索尼A7R VI发布

近日,索尼正式推出新一代全画幅微单相机A7R VI,标志着高分辨率摄影技术迈上新台阶。过去,使用超高像素相机往往意味着在画质与便携性、处理速度之间做出妥协,而A7R VI则致力于打破这一瓶颈。该机型在保持约6100万像素高分辨率的基础上,大幅提升了连拍速度、自动对焦性能及动态范围表现,并引入了更先进的图像稳定系统,让摄影师在手持拍摄时也能获得清晰锐利的画面。此外,A7R VI还优化了视频拍摄能力,支持8K录制,满足专业创作者对静态与动态影像的双重需求。分析人士指出,随着计算摄影和AI辅助技术的普及,传统相机厂商正通过硬件创新维持竞争力,而A7R VI的发布或进一步加剧高端相机市场的竞争格局。 #索尼 #A7RVI #相机 #摄影 #科技新闻 #高像素

U.S. to tell partners they must pick sides in AI race with China

WASHINGTON – The U.S. is preparing to tell dozens of countries they must pick sides in the artificial intelligence race with China, warning they will be excluded from a U.S.-led AI coalition if ​they also sign up for Beijing’s competing framework, according to a U.S. official and an internal draft reviewed by reporters. Washington last year launched ‌the Pax ‌Silica initiative aimed at securing supply chains for AI models, semiconductors and critical minerals, amid a fierce technology rivalry ​with Beijing. About two dozen countries have joined, including Kazakhstan, a key potential source of critical minerals that has also joined China’s coalition, as well as close U.S. allies such as Japan, Australia and South Korea.
The AI Situation in Software Development

Random thoughts about prompting, context windows, compression, and working with AI. You want it to do something you have in mind, and you know how/what to do, or sometimes you don’t. Now there are 3 options: you tell it everything down to the details, every specific thing. Or you just tell it to do something at a high level and expect the thing to understand. Or you can go the middle way. I feel this is the go-to way, explaining the important parts that you think might be difficult for it. You can feed it examples. It’s a faster way to do things, but it depends on the example being close to what you want. All of these are time-consuming. Some you spend time before giving to AI, some after. A common pattern is easy for LLMs to implement, considering they must have seen it before in their training set, for example implementing user auth. A n
ew problem you’re imagining or telling it is of course hard for it and needs hand-holding. Then there’s the context window problem. You can’t just give a 3000-word, 4-page detailed dense spec and expect it to follow everything, and the larger the codebase, the less it can pack everything in, nor are the vast documents you can feed it worthwhile. Not only for writing detailed specs ~ you also want it to summarize patterns, draw conclusions from a large dataset, be it something like analyzing vast amounts of numerical data, for example a historical dataset for a stock. So the cost is on you: you still need to spend the time to write a detailed guide for your project, its goals and its issues, and more importantly the blueprint of the thing you want. Then there’s domain-specific expertise of AI models. You need to pick and choose the right one. As you work on bigger problems and as you integrate AI into your applications, a need for compression arises, packing as much useful information as possible, if not all, into your AI agent to solve a particular problem or to draw a conclusion, make a decision or whatever. I think there will be companies in this space that’ll do this effectively, or the model builders will just solve this once and for all. There must be feedback loops in terms of tests, tooling (purpose-built or otherwise), and refining its approach as the codebase grows large. And ways for improving the signal-to-noise ratio in your codebase. I feel that great explainers or natural teachers find it easy to engage with AI and produce better outputs. Bottom line: you still need to spend time. The implementation time is gone. Now the time you spend has shifted to designing the system upfront, changing assumptions, and refining your dev setup. But implementation is not really gone. I feel I am still implementing in words instead of code.
Secondhand book sales are booming. Is it because of AI?

4 hours ago Something mysterious has been happening in the world of secondhand books. Over the last few months independent booksellers have been observing a strange pattern of purchases which have seen scores of their novels being shipped to far-off warehouses. In a typical week, Stuart Manley, from Barter Books, in Northumberland, would sell two or three thousand books. But one recent single bulk order from a Canadian company equalled what he would expect to move in seven days. He says he has "never seen the like of this after 30 years in the second-hand book trade". Mr Manley is not alone. Booksellers from around the world have been reporting similarly unusual mega orders. They aren't sure what the final destination for their books is. But the suspicion is that they are not being bought for avid overseas rea
ders but instead something else with a voracious appetite for new information: AI. The idea that the secondhand sales boom is being driven by the explosive growth of AI can be traced back to a court ruling in the US. In 2025, a judge ruled using books purchased in this way to train AI software was not a violation of US copyright law. The decision was the result of a lawsuit brought against AI firm Anthropic by three authors. In his ruling, Judge William Alsup said Anthropic's use of the authors' books was "exceedingly transformative" and therefore allowed under US law. When court documents were unsealed last month it also emerged books were being destroyed in the process of training Anthropic's AI chatbot, Claude. "Claude is trained on a mix of publicly available web data, commercially acquired datasets, and data we generate ourselves," a spokesperson said. They insisted sourcing books for training was a widely used approach across the AI industry. "None of our data acquisition programs buy and destroy rare or antiquarian books," they added. Nonetheless, the idea that books are being pulped is causing unease. David Tobin, runs Walden Books in north London, has also had unusual sales. "In some ways it's very nice to sell some of these titles which haven't been sold for many years, but it would be sad if they are ultimately destroyed," he says. The court documents relating to the Anthropic case revealed the project of ingesting old books was referred to in internal company communications as "Project Panama." The documents indicated the company's aim was to "destructively scan all the books in the world". Destructive scanning is the process of shipping books to locations where they can be digitised at an industrial scale. It includes removing a book's spine so all the pages can be scanned rapidly - and the remains recycled. "A lot of mystery surrounds Project Panama," Manley, from Barter Books, says. "The name is new to me, but the reality of the project is not, and has been the subject of much discussion on the bookseller forums." He does not know that his books are being bought for it or similar projects by other AI firms. But he says it's also difficult to account for the sales, which appear random with "no rhyme or reason." They have varied from obscure Latin texts to cowboy novels. Experts say the diverse subject matter also points to AI, as unusual and rare texts could provide fresh material to improve the training of large language models, the tech which underpins generative AI tools like chatbots. Professor Emily Hudson, intellectual property specialist at Oxford University, says copyright laws in the UK are different to those in the US. "The starting point in the UK is that all these acts of copying - creating the training library and doing the training – require the permission of the copyright owner," she says. For the booksellers, it poses a dilemma. They are uncomfortable with the idea of books being destroyed - even if they admit not every title needs to be saved. "A recent academic text published in only 100 copies, 75 of which are already in libraries, may be very rare on the market - but it is perhaps not such a great loss if one copy is destroyed," says Derek Walker, owner of Edinburgh bookshop McNaughtan's. "But we have, and have sold, books which are for example the only known surviving example of an edition from the 18th century. "It would be a much more significant problem if one like that were to be bought for
