If you live in a city, then it's easy to take internet connectivity for granted, but in more rural areas,it is a different story. Connectivity is uneven. As of 2018, the last time figures were published, seven per cent of rural households could not access broadband faster than lOmbps,despite the average speed in cities being 52mbps. Around the wcrld, there are still huge areas of territory, from deserts to oceans, that the internet is still yet to reach.
But the urban/rural divide could be set to disappear over the next few years thanks to rocket company Spacex and an astonishingly ambitious project called Starlink. The aim is to use thousands of satellites in orbit above our heads to deliver broadband-comparable internet speeds to literally everywhere on Earth, with no need for expensive wires, transmitters or other infrastructure on the ground. Claims have been made that it could reach speeds of up to lGbps, which is 20 times faster than what most British homes receive today.
Spacex will need to launch thousands of satellites to fully complete the network over the Earth. At present, there are only around 2,000 or so other satellites in Lower Earth Orbit in total. So if Starlink's ambitions are realised, it could double or triple the number of satellites in orbit. So far, just over 700 have been successfully launched by the company and the first internet connections using the system are already being tested.
It is likely that over the next few years, Starlink could begin to offer ground-station satellite receivers that will connect to' the satellites and then, in turn. you could connect your computer or phone to that However, not everyone loves Starlink. There is one drawback to having so many satellites in orbit around the Earth : they risk making life a lot more difficult for astronomers
Ultimately though, for all of the protestations, it is surely unavoidable that Starlink, will become an essential part of Earth's telecommunications backbone. The obvious usefulness of such a network 'would be just too exciting for governments, businesses ,and individuals to resist. The urban/rural digital divide will no longer exist.

The Information Highway is the road that links computer users to a large number of on-line services: the Web, e-mail, and software, to mention just a few. Not long ago, the information Highway was a new road, with not many users. Now, everyone seems to want to take a drive, with over 30 million families connected worldwide. Not surprisingly, this well-traveled highway is starting to look like a well-traveled highway. Traffic jams can cause many serious problems, forcing the system to close down for repair. Naturally, accidents will happen on such a crowded road, and usually victims are some files, gone forever. Then, of course, there’s Mr. Cool, with his new broad-band connection, who speeds down the highway faster than most of us can go. But don’t trick yourself; he pays for that speeding.

【推荐2】China will continue to improve its policies and beef up support to speed up commercial use of the 5G network, an official with the country’s top industry regulator said on Tuesday.
Wen Ku, a spokesman for the Ministry of Industry and Information Technology, said the ministry will continue to support the development of the super-fast fifth-generation wireless technology by telecom carriers and encourage local authorities to come up with more support policies.
Chen Zhaoxiong, vice-minister of Industry and Technology, said that the development of the 5G network could give rise to massive opportunities in industrial growth and job creation. The ministry will make continuous efforts to promote the use of 1000Mb broadband connections and expand the coverage of fiber-optical broadband services, he said. Meanwhile, the ministry will upgrade telecom networks and operation systems by the end of November to ensure that mobile phone users nationwide can switch service carriers without changing phone numbers, he said. He explained that it could require substantial (大量的) efforts as it involved the upgrading of operation systems of a total of 1.6 billion users in the country.
In the meantime, a “floor-price” will be set for low-income and elderly populations to further promote mobile networks, he said. In order to better protect the rights of consumers, the number of service packages offered by the telecom carriers will be trimmed(削减)by more than 15 percent this year, according to Wen. Carriers are also required to make public all their service packages and make them all available for the users, he added. “We will step up investigations on wrongdoings so that consumers can see their telecom bill plain and clear,” he said.
China has expanded the download speed of mobile broadband sixfold compared with five years ago, while the charges for broadband connections and mobile Internet were down by 90 percent, according to the Ministry of Industry and Information Technology.
China’s digital economy reached a total volume of 31 trillion yuan ($4.5 trillion), or 34.8 percent of its GDP, in 2018, according to the ministry.

【推荐3】One of the biggest ideas in computer technology is cloud computing. The system is changing the way information is kept. It uses a group of computers or servers to store information instead of one. The data floats around like clouds instead of being saved on any computer. It means computers can be smaller than ever and store practically unlimited amounts of information. No longer are bulky computers needed because all the information is in the clouds.
So when will cloud computing start affecting the way you use computers? You may not have noticed, but it already has. Facebook, Amazon, Twitter and many other sites all run on cloud computing. Cloud computing is really useful. You can use it to access the same file at work at home or in other countries on different computers. There may even be environmental benefits, too. Gmail, which uses cloud computing, says that the system saves a lot of energy.
However, potential problems do exist such as losing information and not being able to access certain files when the internet is down. Also, some companies charge fees for their cloud computing services. Another major problem is security. If all your Information is out there in the cloud and not safely stored on your own computer or laptop, it may be possible for other people to access it. More and more of our personal information is in danger of being stolen. Therefore, it is important to be careful and to find ways of making the information secure.
More and more companies are starting up and offering cloud computing. Will the company be reliable? What will happen to your data if the company goes out of business? There are real worries. Even so, for those interested in computing technology, one thing is for certain ---the future in the clouds is going to be very exciting.

【推荐1】The success of The Pickwick Papers made Dickens very popular. He suddenly found himself at twenty-four the most famous novelist of his day. Busy as his social life was, he worked on two novels at the same time—Oliver Twist and The Pickwick Papers. He was particularly proud of The Pickwick Papers, which was a huge success and was regarded as a comedy (喜剧) masterpiece (杰作). “If I were to live a hundred years and write novels in each, I should never be so proud of any of them as I am proud of The Pickwick Papers,” he said.
It has been said of Dickens that he grasped (抓住) the imagination of his readers because his imagination grasped himself. The people in his works were so real that they could make him laugh or cry. When writing Oliver Twist he said that he could not rest until Fagin, the wrongdoer (做坏事的人), had been hanged.
Dickens’ marriage to Catherine Hagarth, with whom he had ten children, ended unhappily in 1858. He started to travel about giving readings of his works. His interest in theater gave his novels the qualities that made them suitable for reading aloud on the stage. A tiring travel to the United States affected his health. On June 9, 1870, when he was working on a new novel, he died, as he had wished. He said he wanted to die working.

【推荐2】“Based on long-term earthquake records dating back to nearly 1900, the expected annual occurrence of significant comprises roughly 16 events. The 2023 Hatay earthquakes were among the most severe in recent history.” a researcher Ozer said in 2023.
The Hatay region of Turkey is located at the boundary between the Anatolian and Arabian plates. This region experienced a severe earthquake on February 6th, 2023, impacting various aspects of its buildings and cultural heritage. Over 50,000 people died, and the cost was more 104 billion dollars.
Following the significant destruction, a study conducted by Nizar Polat published in Springer Nature in 2023 examines the deformation (变形) of the Earth’s surface in several cities in the Hatay region. The study not only employs Unmanned Aerial Vehicles (UAVs) (无人机) to get high-resolution 3D modeling (高分辨率的三维建模), but also uses aerial imagery (航空图像) to analyze surface deformations and cracks in the bedrock. Results show 7 cracks ranging from 24.11 to 497.69 m in length.
Besides, analysis within the subsidence (沉降区) area is also used to reveal the extent of physical deformations. Two subsidence areas are identified, measuring 23,060.8m2 and 13,954.2m2 respectively, with height changes of up to 20m. The accuracy of the photos are proved with a Root Mean Square Error (RMSE) (均方根误差) of 4.6cm, indicating high accuracy.
This study reveals the value of drone-based high-resolution 3D modeling in revealing the earthquake-caused deformation and landscape changes. These findings have greatly improved the understanding of earthquake destructions in the Hatay area and provided more insights to future research and reduce natural disasters.

【推荐3】What was once science fiction is now a part of our everyday lives, as artificial intelligence (AI) is something that many of us live alongside. According to Statista, in 2019, 3.25 billion virtual assistants were used worldwide and that figure is predicted to be more than double by 2014.
AI is doing more for us than setting reminders, making recommendations, and offering us weather reports. In fact, it could be about to change the healthcare landscape entirely. It is estimated that one in eight people today use health apps regularly. And AI has more to offer.
Dr Emilia Molimpakis is a neuroscientist who co-founded thymia, a platform that uses AI powered games to help doctors spot depression.
“I was inspired to start thymia after seeing my best friend struggle with depression,” she says, “I saw her try to go through the psychiatric (精神病学的) system and fall through the cracks. Despite being seen by a psychiatrist, she ended up trying to take her own life. When that happened, I was the one who found her, and this experience impressed me.”
Aside from blaming herself for not recognizing the signs sooner, what she could not get her head around was how the psychiatrist should not see this coming. She realized that the tools psychiatrists used were still these old-fashioned, pen-and-paper questionnaires that have been found, time and again, to be subjective and not reflecting a patient’s actual mental health status. So, thymia was born.
But as we look into the future, what should we be aware of? Before we dive in head-first, there are still questions we need to answer. As Dr Molimpakis points out, it’s vitally important that AI tools used in healthcare must be trained on a diverse data set that is typical of all groups of people. It should also be used alongside, and in addition to, professional care—not as a replacement. We should also consider carefully how our health data is stored and used. These are topics that both users and professionals have a responsibility to consider.

【推荐1】Every year in May, art galleries and museums prepare shows to honor Leonardo Da Vinci, who died in France on May 2, 1519. He is remembered as one of the greatest artists and creative thinkers of all time. His most famous paintings are The Mona Lisa and The Last Supper.
Recently, researchers have been studying a painting-Landscape 8P which, they think, is Da Vinci's earliest-known artwork. They used special lighting to study the artwork and discovered there were two images, not one. One drawing is on the back of the piece, which dates back to August 5,1473.
The drawing on the front was painted when Leonardo was 21 years old. It shows a river valley and a castle outside the city of Florence. There is little left of the drawing on the back, perhaps because it was wiped off. Only a bridge over a river can be seen. But there is writing on both sides.
The writing on the front gives the date and goes from right to left. Some people would call this “mirror-writing”. It's a way Leonardo often wrote in his notebooks. The writing on the back goes from left to right and tells about an agreement, probably to produce a work of art.
Cecilia Frosinini is an art historian. She said, “Leonardo was born left-handed, but was taught to write with his right hand from a very young age. By looking at his writings, including from this drawing, we can see his right-handed handwriting is educated and well done.”
Experts compared the two handwriting samples(样本)and said they were both made by Leonardo. They show he could write well using his left hand or his right hand.
The drawing is known as Landscape 8P from its number in an art list. It will be part of an exhibit at Italy's Uffizi Gallery. The gallery director, Eike Schmidt, said by studying the drawing researchers gave us a new way of looking at Leonardo's drawing technique and his abilities in writing.

【推荐2】Peter Ripken loves literature and reads books by writers all over the world. He learned years ago that not all nations permit writers to express themselves freely. In fact, free expression can be quite dangerous in many places.
So, Ripken decided to act. He helped establish an organization, the International Cities of Refuge Network (ICORN), to protect writers. Its founders sought to persuade cities, not central governments, to give refuge to persecuted(受迫害的)writers. He was involved right from the beginning, from the mid-1990s, to set up this program.
Originally, he had a different view of his future as a young man. He thought of becoming a bookseller because of his reading obsession when he was 15. But he did not become a bookseller. Instead, in the late 1960s, Ripken began a five year stint as a manager in an aid organization working in Africa. But his love for the written word remained strong. He then worked for three years as a deputy editor for the Africa section at the Voice of Germany. Despite his love for the job, when asked to join an organization promoting African, Asian and Latin American literature, Ripken didn’t hesitate. He had fun travelling to literature conferences and holding workshops with publishers and authors. That’s why he did the job for 20 years.
Ripken grew up reading German authors. But his interest broadened to other European and American literature. Then, he found what he called books "outside the norm(常态)". This helped grow his interest in political developments in other regions.
In 2016,Ripken retired after several years as ICORN’s chairman. But he is still active in the organization. His goal is to increase the group’s capacity to protect and promote writers and artists at risk around the world. He said he hoped to be remembered as somebody who had promoted creativity and supported literature as a political tool and source of enjoyment.
