China's largest search engine Baidu has said it will make its latest artificial intelligence (AI) technology accessible to developers and businesses as part of the company's latest move into AI, big data and cloud computing.

    AI solution "Tianzhi" was launched at a cloud-computing summit held in Beijing Wednesday. It includes services in three fields: sensing technology, such as image and voice processing, machine learning, and deep learning, an advanced form of machine learning, said Zhang Yaqin, CEO of the Nasdaq-listed company, at the summit.

    Developers can access facial or voice recognition, algorithms(演算法) for data analysis and projections, and deep learning applications, Zhang said, adding that the technology could help users innovate in their sectors.

    "With more devices connected to the cloud, enterprises will use cloud computing and AI more frequently," said Wu Hequan, an academician at the Chinese Academy of Engineering, "Open AI technology can play a bigger role."

    The company also revealed a plan to invest 10 billion yuan (1.45 billion U.S. dollars) in cloud computing in the next five years and establish an innovation center, which will serve 10 million enterprises.

    China is the biggest market in the world, and many countries such as Germany, the USA, the UK and Russia do a lot of business in China. Let's have a look at some important tips to help you be successful when dealing with these nationalities.

    First, you must be punctual (准时的) with Germans. Even 5 minutes late makes a bad impression. Being punctual is also very important in the USA. In the UK, it's important to be punctual for business meetings, but nobody expects you to be on time for a social event. Half past seven really means a quarter to eight, or even eight o'clock! With Russians, you should always be on time, though it is not unusual for them to be one or even two hours late!

    It is best to dress formally and wear dark colours when you meet people from all the four countries. In Russia, designer clothes are very common. Don't be surpri if you go to an office in the UK on a Friday and find everyone wearing jeans. Many companies have “dress down Friday”, when people wear casual (随便的) clothes.

    In Germany, first names are only used by family members and close friends, so be prepared to use titles and last names. In the USA you will usually be invited to use first names almost immediately. The British are quite informal and using first names in business is more and more common, especially among younger people. In Russia, however, nobody uses first names, so use titles and last names.

    In conversation, the British and the Americans value humour, and both like to talk about sport. The weather is also a good topic of conversation with the British and the Americans, but avoid talking about politics. In Russia, say positive（肯定的） things about their country, but avoid making complaints. The Germans, however, prefer to get straight down to business!

    So, use these tips, and you will be on your way to a successful international business career!

    Augusto Esquivel is a sculptor who, in his own words, is “crazy with comparisons of reality and potential and the balance between them.” Perhaps the best example of what he's talking about are his most famous creations: the suspended(悬挂的) button sculptures.

    Made entirely from buttons hanging on various lengths of string, Esquivel's sculptures are made to look like common objects: a piano, a gumball machine, and even a toilet. If it wasn't for the clear string hanging above, these objects, these sculptures, would look solid, yet you can put your hands right through them. The process starts with him deciding on a subject and setting the acrylic （丙烯酸树脂）from where the buttons are being suspended. He buys buttons of different shapes and sizes, paints them with spray paint, and carefully hangs them. After that, it's a manner of hanging each individual button, which takes a lot of time. For his piano, for example, he individually hung over 60 pounds worth of tiny buttons.

    Esquivel's sculptures, while mostly housed inside art galleries, perfectly capture one of the main principles of street art: something that is eye-catching and something that invites interaction. Often the best sculptures outside the art galleries aren't the ones behind guards and fencing, but the ones people can go right up to and touch. In Vancouver, a series of laughing old men are attracting people for pictures and to just generally hang around, but the people who simply walk by and see the sculptures almost always leave with a smile on their face. That's good street art: it draws the viewer in rather than relying on a gallery to draw in an audience and point them to certain pieces.

    Esquivel's art is not only a presentation of talent, something that mentions larger philosophical questions, like the ones he stated above, but also just the right combination of interesting idea and painstaking work. One can look at his work in a critical way, or simply appreciate his idea and execution(艺术品的制作).

    When my son was about five or six, I traveled a lot on business. I worried all the time about what the absence might mean to him. I knew how important it was for a boy to have his father near. When I was small, the times I loved most were the special moments I shared with my father. I cherished these special moments and, to this day, hold those memories dear. I decided to create those kinds of special times for my son.

    In one of my letters home, I promised my son that I would teach him how to fly a kite and that we could go to a nearby beach and fly it as high as it would go. Through my travels I would pick up things for our kite adventure and send them to him. In my trip to Japan, I found the most beautiful blue silk with gold threads（线）woven through it. Perfect kite materials! I sent it home with a picture book that would serve as a weight.

    When I got home at night, I found him sleeping sound, surrounded by all the items I had sent him for our kite. For the next week, we started to work on our masterpiece. We had our time together in the garage, after dinner. Finally, it was finished. The blue silk made it so beautiful. He was obviously eager to fly it soon. “We'll fly it tomorrow, right, Dad?” “Yes, if the weather is right,” I explained that we needed wind to lift the kite off the ground. I was afraid that it might rain. “We'll fly it because I'm going to pray with all my heart for the best kite weather.” He was right. I will never underestimate（低估）the power of a child's prayer any more.

    My son is a dad now, with children of his own. Though we are both busy, we still try to make time for each other. The other day, we met for coffee. While paying for our coffee, his wallet dropped on the ground and something fell out. Suddenly, a flood of memories washed over us as he put back his treasure into wallet—the blue silk with gold threads woven through it.

    Hot spots of drones (无人机) in Australia are getting sensors to automatically identify the aircraft and their pilots. Australia's Civil Aviation Safety Authority (CASA) said it would fix the equipment at the nation's airports starting next month. The monitors have been planned for some time, but come in the wake of 72 hours of drone-related disorder at the UK's Gatwick airport last week.

    In 2019, Australia will also start a scheme to register drone owners. The UK is also due to introduce a scheme in November that will require recreational drones weighing 250g (0.55lb) or more to be registered.

    Almost 140,000 air travellers were delayed last week after reports of drone sightings caused huge delays at Gatwick Airport. UK police are still searching for the criminals, although they have also raised the possibility that witness reports of the aircraft were mistaken. The incident “highlights” the need for a drone-spotting capability (能力), CASA spokesman Peter Gibson told the news agency Agence France-Presse. The supervision system would be able to spot the types of drone being flown, read their serial numbers and work out where the pilot was located, he said. Efforts to identify pilots would be aided by the introduction of the registration scheme for commercial and casual drone owners, he added. “2019 will witness severe action towards drone safety,” said Mr. Gibson. As well as airports and other sensitive locations, the drone-spotting systems will be fixed in other places known to be popular with drone owners such as the Sydney Harbour Bridge.

    Authorities in Australia have expressed worries about the number of drones being flown in controlled areas in recent months. Anyone breaking rules could face fines of up to 10,000 Australian dollars ($7,058; £5,600) as well as checks on the safety of their craft. “In 2019 it could be very expensive doing the wrong thing with your drone,” said Mr. Gibson. Events at Gatwick were discussed by ministers in a Christmas Eve phone conference. It is understood that the Cabinet Office “pushed” the Ministry of Defence and the Home Office to update their relevant regulations. They also discussed defence systems across the UK's airports.

    I can proudly say that last year I broke the record for the oldest person in the world to ride a roller-coaster. I'm 105, but I feel younger. Even the doctor agrees I'm in good condition. I'm a bit deaf and my legs feel weak, but they are the only issue.

    I rode the Twistosaurus at Flamingo Land, which spins you round quite fast. I didn't choose to go on that. I'd have preferred a really fast one that went upside down. But I was told I couldn't ride something like that, because my blood pressure could drop and I might have some danger.

    I wasn't nervous — I don't get frightened of anything. I was securely fastened, so I knew I wouldn't fall out. The roller-coaster ride went on for three or four minutes, and it couldn't be a better experience. And I raised a lot of money for the Derbyshire, Leicestershire & Rutland Air Ambulance fund, which was fantastic.

    People were saying I'd got a place in the Guinness World Records. Later, someone came to present me with the certificate. I had it on the wall in my living room, with another one that got a year earlier.

    My record-breaking ways really began a couple of years ago, with the ice-bucket challenge. It turned out that I was probably the oldest person in the world to do it, and the video was very popular. After that, I started to think about what else I could do to raise money for different charities.

    I'm not sure if anyone admires all the fun I'm having. They just say I'm daft and that's about it. But I've had many good days and many exciting times. I've had a really good life. I don't think I've wasted any of it.
