Security—for the information on your smart phone, as well as for the phone itself—is a hot topic these days.The truth is that you're packing a lot of sensitive information on your phone, and you should keep it safe.

    When it comes to physical security, iPhone users would do well to download Find My iPhone, a free app from Apple that allows you to visit a website and see your (lost, stolen or misplaced) phone on the map.You can then sound an alarm, send a message that will pop up on its screen, lock the phone or erase all your data.

    Android does not have an exact equivalent(等价物), but there are plenty of alternatives. A free app called Lookout offers the find­my­phone feature.The paid version allows you to wipe the data from your phone remotely.

    Then there is your coffee shop's Wi­Fi network.Anyone with minimal technical expert skill can snoop on(窥视) people using shared wireless networks, harvesting passwords and other personal data. Lookout will caution you when you've logged on to an insecure network, but cannot protect you once you're there.

    In order to protect yourself on such networks, you can use a virtual private network, or VPN. This turns all your activity into nonsense to anyone trying to read along with you from across Starbucks. It also keeps websites from tracking you and, if you're travelling, allows you to get access to sites that may be blocked in other countries.

    If you have an iPhone, the simplest VPN app is probably Hotspot Shield, whose distinguishing feature is said to be that it automatically kicks in each time you start browsing (浏览), as opposed to other VPN apps that require you to start them up manually(手动地)．This matters, because even if you decide you want a VPN app, you want to spend approximately zero time thinking about it. For the most part, that was true of Hotspot Shield, though occasionally it took a while to connect or temporarily lost connection without warning. I found myself having to turn the app on and off sometimes, which involved setting my phone constantly.

    If even reading about the settings on your phone drive you crazy, then it is probably best to stay away from a VPN app. But if you're the type who can't resist checking your bank balance from your corner bar, the hassle(麻烦) may be preferable to the risk.

    Nearly all of us have a bad habit, whether we know it or not. Some people say they want to get rid of (去除) it but don't know the proper ways. Here's some advice on how to get rid of bad habits.

    Make a list. Write down all the reasons why you want to stop a certain behavior, how it's hurting you and why to get rid of it, this will help a lot. Look at that list regularly.

    Join in other activities. It's wise of you to do something else when you want to stop your bad habit. If you get angry easily, for example, you can practice having a deep breath or going for a walk.

    Give yourself a present. Before you take action against a bad habit, decide what you'll do to celebrate it if you reach your goal.

    Keep off bad habits. If you are fat and want to lose weight, keep junk food out of your house. If you are a heavy smoker with coffee, turn to tea and keep away from friends who like smoking.

    Be patient. Bad habits develop over years, so you probably won't be able to get rid of them quickly. In fact, people often give up several times before being successful, so you should be patient.

    Find support. Don't be afraid to ask for support from friends, family or other people who have the same bad habits as you. When you talk to others, they might be able to provide advice or encouragement that you usually wouldn't get from yourself.

    Miles was born in Alton, a city on the Mississippi River in Illinois on May 26, 1926. Miles's father was a dentist, while his mother was a music teacher. Miles had a good childhood, catching fish and riding horses with his older sister and younger brother. He was known as a naughty boy in school.

    He recalls his story, “By the age of 12, music had become the most important thing in my life.” His mother, a violinist herself, dearly wanted her son to play the violin. But brass (铜管) was Miles's calling, and he remembers arguments between their parents as his dad overruled her to fight his son's corner. He received his first trumpet (喇叭) in 1935 and began weekly music lessons with his father's friend Mr. Elwood, his life-long teacher.

    Talking about his school days, Miles said that Mr. Buchanan was the biggest influence on his life. He was the person who took Miles all the way into music at that time. He wanted to be a musician that he had dreamed.

    When he was 16, Miles met his girlfriend, Irene Birth. Although she was a beautiful young woman in many ways, it was her easy-going character that attracted Miles. At the weekends, Miles and Irene would take the bus over the Mississippi River to St Louis to watch movies and go dancing. Although Miles was too shy to really enjoy dancing, he always felt confident when he danced with Irene.

    When he turned 17, she persuaded him to ask for a job in his band—Eddie Handle's Blue Devils. It worked. Joining the band was a breakthrough for Miles, and marked the time when he first began to write and arrange music.

    Shoppers in the UK are spending less money on toilet paper to save money, research has shown.

    Penny saving UK consumers choose cheaper products from discounters such as Aldi and Lidi rather than expensive alternatives.

    This has wiped 6% off the value of the soft tissue paper market in the UK. It has reduced from £1.19 billion in 2011 to £1.12 billion in 2015, according to a new report from market research company Mintel. Furthermore, the future of the market looks far from positive, with sales expected to fall further to £1.11 billion in 2016.

    In the last year alone, despite an increase in the UK population and a rise in the number of households, sales of toilet paper fell by 2%, with the average household reducing their toilet roll spending from £43 in 2014 to £41 in 2015.

Overall, almost three in five people say they try to limit their usage of paper – including facial tissue and kitchen roll    to save money. “Strength, softness and thickness remain the leading signs of toilet paper quality, with just a small part of consumers preferring more expensive alternatives, such as those with flower patterns or perfume,” said analyst Jack Duckett. “These extra features are considered unnecessary by the majority of shoppers, which probably reflects how these types of products are typically more expensive than regular toilet paper, even when on special offer.”

    While consumers are spending less on toilet paper, they remain particular about it when it comes to paper quality. One in 10 buyers rank toilet rolls made from recycled paper among their top considerations, clearly showing how overall the environment is much less of a consideration for shoppers than product quality. In a challenge for makers, 81% of paper product users said they would consider buying recycled toilet tissue if it were comparable in quality to standard paper.

    As an old saying in China goes, "The days of the Sanjiu period are the coldest days." "Sanjiu period", which is in Minor Cold, refers to the third nine-day period (the 19th to the 27th day) after the day of the Winter Solstice (冬至). There are many different customs related to Minor Cold in China.

    Eating hotpot

    During Minor Cold people should eat some hot food to benefit the body and defend against the cold weather. Winter is the best time to have hotpot and braised mutton with soy sauce. But it is important to notice that too much spicy food may cause health problems.

    Eating huangyacai

    In Tianjin, there is a custom to have huangyacai, a kind of Chinese cabbage, during Minor Cold. There are large amounts of vitamins A and B in huangyacai. As huangyacai is fresh and tender, it is fit for frying, roasting and braising.

    Eating glutinous rice (糯米饭)

    According to tradition, the Cantonese eat glutinous rice in the morning during Minor Cold. Cantonese people add some fried preserved pork, sausages and peanuts and mix them into the rice.

    Eating vegetable rice

    In ancient times, people in Nanjing took Minor Cold quite seriously, but as time went by, the celebration of Minor Cold gradually disappeared. However, the custom of eating vegetable rice is still followed today. The rice is steamed and is unspeakably delicious. Among the ingredients (原料), aijiaohuang (a kind of green vegetable), sausages and salted duck are the specialties in Nanjing.

Socially, few things are more annoying than someone repeatedly checking their phone in the middle of your conversation with them. Soon enough, you're having unhappy thoughts, thinking of their way like, I'm boring you; you're more concerned with whoever's on that phone than me; you don't care about me. None of that is necessarily true, but this is: "If someone is engaged in a great conversation, they wouldn't care about their phones," says Leslie, a psychologist and researcher at NYU.

Do you sometimes wonder: What should I have said to a rude person like this? What if we have to talk to such maddening persons? Experts have advice about how to deal with this.

Whether you say something or not, remember that the cell-addict's annoying habits aren't about you. "It's rude, for sure, but sometimes we mistake the behavior for more than what it is," says Leslie. "It's possible that they are facing something tough and merely experiencing nervousness or anxiety," he adds. It's also possible that their partner is stuck with a flat tyre (轮胎) or their kid is sick in hospital. The point is that you don't know.

So before you become angry at the cell-addict's open rudeness, focus instead on building a better conversation than whatever's going down on Instagram. You might never be able to achieve this, given the power of today's social media, so if you're close enough to a person, Leslie advises you to directly ask them: "What's on that thing that's so interesting?" Chances are that they will apologise at once and quickly put the phone away. But if the answer is something real, talk about it. Better yet, you can avoid the situation in advance by saying something like, "I'm really interested in catching up properly, so how about we leave our phones in the car?" If they indeed have that flat tyre or sick kid, at least you won't have to assume that it's because your stories are boring.
