ChatGPT: Explained to Kids(How ChatGPT works)

Chat means chat, and GPT is the acronym for Gene Rate Pre trained Transformer.

Genrative means generation, and its function is to create or produce something new; Pre trained refers to a model of artificial intelligence that is learned from a large amount of textual materials, while Transformer refers to a model of artificial intelligence.

Don't worry about T, just focus on the words G and P.

We mainly use its Generative function to generate various types of content; But we need to know why it can produce various types of content, and the reason lies in P.

Only by learning a large amount of content can we proceed with reproduction.

And this kind of learning actually has limitations, which is very natural. For example, if you have learned a lot of knowledge since childhood, can you guarantee that your answer to a question is completely correct?

Almost impossible, firstly due to the limitations of knowledge, ChatGPT is no exception, as it is impossible to master all knowledge; The second is the accuracy of knowledge, how to ensure that all knowledge is accurate and error free; The third aspect is the complexity of knowledge, where the same concept is manifested differently in different contexts, making it difficult for even humans to grasp it perfectly, let alone AI.

So when we use ChatGPT, we also need to monitor the accuracy of the output content of ChatGPT. It is likely not a problem, but if you want to use it on critical issues, you will need to manually review it again.

And now ChatGPT has actually been upgraded twice, one is GPT4 with more accurate answering ability, and the other is the recent GPT Turbo.

The current ChatGPT is a large model called multimodality, which differs from the first generation in that it can not only receive and output text, but also other types of input, such as images, documents, videos, etc. The output is also more diverse. In addition to text, it can also output images or files, and so on.

World's deepest diving pool opens in Poland, 45.5 meters deep
The world's deepest diving pool, Deepspot, opened this weekend near the Polish capital Warsaw. The 45.5-meter pool contains artificial underwater caves, Mayan ruins and a small shipwreck for scuba divers and free divers to explore. Deepspot can hold 8,000 cubic meters of water, more than 20 times the capacity of a normal 25-meter swimming pool. Unlike ordinary swimming pools, Deepspot can still open despite Poland's COVID-19 epidemic prevention restrictions because it is a training center that provides courses. The operator also plans to open a hotel where guests can observe divers at a depth of 5 meters from their rooms. "This is the deepest diving pool in the world," Michael Braszczynski, 47, Deepspot's director and a diving enthusiast, told AFP at the opening yesterday. The current Guinness World Record holder is a 42-meter-deep pool in Montegrotto Terme, Italy. The 50-meter-deep Blue Abyss pool in the UK is scheduled to open in 2021. On the first day of Deepspot's opening, about a dozen people visited, including eight experienced divers who wanted to pass the instructor exam. "There are no spectacular fish or coral reefs here, so it can't replace the ocean, but it is certainly a good place to learn and train safe open water diving," said 39-year-old diving instructor Przemyslaw Kacprzak. "And it's fun! It's like a kindergarten for divers."
Record numbers of people are flying. So why are airlines’ profits plunging?
New York CNN — A record number of passengers are expected to pass through US airports this holiday travel week. You’d think this would be a great time to run an airline. You’d be wrong. Airlines face numerous problems, including higher costs, such as fuel, wages and interest rates. And problems at Boeing mean airlines have too few planes to expand routes to support a record numbers of flyers. Strong bookings can’t entirely offset that financial squeeze. The good news for passengers is they will be spared most of the problems hurting airlines’ bottom lines — at least in the near term. Airfares are driven far more by supply and demand, not their costs. But in the long run, the airlines’ difficulties could mean fewer airline routes, less passenger choice and ultimately a less pleasant flying experience. Profit squeeze Industry analysts expect airlines to report a drop of about $2 billion in profit, or 33%, when they report financial results for the April to June period this year. That would follow losses of nearly $800 million across the industry in the first quarter. Labor costs and jet fuel prices, the airlines’ two largest costs, are both sharply higher this year. Airline pilot unions just landed double-digit pay hikes to make up for years of stagnant wages; flight attendant unions now want comparable raises. Jet fuel prices are climbing because of higher demand in the summer. According to the International Air Transport Association’s jet fuel monitor, prices are up 1.4% in just the last week, and about 4% in the last month. Adding to the airlines’ problems is the crisis at Boeing, as well as the less-well-publicized problems with some of the jet engines on planes from rival Airbus. Since an Alaska Airlines Boeing 737 Max jet lost a door plug on a January 5 flight, leaving a gaping hole in the side of the plane 10 minutes after takeoff, the Federal Aviation Administration has limited how many jets Boeing can make over concerns about quality and safety. As a result, airlines have dramatically reduced plans to expand their fleets and replace older planes with more fuel efficient models. In some cases, airlines have asked pilots to take time off without pay, and carriers such as Southwest and United have announced pilot hiring freezes. In addition to the problems at Boeing, hundreds of the Airbus A220 and A320 family of jets globally have also been grounded for at least a month or more to deal with engine problems. Just about all the planes with those engines have been out of sevice for at least a few days to undergo examinations. And Airbus has also cut back the number of planes it expects to deliver to airlines this year because of supply chain problems. Problems for flyers For now, competition in the industry remains fierce: There are 6% more seats available this month compared to July of 2023, according to aviation analytics firm Cirium. And that’s helped to drive fares down — good news for passengers, but more bad news for airlines’ profits. Southwest announced in April that it would stop serving four airports to trim costs — Bellingham International Airport in Washington state, Cozumel International Airport in Mexico, Syracuse Hancock International Airport in New York and Houston’s George Bush Intercontinental Airport. Many more cities lost air service during the financial hard times of the pandemic. While upstart airlines are driving prices lower for travelers, those discount carriers might not survive long term. As the major carriers are making less money, many of the upstarts are flat-out losing money.
The largest password leak in history exposes nearly 10 billion credentials
The largest collection of stolen passwords ever has been leaked to a notorious crime marketplace, according to cybersecurity researchers at Cybernews. This leak, dubbed RockYou2024 by its original poster “ObamaCare,” holds a file containing nearly 10 billion unique plaintext passwords. Allegedly gathered from a series of data breaches and hacks accumulated over several years, the passwords were posted on July 4th and hailed as the most extensive collection of stolen and leaked credentials ever seen on the forum. “In its essence, the RockYou2024 leak is a compilation of real-world passwords used by individuals all over the world,” the researchers told Cybernews. “Revealing that many passwords for threat actors substantially heightens the risk of credential stuffing attacks.” Credential stuffing attacks are among the most common methods criminals, ransomware affiliates, and state-sponsored hackers use to access services and systems. Threat actors could exploit the RockYou2024 password collection to conduct brute-force attacks against any unprotected system and “gain unauthorized access to various online accounts used by individuals whose passwords are included in the dataset,” the research team said. This could affect online services, cameras and hardware This could affect various targets, from online services to internet-facing cameras and industrial hardware. “Moreover, combined with other leaked databases on hacker forums and marketplaces, which, for example, contain user email addresses and other credentials, RockYou2024 can contribute to a cascade of data breaches, financial frauds, and identity thefts,” the team concluded. However, despite the seriousness of the data leak, it is important to note that RockYou2024 is primarily a compilation of previous password leaks, estimated to contain entries from a total of 4,000 massive databases of stolen credentials, covering at least two decades. This new file notably includes an earlier credentials database known as RockYou2021, which featured 8.4 billion passwords. RockYou2024 added approximately 1.5 billion passwords to the collection, spanning from 2021 through 2024, which, though a massive figure, is only a fraction of the reported 9,948,575,739 passwords in the leak. Thus, users who have changed their passwords since 2021 may not have to panic about a potential breach of their information. That said, the research team at Cybernews stressed the importance of maintaining data security. In response to the leak, they recommend immediately changing the passwords for any accounts associated with the leaked credentials, ensuring each password is strong and unique and not reused across different platforms. Additionally, they advised enabling multi-factor authentication (MFA), which requires an extra form of verification beyond the password, wherever possible, to strengthen cyber security. Lastly, tech users should utilize password manager software, which securely generates and stores complex passwords, mitigating the risk of password reuse across multiple accounts.
BRI: embracing Chinese green practices for a sustainable future
Editor's Note: This year marks the 10th anniversary of the Belt and Road Initiative (BRI) proposed by Chinese President Xi Jinping. Through the lens of foreign pundits, we take a look at 10 years of the BRI - how it achieves win-win cooperation between China and participating countries of the BRI and how it has given the people of these countries a sense of fulfillment. In an interview with Global Times (GT) reporter Li Aixin, Erik Solheim (Solheim), former under-secretary-general of the United Nations and former executive director of the UN Environment Programme, recalled how the BRI helped shorten a previously long journey in Sri Lanka to a half-hour trip. "We will all be losers in a de-globalized, de-coupled world. The BRI can play a key role in bringing the world together," Solheim said. This is the 18th piece of the series. GT: How do you evaluate the role of the BRI in promoting development in participating countries over the past 10 years? Solheim: The BRI has been a major driver of development since it was announced by President Xi Jinping in Kazakhstan 10 years ago. The China-Laos Railway has connected landlocked Laos to the Chinese and European rail network, making it possible for Laos to sell more goods and welcome more tourists. Rail corridors in Kenya and from Djibouti to Addis Ababa connect the interior of Africa to the coast, bringing opportunities for much faster development in East Africa. The Bandung-Jakarta railway in Indonesia, Hanoi metro, roads and ports in Sri Lanka - there are great examples of good south-south and BRI projects in almost every corner of the world. GT: In your experience of traveling around the world, has any BRI-related story left a deep impression on you? Solheim: Yes, many! I'll just mention two. When I was chief negotiator in the Sri Lanka peace process 15 years ago, it took a long time to travel from the airport to Colombo, the capital of Sri Lanka. When I came back last year, it took half an hour on wonderful Chinese-built highways. Traveling through Mombasa, a coastal city in Kenya, you see a lot of poverty and run down houses. Then all of a sudden, a green, clean, well-run oasis opens up. It's the end station of the Nairobi-Mombasa railway which links the capital Nairobi to the coast. The rail station stands out and is showing the future for Kenya. GT: The EU proposed the Global Gateway, and the US proposed the Build Back Better World. What do you think are the similarities and differences between these projects and the BRI? Solheim: I really wish success for the Western initiatives. What developing nations ask for is a choice of good cooperation with both China and the West. Unfortunately, up to now, a number of the Western-led initiatives have been more like media events. They lack structure, secretariat, finances and clear direction. Nearly all nations in the world want to see close people-to-people relations, investment and political cooperation with both China and the West. No one wants to choose. GT: Some people from the West are talking about "de-coupling" and "de-risking." Both seem to be another way of saying "de-globalization." Do you think "de-coupling" and "de-risking" will affect the BRI? And what role will the BRI play in maintaining globalization? Solheim: Decoupling is probably the most unwise idea in the world today. It's outright dangerous. Facing climate change, environmental degradation, economic troubles, war in Ukraine and other places, and the threat of pandemics, we need more, not less, cooperation. We will all be losers in a de-globalized, de-coupled world. The BRI can play a key role in bringing the world together. Almost all developing countries have made BRI agreements with China. As an example, when President Xi met all the leaders of Central Asia recently in Xi'an, Northwest China's Shaanxi Province, they made a very ambitious declaration on future green cooperation between China and Central Asia. GT: You have previously said that the BRI is a fantastic vehicle to promote green global development, which can boost the economy and ecology at the same time. Could you elaborate on how you think the BRI has achieved development of the economy and ecology? Solheim: In the beginning there were too many fossil fuel projects among BRI programs. In the BRI International Green Development Coalition, we argued this should stop. When President Xi pledged to stop building new coal-fired power projects overseas, it was one of the most important environmental decisions ever. Also, it happened at a time when important BRI nations like Bangladesh, Kenya and Pakistan decided they could grow their economies and go green without coal. The BRI will in the next decade become the world's most important vehicle for green energy and green transport. We will see massive investments in solar and wind power, hydrogen, electric batteries and more. GT: How do you view China's goal of achieving harmony between humanity and nature in modernization? In what way is China's story in pursuing harmony between humanity and nature relevant to other countries? Solheim: China now covers between 60 percent and 80 percent of all major green technologies in the world - solar, wind, hydro, batteries, electric cars and high-speed rail. Companies like Longi, BYD and CATL are the world leaders in their sectors. More remarkably and maybe less noticed abroad, China is also a global leader in protecting nature. It's embarking upon one of the most massive national park programs, with a focus on Qinghai Province and Xizang Autonomous Region. China is by far the biggest tree planter in the world and the global leader in desert control in Kubuqi, Inner Mongolia and other places. China has been hugely successful in the recovery of endangered species like the Giant Panda, Tibetan Antelope and Snow Leopard. A new center for mangrove restoration is being set up in Shenzhen and the fishing ban in the Yangtze will restore that magnificent ecosystem. The Belt and Road is a great opportunity for the world to learn from good Chinese green practices.
It may be getting harder to leave your smart wearable for the sake of your health
The world's first portable electrocardiograph was an 85-pound backpack, and now a 10-gram patch attached to your chest can transmit electrocardiograms uninterrupted for two weeks. The Apple Watch, which is worn by an estimated 100 million people, can send a text message to alert people when their heartbeat is irregular. Wearable sensors on the arms, wrists and fingers can now report arrhythmias, blood sugar levels, blood oxygen and other health indicators. Medical journals have also proposed a more ambitious vision - wearable devices can monitor patients with chronic diseases, eliminating the need for frequent hospital visits. They can spot potential health problems before a stroke or diabetes develops. The forces of health technology and wearables are converging. Tech giants like Apple (AAPL) and Alphabet's (GOOGL) Google are adding health features to their products. Medical technologists like electrocardiogram patch maker iRhythm Technologies or blood sugar monitor makers DexCom (DXCM) and Abbott Laboratories (ABT) are taking their devices beyond the clinic. "In the sensor world, people started on the consumer side and wanted to get into health care," said Kevin Sayer, chief executive of Decon Medical. "In health care, we're trying to be more consumer oriented, and I think all of those things are sort of colliding." Early bets favored the tech giants, with every health-related announcement from Apple, Google or Samsung Electronics hitting medical tech stocks. But changing doctors' practices will also require sustained investment in clinical trials. Big tech companies have cut back on investments in health care. Now it seems that medical technologists will be at the vanguard of the digital health revolution - with smartwatches and smart rings bringing them more customers who need to be diagnosed. Blake Goodner, co-founder of Bridger Management, a hedge fund focused on health care, said: "A group of medtech companies focused on digital health are maturing and reaching a scale where they can not only be profitable but also make investments to compete with larger tech companies." Tech giants aren't getting out of the health business. Apple's smartwatch has an electronic heart rate sensor that generates a single-point electrocardiogram, a wrist temperature sensor, and an accelerometer that can detect violent falls. Hundreds of millions of people are wearing smartwatches with health features from Apple or its rivals Samsung and Garmin.
