Old Thames barges have been sunk in an estuary to reduce erosion and create a new "island" habitat for birds, in a project the National Trust believes to be the first of its kind in the UK.
Deborah Alsina, chief executive of Arthritis UK, said: "This is a crushing blow for those individuals who have finally made it to the front of the orthopaedic surgery queue after a long time waiting.

那条小巷，就是我自由的“后花园”。我们在小水潭捉蝌蚪，到姐姐家里看《还珠格格》，去对面邻居家玩小霸王，在树下跳皮筋，元宵节用酒盒自制灯笼后排成小队“出街”……
Many people reading this will call bullshit on the performance improvement metrics, and honestly, fair. I too thought the agents would stumble in hilarious ways trying, but they did not. To demonstrate that I am not bullshitting, I also decided to release a more simple Rust-with-Python-bindings project today: nndex, an in-memory vector “store” that is designed to retrieve the exact nearest neighbors as fast as possible (and has fast approximate NN too), and is now available open-sourced on GitHub. This leverages the dot product which is one of the simplest matrix ops and is therefore heavily optimized by existing libraries such as Python’s numpy…and yet after a few optimization passes, it tied numpy even though numpy leverages BLAS libraries for maximum mathematical performance. Naturally, I instructed Opus to also add support for BLAS with more optimization passes and it now is 1-5x numpy’s speed in the single-query case and much faster with batch prediction. 3 It’s so fast that even though I also added GPU support for testing, it’s mostly ineffective below 100k rows due to the GPU dispatch overhead being greater than the actual retrieval speed.
