One company offering such services is London-based start-up Status Today. Its AI platform relies on a regular supply of employee data, including everything from the files you access to when you use a key card. From this, it builds a picture of how employees normally function and signals any unusual performance. The idea is to spot when someone might become a security risk by doing something different from their usual behavioral patterns. “All of this gives us fingerprint of a user, so if we think the fingerprint doesn’t match, we raise a warning”, says Mircea Dumitrescu, the company’s chief technology officer.

The system also aims to catch employee actions that could accidentally cause a security breach (漏洞), like opening malware (恶意软件).“We’re not monitoring if your computer has a virus.” says Dumitrescu. “We’re monitoring human behaviors.”

But catching the security breach means monitoring everyone, and the AI can also be used to track employee productivity. “It seems like they are just using the reputation of AI to give an air of lawfulness to old-fashioned workplace surveillance (监视),” says Javier Ruiz Diaz of digital campaigning organization the Open Rights Group. “You have a right to privacy and you shouldn’t be expected to give that up at work.”

Exactly how companies use the system will be up to them, but it’s hard to shake the picture of an AI constantly looking over employees’ shoulders. “It will bother people, and that could be counterproductive if it affects their behavior,” says Paul Bemal at the University of East Anglia.

Phil Legg at the University of the West of England says it will never catch every security risk. “If people know they’re being monitored, they can change their behavior,” he says.

Today, with the huge range of camera apps on our smartphones, we’re all good amateur photographers, since the quality of smartphone images now nearly equals that of digital cameras.

The new ease of photography has given us a tremendous appetite for capturing the magical and the ordinary. We are obsessed with documenting everyday moments, whether it’s a shot of our breakfast, our cat or the cat’s breakfast. Even photo journalists are experimenting with mobile phones because their near invisibility makes it easier to capture unguarded moments.

In the past, magazines published unforgettable photos of important people and global events that captured our imaginations. These photos had the power to change public opinion and even the course of history. But if there are fewer memorable images today, it’s not because there are fewer good images. It’s because there are so many, and no one image gets to be special for long.

As people everywhere embrace photography and the media make use of citizen journalists, professional standards appear to be shifting. Before digital images, most people trusted photographs to accurately reflect reality. Today, images can be altered in ways the naked eye might never notice. Photojournalists are trained to accurately represent what they witness. Yet any image can be altered to create an “improved” picture of reality. The average viewer is left with no way to assess the accuracy of an image except through trust in a news organization or photographer.

The question of the accuracy of images gets even trickier when photojournalists start experimenting with camera apps-- like Hipstamatic or Instagram --- which encourage the use of filters （滤镜）. Images can be colored, brightened, faded, and scratched to make photographs more artistic, or to give them an antique look. Photographers using camera apps to cover wars and conflicts have created powerful images--- but also controversy. Critics worry that antique-looking photographs romanticize war, while distancing us from those who fight in them.

Yet photography has always been more subjective than we assume. Each picture is a result of a series of decisions-- where to stand, what lens to use, what to leave in and what to leave out of the frame. Does altering photographs with camera app filters make them less true? There’s something powerful and exciting about the experiment the digital age has forced upon us. These new tools make it easier to tell our own stories--- and they give others the power to do the same. Many members of the media get stuck on the same stories, focusing on elections, governments, wars, and disasters, and in the process, miss out on the less dramatic images of daily life that can be as revealing.

Who knows? Our obsession with documentation and constantly being connected could lead to a dramatic change in our way of being. Perhaps we are witnessing the development of a universal visual language, one that could change the way we relate to each other and the world. Of course, as with any language, there will be those who produce poetry and those who make shopping lists.

The idea of setting the clocks to move an hour of daylight from the morning to the evening during summer has been controversial throughout its history. People have argued that the practice saves energy, reduces crime, and prevents traffic accidents. Others are not so convinced, and studies conducted over the past decade have shown mixed results.

The idea was first put into operation in Germany during World War I(1914­1918) in an attempt to reduce coal supply during wartime. Britain soon followed with its own Summer Time but so did confusion and chaos, with some institutions following the changes and some simply ignoring them. One writer felt angry at the laws in a more poetic manner, expressing his dislike for being forced to favor the sun over the moon.

Despite the early controversy, 82 countries currently use DST. The United States moves its clocks forward an hour at 2 a．m. on the second Sunday in March and back an hour on the first Sunday in November. Some states, however, still do not apply DST, and in the past even some areas within individual states refused to observe DST while the rest of the state did.

It was originally thought that DST would reduce energy consumption as people would use less electric lighting in the evening due to the increased hours of daylight. However, recent studies have suggested that this benefit has been canceled out by the increased use of home air conditioners, which people use for longer on long summer evenings.

Brighter evenings have reduced the number of traffic accidents in countries which observe DST, but studies have also noticed a spike(剧增) in the number of accidents during the week after the clocks change, possibly due to the sudden interruption of people's sleeping patterns.

One certain good thing to come out of DST, however, happened in 1999, when a group of West Bank terrorists(on DST) delivered bombs to a cell in Israel(not on DST) but ignored the time difference when setting the timers for their bombs. The bombs went off one hour earlier than planned, killing three terrorists instead of the intended civilians.

【推荐3】Kids nowadays are growing up “connected”, learning to use technology at a surprising speed. Technology is a regular part of school now! Kids as young as Kindergarten are using smartboards, IPads, and computers to complete tasks in the classroom. Older children rely on the Internet for research, getting homework, sending work to teachers, and even accessing（ 获得） textbooks. In fact, today’s kids have been given the name “digital（数字）natives” because they are facing technology almost from birth, so new things have never been a greater challenge in the hands of our children. The Internet，Facebook, iPods, pictures and texting on cell phones and all of these are the ways kids communicate today. They have become a central part of their lives. It allows them a private life that most of us know very little about.

Kids just don’t think about the results of the new world of social networking and text messaging. They don’t think that it is dangerous to send a photo of a particular person to a foolish person, who might send it to some friends that may send it to a hundred others and the next thing you know, it’s on many Facebook sites and all over the Internet forever. They don’t think that way because they don’t have the life experience that we do. We have to help them.

The key to knowing how they manage this privacy（隐私） is our “connection” to them. How closely do we connect with our kids and pay attention to what they’re doing? And how often do we talk to our children... and really listen to them? If they believe in us and know that we will be there for them, they are more likely to follow our advice. If we talk openly about what we believe in, what we stand for, those values will become their own before long.

【推荐2】Nineteen Eighty-Four, a dystopian novel by George Orwell, was set in a totalitarian state where even the language they use is controlled. Adjectives are forbidden and instead they use phrases such as “ungood”, “plus good” and “double plus good” to express emotions. As I first read this I thought how impossible it would be in our society to have such vocabulary. However, the more I thought about it, the more I realised in its own way it's already happening. I type messages to my friends and alongside each is the obligatory (惯用的) emoji. I often use them to emphasise something, or to not seem too serious, or because this specific GIF conveys my emotions much better than I ever could using just words. And I wonder, with our too much use of emojis, are we losing the beauty and diversity of our vocabulary?

English has the largest vocabulary in the world, with over one million words, but who's to say what it'll be like in the future? Perhaps we will have a shorter language, full of saying “cry face” if something sad happens or using abbreviations like LOL (laugh out loud) or BRB (be right back) instead of saying the full phrase. So does this mean our vocabulary will shrink? Is it the start of an exciting new era? Will they look back on us in the future and say this is where it all began—the new language? Or is this a classic case of the older generations saying, “Things weren't like that when I was younger. We didn't use emoticons to show our emotions?”

Yet when you look back over time, the power of image has always been there. Even in the prehistoric era they used imagery to communicate, and what's even more incredible is that we are able to analyse those drawings and understand the meaning of them thousands of years later. Pictures have the ability to go beyond the usual limits of time and language. Images, be it cave paintings or emojis, allow us to convey a message that's not restrictive but rather universal.

【推荐3】Koko the gorilla knew over 1,000 signs based on American Sign Language, and used them to do everything from asking for food to joking around. Her trainer and long-term companion, Penny Patterson, thought Koko went further still, signing in novel ways and showing complex emotions. According to Ms Patterson, when a cat that Koko loved was killed in an accident, Koko signed: “Cat, cry, have-sorry, Koko-love.” When Koko died last month, some of her obituaries (讣告) mourned the gorilla who had “mastered American sign language.”

Then came the backlash, from linguists and experts in sign languages. Sign languages have complex grammars, equivalent to spoken tongues in expressiveness. Koko’s ability, it was pointed out, fell well short of a fluent human signer. Moreover, Ms Patterson was her interpreter, a role that invited the question of how much she was inferring what Koko “must have meant,” and explaining away random signs. It was hard to be sure: Ms Patterson preferred speaking to journalists over sharing her video and raw data about Koko with fellow researchers.

There is no doubt that animals communicate. Animals from one region can share sounds that differ from groups in another, leading researchers to talk of animal “dialects.” Then there are the remarkable achievements of Koko and her primate predecessors, including a chimp delightfully named Nim Chimpsky. Yet there is an important distinction between communication and language. Take the misleading term “body language.” It is sometimes claimed that words convey just 7% of meaning, and that body language and tone of voice do the rest. This wildly overstretches an old study which found that most emotional messaging — as opposed to the propositional kind — comes from tone and body language, especially when a neutral word such as “maybe” was used. But try conveying a fact like “It will rain on Tuesday” with your eyebrows, and the difference becomes clear. Language allows for clear statements, questions and commands.

Nim Chimpsky’s near-namesake, Noam Chomsky, has argued that people have a kind of “universal grammar”, and that all humankind’s languages are mere variations on a theme. Mr Chomsky has changed his mind repeatedly on what constitutes the core of human language, but one obvious candidate is syntax — rules, not just words, which allow the construction of a huge variety of meaningful utterances (所说的话). This capacity may even be infinite. Any statement in English, for example, can be made longer by adding “He said that …” at the beginning. This property is called recursion: a simple statement (“It’s cold”) is embedded in a more complicated one (“He said that it’s cold”). Human syntax also allows for hypotheticals (“If she hadn’t arrived …”), talking precisely about events distant from the present, and so much more.

That gorillas lack syntax should not blind humans to their magnificence. But the fact that Koko could communicate should not mislead observers into thinking she possessed language.

【推荐1】Many small-business owners watched recent revelations about Facebook with mixed emotions. Like most Americans, they were surprised to discover how much information the social media giant collected on its users. But when it comes to small business, Facebook is a transformative advertising platform for small businesses, not easy to replace.

Let's say you own a small seafood restaurant, and Tuesday nights are $1 oyster （牡蛎）nights. Traditional advertising methods cost a lot and must be planned long in advance, and ifs hit-or-miss as to whether you actually get in front of oyster eaters. With Facebook, on Tuesday morning, with a few clicks, you can target Facebook users in your Zip code who love oysters and eating out （and are over age 21, so they can buy drinks, which is why you have $1 oyster nights）. And you can do this for as little as S20.

In my work with small businesses for more than 25 years, I've never seen a more effective method of micro-targeting prospects. Though Facebook is an effective tool for small-business, advertising does not justify （证明合理）the company's collecting vast amounts of data or allowing users' data to be invaded.

"Our primary concern was people's experience on Facebook," said Dan Levy, Facebook's Vice President. "Our teams have also been speaking to small businesses, and they want to make sure we're addressing the situation, and we are."

One concern small businesses want Facebook to address is protecting their uploaded lists. No one wants their customers' information misused or accessed by others, especially competitors.

Small-business owners are rightfully concerned about privacy. They don't want Facebook to know everything about them, and they don't want their customer lists to be let out to others.

But small businesses don't want to lose this effective advertising medium, either. Most Facebook ads are not invasive or offensive. And many receivers may actually benefit from receiving highly targeted ads—after all, those oyster lovers like learning about Tuesday night— $1 oyster night.

【推荐2】Imagine looking at a view of mountaintops and wondering about the name of each peak. Suddenly, above each mountaintop, a name appears on the sky. The words are not written in smoke by skywriting planes. The words are actually not in the sky at all. They come from tiny computers in contact lenses (隐形眼镜).

Computers have become smaller and smaller over the decades. The first computers filled houses. Transistors (晶体管) and then chips allowed computers to become small enough to fit on a desktop, then a laptop, and finally a phone. When experimenting with further contraction in size, developers often have to deal with the limits of human eyesight, which control how small the computers can be and still present visible information.

One new solution employs microprojectors (微型投影机) to create a readable display (显示) for tiny computers. These machines project computer information onto any surface. Though an impressive breakthrough, there are potential problems. Such public displays can lead to privacy concerns; most people do not want their information displayed on a wall for everyone to see. Besides, these projectors are extremely expensive, and their screens give users headaches.

Babak Parviz, a researcher at the University of Washington, created another solution: inventing a screen visible only to a person wearing a contact lens. Parviz created a computer in a contact lens that uses the wearer’s field of vision as the display. To create the display, Parviz took ordinary soft contact lenses with a wirelessly controlled system. At some point, Parviz says, it will be possible to connect the lens to a remote personal computer device such as a cellphone or a laptop. By looking in a certain direction, the wearer sends the computer visual information about what he or she sees. The device then uses this information to point out the names of peaks.

These contact lenses are inserted and removed in much the same way as ordinary contact lenses. In addition, the computers in the lenses won’t block the wearer’s sight at all. Although now the computers are not on lenses treating eyesight problems, Parviz hopes that someday the technology will progress to that level.

【推荐3】As Shanghai prepared to introduce mandatory(强制的) garbage sorting on July 1, games and toys that examined fun ways to spread information about the garbage sorting were to encourage younger people to take action.

A 15-second video of a game went on Chinese social media. In the video, players wearing VR(虚拟) headsets saw four different types of trash can in front of them, and had to throw different types of garbage into the right buckets(桶) to get points. Although it was not the only VR game in the place, visitors lined up around the booth to explore it because of the garbage-sorting theme.

“As a Shanghai, I am in great need of this game. Maybe I won’t need to check how to categorize(分类) each piece of garbage on my phone while going through all my garbage every day if I play this game more often, ” said ZhouZhou, a young Shanghai. But some social media users in Shanghai have complained about the difficulty of sorting different types of garbage.

Wu Xia, founder and CEO of VitrellaCore, the company that created the game, said the idea was to provide an interesting way of learning about garbage sorting. “It’s simple and easy to understand. People can practice sorting garbage without actually going through their trash, and it is a more effective method than using paper materials when training volunteers,” Wu said.
