You’ve been around forever. I can remember all the pain you’ve caused for me.

Do you remember the night you almost took my father’s life? I do. He loves you. Sometimes I think he loves you more than he loves me. He’s addicted to you, to the way you promise to rid him of his problems only to cause more of them. You just sat back and laughed as his car went spinning through the street, crashing into two other cars. He wasn't the only one hurt by you that night.

Do you remember the night of my first high school party? You were there. My friends were intrigued by you. They treated you as if they were never going to see you again, drinking all of you that they could. I spent two hours that night helping my friends who had fallen completely. “I’m so embarrassed,”they said as I held their hair back so that they could vomit . “I’m sorry,”they said when I called taxies for them, walking them out and paying the driver in advance. “This won’t happen again,”they said as they were sent to the hospital to have their stomachs pumped. Two 15- year-old girls slept in hospital beds that night thanks to you.

Do you remember the night when you took advantage of my 17-year-old neighbor who had to drive to pick up his sister from her dance lessons? Do you know how we all felt when he hit another car and killed the two people in the other car? He died the next morning too. His sister walked home from her dance lesson, and passed police cars and a crowd of people gathering on the sidewalk just two blocks away from the dance studio. She didn't realize her brother was in the midst of it all. She never saw him again. And it’s all your fault.

I wish you’d walk out of my life forever. I don’t want anything to do with you. Look at all the pain you’ve caused. Sure, you’ve made people happy too from time to time. But the damage you’ve caused in the lives of millions is inexcusable. Stop luring (引诱) in the people I love. Stop hurting me, please.

Sincerely, Anonymous

【推荐2】In fairy tales, it’s usually the princess that needs protecting. At Google in Silicon Valley, the princess is the one defending the castle. Parisa Tabriz is a 31-year-old with perhaps the most unique job title in engineering-“Google Security Princess”. Her job is to hack into the most popular web browser ( 浏览器 ) on the planet, trying to find weaknesses in the system before the “black hats” do. To defeat Google’s attackers, Tabriz must first think like them.

Tabriz’s role has evolved dramatically in the eight years since she first started working at Google. Back then, the young graduate from Illinois University was one of 50 security engineers- today there are over 500.

Cybercrime ( 网络犯罪 ) has come a long way in the past decade-from the Nigerian Prince Scam to credit card theft. Tabriz’s biggest concern now is the people who find bugs in Google’s software, and sell the information to governments or criminals. To fight against this, the company has set up a “Vulnerability Rewards Programme”, paying anywhere from $100 to $ 20,000 for reported mistakes.

It’s a world away from Tabriz’s computer-free childhood home in Chicago. The daughter of an Iranian-American doctor father, and Polish-American nurse mother, Tabriz had little contact with computers until she started studying engineering at college. Gaze across a line-up of Google security staff today, and you’ll find women like Tabriz are few and far between ( 稀 少 的 )- though in the last few years she has hired more female tech geniuses. She admits there’s an obvious gender disequilibrium( 性别不平衡 ) in Silicon Valley.

Funnily enough, during training sessions, Tabriz first asks new colleagues to hack into not a computer, but a vending machine ( 自动售货机 ). Tabriz’s job is as much about technological know-how as understanding the psychology of attackers.

【推荐3】David Unaipon was an inventor and writer. He was the first Aboriginal (土著的) Australian to write published books. He also worked hard to make life better for Aboriginal people.

David Unaipon was born in South Australia, in 1872. As a young man, he loved to read and was interested in science and music. He thought a lot about new ways to fix engineering problems. Between the years 1909 and 1944, Unaipon made nine important inventions. He also made drawings for a helicopter design. He got the idea from the Australian boomerang (回飞镖) and the way it moved through the air. This happened in 1914, before we had helicopters.

Unaipon lived most of his life in Adelaide and worked for the Aborigines’ Friends’ Association. He worked and travelled around southeastern Australia for fifty years. Sometimes, while travelling from town to town, he was told he couldn’t stay in a hotel because he was black, so he understood the problems of racism (种族主义).

In 1925, Unaipon became the first Aboriginal writer to be published. His first published writing was an article in Sydney’s Daily Telegraph newspaper. The article had the title:“Aboriginals: Their Traditions and Customs”. He wrote many other articles for newspapers and magazines, getting publicity about the rights of Aboriginal people. He also wrote about the need for white and black people to work together and the need for equal rights for both black and white Australians. He was well educated in both cultures, and in 1929 he helped with a government survey of Aboriginal health and interests.

David Unaipon died in 1967 at the age of 95, in the same year that Aboriginal people were first counted as part of Australia’s population. In 1995, David Unaipon’s picture was put on the Australian fifty-dollar note, with a drawing of one of his inventions.

【推荐1】Exploring the sands on the beach, Tonya III man came across a lidless boule. She picked it up, looked inside and noticed something. She turned it upside down. Out came a damp, neatly rolled piece of paper. Tonya took it home, dried and unrolled it.

What caught her eye was the year field, 18      . Though at first sceptical of finding something this old so easily, she continued reading. It began with some coordinates (坐标). Below was a request in German asking the bolded finder to put down the date and location of where it was found and return it to the nearer German embassy.

The Illmans took the note Rosa Anderson, a curator (馆长) at the Western Australian Museum. Soon Anderson called, saying he had been able to locate a 19th - century ship named Paula. Even more exciting was that experts in Germany were able to track down Paula’s logbooks and find a record by a “Captain O. Diekmann,” confirming that a bottle had been thrown overboard on June 12. 1886 - the date on the message. The sailor had also listed the coordinates of the ship’s location, which matched the ones on the note. Another evidence of the note’s truth was the logbook’s neat script (手稿), which paired perfectly with that of the handwritten message. The records also indicated that the bottle was one of the thousands thrown by the seamen back then as part of an experiment to track the water currents.

Anderson believes the note remained undamaged because it was put in a strong bottle with a narrow opening which allowed little water in, even after the lid came off. The expert guessed it had been probably washed ashore and remained buried in the thick sand.

The 131 - year - old note, now lying in the Western Australia Museum, was confirmed as the oldest message in a bottle ever discovered.

With little more than a pencil, a slide rule and one of the finest mathematical minds in the country, Mrs. Johnson, who died at 101 on Monday, calculated the precise track that would let Apollo 11 land on the moon in 1969 and, after Neil Armstrong’s history—making moonwalk, let it return to Earth.

Yet throughout Mrs. Johnson’s 33 years in NASA and for decades afterwards, almost no one knew her name.

Mrs. Johnson was one of several hundred strictly educated, supremely capable yet largely unrecognized women who, well before the modern feminist movement, worked as NASA mathematicians. But it was not only her sex that kept her long unsung. For some years at midcentury, the black women were subjected to a double segregation (隔离)：They were kept separate from the much large group of white women who in turn were segregated from the agency’s male mathematicians and engineers.

Mrs. Johnson broke barriers at NASA. In old age, Mrs. Johnson became the most celebrated of black women who served as mathematicians for the space agency. Their story was told in the 2016 Hollywood film Hidden Figures, which was nominated for three Oscars, including best picture.

In 2017, NASA dedicated a building in her honor. That year, The Washington Post described her as “the most high- profile of the computers”—“computers” being the term originally used to describe Mrs. Johnson and her colleagues, much as “typewriters” were used in the 19th century to represent professional typists.

She “helped our nation enlarge the frontiers of space,” NASA’s administrator, Jim Bridenstine, said in a statement on Monday, “even as she made huge steps that also opened doors for women and people of color in the universal human quest to explore space.”

As Mrs. Johnson herself was fond of saying, her term at Langley—from 1953 until her retirement in 1986—was “a time when computers wore skirts.”
