Now it’s gonna get asked on coding interviews…
world's first kilowatt-hour of nuclear fusion reactor "Xinghuo-1" project plans to complete construction by the end of 2029: using a "fusion-fission" hybrid reactor, and achieve demonstration power generation in 2030..
According to reports, the project uses "fusion-fission" hybrid reactor technology and a compact tokamak device based on high-temperature superconducting technology. The equivalent fusion power is greater than 40MW and the total power is 300MW, achieving 100MW-level grid-connected power generation of the hybrid reactor.

"so friend you just showed us you are knowledgable in html, css and js exactly what need for the job. But we need you to whiteboard implement this improved Dijkstra's algorithm for us, you have 25 minutes"

These days its more like: find the shortest path on weighted graph potentially containing negative cycles while traversing at most x edges while visiting each node at most y times. Also, write manual test cases covering all possible edge conditions and provide a rigorous proof for the runtime and space complexity of your algorithm. In addition, discuss how you would parallelize your algorithm to leverage multiple threads/processes. How would you scale your algorithm to handle 10B queries per second for a graph containing 10T vertices and 100T edges? Lastly, explain your back up and recovery strategy in case a computer your algorithm is running on experiences a catastrophic explosion. You have 2 minutes.

Chinese NeuraLink seems to be happening. Or at least whatever this Brain-Computer Interface industry develops into.
Another micron-level metal 3D printing manufacturer, Suzhou Dewu Technology, received 10 million yuan in angel round financing.
In August 2025, Hard Krypton reported that Dewu Technology, a precision SLM metal 3D printing company, had completed nearly 10 million RMB in angel round funding. This round was exclusively invested by Jiangsu High-Tech Innovation Angel Fund, with Zhuofeng Capital serving as long-term strategic financial advisor. The funds will be used for ultra-high-precision SLM equipment and process development, capacity expansion, and market expansion.
Dewu Technology was founded in May 2024 and officially began operations at the end of the year. It specializes in the research and development of ultra-precision manufacturing and industrial innovation applications using metal 3D printing (SLM) technology. Its business covers equipment development, AI+ design services, and printing services. The company serves the specialized manufacturing needs of industries such as consumer electronics, medical, intelligent manufacturing, aerospace, and humanoid robotics. The founding team, hailing from renowned universities such as Shanghai Jiao Tong University and Northwestern Polytechnical University, as well as leading manufacturing companies, possesses full-stack R&D capabilities, from equipment architecture and process paths to algorithms and industrial implementation. The team currently has over 20 employees, 80% of whom are R&D personnel.
