China launches satellites to start building the world's first supercomputer in orbit
China has launched the first batch of satellites for its space
computing constellation, a system that could rival the most powerful ground-based supercomputers once fully deployed.
Twelve satellites, each equipped with intelligent computing systems and inter-satellite communication links, were sent into orbit aboard a Long March 2D rocket from the Jiuquan Satellite Launch Centre around noon on Wednesday, according to state-owned Guangming Daily.

They are part of the Three-Body Computing Constellation, space-based infrastructure being developed by Zhejiang Lab. Once complete, the constellation would support real-time, in-orbit data processing with a total computing capacity of 1,000 peta operations per second (POPS) – or one quintillion operations per second – the report said.
Jonathan McDowell, a space historian and astronomer at Harvard University, said the idea of cloud computing in space was 'very fashionable' right now.
'Orbital data centres can use solar power and radiate their heat to space, reducing the energy needs and carbon footprint,' he said.
China, the United States and Europe could be expected to deploy such orbital data centres in the future, McDowell said.
'Today's Chinese launch is the first substantial flight test of the networking part of this concept.'

AI scientist De Kai offers a new vision for ‘parenting' AI to avoid our own demise
For years, the story of artificial intelligence (AI) has been cast as a high-stakes contest between the US and China – a technological arms race with global consequences. But to De Kai, a pioneering machine learning scientist and advocate for AI ethics, this framing fundamentally misunderstands the technology. 'I would prefer to think about it as the AI climate change challenge,' De Kai said in an interview with the Post at the Hong Kong University of Science and Technology, where he is a professor of computer science and engineering. 'Literally, AI is a change to the [social] climate that humanity is competing in.' De Kai, whose surname is Wu but who professionally goes by only his given name, has spent four decades at the forefront of AI research, going back to his work in natural language processing during his PhD at the University of California, Berkeley, in the early 1980s. His new book, Raising AI: An Essential Guide to Parenting Our Future, released on June 3, argues that living with AI requires a paradigm shift – one in which people 'parent' these systems as if they were their children. 'What's the single thing in folks' lives that makes them most want to become better versions of themselves?' De Kai writes. 'Having kids, most grown folks say.' Since AI is learning by absorbing everything we do and say online, we need to be conscientious about who we are around our AI 'children', the argument goes. De Kai's book Raising AI makes an argument for treating AI as children that must be parented by good role models.

Chinese social media giant RedNote opens Hong Kong office, its first outside mainland
Chinese social media giant RedNote has opened an office in Hong Kong, its first outside mainland China, a move the city's finance chief hopes will provide a boost to local businesses and the platform's international expansion. Financial Secretary Paul Chan Mo-po said on Saturday that he had personally invited the company, also known as Xiaohongshu, to set up a base in the city. 'When I visited Shanghai at the end of last year, I made a special visit to Xiaohongshu's headquarters,' Chan wrote on social media. 'I was deeply impressed by the team's youthful vitality and innovative spirit, and I invited them to Hong Kong to use it as a base to develop their international business.' Chan was officiating an opening ceremony, where he said the company's presence in Hong Kong would foster closer connections with the city's community, offering new perspectives and channels for local businesses in product design, marketing and promotion.

Chinese AR glasses maker Rokid prepares for global launch on AliExpress during 618 event
Rokid, a Chinese maker of augmented reality (AR) glasses, is set to launch its latest AR Spatial eyewear globally through Alibaba Group Holding 's AliExpress e-commerce platform, as the company pushes into overseas markets amid rising competition in the industry. The Hangzhou-based company will debut the glasses overseas on June 16 during the AliExpress 618 summer sale period this month, leveraging the e-commerce giant's 'BigSave' programme to offer a nearly US$100 discount, bringing the cost down to US$568 for a limited time, Rokid announced on Thursday. Alibaba owns the Post. The AR Spatial frames themselves weigh just 75 grams, but powering the glasses requires a portable hub containing a battery and a Qualcomm chip for handling spatial computing. The product allows three desktops to be viewed side by side and a 'cinema mode' that provides an experience the company likens to viewing a 300-inch screen. The partnership will see Rokid open an official store on AliExpress, joining other Chinese tech brands such as robotics maker Unitree , consumer electronics firm Anker, Labubu retailer Pop Mart , computer maker Lenovo Group , and smartphone giant Xiaomi in the BigSave initiative. The programme, launched last year, aims to help 1,000 brands surpass US$1 million in overseas sales this year, according to Alibaba. Rokid AR Spatial glasses can display three desktop environments at a time.
