ethos by convincing the audience that she is a good person. If an audience cannot trust you, you will not be able to persuade them.

    Pathos is a speaker's way of connecting with an audience's emotions. For example, a politician who is trying to convince an audience to vote for him might say that he alone can save the country from a terrible war. These words are intended to fill the audience with fear, thus making them support him. Similarly, an animal charity might show an audience pictures of injured dogs and cats, to make the viewers feel pity. If the audience feels bad for the animals, they will be more likely to donate money.

    Logos is the use of facts, statistics, or other evidence to support your argument. An audience will be more likely to believe you if you have convincing data to back up your claims. Presenting this evidence is much more persuasive than simply saying “believe me”.

    Although ethos, pathos, and logos all have their strengths, they are often most effective when used together. Indeed, most speakers use a combination of ethos, pathos, and logos to persuade their audiences. So, the next time you listen to a speech, watch a commercial, or listen to a friend try to convince you to lend him some money, be on the lookout for these ancient Greek tools of persuasion.

    Daniel was born in New Orleans, LA., in 1962, slow to walk and talk, and short. He was the tiniest in his class, but he developed a warm, outgoing nature and was popular with his peers(同龄人). And he became skillful at sports.

    Baseball gave him his earliest challenge. He was an excellent players in Little League. At graduation, the coach named Daniel the team's most valuable player.

    His finest hour, though, came at a school science meeting. He entered an exhibit explaining how the circulatory system works. It was traditional, especially compared to（与…相比）the modern, computerized, blinking-light models entered by other students. My wife, Sara, felt embarrassed for him.

    It turned out that the other kids had made their exhibits. As the judges went on their rounds, they found that these other kids couldn't answer their questions. Daniel answered every one. When the judges awarded the Albert Einstein Plague for the best exhibit, they gave it to him.

    By the time Daniel left for college he stood six feet tall and weighed 170 pounds. He was in superb condition, but he quit baseball for English literature. I was sorry that he would not develop his athletic talent, but proud that he had made such a satisfactory decision.

    One day I told Daniel that the great failing in my life had been that I didn't take a year or two off to travel when I finished college. This is the best way, to my way of thinking, to broaden oneself. Once I had married and begun working, I found that the dream of living in another culture had disappeared. Daniel thought about this. After graduation, he worked as a waiter at college, a bike messenger and a house painter. With the money he earned, he had enough to go to Paris.

    The night before he was to leave, I tossed in bed. I was trying to figure out something to say. Nothing came to mind. Maybe, I thought, it wasn't necessary to say anything.

    They aren't great artists like Leonardo da Vinci or Vincent van Gogh, but their paintings are just as popular on Chinese social media, with millions of Chinese people willing to pay for them.

The 36 works were painted by ordinary Chinese people who live with autism (自闭症) or cerebral palsy (脑瘫), aged from their early teens to late thirties. They all studied art at World of Art Brut Culture (WABC), which is a Shanghai-based non-profit organization (非赢利组织) for art education. The project was started by WABC and supported by the Tencent Charitable Foundation. Users could buy a digital copy of each painting by donating (捐赠) 1 yuan or more. By Aug 29, donations totaled more than 15 million yuan, with about 5.8 million people participating (参与).

    “The paintings by these autistic kids and adults are beautiful: the style is similar to that of the Dutch artist Van Gogh. I'm really impressed by their talent,” Feng Li, a customer service officer in Shanghai, told the South China Morning Post.

    However, the popular campaign also led to certain questions.

    Li Laoxi, an experienced special education teacher in Hangzhou, said that based on his experience, people with autism could only draw a few lines or fill in colors under the guidance of their trainers. “Maybe there are some geniuses out there, but I've never met them”. Others questioned where the money would go, as the donations went to WABC instead of the painters. In response to these concerns, Miao Shiming, founder of WABC, said the money would be used to employ art teachers, buy supplies, and rent facilities. Meanwhile, Tencent said that all donation information would be open to the public.

    Some people think that success is only for those with talent or those who grow up in the right family, and others believe that success mostly comes down to luck. I'm not going to say luck, talent, and circumstances don't come into play because they do. Some people are born into the right family while others are born with great intelligence, and that's just the reality of how life is.

    However, to succeed in life, one first needs to set a goal and then gradually make it more practical. And, in addition to that, in order to get really good at something, one needs to spend at least 10,000 hours studying and practising. To become great at certain things, it'll require even more time, time that most people won't put in.

    This is a big reason why many successful people advise you to do something you love. If you don't enjoy what you do, it is going to feel like unbearable pain and will likely make you quit well before you ever become good at it.

    When you see people exhibiting some great skills or having achieved great success, you know that they have put in a huge part of their life to get there at a huge cost. It's sometimes easy to think they got lucky or they were born with some rare talent, but thinking that way does you no good, and there's a huge chance that you're wrong anyway.

    Whatever you do, if you want to become great at it, you need to work day in and day out, almost to the point of addiction, and over a long period of time. If you're not willing to put in the time and work, don't expect to receive any rewards. Consistent, hard work won't guarantee you the level of success you may want, but it will guarantee that you will become really good at whatever it is you put all that work into.

    My elephant adventures began in 1984 when, with our one-year-old daughter, my husband and I crossed the jungle in a jeep, slicking behind a lorry for comfort and company. The elephants standing like watchers on either side of the forest highway had us praying for our safety. One elephant made loud noise and angrily pawed (抓) the ground, warning us off. We raced away before they could attack.

    It was wise to keep elephants at a distance. We heard stories of tourists whose jeeps were overturned, and a couple of photographers were killed because they moved too close. Elephants are misleading animals. They give people an impression of being quiet and kind, so tourists think it's safe to picnic in the jungle (丛林). Yet angry elephants have knocked them down in seconds before they could take off.

    Elephants might make life unpredictable and dangerous. It's difficult for inexperienced environmentalists to even, begin to grasp this reality. I've heard city people say " We humans are encroaching (侵害) on their forests." But what's the solution?

    When a poor farmer borrows heavily to plant a crop, he'll do anything to protect it His life depends on it Elephants ruining an about-to-be-harvested corn field cannot expect to be welcomed like special guests. The battle between beast and farmer is violent.

    Experts are working on solutions to human-elephant conflicts (冲突). Some are sure to fail to like the plans to build electric fences around human settlements. Elephants rapidly figure them out and come in, around and over them.

    There are more questions than answers, for sure. But as my husband said, "More people die in car accidents every single day, in every city on the earth. But they won't take cars off the roads, will they?" So we need to seek practical ways of preventing elephant accidents.
