    These days having a best friend seems so important to girls. However I have learned that having one best friend is not the way to go. It's so much better to have many great friends.

    As I was coming into Middle School, I was really excited because my friend Jennifer was going to be in the same Middle School! At first things were great, she introduced me to her friend Amy and we had lots of fun together. Then things started to change. Jennifer was very controlling: I couldn't make new friends, and pretty soon being Jennifer's friend was a struggle.

    Jennifer wanted to be the "leader" of our little group. Amy and I were never partners with each other in class projects or gym; it was always, "Who gets the privilege（特权） of being Jennifer's partner." Amy and I both wanted to be Jennifer's number one.

    I always waited for Jennifer and Amy after classes. They chatted by Jennifer's desk as Jennifer packed her books up and I waited by the door. Sometimes when they left, they'd walk right past me. No "Thanks for waiting." No "Sorry we took so long." It was as if they couldn't even see me.

    After months of living through school this way, I had really changed. I was moody, depressed, lonely. I spent lots of days trying not to cry, I felt so left out.

    Finally, near the very end of the school year, I was so incredibly sick of having to battle for friendship. I stopped sitting with Jennifer at lunch and stopped waiting for her after class.

    It was tough at first, but now, I have tons of friends. We have fun and happy times together and I love them all to bits. It amazes me how easy our friendship is. There's no struggling to be on top. I wish Jennifer could understand. Maybe one day she'll look back at what happened and she'll change, but even though I lost a friend, I am a happier person.

    In 2009 a new flu virus was discovered. Combining elements of the viruses that cause bird flu and swine flu, this new virus, named H1N1, spread quickly. Within weeks, public health agencies around the world feared a terrible pandemic (流行病) was under way. Some commentators warned of an outbreak on the scale of the 1918 Spanish flu. Worse, no vaccine(疫苗) was readily available. The only hope public health authorities had was to slow its spread. But to do that, they needed to know where it already was.

    In the United States, the Centers for Disease Control and Prevention (CDC) required that doctors inform them of new flu cases. Yet the picture of the pandemic that showed up was always a week or two out of date. People might feel sick for days but wait before consulting a doctor. Relaying the information back to the central organizations took time, and the CDC only figured out the numbers once a week. With a rapidly spreading disease, a two-week lag is an eternity. This delay completely blinded public health agencies at the most urgent moments.

    Few weeks before the H1N1 virus made headlines, engineers at the Internet giant Google published a paper in Nature. It got experts' attention but was overlooked. The authors explained how Google could "predict" the spread of the winter flu, not just nationally, but down to specific regions and even states. Since Google receives more than three billion search queries every day and saves them all, it had plenty of data to work with.

    Google took the 50 million most common search terms that Americans type and compared the list with CDC data on the spread of seasonal flu between 2003 and 2008. The idea was to identify areas affected by the flu virus by what people searched for on the Internet. Others had tried to do this with Internet search terms, but no one else had as much data-processing power, as Google.

    While the Googles guessed that the searches might be aimed at getting flu information—typing phrases like "medicine for cough and fever"—that wasn't the point: they didn't know, and they designed a system that didn't care. All their system did was look for correlations(相关性) between the frequency of certain search queries and the spread of the flu over time and space. In total, they processed 450 million different mathematical models in order to test the search terms, comparing their predictions against actual flu cases from the CDC in 2007 and 2008. And their software found a combination of 45 search terms that had a strong correlation between their prediction and the official figures nationwide. Like the CDC, they could tell where the flu had spread, but unlike the CDC they could tell it in near real time, not a week or two after the fact.

    Thus, when the H1N1 crisis struck in 2009, Google's system proved to be a more useful and timely indicator than government statistics with their natural reporting lags. Public health officials were armed with valuable information.

    Strikingly, Google's method is built on "big data"—the ability of society to handle information in new ways to produce useful insights or goods and services of significant value. However,   ▲  . For example, in 2012 it identified a sudden rise in flu cases, but overstated the amount, perhaps because of too much media attention about the flu. Yet what is clear is that the next time a pandemic comes around, the world will have a better tool to predict and thus prevent its spread.

    Last year my children gifted me a stainless steel (不锈钢的) coffee plunger (法式按压咖啡壶). I love to start the day with a strong black coffee and couldn't wait to use it. I looked forward to the following morning's coffee making, knowing that I probably wouldn't smash (打碎) this plunger as easily as I had done so often in the past.

    But as I poured my first cup of coffee, the plunger spilled (洒出) all over the table. Thankfully no one was around to see my disappointed face! I kept trying, but each morning would see me wiping up the coffee. Then I realized that if I poured very slowly there would be no spilling.

    This was at first a very painful experience. My normal practice was to rush through breakfast so that I could get on with my day.

    But in time I learned not only to pour slowly but to enjoy the experience: the smell, the taste, and the stillness of a new day.

    It prompted (促使) me to reflect upon whether there were other areas of my life I was rushing through. Most of life, it seemed.

    I started to leave extra time to do even the most ordinary tasks. When shop owners would apologize for keeping me waiting, I'd say, "Not a problem, I'm not in a hurry." Even hanging out washing became pleasurable when a couple of extra minutes of standing still and listening to the birds singing in the trees around me became part of my routine.

    Besides, one of my favorite experiences living in the inner city for many years was sitting on the front doorstep of our home spending time with strangers. We sat on the steps, each of us with a cup of coffee in our hands, listening to each other's stories. It was one of the warmest things about living in a busy city. It was as if the world around us slowed to a pace (步伐) we could both handle.

    Stillness and quietness not only slow the pace of life, but also feed the soul, helping us to enjoy the world's small pleasures.

When your boss calls and tells you to send $100,000 to a supplier, be on your toes. It could be a fake call. As if fake emails weren't enough, on the rise now is the deep fake audio (虚假音频) that can be cloned to sound almost real and perfect and is easy to create. "It's on the rise, and something to watch out for," says Vijay Balasubramaniyan, the CEO of a company called Pindrop.

Balasubramaniyan stated during a safety meeting how easy it is to use machine to create sentences that a person probably never said from recorded words. "All you need is five minutes of audio, and you can create fake audio," says Balasubramaniyan. Then, he showed a database (数据库) of voices, typed a sentence, and connected it to a famous people's name on the list. A few seconds later, he clicked "play", and it sounded quite real.

More costly are fake phone calls, where cheaters are able to fake the phone number of real contacts and make calls that result in workers sending off lots of money. He mentioned the example of a United Kingdom energy company in 2019 that got attacked by deep fake audio in a call that asked a worker to send $243,000 to a supplier. Reported by the Wall Street Journal, the worker was directed to pay it within an hour.

Balasubramaniyan says if you were to get that kind of call from a "boss" be doubtful and ask to call back right away to prove authenticity (真实性). Besides this, in his opinion, companies need to use more safety measures for keeping up with deep fake artificial intelligence (AI) that produces phone calls and software to check authenticity versus fake calls. "This is a threat that's waiting to happen," he says. "It's a very small number now, but it's very real."
