When it comes to the Internet, people talk about the password most. Actually, it's been under fire for a long time. Research has shown that passwords are not a very good way to protect sensitive information.

    People would use some random characters, numbers and symbols. Furthermore, a unique password would be used for every site or application the user uses. Unfortunately, the longer and more complex passwords become, the more people are likely to forger them. Therefore, they use the same password for every service or application. These are all big no-noes and essentially defeat the purpose of a password.

    Google is trying to kill off passwords on Android devices by introducing the Trust API, which does what simple passwords cannot and gives developers a framework for securing their application using a number of security systems and metrics(衡量标准)on the device. A Trust Score will be generated based on a number of metrics including your device location, face scanning, fingerprints, and the things like your typing speed or the way you speak. Taken one at a time, these metrics are not secure. But taken together, these metrics will help recognize the real “you”.

    The good news is that Google has already been testing this on real world data. Google has proven the Trust API works. Next Google will run tests will some banks to see if the Trust API meets their needs before rolling out the system on Android phones later. It may take another year for apps and popular sites to start using the Trust API.

    This is a pretty exciting change. Passwords have been around for a lone time. Although the security of systems has been improved, the usability of systems hasn't been proved much. Google appears to have the best of them. Maybe that never-ending conflict between security and convenience will be able to take a break once the Trust system comes out.

    My son has poliomyelitis (小儿麻痹)and he suffered from it a lot. When he was young, my wife and I took him to see so many doctors and got different kinds of treatments. But still, he couldn't walk like a normal kid.

    So he was laughed at by his peers for his walking style. His tears burnt our eyes like sulphuric acid (硫酸 ). Then, he became afraid of going to school. He wouldn't go anymore.

    One night, my wife had a breakdown and shouted at him, “I tell you, my kid, you might be like this forever. You are a freak in other people's eyes, and perhaps it would never change. But in my eyes, in your dad's eyes, you are not a freak! You are not! Even if you are, we love you and we will love you forever!” My son spoke nothing for two days. He didn't eat or sleep. We could read he was hurt. We hoped something wonderful would fall in our family. On the third morning, he struggled to walk to my car, with his school bag in his hand of course. He raised his head high and hugged me, saying “want to go to school. Nothing will beat me.”

    You know, from then on, he was never afraid of being mocked or despised anymore. If he couldn't avoid these looks, he chose to look at them in the eyes. Later, something nice really happened and my son went to MIT. When he was asked how he managed to bear the pressure, he said, “Because of my parents.”

    My dear fellows, if you care too much about how other people look at you or what their opinions are, you will never become what you want to be.

    “Don't tell anyone”. We hear these words when someone tells a secret to us. But it can be hard to keep a secret. We5re often tempted to “spill the beans"，even if we regret it later.

    According to Asim Shah, professor in the Menninger Department of Psychiatry and Behavioral Sciences at Baylor College of Medicine, US, keeping a secret may well "become a burden”. This is because people often have an “obsessive and anxious urge to share it with someone”.

    An earlier study, led by Anita E. Kelly, a scientist at the University of Notre Dame, US, suggested that keeping a secret could cause stress. People entrusted (受委托的)with secrets can suffer from depression, anxiety, and body aches, reported the Daily Mail.

    But with secrets so often getting out, why do people share them at all? Shah explained that people often feel that it will help them keep a person as a friend. Another reason people share secrets is guilt over keeping it from someone close to them. A sense of distrust can develop when people who are close do not share it with each other. "Keeping or sharing secrets often puts people in a position of either gaining or losing the trust of someone,” according to Shah.

    He added that talkative people could let secrets slip out (泄露). But this doesn't mean that it is a good idea only to share secrets with quiet people. A quiet person may be someone who keeps everything inside. To tell such a person a secret may cause them stress, and make them talk about the secret.

    Shah said that to judge whether to tell someone a secret, you'd better put yourself in their position. Think about how you would feel to be told that you mustn't give the information away. Shah also recommended that if you accidentally give up someone's secret you should come clean about it. Let the person know that their secret isn't so secret anymore.

    Once, a lioness and her cub were hunting in the jungle. The baby asked its mother, "Mother, why are we hunting when a deer is already at home?”

    The mother said, "My love! We can' t eat that deer because it has surrendered (投降) himself seeking our help. He is wounded and helpless. We must help him.”

    The baby cub was surprised and questioned again, "Why so? That's our food, we can eat it.”

    “Honey, you are right! It's our food and we can kill him in any second but do you think he deserves to be killed when he has come to-us for protection?”

    The baby cub couldn't understand her mother's vulnerability(软弱). It kept quiet and paced with its mother. At last, they didn't get anything and came back to their cave.

    The deer, on the other hand, was terrified of his own decision of taking shelter in the cave. Unfortunately he had no choice! He was attacked by a hunter and somehow managed to escape. While running for his life, he saw the cave and without a second thought entered it. He had already got a shot from the hunter. When he realized he was in the lions cave, he gave up the idea of running back again. The deer gazed at the lioness with a pitiful look, tears rolling down He sat there as if he urged for the mercy of the lioness.

    The lioness came closer to the deer, smelled it and slowly moved out of the cave with her cub.

    When the lions came back, the cub asked its mother to kill the deer again. But the lioness was firm on her decision. She said, "Sweetheart! We can-manage one night without any food. Tomorrow, I would definitely fetch out some food for you.”

    The cub said nothing, grunted(嘟哝）a little.

    When the cub slept, the lioness whispered to the deer, "Run, away from this area because I doubt if I could save you any longer if the next time situation demands!"

    The deer looked at the lioness with gratitude and slowly walked away from the cave.

    My six-year-old son, Stephen, was in front of the TV and smiled. His favorite show was about to begin-a Phoenix Suns basketball game.

    "Ladies and gentlemen," the announcer's voice was heard, "here is your starting lineup (首发阵容)." The arena (球场) darkened and the lights flashed when the players ran into the court to sing their team song. Stephen clapped and danced around. My wife Lorrie and I laughed. Stephen had been performing this for months. "One day I'm going to take you to a game, son," I promised.

    About a year later, the construction company where I worked finished a project for a Suns player. One afternoon my boss called me. "The player has two extra tickets for tonight's game! Just pick them up at my office," he said. I picked up the tickets, but felt a little disappointed when I looked at the clock. Even if I had had a helicopter, we would never have gone to the arena in time for the player introductions. Stephen would miss his favorite part! I grabbed my key, got Stephen in my car and hit the road. "Lord," I prayed, "I'd love to see the joy on Stephen's face. Help us make it on time."

    When I drove, it began to rain heavily. Suddenly, lightning flashed right near the arena! I turned on the radio to listen to the game. The announcer said there'd been a power failure at America West Arena. Everyone was fine, but there would be a delay until they got everything running. Finally, I parked the car and we walked in hurriedly to take our seats. I hoped that we hadn't missed the introductions.

    The very moment we entered the arena, the lights darkened. The music started. "Ladies and gentlemen, here's your starting lineup!" Stephen's eyes grew wide. There wasn't enough space for him to dance around, but I could tell that his heart was leaping more than his body was able to. Thank heaven, he hadn't missed a thing. And neither had I.
