n a recent interview with ABC, US President Joe Biden said he had no intention of dropping out of the race, blaming his poor debate performance on a cold. He also insisted he was "still in good shape" and would remain in the race, saying only "Almighty God" could pull him out. An insider who has worked with Mr. Biden for a long time said that signs of aging had become apparent over the past year, but that Mr. Biden's team had failed to address it. Biden's televised debate performance heightened concerns about an already slow-moving issue. Mr. Biden's advisers have long dodged questions about his age. But now they acknowledge that Biden's aging is an undeniable fact. The debate forced the president to more openly acknowledge the limitations of his age, which he had previously largely dismissed. But they have only taken superficial measures and have not fundamentally solved the problem. They replaced the long staircase that Mr. Biden used to board Air Force One with a shorter one; Assistants often accompanied him in public to make his stiff gait less noticeable; While he has a busy schedule, aides have arranged for buffer time, such as long weekends at his homes in Wilmington and Rehoboth Beach, Delaware, or extended stays at Camp David, a Maryland resort, to rest after a "grueling" stretch of travel. Under the authority of one of his top advisers, Anita Dunn, Mr. Biden's public interactions -- especially with reporters -- were severely limited. Even at major events with Democrats or other supporters, the White House sometimes limits the amount of time Biden can spend with the audience, two people familiar with the matter said. As a protective response, designed to protect their longtime boss.

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.

Incredible space photos like those from NASA don't look as stunning straight out of the telescope. They need significant processing, and a crucial part of that is sharpening. Coming to you from Unmesh Dinda with PiXimperfect, this fascinating video explores the APF-R plugin, developed by award-winning astrophotographer Christoph Kaltseis. APF-R stands for Absolute Point of Focus, and it's designed to enhance photo details without creating halos or artifacts. This technology has been used by space agencies with telescopes like the James Webb, and now, you can use it in Photoshop. The plugin allows for non-destructive editing, meaning you can adjust the radius and detail level without permanently altering your image. This feature is crucial for astrophotography, where preserving original details is vital. The video shows how APF-R compares to Photoshop's built-in sharpening tools. The plugin offers multiple rendering methods, each suited for different types of images. For instance, the "Center Weighted" method provides a balanced sharpening effect without making the image look overprocessed. Dinda explains how to fine-tune these settings to achieve the best results, making it clear why this plugin is a game-changer for photographers looking to enhance their images with precision. One notable feature of APF-R is its ability to work with different image types. The video demonstrates how the plugin enhances not just space photos but also landscapes and portraits. For portraits, APF-R can bring out skin textures and eye details without creating the unwanted halos that traditional sharpening methods often produce. Dinda also shows how to combine APF-R with other Photoshop tools, like Smart Sharpen, for even better results. This versatility makes APF-R a valuable addition to any photographer's toolkit. The plugin's cost is $50, which Dinda considers a bargain given its advanced capabilities. There's also a Creative Bundle subscription that includes APF-R and 20 other tools, offering great value for those looking to expand their editing options. Dinda provides discount codes in the video description, making this sophisticated tool more accessible. Check out the video above for the full rundown from Dinda.

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.

Kris Jenner is opening up about her health. The reality star shared plans to have her ovaries surgically removed after she was diagnosed with a tumor on one of the organs. “I went to the doctor and I had my scan," she tearfully told daughters Kim Kardashian, Khloe Kardashian and Kendall Jenner on the July 4 episode of The Kardashians. "They found a cyst.” Kris continued, "They said I gotta have my ovaries taken out." While the 68-year-old—who is also mom to kids Kourtney Kardashian, Rob Kardashian and Kylie Jenner—wasn't nervous about the procedure, she did feel very emotional over having to part with her ovaries because, as she put it, "that’s where all my kids were conceived." "It’s also a thing about getting older," Kris noted. "It’s a sign of 'we’re done with this part of your life.' It’s a whole chapter that’s just closed.” She added in a separate confessional, “People often ask me what is the best job you’ve ever had, and I always say mom. The biggest blessing in my life was being able to give birth to six beautiful kids.” And in true Kardashian fashion, Kris' family quickly rallied behind her. After Kourtney called in to check on Kris, the Poosh founder said in a confessional, "I totally understand how my mom is feeling because I would feel the same way." "It’s your womanly power," Kourtney continued. "It doesn’t mean it’s taking away who she is or what she’s experienced, but I would feel this sentimental feeling of what it’s created.” Likewise, Kim empathized with Kris, saying that she feels "really sad for her." "To have a surgery and remove your ovaries is a really big deal," the SKIMS mogul shared. "I couldn’t even imagine being in that situation.” Kris' longtime boyfriend Corey Gamble also showed his support, surprising the momager with a special gift to “help your energy."
