The problem of robocalls has gotten so bad that many people now refuse to pick up calls from numbers they don’t know. By next year, half of the calls we receive will be scams (欺诈). We are finally waking up to the severity of the problem 1 supporting and developing a group of tools, apps and approaches intended to prevent scammers from getting through. Unfortunately, it’s too little, too late. By the time these “solutions” become widely available, scammers will have moved onto cleverer means. In the near future, it’s not just going to be the number you see on your screen that will be in doubt. Soon you will also question whether the voice you 2 (hear) is actually real.

That’s 3 there are a number of powerful voice manipulation and automation technologies that are about to become widely available for anyone to use. At this year’s I/O Conference, a company showed a new voice technology able to produce such a convincing human- 4 (sound) voice that it was able to speak to a receptionist and book as reservation without detection.

These developments are likely to make our current problems with robocalls much worse. The reason that robocalls are a headache has less to do with amount than precision. A decade of data breaches (数据侵入) of personal information 5 (lead) to a situation where scammers can easily learn your mother’s name, and far more. Armed with this knowledge, they’re able to carry out individually 6 (target) campaigns to cheat people. This means, for example, that a scammer could call you from 7 looks to be a familiar number and talk to you using a voice that sounds exactly like your bank teller's, tricking you into “confirming” your address, mother’s name, and card number. Scammers follow money, so companies will be 8 (bad) hit. A lot of business is still done over the phone, and much of it is based on trust and existing relationships. Voice manipulation technologies 9 weaken that gradually.

We need to deal with the insecure nature of our telecom networks. Phone carriers and consumers need to work together to find ways of determining and communicating what is real. That might mean either developing a uniform way to mark videos and images, showing when and who they were made by, or abandoning phone calls altogether and moving towards data-based communications — using apps like FaceTime or WhatsApp, 10 can be tied to your identity.

Credibility is hard to earn but easy to lose, and the problem is only going to get harder from here on out.

【推荐1】How would you feel if you woke up and found your entire computer’s contents — including your photos, your recent documents — no longer 1 (access)? What if you found out that they had 2 (wipe) from your computer, leaving you with nothing but heartache?

Guess what? It happens to people every single day. Every day, people across the country head into their local Apple store in 3 (tear), broken computer in hand, praying as they wait in line that 4 expensive repair might, just might, recover 5 priceless, irreplaceable files. A few get lucky. But for the rest, there’s nothing anyone can do 6 (help).

Hasn’t happened to you? If your computer 7 (remain) unprotected, it will, and it’s only a matter a time. But thanks to recent breakthroughs in computer backup technology, you now have a number of options to prepare, and if you’re smart, when your computer 8 (crash), you shouldn’t have any problem 9 (get) 100% of your files back that same day. I’m not talking about an external hard drive. I’m talking about an online backup 10 (solve) that runs quietly in the background on your computer. If you have one installed, when your computer crashes, you’ll be just one click away from bringing your files back to life.

Quantum computer chips demonstrated at the highest temperatures ever

Quantum computing is heating up. For the first time, quantum computer chips 1 (operate) at a temperature above -272℃, or 1 kelvin. That may still seem frigid, but it is just warm enough to potentially enable a huge leap in the capabilities.

Quantum computers are made of quantum bits, or qubits(量子比特), 2 can be made in several different ways. One that 3 (receive) attention from some of the field’s big players consists of electrons on a silicon chip.

These systems only function at extremely low temperatures-below 100 millikelvin, or -273.05℃ -so the qubits have to be stored in powerful refrigerators. The electronics that power them won’t run at such low temperatures, and also emit heat that could disrupt the qubits, so 4 are generally stored outside the refrigerators with each qubit is connected by a wire to its electronic controller.

“Eventually, for useful quantum computing, we will need to go to something like a million qubits, and this sort of brute force method, with one wire per qubit, won’t work any more,” says Menno Veldhorst at QuTech in the Netherlands. “It works for two qubits, but not for a million.”

Veldhorst and his colleagues, 5 another team led by researchers at the University of New South Wales in Australia, have how demonstrated that these qubits can be operated at 6 (high) temperatures. The latter team showed they were able to control the state of two qubits on a chip at temperatures up to 1.5 kelvin, and Veldhorst’s group used two qubits at 1.1 kelvin in 7 is called a logic gate, which performs the basic operations that make up more complex calculations.

8 we know the qubits themselves can function at higher temperatures, the next step is incorporating the electronics onto the same chip. “I hope that 9 we have that circuit, it won’t be too hard to scale to something with practical applications,” says Veldhorst.

Those quantum circuits will be similar in many ways to the circuits we use of traditional computers, so they can be scaled up relatively easily 10 (compare) with other kinds of quantum computers, he says.

Innovations that will change the classroom

American schools are going high - tech. Many symbols we still associate with classrooms and learning, like chalkboards, pens, notebooks - even classrooms 1 --- are quickly becoming outdated.

As this week marks The Huffington Post’s 10th anniversary, we’ll take a look at some products that 2 (introduce) to classroom in the past decade and have the potential to change the educational landscape in the years 3 (come).

1. Remote Learning

Some schools are cutting down on snow days, thanks to technology. Rather than giving kids the day off 4 weather conditions are too dangerous for commuting, these schools are asking students to follow classroom lessons online.

Although kids 5 (hope) for a snow day may not particularly appreciate these advancements in digital learning, online lessons allow these kids to complete their coursework and still interact with peers. Some students with medical conditions 6 “go” to school via video conferencing or even with the help of robots enabled with video chat that they can control remotely.

2. eBooks

Discovery Education has been replacing traditional textbooks with original “techbooks” for six years. These “techbooks” can also be switched to Spanish or French, Kinney said, 7 allows some parents who don’t speak English to help their kids with their homework.

3. Educational Games

In-class gaming options have evolved to include more educational options. GlassLab creates educational games that are now being used in more than 6,000 classrooms across the country. Teachers get real-time updates on students’ progress as well as suggestions on 8 subjects they need to spend more time perfecting.

The Internet and other digital tools have some drawbacks. They’re often distracting, 9 most developments have exciting implications for the future. Over the last 10 years, technological innovations have made education more interactive, immediate and 10 (personalize), -- and have shown us the potential for more accessible and effective classrooms.
